Effectiveness of Cervical Treatment in Wind Musicians With Temporomandibular Dysfunction

Study Overview
=================
Brief Summary
-----------------
Temporomandibular dysfunction (TMD) consists of a series of multifactorial signs and symptoms that occur in the orofacial region, with pain being the most common symptom. There is a close biomechanical and anatomical relationship between the cervical region and the temporomandibular joint (TMJ) through the trigemino-spinal nucleus. Objectives: To comparatively assess the improvement in subjects with TMD when adding cervical manual therapy to a postural treatment. Additionally, to determine if both cervical treatments separately produce changes in the TMJ. Materials and methods: An experimental study of randomized controlled clinical trial type was conducted. The study involved 30 wind instrument players randomly assigned to an experimental group (EG) and a control group (CG). After obtaining consent, measurements were taken for maximum mouth opening (MMO), cervical range of motion, and pain threshold to pressure (PTP) in the masseter and temporalis muscles. Both groups underwent active cervical postural treatment for 4 weeks, and the EG additionally received a cervical manual therapy protocol. An initial assessment was conducted before the intervention, and a final assessment was done one week after the last intervention. The statistical program SPSS was used for data analysis.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Protocol group<br>The treatment plan includes active postural exercises for the cervical spine. | Other: Postural exercises<br>* The treatment plan includes active postural exercises for the cervical spine.<br>|
| Experimental: Manual therapy group<br>The treatment plan includes active postural exercises and manual therapy for the cervical spine. | Other: Manual therapy<br>* Within the manual therapy protocol carried out in the experimental group, we performed a series of passive maneuvers. The patient remains in supine position on a treatment table throughout the treatment, while the therapist sits at the head of the patient on a stool. The sequence of application is as follows: Suboccipital inhibition technique Cervical spinal mobilization Posterior fascia stretching<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Cranio facial pain and disability inventory | CF-PDI (Craniofacial Pain and Disability Inventory): This questionnaire focuses on pain as a common symptom of TMD (Temporomandibular Disorders). It is self-administered and designed to assess patients' perception of their physical and psychosocial health in relation to craniofacial pain. It consists of 21 questions regarding the impact of pain on activities involving the use of the temporomandibular joint, with a scoring range from 0 to 63 in ascending order, where 0 indicates no impact and 63 indicates maximum impact. This questionnaire demonstrates good structure, internal consistency, reproducibility, and validity, making it an objective tool that can be used in research and clinical practice for evaluating patients with craniofacial pain and disability. It is easy to administer and requires a short amount of time. The CF-PDI was created and developed in Spain, based on a biopsychosocial approach. | a week after treatment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum mouth opening. | The measurement of maximum mouth opening (MMO) is the distance in centimeters between the upper and lower incisor teeth when the subject actively opens their mouth. | a week after treatment |
