FIGURE 2.

Measured and predicted hip contact forces during activities for (A–G) HSR, (H–N) KWR, and (O–U) PFL. The ensemble average of all trials and standard deviations are shown (n shows the number of trials for each activity). Each row shows on activity, and each column shows the results for one subject. WN, WS, WF, SU, SD, CD, and CU stand for normal walking, slow walking, fast walking, stair ascent, stair descent, sitting down and standing up, respectively. BW and HCF stand for body weight and hip contact force.
