Summary

This study is a multi-center survey of surface electromyography (sEMG) of pelvic floor muscles in healthy female. The aim of the study is to get the reference interval of normal pelvic floor sEMG from Chinese women.

Description

Pelvic floor dysfunction is a group of diseases caused by the damage of pelvic floor supporting structure. Pelvic floor muscles play an important role in the maintenance of pelvic floor function. Surface electromyography (sEMG) has been widely used to evaluate the function of pelvic floor muscles. The sEMG tests, which include pretest and posttest resting amplitude (V), as well as phasic, tonic and endurance contractile amplitude (V), are performed using Vishee neuro-muscle stimulator (MyoTrac Infiniti, model SA9800, Thought Technology Ltd., Montreal, Canada), following the Glazer protocols. A pear-shaped vaginal probe (serial number DYS180610, type VET-A, produced by Nanjing Vishee Medical Technology, Ltd.) is placed into the vagina when sEMG tests are performed. This is a cross-sectional survey. The reference intervals of pelvic floor sEMG in healthy female are evaluated.
