68 patients was enrolled and randomly allocated into two groups: BES-SMFR group (n=34) and BES group (n=34). Every patient received 4 weeks treatment, and was evaluated at baseline (T0), 4-week post-intervention (T4) and 12-week follow-up (T12). The primary outcome was pain intensity. The secondary outcomes were degree in activation of MTrPs, surface electromyography (sEMG) levels, and Patient Global Impression of Improvement (PGI-I).
Myofascial pelvic pain (MFPP) caused by myofascial trigger points (MTrPs) is a major contributor of female chronic pelvic pain. However, the effect of the patient's self-myofascial release (SMFR) is not clear. Current study is to investigate the effect of SMFR combined with biofeedback and electrical stimulation (BES) therapy compared with BES alone in patients with MFPP.
