Patterns of ankle flexion-extension angle during natural walking (left panel), heel-walking (center panel) and toe-walking (right panel) for each CMT1A subgroup: comparison between inter-subject average profiles at baseline (solid line) and follow-up (dotted line) evaluations. Data of the healthy group is reported as control reference (grey area, mean ±1SD). Arrows show the main changes between baseline and follow-up evaluations in heel- and toe-walking.
