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

Not Applicable

Completed

• Conditions: Myogenous Temporomandibular Disorders (mTMD)
• Interventions: Behavioral: Strain-counterstrain (SCS); Behavioral: sham SCS; Behavioral: Muscle energy technique (MET)

• Registration Number: NCT04704102
• Lead Sponsor: Chang Gung University

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.

Arm && Interventions

Group	Intervention	Description
Strain-counterstrain group	Strain-counterstrain (SCS)	Use the Strain-counterstrain technique as the intervention method.
Control group	sham SCS	Use the modified Strain-counterstrain technique as the intervention method.
Muscle energy technique group	Muscle energy technique (MET)	Use one of the muscle energy technique methods -- postisometric relaxation technique(PIR) as the intervention method.

Primary Outcome Measures

Name	Time	Method
Tenderness sensitivity in neck and masticatory muscles	4 weeks	measure the pressure pain threshold with digital pressure algometer
Pain intensity in neck and masticatory muscles	4 weeks	ask participants the self-report pain intensity with the NPRS scale

Secondary Outcome Measures

Name	Time	Method
Head-neck-shoulder posture	4 weeks	measure the Head tilt angle(HTA), Craniovertebral angle(CVA) \& Forward shoulder angle (FSA) by Photography in sagittal plane
Maximal mouth-opening	4 weeks	measure the maximal pain free mouth-opening distance
Chewing endurance	4 weeks	test for 5 minutes with chewing gum in the affected site
