Figure 4

Patterns of sagittal angular displacement (left panels) and power (right panels) of hip and ankle joints during natural walking for the subgroup of surgically operated CMT1A children: comparison between inter-subject average profiles at baseline (solid line) and follow-up (dotted line) evaluations. Letters ‘A’, ‘H’ and ‘K’ indicate the main changes (see text). The bottom panels show, for the same subgroup of patients, the patterns of ankle flexion-extension angle during heel-walking (left panel) and toe-walking (right panel). Arrows show the shift of ankle angular pattern between baseline and follow-up evaluations. Data of the healthy group are reported as control reference (grey area, mean ±1SD).
