Manual Therapy Effectivity and Exercises in Musicians

Study Overview
=================
Brief Summary
-----------------
Orofacial pain is one of the most common dysfunctions among wind musicians, a population with a high incidence of temporomandibular disorder (TMD). Regarding the treatment of TMD, the efficacy of manual therapy and therapeutic exercise has been studied, but there is a lack of high quality research supporting its implementation. There is, however, an agreement on the need of combining the treatment of the temporomandibular joint and the cervical spine, due to their close biomechanical relation. Aims of the study: To analyse the efficacy of an evidence-based manual therapy protocol alone or in combination with an exercise program on the treatment of orofacial pain during musical practice on wind musicians. Furthermore, this study aims at observing whether if said treatment is more effective in the short, medium, or long term, and which variables are the most influenced.

Detailed Description
-----------------
Methods: A sample of 40 wind musicians with orofacial pain during practice with the instrument will be recruited in the different conservatories of the Community of Madrid. The sample will be divided into two different groups: a control group who will receive the manual therapy protocol, and an experimental group who will, in addition, receive an exercise program. Treatment will consist of ten session distributed along 5 weeks, of an approximated duration of 30 minutes per session. Assessments will be carried out pre- and post-intervention, and for a two- and four-months follow-up.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Orofacial pain | Visual Analogic Scale.The pain VAS is a unidimensional measure of pain intensity, which has been widely used in diverse adult populations. The VAS is a straight horizontal line of fixed length, usually 100 mm. The ends are defined as the extreme limits of the parameter to be measured from 0 (no pain) to 10 (maximum pain). All the subjects will showed their pain level. | Change from baseline at 2 months | 
| Pressure Pain Threshold | An algometer Wagner FPI 10-WA will be used to determine the Pressure Pain Threshold in trigger points. | Change from baseline at 2 months | 
| Range of Temporo mandibular Movement | A vernier caliper will be used to measure mandibular movements. A vernier caliper is a validated tool to measure the opening, protusion, laterotrusion and overjet movements of the temporo mandibular joint | Change from baseline at 2 months | 
| cervical range of movement (CROM) | The instruments used to assess CROM will be a CROM goniometer. The CROM goniometer is a validated tool to measure the flexion, extension, rotation and tilt movements of the cervical spine. | Change from baseline at 2 months |
