In experiments investigating vertical squat jumping, the HAT segment is typically defined as a line drawn from the hip to some point proximally on the upper body (eg, the neck, the acromion), and the hip joint as the angle between this line and the upper legs (θUL-HAT). In reality, the hip joint is the angle between the pelvis and the upper legs (θUL-pelvis). This study aimed to estimate to what extent hip joint definition affects hip joint work in maximal squat jumping. Moreover, the initial pelvic tilt was manipulated to maximize the difference in hip joint work as a function of hip joint definition. Twenty-two male athletes performed maximum effort squat jumps in three different initial pelvic tilt conditions: backward (pelvisB), neutral (pelvisN), and forward (pelvisF). Hip joint work was calculated by integrating the hip net joint torque with respect to θUL-HAT(WUL-HAT) or with respect to θUL-pelvis(WUL-pelvis). θUL-HATwas greater than θUL-pelvisin all conditions. WUL-HAToverestimated WUL-pelvisby 33%, 39%, and 49% in conditions pelvisF, pelvisN, and pelvisB, respectively. It was concluded that θUL-pelvisshould be measured when the mechanical output of hip extensor muscles is estimated.

Change from quadruped to erect posture has resulted in changes in the human pelvis. This has resulted in pelvis supporting the abdominal viscera. The bony pelvis is deficient on inferior aspect. Muscles covered by fascia on superior and inferior aspect. A good knowledge of pelvic floor is very basic and mandatory for any gynecologist as pelvic floor is crucial to support the pelvic organs and is required to maintain urinary and fecal continence.

The pelvis of crocodilians is highly derived in that the pubic bones are isolated from the acetabulum and are attached to the ischia via moveable joints. We examined the possible role of this unusual morphology in lung ventilation by measuring ventilation, abdominal pressure and the electrical activity of several abdominal and pelvic muscles in the American alligator (Alligator mississippiensis). We found that the activity of two pelvic muscles, the ischiopubis and ischiotruncus muscles, was correlated with inspiration; these muscles rotate the pubes ventrally and thereby increase abdominal volume. During expiration, contraction of the rectus abdominis and transversus abdominis rotates the pubes dorsally. We suggest that this mechanism facilitates diaphragmatic breathing by creating space for caudal displacement of the viscera during inspiration. Because birds also use a dorso-ventral movement of the pelvis to effect ventilation, some form of pelvic aspiration may be plesiomorphic for archosaurs.

Background. Strengthening of hip and trunk muscles can modify pelvis and hip movements. However, the varus alignment of the foot-ankle complex (FAC) may influence the effects of muscle strengthening, due to the relationship of FAC alignment with pelvic and hip kinematics. This study evaluated the effects of hip and trunk muscle strengthening on pelvis and hip kinematics during walking, in subgroups with larger and smaller values of FAC varus alignment. In addition, this study evaluated the effects of hip and trunk muscle strengthening on hip passive and active properties, in the same subgroups. Methods. Fifty-three women, who were divided into intervention and control groups, participated in this nonrandomized controlled trial. Each group was split into two subgroups with larger and smaller values of FAC varus alignment. Hip and trunk muscle strengthening was performed three times a week for two months, with a load of 70% to 80% of one repetition maximum. Before and after strengthening, we evaluated (1) pelvis and hip excursions in the frontal and transverse planes during walking, (2) isokinetic hip passive external rotator torque, and (3) isokinetic concentric and eccentric peak torques of the hip external rotator muscles. Mixed analyses of variance (ANOVAs) were carried out for each dependent variable related to walking kinematics and isokinetic measurements (α=0.05). Results. The subgroup with smaller varus alignment, of the intervention group, presented a reduction in pelvic drop after strengthening (P=0.03). The subgroup with larger varus alignment increased pelvic drop after strengthening, with a marginal significance (P=0.06). The other kinematic excursions did not change (pelvic anterior rotation P=0.30, hip internal rotation P=0.54, and hip adduction P=0.43). The intervention group showed increases in passive torque (P=0.002), peak concentric torque (P<0.001), and peak eccentric torque (P<0.001), independently of FAC alignment. These results suggest that FAC varus alignment influences the effects of strengthening and should be considered when hip and trunk muscle strengthening is used to reduce pelvic drop during walking.

Full textAbstract:
The pelvic structure in non-avian archosaurs plays a key role in understanding the evolution of terrestrial locomotor patterns because the pelvis contains major attachment sites for proximal hind limb musculature. In order to investigate patterns of pelvic evolution in archosaurs, this study compiled three pelvic indices, as well as femoral head orientation, for 92 archosaur taxa. With the metrics and a reconstructed supertree, we examined the correlated evolution of the pelvis and femur, the correlation among pelvic components, and temporal trends in the evolution of the pelvis. The result shows that archosaurs with medially directed femoral heads have more cranially shifted iliac centroids and more posteriorly rotated pubes than taxa with anteromedially directed femoral heads. The craniad shift of the iliac centroid might be correlated to the posterior rotation of pubis. The pelvic structures of pterosaurs, ornithischians, sauropods, and avetheropods occupy a different morphospace from basal archosaurs, pseudosuchians, basal dinosauromorphs, basal theropods, and basal sauropodomorphs in having more cranially expanded ilia, more posteriorly rotated pubes, and medially deflected femoral heads. This may imply that pterosaurs and those derived dinosaurs independently underwent similar shifts in thigh muscles and locomotion. The evolutionary model fitting supports the early-burst model for iliac and pubic metrics in more inclusive archosaur clades, indicating that larger changes of archosaur pelves occurred in early times of the clade's history.

Full textAbstract:
We have observed that birds of several different taxa move their tails in conjunction with sound production. These observations suggested to use that tail movements might also be associated with ventilation. Since we hypothesized that rhythmic movements of the tail and pelvis will ventilate the lungs, the activities of tail, epaxial and cloacal muscles of the pigeon were examined. Electromyograms (EMGs) were recorded from these muscles while ventilation was monitored. A muscle was considered to have ventilatory activity when the EMG activity had an obvious correlation to either inspiration or expiration. To obtain further information about the correlation between muscular activity and ventilation, we induced hyperpnea by administering 5% CO2. We report that the tail muscles that function as expiratory muscles are the M. caudofemoralis, the M. pubocaudalis internus and the M. pubocaudalis externus. We refer to these as the suprapubic abdominal muscles to distinguish them from the infrapubic (ventral) abdominal muscles. These muscles depress the pelvis and the uropygium and compress the thoracoabdominal cavity. M. transversus cloacae functions as an expiratory muscle by protracting the cloaca or by reducing its compliance. Of the suprapubic muscles we studied, the only inspiratory muscle is the axial muscle, M. longissimus dorsi. M. longissimus dorsi acts at the notarial-synsacral junction to elevate the pelvis. The rocking movements of the notarial-synsacral joint appear to be important for ventilation during conditions in which the sternum is ‘fixed’, such as when the bird is resting on its breast. We suggest that a division of labor may exist between the infra- and suprapubic abdominal muscles during ventilation such as panting or vocalization.

Full textAbstract:
Stress urinary incontinence (SUI) is a typical quality of life disease in women. The strengthening of the pelvic floor muscle (PFM) is considered effective to prevent this. Specifically, PFM activity is affected by individual pelvic shape and posture. Therefore, it is necessary to analyze muscle activity by considering the individual differences. In this study, individual pelvic alignment was estimated from the feature values of natural gait via multiple regression analysis. In addition, individual pelvic feature points were derived from X-ray images and used to deform the standard model to obtain individual pelvic shapes. Results indicate that the residual averages of the estimated feature angles were less than 2° in most cases. Subsequently, measurements of the pelvis were obtained via MRI to evaluate the estimated pelvis shape. The results indicate that individual adaptation leads to muscle attachment positions, which are important in the muscle activity analysis, and closer to the true MRI value when compared to that of the standard pelvic model.

The possibility of using the results of functional muscle testing in the evaluation of the preventive efficacy of the physical education of children in primary school is discussed. The results of the evaluation of the functional state of the pectoral muscles and muscles of the shoulder girdle, muscles of the pelvis and lower extremities in 59 first grade pupils in the dynamics of 2 years of the learning of the physical education differentiated according to the gender (the grade of girls and the grade of boys). The elective part of the educational program of physical education consisted of separate units focused on the development of mainly flexibility and coordination in girls, strength, and endurance - in boys. It is established that most often the decreasing of muscles elasticity was characteristic of pectoralis muscles and shoulder girdle muscles compared to the muscles of the pelvis and lower extremities. Peculiarities of the distribution of the enslavement of muscles and the dynamics of their functional state in children of different genders in the learning process are established. The conclusion about the expediency of functional muscle testing for hygienic evaluation of the preventive efficacy of physical education in primary school was made.

Aim - to identify the features of the anatomical structure of the muscles acting on the hip joint in the fetal period of prenatal ontogenesis. Material and methods. The study was carried out on corpses of 200 fetuses aged from 12th to 38th weeks. Anatomical and morphometric research methods were used. Results. As a result of the study, it was established that the muscles of the pelvis and thigh of the fetus are different from the definitive ones: more heads are noted, a different direction of force action vector, functional indicators of the extensor and rotator muscles prevail. There are critical periods of organogenesis of functional muscle groups. Conclusions. The main trend of organogenesis of the muscles of the pelvis and thigh is the fusion of small muscle insertions into larger organs. A feature of the fetal muscles acting on the hip joint is the morpho - functional predominance of the insteps and adductor muscles that create the necessary conditions for the hip joint morphogenesis. The 20th-22th and 28th-30th weeks of intrauterine development are critical periods in human hip joint morphogenesis.

Full textAbstract:
The problem of distribution of Trichinella larvae in transversus stripe skeletal muscles of animals is quite relevant. Literature sources present a lot of contradictory information on this issue. According to a number of authors, carnivores’, including canines’, shoulder muscles and muscles of the forelimbs, pelvis and hind limbs are the most intensely affected. Other researchers provide evidence that the highest numbers of Trichinella larvae are recorded in the muscles of the truncus and head. Furthermore, information about intensely affected muscles is of great importance for the diagnosis of trichinosis. The results of our studies showed that the highest rates of infection intensity in spontaneously infected raccoon dogs were noted in the diaphragm. Less affected were the large masseter muscle, intercostal muscles and muscles of the tongue root. Trichinella larvae were practically not found in the shoulder muscles and muscles of the forelimbs, pelvis and hind limbs. Thus, the highest number of Trichinella larvae was recorded in the muscles of the truncus and head of the spontaneously infected raccoon dogs that we studied.

Full textAbstract:
The purpose of this study was to investigate the differences in muscle activity of the lumbar and pelvic extensor muscles during the hyperextension and reverse hyperextension exercises. Fifteen healthy and weight-trained volunteers (8 women, 7 men) were recruited from a university setting. Electromyographic (EMG) activity of selected hip and trunk extensor muscles was recorded during the execution of a hyperextension and a reverse hyperextension. Three muscles were analyzed: lumbar erector spinae (ES), biceps femoris (BF) and gluteus maximus (GM). The amount of external load used by each individual was determined by equating the amount of torque produced at the hip joint for both exercises. Participants performed two trials of each exercise, and completed at least three repetitions within the eight-second data collection period. Peak integrated EMG (iEMG) activity was expressed as a percentage of maximal voluntary isometric contraction (%MVC). A two-way repeated measures analysis of variance (ANOVA) failed to demonstrate significant differences in %MVC activity between the two exercises, (p>0.05). A comparison of the hyperextension and reverse hyperextension exercises revealed that under similar loading conditions, there is no significant difference in muscle activity of the lumbar and hip extensor muscles.School of Physical Education

Full textAbstract:
But: L’attention semble avoir un impact sur le fonctionnement des muscles périnéaux.Matériels : L’activité électromyographique (EMG) du sphincter anal externe (SAE) a été receuillie au cours d’effort de contractions périnéales volontaires et reflexe (provoquées par la toux) réalisées en réponse à un stimulus au marteau reflexe chez des femmes volontaires saines avec et sans épreuve de charge cognitive (ECC). Le temps de réaction (RT1) correspondant à la latence entre le stimulus et le début d’activité EMG du SAE lors d’une contraction périnéale volontaire, le RT3, correspondant au temps de latence entre le début d’activité EMG du SAE et le début d’activité EMG des muscles intercostaux externes (ICE) lors d’un effort de toux, ont été mesurés. Après randomisation (1/2) 13 femmes ont bénéficié d’une rééducation en double tache (cognitivo-musculaire) et 26 femmes constituaient le groupe témoin. Ces mêmes paramètres ont été enregistrés avant et apres rééducation dans les deux groupes.Resultats: Une ECC provoque un allongement du RT1 par un facteur 3,98 (p<0,001). Une ECC entrainne une diminution de 29% de la contraction périnéale réflexe: RT3 était respectivement de -80.00 ms sans ECC contre -56,7 ms en cas d’ECC (r=0,7, p=0,0045). Dans le groupe « rééducation » le RT1 en présence d’une ECC passait de 461,1 à 290,7 ms (r=0,6, p=0,006) contre 370 à 343 ms dans le groupe témoin (r=0,9, p=NS). Le RT3 dans le groupe « rééducation » en absence d’une ECC passait de -68,5 à -127,8 ms (r=1,9, p=0,03) et en présence d’une ECC de -42,6 ms à -59,3 ms (r=1,4, p=0,04). Conclusion: Une rééducation specifique corrige les effets provoqués par une ECC sur la contraction périnéaleAims: Attention may be involved in pelvic floor muscles (PFM) Methods: The electromyographic (EMG) activity of the external anal sphincter (EAS) was recorded on healthy female volunteers, during voluntary and involuntary (induced by cough) PFM contraction, elicited by local stimulation, combined (or not) with a mental Distraction Task (DT). Reaction time (RT1), ie. the latency between stimulus and the onset of EAS EMG activity, RT3, ie. the latency between the onset of EAS EMG activity and the onset of External intercostal muscle (EIC) (cough) were measured. Following randomisation (2/1) 13 volunteers underwent dual task cognitive (an attentional test and PFM exercises) rehabilitation program and 26 were the control group (no specific instruction). RT1 and RT3 were recorded before and after the program in both group.Results: The mental distraction task led to a 3.98 times greater reaction time between stimulus and EAS EMG activation (RT1), (p<0.001). DT led to a 29% shorter anticipation of the involontary PFM contraction: RT3 were respectively -80.00 ms without a DT versus -56.67 ms with a DT (r=0.7, p=0.004). In the rehabilitation group RT1 in DT conditions decreased from 461.1 ms to 290.7 ms (r=0.6, p=0.006)vs 370 to 343 ms in the control group (r=0.9, p=NS). In the study group RT3 without a DT increased from −68.5 ms to −127.8 ms (r=1.89, p = 0.03) and from 42,6 ms to -59,3 ms with a DT (r= 1.4, p=0.04).Conclusions: A specific dual task rehabilitation can prevent the effect of DT on PFM contraction characteristics

Contexte : Le cancer de l'endomètre est le plus fréquent des cancers gynécologiques. Il a été
suggéré que les traitements oncologiques entraînent des dysfonctions des muscles du plancher pelvien. Ces dysfonctions pourraient contribuer au développement de conditions débilitantes comme la douleur lors des relations sexuelles (dyspareunie) qui atteint plus de la moitié des survivantes. Or, à l'heure actuelle, aucune étude n'a investigué la fonction des muscles du plancher pelvien en lien avec la dyspareunie chez des survivantes d'un cancer de l'endomètre. Objectifs : L'objectif principal vise à explorer les différences quant à la fonction des muscles du plancher pelvien entre des survivantes d'un cancer de l'endomètre atteintes de dyspareunie et des femmes
sans douleur ayant subi l'hystérectomie totale pour des raisons bénignes. L'objectif secondaire est d'explorer les différences entre les deux groupes quant aux variables urogynécologiques, sexuelles, psychologiques et sociales. Méthodologie : Dans cette étude comparative exploratoire bicentrique, des survivantes d'un cancer de l'endomètre atteintes de dyspareunie (n=7) et des femmes asymptomatiques (n=7) ont assisté à une séance d'évaluation menée par une physiothérapeute. Les deux groupes ont été équilibrés selon l'âge, l'indice de masse corporelle et le nombre d'accouchements par voie vaginale. La fonction des muscles du plancher pelvien, y compris le tonus, la force maximale, la vitesse de contraction, la coordination et l'endurance, a été évaluée à l'aide du spéculum dynamométrique. Des questionnaires validés ont permis d'évaluer les variables secondaires. Des tests de Mann-Whitney ont été employés pour comparer les deux groupes quant à la fonction des muscles du plancher pelvien et les variables urogynécologiques, sexuelles, psychologiques et sociales (!=0,050). Résultats : Concernant la fonction des muscles du plancher pelvien, les survivantes atteintes de dyspareunie ont démontré un tonus à une ouverture vaginale
minimale supérieur (p=0,018) et une endurance inférieure (p=0,048) aux femmes asymptomatiques. Les survivantes ont également présenté plus d'incontinence fécale (p=0,005) et une fonction sexuelle inférieure (p=0,004) comparativement aux femmes asymptomatiques. Aucune différence n'a été détectée pour les variables psychologiques et sociales. Conclusion : Les résultats de cette étude exploratoire suggèrent des dysfonctions des muscles du plancher pelvien, notamment un tonus supérieur et une endurance inférieure, chez les survivantes d'un cancer de l'endomètre atteintes de dyspareunie. D'autres études sont nécessaires afin de confirmer ces résultats. Ces constats préliminaires pourraient servir d'assises pour mieux comprendre les dysfonctions des muscles du plancher pelvien impliquées dans la dyspareunie chez cette population.Abstract : Context: Endometrial cancer is the most common cancer in gynecological cancers. Oncological treatments are suggested to cause pelvic floor muscle dysfunction that could contribute to the development of debilitating conditions such as pain during sexual intercourse (dyspareunia), which affects more than half of survivors. However, to date, no study investigated pelvic floor muscle function in relation to dyspareunia in endometrial cancer survivors. Objectives: The main objective is to explore differences in pelvic floor muscle function between endometrial cancer survivors with dyspareunia and women without pain who underwent a total hysterectomy for benign conditions. The secondary objective is to explore differences between the two groups on urogynecological, sexual, psychological and social variables. Methodology: In this exploratory, bicentric comparative study, endometrial cancer survivors with dyspareunia (n=7) and asymptomatic women (n=7) attended one evaluation session conducted by a physiotherapist. The two groups were balanced in terms of age, body mass index and number of vaginal deliveries. The pelvic floor muscle function, including tone, maximal strength, contraction speed, coordination and endurance, was assessed with the dynamometric speculum. Validated questionnaires were used to evaluate secondary variables. Mann-Whitney tests were used to compare the two groups on muscular, urogynecological, sexual, psychological and social variables (!=0.050). Results: Concerning pelvic floor muscle function, survivors with dyspareunia demonstrated higher tone at a minimal vaginal aperture (p=0.018) and lower endurance (p=0.048) compared to asymptomatic women. Survivors also presented more fecal incontinence (p=0.005) and lower sexual function (p=0.004) compared to asymptomatic women. No differences were detected for psychological and social variables. Conclusion: The results of this exploratory study suggest impaired pelvic floor muscle function, notably higher tone and lower endurance, in endometrial cancer survivors with dyspareunia. Further studies are needed to confirm these findings. This preliminary evidence can be used as empirical data to better understand pelvic floor muscle impairments implicated in dyspareunia in this population.

Contextualização: Observa-se na literatura que indivíduos assintomáticos podem não apresentar pré-ativação muscular de estabilizadores primários e não há estudos que apontem para os motivos da alteração no tempo de início de ativação muscular nessa população. Além disso, estudos preliminares em nosso laboratório mostraram que indivíduos assintomáticos apresentaram alterações em testes físicos e funcionais relacionados à capacidade de estabilização da região lombo-pélvica. Objetivo: Estudar o comportamento de pré-ativação dos músculos transverso do abdome/oblíquo interno (TrA/OI) e multífido lombar (ML), a capacidade de estabilização lombo-pélvica e a relação entre ambos. Metodologia: Foram selecionados 27 voluntários assintomáticos de ambos os sexos, com idades entre 20 e 28 anos (média = 23,85 ±2,21). Os voluntários foram submetidos a Testes Físicos Funcionais (TFF) para avaliar a capacidade de estabilização lombo-pélvica (Testes de Coordenação e Equilíbrio, Flexibilidade, Resistência e Comprimento e Força) e à Determinação de início de ativação muscular do TrA/OI e ML por meio da eletromiografia de superfície (EMG-S) durante movimento rápido de flexão do membro superior. Resultados: Embora a pré-ativação tenha sido o comportamento mais freqüente a ausência de pré-ativação do TrA/OI e ML ocorreu para alguns voluntários, sendo mais freqüente no músculo TrA/OI (26.6%) do gênero feminino. Nos TFF nenhum voluntário da amostra conseguiu obter valores de normalidade em todos os testes realizados e aqueles com maior número de voluntários com alteração foram: teste de flexibilidade do reto femoral e espinhais lombares, teste de enrolamento repetitivo do tronco, teste estático de resistência das costas de Sorensen e o teste de comprimento e força para o glúteo máximo.

Contextualization: It is observed in the literature that asymptomatic individuals may not have muscular pre-activation of primary stabilizers and there are no studies that point to the reasons for the change in time of onset of the muscle activation in this population. Furthermore, preliminary studies in our laboratory showed that asymptomatic individuals presented alterations in physical and functional tests with relationship the capacity of lumbo-pelvic stabilization. Objective: The study of pre-activation behavior of transversus abdominis/internal oblique muscle (TrA/OI) and lumborum multifidus (ML), the lumbo-pelvic stabilization capacity and the relationship of both. Methodology: Were selected 27 asymptomatic individuals of both sexes, with age between 20 e 28 years (mean = 23,85 ±2,21). The volunteers were submitted to a Physical Functional Tests (FFT) to evaluate a lumbo-pelvic stabilization capacity (coordination tests, balance, flexibility, endurance, length and force) and the determination of muscle activation onset of the TrA/OI and ML with superficial electromyography (EMG-S) during fast flexion arm movement. Results: Although pre-activation has been a usual result, the pre-activation absent of TrA/OI and ML happened in some volunteers, being more frequent for TrA/OI (26.6%) in the female gender. At TFF neither volunteers of the sample get regular scores in all tests executed. Those tests with more number of alterations were: rectus femoris and spinal lumbar flexibility, Sorensen static back endurance, and length and force to gluteus maximus. However, only repetitive trunk curl test showed great sensibility and specificity value with the primary stabilizers behavior of pre-activation

Resumo: O assoalho pélvico (AP) feminino é uma estrutura complexa e vulnerável, suscetível a uma série de alterações funcionais ao longo da vida. Ampliar o conhecimento sobre esta estrutura poderia prevenir ou mesmo tratar tais disfunções. Objetivo: (1) Avaliar e comparar a contratilidade dos músculos do assoalho pélvico (MAP) em diferentes fases do ciclo vital feminino: nuligestas; primigestas; puérperas primíparas; climatéricas e pós-menopausadas. (2) Correlacionar a contratilidade dos MAP e sua coativação a partir da contração dos músculos transverso abdome/oblique interno (TrA/OI) com os fatores: idade; prática de atividade física; gestação; Índice de Massa Corpórea (IMC); paridade; presença e severidade dos sintomas urinários. Métodos: 331 mulheres participaram do estudo e foram avaliadas através dos questionários: International Consultation on Incontinence Questionnaire - Short Form (ICIQ UI-SF) e International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB) para estudo dos sintomas urinários e eletromiografia (EMG) dos MAP para avaliação da contratilidade. Destas mulheres 92 foram submetidas também à EMG dos músculos TrA/OI e analisadas de acordo com os fatores propostos para estudar a influenciar da contratilidade na coativação. Resultado: Entre os grupos estudados, as nuligestas apresentam maior contratilidade (46.59±16.83?V) dos MAP, seguido do grupo das primigestas (35.31±18.22?V), puérperas de parto cesariana (33.28±13.00?V), puérperas de parto vaginal (31.23±16.12?V), climatéricas (25.81±17.57?V) e pós menopausadas (21.23±15.11?V). Houve correlação negativa entre a contratilidade dos MAP e a idade (p<0.0001), paridade (p<0.0001), ICIQ-SF (p=0.0001) e ICIQ OAB (p=0.0006). Não foi verificada correlação entre MAP e IMC (p=0.1348) e as mulheres que praticam atividade físca apresentam maior contratilidade dos MAP (p=0.03). Sobre os fatores que podem interferir na coativação foram significativos: a gestação (p=0.01), prática de atividade física (p=0.03) e altos valores do escore do ICIQ IU SF (p<0.0001). Em análise multivariada a atividade física juntamente com ICIQ IU SF influenciaram a contratilidade dos MAP e TrA/OI (p<0.001). Conclusão: A contratilidade dos MAP durante o ciclo vital feminino apresenta-se na seguinte ordem decrescente: nuligestas, primigestas, primíparas pós parto cesariana, primíparas pós parto vaginal, climatéricas e pós menopausadas. Os MAP apresentam sua contratilidade correlacionada inversamente com a idade, paridade, e escores do ICIQ SF e ICIQ OAB. A coativação entre o TrA/OI e os MAP é influenciada diretamente pela atividade física, e inversamente pela gestação e ICIQ IU SF. Em análise multivariada, verificou-se que, conjuntamente, a coativação é influenciada diretamente pela prática de atividade física e inversamente pelo escore ICIQ IU SF
Abstract: The female pelvic floor (PF) is a complex and vulnerable structure, susceptible to a number of functional changes throughout life. Increasing the knowledge of this structure could prevent or even treat such disorders. Objective: (1) To evaluate and compare the contractility of the pelvic floor muscle (PFM) at different stages of the female life cycle: nulliparous; primigravidae; primiparous postpartum women; climacteric and menopause. (2) To correlate the contractility of the PFM and their coactivation from the contraction of the transversus abdomen muscles/ internal oblique (TrA/IO) with the following factors: age; physical activity; pregnancy; Body Mass Index (BMI); parity; presence and severity of urinary symptoms. Methods: 331 women were evaluated through questionnaires: International Consultation on Incontinence Questionnaire - Short Form (ICIQ-UI SF) and International Consultation on Incontinence Questionnaire Overactive Bladder (OAB-ICIQ) for study of urinary symptoms and PFM electromyography (EMG) for contractility assessment. Of these women 92 were also submitted to the TrA EMG / IO muscles and analyzed according to the proposed factors to study the influence of contractility in coactivation. Results: Among the groups, the nulliparous have greater contractility (46.59 ± 16.83_V) of PFM, followed by the group of first pregnancy (35.31 ± 18.22_V), cesarean birth mothers (33.28 ± 13.00_V), vaginal birth mothers (31.23 ± 16.12_V), weather (25.81 ± 17.57_V) and postmenopausal (± 15.11_V 21:23). There was a negative correlation between the contractility of PFM and age (p <0.0001), parity (p <0.0001), ICIQ-SF (p = 0.0001) and ICIQ OAB (p = 0.0006). There was no correlation between the contractility of PFM and BMI (p = 0.1348). Women who practice physical activity have greater contractility of PFM About the factors that can interfere with coactivation were significant: pregnancy (p = 0.01), physical activity (p = 0.03) and high values of the ICIQ UI SF score (p<0.0001). In multivariate analysis, physical activity along with ICIQ UI SF influence the contractility of PFM and TrA/IO (p<0.001). Conclusion: The contractility of PFM during the female life cycle is presented in the following descending order: nulliparous, primiparous, primiparous after cesarean delivery, primiparous after vaginal delivery, climateric and postmenopausal. The PFM present their contractility inversely correlated with age, parity, and scores of ICIQ SF and ICIQ OAB. The co-activation between the TrA /IO and PFM is directly influenced by physical activity, and inversely by pregnancy and ICIQ UI SF. In multivariate analysis, it was found that, together, the co-activation is directly influenced by physical activity and inversely by ICIQ UI SF score

Resumo: Introdução e objetivos: Os exercícios dos músculos do assoalho pélvico e do abdome devem ser minuciosamente avaliados e orientados para que, através da sinergia, haja aperfeiçoamento na qualidade dos exercícios e se conheça as reações desencadeadas durante a realização dos mesmos. É de grande importância entender a sinergia do recinto abdomino pélvico em diferentes fases da vida feminina, como na gestação e puerpério, pois, nestas fases surgem grandes alterações na musculatura abdominal e do assoalho pélvico, necessitando de maior atenção para que os exercícios sejam realmente eficazes. Sendo assim, este estudo observacional, teve como objetivo a avaliação eletromiográfica simultânea dos músculos transverso do abdome e do assoalho pélvico, durante exercícios comumente realizados por mulheres em fase gestacional e/ou puerperal. Métodos: Este estudo, clínico, prospectivo, observacional e controlado foi constituído de 81 mulheres, com idade média de 23,56 anos (DP=4,82), as quais foram divididas em quatro grupos: Grupo (A): 20 nulíparas; Grupo (B): 25 primigestas, com idade gestacional maior ou igual à 24 semanas; Grupo (C): 19 puérperas em fase remota (40 a 60 dias), pós parto vaginal; Grupo (D): 17 puérperas em fase remota (40 a 60 dias), pós parto cesariana. Inicialmente foi realizado a avaliação funcional do assoalho pélvico (AFA) e posteriormente o probe endovaginal foi posicionado. A atividade elétrica dos músculos abdominais e do assoalho pélvico foi registrada simultaneamente por eletromiografia de superfície. As contrações solicitadas do assoalho pélvico e do abdome foram máximas, voluntárias e repetidas três vezes, sendo as contrações do abdome do tipo isométrico e isotônico. Os resultados obtidos foram submetidos à análise de variância (ANOVA) com aplicação de Teste Contrastes Ortogonais através do programa estatístico "R", da R Development Core Team (2008). Os contrastes realizados foram: Contraste 1- Nulíparas versus demais grupos; Contraste 2- Gestantes versus Puérperas e Contraste 3- Puérperas pós parto vaginal versus Puérperas pós parto cesariana. O nível de significância adotado foi abaixo de 1%. Resultados: Durante os exercícios para o assoalho pélvico, foi mostrada significância da sinergia abdominal das mulheres nulíparas (p=0,0007) quando comparadas aos outros grupos. Os demais contrastes realizados para verificação da sinergia durante exercício do assoalho pélvico não apresentou significância (p=0,4509 e p=0,2786). Ao realizar o exercício abdominal do tipo isométrico, as nulíparas mostraram valores significativos ao serem comparadas aos demais grupos estudados (p=0,00001). Entretanto, quando os outros grupos foram comparados entre si, não houve significância (p=0,7949 e 0,9633). Quando solicitado o exercício abdominal isotônico, as nulíparas se mostraram sinérgicas quando comparadas às demais mulheres em fases específicas (p=0,00002) o que não ocorreu nas demais comparações (p=0,8355 e p=0,4662). Conclusão: Há sinergia entre os músculos transverso do abdome/oblíquo interno e o assoalho pélvico em mulheres, jovens, nulíparas e saudáveis. Mulheres em fase gestacional e puerperal remota não apresentam co-ativação dos músculos transverso do abdome/oblíquo interno e do assoalho pélvico, independente do tipo de parto e exercício solicitado
Abstract: Introduction and objectives: Pelvic floor and abdominal muscles exercises must be carefully evaluated and coached so that throughout synergy there can be improvement of the quality of the exercises as well as a greater knowledge of the reactions produced during their execution. It is of great importance to understand the synergy of the abdominal-pelvic area during the different stages of the women such as gestation and puerperium, since in those phases there are many and great alterations of the abdominal and pelvic floor muscles that require more attention during exercises executions resulting in real efficacy. This observational study had as objective to evaluate through simultaneous electromyography the transversus abdominis, obliquous internus and pelvic floor muscles during commonly used exercises performed by women in gestational and/or puerperal phases. Methods: This is a clinical, observational, prospective and controlled study which was composed of 81 women with a mean age of 23. 56 years old (SD=4,82) who were divided into 4 groups: Group (A): 20 nulliparous; Group (B): 25 primiparous with gestational age superior or equal to 24 weeks; Group(C): 19 in late puerperal phase (40-60 days) after vaginal delivery; Group (D): 17 in late puerperal phase (40- 60 days) after cesarean delivery. The Functional Pelvic Floor Evaluation (AFA) was made prior to the endovaginal probe positioning. The electric activity of the abdominal and pelvic floor muscles was simultaneously recorded through surface electromyography. The requested contractions of those muscles were maximum, voluntary and performed for three times, being both isometric and isotonic. The results were analyzed by ANOVA (analysis of variance) with Orthogonal Contrast Test using the statistic program "R" from R Development Core Team (2008). The used contrasts were: Contrast 1: Nulliparous versus other groups; Contrast 2-Pregnant versus Puerperals and 3-After Vaginal Delivery Puerperals versus After Cesarean Delivery Puerperals. The significance level was below 1%. Results: During exercises of the pelvic floor muscles, there was a synergic response of the abdominal muscles in the nulliparous group (p=0,0007) when compared to the other groups. There was no significance for the other contrasts regarding pelvic floor muscles exercises (p=0,4509 and p=0,2786). There were significant values for the nulliparous women during isometric abdominal exercise when compared to the other groups (p=0,00001). However when the other groups were compared among each other, there were no significant values (p=0,7949 and 0,9633). During isotonic abdominal exercise, the nulliparous women showed synergy when compared to the other women who were in specific stages (p=0,00002). It did no happen with other comparisons (p=0,8355 and p=0,4662). Conclusão: There is synergy among transversus abdominis, obliquous internus and pelvic floor muscles in young, nulliparous and healthy women. Pregnant and late puerperal women do not present co-activation of the transversus abdominis, obliquous internus and pelvic floor muscles, independently of the delivery mode

Resumo: Introdução: O treinamento dos músculos do assoalho pélvico (TMAP) é uma técnica amplamente utilizada pela fisioterapia com o objetivo de aumentar a força muscular, aumentar o fluxo sanguíneo local e a mobilidade pélvica, além de informar a mulher sobre a sua anatomia e melhorar a conscientização corporal. O treinamento com esse foco poderia influenciar de maneira positiva a função dos músculos do assoalho pélvico (MAP) e a função sexual feminina. Objetivo: Avaliar as funções muscular e sexual feminina pré e pós TMAP de mulheres em idade reprodutiva sem disfunção uroginecológica e/ou sexual. Métodos: Ensaio clínico incluindo 68 mulheres nulíparas em idade reprodutiva sem disfunção uroginecológica e/ou sexual. A função dos MAP foi mensurada pré e pós TMAP pelas pressões intravaginais, potencial eletromiográfico de superfície (sEMG) e palpação bidigital. A função sexual foi avaliada pré e pós TMAP pelo questionário Female Sexual Function Index (FSFI) que enfatiza seis domínios (desejo, excitação, lubrificação, orgasmo, satisfação sexual e dor). O TMAP foi realizado em grupo, uma vez por semana durante 8 semanas, com 45 minutos de duração, usando 11 diferentes posições. Para cada posição foram solicitadas 5 contrações tônicas sustentadas por 6 segundos com igual tempo de relaxamento entre cada contração e 5 contrações fásicas, totalizando 110 contrações a cada sessão. As voluntárias foram orientadas a realizar em casa 30 contrações todos os dias da semana. Resultados: Foram observadas diferenças significativas ao compararmos os valores máximos das avaliações das pressões intravaginais pré e pós TMAP das contrações fásicas 41,7±13,7 vs. 47±14 (p=0,0023), tônicas de 10 segundos 42,7±13,8 vs. 47,7±15 (p=0,0085) e tônicas de 60 segundos 42,1±13 vs. 47,5±14,5 (p=0,0013) respectivamente. Também foram observadas diferenças significativas nos valores máximos do sEMG das avaliações pré e pós TMAP das contrações fásicas 27,7±11,2 vs. 31,3±12,6 (p=0,0009), tônicas de 10 segundos 27,7±10,9 vs. 31,5±13,6 (p=0,0017), tônicas de 60 segundos 28,6±11,8 vs. 31,1±13 (p=0,0232) e tempo de contração em segundos 41,7±22,1 vs. 49,3±27,7 (p=0,0252) respectivamente. Foram encontradas diferenças significativas pré e pós TMAP no escore total do FSFI 29,8±3,7 vs. 31,9±2,7 (p<0,0001) e nos domínios desejo 4,4±0,9 vs. 4,7±0,8 (p=0,0076), excitação 4,8±0,8 vs. 5,2±0,5 (p=0,0001), lubrificação 5,2±0,8 vs. 5,5±0,5 (p=0,0140) e orgasmo 4,5±1,4 vs. 5,3±0,9 (p<0,0001) respectivamente. Conclusão: O TMAP aumenta a função dos MAP e melhora a função sexual de mulheres em idade reprodutiva sem disfunção uroginecológica e/ou sexual
Abstract: Introduction: Pelvic floor muscles training (PFMT) is a technique widely used for physical therapy in order to increase muscle strength, increase local blood flow and pelvic mobility and inform women about their anatomy and improve awareness body. Training with this focus could positively influence the function of the pelvic floor muscles (PFM) and female sexual function. Objective: To evaluate the muscular function and female sexual function pre and post PFMT of women of reproductive age without urogynecologic and/or sexual dysfunction. Methods: A clinical trial including 68 nulliparous women of reproductive age without urogynecologic and/or sexual dysfunction. The function of the PFM was measured before and after the PFMT intravaginal pressures, potential surface electromyography (sEMG) and palpation bidigital. Sexual function was assessed before and after the PFMT the survey Female Sexual Function Index (FSFI) that emphasizes six domains (desire, arousal, lubrication, orgasm, sexual satisfaction, and pain). The PMAT group was performed once a week for 8 weeks, with 45 minutes using 11 different positions. For each position were requested 5 tonic contractions sustained for 6 seconds with equal relaxation time between contractions and 5 phasic contractions, totaling 110 contractions each session. The volunteers were instructed to perform 30 contractions at home every day of the week. Results: Significant differences were observed when comparing the maximum rating of intravaginal pressure pre and post PFMT of phasic contractions 41.7±13.7 vs. 47±14 (p=0.0023), tonic contractions of 10 seconds 42.7±13.8 vs. 47.7±15 (p=0.0085) and tonic of 60 seconds 42.1±13 vs. 47.5±14.5 (p=0.0013) respectively. There were also significant differences in the maximum values of sEMG pre and post PFMT of phasic contractions 27.7±11.2 vs. 31.3±12.6 (p=0.0009), tonic contractions of 10 seconds 27.7±10.9 vs. 31.5±13.6 (p=0.0017), tonics of 60 seconds 28.6±11.8 vs. 31.1±13 (p=0.0232) and contraction time in seconds 41.7±22.1 vs. 49.3±27.7 (p=0.0252), respectively. There were significant differences pre and post PFMT in total score FSFI of 29.8±3.7 vs. 31.9±2.7 (p<0.0001) and in those areas desire 4.4±0.9 vs. 4.7±0.8 (p=0.0076), arousal 4.8±0.8 vs. 5.2±0.5 (p=0.0001), lubrication 5.2±0.8 vs. 5.5±0.5 (p=0.0140) and orgasm 4.5±1.4 vs. 5.3±0.9 (p<0.0001) respectively. Conclusion: The PFMT increases the function of PFM and improves sexual function in women of reproductive age without urogynecologic and/or sexual dysfunction

Resumo: Este trabalho visa registrar a atividade eletromiográfica dos músculos íliocostallombar (ICL), glúteo máximo (GM), reto do abdome (RA) e reto da coxa (RC) na postura ereta relaxada normal e com as alterações provocadas por elevações nos calcanhares, como ocorre com uso de sapatos de salto, de 2,0, 4,0, 6,0 e 11,0 cm. Para registro dos exames utilizou-se um eletromiógrafo VIKING II de 8 canais, com eletrodos de superficie tipo Beckman, em 10 voluntários"do sexo masculino, na faixa etária entre 16 e 25 anos, sem nenhuma alteração postural considerada patológica. Esta condição foi respeitada com a obtenção da história clínica e exame fisico dos voluntários com uso de um espondilômetro. Os resultados, submetidos a . análise gráfica descritiva a partir da média dos valores de RMS e análise, estatística não paramétrica, mostram que: o m. ICL apresenta-se mais ativo nas posições em que os voluntários estão em pé relaxados sem elevação nos calcanhares e com elevação nos mesmos de 2 cm e menos ativo com os indivíduos utilizando 6 cm de altura de plataforma. O m. GM produziu atividade elétrica relativamente constante em todas as posições, sendo a maior na posição de 11,0 cm de plataforma e a menor com 4,0 cm. Com relação ao m. RC, nas plataformas 11,0 e 6,0 cm apresentou maior atividade ellétrica e a menor na plataforma 4,0 cm. O m. RA prod1J1Ziu atividade eletromiográfica média e crescente à medida em que a plataforma era aumentada de 0,0 para 2,0, depois 4,0, 6,0 e fmalmeNte 11,0 cm de altura. Com esses resultados analisados pudemos concluir que, dos milisculos estudados o mais ativo é o ICL e o menos solicitado é o GM, na postura ereta relaxada, sendo comprovada a importância de todos os músculos estudados nesta posição. A condição que exige menor consumo energético é com uso da plataforma (salto) de 4,0 cm, não sendo portanto a ausência de elevação (salto zero) a melhor para o descanso na, postura ortostática relaxada
Abstract: This task intends to registers the eleetromyographie aetivity of the muscles ilioeostalis lumbar (ICL), gluteus maximus (GM), reetus abdominis (RA) and reetus femoris (RF) in the normal upright postural relaxed and with the alterations provoked by rises on the heels, as it happens when wearing high heels shoes, of 2,0, 4,0, 6,0 e 11,0 eentimeters. For that utilized an eleetromyography VIKING 11 with 8 ehanels, with surfaee eleetrodes Beekman to registrate the eJÇames in 10 subjeets, between 16 and 25 yers old, with no postural ehange eonsidered pathologie. This eondition was respeeted with the obtainment of the elinieal history and phisieal exame of the subjéets using one espondilometer. The results, submeted the graphie analises deseriptive after the average of -the values RMS and statistie analyses no parametrie, show that, the m. ICL shows more aetive in the positions where the people are up relaxed without elevations in the heels and with elevation in 2 em and less aetive with the people wearing 6 em of high on the plataform. The m. GM produeed eleetrieal aetivity relatively eonstant in alI position, being the biggest in the positon 11,0 em of platform and the smalIest with 4,0 em. As for the m. RF, on the platform 11,0 and 6,0 em apresented more eleetrieal aetivity and the least on the platform with 4,0 em . The m. RA produeed eleetromygraphie aetivity average and crescent according to the platfmID was being elevated fi;om 0,0 to 2,0, after 4,0 and 6,0 and fmaIJy increased 11,0 cm of high. With these results analysed we could drow that, with the muscles studied the most active is the ICL and the less solicited is GM, in the upright postural relaxed, being confumed the importance of all; musdes studied in this position. The conditionthat require less energetic consume is with the use of platform with 4,0 cm, not being therefore the absence of elevation (zero) the best for the rest in upright position

Not every case of neurologically based pelvic/genital numbness/incontinence is due to cauda equina syndrome. Pelvic pain, incontinence, and sexual dysfunction can result from treatable peripheral nerve injury or entrapment affecting the pudendal nerves or impar ganglion. Learning the signs, physical exam findings, tests, and surgical options greatly expands a neurosurgeon’s range. The pudendal nerve and nerve to the obturator internus muscle arise after S2, S3, and S4 spinal nerves traverse the piriformis muscle. They exit the sciatic notch with the sciatic nerve but then re-enter the pelvis, where the pudendal nerve then gives off bladder, rectal, and genital branches.

Full textAbstract:
Piriformis syndrome is an entrapment neuropathy caused by compression or irritation of the sciatic nerve as it courses in proximity to the piriformis muscle. Conservative treatment modalities for piriformis syndrome include the use of anti-inflammatory analgesic medications or muscle relaxants. Physical therapy is often employed to correct the abnormal pelvic biomechanics and focus on stretching the piriformis muscle. Prior to proceeding with invasive surgical approaches, this chapter advocates the use of piriformis muscle injection. The technique both confirms the diagnosis and offers therapeutic value while avoiding the risks, expense, and potential adverse outcomes associated with surgical interventions. A combined fluoroscopic and nerve stimulator guided technique is recommended to identify bony landmarks, verify the perisciatic location, confirm intramuscular spread of the injectate, and avoid intravascular injection of particulate steroid. Transient sciatic nerve block caused by spillover of the local anesthetic administered into the piriformis muscle is a common complication.

Full textAbstract:
Involuntary loss of urine is subdivided primarily into stress, urgency, or mixed urinary incontinence. The history and examination aim to identify underlying mechanisms, and indicators of more complex causes, or serious medical conditions. Associated lower urinary tract symptoms (LUTS) should be catalogued in detail. History should also cover symptom bother, as this is the prime driver of therapy. Validated questionnaires are the most effective way to capture aspects of incontinence and associated LUTS. Wider pelvic symptoms, such as pelvic organ prolapse, sexual function, and anal symptoms should also be evaluated. Physical examination needs to cover general aspects, including occult neurological disease. Abdominal and pelvic examination evaluates the genitalia, pelvic floor muscle function, and pelvic masses, along with urethral hypermobility in women and the prostate in men.

Full textAbstract:
In spite of the several experimental and modeling studies on the biomechanical characteristics of the human spine, the role and significance of the intra-abdominal pressure (IAP) in spine mechanics has remained controversial. This study represents a simple analytical and a 3-D finite element model of spine and its surrounding structures to investigate the contribution of IAP to spinal stability. The mathematical model included the lumbar spine column, the abdominal cavity and a muscular layer around it, the rib cage and the pelvic ring. The lumbar spine column was modeled as a beam and the rib cage and pelvis as rigid bodies. The intra-abdominal cavity and the surrounding muscular layer were represented by a thin-wall cylindrical vessel with deformable shell wall. The free body diagram and equilibrium equations of each body of the model were derived while an external load to the rib cage was applied. The equations were then combined with the force-deflection relationships for the beam bending, the IAP fluid volume variation, and the muscle shell traction. Muscle activation levels were simulated by changing the Young’s modulus of the shell in the direction of fibers, up to an upper-limit value which was obtained based on the Valsalva maneuver. In the Finite Element (FE) model, the abdominal cavity was assumed to be cylindrical and filled by fluid with a bulk modulus of IMPa. The surrounding muscular layer was modeled as membrane with transverse isotropic material properties considering their fibers orientation. The spine, rib cage and pelvic ring were modeled by beam elements. The top plate simulated the active and/or passive role of diaphragm through its vertical displacement. The bottom membrane and distal spine were fully constrained. Good agreement between the analytical and FE model results was obtained. A larger external force and/or higher level of muscle activation caused a higher IAP, improving spinal unloading and stability. This effect was more significant for muscles with more horizontally directed fibers, e.g., Transverse Abdominis (TA).

Full textAbstract:
Individuals with weak or paralyzed hip abductors may make use of two methods to reduce pathological gait kinematics as a result of their disability; reducing the need for the hip abductors or developing an equivalent torque on the body. Compensatory motions such as torso tilting or hip hiking “balance” the body reducing the need for the torque that would be developed by the hip abductors. A contralateral crutch develops a body torque that is equivalent to that developed by the hip abductors. Individuals with weak or paralyzed hip abductors intuitively adopt a wide crutch stance, contrary to the prescribed method where the crutches are vertical in the frontal plane. Using a wide stance angle in the frontal plane is hypothesized to improve gait with weak or paralyzed hip abductors more so than when using crutches in the traditional manner. Crutches develop a torque on the body that is equivalent to what would be developed by the hip abductors while standing still. A wide stance angle increases the moment arm that the crutch force acts through while standing still, increasing the torque developed, potentially increasing the positive effect of the crutch which may reduce the need for compensatory motions. However, a similar effect has not been characterized during gait. The hypothesis is that a wide crutch stance angle improves a gait with paralyzed hip abductors more so than a crutch used vertically in the frontal plane. The assumption is that this is accomplished by decreasing energy expenditure and/or reducing the need for compensatory motions more so than a crutch used vertically in the frontal plane. A three-dimensional dynamic model is used to test the hypothesis. The model predicts that excessive pelvis depression and decreased pelvic rotation result when the hip abductors are paralyzed. Compensatory motions, hip hiking and torso tilting, and crutch use are shown to decrease the prevalence of pathological kinematics. Crutch use with a wide stance angle improves gait kinematics more than a vertical crutch with the same body weight supported on it. This study provides evidence that the need for compensatory motions and the prevalence of pathological gait kinematics may be reduced when using a wide crutch stance angle compared to a vertical crutch stance angle.

Full textAbstract:
A physics-based computational model of neonatal Developmental Dysplasia of the Hip (DDH) following treatment with the Pavlik Harness was developed to obtain muscle force contribution in order to elucidate biomechanical factors influencing the reduction of dislocated hips. Clinical observation indicates that reduction occurs in deep sleep and involves passive muscle action. Consequently, a set of five (5) adductor muscles, namely, the Adductor Brevis, Adductor Longus, Adductor Magnus, Pectineus, and Gracilis were identified as mediators of reduction using the Pavlik Harness. A Fung-type model was used to characterize the hyperelastic stress-strain muscle response. Four grades (1–4) of dislocation as specified by the International Hip Dysplasia Institute (IHDI) were considered. A three-dimensional model of the pelvis-femur-lower limb assembly of a representative 10 week-old female was generated based on CT scans of a 6-month and 14-year old female as well as the visible human project with the aid of anthropomorphic scaling of anatomical landmarks. The muscle model was calibrated to achieve equilibrium at 90° flexion and 80° abduction. The hip was computationally dislocated according to the grade under investigation, the femur was restrained to move in an envelope consistent with Pavlik Harness restraints, and the dynamic response under passive muscle action and under the effect of gravity was resolved using the ADAMS solver in Solidworks. Results of the current model with an anteversion angle of 50° show successful reduction IHDI Grades 1–3, while IHDI Grade 4 failed to reduce with the Pavlik Harness. These results are consistent with a previous study based on a simplified anatomically-consistent synthetic model and clinical reports of very low success of the Pavlik Harness for Grade 4. However, our model indicates that it is possible to achieve reduction of Grade 4 dislocation by hyperflexion. This finding is consistent with clinical procedures that utilize hyperflexion to help achieve reduction for patients with severe levels of DDH for whom the Pavlik Harness fails.

Full textAbstract:
Pelvic Organ Prolapse (POP) is a condition of the female pelvic system suffered by a significant proportion of women in the U.S. and more across the globe, every year. POP is caused by the weakening of the pelvic floor muscles and musculo-connective tissues due to child birth, menopause and morbid obesity. Prolapse of the pelvic organs namely the urinary bladder, uterus, and rectum into the vaginal canal can cause vaginal discomfort, strained urination or defecation, and sexual dysfunction. To date, success rates of native tissue POP surgeries vary from 50–70% depending on the definition of cure and time-point of assessment. A better understanding of the mechanics of prolapse may lead to improvement in surgical outcomes. In the current work, the mechanics of progression of anterior and posterior vaginal prolapse were modeled to understand the effect of bladder fill and posterior vaginal stresses using computational approaches. A realistic and full-scale female pelvic system model, comprised of the urinary bladder, vaginal canal, uterus, rectum, and fascial connective tissue, was developed using image segmentation methods. All of the relevant loads and boundary conditions were applied based on a comprehensive study of the anatomy and functional morphology of the female pelvis. Hyperelastic material models were adopted to characterize all pelvic tissues, and a non-linear analysis was invoked. In the first set of simulations, a realistic bladder filling and vaginal tissue stiffening in prolapse were modeled and their effects on the anterior vaginal wall (AVW) were estimated in terms of the induced stresses, strains and displacements. The degree of bladder filling was found to be a strong indicator of stress build-up on the AVW. Also, vaginal tissue stiffening was found to increase the size of the high stress zone on the AVW. The second simulation consisted of modeling the different degrees of posterior vaginal wall (PVW) prolapse, in the presence of an average abdominal pressure. The vaginal length was segmented into four sections to study the localized stresses and strains. Also, a clinically well-known phenomena known as the kneeling effect was observed with the PVW in which the vaginal wall displaces away from the rectum and downward towards the vaginal hiatus. All of these results have relevant clinical implications and may provide important perspective for better understanding the mechanics of POP pathophysiology.

Millions of people worldwide suffer from an involuntary leakage of urine, a condition known as urinary incontinence. In the US alone, the estimated cost of managing this is more than $16 billion [1]. Stress urinary incontinence (SUI), the most common form, is characterized by involuntary leakage of urine from effort or exertion during actions such as laughing, coughing, or sneezing. SUI largely occurs as a result of weak or damaged pelvic muscles that support the bladder and urethra, which makes the urethra unable to maintain its seal and allows urine to leak. Current SUI treatments such as pelvic floor muscle training, vaginal inserts, pharmacologic therapeutics, and surgical procedures are limited by ineffectiveness and/or subsequent complications [2, 3].

Full textAbstract:
Abstract Pelvic reconstruction is required to restore the functional activity after an internal hemipelvectomy. The available pelvic prosthesis has several complications and long terms issues (such as stability, dislocations etc.) due to non inclusion of the basic mechanics. In this study, a structural optimization based pelvic design is presented for an efficient pelvic prosthesis by including the effect of muscles under single leg stance. The single leg stance loading condition is divided into four categories, (a) all muscles, (b) lower muscles, (c) upper muscles and (d) average value of the muscles for entire stance phase. Thereafter, topology optimization is used to generate four prosthesis for pelvic reconstruction. Titanium alloy (Ti6Al4V) is used to design the pelvic prosthesis. The optimal designs are compared with the natural pelvic bone by measuring the shape similarity index. Results show that the stress and displacement produced by the optimal designs are less than the natural pelvic bone. The induced peak stresses in the optimal designs are low, within linear elastic zone and below the yield strength of the alloy. The moderate to good shape similarity values indicate less complications such as dislocations, stability and constraining the range of hip joint.

Pelvic floor disorders such as urinary incontinence, fecal incontinence, and pelvic organ prolapse represent a major public health concern in the United States affecting one third of adult women [1]. These disorders are determined by structural and mechanical alterations of the pelvic organs, their supporting muscles and connective tissues that occur mainly during pregnancy, vaginal delivery, and aging [1].
