Objective: During the transitional phase (ambulatory to non-ambulatory), synergies characterize the evolution of Duchenne muscular dystrophy (DMD). This study was performed to describe and quantify compensatory movements while sitting down on/rising from the floor and climbing up/down steps. Method: Eighty videos (5 children × 4 assessments × 4 tasks) were recorded quarterly in the year prior to gait loss. Compensatory movements from the videos were registered based on the Functional Evaluation Scale for DMD. Results: The most frequently observed compensatory movements were upper limb support on lower limbs/floor/handrail during all the tasks and lumbar hyperlordosis, trunk support on handrail, equinus foot, increased base of support, non-alternated descent, and pauses while climbing up/down steps. Conclusion: Climbing up/down steps showed a higher number of compensatory movements than sitting down on/rising from the floor, which seemed to be lost before climbing up/down steps in ambulatory children with DMD.Keywords: Duchenne muscular dystrophy, evaluation, scales. RESUMOObjetivo: Durante a fase de transição (deambulador -não-deambulador), sinergias musculares caracterizam a evolução da distrofia muscular de Duchenne (DMD). Este estudo visou descrever e quantificar os movimentos compensatórios durante o sentar/levantar do solo, subir/descer degraus. Oitenta vídeos (5 crianças × 4 avaliações × 4 tarefas) foram gravados trimestralmente durante o ano que antecedeu a perda da marcha. Método: Os movimentos compensatórios dos vídeos foram registrados utilizando a Escala de Avaliação Funcional para DMD. Resultados: Os movimentos compensatórios mais frequentemente observados foram apoio de membros superiores nos membros inferiores/solo/corrimão durante todas as tarefas funcionais e hiperlordose lombar, apoio de tronco no corrimão, pés equinos, aumento da base de suporte, descida não alternada e pausas ao subir/descer degraus. Subir/descer degraus apresentou um número maior de movimentos compensatórios do que sentar/levantar do solo. Conclusão: Sentar/levantar do solo foram habilidades perdidas antes de subir/descer degraus em crianças com DMD.Palavras-chave: distrofia muscular de Duchenne, avaliação, escalas.

This pilot version of FES-DMD-GD showed reliability and correlated to age and timed motor performance.

Objectives: To estimate the impact of a sensory-motor-cognitive task on postural balance, in Parkinson disease patients (Hoehn and Yahr 2-3) and to investigate possible relationships between posturography and functional balance clinical scales. Method: Parkinson disease patients (n = 40) and healthy controls (n = 27) were evaluated with fluency tests, Berg Balance scale, Mini Best test and static posturography on the conditions eyes open, eyes closed and dual-task (simultaneous balance and fluency tasks). Results: Posturographic data showed that Parkinson disease patients performed worse than controls in all evaluations. In general, balance on dual-task was significantly poorer than balance with eyes closed. Posturographic data were weakly correlated to clinical balance scales. Conclusion: In clinical practice, Parkinson disease patients are commonly assessed with eyes closed, to sensitize balance. Our study showed that adding a cognitive task is even more effective. Static posturographic data should be carefully overgeneralized to infer functional balance impairments.

Objective:The relationship between functional dependence and quality of life (QOL) in Duchenne muscular dystrophy (DMD) patients and burden and QOL in caregivers is not clear. This study investigated possible relationships between functional dependence/QOL of DMD patients and QOL/burden of caregivers. Method: This study included 35 boys (6-17 years) and respective caregivers (above 21 years). Caregivers answered to World Health Organization Quality of Life and Zarit Burden Interview questionnaires. Patients were assessed with the Motor Function Measure and the Autoquestionnaire Qualité de vie Enfant Imagé. Spearman correlations and linear regressions were run to investigate relationships between the variables. Results: The occurrence of lower QOL and higher burden among the caregivers of patients with Duchenne muscular dystrophy was evidenced. The functional dependence of patients was not considered a determinant factor. Higher caregivers' burden was related to lower caregivers' QOL and to higher patients' ages.Keywords: Duchenne muscular dystrophy, behavior, quality of life, motor activity. RESUMOObjetivo: A relação entre qualidade de vida e função motora de pacientes com distrofia muscular de Duchenne (DMD) e sobrecarga e qualidade de vida (QV) dos cuidadores não está clara na literatura. Esse estudo investigou possíveis relações entre dependência funcional/ QV de pacientes e sobrecarga/QV dos cuidadores em 35 meninos (6-17 anos) com DMD e respectivos cuidadores (acima de 21 anos). Método: Cada cuidador respondeu ao questionário de QV da Organização Mundial de Saúde e de sobrecarga de Zarit e o paciente foi avaliado com a medida de função motora e o Autoquestionnaire Qualité de vie Enfant Imagé. Correlações de Spearman e regressões lineares investigaram possíveis relações entre as variáveis. Resultados: A ocorrência de menor QV e maior sobrecarga entre cuidadores foi evidenciada, enquanto a dependência funcional dos pacientes não foi considerada fator

Rising from the floor, climbing up, and climbing down steps have some components in common, such as the demand for muscle strength and the recruitment of compensatory muscle synergies, as DMD progresses. To sit down on the floor, some children let themselves fall, resulting in a faster performance, but more compensatory movements.
