Mean power frequency (MPF) of electromyographic (EMG) power spectrum during walking. The overall MPF (Hz) from left and right soleus (SOL), medial gastrocnemius (MG), peroneus longus (PL), and tibialis anterior (TA) muscles during walking on a motorized treadmill in able bodied subjects (A) or with the Lokomat6^®Pro in individuals with spinal cord injury (SCI; B). The MPF is shown for the steps without or during single pulse (SP) or pulse train (PT) transspinal stimulation at each bin of the step cycle. The step cycle was divided into 16 equal bins. Bin 1 corresponds to heel contact. Bins 8, 9, and 16 correspond approximately to stance-to-swing transition, swing phase initiation, and swing-to-stance transition, respectively.
