Figure 5.

Extracted averages and standard deviations, maximums, minimums, and values at 25% of the squat cycle and 75% of the squat cycle for each variable. These parameters were extracted from Figure 4 data and used to compare user behavior for the B and E modes. 5a shows the timing of each squat, 5b shows the knee flexion angle parameters, 5c shows B-normalized rectus femoris muscle activity, and 5d shows B-normalized bicep femoris muscle activity. The results of the Mann–Whitney U test are shown in the subfigures as p-values and with a * when p < .05 and a ** when p < .01.
