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.

Conditions

Myogenous Temporomandibular Disorders (mTMD)

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: SEQUENTIAL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

Muscle energy technique group

Use one of the muscle energy technique methods -- postisometric relaxation technique(PIR) as the intervention method.

Group Type: EXPERIMENTAL

Muscle energy technique (MET)

Intervention Type: BEHAVIORAL

A manual therapy technique that uses the gentle muscle contractions of the patient to relax and lengthen muscles and normalize joint motion.

Strain-counterstrain group

Use the Strain-counterstrain technique as the intervention method.

Group Type: EXPERIMENTAL

Strain-counterstrain (SCS)

Intervention Type: BEHAVIORAL

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.

Control group

Use the modified Strain-counterstrain technique as the intervention method.

Group Type: SHAM_COMPARATOR

sham SCS

Intervention Type: BEHAVIORAL

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
