A Combined Treatment of Manual Therapy and Nervous Vagus Stimulation in Patients With Myogenic Temporomandibular Disorders
A Combined Treatment of Manual Therapy and Nervous Vagus Stimulation Versus a Treatment of Manual Therapy Isolated in Patients With Myogenic Temporomandibular Disorders
Temporomandibular disorders (TMD) are one of the most important Public Health issues in the world and its incidence has increased over the years. The Physiotherapy and manual therapy techniques has shown its efficacy to reduce pain and to improve jaw functionality in patients with TMD. Until now, treatment targets has been the muscle and joint, but clinicians has not taken into account the innervation and how the nerve can have an influence in pain or jaw functionality.
In this sense, it is known that there is a relationship between jaw innervation and vagus nerve, a parasympathetic nerve which is easily stimulable, due to its connection with the respiratory system, taking deep breaths using the diaphragm.
Therefore, our hypothesis is that a treatment in which clinicians combine manual therapy and nerve vagus stimulation could have better effects (reducing pain, increasing range of motion in temporomandibular joints and improving quality of life in patients with TMD) than a isolated manual therapy treatment.
With this purpose will be selected 20 subjects to participate in our study divided in two groups. Both groups will received 4 sessions of physiotherapy (one each 7 days during one month) and also will be thought to do own treatment those days the subjects does not come to the clinic until the study will have finished (the interventional period last two months). Both groups will received the same manual therapy techniques but only the experimental group will be treated with nerve vagus stimulation technique.
One member of the group who will not participated in the interventions will be in charge of do evaluations (1 each month/ a total of 3 evaluations) following different questionaries to assess the primary variables of the study: chronic pain level, jaw functionality, physical symptoms level, range of motion and distress level.

Detailed Description
The aim of the study is to check whether vagus nerve stimulation (VNS) combined with manual therapy (TM), given its neuroanatomical relationship with the structures involved in pain in the TMJ, is more effective in reducing pain, increasing joint range and increasing the quality ofthe patient lives than TM alone.
The research team is made up of three physiotherapists. It has been decided to distribute the tasks as follows:
- Physiotherapist 1 will be in charge of the treatment of all patients.
- Physiotherapist 2 will be responsible for screening the sample and evaluating the study.
- Physiotherapist 3 will be in charge of analyzing the results and statistics. This component of the team, being blinded and not knowing the group of origin of the patient, will be able to interpret the results without any type of convenience bias, showing absolutely transparency in the elaboration of the conclusions.
Once the screening will be completed, the patients will be divided into two groups: an experimental group (TM + ENV) and a control group (TM + ENV placebo).The randomization will be carried out through the statistical program Epidat 4,237 9 obtaining two homogeneous groups. Each patient will be assigned a code with the aim that the physiotherapist who is in charge of the statistical analysis is not able to establish links between the data and the subjects to which it refers.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Patient´s state of health
Time Frame: Change from baseline at 2 months
|
An interpretation of the improvement of patient´s state of health related with temporomandibular disorders taking into account other improvements in differents areas/variables which will be described as secondary outcomes

Graded Chronic Pain Scale (CPGS)
Time Frame: Change from baseline at 2 months
|
The CPGS is a multidimensional measure that assesses 2 dimensions of overall chronic pain severity: pain intensity and pain-related disability.
It is suitable for use in all chronic pain conditions.The 3 subscale scores (characteristic pain intensity, disability score, and the disability points score) are used to classify subjects into 1 of the 5 pain severity grades: grade 0 for no pain, grade I for low disability-low intensity, grade II for low disability-high intensity, grade III for high disability-moderately limiting, and grade IV for high disability-severely limiting.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Range of motion (Opening without pain, Maximum Opening, Lateral movements and Protrusion movement)
Time Frame: Change from baseline at 2 months
|
All of them were measured in millimeters using a rule.
The evaluator take 3 measures of each movement and the final outcome was the average of these 3 measures.
|
Change from baseline at 2 months
|
Jaw Functional Limitation Scale
Time Frame: Change from baseline at 2 months
|
The JFLS-20 is a scale that assesses the limitation of jaw function during chewing, mobility, and verbal and non-verbal communication.The maximum score is 20.
Lower scores denote lower aw functional limitation and higher scores denote higher jaw functional limitation.
|
Change from baseline at 2 months
|
The Patient Health Questionnaire (PHQ-15)
Time Frame: Change from baseline at 2 months
|
The PHQ-15 is comprised of 15 items and assesses non-specific physical symptoms, also referred to as functional symptoms or medically unexplained symptoms.PHQ-15 scores of 5, 10, 15, represented cutoff points for low, medium, and high somatic symptom severity, respectively
|
Change from baseline at 2 months
|
Distress Level PHQ-4
Time Frame: Change from baseline at 2 months
|
This one was assesed using PHQ-4.
The PHQ-4 is comprised of two 2-item subscales, anxiety and depression, and it is intended to be an ultrabrief screener for distress as the composite construct of anxiety and depression.Total scores range from 0 to 12, with higher scores indicating greater psychological distress
