Triceps surae cutaneous reflexes to non-noxious stimuli in people with and without chronic incomplete SCI. a and b: 20 peristimulus EMG sweeps to 5 × perceptual threshold (PerT) level of superficial peroneal nerve (SPn) stimulation are superimposed for a person without SCI (a) and a person with chronic SCI (b). A pink highlighted time window indicates the window for the medium latency reflex (MLR). c: Amplitudes of soleus MLRs (group mean ± SD) to stimulation of the SPn, sural nerve (SRn), and distal tibial nerve (DTn) at 5 × PerT in individuals with SCI (filled bars) and without injuries (open bars). The reflex amplitudes are expressed in %maximum M-wave (Mmax)124. d: Amplitudes of MG MLRs to stimulation of the SPn, SRn, and distal DTn stimulation at 5 × PerT. e: Amplitudes of LG MLRs to stimulation of the SPn, SRn, and distal DTn stimulation at 5 × PerT. Asterisks indicate significant differences between the groups (p < 0.05). Each x symbol represents an individual’s value. The number of participants in each dataset is denoted next to the figure legend.
