Impact of electrical muscle stimulation-induced muscle contractions on endogenous pain modulatory system: a quantitative sensory testing evaluation.

ABSTRACT:

Background

Exercise-induced hypoalgesia (EIH) is characterized by a reduction in pain perception and sensitivity across both exercising and non-exercising body parts during and after a single bout of exercise. EIH is mediated through central and peripheral mechanisms; however, the specific effect of muscle contraction alone on EIH remains unclear. Moreover, previous studies on electrical muscle stimulation (EMS) have primarily focused on local analgesic effects, often relying on subjective pain reports. This study investigated the contribution of EMS-induced muscle contractions to systemic analgesia, independent of motor cortex activity. We aimed to explore the underlying mechanisms of EIH by analyzing the influence of skeletal muscle mass (SMM), skeletal muscle mass index (SMI), a
