To determine physical function and activity level in children and adolescents with neuromuscular disorders.
Seventeen children and adolescents aged 10 to 18 years with neuromuscular disorders who were ambulatory participated. Physical function was measured using the Hammersmith Motor Ability Scale and the Six-Minute Walk Test. Physical activity (PA) level was measured using the SenseWear Armband activity monitor. Activities were recorded using a questionnaire. Results were compared with previous data published for peers who are healthy and public recommendations.
Hammersmith Motor Ability Scale scores were lower than normal values. Results of the Six-Minute Walk Test were considerably lower than results for peers who are healthy. Time in PA and the number of steps were considerably lower on holidays and slightly lower on weekdays compared with the values for peers who are healthy. No vigorous activity was registered.
The participants had lower physical function and PA levels than peers who are healthy. The small, heterogeneous sample makes generalizations challenging and multicenter studies are recommended.
