Plain-language summary
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.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
