Figure 5. Comparison of the means of the smoothed rectified EMG signals of the amputee athlete: vastus medialis (VM), vastus lateralis (VL), rectus femoris (RF), and long head of biceps femoris (BF) at concentric (CON), eccentric (ECC), and both CON and ECC phases (TOTAL). The circles superimposed on the bar graph indicate the value of the non-disabled athlete in one typical turn cycle shown in Figure 4.
