Figure 5
Effects of significant angular changes at individual joints on the leading toe-obstacle clearance in the frontal plane. (A) Postural and end-point position differences between the DMD group (black stick figure) and the Control group (grey stick figure) when crossing an obstacle of 20% leg length. For the DMD group, increased pelvic hiking (B) tended to increase the toe-obstacle clearance. With the stance-foot immobilized on the ground, the sub-figures were obtained by rotating the distal part of the pelvis-leg apparatus at one joint at a time while keeping the other joints immobilized according to the significant angular changes reported in Table 3.
