Swing phase EMG RMS for subjects with spinal cord injury walking with and without manual assistance and control subjects at six different speeds. Averaged normalized muscle activation amplitudes 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) for the specified number of subjects with spinal cord injury and 6 control subjects. Bars indicate mean ± standard error. There were no significant differences in muscle activation amplitudes when walking with or without manual assistance (ANOVA, p > 0.05).
