Table 4 The range of motion (mean±SD) of the investigated joints for patients with spinal muscular atrophy divided according to functional status. For walkers only, min–max values are given due to the low number. The difference between the first and second examinations was calculated using the Wilcoxon test; z and P values are shown.
