Holanda – a fisioterapia pode retardar a deterioração funcional causada pelo desuso em meninos com distrofia muscular de Duchenne (DMD). O “Não uso é desuso” é o primeiro estudo exploratório estudo controlado, randomizado em meninos com DMD para analisar se o treinamento de bicicleta assistida é viável, seguro e benéfico. Trinta meninos (idade média de 10,5 ± 2,6 anos, 18 ambulantes e 12 cadeirantes foram incluidos para a intervenção (n = 17) ou controle (n = 13). O grupo tratado recebeu treinamento assistido com bicicleta para as pernas e braços durante 24 semanas. O grupo controle recebeu o mesmo treinamento, após um período de espera de 24 semanas. Os resultados primários do estudo foram a Medida da Função Motora (MFM) e do Teste de Ciclismo 6 minutos Assistido (A6MCT). Após 24 semanas os resultados obtidos com os pacientes treinados com bicicleta foram superiores aos controles com relação a AFM, sem altreração significativa em relação a A6MCT. Não foram observados efeitos adversos graves. Conclusões. o treinamento de bicicleta assistida das pernas e braços é viável e seguro para as crianças ambulantes e cadeirantes e pode diminuir a deterioração devido ao desuso.

Background. Physical training might delay the functional deterioration caused by disuse in boys with Duchenne muscular dystrophy (DMD). The “No Use Is Disuse” study is the first explorative, randomized controlled trial in boys with DMD to examine whether assisted bicycle training is feasible, safe, and beneficial. Methods. Ambulatory and recently wheelchair-dependent boys with DMD were allocated to the intervention or control group. The intervention group received assisted bicycle training of the legs and arms during 24 weeks. The control group received the same training after a waiting period of 24 weeks. The primary study outcomes were the Motor Function Measure (MFM) and the Assisted 6-Minute Cycling Test (A6MCT). Group differences were examined by an analysis of covariance. Results. Thirty boys (mean age 10.5 ± 2.6 years, 18 ambulant and 12 wheelchair-dependent) were allocated to the intervention (n = 17) or the control (n = 13) group. All boys in the intervention group (except one) completed the training. After 24 weeks, the total MFM score remained stable in the intervention group, whereas it had significantly decreased in the control group (Δ = 4.9, 95% confidence interval = 2.2-7.6). No significant group differences were found for the A6MCT. No serious adverse events were observed.Conclusions. Our results suggest that assisted bicycle training of the legs and arms is feasible and safe for both ambulant and wheelchair-dependent children and may decline the deterioration due to disuse. Progressive deterioration, however, may compromise the design of trials for DMD.
