Figure 1.

Differences between control and femoroacetabular impingement syndrome (FAIS) groups for A, anteroposterior ground reaction force preoperatively and B, vertical ground reaction force 3 months postoperatively. Black bars with P values indicate regions of significant statistical parametric mapping analyses. Normalized mean (line) and SDs (shading) represent control (solid line indicates mean; diagonal shading indicates SD) and FAIS (dashed line indicates mean; vertical shading indicates SD) groups.
