Resumo:

Individuals with stroke have neuromuscular weakness or paralysis on one side of the body caused by some muscles disengaging and overexciting other muscles. Hyperextension of the knee joint and complete lack of plantar flexion of the ankle joint are common symptoms of stroke. This thesis encompasses the simulation of hemiparetic function using both a knee orthosis with variable impedance, specifically in terms of stiffness and damping, and the Proprioception Interference Apparatus. The section regarding the knee orthosis with variable impedance focuses on the creation and implementation of a small, lightweight, and adjustable orthotic device to be positioned around the knee of an able-bodied person to simulate hemiparetic gait. Force and range of motion data from able-bodied subjects fitted with the orthosis, inducing hemiparetic gait, was collected using the Computer Assisted Rehabilitation ENvironment (CAREN) system. The four parameters that the design focused on are damping, catch, hysteresis, and stiffness. The main goal of the project was to discern whether this device could be utilized as a viable research instrument to simulate hemiparetic gait. It was hypothesized that the device has the potential to be utilized in the future as a research device to be used on able-bodied persons to study asymmetries in gait and eventually quantify the Modified Ashworth Scale. It was also believed that it could serve as a possible rehabilitation device for people with stroke since it has been designed to induce larger knee flexion as an after effect. However, this would require the proper clinical evaluation and experimentation procedures to be successfully concluded. A comparison between how the dominant leg was affected by the orthosis and how the non-dominant leg was affected was investigated as well. The results show that the device affected the velocities, knee angles, and force profiles of the subject’s gait. The second section involving the Proprioception Interference Apparatus involved the creation and implementation of a haptic apparatus that utilizes vibration as well as transcutaneous electrical nerve stimulation (TENS) in various combinations with and without visual feedback to induce a proprioceptive illusion around the knee joint, as if a subject has a version of hemiparesis. The main goal of the project was to discern whether a device of relatively the same design could be utilized as a viable research instrument to simulate stroke-like balance in able-bodied subjects. Comparison between how the root mean square (RMS) values of each marker location, the average of the standard deviations of the forces, and RMS of the center of pressure affected the various conditions was investigated as well. It was hypothesized and concluded that the RMS values and average of the standard deviations when subjects had no visual feedback would have a significant difference from when they had visual feedback. It was also hypothesized that Proprioceptive Interference Apparatus (PIA) would have a significant effect on the RMS and standard deviation values since it was meant to disrupt the motor control function of the knee, however, this was proved false after data analysis. It was also surmised that the application of the TENS had more of an effect on the RMS and standard deviation values, whether it was used on its own or in combination with the vibrations, than the vibration stimulation alone. However, once again, this was not statistically significant.

The purpose of this study was to investigate the effects of Swiss ball training on (1) knee joint reposition sense (knee proprioception), (2) core muscle strength and (3) dynamic balance in sedentary collegiate students. In this thesis, two different participant groups and two different training methods were used. In order to evaluate the effect of Swiss ball training on knee proprioception and core strength, 3 days per week training was conducted throughout 10 weeks (Study 1). In order to evaluate the effect of Swiss ball training on dynamic balance, 2 days per week training was conducted throughout 10 weeks (Study 2). 60 sedentary university students participated in Study 1. 47 sedentary university students participated in Study 2. The results of the study indicated that Swiss ball training has significant effect on knee proprioception and core muscle strength. For dynamic balance, at the end of the 10-week Swiss ball training, in both groups (Swiss ball and control), dynamic balance scores were improved significantly. Therefore, effect of the Swiss ball training on dynamic balance could not be determined. As a conclusion, an instability training program using Swiss balls with body weight as resistance can provide prolonged improvements in joint proprioception and core strength which would contribute to general health and performance.

Metodologia: Pesquisa computorizada nas bases de dados PubMed, PEDro e Web Of Science, utilizando a expressão de pesquisa: “Whole-Body Vibration” AND Proprioception AND Knee. Resultados: 6 estudos cumpriram os critérios de elegibilidade definidos, tendo apresentado resultados para uma amostra total de 136 indivíduos. Em indivíduos sem patologias, verificaram-se efeitos significativos da VCI na proprioceção do joelho quando efetuada a frequências intermédias (35Hz) num nº de séries igual ou superior a 4 e amplitude de 2mm, assim como em frequências mais baixas (20Hz) mas com um nº superior de séries. Já em indivíduos sujeitos a reconstrução do LCA, verificam-se melhorias significativas com frequências entre 30Hz e 50Hz e amplitudes iguais ou superiores a 2,5mm. Conclusão: a VCI produz efeitos positivos tanto na proprioceção do joelho de indivíduos sem patologias como de sujeitos a reconstrução do LCA, podendo desta forma complementar os tratamentos convencionais.
Aim: To synthesize the evidence about the effect of Whole-Body Vibration (WBV) on the knee proprioception of individuals without pathologies or submitted to anterior cruciate ligament (ACL) reconstruction. Methodology: Computerized search in the PubMed, PEDro and Web of Science databases using the expression: “Whole-Body Vibration” AND Proprioception AND Knee. Results: 6 studies met the defined eligibility criteria and presented results for a total sample of 136 individuals. In individuals without pathologies, there were significant effects of WBV on knee proprioception when performed at intermediate frequencies (35Hz) with a number of series equal to or greater than 4 and amplitude of 2mm, as well as at lower frequencies (20Hz) but with a higher number of series. In individuals submitted to ACL reconstruction, significant improvements are reported with frequencies between 30Hz and 50Hz and amplitudes equal to or greater than 2.5mm. Conclusion: WBV produces positive effects both in the knee proprioception of individuals without pathologies as in subjects submitted to ACL reconstruction, thus it can complement conventional treatments.

The purpose of this study was to display increase in eccentric hamstring strength after 10-weeks training program. Secondly, if such an increase occurred, would this strength change result in altered landing kinetics and improved jumping performance? 27 recreational female athletes assigned into experimental (n = 14) and control (n = 13) groups. Baseline measures of landing kinetics were collected using a force plate, strength data and proprioceptive measurements were evaluated using an isokinetic dynamometer and vertical jump performance were determined by a jumping mat. Results indicated that NHST group increased their eccentric hamstring strength after eccentric strength training program (week-1 = 233.6±
27.5, week-10 = 253.8±
28.4 Nm/kgbw

0.0 &
week-10 = 0.27±
0.0 cm
p<
.01). This study supported the following points: 1) increases in the eccentric hamstring strength were evident after NHST program, 2) the increases in isokinetic strength were sufficient to cause alterations in landing kinetics to decrease the applied joint forces, so the NHST program would be an influential factor in decreasing the lower extremity injuries, and 3) the increase in the efficiency of force transfer at the final take off phase of jumping contributed to a higher performance in vertical jump.

Iščašenje, luksacija ili dislokacija čašice (patele), predstavlja povredu kolena prilikom koje dolazi do pomeranja patele iz patelofemoralnog dela zgloba kolena. Pri ovoj povredi dolazi do oštećenja medijalnih mekotkivnih struktura kolena koje su zadužene za pravilno pomeranje čašice unutar patelofemoralnog zgloba. Nakon prve povrede kod velikog borja pacijenata razvije se hronična nestabilnost patelofemoralnog zgloba sa posledičnim recidivantnim luksacijama patele. Mehanizam nastanka hronične nestabilnosti nije u potpunosti razjašnjen i smatra se multifaktorijalnim, a za jedan od faktora smatra se narušavanje neurološke regulacije pokreta kolena. Propriocepcija je složen neurološki mehanizam koji nam omogućava mentalno mapiranje delova tela, sprečavajući prekomerne i nepravilne pokrete koji mogu dovesti do povređivanja. Za njegovu procenu u zglobu kolena najčešće se procenjuje osećaj pozicije zgloba (JPS – eng. „Joint Position Sense“) kao jedne od komponenti propriocepcije. Nerazjašnjeno je koji je najbolji način za njegovu procenu u pogledu izbora različitih uglova fleksije kolena i pozicija ispitanika, ali i kakav je uticaj povreda struktura kolena na njega. U istraživanju su učestvovale isključivo osobe ženskog pola (15-17 godina), svrstane u tri kategorije od po 30 ispitanika. Prvu, kontrolnu grupu, činile su zdrave ne sportistkinje; drugu, grupu sportistkinja, činile su ispitanice koje su se takmičarski bavile košarkom; treću, grupu pacijentkinja, činile su osobe sa luksacijom čašice kolena. Za merenje JPS korišten je VICON optički sistem (©Vicon Motion Systems Ltd. UK registered no. 1801446) za analizu pokreta. Za svaku grupu meren je JPS metodom pasivnog pozicioniranja-aktivne reprodukcije sa kolenom u različitim nivoima fleksije (30°, 45° i 60°), u uspravnom, ležećem i sedećem položaju, nakon čega su rezultati bili poređeni između grupa. Naši rezultati su pokazali da odabir pozicije ispitanika i ugla merenja ne utiče na JPS u zdravim populacijama, kontrolnoj grupi i grupi sportiskinja, niti postoji statistički značajna razlika odgovarajućih pozicija i uglova između ovih grupa. Za grupu pacijentkinja dobili smo da postoji deficit propriocepcije, i da je sedeći stav najosetljivijim za procenu deficita osećaja pozicija zgloba kolena. U odnosu na odgovarajuće uglove kontrolne grupe i grupe sportistkinja, kod pacijentkinja postoji statistički značajno veća greška traženih uglova u sedećem stavu, zbog čega je ovaj stav karakterističan za ovu grupu. Takođe smo uočili da je najveća razlika pri uglu od 45°, čineći ga kritičnim uglom za grupu pacijentkinja. Ono što je ključni zaključak je da nakon povrede kolena po tipu luksacije čašice postoji neurološki deficit kontrole pokreta kolena, koji potencijalno može dovesti do daljeg povređivanja. Obzirom da je JPS metod kumulativne procene proprioceptivnog sistema, dalja istraživanja bi trebala da budu usmerena na određivanje mesta oštećenja istog, čime bi se postiglo bolje razumevanje funkcionisanja sistema regulacije pokreta kao i mogućnost sprovođenja efikasnijeg lečenja nakon povrede kolena.
Patellar dislocation represents a knee injury during in which patella moves outside patellofemoral joint. The injury causes damage to the medial soft tissues of the knee, who act as a lateral patella restraint. After the first patella dislocation, large number of patients develop chronic instability of patellofemoral joint with recurrent patella luxation as a result. Etiology of chronic instability of patellofemoral joint is not fully understood, and is considered multifactorial, with one of the factors being the impairment of the neurological regulation of the knee movement. Proprioception is a complex neurological mechanism that allows us to mentally map parts of the body, preventing us from excessive and irregular movements that can lead to injuries. Measuring joint position sense (JPS) is the most commonly used method for evaluating proprioception of the knee. It is unclear what is the best way to evaluate JPS in terms of choosing different angles of knee flexion and the position of subjects, as well as the impact of different knee injuries on it. This study included only female participants (15-17 years old), who were classified into three groups of 30 subjects. The first, control group, included healthy non-athletes; second, a group of athletes, included subjects who actively participated in basketball; third, group of patients, consisted of people with a luxation patella. For measuring JPS, a VICON optical system (© Vicon Motion Systems Ltd. UK registered No. 1801446) was used for motion analysis. For each group, JPS was analysed using passive positioning-active reproduction method with knee at different angles of flexion (30°, 45° and 60°), in an upright, lying and seated position, after which the results were compared between the groups. Our results had shown that the choice of position and angle of measurement did not affect JPS in healthy populations, control group and group of athletes, nor there is a statistically significant difference in the respective positions and angles between these groups. For patients group, we observed a deficit in proprioception, and that the sitting position was the most sensitive for assessing this deficit of JPS. In relation to the corresponding angles of the control group and the athletes' group, there were statistically significant errors of the reproduction angles in the sitting position, which is why this position is characteristic for patients with patella dislocation. We also noted that the biggest difference was for 45° angle, making it the critical angle for the patient group. The key conclusion is that after knee injury, such as patella dislocation, neurological deficit of knee movement control can be observed, and which can potentially play a role in further injuries. Since measuring off knee JPS is a method of cumulative assessment of the proprioceptive system, further research should focus on determining the exact site of damage, which would allow for better understanding and more efficient treatment of knee injuries.

Projeto de Graduação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Licenciada em Fisioterapia
Objetivo: Determinar o efeito da fadiga muscular no Senso de Posição Articular (SPA) do joelho e comparar acuidade propriocetiva entre amplitudes de teste, membro preferido e não-preferido e entre géneros. Métodos: Participaram neste estudo 33 adultos saudáveis. A fadiga foi induzida através do levantar e sentar de uma cadeira. O SPA foi avaliado pelo método de reposicionamento ativo, para as posições de 20º e 45º de flexão, através de um sistema de centrais inerciais. Resultados: O erro de reposicionamento aumentou com a fadiga aos 45º no membro preferido (p=0.030). O erro de reposicionamento é maior aos 45º do que aos 20º, com diferenças significativas no membro não-preferido (p=0.018) antes da fadiga e no membro preferido (p=0.020) depois da fadiga. A dominância não influenciou o SPA em repouso, mas depois da fadiga o membro preferido apresentou erros de posicionamento superiores na amplitude de 45º (p=0.039). Não existem diferenças relacionadas com o género (p>0.05). Conclusão: A fadiga afeta o SPA. O erro de reposicionamento é maior em amplitudes intermédias do que em amplitudes extremas. O membro preferido é mais afetado pela fadiga e não existem diferenças no SPA inerentes ao género.
Aim: To determine the effect of muscle fatigue on knee joint position sense (JPS) and compare the proprioceptive acuity between test amplitudes, dominant and non-dominant limb and genders. Methods: The sample consisted of 33 healthy subjects. Fatigue was induced by a sit to stand task. JPS was evaluated by active repositioning method, to the ranges of 20º and 45º of flexion, using a central inertial system. Results: Reposition error increased with fatigue at the range of 45º in the dominant limb (p=0.030). The reposition error is higher at 45º than at 20º, with significant differences in the non-dominant limb before fatigue (p=0.018) and in the dominant limb (p=0.020) after fatigue. Dominance did not influenced JPS at rest, but after fatigue the dominant limb showed higher reposition errors at the range of 45º (p=0.034). There are no differences related to gender (p>0.05). Conclusion: Muscle fatigue affects JPS. The reposition error is higher at intermediate ranges than in limit ranges. Fatigue affects mainly the dominant limb and there are no differences in the JPS between gender.

There is a big risk that neuroreceptors located in the knee, responsible for our proprioceptive ability, are damaged after an anterior cruciate ligament (ACL) injury occurs. This may cause miscommunication between the neuroreceptors and motoric function in the brain. Due to the brains plasticity, it has been shown that brain activity patterns, presented as blood oxygen dependent level-signal (BOLD-signal), achieved from functional magnetic resonance imaging (fMRI) differs between healthy and injured individuals when performing certain tasks involving knee movement. As there is little consensus on how a proprioceptive test should be performed, a unique test were participants uses blindfold during a knee bending exercise was created at U Motion Lab, Umeå University. A Matlab based general user interface (GUI) was created for evaluation of the proprioceptive test. This GUI is communicating with the third party toolbox SPM12 and performs necessary preprocessing fMRI-image steps for statistical analysis and statistical parametric mapping of the BOLD-signal for both a healthy control- and ACL-injured group. The fMRIimages preprocessed by the GUI were generated by a 3 T GE scanner and the motion data was collected using an eight-camera 3D-motion analysis system. Time events for three different tasks was investigated. These were passive resting, memorizing and proprioceptive events. For both the control (5 participants)- and ACL (2 participants) group the main area of brain activation during the proprioceptive tests occurred in the frontal lobe. For the control group, brain activation was found in the cerebellum anterior lobe which is a possible origin for unconscious proprioception. For the ACL group activation was found in the inferior parietal lobule which involves visuomotor integration. Activation was also found in the inferior frontal gyrus which according to previous studies, may indicate risk-taking/”out of character” decisions. The results of this study indicates that the proprioceptive test seems to be a promising tool for evaluation of proprioceptive ability. However, more subjects need to be included to validate the result of this study.

The purpose of this study was to investigate the effects of Nordic hamstring strength training (NHST) program on (1) leg power, (2) vertical jump, (3) and knee proprioception measurements of 10-12 years old male basketball players. Nordic Hamstring Strength Training (NHST) group (N=16), participated in basketball training plus in Nordic hamstring strength training, while the control group (N=11) participated in basketball training only. Subjects were tested before and after 5-week training program for, vertical jump, isokinetic leg strength and knee proprioception. Each subject who agreed to participate in this investigation signed a consent form along their parent. Pre and post test differences between experimental and control group was investigated by MANOVA and paired sample t-test was used to evaluate the differences between pre and post tests of both groups. There was no significant difference in pre and post test results of NHST and control group. There were statistically significant increase in concentric quadriceps and hamstring strength, eccentric quadriceps strength, conventional H:Q strength ratio, and vertical jumping measurements in experimental group between the pre and post tests. It can be concluded that NHST program combine with basketball training has beneficial effects on the leg strength and H:Q strength ratio. These findings also suggest that hamstring exercise may be beneficial or helpful for preventing the hamstring injury occurrence and improving the physical performances such as jumping ability.

Ova studija je bila prospektivnog karaktera. Uz dopuštenje etičkog komiteta Kliničkog centra Vojvodine istraživanje je sprovedeno na Klinici za ortopedsku hirurgiju i traumatologiju i obuhvatilo je 60 pacijenata muškog pola, koji su metodom slučajnog izbora na randomizirani način uključeni u ispitivanje, a koji se aktivno i profesionalno bave fudbalom, košarkom ili odbojkom, primljenih na Kliniku za ortopedsku hirurgiju radi artroskopske rekonstrukcije pokidanog prednjeg ukrštenog ligamenta. U ispitivanje su uključeni samo oni pacijenti koji su dali potpisani informisani pristanak da učestvuju u ispitivanju, koji su zadovoljii sve kriterijume za uključivanje i koji nisu imali niti jedan kriterijum za isključivanje iz studije. Kriterijumi za uključivanje u studiju podrazumevali su sledeće: da je pacijent primljen na Kliniku za ortopedsku hirurgiju i traumatologiju Kliničkog centra Vojvodine u Novom Sadu radi operativnog lečenja prekida prednjeg ukrštenog ligamenta kolena, da je potpisao informisani pristanak za uključivanje, da je starosne dobi od 18 do 45 godina, da se aktivno i profesionalno bave fizičkom aktivnošću regulisanom pravilima (fudbal, odbojka, košarka). Kriterijumi za isključivanje pacijenata iz istraživanja bili su sledeći: prisustvo udružene povrede i spoljašnjeg pobočnog ligamenta koja zahteva operativno lečenje, pojava težih opšte – hirurških komplikacija, želja pacijenta da bude isključen iz daljeg ispitivanja, bez obaveze da tu svoju odluku obrazloži. U prvoj fazi konstruisan je aparat, digitalni goniometar, uz pomoć kojeg je urađen eksperimentalni deo ovog ispitivanja i napravljena je baza podataka sa poljima za upis deskriptivnih i antropometrijskih parametara. Potom je uz pomoć aparata svim ispitanicima testirana sposobnost propriocepcije (JPS). Testiranje je obavljeno preoperativno na povređenom i nepovređenom ekstremitetu, u dva maha: odmah po zadavanju ciljnog ugla od 35° i nakon 5 minuta. Druga faza je obavljena minimum 6 meseci nakon operativnog lečenja, hirurškom, artroskopskom rekonstrukcijom pokidanog prednjeg ukrštenog ligamenta kost-tetiva-kost tehnikom (bone-tendo-bone, BTB). Klinički pregled svakog pacijenta je podrazumevao proveru rezultata Lachman testa (pozitivan/negativan), Lysholm i IKDC bodovne skale za koleno i to preoperativno a potom i tokom postoperativnog kontrolnog pregleda. Po uzoru na mnoge sajtove renomiranih ortopedskih organizacija (http://www.orthopaedicscore.com/), naparavljen je on-line upitnik na Google drive-u gde su u elektronskom obliku prikupljani podaci za skale koje smo koristili. Dobijeni rezultati su za svaku skalu ponaosob potom prebacivani u Excel i dalje obrađivani adekvatnim statističkim alatkama u adekvatnom programu. U rezultatima je uočeno da dobijena razlika u preciznosti pozicioniranja potkolenice sa oštećenim ligamentarnim aparatom kolena u odnosu na nepovređenu nogu pre hirurške rekonstrukcije prednjeg ukrštenog ligamenta ne pokazuje statistički značajnu razliku. Međutim, postojala je statistički značajna razlika u brzini kojom se postiže zadati ugao, tj. povređena noga imala je veći intenzitet ugaonog uspona što ukazuje na kvalitativne razlike u samom obrascu pokreta. Takođe, na ovom uzorku dobijeno je da postoji statistički značajna razlika u preciznosti pozicioniranja potkolenice sa oštećenim ligamentarnim aparatom kolena u odnosu na nepovređenu nogu nakon hirurške rekonstrukcije prednjeg ukrštenog ligamenta tj. pacijenti su nakon rekonstrukcije statistički značajno »prebacivali« zadatu vrednost od 35°. Test pozicioniranja ekstremiteta za ovo ispitivanje konstruisanim aparatom se pokazao kao senzitivna i specifična dijagnostička procedura gubitka sposobnosti propriocepcije usled kidanja prednjeg ukrštenog ligamenta.
In this prospective study examined group consisted of 60 male patients with an anterior cruciate ligament tear and all participants were at the time before injury actively playing afootball, basketball or volleyball. The study was conducted at the Clinic for Orthopaedic Surgery and Traumatology Clinical Center of Vojvodina in Novi Sad where participants were admitted for arthroscopic ligament reconstruction. All participants were informed of the study by their clinicians and gave written consent. Thee exclusion criteria were the following: occurrence of combined cruciate ligament with lateral collateral ligament injury that required surgical treatment; occurrence of more serious general surgical complications; the patient’s wish to be excluded from further research without an obligation to give any further explanation to his decision. In the first stage of the study, an apparatus called digital goniometer was constructed, which was used to conduct the experimental part of the study, and a database with fields for inserting descriptive and anthropometric parameters was made. Next, by using the apparatus, all subjects were tested for proprioception ability (JPS). The tests were performed preoperatively on the injured and the uninjured limb in two instances: straight after determining the target angle of 35° and 5 minutes afterwards. The second stage was performed postoperatively in the same maner, following a minimal 6-month period after a surgical arthroscopic reconstruction of the torn anterior cruciate ligament by bone-tendon-bone (BTB) technique. The clinical evaluation of each patient involved Lachman test (positive / negative), Lysholm and IKDC scales, first pre-operatively and then during post-operative check up assessment. Following the example of many websites or eminent orthopaedic organisations (http://www.orthopaedicscore.com/), an online survey was made on Google Drive, where data was collected electronically for the scales used. The results were then transferred to Excel for each scale, to be further processed by using adequate statistic tools in an adequate programme. The results indicated that, when compared with the uninjured leg, a resulting disparity in precision of positioning the lower leg with a damaged ligament apparatus of the knee before the surgical reconstruction of the anterior cruciate ligament was not considered statistically significant. However, there was a statistically significant difference in the speed of attaining a specified angle which indicates qualitative differences in the motion pattern itself. Furthermore, this sample study resulted in a statistically significant difference in the precision of positioning of lower leg with the damaged knee ligament apparatus after the surgical reconstruction of the anterior cruciate ligament, when compared with the uninjured leg, i.e. after the reconstruction, the patients had a significantly higher degree of flexion than the targeted 35°. The test for positioning extremities, performed with the specially constructed apparatus, proved to be a sensitive and specific diagnostic procedure for determining the loss of proprioceptic ability due to anterior cruciate ligament tear.

Les gonalgies et les aponévrosites plantaires représentent la majorité des motifs de consultations d’un cabinet de podologie. Les patients souffrant de ces pathologies ressentent des douleurs au niveau du genou ou du pied qui peuvent être invalidantes. Bien que le port d’orthèses plantaires représente un traitement conservateur efficace, la prescription de ce traitement repose sur une connaissance empirique des effets de ce dernier. Le but de ce travail était donc d’étudier les effets des semelles orthopédiques à dominante biomécanique (modifiant la posture) ou proprioceptive (stimulant les capteurs de la sole plantaire) sur les modifications de la stratégie neurale chez les patients souffrant de ces pathologies et de déterminer quels pouvaient être les liens avec la diminution de la douleur ressentie. Pour cela, nous avons procédé à une évaluation de la douleur, un examen de la marche, un examen stabilométrique et des enregistrements électrophysiologiques (réflexes mesurés au repos et lors d’une contraction musculaire volontaire). L’évolution de ces différents paramètres a été mesurée après trois, six et neuf semaines de port d'orthèses plantaires. Les résultats obtenus ont été comparés à ceux recueillis chez des patients témoins indemnes de toute pathologie.Même si les résultats obtenus lors de ces études ne sont pas aussi concluants que nous l’aurions souhaité et que de nombreuses questions restent encore en suspend, ce travail a permis toutefois d’ouvrir au domaine de la podologie un champ de recherche jusque-là peu ou pas exploré
Knee pain and plantar fasciitis represent most of the reasons for consultation of a podiatrist. Patients with these pathologies experience knee or foot pain that can be disabling. Although the use of foot orthoses is an effective conservative treatment, its prescription is based on an empirical knowledge of its effects. The aim of this study was to investigate the effects of foot orthoses based on biomechanical (modifying the posture) or proprioceptive (stimulating sensors of the plantar sole) principles on neural strategy changes in suffering patients and to determine the links with the decrease in perceived pain. For this, we performed a pain assessment, walking and stabilometric examination and electrophysiological recordings (reflexes measured at rest and during voluntary muscle contraction). The evolution of these different parameters was measured after three, six and nine weeks of wearing foot orthoses. The results obtained were compared with those obtained in control patients free from any pathology.Although the results of these studies are not as conclusive as we would have liked and many questions remain unresolved, this work has opened up to the podiatry a field of research until then little or not explored

【Background and purposes】Proprioception is the sensation originating from the mechanoreceptors around joint, skin, and muscle. The functions of proprioception are important, since it provides the awareness of position and movements of joints in space. Many factors affect proprioception. Aging, fatigue, injury, disease, and cryotherapy deteriorate proprioception; while warm-up, training, repeated passive motion enhance it. Previous studies on active warm-up revealed its effect of improving proprioception, likely via ways including elevation of tissue temperature and repeated mechanical stimulations. Studies also revealed the suppressing effects of cryotherapy on proprioception, however, limited information is available for the effects and mechanisms of tissue temperature elevation on proprioception. This study thus aimed to verify the effects of warm-up and passive repetitive motions effectors, and underlying mechanisms of temperature factor, by comparing the effects of physical activity, heating and repeated passive motion effect of proprioception, to further understand the underlying mechanisms. 【Method】We employed a cross-sectional and repetitive measurements design. Twenty healthy subjects participated in the experiment. Treatments were randomly applied in three successive days. Proprioception was tested before and immediately following the three treatments.【Result】After the warm-up intervention, no significant effect on knee proprioception was found. After the physical activity, kinesthesia error increased on knee flexion 70°(from 2.42 ± 1.48° to 3.68 ± 1.86°). After the heating, joint position sense error increased on knee flexion 70° (from 1.15 ±1.3° to 1.56 ± 1.43°). After the passive repetitive motions, no significant effect on knee proprioception was found.【Conclusion】No significant effect of warm-up on knee proprioception was found.【Clinical Relevance】This study provides insights the understanding of how knee proprioception changes following active warm-up, short-wave, and repeated passive motions, as well as the related mechanisms.

The purposes of this research are 1) to establish a new reliable assessment method for proprioceptive function of knee joint in clinical use, 2) to assess the propriopceptive function of the total knee replacement （TKR）patients and 3) to exam the relationship of proprioception and ambulating function. There were 16 TKR patients and 16 aged matched control group in this study. Two assessment model for propriocetive function — unilateral and bilateral model were used, and subjects were test with active method and passive method separately. In data analysis, the constant error, variable error, and root mean square error were used.. Result showed that the proprioceptive function of the TKR patient was poor, and the walking velocity was slower than aged matched control group. There was no correlation between propriocpetion and walking speed in the TKR patients. Finding of this study supports that the proprioceptive function of patient after TKR is decreased. Further research is needed to exam the influence of the diminished proprioceptive function on the functional performance of TKR patients.

Background: Proprioception is the perception of joint and body movements, as well as body or body segments positions, in space. It is provided primarily by joint mechanoreceptors, superficial receptors, and muscle afferents. Proprioception may be affected by many factors such as age, gender, disease, exercise, and fatigue. Up today, the mechanisms or pathways by which fatigue influences proprioception have not been elucidated. Generally, it is well accepted that local muscular effects occur during fatigue may negatively affect proprioception. It has been proposed that in addition to the metabolic acidosis resulting from actively muscle works, stretching and laxity of the joint resulted from the repetitive joint movements might also reduce proprioception. So far, little direct evidence or research supports this hypothesis. Purpose: This study aimed to examine the effects of fatigue exercise and repetitive passive motions (RMP) on knee proprioception. Method: We employed a pretest-posttest control group design and used two active repositioning methods to measure knee proprioception before and following a fatigue exercise and a repetitive passive motion intervention. Result: Study results showed a statistically significant increase in absolute repositioning error following the fatigue exercise, and a decrease following the RPM intervention. Conclusion: This study demonstrated that a RPM protocol (120°/s over a 10°~100° range, 60 rep) was capable of improving knee joint position sense. Meanwhile, the negative effect form the muscle receptors following the fatigue exercise overwhelmed the positive effect from the RPM intervention. Clinical relevance: This study supports the clinical utilization of RPM to promote proprioception. In addition, this study suggests routines of dynamic joint movements before exercise and sports to better enhance the warm-up effects, than merely using heat pack or hot bath.

Therapeutic exercise is important to patients with knee osteoarthritis. Few studies reported the effect of therapeutic exercise in proprioception for these patients. The purposes of this study were to investigate the train-ing effect of sling suspension exercises, as a proprioception-training tool, for patients with knee osteoarthritis and further, to build up an model of pro-prioception training. Twelve subjects were recruited in this study. The inclusion criteria were aged 50 to 70, both genders, diagnosed as knee osteoarthritis, grading 2 or 3 in Kellgren’s scale. After having their consents all subjects received baseline measurements including active joint reposi-tion test, functional ambulating test and self-evaluating with Western Ontario & McMaster Universities Arthritis Index (WOMAC). Then they were randomly assigned to training group and reference group. Seven subjects in the training group received the treatment of heat, interferential current (IFC), and sling suspension exercises or just only sling suspension exercises. Five subjects in the reference group received the treatment of heat and IFC or no intervention. The training sessions of sling suspension exercises were 3 times per week, lasting for8 weeks. After 8-week training, both groups were given post-test which is completely the same as pre-test. Mann-Whitney U Test was used to test the difference between groups, and Wilcoxon Signed Ranks Test was used to test pre-post difference in both groups. The results showed it was no difference between both groups in all the measurements of pre-test. After 8 weeks, it showed significant difference on joint reposi-tion test (p<.05) but no difference on functional ambulating test and WOMAC index (p>.05) between the 2 groups. In the training group, all mea-surements got significant improvement (p<.05) except one of the functional ambulating tests. However, the reference group only showed significant improvement in pain and physical function subscales of WOMAC (p<.05). This study concludes that the sling suspension exercises designed for patients with knee osteoarthritis improve the proprioception of knee joint. The con-tent and concept of sling suspension exercises in this study might be a refer-ence of proprioception training for patients with knee osteoarthritis. Increasing case number and elongating the duration of intervention are suggested in further studies.

Background and Purpose: Proprioception is the perception of joint and body movement in space. It may be affected by many factors such as gender, age, temperature, injury or disease, effusion, or exercise. For exercise, the exercise mode, duration, dose, and frequency also influence proprioception. In addition, the movement velocity and passive joint motion may also affect proprioception. Recent studies showed that repeated passive motion in slow speed not only recovered joint range of motion, but also improved proprioception. However, the effects of repeated passive motion in functional speed, such as walking or running, on knee proprioception remain unclear. Therefore, this study aimed to determine the influences of repeated passive motion of various angular velocities on knee proprioception. Methods: Sixteen healthy young adults (22.13±2.63 yr; 8 males and 8 females) participated in this study of repeated measured design. Active repositioning and kinesthesia tests measured knee proprioception before and after repetitive passive motion interventions of 4 angular velocities－0º/s、2º/s、90 º/s、150 º/s－in four successive days. Result: Analyses showed great test-retest reliability for the same day (ICC=0.984~0.996) and pre-tests over four days (ICC=0.934~0.948). Passive motion interventions of 90º/s and 150º/s both caused significant improvements in knee proprioception; while interventions of 0º/s and 2º/s failed to show any significant change. Conclusions: The repeated passive motion of functional angular velocities better improved knee proprioception. Clinical Relevance: This study contributes to 1) the understanding of how knee joint proprioception changes during repeated passive motion of various velocities, 2) finding the optimal velocity and 3) discussing the related mechanism. Furthermore, this study suggests that high-speed repeated passive motions is of great potential for clinical practice to improve proprioception.

The amputee patients accompany with muscle power insufficient and proprioception losing because their knee joint construction and major muscle fascicle which control knee flexion or extension were cut. Therefore, amputee patients need to swing their stump to make knee joint flexion or extension. These repeated motions could not swing to target knee angle stably and precisely. In this study, in order to breakthrough these drawbacks, a prosthesis system with power assisted, mechanism design, proprioception compensation was developed and verified. There were static functional verification and dynamic functional verification in this study. In the static functional verification, the linear ruler was used to measure the stroke of actuator developed in this study. Besides, the digital level meter was used to assess the angle control verification. These measured results were compared with targeted values. The mean error of stroke was 0.023±0.175mm, and the mean error of angle was 0.005±0.074°. In the dynamic functional verification, the proprioception compensation and coordinate control modules were considered in the level walking experiments, the differences between affected side and unaffected side were used to evaluate the coordinate control efficiency. The mean maximum flexion angle error was 0.748±0.898° and the percentage error was 1.968%. In addition, the mean delay time was 0.025±0.022 seconds. The experimental results showed that the amputee system developed in this study could provide coordinate level walking for amputee.

Background and Purpose: The issues relating elderly are becoming more and more important. Investigations revealed there is a high rate of the elderly falling, which may result from weakening musculoskeletal supports and poor balance. Studies have showed the close relationship between poor balance and proprioception, which represents the unique perception of joint positions and body movements in space. Many factors such as age and exercise influence proprioception. Recent studies indicated that rapid continuous passive motion (RCPM) can improve proprioception on healthy adults, however, its effects on healthy elderly are unknown. Furthermore, RCPM was performed by isokinetic dynamometer in previous studies. It is still not clear if RCPM is still capable of improving proprioception when provided by other similar but sampler machinery. Therefore, this study aimed to determine the influences of RCPM on knee proprioception and balance in healthy elderly, and compare the efficacies of a dynamometer and a knee joint CPM machine. Methods: Twelve healthy elderly and twelve healthy adults were recruited and underwent proprioception and balance measurement before and after RCPM (90 degrees/s) interventions provided by the two machines. Result: Dynamometer and knee joint CPM machine both showed significant improvements on knee proprioception in healthy elderly and young people. The efficacies of the two interventions were similar. As for balance, both interventions did not affect most one-leg standing tests. Conclusion: Rapid continuous passive motion can significantly improve knee proprioception in healthy elderly and young, but can not significantly improve one-legged stance balance, despite provided by isokinetic dynamometers or knee joint CPM machines. Clinical Relevance: This study suggests the elderly to utilize RCPM for promoting knee proprioception. For example, the elderly can utilize RCPM before exercise for increasing safety. In addition, inclusion the content RCPM in the rehabilitation settings and general sport practice is also encouraged.

Purpose: The objective of this study was to understand the effectiveness of Self Myofascial Release by using foam roller (FR) as a recovery tool after exercise- induced muscle soreness. The muscle soreness, active angle reproduction and muscle stiffness were used to evaluate the effects of the application of Self Myofascial Release. Methods:Twenty male subjects (no exercise habit) were randomly assigned into the control (n = 10) or FR (n = 10) group. All the subjects followed the same testing protocol.The subjects received six testing sessions:1) pretest measurements,eccentric exercise,2) POST-0 measurements,and along with measurements at 3) POST- 30min, 4) POST-24, 5) POST-48, and 6) POST-72. The only between-group difference was that the FR group performed a 3-min FR exercise protocol at the began of each testing session (POST-30, POST-24, POST-48 and POST-72). A two factor ANOVA (treatment × time) with repeated measures was used for each dependent variable. Results: Self Myofascial Release substantially reduced active angle reproduction while reducing muscle soreness ( p < .05). Self Myofascial Release showed no substantial between-group differences ( p < .05) for muscle stiffness measurements. Conclusion: The most important findings of the present study were that Self Myofascial Release was beneficial in reducing active angle reproduction error while attenuating muscle soreness in comparison with the control group. There were no substantial muscle stiffness between-group differences while there was a tendency that Self Myofascial Release reduced muscle stiffness at 30min, 24, 48 and 72 hours compared with the control group, indicating that Self Myofascial Release may is beneficial to the impaired proprioception function after exercise-induced muscle soreness.

Neuromuscular training (NT) is a kind of exercise drill to improve the coordination and performance in sports. The purpose of this study was to evaluate the effects of 6-weeks NT on knee joint proprioception and landing force in female basketball Amateurs. Twenty-Four female basketball amateurs were assigned into NT or control groups by volunteer. All the players were underwent regular basketball practice, 90 minutes, 3 times per week for 6 weeks, but the NT group underwent extra NT which was combined with plyometric and core training, 50 minutes, 3 times per week for 6 weeks during this period. Knee proprioception was measured as joint position sense (JPS) in weight bearing (body weight) and non-weight bearing (sitting) situations at knee flexion 20°, 45° and 60°. A 30-cm high box, AMTI force plate (1500 Hz) and Noraxon system were used for the data collection.The subjects stood on their dominant legs on the box and then drop landed on the force plate during the measurement. Analysis of covariance (One-way ANOVA) was used to compare the different change between groups before and after training for each parameter, the statistic significance was set at α = .05. After training, there was a significant differences at 45° test angle in weight-bearing test (F = 6.74, p＜.05), 45° test angle in dominant leg non-weight-bearing test (F = 4.41, p＜.05). The PLF was significantly decreased (F= 5.07, p＜.05; F= 4.86, p＜.05) and the ROM was significantly increased after training. It is conclude that 6-weeks NT can improve the knee joint proprioception and landing force in female basketball amateurs.

Background and purpose: The 6-minute walk test had been used to assess the functional capacity in patients with cardiopulmonary disorders. Recently, the 6-minute walk test has popularly been used as a simple tool to evaluate patients’ aerobic capacity in patients with peripheral vascular disease, neurological disease, and musculoskeletal disorders. However, few literatures report the correlation between the 6-minute walk distance and commonly evaluated variables, such as muscle strength, endurance, standing balance…etc., as we assess patients with musculoskeletal disorders. The purpose of this study, therefore, is to investigate the correlations between the 6-minute walk distance and neuromuscular parameters, including knee proprioception (joint position sense), standing balance, and muscle function (including muscle strength and muscle endurance). Methods: 90 elderly volunteers were recruited. They are greater than 65 years old without any walking, cardiopulmonary or neurological disorders. All of them received the following assessments: knee reposition sense by closed chain in active-active test mode; one leg standing balance test (open and close eyes for 30 seconds); ankle muscle torque of dorsi-flexor and plantar flexor at 30º/s and 120º/s angular velocities; knee muscle torque of extensor and flexor at 60º/s,120º/s and 180º/s angular velocities; and knee muscle endurance at 180º/s, in addition to 6-minute walk test. Results: The correlation (r value) between the 6-minute walk distance and age, height, one leg standing balance, ankle muscle torque and knee muscle torque was to be -0.45, 0.34, 0.52-0.60, 0.39-0.57, and 0.54-0.59, respectively. The one leg standing balance with open eyes and knee flexor muscle torque showed greater correlation with the 6-minute walk distance than other variables. Conclusion: The 6-minute walk distance is probably one of assessment tools for the standing balance and knee flexor torque in the elderly subjects.

Purpose: The purposes of this study were to compare the strength and proprioception of the knee joint after one and half minutes counter movement and squat jumping, and to compare the influence of muscle fatigue on proprioception in different knee angles after counter movement jump and squat jump. Methods: Subjects were eighteen senior high school basketball players. Different jumping protocols included one and half minutes of counter movement and squat jumping. A metronome was used to control jumping speed at 60 times/minute. Isokinetic dynamometer was used to measure quadriceps strength at speed of 60°/sec and 180°/sec. Electrogoniometer was used to measure absolute reposition errors of knee joint which represent knee proprioception. The starting angle was knee flexion 15°, the target angle was knee flexion 30°, 45°, and 60°. Results: The total work of quadriceps decreased 48% and 44% after squat jumping, 35% and 34% after counter movement jump at speed of 60°/sec and 180°/sec. Absolute reposition errors were 1.74°, 2.19°, and 1.98° before squat jumping, and 4.58°, 5.95°, 8.46°, after squat jumping for knee flexion 30°, 45°, 60°. Absolute reposition errors were 1.56°, 1.97°, and 2.33° before counter movement jumping, and 6.76°, 7.43°, 5.55°, after counter movement jumping for knee flexion 30°, 45°, 60°.There were significant differences of reposition errors after both jumping protocols(p＜.05). Proprioception decreased after both jumping protocols. There were significant differences of reposition errors between two jumping protocols in knee flexion 30°, 45°, and 60°(p＜.05). The proprioception of counter movement jump was worse than squat jump for knee flexion 30°, 45°, and squat jump were worse than counter movement jump for knee flexion 60°.Conclusion: Two different jumping exercises decreased proprioception due to muscle fatigue. Two jumping protocol could induce different knee proprioception performance in three different knee angles. It led to increased knee injury rates in different joint angles.

The purpose of this study was to determine the relative importance of proprioception, ligament laxity and strength, in the performance of a functional skill, in the conservatively and surgically managed subject following anterior cruciate ligament (ACL) injury. A second purpose of the study was to demonstrate differences in knee proprioception, anterior tibial displacement, quadriceps and hamstring muscle strength, and two functional performance tests among the following three groups: 1) conservatively managed following ACL rupture, 2) surgically managed following ACL rupture, and 3) uninjured controls. The experimental groups consisted of twenty subjects greater than 8 months post ACL injury (conservative group) and twenty subjects greater than 1 year post ACL surgery (surgical group). These groups were compared to twenty control subjects with no history of significant knee joint injury. Joint position sense values were obtained using the protocol of Barrett et al. (1991). Ligament laxity was tested by two anterior tibial displacement measurements using the KT1000 knee ligament arthometer. Quadriceps and hamstring concentric and eccentric peak torque was measured using a KinCom isokinetic dynamometer. Functional performance was measured with the single leg hop for maximum distance (SLHD) and timed six metre single leg hop tests (SLHT). The conservative group scored significantly worse than either of the other groups in proprioceptive inaccuracy, both anterior displacement tests (134N and maximum manual test) and both functional hop tests (SLHD and SLHT). The surgical group was not significantly different from the normal control group in either proprioceptive function or functional hop testing. The surgical group had an excellent post surgical outcome in anterior displacement tests (2.1mm), while the conservative group had a poor result (5.5mm) with the maximum manual test. There were no significant differences among groups in any of the strength measurements. Regressional analyses revealed that concentric quadriceps peak torque had a significant effect on single leg hop for maximum distance performance for all three groups. Proprioceptive acuity and anterior tibial displacement had no significant effect on SLHD in any of the three groups.

Resumo:

Introdução: O Senso de Posição Articular (SPA) dita a capacidade de compreender e reproduzir um ângulo articular, e é assegurado por mecanorrecetores cutâneos, articulares e musculares. Apesar de existir evidência de que a fadiga muscular aumenta o limiar de descarga do fuso neuromuscular, o efeito da fadiga no SPA do joelho ainda não é consensual. O objetivo desta investigação foi determinar o efeito da sobrecarga muscular aguda e crónica na acuidade propriocetiva do joelho, especificamente no SPA. Metodologia: Participaram no estudo 60 indivíduos, 29 jogadores de futebol (JF) e 31 não-praticantes de desporto (NP). O SPA do joelho do membro dominante (MD) e não-dominante (MND) foi avaliado em cadeia cinética aberta e através de reposicionamento ativo, com centrais inerciais e uma câmara de vídeo. Os efeitos agudos da fadiga sobre o SPA do joelho foram analisados em ambos os grupos antes e imediatamente após uma tarefa repetida de levantar/sentar, para as amplitudes de 20º e 45º de flexão. A sobrecarga muscular crónica foi estimada nos JF analisando a variação do SPA do joelho ao longo da época, para as amplitudes de 20º e 45º (teste de extensão), e 45º e 100º (teste de flexão). Principais Resultados: O protocolo de fadiga afetou apenas o SPA do joelho dos NP no reposicionamento dos 45º do MD (p=0.034). A acuidade propriocetiva de JF é superior à de NP (p<0.001), com os JF a sobrestimar e os NP a subestimar as amplitudes-alvo. Em JF, não se verificaram diferenças entre MD e MND (p>0.005). Pelo contrário, em NP, na avaliação em repouso o MD apresentou uma acuidade significativamente superior, tanto na amplitude de 20º (p=0.046) como na de 45º (p=0.036), mas inferior após o protocolo de fadiga aos 45º (p=0.050). Nos NP não se registaram diferenças no SPA do joelho inerentes ao género. No entanto, em JF, após a fadiga, o SPA das JF femininas foi significativamente inferior ao dos JF masculinos, tanto no reposicionamento dos 20º (p=0.041) como dos 45º (p=0.046) do MD. O SPA do joelho de JF não variou ao longo da época (p>0.005). No teste de extensão, uma acuidade propriocetiva significativamente inferior foi observada na amplitude de 45º, apenas no MND (p=0.012). No teste de flexão, a acuidade propriocetiva foi significativamente inferior aos 45º em relação aos 100º, tanto no MD (p=0.004) como no MND (p=0.001). Conclusões: A fadiga não tem efeitos agudos no SPA do joelho de JF, mas diminui o de NP. A acuidade propriocetiva de JF é superior à de NP. Os JF e NP falham as amplitudes-alvo por sobrestimação e subestimação, respetivamente. Em JF, a dominância não influencia a acuidade propriocetiva do joelho, mas em NP, o membro dominante apresenta uma acuidade superior em repouso, mas inferior em fadiga. Em repouso, não existem diferenças no SPA do joelho inerentes ao género, no entanto, quando se encontra em fadiga, o membro dominante de JF femininas apresenta uma acuidade inferior à de JF masculinos. A sobrecarga muscular crónica não faz variar o SPA do joelho de JF ao longo de uma época. A acuidade propriocetiva é inferior nas amplitudes intermédias da amplitude de movimento do joelho.
Introduction: Joint Position Sense (JPS) dictates the ability to understand and reproduce a joint angle, and it is provided by skin, muscle and joint mechanoreceptors. Although there is evidence that muscle fatigue increases the discharge threshold of the neuromuscular spindle, the effect of muscle fatigue on the knee JPS is still not consensual. The aim of this investigation was to determine the effect of acute and chronic muscle overload on knee proprioceptive acuity, and specifically in the JPS. Methodology: The sample consisted of 60 subjects, 29 soccer players (SP) and 31 individuals who didn’t practice any sports (NP). Knee JPS of the dominant (DL) and non-dominant limb (NDL) was evaluated through an open kinetic chain and active repositioning method, using a central inertial system and a video camera. Acute effects of fatigue on knee JPS were analysed in both groups before and immediately after a repetitive sit to stand task, to the ranges of 20º and 45º of knee flexion. Chronic muscle overload was estimated in the SP by analysing their knee JPS variation during one season, for the ranges of 20º and 45º (knee extension test), and 45º and 100º (knee flexion test). Main Results: Fatigue protocol only affected the knee JPS of the NP in the 45º repositioning of the DL (p=0.034). Proprioceptive acuity is higher in the SP than in the NP (p<0.001), with the SP overestimating and the NP underestimating the target angles. In SP, there are no differences between DL and NDL (p<0.005). On the contrary, in NP, at rest, the DL showed a significantly higher proprioceptive acuity, both in the 20º (p=0.046) as in the 45º range (p=0.036), although it was lower after the fatigue protocol at 45º range (p=0.050). In the NP, there were no gender differences in knee JPS. However, in the SP, after fatigue, JPS of the female players was significantly lower than male players, both in the 20º repositioning (p=0.041) as in the 45º range (p=0.046) of the DL. JPS of the SP didn’t vary throughout the season (p>0.005). In the knee extension test, a significantly lower proprioceptive acuity was observed in the 45º range, only in the NDL (p=0.012). In the knee flexion test, proprioceptive acuity was significantly lower at 45º than at 100º, both in the DL (p=0.004) as in the NDL (p=0.001). Conclusions: Fatigue doesn’t have acute effects on knee JPS in SP but decreases JPS in NP. Proprioceptive acuity is higher in SP than in NP. SP and NP fail the target ranges by over and underestimation, respectively. In SP, dominance doesn’t influence knee proprioceptive acuity, but in NP, the DL shows a higher acuity at rest, but lower in a fatigue state. At rest, there are no differences in knee JPS related to gender, although when in a fatigue state, the DL of the female players exhibits a lower acuity when compared to the male players. Chronic muscle overload doesn’t cause a variation of the knee JPS in SP throughout one season. Proprioceptive acuity is lower in the intermediate ranges of the knee range of motion.

Osteoarthritis is a degenerative disease of joints, which can be solved with implantation of total joints prosthesis. A high-quality proprioception of knee joint protects the joint against possible bending injury, it is also participating in stabilizing the knee in static position and it is important in the process of coordination of the motion system and precise flexibility of the knee joint. In this thesis are summed up the knowledge of osteoarthritis, total joints prosthesis and proprioception, all is taken in context of connection. The research includes comparison of proprioception of knee joint with arthrosis and total joints prosthesis. Also, the research compared mentioned knee joints with the healthy verification group. All monitored individuals absolved a medical examination of the quality of proprioception in the form of move sensitivity in position of 30ř, 50ř and 80ř. Amongst the knees with arthrosis and knees with total joints prosthesis there were not found a differences with static importance in each of the angle test. In the total comparison there was significantly better proprioception of the knees with the total joints prosthesis. The knee joints of the verification group unlike the joints with arthrosis and total prosthesis showed significantly better flexibility in position of...

Purpose The main purpose of this study was to determine the effectiveness of proprioceptive training in the ACL reconstructed limb. The second purpose of this study was to determine the relative contribution of isokinetic strength and peak hamstring torque time to functional ability. Methods Ten subjects with unilateral ACL reconstructed limbs were randomly assigned to two experimental groups. Group One (Strength Training Group) consisted of five subjects who were placed on a 12 week general lower body strength training program. Group Two (Proprioceptive Group) consisted of five subjects who were placed on a 12 week proprioceptive training program for the lower extremities. Peak hamstring torque time (PTT) was measured using the protocol described by Small et al.¹. Average concentric and eccentric torques of the quadriceps and hamstring muscles were measured using the KIN-COM isokinetic dynamometer. Functional ability was determined by the one-legged single hop for distance (SLHD) and the one-legged timed hop. Subjective scores were obtained from the Lysholm and Gillquist Knee Scoring Scale and the Tegner and Lysholm Activity Scale. Results Both training protocols were found to influence peak hamstring torque time of the ACL reconstructed limb. No significant differences were found between or within the two experimental groups. However, a group by test occasion interaction effect on peak hamstring torque time was found. A curvilinear relationship between PTT and test occasion was evident for both experimental groups. The strength training group demonstrated a slowing of PTT at 6 weeks, while the proprioceptive training group demonstrated an improvement in PTT at 6 weeks. At the end of the 12 weeks, both experimental groups regressed toward their baseline PTT values, such as the strength training group demonstrated an improvement in PTT while the proprioceptive training group demonstrated a slowing of PTT in the latter six weeks. There was a significant group by test occasion interaction effect on isokinetic strength measures. The proprioceptive group demonstrated greater isokinetic strength gains than the strength training group after 12 weeks of training. Both experimental groups demonstrated similar significant gains in functional ability. Both groups also demonstrated similar significant gains in the subjective assessment (Lysholm and Gillquist Knee Scoring Scale) and the subjective analysis of physical function (Tegner and Lysholm Activity Scale) after 12 weeks of training. Regressional analyses indicated isokinetic strength of the quadriceps and the hamstring muscles to have significant effects on functional ability (SLHD). Average concentric hamstring torque was found to have the most significant effect on functional ability. Conclusion Both strength training and proprioceptive training have an influence on peak torque time. It is proposed that the two types of training influence PTT through different neuromuscular mechanisms. Strength training is proposed to positively influence PTT by increasing fast twitch/slow twitch (FT/ST) muscle area ratio and to negatively influence PTT by decreasing muscle spindle sensitivity. Proprioceptive training is proposed to positively influence PTT by improving coordination and neural activation of the appropriate muscles. Coordination relies on proprioception and kinesthesia. However, the effectiveness of proprioceptive training is dependent on appropriate progression and repetition. Early integration of speed, force, and complexity of movement into proprioceptive training may decrease the effectiveness of training. Thus, the integration of these components should only occur if precision of performing motor tasks is not compromised. Both strength training and proprioceptive training may have beneficial effects on subjective scores and functional ability. Greater isokinetic strength gains can be observed with proprioceptive training than with strength training as training occurs over time. These greater isokinetic strength gains are proposed to be secondary to improved muscle coordination and neural activation rather than actual muscular hypertrophy. The strength of the lower extremities contribute significantly to functional ability. The strength of the hamstring muscle appear to play a greater role in functional ability than the quadriceps. However, due to the small sample size used in this study, the ability to generalize these results may be limited.

Research design： double-blinded randomized control trial, prospective study Background： Proprioceptive neuromuscular facilitation（PNF） stretching technique is a therapeutic technique applying the PNF concept and skills to the related muscles either to increase neuro-inhibition mechanism for releasing muscle spasm and elongating muscle length, or to increase neuro-excitation mechanism for enhancing muscle strength. Improvement in range of motion through PNF stretching technique has been documented superior to other techniques in previous literature, but those studies have only been done in healthy adults. Less is known in the effect of PNF stretching on improvement in joint restriction. Range of motion limitation usually disturbed the patients with total knee arthroplasty. PNF stretching techniques are commonly used in the treatment for patients with total knee arthroplasty to increase range of motion effectively and reduce knee pain during exercises. However, there is no evidence-based research in such a treatment strategy. This research, therefore, explored application of PNF stretch in changes of knee flexion, pain, muscle strength, and function of the lower extremity following total knee arthroplasty. Purposes： To investigate immediate and short-term effects on angle of knee flexion, intensity of pain, strength of the knee extensor, and function of the lower extremity by using PNF stretching technique in patients with total knee arthroplasty as compared to those using passive stretching technique. Method： Sixty-four patients who received total knee arthroplasty in National Taiwan University Hospital were recruited in this study. They were randomly allocated into either experimental or control groups with 32 participants in each. Conventional physical therapy programs were given to all participants. Besides, the experimental group assumed 3-session PNF stretching technique from the third post-operative day to the day of discharge while the control group receiving same-time passive stretching technique, instead. The outcome measures were taken before and after the first session treatment on the same day, on the day of discharge, and one month after the operation. The variables measured included knee flexion angle measured, maximum voluntary isometric strength of the knee extensor, pain score, timed up and go test, and Knee Injury and Osteoarthritis Outcome Score (KOOS). Results： The participants who received PNF stretching technique significantly increased knee flexion angle, enhanced muscle strength of the knee extensor, relieved pain at knee joint, and improved function of the lower extremities as compared to the controls, either immediately after PNF stretching, or on the day of being discharged from the hospital, or at one-month follow-up. Conclusions： Immediate increase in knee flexion angle and decrease in pain during motion were noted for patients receiving unilateral TKA following one-session application of PNF stretch technique. After receiving three-session treatment during hospitalization, the knee flexion angle in patients receiving PNF stretch technique was significantly greater than those receiving passive stretching technique. The fact that PNF stretching technique achieved their goals for discharge earlier in the experimental group might save medical cost and manpower. This effect continuing to improve until one-month follow-up resulted in reaching the condition which was only present one year after operation in previous literature. This is the first study in the world to apply the PNF stretching technique in patients with total knee arthroplasty. The randomized-control-trial nature of this study provides a strong evidence in clinical application of PNF technique.

The purpose of the study was to determine the effect of muscle fatigue on knee joint proprioception with specific fatigue protocol and functional weight-bearing position. Twenty-one healthy subjects were participated in this study. Electric goniometer and Kistler 9290 force plate with Quattro Jump program were used to measure knee joint flexion angles and fatigue index. 15 degrees of knee flexion was the starting position, and the target angles were set at 30, 45, and 60 degrees. The target angles were measured pre- and after fatigue exercise. One-way ANOVA and Turkey HSD post hoc were used to analyze mean differences of AAE among total knee joint and three target angles between each testing time in this study. AAE average graphs were used to describe the recovery status of knee joint proprioceptiion after muscle fatigue in this study. The findings demonstrated: 1. Total knee joint proprioception of pre- and after continuous jumps showed significant difference in functional weight-bearing position (p<.05). 2. All of the target angles showed significant differences of pre- and after continuous jumps (p<.05), but there were three testing times in the mid target angle (45 degrees) showed significant differences when compared with pre-fatigue AAE. 3. Muscle fatigue induced by continuous jumps influenced knee joint proprioception, and the worst of the knee joint proprioception happened at 5 minutes after continuous jumps. 4. The function of knee joint proprioception should rest at least 50 minutes in order to recovery from muscle fatigue induced by continuous jumps. Based on our findings, we suggested that sports activities which similar to continuous jumps, such as volleyball and basketball, should add muscle strength training programs to knee joint, and to ensure proper rest when encounter muscle fatigue, in order to prevent sports injury. Key Words: Continuous Jump, knee joint, muscle fatigue, proprioception, recovery time.

Purpose：To assess the effect of lower extremities exercise on knee proprioception, dynamic standing balance, functional performances in patients with osteoarthritic （OA）knees. Method：31 patients with OA knees were randomized into experimental（n=20） or control groups（n=11）.The patients in experimental group received lower extremities exercise consisted of three exercise sessions each week for 6 weeks. We compared knee proprioception, dynamic standing balance, and functional performances before and after an exercise regime in patients of experimental group. The patients of control group also received the same assessments before and after 6 weeks. Results: Knee proprioception improved after training in experimental group ( p=0.001) but not in control group ( P=0.22). In dynamic standing balance, medial and lateral weight shifting abilities did not reach the significant level in three testing levels in both groups. Forward and backward weight shifting abilities increased ( p=0.02) in experimental group after training. The movement time of the directions in forward（p=0.007）, left —forward （p=0.03）and right —forward（p=0.04）decreased in experimental group after training. The total movement time of 8 directions also decreased in experimental group after training（p=0.005）. Experimental group after training had significant improvement in all functional performances（p=0.005）. Conclusion:The 6-week lower extremity exercise program can improve the knee proprioception, dynamic standing balance, and functional performances in OA patients.
