The Effectiveness of a Physiotherapy Technique in Patients With Chronic Myofascial Temporomandibular Disorder

Not Applicable

Completed

Conditions: Myofascial Pain Syndrome
Temporomandibular Disorder

Registration Number: NCT03619889

Lead Sponsor: Universidad Complutense de Madrid

Brief Summary: Participants with chronic orofacial pain caused by masticatory and neck muscles will be distributed in two groups, both followed with the same occlusal and self-care treatment. The experimental group will receive 5 sessions of physiotherapy applying a specific pressure on the trigger points while the control group will receive placebo through a simulation of the same technique. Orofacial perceived pain, pain pressure thresholds, catastrophizing, kinesiophobia, cervical disability, depression and anxiety will be evaluated at baseline, immediately after treatment and 3 months later.

Primary Outcome Measures

Name	Time	Method
Changes of Perceived Pain Between Three Time Points (Baseline, Post-treatment, and 3 Months Later) and Between Groups (Sham Simulation and Pressure Release Technique)	Change from baseline in the scale at post-treatment and at 3 months later	The Visual Analogue Scale (0-10) was used, 0 representing no pain/better outcome, and 10 representing unbearable pain/worst outcome. the clinical minimum relevance outcome is at least a change of 1.2 points in the scale.

Secondary Outcome Measures

Name	Time	Method
Changes in the Neck Disability	Change from baseline in the scale at post-treatment and at 3 months later	The Neck Disability Index was used (0-50), with 0 representing no disability neck/best outcome and 50 maximum disability neck/worst outcome.
Changes of Pain Pressure Thresholds Sternal Sternocleidomastoid	Change from baseline in the scale at post-treatment and at 3 months later	An algometer Wagner Force One FDX 50 was used, measured in kgf/cm\^2, with 0 representing the lowest pain pressure threshold/worst outcome and as higher pain pressure threshold/ as a better outcome.
Changes in the Kinesiophobia	Change from baseline in the scale at post-treatment and at 3 months later	The Tampa Scale for Kinesiophobia -11 was used (0-44), with 0 representing no kinesiophobia/best outcome and 44 representing the highest level of kinesiphobia/worst outcome.
Changes in the Trait Anxiety	Change from baseline in the scale at post-treatment and at 3 months later	The State-Trait Anxiety Index was used, lower values represent a better outcome. State and Trait were evaluated individually, range of scores for each subtest is 20-80, with 20 representing no trait anxiety/best outcome and 80 representing the highest level of trait anxiety/worst outcome.
Changes in the Range of the Opening of the Mouth	Change from baseline in the scale at post-treatment and at 3 months later	A calibrator Dentaurum München was used, measured in millimetres, with 0 representing no opening/worst outcome and as higher values/as a better outcome.
Changes in the Catastrophizing	Change from baseline in the scale at post-treatment and at 3 months later	The Pain Catastrophizing Scale was used (0-52), with 0 representing no catastrophizing/best outcome and 52 representing the highest level of catastrophizing/worst outcome.
Changes in the State Anxiety	Change from baseline in the scale at post-treatment and at 3 months later	The State-Trait Anxiety Index was used, lower values represent a better outcome. State and Trait were evaluated individually, range of scores for each subtest is 20-80, with 20 representing no state anxiety/best outcome and 80 representing the highest level of state anxiety/worst outcome.
Changes of Pain Pressure Thresholds Superficial Masseter	Change from baseline in the scale at post-treatment and at 3 months later	An algometer Wagner Force One FDX 50 was used, measured in kgf/cm\^2, with 0 representing the lowest pain pressure threshold/worst outcome and as higher pain pressure threshold/ as a better outcome.
Changes of Pain Pressure Thresholds Anterior Temporalis	Change from baseline in the scale at post-treatment and at 3 months later	An algometer Wagner Force One FDX 50 was used, measured in kgf/cm\^2, with 0 representing the lowest pain pressure threshold/worst outcome and as higher pain pressure threshold/ as a better outcome.
Changes in the State Depression	Change from baseline in the scale at post-treatment and at 3 months later	The State-Trait Depression Inventory was used, lower values represent a better outcome. State and Trait were evaluated individually, range of scores for each subtest is 20-80, with 20 representing no state depression/best outcome and 80 representing the highest level of state depression/worst outcome
Changes in the Trait Depression	Change from baseline in the scale at post-treatment and at 3 months later	The State-Trait Depression Inventory was used, lower values represent a better outcome. State and Trait were evaluated individually, range of scores for each subtest is 20-80, with 20 representing no Trait Depression/best outcome and 80 representing the highest level of Trait Depression/worst outcome
Changes of Pain Pressure Thresholds Upper Trapezius	Change from baseline in the scale at post-treatment and at 3 months later	An algometer Wagner Force One FDX 50 was used, measured in kgf/cm\^2, with 0 representing the lowest pain pressure threshold/worst outcome and as higher pain pressure threshold/ as a better outcome.
