Spinal motor evoked responses (sMERs) results. A The responses recorded at Pre and Post-intervention of Stim 2 in the TA and MG muscles of the paretic leg at stimulation intensities at L1 ranging from 50 to 180 mA (5 mA increments). Notably, both muscles responded at lower stimulation intensity (i.e., reduced RMT) at Post compared to Pre-intervention indicating improved spinal excitability. B, C Individual (line graph; identified by ID within groups) Pre–Post RMT changes for B TA muscle and C MG muscle. RMT resting motor threshold, TA tibialis anterior, MG medial gastrocnemius
