Study Details

Study Description

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.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Muscle energy technique group Use one of the muscle energy technique methods -- postisometric relaxation technique(PIR) as the intervention method.	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.
Experimental: Strain-counterstrain group Use the Strain-counterstrain technique as the intervention method.	Behavioral: 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 Comparator: Control group Use the modified Strain-counterstrain technique as the intervention method.	Behavioral: 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 Measures

Primary Outcome Measures

1. Pain intensity in neck and masticatory muscles [4 weeks]

   ask participants the self-report pain intensity with the NPRS scale

2. Tenderness sensitivity in neck and masticatory muscles [4 weeks]

   measure the pressure pain threshold with digital pressure algometer

Secondary Outcome Measures

1. Maximal mouth-opening [4 weeks]

   measure the maximal pain free mouth-opening distance

2. Chewing endurance [4 weeks]

   test for 5 minutes with chewing gum in the affected site

3. Head-neck-shoulder posture [4 weeks]

   measure the Head tilt angle(HTA), Craniovertebral angle(CVA) & Forward shoulder angle (FSA) by Photography in sagittal plane
