Effects of Soft Tissue Mobilization of Neck Muscles in Individuals With Myogenous Temporomandibular Disorders: Muscle Energy Technique and Strain-counterstrain

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.

  • Tooth implantation or extraction a week before study
  • Vertebrobasilar insufficiency

Treatment and study plan

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.

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.

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

Primary outcomes

  1. Pain intensity in neck and masticatory muscles

    Time frame: 4 weeks

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

  2. Tenderness sensitivity in neck and masticatory muscles

    Time frame: 4 weeks

    measure the pressure pain threshold with digital pressure algometer

Secondary outcomes

  1. Maximal mouth-opening

    Time frame: 4 weeks

    measure the maximal pain free mouth-opening distance

  2. Chewing endurance

    Time frame: 4 weeks

    test for 5 minutes with chewing gum in the affected site

  3. Head-neck-shoulder posture

    Time frame: 4 weeks

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