Resumo: The aim of this study was to evaluate anaerobic muscle performance in children after long-term recovery from Guillain-Barré syndrome (GBS). Participants were recruited from all children and adolescents with GBS admitted to The Hospital for Sick Children, University of Toronto, Canada, between 1988 and 1995. We assessed 17 children (nine males, eight females; mean age at GBS diagnosis 7 years 11 months, SD 4 years 2 months; mean age at testing 14 years 1 month) more than two years after acute GBS. Participants completed the Wingate anaerobic test to evaluate mean and peak muscle power. For mean arm muscle power (mean 47.5% [SD 17.4%] of normal), only two participants were in the normal range. For mean leg muscle power (mean 83% [SD 28.3%] of normal), 15 participants were in the normal range. For arm peak power (mean 92.6% [SD 20.7%] of normal), 12 participants were in the normal range. For leg peak power (mean 116.3% of normal, SD 15.8%), all participants were in the normal range. Detailed manual muscle testing with the modified Medical Research Council scale was done on 34 muscle groups. Data were pooled to give a mean arm and leg muscle strength score (9.7, SD 0.30 and 9.4, SD 0.50 respectively). Pearson's correlations of muscle endurance with arm and leg strength were not significant. Children with GBS have excellent long-term recovery of peak muscle power. Muscle endurance, measured by mean muscle power, was normal in the legs but markedly low in the arms. Pediatric rehabilitation programs after GBS should specifically target endurance of arm muscles.
