Excitability testing during wrist flexion-extension task. A: ADVs in SR induced by ISMS of a single intraspinal site in each behavioral epoch during flexion trials; stimulus time is at the left of the traces. Two distinct volleys (gray lines) were apparent in all behavioral epochs. B and C: mean ± SE of the amplitude of ADVs with earlier (B) and later (C) latencies in each behavioral epoch. *Significant difference relative to rest (P < 0.05). Number of responses averaged for each trace is shown in parentheses.
