2. Fig. 1
The EMG data for the hamstrings and quadriceps muscle groups and the area of overlap (shaded) across a gait cycle for a single subject. (A) The area of overlap when each muscle is unscaled and expressed in millivolts; (B) the same data scaled to the respective percentage of the maximal voluntary contraction value for each muscle; (C) the same data scaled to the percentage maximal voluntary contraction as in (B) and then weighted by the estimated degree of weakness. Rquad, right quadriceps; Rham, right hamstring.
