2. Fig. 1
Hip joint rotation (deg) in the transverse plane (N, normal walking; L, 10%PWB; M, 50%PWB; H, 90%PWB). (A) The involved side has internal rotation of approximately 2° to 6°, whereas (B) the noninvolved side has external rotation of approximately 2° to 6° during walking.

3. Fig. 2
Hip joint abduction and adduction (deg) in the M/L plane (N, normal walking; L, 10%PWB; M, 50%PWB; H, 90%PWB). (A) The involved side is maintained in slight adduction, and (B) the noninvolved side is maintained in slightly abducted position at foot strike in the M/L plane.

4. Fig. 3
Vertical GRF (BW) on both sides (N, normal walking; L, 10%PWB; M, 50%PWB; H, 90%PWB). (A) Vertical GRF on the involved side is not consistent with expected levels. (B) No increases in vertical GRF occur on the noninvolved side.
