Impact of extension restraint on EMG activity during RLMs at E20. Impact of extension restraint on EMG activity during RLMs at E20. Leg EMG and joint excursions are plotted for two RLMs from the same experiment during control (A) and ankle restraint (B). (A) During control, ankle flexor (TA) EMG was rhythmically active and intermittently accompanied by bursts in both the ankle extensor (LG) and knee extensor (FT). (B) During extension restraint, the TA was rhythmically active but bursts were longer in duration and larger in amplitude. In addition, FT and LG activity dropped out. Maximum joint excursion range was not different between conditions. Nina S. Bradley et al. J Exp Biol 2014;217:896-907 © 2014. Published by The Company of Biologists Ltd
