Figure 2. Effect of conditioning the flexor carpi radialis H-reflex with radial nerve stimulation during leg cycling and static activation.

(A) Typical averaged recordings of conditioned (black lines) and unconditioned (gray lines) H-reflex waveforms during static (upper traces) and cycling (lower traces) tasks obtained from a single subject. Grand means and SEM of magnitudes of the pre-stimulus EMG (B), H-reflex (C) and M-wave (D) during conditioned (black bars) and unconditioned (gray bars) trials. *p<0.01 significantly different from the unconditioned values for each task. +p<0.01 significantly different from the unconditioned static value.
