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.

A manual therapy technique that uses the gentle muscle contractions of the patient to relax and lengthen muscles and normalize joint motion.
It's also called the "positional release technique", a manual therapy technique that passively positions the hypertonic (spasmed) muscles and dysfunctional joints in positions of shortened or comfort.
SCS intervention that position with opposite site limb and direction, and with modified method as consider the easiness of a practitioner to press the tender points

Pain intensity in neck and masticatory muscles
ask participants the self-report pain intensity with the NPRS scale
Time frame: 4 weeks
Tenderness sensitivity in neck and masticatory muscles
measure the pressure pain threshold with digital pressure algometer
Time frame: 4 weeks
Maximal mouth-opening
measure the maximal pain free mouth-opening distance
Time frame: 4 weeks
Chewing endurance
test for 5 minutes with chewing gum in the affected site
Time frame: 4 weeks
Head-neck-shoulder posture
measure the Head tilt angle(HTA), Craniovertebral angle(CVA) \& Forward shoulder angle (FSA) by Photography in sagittal plane
Time frame: 4 weeks
