Overview on percentage of MFM-20/32 total score, MiniBEST, PBS and HFMS; the percentage of distance predicted at the 6MWT; the percentage of predicted strength (N) of several muscles; the percentage of sedentary, light, moderate and vigorous activity and the number of counts per day as measured through accelerometry (mean±SD); and the correlation between the MFM-20/32 total score and percentage of sedentary activity. (A) Percentage of MFM-20/32 total score, MiniBEST, PBS and HFMS; and the percentage of distance predicted at the 6MWT. MFM-20/32 was performed by all patients participating in this study. The MiniBEST and PBS were performed by ambulant patients, while the HFMS was only performed by patients who were not able to perform either of the two balance tests (MiniBEST or PBS) due to physical limitations (n = 3). 6MWT included all ambulant patients of 5 years and older that were seen in the hospital (n = 8). (B) Percentage of predicted strength (N) of the neck extensor, biceps brachii, triceps brachii, quadriceps, foot dorsiflexor and foot flexor muscles and the pinch grip. n = the number of patients (each patient having two muscles examined, i.e. left and right side); (C) Percentage of sedentary, light, moderate and vigorous activity and the number of counts per day as measured through accelerometry. (D) Percentage sedentary activity as measured through accelerometry was negatively correlated to the MFM-20/32 total score (Pearson’s correlation, –0.682, p < 0.05). MFM-20/32 = motor function measurement 20/32; MiniBEST = Mini Balance Evaluation Systems Test; PBS = Pediatric Balance Scale; HFMS = Hammersmith Functional Motor Scale; 6MWT = 6-minute walk test. All values are mean±SD.
