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)

Keywords

myogenous temporomandibular disorders, neck pain, muscle energy technique, strain-counterstrain, head-neck posture

Outcome Measures

Primary Outcomes (2)

• Pain intensity in neck and masticatory muscles

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

  4 weeks

• Tenderness sensitivity in neck and masticatory muscles

  measure the pressure pain threshold with digital pressure algometer

  4 weeks

Secondary Outcomes (3)

• Maximal mouth-opening

  4 weeks

• Chewing endurance

  4 weeks

• Head-neck-shoulder posture

  4 weeks

Study Arms (3)

Muscle energy technique group

EXPERIMENTAL

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

Behavioral: Muscle energy technique (MET)

Strain-counterstrain group

EXPERIMENTAL

Use the Strain-counterstrain technique as the intervention method.

Behavioral: Strain-counterstrain (SCS)

Control group

SHAM COMPARATOR

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

Behavioral: sham SCS

Interventions

Muscle energy technique (MET) BEHAVIORAL

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

Muscle energy technique group

Strain-counterstrain (SCS) 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.

Strain-counterstrain group

sham SCS 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

Control group
