Clinical Trial 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.

• Disease
• Myogenous Temporomandibular Disorders (mTMD)
• Temporomandibular Joint Disorders
• Temporomandibular Joint Dysfunction Syndrome

Intervention

Behavioral:
• Muscle energy technique (MET)
A manual therapy technique that uses the gentle muscle contractions of the patient to relax and lengthen muscles and normalize joint motion.
• Strain-counterstrain (SCS)
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.
• sham SCS
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

Outcome

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