RESUMO O estudo investigou se crianças com mielomeningocele melhorariam sua habilidade motora/funcional após dez sessões de fisioterapia e comparou o quadro motor de um grupo submetido à fisioterapia convencional (FC) com outro tratado com fisioterapia com estimulação reflexa (RF). Doze crianças foram alocadas em FC (n=6, 18,3 meses de idade) ou FR (n=6, 18,2 meses de idade). FR envolveu facilitação neuromuscular proprioceptiva. As crianças foram avaliadas com a Medida de Função Motora Grossa (GMFM) e o Inventário de Avaliação Pediátrica de Incapacidade (PEDI) antes e depois do tratamento. Testes de Mann-Whitney compararam a melhora na GMFM e PEDI (FC versus FR) e testes de Wilcoxon compararam FC e FR (antes versus depois). Possíveis correlações entre GMFM e PEDI foram testadas por coeficientes de Spearman. Ambos os grupos melhoraram na GMFM e PEDI (domínios autocuidado e mobilidade). Não houve diferença entre os grupos antes e após a intervenção. FC e FR apresentaram efeitos semelhantes depois de dez semanas de tratamento.

ABSTRACT We aimed to investigate whether infants with myelomeningocele would improve their motor ability and functional independence after ten sessions of physical therapy and compare the outcomes of conventional physical therapy (CPT) to a physical therapy program based on reflex stimulation (RPT). Twelve children were allocated to CPT (n = 6, age 18.3 months) or RPT (n = 6, age 18.2 months). The RPT involved proprioceptive neuromuscular facilitation. Children were assessed with the Gross Motor Function Measure and the Pediatric Evaluation of Disability Inventory before and after treatment. Mann-Whitney tests compared the improvement on the two scales of CPT versus RPT and the Wilcoxon test compared CPT to RPT (before vs. after treatment). Possible correlations between the two scales were tested with Spearman correlation coefficients. Both groups showed improvement on self-care and mobility domains of both scales. There were no differences between the groups, before, or after intervention. The CPT and RPT showed similar results after ten weeks of treatment.

ABSTRACT Objective: To determine the responsiveness of the domain climbing up and going down stairs of the Functional Evaluation Scale for Duchenne Muscular Dystrophy (FES-DMD-D3) in a one-year follow-up study. Method: The study included 26 patients with DMD. Effect Size (ES) and Standardized Response Mean (SRM) described the scale’s responsiveness. Results: For climbing up stairs, ES showed that responsiveness was low in the three-month assessments (0.26; 0.35; 0.13; 0.17), low to moderate in the six-month assessments (0.58; 0.48; 0.33), moderate in the nine-month assessments (0.70; 0.68), and high in the 12-month assessment (0.88). SRM showed that responsiveness was low in the three-month assessments (0.29; 0.38; 0.18; and 0.19), low to moderate in the six-month assessments (0.59; 0.51; 0.36), moderate in the nine-month assessments (0.74 and 0.70), and high in the 12-month assessment (0.89). For going down stairs, ES showed that responsiveness was low in the three- and six-month assessments (0.16; 0.25; 0.09; 0.08 and 0.48; 0.35; 0.18, respectively), low to moderate in the nine-month assessments (0.59; 0.44), and moderate in the 12-month assessment (0.71). SRM showed that responsiveness was low in the three- and six-month assessments (0.25; 0.35; 0.12; 0.09 and 0.47; 0.38; 0.21, respectively), low to moderate in the nine-month assessment (0.62; 0.49), and moderate in the 12-month assessment (0.74). Conclusion: Climbing up stairs should be assessed at intervals of nine months or longer, when responsiveness is moderate to high. Going down stairs should be assessed annually because moderate responsiveness was observed in this period.

RESUMO Mensurar força muscular e função motora é parte da avaliação em distrofia muscular de Duchenne (DMD). A relação entre essas variáveis é controversa. Objetivo Investigar a relação entre força muscular, função motora e idade. Método Força muscular foi medida pela Medical Research Council (MRC), e função motora pela escala Medida da Função Motora (MFM), em 40 pacientes cadeirantes. Teste de Spearman investigou as relações entre força muscular, função motora e idade. Resultados O escore total da escala MRC e da MFM foram fortemente relacionados entre si (r = 0,94; p < 0,001), mas não com a idade (r = -0,19; r = -0,31, respectivamente; p > 0,05). Foram encontradas correlações fortes e moderadas entre os escores parciais de força muscular e função motora. As relações mais fortes ocorreram entre os escores totais, Dimensão 2 (controle axial/proximal) e 3 (controle distal) da escala MFM. Conclusão Força muscular e função motora estão fortemente correlacionadas e parecem diminuir proporcionalmente na DMD.

ABSTRACT Measuring muscle strength and motor function is part of Duchenne muscular dystrophy (DMD) assessment. However, the relationship between these variables is controversial. Objective To investigate the relationship between muscle strength and motor function and between these variables and age. Method Muscle strength was measured by Medical Research Council (MRC) scale and motor function, by Motor Function Measure (MFM), in 40 non-ambulatory patients. Spearman tests investigated the relationships between muscle strength, motor function and age. Results Total MRC and MFM scores were strongly related to each other (r = 0.94; p < 0.001), but not to age (r = -0.19, r = -0.31, respectively; p > 0.05). Strong and moderate relationships between partial muscle strength and motor function scores were found. Higher correlation coefficients were found between total scores and Dimensions 2 (axial/ proximal control) and 3 (distal control) of MFM. Conclusion Muscle strength and motor function are strongly correlated and seem to decrease proportionally in DMD.

CONTEXTUALIZAÇÃO: Conhecer as potencialidades e limitações das informações geradas por diferentes instrumentos de avaliação favorece o desenvolvimento mais preciso do diagnóstico funcional e da tomada de decisão terapêutica. OBJETIVO : Investigar a relação entre o número de movimentos compensatórios ao subir e descer escadas, idade, classificação funcional e tempo de realização de atividade (TA) em meninos com Distrofia Muscular de Duchenne (DMD). MÉTODO : Foi utilizado banco de filmes de 30 meninos com DMD realizando atividades funcionais. Os movimentos compensatórios foram avaliados pela Escala de Avaliação Funcional para Distrofia Muscular de Duchenne (FES-DMD), domínio subir e descer escada; a idade, mensurada em anos; a classificação funcional foi pesquisada pela Escala de Vignos (EV), e o TA foi cronometrado. Foi utilizado o teste de correlação de Spearman. RESULTADOS : Existe moderada relação entre a FES-DMD-subir escada e a idade (r=0,53, p=0,004) e forte relação com a EV (r=0,72, p=0,001) e TA dessa tarefa (r=0,83, p<0,001). Houve fraca relação entre a FES-DMD-descer escada e a idade (r=0,40, p=0,032), EV (r=0,65, p=0,002) e o TA dessa tarefa (r=0,40, p=0,034). CONCLUSÃO : Esses achados indicam que a avaliação da tarefa de subir escada pode trazer informações mais relevantes sobre a evolução da doença, embora a atividade de descer escada deva ser pesquisada visando à orientação e prevenção de acidentes. A utilização conjunta de dados provenientes da FES-DMD, da idade e do TA pode se complementar para formulação do diagnóstico funcional. Estudos longitudinais e com outras faixas etárias mais amplas podem complementar tal informação.

BACKGROUND: Knowing the potential for and limitations of information generated using different evaluation instruments favors the development of more accurate functional diagnoses and therapeutic decision-making. OBJECTIVE: To investigate the relationship between the number of compensatory movements when climbing up and going down stairs, age, functional classification and time taken to perform a tested activity (TA) of going up and down stairs in boys with Duchenne muscular dystrophy (DMD). METHOD: A bank of movies featuring 30 boys with DMD performing functional activities was evaluated. Compensatory movements were assessed using the climbing up and going down stairs domain of the Functional Evaluation Scale for Duchenne Muscular Dystrophy (FES-DMD); age in years; functional classification using the Vignos Scale (VS), and TA using a timer. Statistical analyses were performed using the Spearman correlation test. RESULTS: There is a moderate relationship between the climbing up stairs domain of the FES-DMD and age (r=0.53, p=0.004) and strong relationships with VS (r=0.72, p=0.001) and TA for this task (r=0.83, p<0.001). There were weak relationships between the going down stairs domain of the FES-DMD-going down stairs with age (r=0.40, p=0.032), VS (r=0.65, p=0.002) and TA for this task (r=0.40, p=0.034). CONCLUSION: These findings indicate that the evaluation of compensatory movements used when climbing up stairs can provide more relevant information about the evolution of the disease, although the activity of going down stairs should be investigated, with the aim of enriching guidance and strengthening accident prevention. Data from the FES-DMD, age, VS and TA can be used in a complementary way to formulate functional diagnoses. Longitudinal studies and with broader age groups may supplement this information.
