Description

Study design Analytical, prospective experimental study: uncontrolled clinical trial.

Population and study sample The study sample will be made up of subjects diagnosed with fibromyalgia who present with local myalgia, myofascial pain or referred myofascial pain in the temporomandibular region, according to the diagnostic criteria (DC/TMD). The subjects will be recruited after the mandatory acceptance and authorization by the corresponding bodies, during a recruitment period of approximately eight weeks, through different associations of fibromyalgia patients.

Intervention In a first visit, demographic data will be recorded and an examination will be performed to assess the presence of local myalgia, myofascial pain or referred myofascial pain in the temporomandibular region, according to the diagnostic criteria (DC/TMD). You will also be given, to read and sign, the informed consent for participation in the study, as well as the data protection document. After this visit, the defined eligibility criteria (inclusion and exclusion) will be applied.

In a second visit, a preliminary assessment will be carried out that will consist of measuring the maximum oral opening with and without pain, pressure pain threshold in the temporomandibular joint and masseter and temporal muscles, and the level of pain in the temporomandibular joint. In addition, the subject will have to fill out a questionnaire on different aspects such as jaw function, quality of life related to oral health, kinesiophobia, anxiety and depression, sleep, patient expectations, patient habits, catastrophizing, knowledge about pain, central sensitization , self-efficacy, and coping with pain.

One week later, the intervention program will begin. The program will consist of 3 sessions (visits 3, 4 and 5) in which everything related to pain and its management will be explained. In a first workshop, a first educational session on the neurophysiology of pain will be given by means of a Power point presentation. In a second workshop, a tool will be used to locate those factors that can improve/worse the pain, physical documentation will be delivered with instructions for performing a self-massage and exercises of the temporomandibular region as well as advice and recommendations to manage different situations that may appear on a daily basis and on Lifestyle. A meditation session will also be held. In the third and last workshop, the game "the painometer" will be played and a meditation session will be held.

On a sixth visit, 4 weeks after the end of the program, a new measurement and assessment will be taken. This measurement will be very similar to the one performed on the second visit, except for 1 variable: the patient's expectations will not be recorded, and the patient's satisfaction with the treatment received will be recorded. The objective will be to record the changes produced after the application of the treatment program.

On a seventh visit, at 6 months (medium-term follow-up), all the measurements and assessments made on the sixth visit will be repeated, with the aim of recording their status after six months.

At an eighth visit, at 12 months (long-term follow-up), all the measurements and assessments made at the seventh visit will be repeated, with the aim of recording their status after twelve months.
