This phase occurs after the action potential has passed and the muscle cell is no longer contracting. The other three phases of a skeletal muscle twitch are the latent period, the contraction phase, and the relaxation phase. corresponding author是什么作者WebThe local twitch response (LTR) is triggered by a sudden change in pressure over a MTrP. The presence of an LTR indicates the likelihood of a MTrP in the examined muscle. LTR is a rapid reflexive contraction of the muscle fibers in a taut band associated with a MTrP as the therapist's fingers snap perpendicularly across the taut band. corresponding author 翻译
