Full textAbstract:
Performance related musculoskeletal disorders (PRMDs) are a frequent reality for practicing musicians. Many aspects of the bassoon make bassoon players particularly susceptible to PRMDs. This thesis explored the prevalence of PRMDs among bassoon players and assessed the frequency, types, and locations of PRMDs. Also identified were treatments used for PRMDs, contributing factors to PRMD development, and the perceptions of the bassoon community regarding PRMDs. The International Bassoonist Questionnaire was distributed via the World Wide Web (n = 166, 58% male, 42% female). Eighty-six percent of bassoon players reported PRMDs. Pain was the most common PRMD symptom reported (78%). Females reported PRMDs (96%) more frequently than males (78%). Younger bassoon players reported more PRMDs. Most bassoon players (88%) were attempting to treat their PRMDs. The most common self-administered treatments were rest (60%) and reducing playing time (53%). Bassoonists attributed the cause of PRMDs to “long hours of practice” and “sudden increase in playing time.” Bassoon players felt strongly that the medical profession did not know how to treat a bassoon related injury. They believed that a knowledgeable teacher was the best resource against the onset of PRMDs even though technical aspects of playing were not identified as significant contributors to PRMDs. The bassoon playing population needs more information about PRMDs in order to develop treatment and prevention strategies.

Full textAbstract:
Bakgrund: Fysisk smärta kan försämra både fysisk och psykisk förmåga samt leda till flertalet komplikationer. Smärta är ofta sammankopplat med skador. Skador är vanliga bland idrottare, och skaderisken ökar ju högre nivå man spelar på. Då skador är så pass vanliga bland idrottare på hög nivå så kan man anta att detsamma gäller med smärtkänningar. Eftersom smärta kan påverka en negativt på så många sätt så kan det vara intressant att undersöka smärta bland idrottare på hög nivå. Syfte: Syftet med studien var att undersöka upplevelsen av smärta samt relationen till smärta hos kvinnliga fotbollsspelare på hög nivå i Sverige. Metod: 68 från 4 olika lag i division 1 och 2 deltog i studien. De var mellan 14-30 år gamla och hade spelat på hög nivå mellan 1-13 år. En enkät användes för att samla datan och SPSS användes för att analysera den med deskriptiv statistik. Resultat: 50 % av spelarna skattade deras smärtutsträckning före, under och efter träning och match med 3 eller mer på en skala mellan 1-5, där 1 är "ingen utsträckning" och 5 är "hög utsträckning". Resultaten varierade angående vilken influens smärta haft på försktighet, förmåga, potential, känslor och koncentration. Spelarna kände dock att smärta haft störst påverkan på deras förmåga att spela och deras emotionella välmående. 42.65 % av spelarna fortsatte som vanligt när de upplevde smärta under träning och 44.12 % av dem fortsatte men tog det lugnare, medan 83.83 % fortsatte som vanligt när de upplevde smärta under match. Samtliga av deltagarna var av uppfattningen att det kan vara skadligt på olika sätt att spela trots att man känner smärta. Slutsats: De flesta av spelarna var negativt påverkade av smärta i någon grad. Även om de var övertygade om att det kan leda till problem om man spelar trots smärta så fortsatte de flesta att spela när de fick smärtkänningar under träning och match.Background: Physical pain affects mental performance as well as many physical factors and is often associated with injuries. Injuries are common among athletes and a higher level of play coheres with a higher prevalence of injuries. Since injuries are so common among high-level athletes, it is reasonable to assume that pain is also connected to the high level of play. Also, since experiencing pain has its side-effects, it is interesting to investigate physical pain among high-level athletes. Purpose: The purpose of the study was to investigate the presence and experience of pain among high-level female soccer players in Sweden, as well as their relationship to pain. Method: 68 players between 14-30 years old who had played at a high level for 1-13 years participated in the study. A questionnaire was used to collect the data and SPSS was used to analyse it with descriptive statistics. Results: 50 % of the players rated their pain extent before, during and after practices and games with 3 or more on a scale from 1-5, where 1 is “no extent” and 5 is “high extent”. The results were scattered regarding the influence pain had on carefulness, ability, potential, emotions and concentration, but the players felt that pain had the biggest influence on their ability to play and their emotional wellbeing. 42.65% of the players continue as normal when experiencing pain during practice and 44.12% of them continue but take it easier, while 83.82% continue as normal when experiencing pain during game. All of them thought that playing and practicing with pain could lead to future complications in some way. Conclusion: Most of the players struggled with pain to varying degrees. Even though being convinced that playing with pain can lead to complications, they kept on playing when they experienced pain themselves.

Full textAbstract:
Despite an exceptionally high prevalence of overuse injury among elite volleyball players, very little is known about the aetiology of these conditions. Fundamental movement patterns have been found to be predictive of serious acute athletic injury, however the relationship between fundamental movement patterns and overuse injury has yet to be determined. Sport-specific jumping biomechanics have been shown to play an additional role in the development of overuse injuries in sport, and it is likely that combining fundamental and sport-specific movement assessment may possess greater predictive power than either alone. The purpose of this investigation was to evaluate how volleyball-related overuse injuries are related to fundamental movement patterns and volleyball spike jump technique. We hypothesized that volleyball players with a history of overuse injury would exhibit more dysfunctional fundamental and sport-specific movement than players without a history of injury. Fifty-seven male and female collegiate volleyball players took part in Functional Movement Screen testing, and athletes free of lower body pain (n=31) took part in a 2-dimensional kinematic analysis of spike jump technique using Dartfish video analysis software. Volleyball players with a history of overuse low back injury had significantly lower Active Straight Leg Raise scores compared to healthy players (p=0.011). Various aspects of hip mechanics during the spike jump were significantly related to a history of shoulder, low back, and knee pain (p<0.01), and the Shoulder Mobility test was significantly correlated to 2 aspects of hip mechanics during the spike jump for females (R² = 0.560, p<0.01). Additionally, males with a history of overuse pain tended to jump 14 cm higher than their healthy teammates (p<0.01). Both fundamental and sport-specific hip mechanics appear to have a link to overuse injuries among collegiate volleyball players.

Full textAbstract:
Participation in athletics is a popular pastime and form of entertainment. Children often begin to specialize in one sport at a young age in an effort to excel, which increases physical stress and the potential for injuries. Athletes participating in overhead sports are at increased risk of upper body chronic injuries, in part because the shoulder is an unstable hypermobile joint. Posture may also be affected in these athletes because of the demands placed on the upper body. The purpose of this study was to measure the upper body posture in a sample of Division I collegiate volleyball and softball athletes to investigate the prevalence of postural abnormalities and their relationship to pain or injury.
Twenty-one Division I collegiate female athletes (seven volleyball; fourteen softball) who participated in their sport during the fall 2014 to spring 2015 seasons were studied. Athletes completed a pain and injury questionnaire, after which individual upper body posture measurements were made. Measurements included resting bilateral scapula position, head position, and shoulder position. An iPad mini camera was used with a commercial application (PostureCo, Inc.) to perform a photographic plumb line posture assessment with photographs taken in anterior, posterior, and lateral views.
Posture analysis revealed a high prevalence (85.7 %) of forward head posture in this sample. Forward shoulder was noted in 42.9 % of the athletes and abnormal horizontal scapula position appeared to occur more frequently in the dominant arm (71.4 %) than in the non-dominant arm (47.6 %). Chi square tests determined that there was no statistically significant relationship between posture abnormalities and self-reported pain in this group of athletes. Results of this study -- although preliminary -- should be used to inform future research to investigate potential relationships between posture and pain/injury in overhead athletes.

Full textAbstract:
The principal aim of the present thesis was to prospectively follow (clinical status and ultrasound + Doppler findings) the patellar tendons in the young elite volleyball players at the Swedish National Centre for high school volleyball in Falköping. In an Olympic weightlifter with chronic painful jumper´s knee, the effects of treatment with sclerosing injections followed by early instituted very heavy weightlifting training, was also evaluated. First, in a prevalence study, we demonstrated that the clinical diagnosis patellar tendinopathy-jumper’s knee, together with structural tendon changes and vascularisation in the painful area of the tendon, was demonstrated in 12/114 tendons in Swedish junior elite volleyball players, but not in any tendons of individually matched (age, height and weight) not regularly sports active controls. Structural tendon changes alone was demonstrated among the volleyball players but also among the controls. In a 7 months prospective study of a total of 120 tendons, we demonstrated that the clinical diagnosis patellar tendinopathy-jumper’s knee was associated with neovessels/vascularity in the area with structural tendon changes in 17/19 tendons. Seventy tendons that at start were clinically normal, and had normal ultrasound + Doppler findings, remained clinically normal after 7 months with intensive training and playing volleyball. In a 3-year prospective study it was demonstrated that normal clinical tests and normal ultrasound + Doppler findings at school start, indicated a low risk (8%) for these players to sustain patellar tendinopathy-jumper’s knee during the 3 school years with intensive training and playing. In a case study, involving an Olympic elite weightlifter with chronic painful patellar tendinopathy-jumper’s knee, successful treatment with ultrasound and Doppler-guided injection of the sclerosing agent polidocanol, allowed for pain-free very heavy weight training two weeks after treatment. Further heavy weightlifting training on a daily basis, preparing for European Championships, was done without causing tendon rupture and/or pain.

Full textAbstract:
Study Design. Cross-sectional survey among athletes competing at the collegiate level in basketball, swimming, and track and field, as well as a matched nonathletic control group. Objective. To compare the prevalence of low back pain between sports: basketball, swimming, and track and field, as well as nonathletic control group. Summary of Background Data. With conflicting reports, it is not clear whether athletes are at higher risk for low back pain when compared to nonathletic counterparts. Some literature has found that low back pain was less common in former elite athletes when compared to nonathletes; however, much of the literature supports that athletes experience more low back pain. Methods. Self-reported questionnaire on low back pain adapted for sports based on the Nordic questionnaires for musculoskeletal symptoms. Responders were 10 basketball players, 57 swimmers, 47 track and field athletes and 382 controls. Results. The main findings of the current study support previous literature displaying a greater prevalence of low back experienced in athletes when compared to age-and-sex matched controls. This study found a significant relationship of reported low back pain as age and weight increased. Conclusions. Athletes have a greater prevalence of low back pain when compared to their less athletic peers. A larger sample size could suggest a significant relationship between the prevalence of low back pain and training volume, training season and sport.

Metodologia: Realizou- se uma pesquisa computorizada nas bases de dados, PubMed, Web of Science e SPORTDiscus, com a combinação das seguintes palavras-chave (“prevention exercise” OR “prevention training”) AND (“groin injuries” OR “groin pain”) AND (“football players” OR “soccer players”) AND (physical therapy) de acordo com as guias do Prisma Flow Diagram. A qualidade metodológica dos estudos incluídos foi analisada através da Physiotherapy Evidence Database Scoring Scale (PEDro). Resultados: Nesta revisão foram incluídos 5 artigos que cumpriram os critérios de elegibilidade com um total de 1358 participantes e média aritmética de 7/10 na escala de PEDro. Verificou-se que o treino de prevenção promoveu, uma diminuição significativa do risco de lesão de pubalgia em jogadores de futebol masculino. Conclusão: Com base nos estudos analisados, parece ser possível afirmar que deve ser implementado um treino de prevenção para pubalgia, visto que parece existir uma diminuição do risco lesivo assim como o facto de potenciar a força excêntrica adutora da anca, bem como de otimizar o rácio da força excêntrica entre adutores-abdutores da anca.
Objective: To determine if the prevention training can promote a diminished risk and prevalence of groin injuries in male football players. Methodology: Computerized research conducted in the databases PubMed, Web of Science and SPORTDiscus, was performed using the combination of the following keywords: (“prevention exercise” OR “prevention training”) AND (“groin injuries” OR “groin pain”) AND (“football players” OR “soccer players”) AND (physical therapy) according to Prisma Flow Diagram. The including studies were analyzed using the Physiotherapy Evidence Database Scoring Scale (PEDro). Results: this review included 5 articles that met the eligibility criteria with a total of 1659 participants and with an arithmetic mean of 7/10 on the PEDro scale. It was found that the prevention training promoted a diminished prevalence and risk of groin problems in male football players. Conclusion: Based on the studies analyzed, seems to be possible to affirm that prevention training for groin injuries should be implemented, since there seems to exist a decrease in the risk of injury and also because of it enhances the eccentric hip adductor strength, as well as optimizing the ratio between eccentric hip adductor and eccentric hip abductor strength.

Dissertação de mestrado em Fisioterapia –
Ramo das Condições Músculo-esqueléticasINTRODUÇÃO: A dor no complexo articular do ombro (CAO) é uma queixa frequente em atletas overhead (OH). No voleibol, pela complexidade do gesto técnico, existe uma elevada prevalência de lesões de sobreuso. Para corrigi-las, a literatura atual foca-se em exercícios direcionados para a estabilidade dinâmica (ED) da escapulotorácica (ET) referindo que o biofeedback eletromiográfico (BEMG) quando adicionado a estes, traz benefícios. OBJETIVO: Testar a efetividade do BEMG adicionado a um programa de exercícios de ED nas variáveis, tempos de ativação muscular, intensidade da dor e funcionalidade, em atletas voleibolistas femininas com disfunções do CAO (DCAO). METODOLOGIA: As 19 atletas selecionadas foram sujeitas a um processo de aleatorização, obtendo dois grupos homogéneos, um que realizou o protocolo de exercícios (GEXC) e outro que realizou o protocolo de exercícios com recurso ao BEMG (GBEMG). Esta intervenção teve a duração de 8 semanas tendo sido realizadas três avaliações, uma inicial (T0), uma intermédia (T1) e uma final (T2). Foram avaliadas as variáveis em estudo numa tarefa lenta e numa balística. RESULTADOS: Numa comparação inter-grupos, pôde-se verificar que nos tempos de ativação, nas duas tarefas, em T1 e em T2, os resultados beneficiaram maioritariamente o GBEMG, assim como na dor e funcionalidade. Relativamente à comparação intra-grupo, houve resultados estatisticamente significativos: na tarefa lenta o trapézio superior (TS) apresentou uma ativação mais retardada, no GEXC e uma ativação mais precoce na tarefa balística, quer no GEXC (T1-T2) quer no GBEMG (T0-T2). Em relação à dor houve redução significativa da intensidade no GEXC (T0-T1) e GBEMG (T1-T2 e T0-T2), assim como na funcionalidade no GBEMG (T0-T2). DISCUSSÃO E CONCLUSÃO: Na generalidade, não se pode afirmar que o BEMG é benéfico quando adicionado a um protocolo de exercícios de ED nesta população, pois as diferenças entre os grupos ao nível das três variáveis não são estatisticamente significativas.
INTRODUCTION: Shoulder pain is a frequent complaint in overhead athletes. In volleyball, the complexity of the technical gesture is responsible for the high prevalence of overuse injuries in this joint. In order to treat these lesions, the current literature focuses on targeted exercises for dynamic stability of the scapulothoracic muscles, stating that electromyographic biofeedback when added to these exercises shows better results. AIM: To test the efficacy of electromyographic biofeedback when added to a dynamic stability exercise program in the variables, muscle onsets, pain intensity and functionality, in female volleyball players with shoulder dysfunction. METHODOLOGY: The 19 athletes went throw a randomized process, obtaining two homogeneous groups, one did the exercise protocol (GEXC) and the other the same protocol with electromyographic biofeedback (GBEMG). This intervention lasted for 8 weeks, with one initial assessment (T0), one after 4 weeks, in the middle of the intervention protocol (T1) and one at the end (T2). The study variables were evaluated in two tasks, slow and ballistic. RESULTS: In an intergroup comparison, it was verified that on muscle onsets, in the two tasks, in T1 and T2, the results benefited mainly GBEMG, as well as in pain and functionality. Regarding the intra-group comparison, there were statistically significant results: in the slow task the upper trapezius presented a more delayed activation in the GEXC and an earlier activation in the ballistic task, in GEXC (T1-T2) and GBEMG (T0-T2). In relation to pain, there was a significant reduction in intensity in GEXC (T0-T1) and GBEMG (T1-T2 and T0-T2), as well as in GBEMG (T0-T2). DISCUSSION AND CONCLUSION: In general, it can’t be said that electromyographic biofeedback is beneficial when added to a protocol of dynamic stability exercises in this population, since the differences between groups in the three variables are not statistically significant.

necessários à obtenção do grau de Mestre em Fisioterapia, área de especialização em
Fisioterapia em Condições Músculo-EsqueléticasINTRODUÇÃO: A disfunção do complexo articular do ombro (DCAO) ocorre em 8% a 20% das lesões no voleibol. A evidência sugere os efeitos de um programa de exercício escapulo-torácico (ET) em DCAO, com alteração na estabilidade dinâmica da omoplata, focados na ativação seletiva dos músculos estabilizadores locais (Trapézio Inferior – TI; Grande Dentado – GD) e redução da hiperatividade do Trapézio Superior (TS). O Biofeedback Eletromiográfico (BEMG) pode promover a ativação muscular seletiva dos músculos ET em sujeitos com DCAO, porém não existe investigação do seu efeito em overhead sports (OHS). OBJETIVO: Comparar os efeitos de um protocolo de exercícios ET com recurso ao BEMG comparativamente a um protocolo de exercícios ET ao nível da intensidade da dor, funcionalidade e intensidade de ativação muscular em atletas voleibolistas femininas com DCAO. METODOLOGIA: A amostra foi constituída por 14 atletas da equipa de voleibol feminina da Universidade Lusófona de Lisboa com DCAO, dividida em dois grupos (n=7 no Grupo Exercício – GEXC; n=7 no Grupo Exercício com recurso ao BEMG - GBEMG). Os dois grupos avaliaram-se em três momentos (T0 – avaliação inicial; T1 – avaliação às 4 semanas; T2 – avaliação às 8 semanas) na intensidade de ativação muscular (eletromiografia de superfície - EMGs) dos músculos TI, GD e TS em duas tarefas (lenta e balística), intensidade da dor (escala numérica da dor - END) e funcionalidade (DASH - Disabilities of the arm, shoulder and hand). Foi feita uma análise dos resultados das intervenções entre os dois grupos, em T1 e T2 e uma comparação dos resultados das intervenções em cada grupo, ao longo das três avaliações. RESULTADOS: Não se obtiveram quaisquer diferenças estatisticamente significativas (p>0.05) na avaliação entre os dois grupos nos três outcomes avaliados. Na tarefa lenta, o GEXC obteve diferenças estatisticamente significativas na intensidade de ativação no TS (p=0.028) e GD (p=0.028), entre T0 e T1, e no GBEMG, entre T1 e T2 na ativação no TI (p=0.028). Na tarefa balística, obtiveram-se diferenças significativas no GEXC entre T1 e T2 (no TS; p=0.028) e no GBEMG entre T0 e T2 (no TS; p=0.018). Para a intensidade da dor, obtiveram-se diferenças significativas no GEXC (T0-T2; p=0.024) e no GBEMG (T1-T2; p=0.026 / T0-T2; p=0.046). Para a Funcionalidade apenas o GBEMG obteve uma diferença significativa (T0-T2; p=0.028). DISCUSSÃO E CONCLUSÃO: O BEMG não apresentou efeitos adicionais significativos comparativamente ao exercício isolado.
INTRODUCTION: Disorders of the Shoulder Joint Complex (DSJC) account for an estimated 8% to 20% of all volleyball-related injuries. The literature describes the effects of scapula-focused exercises in DSJC with dynamic stability alterations, by selective activation of local stabilizing muscles (increase of lower trapezius – LT; serratus anterior - SA activation) and decrease of UT hyperactivity. Electromyographic biofeedback (EMGB) has been quoted as a way to improve selective muscle activation in subjects with DSJC, however there is no information about the effect of EMGB in overhead athletes. GOAL: To compare the effects of scapula-focused exercises using EMGB versus scapula-focused exercises focused on muscle activation, pain, and function, in female volleyball players with DSJC. METHODOLOGY: A sample of 14 individuals with DSJC (impingement syndrome and shoulder joint instability) was divided into two groups (n=7 – Exercise Group; n=7 – EMGB group). Both groups were evaluated in three moments (T0 – initial evaluation; T1 – after 4 weeks; T2 - after 8 weeks) regarding the intensity of muscle activity of UT, LT and SA (superficial electromyography - EMGs) during two upper limb functional tasks, pain (Numeric Pain Rating Scale - NPRS) and function (Disabilities of the arm, shoulder and hand – DASH). The data was analyzed, by a comparison of results between two groups followed by as analysis of the results in each individual group during the three evaluations. RESULTS: There were no statistically significant differences (p>0.05) of muscle activity between the two groups for the three outcomes. In regards to the slow activity, the Exercise Group had statistically significant differences in UT (p=0.028) and SA (T0-T1; p=0.028), and the EMGB had a significant difference in LT (T1-T2; p=0.028). The data for the ballistic activity revealed a significant difference in Exercise Group in UT (T1-T2; p=0.028), and the EMGB Group had a significant difference in UT (T0-T2; p=0.018). Pain reduced significantly in Exercise Group (T0-T2; p=0.024) and EMGB Group (T1-T2; p=0.026 / T0-T2; p=0.046). Function increased significantly only in EMGB Group (T0-T2; p=0.028). DISCUSSION AND CONCLUSION: The EMGB did not show any additional effects in muscle activity, pain, and function compared to isolated scapular exercises.

This Thesis aimed at studying the prevalence and severity and broadening the knowledge of aetiology and risk factors of groin injuries in male football. The four papers, which form part of this Thesis, are based on the same research project conducted on a cohort of amateur players from 17 Spanish teams. Variables such as information about groin pain in the previous season, pre-season short- and long-lever hip adductor squeeze strength, together with demographic and anthropometric data were collected at pre-season. Hip- and groin-related sporting function was registered at baseline, and every fourth week during the in-season, using the Sport and Recreation subscale from The Copenhagen Hip and Groin Outcome Score (HAGOS (Sport)) questionnaire. Time-loss groin injuries, registered by the team physiotherapist, in addition to self-reported groin pain, irrespective of time loss, were registered over 44 weeks to document all groin problems, and groin problems with and without time lossAquesta Tesi va tenir com a objectiu l'estudi de la prevalença i la severitat, i l’exemplar coneixement sobre l’etiologia i factors de risc de les lesions de l'engonal en futbolistes.

Background: Spiking is one of the most important scoring techniques in modern volleyball games. Eighty percent of shoulder pain in volleyball players are caused by spiking. In all volleyball injuries, players with shoulder pain lead to the longest time loss of practices and competitions. There are three risk factors for shoulder injuries in volleyball players: glenohumeral internal rotation deficit, scapula dyskinesis and the change of spiking biomechanics (kinematics and kinetics). Most of previous studies investigated static measurement and kinematic analysis of spiking movement in healthy athletes. There is no study examing shoulder kinematics during spiking movement in injured players. Purpose: The purpose of this study was to investigate the differences of glenohumeral joint, scapula, and trunk movements during spiking between volleyball players with and without shoulder pain. Materials and Methods: Twenty university volleyball league players with shoulder pain and 20 gender-age-experience matched control subjects were recruited in this study. All subjects undertook physical examinations such as, shoulder range of motion (ROM) and muscle strength tests. The kinematic measurement of upper extremity during spiking was carried out using an electromagnetic tracking system. The spiking tasks were performed in the laboratory setting. The volleyball was suspended on a wooden stick and the height of ball was chosen by each subject. The subject was asked to attack two target areas (40 cm × 40 cm) located 3 meters in front of the subject for five times. The study was approved by the ethical committee of National Yang-Ming University, Taipei (IRB number 1000091). Statistical analysis: The descriptive statistics were used to describe the basic data of all subjects and the two-way analysis of variance (2-way ANOVA) was used to analyze the difference of dependent variables between the experimental and the control group. The level of significance was set at α＝0.05. Results: Subjects with shoulder pain demonstrated less glenohumeral horizontal adduction angle at 2 events: at ball contact (P = 0.001) and at the occurrence of maximum glenohumeral external rotation (P = 0.039) as compared to the controls. Besides, subjects with shoulder pain demonstrated less scapular posterior tilting (P = 0.032) and less scapular upward rotation (P = 0.014) in the injured group at the moment of ball contact. Conclusion: Decrease in glenohumeral horizontal adduction and scapular posterior tilt and upward rotation were associated with shoulder pain in university volleyball players, which should be addressed in training and treatment of young volleyball players.

Mestrado em Ciências da FisioterapiaIntroduction The trunk plays an important role in tennis strokes. Its asymmetric muscle activation, coupled with the high repeatability of the sport, places tennis players at risk for injuries such as low back pain. Objectives This study aimed to present a trunk fatigue profile in tennis players and verify its association with low back pain (LBP). Material and Methods 35 tennis players completed an isometric trunk endurance protocol comprising four tasks, each one directed at a trunk muscle group (flexors, extensors and rotators). Low back Pain (LBP) history was obtained through the Nordic Musculoskeletal Questionnaire. Surface electromyography (EMG) activity was recorded bilaterally from rectus abdominis, external obliques and two portions of erector spinae. Average electromyographic amplitude (avrEMG) and median frequency (MF) values were determined for each muscle. Changes in both parameters over time, avrEMG average and MF slope were used as indicators of muscle activation and fatigue. Results and discussion A high prevalence of LBP was detected. Greater flexor and right EO endurance was observed in healthy subjects. LBP subjects showed less activation of the ES and dominant EO. This muscle’s degree of activation was also negatively correlated with LBP history. Healthy subjects had greater activity of the nondominant RA. Conclusion These results support the importance of increased activity of various trunk muscle activity in dynamic stability and the concept of load sharing in LBP subjects.
Introdução O tronco desempenha um papel importante na execução das pancadas no ténis. A activação muscular assimétrica, juntamente com a execução repetida destes gestos, coloca os tenistas em risco de desenvolver lesões como dor lombar (DL). Objectivos Este estudo teve como objectivo apresentar um perfil de fadiga muscular do tronco e a sua associação com queixas de dor lombar (DL). Material e métodos 35 tenistas completaram um protocolo de avaliação isométrico do tronco constituído por quatro tarefas dirigidas a diferentes grupos musculares (flexores, extensores e rotadores). A informação sobre antecedentes de DL foi obtida através do Questionário Musculoesquelético Nórdico. A actividade electromiográfica (EMG) foi recolhida bilateralmente no recto abdominal, oblíquo externo e duas porções dos extensores da coluna. Foram calculados os valores da amplitude electromiográfica média (avrEMG) e mediana da frequência (MF) para cada músculo. As alterações nestes parâmetros, o avrEMG médio e o declive da MF foram usados como indicadores da activação e fadiga musculares. Resultados e discussão Foi registada uma elevada prevalência de DL. Os sujeitos sem DL registaram uma maior resistência nos testes dos flexores e ponte lateral direita. Os sujeitos com DL mostraram uma menor activação da musculatura extensora e do oblíquo externo dominante. O grau de activação deste músculo mostrou uma correlação negativa com a presença de DL. Foi registada uma maior actividade do RA não dominante em sujeitos saudáveis. Conclusão Estes resultados apoiam a importância da activação dos vários grupos musculares do tronco para a estabilidade dinâmica da coluna e o conceito do load sharing em sujeitos com DL.

Background and Purpose: Patellofemoral pain syndrome (PFPS) is a common musculoskeletal disorder on athletes. The etiology was feathering multi-factorial. Femur internal rotation was proved to contribute in patella lateral laterization position in patients with PFPS. Excessive hip adduction and internal rotation during various tasks were recognized in patients with PFPS and associated with the increased stress of patellofemoral joint. Therefore, hip movement control can be an important issue when making management decision. Hip stabilization brace was proved to be effective in pain reduction, decreasing hip internal rotation and improving posture stability. Kinesio taping has been applied in the upper extremity for movement correction. However, whether applying Kinesio taping is able to correct the movement patterns of the lower extremity during weight bearing activities remains unknown. Therefore, the purpose of this study was to investigate the immediate effects of hip corrective taping on hip and knee movements during lay-up jump and single-leg squat in basketball players with PFPS. Methods: 12 basketball players (10 males, 2 females) with PFPS and 14 healthy (10 males, 4 females) player were asked to perform lay-up jump and single-leg squat with and without corrective taping. Whole body kinematics and ground reaction forces were recorded using Vicon 3D motion analysis system (200Hz) and an AMTI force plate (1000Hz). The primary objectives of corrective taping in this study were to limit hip adduction and internal rotation and provide guidance of hip abduction and external rotation during tasks. Thus, kinesio tape was applied from 3 cm below medial tibia epicondyle to 3 cm above ipsilateral anterior superior iliac crest spirally with maximal tension. Results: The PFPS group showed greater knee external rotation than healthy players (10.23° v.s. 4.88°) but no significant differences in hip joint kinematic during lay-up jump. However, distance between center of mass and hip joint center in PFPS group was shorter than control group. In terms of taping effects, for lay-up jump task at initial contact, the angle of knee external rotation was significantly decreased after taping. (10.24° vs. 8.02°, p = 0.038). For single-leg squat task, hip internal rotation was significantly decreased (7.94° vs. 4.72°, p = 0.050). A trend of decreased hip adduction were also observed (11.45° vs. 10.16°, p = 0.059). Conclusions: Corrective taping applied in this study may have the effects of decreasing hip adduction and internal rotation in basketball players with PFPS during both static and dynamic tasks. Clinical Relevance: The results of current study provided evidence for corrective taping in basketball players with PFPS to limit hip movement patterns associated with increased patellofemoral joint stress. Clinically this taping method may be beneficial for the other populations with PFPS.

Full textAbstract:
This study examines how females with distinct life histories and social
backgrounds (but shared experiences as competitive athletes) interpret sport-related pain,
risk, and injury. The research was guided by the following research questions: What
kind of perspectives do competitive female soccer players have toward pain, risk and
injury? Are differences in sport-related socialization related to different social
experiences with and/or understandings of pain and injury? Are varying types and
strengths of social support networks related to different kinds of pain and injury
expression, or different social experiences of pain and injury?
An oral narrative approach (Reissman, 1993) was used to interview twelve female
competitive soccer players from Vancouver area soccer teams who had sustained a
relatively severe or debilitating injury. Each athlete was asked to participate in two
interviews. These athletes were asked (a) about their injury "story;" (b) about their early
and continual socialization into the sport; and (c) to identify and describe the role of
influential figures throughout their sporting participation.
In general, athletes used a combination of narrative styles when describing their
injury experience—with the most prominent and pervasive being a "restoration to health
and fitness" narrative. Other prominent narratives included a "hopelessness" narrative
(within which athletes expressed their frustration and lack of control over the injury), and
a "hope" narrative (within which athletes spoke of becoming more aware of their bodies
and their limitations through the experience of injury). Interviewed athletes also
described how the injury led to a disruption of their identity/self, and how they developed
new perspectives on risk-taking because of their injury experience. Also, athletes
suggested a practical application of a "pain club" (or support group) for similarly injured
competitive athletes.
These findings have theoretical implications for understanding how athletes make
sense of their bodies and their injuries, and practical implications for how injuries may be
attenuated and more thoroughly addressed. These findings also speak to the power of
socialization into a competitive sport culture, resulting in a deep submersion within an
athletic identity for these athletes.Education, Faculty of

Full textAbstract:
This thesis explores potential risk factors for low back pain in elite adolescent tennis
players. Low back pain (LBP) is one of the most significant causes for loss of playing
time in elite junior tennis players and can result in up to 4-5 months away from
competition. Current research has explored lumbar spine abnormalities as well as serve
and groundstroke biomechanics in tennis in an attempt to better understand the
manifestation of LBP in the sport. However, the vast majority of this research has been
cross-sectional and limited to male playing populations, meaning that the mechanisms of
LBP remain unclear. To address the lack of knowledge on the mechanisms of LBP and to
provide improved evidence-based prevention for players, this course of studies
investigated multiple proposed causes for LBP; including lumbar spine abnormalities,
serving biomechanics and workload in a sample of elite adolescent tennis players over a
12-month period.
During this study, 19/25 players presented with lumbar spine abnormalities. The most
common abnormalities were disc degeneration, pars abnormalities (including bone
marrow oedema (BMO)) and facet joint degeneration. Interestingly, the presence of BMO
did not influence LBP, with only 3/12 players who presented with BMO experiencing
LBP. Further the severity of BMO did not appear associated with LBP, which is contrary
to the findings in other sports such as cricket. Lastly, the link between pars abnormalities
and facet joint orientation still remains unclear due to contradicting results at baseline and
follow-up.
The biomechanics of the adolescent serve, specifically peak leg, trunk and racquet
kinematics and kinetics, were not related to the presence of pars abnormalities. However,
there was evidence to suggest that the timing of these peak mechanics are. Players with
pars abnormalities entered peak right knee flexion and peak lumbar right lateral flexion
earlier than those without pars abnormalities. Also, the players with pars abnormalities
entered the trophy position (racquet high point) and experienced peak lumbar posterior
force later than those without pars abnormalities. Therefore, this provides cause for
coaches to reconsider the importance of the timing of the tennis serve in the context of
pars abnormalities and potentially LBP.
Lastly, when referring to players who experienced LBP in this cohort, all players had a
spike in workload with an acute chronic workload ratio (ACWR) ≥1.5. Previous research
has flagged this ratio as a risk factor for LBP, yet the high frequency of these spikes in
adolescent tennis players complicates their direct link with LBP.
It is difficult to conclude the specific causes for LBP in elite junior tennis players. This
thesis reveals that BMO is not linked to LBP as many players with diagnosed BMO
remained pain-free. The order in which players perform key serving events (for example
racquet high point) do appear related to the presence of pars abnormalities and potentially
LBP. Lastly, the relationship between workload and LBP remains unclear and warrants
further investigation. Overall, this thesis contributes to the small but growing research
into LBP among tennis players and progressively increases our understanding of LBP
risk factors.

MSc, Physiotherapy, Faculty of Health Sciences, University of the WitwatersrandIntroduction Disabled sport has become very popular over the last decade with a variety of sports now available for persons with disabilities to compete in. Wheelchair basketball is a fast growing sport in South Africa. However, it is also considered a high-risk sport with most reported injuries coming from participating in the game along with tennis, road racing, rugby and soccer (Nunome et al, 2002, Ferrara and Peterson, 2000 and Curtis, 1997). The sport is characterised by high intensity propulsion and manoeuvring as well as reaching overhead for shooting, passing and rebounding (Goosey-Tolfrey et al, 2002 and Curtis et al, 1999). The athletes are thus at risk of developing in particular shoulder injuries. This study aimed to establish the prevalence of shoulder pain in South African; Gauteng based professional male wheelchair basketball players. It aimed to highlight predisposing factors contributing to the prevalence of shoulder pain as well as establish whether there is a difference in shoulder pain between the wheelchair bound athletes vs. the otherwise ambulatory athletes. By quantifying the magnitude of the problem it was hoped that awareness would lead to measures taken to rectify any problems highlighted by the research. Methods Twenty-nine professional South African: Gauteng male wheelchair basketball players took part in a cross sectional descriptive survey based study. The researcher, following signed informed consent, administered a piloted valid and reliable questionnaire to gain information regarding demographics, medical history and lifestyle habits. Results were expressed in the form of tables and graphs with frequencies, percentages and averages used to describe findings. Results Prevalence of shoulder pain was found to be 72.4% with 21 of 29 participants having experienced shoulder pain since using a wheelchair and 11 of the 29 (37.9%) having current shoulder pain. The number of years using a wheelchair significantly influenced the prevalence iv of shoulder pain (p = 0.03). One hundred percent (nine out of nine) of participants who had been using a wheelchair for longer than 10 years had experienced the problem, while of those who had been using a wheelchair for less than 10 years, 57.14% (four out of seven) had experienced shoulder pain. Time spent at work was found to be significantly associated with the presence of shoulder pain. Of the 12 people who worked more than 30 hours per week, 12 (100%) had experienced shoulder pain (p = 0.05). In the comparison of the ambulatory vs non ambulatory athletes, the wheelchair bound participants tended to be more likely to experience shoulder pain with 12 out of 15 having shoulder problems and 7 of the 12 ambulatory participants having experienced shoulder pain. This was however not a significant finding (p = 0.22). Conclusion It was found that the prevalence of shoulder pain in professional wheelchair basketball athletes in Gauteng was 72.4%. This was significantly associated with hours spent at work as well as years spent using a wheelchair. There were no significant findings regarding shoulder pain prevalence in the otherwise ambulatory vs wheelchair bound wheelchair basketball athletes. Shoulder pain is an important problem in the wheelchair basketball athlete. More education is needed regarding prevention of shoulder problems in our athletes with an emphasis on posture and ergonomic handling.

Background and purpose Medial elbow injuries are common in youth baseball players. Repetitive throwing movement places excessive valgus stress over the immature elbow that may cause medial elbow injury. Previous studies have investigated the relationships between throwing kinematics and elbow valgus stress in healthy adult throwers. No research compares the differences in throwing kinematics and physical characteristics between youth baseball players with and without medial elbow pain. The purpose of this study was to investigate throwing kinematics and physical characteristics (muscle strength, flexibility and balance) in youth baseball players with and without medial elbow pain. Methods Fifteen players with previous medial elbow pain and 15 healthy players participated in this study. Age, height, and weight were matched for the two groups. Throwing kinematics were recorded by an electromagnetic motion analysis system. Foot switch was used for determining foot off and foot strike. Ball speed was recorded with a sports radar gun. Isometric strength of trunk, hip, and shoulder was measured using a torque sensor attached to a custom device. Elbow, shoulder, and hip flexibility were measured with a goniometer and a tape measure. Single leg standing balance with eyes open and eyes closed was assessed with a force plate. Paired-t tests were used to compare the differences in throwing kinematics, muscle strength, flexibility, and single leg standing balance between the two groups. Results Elbow pain group demonstrated less elbow flexion angle at maximum shoulder external rotation in late cocking phase and had more trunk lateral tilt at ball release compared to the healthy group. No significant differences were found in isometric strength of trunk, hip, and shoulder between the two groups. Elbow pain group had less passive range of motion in shoulder external rotation compared to the healthy group. In the elbow pain group, elbow flexion angle and total elbow range of motion were less in the throwing arm compared to the non-throwing arm. Less flexibility was observed in the lead hip compared to the non-lead hip in the elbow pain group. There were no significant differences in single leg standing balance between the two groups. Conclusions Differences in throwing kinematics and flexibility were found between youth baseball players with and without previous medial elbow pain. Clinicians and baseball coaches should pay attention to these risk factors in addition to their age, height, weight, and overuse for protecting these players.

This study was designed to execute a body-mind movement education programs, based on the theory of Somatics, for the Judo players with shoulder joint pain. In order to research the effect of these programs before and after implementation, the study focused on the degree of pain reducing in shoulder joint, self-awareness and differences of physical and mental experience. This study applied both quantitative experimental method and supplemented by qualitative analysis to A Judo team with shoulder injuries players, in a National High School. There were 10 males and 10 females divided into control group without any intervention and the experimental group with implementation of a 10-week somatic movement education programs. Those subjects were separated evenly 5 boys and 5 girls for each group. Both groups accepted the test of joint activity, shoulder joint pain index, over shoulder throw action assessment, body awareness ability scale, and covariance analysis to test the experimental group and control group differences. It was to learn how somatic movement education courses could affect their body uses and the changes of sensation in Judo players with shoulder joint pain. By applying qualitative analysis to understand if Judo players accept the somatic movement education courses and what they have learned after class. Research findings included: 1.The somatic movement education had positive effects on the junior high school Judo players’ shoulder joint range of motion: Players had significant improvement in “flexion”, “extension”, “abduction”, “external rotation”, and “internal rotation” after receiving the somatic movement education (p＜.05). 2.The somatic movement education effectively reduced the shoulder joint pain of the junior high school Judo players: Results showed that players in the experimental group experienced a significant decline of their “shoulder joint pain index” (p＜.05) after receiving the 10-week courses. 3.The somatic movement education had significant effects on the completeness of Judo players: Players in the experimental group showed significant improvement in their over shoulder throw accuracy, coordination, and the ability to complete all the phases of step moving, waist twisting, hand action, and shift of center of gravity (p＜.05). 4.Somatic movement education programs significantly enhanced the effect on the perceived ability of the body for Judo players (p＜.05). 5.The learning attitude of Judo players were positive and they were interested in what they were learning during the class.

Background: Lumbar segmental instability and iliopsoas tightness are recognized as contributing factors to identifiable subgroups of individuals among the heterogeneous LBP conditions. The lumbar segmental instability might be caused by the iliopsoas tightness that aggravated lumbar lordosis, indirectly resulting in low back pain, decreased muscle strength or flexibility around pelvic region, and over activities of lumbar muscles during lumbar flexion. In addition, high prevalence of iliopsoas tightness and back pain has been reported in football players. However, direct link between iliopsoas tightness and lumbar instability is still lacking. In addition, no studies have investigated the effects of core stability training in football players with iliopsoas related back pain, especially focusing on the improvement of sports performance. Purpose: This study aimed to investigate the effects of the core stabilization exercise (CSE) on sports performance in football players with or without iliopsoas tightness. The effect of additional myo-facial release techniques was also examined. Methods: Twenty-two high school football players were divided into 4 different groups, 7 with instability and iliopsoas tightness (LI-IT), 4 with iliopsoas tightness (nonLI-IT) and 4 with instability (LI-nonIT) with chronic low back pain, and 7 non-symptomatic controls, were recruited based on physical assessments and clinical tests in the beginning. All subjects participated in CSE training for 10 weeks. Subjects with iliopsoas muscle tightness (IT) were then arranged to take 4 additional weeks of myofascial release (MR) treatments and regular football training after completing post-CSE assessment. Meanwhile, subjects without iliopsoas muscle tightness (non-IT) and the 7 control subjects only took regular football training. A series of physical assessments focusing on the assessment of pain status, the flexibility and strength tests for trunk and hip muscles , muscle activation patterns for back extensors during prone hip extension and standing lumbar flexion movements, and sports performances were arranged at different stage points, including the initial assessments (Initial),the assessments two months (the control phase) prior to CSE (pre-CSE ), the assessments post CSE (post-CSE), and the 4th assessments after completing MR treatments(post-MR). Results: No significant differences were found between the first two assessments before and after the control phase for all sub-groups. After completing 10 weeks CSE training, significant improvements were only found in the LI-nonIT group, including the proportion of lumbar instability, pain intensity, paravertebral muscle activities at full lumbar flexion and the reversed phase, the flexibility of hip rotators and the strength of hip and trunk flexors and extensors, and sports performances. (p〈0.05). However, after completing the MR treatment, the groups with IT also exhibited significant improvement in the proportion of lumbar instability, pain intensity, paravertebral muscle activities at full lumbar flexion and the reversed phase, the flexibility of hip rotators and the strength of hip and trunk flexors and extensors, and sports performances. (p〈0.05). Conclusion: This study has confirmed the effect of CSE training for the football players with LI but without iliopsoas tightness. However, significant improvements were not found in subjects with iliopsoas tightness until completing additional MR treatment. The results have suggested a priority of treating iliopsoas tightness before CSE training is conducted for the young athletes with iliopsoas related back pain. These results might clearly imply the importance of iliopsoas associated with active system of lumbar stability in the treating young athletes with lower crossed syndrome. In conclusion, this study was the first research to provide evidence for supporting the effects of CSE training and MR treatment on iliopsoas for athletes with iliopsoas related back pain in reducing pain, improving lumbar stability, and especially promoting sports performances. Iliopsoas release treatment should be used as a routine maneuver prior to core stability training in treating young athletes that have non-specific backache accompanied with iliopsoas tightness or lumbar segmental instability.

Background: Low back pain (LBP) is a common complaint in baseball players and often compromise their performance such as pitching or throwing. Overarm throwing, one of the basic skills in baseball pitching and fielding, requires the trunk to transfer energy and generate force to complete the kinetic chain of the activity. Previous studies revealed that patients with back pain showed deficits in trunk mobility, , movement velocity and coordination. However, no studies have been done to examine if low back pain affects the trunk kinematics in baseball overarm throwing in similar patterns as the general population.. Purpose: The purpose of this investigation was to explore the association of low back pain on the pelvic, trunk, and shoulder kinematic and temporal parameters in baseball overarm throwing. Methods: This study is a cross-sectional design. The subject performs 10 overarm fast balls with maximum speed from a simulated in-door pitching mount. Kinematic and temporal parameters during different phases of overarm throwing were collected with 10 high-speed Eagle Camera system and differences were compared between baseball players with and without low back pain. Statistical Analysis: The effect size (Cohen’s d) was calculated to compare differences of the basic data, the kinematic and temporal parameters between the two groups during each phase of throwing. Results: Players with LBP exhibited faster ball velocity than the non-LBP players. They also showed delay rotation of trunk during early stage of throwing, increased trunk forward tilt angle at ball release, faster trunk rotation velocity and slower pelvis rotation velocity during arm acceleration, decrease shoulder abduction at shoulder maximum external rotation. If adding the information of shoulder pain, those who had both low back and shoulder pain rotated trunk ealier so that it was in a close orientation during arm cocking and arm acceleration phases, then they delayed the rotation of the pelvis but increased the trunk forward tilt angle at ball release. Also, they reached shoulder max external rotation and horizontal adduction much faster than the non-LBP counterparts.. Discussion and Conclusion: Baseball player with low back pain differed in the pelvic, trunk, and shoulder kinematic and temporal parameters during different phases of overarm throwing as compared to those without low back pain. The results indicated that LBP player adopted a compensatory strategy of reducing trunk rotation and increasing trunk forward tilt angle at ball release during overarm throwing. This compensatory strategy might be a result of protection painful segment by decrease trunk rotation, but the increase of forward tilt angle to increase ball speed could further add stresses to the lower back area in these players. This study was the first to show distinct differences in overarm throwing between players with and without low back pain and provided valuable guidance for clinicians and coaches to improve technique to facilitate recovery from overarm-related low back pain.

Full textAbstract:
Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Department of Chiropractic, Durban University of Technology, Durban, South Africa, 2016.Background There has been a remarkable increase in the participation of sport for athletes with disabilities. Consequently, there have been many international studies on injuries in athletes which have shown a high prevalence in wheelchair basketball, largely attributed to the fast-paced, high intensity nature of the sport. This sport has grown worldwide including South Africa, however, very little research has been published on South African wheelchair basketball players and more research is, therefore, needed. Aim To determine the prevalence and profile of musculoskeletal pain in elite wheelchair basketball players of different point classifications in South Africa. Hypothesis 1: Upper extremity (including neck and back) pain is experienced more commonly in lower point classified wheelchair basketball players than in higher point classified players. Hypothesis 2: Lower extremity pain is experienced more commonly in higher point classified players than in lower point classified players Method This study was a quantitative, cross-sectional, questionnaire-based study. The questionnaire comprised of sub-sections on demographics and disability characteristics; activity levels pertaining to wheelchair basketball and other sport/physical activity; the prevalence of pain and the impact thereof on wheelchair basketball and/or activities of daily living. This questionnaire was administered to 48 wheelchair basketball players who were competing in the 2015 Supersport League. A response rate of 70% was decided as the lower limit cut-off for statistical power. Results Fourty-three participants responded yielding an 89.58% response rate. The mean age of participants was 33.3 (SD:9.5) years and the majority of participants (n=35) were male and African (n=29). Out of the 43 participants, 79.1% (n=34) used mobility devices, the majority (n=20) used wheelchairs. Most of the participants (n=41) played wheelchair basketball for more than five years and 32 participants did not participate in other sport. Almost half of the participants (n=25) experienced musculoskeletal pain in the last twelve months or at present, 75% of whom (n=12) visited a Physiotherapist for the pain. More than half of these participants (n=15; 60%) reported that the pain negatively affected their basketball performance. It was established that arm pain occurred frequently in lower point classified players (1.0-2.5 point players) and that hand and wrist pain was also more prevalent in lower point players than in higher point players. The prevalence of lower extremity pain was low and there was no statistically significant difference between higher and lower point classified players. Conclusions and Recommendations The finding that upper extremity pain occurred more frequently in lower point classified players was in keeping with the first hypothesis (the null hypothesis was, therefore, rejected). The second hypothesis was, however, rejected (and the null hypothesis was, therefore, accepted) as lower extremity pain did not occur more frequently in higher point classified players than in lower point classified players. The Eta scores may have been higher and may have shown a much larger than typical relationship between point classification and the prevalence of musculoskeletal pain had there been a larger sample size. Notwithstanding this limitation, it is a challenge to obtain a significantly larger sample size due to the nature and limited number of participants in this sport. More studies are warranted on this group of individuals, as a large number experienced pain which affected more than half of the participants’ performance in wheelchair basketball. These studies are important for the future success of the South African players and the sport in South Africa.

Full textAbstract:
Neuropathic pain, caused by neuronal damage, is a severely impairing mostly chronic condition. Its underlying molecular mechanisms have not yet been thoroughly understood in their variety. In this doctoral thesis, I investigated the role of microRNAs (miRNAs) in a murine model of peripheral neuropathic pain. MiRNAs are small, non-coding RNAs known to play a crucial role in post-transcriptional gene regulation, mainly in cell proliferation and differentiation. Initially, expression patterns in affected dorsal root ganglia (DRG) at different time points after setting a peripheral nerve lesion were studied. DRG showed an increasingly differential expression pattern over the course of one week. Interestingly, a similar effect, albeit to a smaller extent, was observed in corresponding contralateral ganglia. Five miRNA (miR-124, miR-137, miR-183, miR-27b, and miR-505) were further analysed. qPCR, in situ hybridization, and bioinformatical analysis point towards a role for miR-137 and -183 in neuropathic pain as both were downregulated. Furthermore, miR-137 is shown to be specific for non-peptidergic non-myelinated nociceptors (C fibres) in DRG. As the ganglia consist of highly heterocellular tissue, I also developed a neuron-specific approach. Primarily damaged neurons were separated from intact adjacent neurons using fluorescence-activated cell-sorting and their gene expression pattern was analysed using a microarray. Thereby, not only were information obtained about mRNA expression in both groups but, by bioinformatical tools, also inferences on miRNA involvement. The general expression pattern was consistent with previous findings. Still, several genes were found differentially expressed that had not been described in this context before. Among these are corticoliberin or cation-regulating proteins like Otopetrin1. Bioinformatical data conformed, in part, to results from whole DRG, e.g. they implied a down-regulation of miR-124, -137, and -183. However, these results were not significant. In summary, I found that a) miRNA expression in DRG is influenced by nerve lesions typical of neuropathic pain and that b) these changes develop simultaneously to over-expression of galanin, a marker for neuronal damage. Furthermore, several miRNAs (miR-183, -137) exhibit distinct expression patterns in whole-DRG as well as in neuron-specific approaches. Therefore, further investigation of their possible role in initiation and maintenance of neuropathic pain seems promising. Finally, the differential expression of genes like Corticoliberin or Otopetrin 1, previously not described in neuropathic pain, has already resulted in follow-up projectsNeuropathischer Schmerz, d.h. Schmerz durch neuronale Schäden, ist eine stark beeinträchtigendes, oft chronisches Leiden. Die hierfür verantwortlichen molekularen Geschehen sind in ihrer Breite bislang nur unzureichend verstanden. In meiner Promotion habe ich die Rolle von microRNAs (miRNAs) in einem Mäusemodell des peripheren neuropathischen Schmerzes untersucht. MiRNAs sind kleine, nicht kodierende RNAs, die für posttranskriptionelle Genregulation, besonders Zellproliferation und –differenzierung verantwortlich sind. Im Experiment wurde zunächst ihre Expression in den Dorsalganglien geschädigter Nerven analysiert. Hier zeigte sich im Verlauf einer Woche ein zunehmend differentielles Expressionsmuster. Bemerkenswert war ein ähnlicher, wenn auch geringerer Effekt in kontralateralen Ganglien. In einem weiteren Schritt wurden fünf ausgewählte miRNAs (miR-124, miR-137, miR-183, miR-27b und miR-505) weiter analysiert. qPCR, In-situ-Hybridisierung und bioinformatische Untersuchungen deuteten auf Minderexpression von miR-137 und -183 bei neuropathischem Schmerz hin. Weiterhin stellte sich miR-137 als spezifisch für nicht-peptiderge nicht-myelinisierte Nozizeptoren in Dorsalganglien heraus. Da Dorsalganglien aus äußerst heterozellulärem Gewebe bestehen, entwickelte ich im Folgenden einen neuronenspezifischen Ansatz: Primär geschädigte sowie intakte benachbarte Neuronen wurden durch fluoreszenz¬aktivierte Zellsortierung (FACS) selektiert und ihre Genexpression jeweils in einem Microarray analysiert. Hierdurch konnten nicht nur direkte Informationen über mRNA-Expression in beiden Gruppen gewonnen, sondern durch bioinformatische Techniken auch Rückschlüsse auf miRNA-Expression gezogen werden. Das generelle Expressionsmuster entsprach der einschlägigen Literatur, allerdings zeigten sich auch bislang nicht beschriebene Veränderungen. Hierzu gehören Corticoliberin sowie Otopetrin1. Die bioinformatische Analyse bestätigte teilweise die Ergebnisse aus der ersten, ganglienweiten Untersuchung: Sie wiesen auf eine Minderexpression von miR-124, -137 und -183 hin, allerdings waren diese Ergebnisse nicht signifikant. Zusammengefasst zeigte sich, dass sich a) die Expression von miRNA in Dorsalganglien nach neuropathischen Läsionen ändert, und b) diese Veränderungen parallel zum neuropathischen Phänotyp entwickeln. Weiterhin wiesen mehrere miRNAs markante Expressionsmuster sowohl in ganglienweiten wie in neuronenspezifischen Untersuchugen auf. Daher scheint die weitere Untersuchung ihrer Rolle in Entwicklung und Aufrechterhaltung von neuropathischem Schmerz vielversprechend. Schließlich hat die Entdeckung von Expressionsveränderungen bei Genen wie Corticoliberin und Otopetrin1, bislang nicht im Zusammenhang mit neuropathischem Schmerz beschrieben, bereits zu Nachfolgeprojekten geführt

Background: Medial elbow pain (MEP) is a common problem that could affect the performance of adolescent baseball players. During pitching motion, about 48 N-m elbow valgus torque is generated at the late cocking phase to the acceleration phase in adolescent baseball players. Cumulative microtrauma through the repetitive throwing motion may result in elbow injuries. To avoid the medial compartment being overstretched, maximum elbow varus torque is produced by the interaction moment resulting from shoulder internal rotation. Although increased shoulder external rotation (ER) and decreased shoulder internal rotation (IR) were found in most baseball players, the relationships between the MEP and shoulder range of motion (ROM), soft tissue tightness, rotator strength and alignment have not been rigorously investigated in the literature. Purposes of the study: To determine the relationships among the MEP and shoulder ROM, soft tissue tightness, rotator strength and alignment in adolescent baseball players. Study design: A cross-sectional study. Methods: Twenty-eight adolescent baseball players with MEP (elbow pain group) for at least 1 week and twenty-eight adolescent baseball players without MEP (comparison group) were recruited in this study. Active ROM of shoulder IR and ER of both arms of the subjects were measured. Soft tissue tightness was measured by the ROM of shoulder horizontal adduction. Humeral retroversion assessment was assessed by X-ray film to calculate the humeral retroversion angle. Statistical analysis: Means and standard deviations of active ROM of shoulder IR and ER were calculated. Independent t tests were used to compare the differences of active ROM shoulder IR and ER between the groups with and without MEP. Independent t tests were also used to compare the differences of shoulder IR and ER strength between the groups with and without MEP. Pearson correlation coefficients were calculated to determine the relationships between the range of shoulder horizontal adduction and the ranges of shoulder rotation. Pearson correlation coefficients were also calculated to determine the relationships between the ranges of shoulder rotation and the humeral retroversion angle. A statistical significance was set as p < 0.05. Results: Significant differences were found between the elbow pain group and the comparison group in the range of shoulder IR, elbow flexion ROM, strength of shoulder ER and IR. Significantly negative correlations were found between shoulder IR and horizontal adduction as well as positive correlations between shoulder ER and horizontal adduction. Conclusion: Adolescent baseball players with MEP demonstrated less shoulder IR mobility and decreased shoulder rotator strength than baseball players without pain. One reason for explaining the decreased IR mobility may be related to shoulder instability which could cause increased elbow valgus torque during throwing and result in elbow pain.

Dissertation submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic at the Durban University of Technology, 2009Objectives: When we consider the body position of a field hockey player, the lumbar spine is always in a flexed position, which combined with rotational movements during various hitting and pushing techniques, increases the strain upon the spine and surrounding muscles, thus leading to low back pain. To determine the relationship between core strength and trunk extensor endurance relating to the incidence of acute low back pain in field hockey players. Project Design: The research project was in the form of a quantitative cross-sectional study, using human subjects. Setting: The research project occurred during the field hockey season (2008) with players who had acute low back pain. The players were clinically assessed and subdivided into necessary groups at the Chiropractic Day Clinic at the Durban Institute of Technology. Subjects: Adult, male patients, aged between 18 and 30 years of age, playing premier field hockey. Out of the thirty players, 12 players have played in the National u/21 squad, 7 players have played in a Junior National team and 11 players have played senior provincial field hockey. Outcome measure: This included three tests. Firstly, the absolute difference of pressure from the reference value of 70mmHg (prone) and 40mmHg (supine) was used as the outcome measure on a Pressure Biofeedback Unit and length of time (in seconds), a correct contraction of the core stability muscles was maintained. Secondly, the length of time (in seconds) for Trunk Extensor Endurance. Thirdly, repeated measures for NRS-101 and Quebec Back Pain Disability Scale for the duration of the research period. v Results: It was found that there was no statistical evidence or convincing trend to show that the training programmes (core stability and trunk extensor endurance) increased the subjects’ core strength or trunk extensor endurance in the time allocated, although there seemed to be a placebo effect in the Trunk Extensor Group, which showed improvement in some of the core stability outcomes. There was statistical evidence that the intervention (training programmes) reduced pain, according to the Quebec Back Pain Disability Scale (Quebec) score over time, and a non-significant trend suggested this according to the Numerical Rating Scale-101 (NRS). Since both groups’ NRS and Quebec scores were not significantly different at baseline, the difference can be attributed to the effect of the intervention. Conclusions: The results of this study found that the Trunk Extensor Endurance Group, that performed the trunk extensor endurance training programme, yielded better results in core stability and trunk extensor endurance. However, the Core Stability Group, that performed the core stability training programme, showed a quicker reduction in pain levels during the three week intervention period. Therefore, by combining both training programmes, future rehabilitation of athletes suffering from acute low back pain will be more successful. Sport performance of the athletes (field hockey players), through the proponents of swiss ball training, will also improve.

22, xii, 44 leaves, Appendices 1-10Lower back pain and lower back injuries have been documented as one of the most common musculoskeletal problems in both amateur and professional tennis players. It has also been documented that the serve, which may be considered one of the most important strokes of the game, is also the most likely stroke to cause back pain. A good tennis serve requires considerable trunk rotation. The serve is the highest stress strain action during tennis. In a two set game the minimum number of serves a player may hit is 24 with a maximum excluding deuces and advantages of 96. The “Topspin serve” in particular requires the player to arch their back and this puts the lumbar spine into hyperextension. These movements thus put considerable pressure on the facet joints and multifidi muscles. It stands to reason that any joint related clinical entity can change biomechanics and affect the serve. In research done on golfers with mechanical lower back pain, it was found that club head velocity as well as pain decreased in symptomatic golfers with mechanical lower back pain after manipulation (Jermyn, 2004). No research has yet been done on manipulation of tennis players with lower back pain. The aim of this investigation was to determine the immediate effect of a lumbar manipulation on the clinical and performance measures of amateur tennis players suffering from lower back discomfort associated with playing tennis.
