Background Stroke is among the three leading causes of disability around the world, and it results in immediate difficulty in mobility and gait. There is a lack of instruments to evaluate what daily life is like for these individuals using their lower limbs in real-life environments (outside of the clinical environment). Objective To perform the translation and cultural adaptation to Brazilian Portuguese of the Lower-Extremity Motor Activity Log (LE-MAL) and test its measurement properties in chronic poststroke individuals. Methods The LE-MAL was translated into Brazilian Portuguese and adapted to the Brazilian culture. The comprehension and relevance of the final version were analyzed by a committee of specialists. The reliability, validity, and responsiveness of the LE-MAL/Brazil to detect changes after lower extremity constraint-induced movement therapy (LE-CIMT) and an intensive conventional therapy were tested. Results The LE-MAL/Brazil showed excellent inter- and intrarater reliability, with an intraclass correlation coefficient and Cronbach alpha > 0.70, as well as standard error of measurement and smallest detectable change 0.50.

Multiple sclerosis is a demyelinating disease of the central nervous system associated with varied levels of disability. The impact of early physiotherapeutic interventions in the disease progression is unknown. We used an experimental model of demyelination with the gliotoxic agent ethidium bromide and early aquatic exercises to evaluate the motor performance of the animals. We quantified the number of footsteps and errors during the beam walking test. The demyelinated animals walked fewer steps with a greater number of errors than the control group. The demyelinated animals that performed aquatic exercises presented a better motor performance than those that did not exercise. Therefore aquatic exercising was beneficial to the motor performance of rats in this experimental model of demyelination.A esclerose múltipla é uma doença desmielinizante do sistema nervoso central que se associa a graus variados de incapacidade. Não se sabe se a realização de intervenções fisioterapêuticas precoces têm impacto na evolução dessa doença. Utilizamos um modelo experimental de desmielinização com o gliotóxico brometo de etídio e a aplicação de exercícios aquáticos precoces para avaliar o desempenho motor dos animais. Foram quantificados o número de passos e os erros executados durante a travessia da barra elevada. Os animais desmielinizados apresentaram menor número de passos e maior quantidade de erros em comparação aos grupos-controle. Os animais desmielinizados que realizaram exercícios aquáticos apresentaram melhor desempenho motor que os animais desmielinizados que não foram submetidos à intervenção. Portanto, a realização de exercícios aquáticos mostrou-se benéfica no desempenho motor dos animais submetidos ao modelo experimental do brometo de etídio.
