Participation in leisure activities from the perception of children with disabilities and their families in Brazil.

OBJECTIVE: To understand the perception of children with disabilities and their families regarding factors that interfere with participation in leisure activities in Brazil. METHODS: This qualitative study included 14 focus groups, involving a total of 80 participants (40 children with disabilities and 40 family members). Discus-sions were recorded and transcribed. Coding was based on the International Classification of Functioning Disability and Health, following linking rules. RESULTS: A total of 80 individuals participated in the study. For parents and children the most-cited barriers to participation in leisure activities were relat-ed to environmental factors. For children, the main barriers were the attitudes of their nuclear family, acquaintances, and friends. Access to products and technology for personal mobility were also important obstacles. For them, support from immediate family was both a facilitator and barrier. Other barriers identified by family members were open-space planning services and assets. As facilitators, the atti-tudes and support of people in positions of authority also were reported by this group. CONCLUSION: For parents and children, most disabling barriers were related to environmental factors, such as access to products and technology, support, and attitudes. Some differences in perception were observed between comments from children and parents; for example, regarding barriers due to immediate family. Parents showed greater awareness of barriers and facilitators to participation in leisure activities.

Post-stroke hemiparesis: Does chronicity, etiology, and lesion side are associated with gait pattern?

BACKGROUND: Studies that evaluate gait rehabilitation programs for individuals with stroke often consider time since stroke of more than six months. In addition, most of these studies do not use lesion etiology or affected cerebral hemisphere as study factors. However, it is unknown whether these factors are associated with post-stroke motor performance after the spontaneous recovery period. OBJECTIVE: To investigate whether time since stroke onset, etiology, and lesion side is associated with spatiotemporal and angular gait parameters of individuals with chronic stroke. METHODS: Fifty individuals with chronic hemiparesis (20 women) were evaluated. The sample was stratified according to time since stroke (between 6 and 12 months, between 13 and 36 months, and over 36 months), affected cerebral hemisphere (left or right) and lesion etiology (ischemic and hemorrhagic). The participants were evaluated during overground walking at self-selected gait speed, and spatiotemporal and angular gait parameters were calculated. Results Differences between gait speed, stride length, hip flexion, and knee flexion were observed in subgroups stratified based on lesion etiology. Survivors of a hemorrhagic stroke exhibited more severe gait impairment. Subgroups stratified based on time since stroke only showed intergroup differences for stride length, and subgroups stratified based on affected cerebral hemisphere displayed between-group differences for swing time symmetry ratio. CONCLUSION: In order to recruit a more homogeneous sample, more accurate results were obtained and an appropriate rehabilitation program was offered, researchers and clinicians should consider that gait pattern might be associated with time since stroke, affected cerebral hemisphere and lesion etiology.

Influence of treadmill gait training with additional load on motor function, postural instability and history of falls for individuals with Parkinson's disease: A randomized clinical trial.

BACKGROUND: Evaluate the effects of additional load (5% and 10% of body weight) with treadmill gait training on the motor aspects in Parkinson's disease (PD). METHODS: Randomized controlled single-blind trial with 30 individuals with PD. The volunteers were divided into three groups (treadmill with 0%, 5% or 10% load), where Unified Parkinson's Disease Rating Scale was applied. Treadmill gait training was conducted over 4 consecutive weeks, with three weekly sessions of 30 min each. RESULTS: There was a significant reduction in all groups in the time factor for motor function (F = 12.92; P = 0.001) and postural instability (F = 11.23; P = 0.002). No significant difference was observed in group × time interaction (F < 1.76; P > 0.19). CONCLUSION: The treadmill comprises an effective therapy for people with PD, for important motor aspects such as motor function and postural instability. Additional load had no influence on results.

Effects of treadmill inclination on hemiparetic gait: controlled and randomized clinical trial.

OBJECTIVE: The aim of this study was to analyze the effects of inclined treadmill training on the kinematic characteristics of gait in subjects with hemiparesis. DESIGN: A blind, randomized, controlled study was conducted with 28 subjects divided into two groups: the control group, submitted to partial body weight-support treadmill gait training with no inclination, and the experimental group, which underwent partial body weight-support treadmill training at 10% of inclination. All volunteers were assessed for functional independence, motor function, balance, and gait before and after the 12 training sessions. RESULTS: Both groups showed posttraining alterations in balance (P < 0.001), motor function (P < 0.001), and functional independence (P = 0.002). Intergroup differences in spatiotemporal differences were observed, where only the experimental group showed posttraining alterations in velocity (P = 0.02) and paretic step length (P = 0.03). Angular variables showed no significant differences in either group. CONCLUSIONS: In subjects with hemiparesis, the addition of inclination is a stimulus capable of enhancing the effects of partial body weight-support treadmill gait training.

Influence of treadmill training in dual-task gait in people with Parkinson's Disease: a case report / Influencia del entrenamiento en cinta rodante em la marcha de doble tarea en indivíduos con la enfermedad de Parkinson: um estúdio de caso / Influência do treino em esteira na marcha em dupla tarefa em indivíduos com Doença de Parkinson: estudo de caso

The loss in the automaticity of gait hinders the performance of concurrent activities - Dual Task (DT) - in individuals with Parkinson's disease (PD). One hypothesis for the negative interference of DT on gait is related to the limitation of attention resources in the brain for different activities. When the automation of a task occurs, the negative interference of DT on the gait can be minimized. Because the treadmill promotes automaticity of a better locomotion pattern, due to the repetition that promotes motor learning, the study sought to investigate whether treadmill training can improve the performance of gait on DT in people with PD. Three individuals were evaluated in the on-phase of the antiparkinsonian medication regarding the kinematics (Qualisys Motion Capture System) while in gait, simultaneously performing cognitive activities. Subsequently, the subjects performed a 20-minute workout on the treadmill and were reassessed during gait in cognitive activities. There were increases in the length of the cycle (p=0.01), the length of the step (p=0.01) and in total swing time (p=0.03), and a decrease in the total length of support (p=0.03). These results indicate that treadmill training can promote improvement in the performance of DT on gait in individuals with PD. Longitudinal studies with this focus of research are needed.

La pérdida en el automatismo de la marcha dificulta la realización de actividades simultáneas - Doble Tarea (DT) - en personas con enfermedad de Parkinson (EP). Una hipótesis para la interferencia negativa de la DT en la marcha está relacionada con la limitación de recursos cerebrales de atención para diferentes actividades. Cuando se produce la automatización de una de las tareas, la interferencia negativa de la DT sobre la marcha podrá ser minimizada. Como la cinta de correr promueve la automaticidad de un mejor patrón locomotor, debido a la repetición que favorece el aprendizaje motor, el estudio trató de investigar si el entrenamiento en cinta de correr puede mejorar el desempeño de marcha en DT en personas con EP. Tres individuos fueron evaluados en la fase on del medicamento antiparkinsoniano en cuanto a la cinemática (Qualisys Motion Capture System), mientras se realizaba la marcha simultáneamente a actividades cognitivas. Posteriormente, los individuos realizaron un entrenamiento de 20 minutos en la cinta y fueron evaluados de nuevo durante la marcha en actividades cognitivas. Hubo aumentos en longitud de la pasada (p=0,01), la longitud del paso (p=0,01) y en el tiempo total del abalanzar (p=0,03) y una disminución de en tiempo total de apoyo (p=0,03). Estos resultados indican que el entrenamiento en cinta puede promover la mejora en el rendimiento de marcha en DT en personas con EP, y que se necesitan estudios longitudinales con este enfoque de investigación.

A perda na automaticidade da marcha dificulta a realização de atividades concorrentes - Dupla Tarefa (DT) - em indivíduos com Doença de Parkinson (DP). Uma hipótese para a interferência negativa da DT sobre a marcha está relacionada à limitação de recursos cerebrais atentivos para as diferentes atividades. Caso ocorra a automatização de uma das tarefas, a interferência negativa da DT sobre a marcha poderá ser minimizada. Como a esteira promove automaticidade de um melhor padrão locomotor, devido à repetição que favorece a aprendizagem motora, o estudo buscou investigar se o treino em esteira pode melhorar o desempenho de marcha em DT em pessoas com DP. Três indivíduos foram avaliados na fase on do medicamento antiparkinsoniano quanto à cinemetria (Qualisys Motion Capture System), enquanto realizavam a marcha simultaneamente a atividades cognitivas. Posteriormente, os indivíduos realizaram um treino de 20 minutos na esteira e foram reavaliados durante a marcha em atividades cognitivas. Houve aumentos no comprimento da passada (p=0,01), no comprimento do passo (p=0,01) e no tempo total de apoio (p=0,03). Esses resultados indicam que o treino em esteira pode promover melhora no desempenho de marcha em DT em indivíduos com DP, sendo necessários estudos longitudinais com esse foco de investigação.

Effects of adding load to the gait of children with cerebral palsy: a three-case report / Efectos de la adición de carga sobre la marcha de niños con parálisis cerebral: relato de tres casos / Efeitos da adição de carga na marcha de crianças com paralisia cerebral: relato de três casos

Our purpose in this study was to analyze the immediate effects of locomotor gait training with different loads on a treadmill on the kinematic parameters of gait in children with Spastic Hemiparetic Cerebral Palsy (SHCP), as well as investigating which load prompted the most adequate motor responses to promote the propulsion of the Paretic Lower Limb (PLL). This case report included 3 children of both sexes, aged 8-12 years. The children walked on the treadmill with loads on their ankles that corresponded to 40, 50 and 60% of the weight of the Lower Limb (LL), on 3 different non-consecutive days. The kinematic parameters were assessed during the pre-training phase (PTPH) and immediately after training (PHI). The spatiotemporal variables did not change immediately after gait training with the aforementioned loads. On the other hand, we observed wider joint angles in the hip and knee during the swing phase immediately after training, especially with a load of 60% of the weight of the lower limb. These findings indicate that the 60% load is the most appropriate to prompt immediate changes in the joint kinematics of the PLL. These alterations can be important in improving propulsion during the swing phase of gait in children with SHCP...

El objetivo de este estudio fue analizar los efectos inmediatos del entrenamiento locomotor en la estera con diferentes cargas, sobre los parámetros cinemáticos de la marcha de niños con parálisis cerebral hemipléjica espástica (PCHE), e investigar cómo la carga promueve respuestas motoras más adecuadas para favorecer la propulsión del Miembro Inferior Parético (MIP). Participaron de este caso, 3 niños de ambos sexos, con edades de 8-12 años. Los niños realizaron entrenamiento en la estera rodante con carga en los tobillos equivalente a 40, 50 y 60% del peso de la miembro (MI), en 3 días distintos y no consecutivos. Los parámetros cinemáticos fueron evaluados en las fases de pre entrenamiento (FPT), e inmediatamente después del entrenamiento (FI). Las variables espacio-temporales no cambiaron inmediatamente después del ejercicio de marcha con carga. Sin embargo, fue observado aumento de los ángulos articulares de la cadera y la rodilla durante la fase de balanceo inmediatamente después del entrenamiento, especialmente con carga de 60% del peso de la extremidad inferior. Estos resultados indican que la carga de 60% es la más apropiada para solicitar cambios inmediatos en la cinemática articular del MIP. Tales cambios pueden ser importantes para fomentar la propulsión durante la fase de balanceo de la marcha de niños con PCHE...
