Figure 3. Flexion enhancement by stimulation of flexor nerves.

Figure 3

A, stimulation of PerL (25 shocks at 200 Hz, dotted lines) was triggered by Sart ENG activity. PerL stimulation increased amplitude but not burst duration of other flexor nerves. The activity in LGS during the stimulus delivery is stimulus artefact. Arrows indicate the increased amplitude of hip (Sart) and ankle (TA and EDL) flexor ENGs during stimulation. B, the effects of stimulation of the Psoas and Sart nerve (trains of 30 pulses, 200 Hz) at 5T delivered during flexion over 38 steps from a 70 s long bout of MLR-evoked fictive locomotion are shown. Similar format as Figure 1B. ○, control cycle periods without peripheral nerve stimulation; ▪, steps with Psoas 5T stimulation; ▴, steps with Sart 5T stimulation.
