Abstract
- BACKGROUND: In certain diseases, functional constraints establish a greater relationship with muscle power than muscle strength. However, in hereditary peripheral polyneuropathies, no such relationship was found in the literature. OBJECTIVE: In children with Charcot-Marie-Tooth (CMT), to identify the impact of muscle strength and range of movement on the static/dynamic balance and standing long jump based on quantitative and functional variables. METHOD: The study analyzed 19 participants aged between 6 and 16 years, of both genders and with clinical diagnoses of CMT of different subtypes. Anthropometric data, muscle strength of the lower limbs (hand-held dynamometer), ankle and knee range of movement, balance (Pediatric Balance Scale) and standing long jump distance were obtained by standardized procedures. For the statistical analysis, Pearson and Spearman correlation coefficients were used. RESULTS: There was a strong positive correlation between balance and the muscle strength of the right plantar flexors (r=0.61) and dorsiflexors (r=0.59) and a moderate correlation between balance and the muscle strength of inversion (r=0.41) and eversion of the right foot (r=0.44). For the long jump and range of movement, there was a weak positive correlation with right and left plantar flexion (r=0.20 and r=0.12, respectively) and left popliteal angle (r=0.25), and a poor negative correlation with left dorsiflexion (r=-0.15). CONCLUSIONS: The data on the patients analyzed suggests that the maintenance of distal muscle strength favors performance during balance tasks, while limitations in the range of movement of the legs seem not to be enough to influence the performance of the horizontal long jump. CONTEXTUALIZAÇÃO: Em algumas doenças, limitações funcionais têm maior relação com a potência do que com a força muscular, porém, nas polineuropatias periféricas hereditárias, tal relação não foi relatada na literatura. OBJETIVO: Identificar, a partir da análise de variáveis quantitativas e funcionais, o impacto da força dos músculos dos membros inferiores e das amplitudes de movimento (ADM) sobre o equilíbrio estático/dinâmico e o salto horizontal de crianças com doença de Charcot-Marie-Tooth (CMT). MÉTODO: Foram incluídos 19 participantes de seis a 16 anos, de ambos os sexos, com diagnóstico clínico de CMT de subtipos variados. Foram obtidos, de forma padronizada, dados antropométricos, força muscular dos membros inferiores (Hand-Held Dynamometer), ADM de tornozelos e joelhos, equilíbrio (Escala de Equilíbrio Pediátrica) e distância de salto horizontal (Long Jump). Para a análise estatística, utilizaram-se os Coeficientes de Correlação de Pearson e Spearman. RESULTADOS: Houve forte correlação positiva entre equilíbrio e força muscular de flexores plantares direito (r=0,61) e dorsiflexores (r=0,59) e correlação moderada com inversores dos pés (r=0,41) e eversores do pé direito (r=0,44). Considerando o Long Jump e as ADM, houve fraca correlação positiva para ADM de flexão plantar direita (r=0,20), esquerda (r=0,12) e ângulo poplíteo esquerdo (r=0,25) e fraca correlação negativa para dorsiflexão esquerda (r=-0,15). CONCLUSÕES: Os dados dos pacientes analisados sugerem que a manutenção de força muscular distal favorece o desempenho em tarefas de equilíbrio. E as restrições nas ADM passivas de membros inferiores parecem não ter sido suficientes para influenciar a potência muscular no salto horizontal.
