Study Overview
Brief Summary
This is a prospective case series study.There were 20 individuals with chronic neck pain accompanied by myogenous temporomandibular disorders(mTMD) from Linkou and Taoyuan Chang Gung hospitals, and Chang-Gung university. The purpose of this study was, first, to investigate the effects of muscle energy technique (MET) or strain-counterstrain (SCS) applied on the tender or trigger points of neck muscles on improving pain and pressure pain sensitivity in neck and masticatory muscles, the maximal mouth-opening range of motion, chewing endurance, and head-neck-shoulder posture in patients with chronic neck pain accompanied by mTMD. Second, whether the significant effects could be reached within the four-week intervention duration.
