The goal of this clinical trial is to understand whether a simple education and self-management program with home exercises can reduce pain and improve daily function in adults with long-lasting jaw pain caused by temporomandibular disorders (TMD) as much as a more intensive hands-on physiotherapy approach.
The main questions it aims to answer are:
Researchers will compare an education and self-management program with home exercises to usual physiotherapy care to see which approach leads to better pain relief and daily functioning over time.
Participants will:
Attend three evaluation visits (at the start of the study, after 6 weeks, and after 16 weeks);
Be assigned to one of two treatment groups:
Participants will complete questionnaires about:
Jaw pain, Jaw function, Body pain, Neck disability, Oral behaviors, Pain catastrophizing, Fear of movement, Confidence in managing pain.
Measures of mouth opening will be taken (non-painful, maximal and maximal with assistance) with a ruler at all time points.
This study includes adults aged 18 to 65 years who have jaw pain for at least 3 months.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Patient education and self-management | Experimental | Each of the two sessions will be conducted individually with one of two physiotherapists and will last 45 minutes each. The first session will be used at baseline to deliver proper insights to the patient regarding normal physiology and their TMD, pain pathophysiology using references and visual aids (i.e. video, biomechanical demonstration on human skeleton model) to facilitate understanding. Depending on clinical presentation and scores to self-administered questionnaires, counseling and recommendations will be tailored. Lastly, an exercise program, including self-relief manual techniques and rehabilitation exercises for posture, mobility and strength of the neck and jaw will be demonstrated, practiced and prescribed to the participants (up to 5 exercises). At home, each patient will have access to an informational binder featuring the recommendations and prescribed exercise program to ensure patient's capacity to follow the intended program. |
|
| Usual treatment | Active Comparator | This group will be offered six (30 min, 1x/week) in-clinic PT-supervised sessions from one of two experienced physiotherapists over a 5-week period. The usual intervention group will receive personalized care tailored to each participant's presentation with the intention of reducing pain, increasing mobility and strength, and optimizing daily function. Care provided will not be standardized and will include a combination of manual therapy techniques, at-home exercises (up to 5 jointly chosen by PTs and participants) and education regarding potential contributing factors to the presenting TMD. Treatments will not only focus on the TMJ, but may also involve treatment for the neck, head and shoulder griddle based on the physiotherapist's expert clinical reasoning. All therapies will be documented for analysis. |

| Patient education and self-management | Behavioral | This intervention is a structured, patient-centered education and self-management program for adults with painful temporomandibular disorders (TMD). It is delivered one-on-one by a trained physiotherapist and focuses on improving understanding of jaw pain, reducing harmful oral habits, and restoring confident jaw movement. Participants receive individualized education about TMD, pain mechanisms, stress and habit influences, and practical strategies to manage daily activities such as chewing, speaking, posture, and sleep. The program addresses fear of movement and emphasizes safe, gradual jaw use. Each participant is given a personalized home exercise program targeting jaw and neck mobility, coordination, and muscle relaxation. Participants also set personal goals to support long-term self-management. |
| Measure | Description | Time Frame |
|---|---|---|
| Characteristic Pain Intensity (CPI) | Graded Chronic Pain Scale (version 2.0). This scale measures two subscales : the Characteristic Pain Intensity (CPI) and the Pain Interference. CPI is used to quantify a patient's jaw and face pain experience by averaging three scores from the past 6 months: current pain, average pain, and worst pain, on a 0-10 scale. The final score ranges from 0 to 100, with higher scores indicating more pain. | From enrollement to the last evaluation (at 16 weeks after the first treatment) |
| Pain Interference | Pain Interference (subscale of the GCPS 2.0) is assessed by measuring how pain restricts daily, social, family, and work activities over the past 30 days, using a 0-10 scale. The final score ranges from 0 to 100, with higher scores indicating greater pain interference. | From enrollement to the last evaluation (at 16 weeks after the first treatment) |
| Measure | Description | Time Frame |
|---|---|---|
| Jaw function | Jaw Functional Limitation Scale-20. This 20-item questionnaire used to assess mastication, vertical jaw mobility, and communication limitations, with total scores ranging from 0 to 200. Higher scores indicate greater functional limitations. | From enrollement to last evaluation (at 16 weeks after the first treatment) |
| Measure | Description | Time Frame |
|---|---|---|
| Central sensitization | Pain drawings will be completed by participants using a pen on paper method (round nib 1.5 mm) on body charts from axis II of the DC/TMD (body, face and jaw). The extent of body pain will be computer-analyzed. | From enrollment to last evaluation (at 16 weeks after the first treatment) |

| Usual treatment (multimodal) | Procedure | Usual care consists of a comprehensive physiotherapy program commonly used for adults with temporomandibular disorders (TMD). Treatment is delivered by a trained physiotherapist. Interventions may include hands-on manual therapy to reduce muscle tension, joint mobilizations to restore normal jaw movement, and supervised therapeutic exercises targeting jaw and neck mobility, coordination, and strength. Participants also receive education and advice regarding posture, oral habits, and daily activity modifications. Participants will have prescribed at-home therapeutic exercises (up to 5 jointly chosen by PT and patient). Participants will receive the same written booklet as the education and self-management arm. |

| Body Pain |
Brief Pain Inventory. This questionnaire uses a 0-10 numeric rating scale for 11 items, focusing on body pain severity and interference. It calculates two main scores: a 4-item Pain Severity Score (mean of worst, least, average, and current pain) and a 7-item Pain Interference Score (mean of disruption to daily life). The final scores for both pain and interference ranges from 0 to 10, where a higher score indicates greater pain or interference. |
| From enrollment to last evaluation (at 16 weeks after the first treatment) |
| Neck disability | Neck Disability Index (NDI) the NDI is a 10-section questionnaire assessing self-rated neck pain, with each section scored from 0 (no pain) to 5 (worst pain). The total raw score ranges from 0 to 50, where higher scores indicate greater disability related to the neck. | From enrollment to last evaluation (at 16 weeks after the first treatment) |
| Jaw mobility | A stainless steel ruler will be used to measure the jaw range of motion (opening, protrusion, laterotrusions). Measures will be taken in millimeters. | From enrollment to last evaluation (at 16 weeks after the first treatment) |
| Catastrophizing | Pain Catastrophizing Scale (PCS). The PCS is a 13-item tool assessing rumination, magnification, and helplessness regarding pain, using a 0-4 scale (0=never, 4=always). Total scores range from 0-52, with higher scores indicating greater catastrophizing. | From enrollment to last evaluation (at 16 weeks after the first treatment) |
| Kinesiophobia | Tampa Scale of Kinesiophobia (TSK-TMD). The TSK-TMD is a 17-item questionnaire (range 17-68) used to measure fear of movement and re-injury, with higher scores indicating greater fear. | From enrollment to last evaluation (at 16 weeks after the first treatment) |
| Self-efficacy | Patient Self-Efficacy Questionnaire-10 (PSEQ-10) The PSEQ-10 is a 10-item tool measuring a patient's confidence in performing activities despite pain. Items are rated on a 7-point scale (0 = "Not at all confident" to 6 = "Completely confident"), yielding a total score from 0-60. Higher scores indicate stronger self-efficacy. | From enrollment to last evaluation (at 16 weeks after the first treatment) |
| Oral Behaviors | Oral Behavior Checklist (OBC). The OBC is a 21-item questionnaire (2 sleep, 19 awake) that rates parafunctional habits on a 5-point Likert scale (0-4) over the past month, with total scores ranging from 0-84. A higher score indicates a higher risk of TMD related to oral behaviors. | From enrollement to last evaluation (at 16 weeks after the first treatment) |
Central Sensitization Inventory (CSI). The CSI consists of 25 items assessing symptoms of central sensitization, rated on a 5-point Likert scale (0=Never, 4=Always), totaling 0-100. A score of 40 or higher indicates the likely presence of a Central Sensitization Syndrome (CSS), with higher scores representing greater symptom severity. |
