ABSTRACT
AIM: To investigate the validity and reproducibility of the Glittre Activities of Daily Living (Glittre-ADL) test for individuals with Parkinson's disease. SUBJECTS AND METHODS: Thirty individuals with Parkinson's disease and 19 healthy individuals (control group) were evaluated. Parkinson's disease group was evaluated by the Unified Parkinson's Disease Rating Scale (UPDRS) and underwent the Glittre-ADL test, six-minute walk test (6MWT) and ten-meter walk test (10mWT). Control group performed the Glittre-ADL test. For the intraobserver analysis, two Glittre-ADL tests were performed. For the interobserver analysis, the Glittre-ADL test was repeated on a different day by a second examiner. RESULTS: The Glittre-ADL test was significantly correlated with UPDRS Section II, Section III, and total score. The Glittre-ADL test was inversely correlated with the 6MWT and positively correlated with the 10mWT. The time required to perform the Glittre-ADL test was shorter on the retest in the intraobserver analysis and in the interobserver analysis. The mean difference between the first and second tests, the standard error of measurement and minimum detectable change in minutes were 0.40, 0.08 and 0.24, respectively, for intraobserver, and 0.40, 0.22 and 0.62, for interobserver. CONCLUSION: The Glittre-ADL test is valid and reproducible to evaluate functional capacity in individuals with Parkinson's disease.
TITLE: Validación y reproducibilidad de la prueba Glittre de actividades de la vida diaria en personas con enfermedad de Parkinson.Objetivo. Investigar la validez y la reproducibilidad de la prueba Glittre de actividades de la vida diaria (AVD-Glittre) para personas con enfermedad de Parkinson. Sujetos y métodos. Se evaluó a 30 pacientes con enfermedad de Parkinson y 19 sujetos sanos (grupo de control). El grupo con enfermedad de Parkinson fue evaluado con la Unified Parkinson's Disease Rating Scale (UPDRS) y sometido a la prueba AVD-Glittre, la prueba de marcha de seis minutos (6MWT) y la prueba de marcha de 10 metros (10mWT). El grupo de control realizó la prueba AVD-Glittre. Para el análisis intraobservador se realizaron dos pruebas AVD-Glittre, y para el análisis interobservador, la prueba se repitió otro día con un segundo examinador. Resultados. La prueba AVD-Glittre se correlacionó significativamente con la sección II, la sección III y la puntuación total de la UPDRS. Se correlacionó inversamente con la 6MWT y positivamente con la 10mWT. El tiempo requerido para realizar la prueba AVD-Glittre fue más corto en la nueva prueba en el análisis intraobservador y en el análisis interobservador. La diferencia de medias entre la primera y la segunda pruebas, el error estándar de medición y el cambio mínimo detectable en minutos fueron 0,40, 0,08 y 0,24, respectivamente, para el análisis intraobservador, y 0,40, 0,22 y 0,62, respectivamente, para el análisis interobservador. Conclusión. La prueba AVD-Glittre es válida y reproducible para evaluar la capacidad funcional en personas con enfermedad de Parkinson.

INTRODUCTION: Following poliomyelitis, patients may experience sleep disorders stemming from periodic limb movement, leading to fatigue and compromised muscle function the following day. AIM: To establish the presence or absence of muscle fatigue in these patients using electromyography and relating the data to polysomnographic findings. PATIENTS AND METHODS: An analytical cross-sectional study was carried out involving 19 individuals with motor sequelae in the lower limbs stemming from poliomyelitis. Quantitative tests for the assessment of neurophysiological aspects (knee-jerk/Achilles reflexes and peripheral muscle strength of rectus femoris) and a sleep study (standard, level I polysomnography) were administered. RESULTS: A statistically significant difference was detected (p < 0.01) in muscle strength, demonstrating muscle fatigue associated to sleep disorder. CONCLUSION: Individuals with sequelae from poliomyelitis exhibit sleep disorders that may lead to muscle fatigue. Periodic limb movement may contribute to this phenomenon.

OBJECTIVE: To quantify and compare parameters of muscle electrical activity and ground reaction force of lower limb during gait in post-stroke patients with left or right side functional involvement. METHOD: Fifteen post-stroke volunteers with left side functional involvement were age, gender and weight matched and compared to fifteen post-stroke volunteers with right side functional involvement. Comparison was executed by means of electromyography with four pairs of surface electrodes positioned on the affected side (spastic side), on the muscles rectus femoris, tibialis anterior, soleus, and medial portion of the hamstrings, and with a ground reaction force plate. RESULTS: There was no statistically significant difference on electromyographic activity of analyzed muscles (p = 0.6), nor on the analysis of ground reaction vertical forces, stride duration, weight bearing index, gait velocity, cadence and stride length (p = 0.53). CONCLUSION: According to the electromyographic parameters and to the ground reaction force during gait among the post-stroke volunteers with right or left side involvement; we could suggest that functional rehabilitation presented no differences for these individuals.

Proceed to a comparative analysis of the electromyographic (EMG) activity of the muscles rectus femoris, vastus medialis and vastus lateralis, and to assess muscle strength and fatigue after maximal isometric contraction during knee extension. Eighteen patients with post-polio syndrome, age and weight matched, were utilized in this study. The signal acquisition system utilized consisted of three pairs of surface electrodes positioned on the motor point of the analyzed muscles. It was possible to observe with the results of this study a decreased endurance on initial muscle contraction and during contraction after 15 minutes of the initial maximal voluntary contraction, along with a muscle fatigue that was assessed through linear regression executed with Pearson's test. There were significant differences among the comparative analysis of EMG activity of the muscles rectus femoris, vastus medialis and vastus lateralis after maximal isometric contraction during knee extension. Initial muscle contraction and contraction after a 15 minute-rest from initial contraction decreased considerably, indicating a decreased endurance on muscle contraction, concluding that a lower limb muscle fatigue was present on the analyzed PPS patients.

Ha uma crescente preocupacao com o estudo da articulacao do joelho durante atividade funcionais com a marcha humana, embora haja estudos detalhados extensos sobre essa tematica, nada ha na literatura sobre a analise eletromiografica da articulacao do joelho,associando-a a instabilidade femuro-pastelar. O presente estudo teve por objetivo apresrntar atividade eletromiografica dos musculos vasto medial obliquo e vasto lateral, durante a marcha realizada em aclive e declive. Os resultados, por meio da analise do coeficiente de variacao e correlacao cruzada no dominio temporal, indicaram a existencia de padroes semelhantes para as curvas eletromiograficas medias dos musculos supra citados dos voluntarios.Concluiu-se, portanto, que existe um padrao comum de atividade em voluntarios saudaveis para os musculos vasto medial obliquo e vasto lateral
