Generalization of SR attenuation. A: example of flexor stretch reflex (SR) response (arrow) and the inhibitory period (IP) from one of the trials in which SRs were attenuated. B: after a 3 to 5 min rest period, originally non-stretched extensors began to be stretched. Extensor SR was immediately suppressed (arrow) without preliminary trials of stretching. C and D: a similar effect of flexor SR suppression was observed after previous suppression of extensor SRs. E and F: group data— antagonist SRs were suppressed without preliminary attenuation if SRs of agonist muscles were suppressed during repeated stretches before a 3 to 5 min rest period. Calibration bars for EMG signals: 100μV (A and B) and 200 μV (C and D). Reproduced with permission from Turpin et al. (2016). Copyright Springer.
