EMG profiles for subjects with spinal cord injury walking with (MA) and without (WO) manual assistance and control (C) subjects at 0.18 m/s. Averaged EMG profiles for tibialis anterior (TA), soleus (SO), medial gastrocnemius (MG), lateral gastrocnemius (LG), vastus medialis (VM), vastus lateralis (VL), rectus femoris (RF), and medial hamstring (MH) and averaged kinematic profiles for the ankle, hip and knee. Averages are taken from six subjects with spinal cord injury and six neurologically intact controls. Data from each subject were averaged over several step cycles within a trial, then over two trials of the same condition and speed, and finally averaged across subjects for the same condition and speed. Stride cycles were normalized from heel strike (0%) to heel strike of the same foot (100%). Vertical lines indicate the beginning of swing phase. The average coefficient of variation across subjects over the stride cycle is reported to the right of each plot.
