RATIONALE OF THE OBSERVATION STUDY: This study aims to observe which patients with temporomandibular disorder improve more following a physiotherapy program of four sessions. Knowing the characteristics of patients who have the most significant improvements could help clinician advise or advise against physiotherapy for the treatment of temporomandibular disorders. STUDY PROCEDURES The study will be conducted at the Istituto Stomatologico Italiano. Patients diagnosed with Temporomandibular Disorder will be recruited in the gnathological and neuromuscular gnathological departments. The physiotherapists of the Craniomandibular Physiotherapy Service will perform physiotherapy therapy, which consists of four physiotherapy sessions \[lasting 30 minutes, about once a week\] over a month. Before starting the treatment, participants will be asked to answer some questions concerning their state of health (e.g. pain intensity) with particular reference to Temporomandibular Disorder (e.g. location and duration of pain). The intensity of pain and the level of function will then be monitored at baseline, after 4 weeks and after 8 weeks from baseline. EXPECTED BENEFITS FROM THE STUDY AND EXPECTED BENEFITS FOR THE PATIENT The benefits are the discovery of new knowledge in the field of therapeutic choice for patients with temporomandibular disorder.
Additional information: In this study protocol, the variables reported in the section "Other Pre-specified Outcomes" are the predictors that will be included in the prediction model. The total "Enrollment" is 180 participants (100 for the development phase and 80 for the validation phase).
Study Type
OBSERVATIONAL
Enrollment
180
Participants will receive four sessions of manual therapy applied to craniomandibular structures over four weeks. The application of manual therapy aims to decrease pain by treating masticatory muscle trigger points, muscle tightness, and restricted temporomandibular joint movements. Several techniques will be considered, including ventral and caudal anterior glide temporomandibular joint mobilisation, soft tissue interventions for the management of trigger points in masticatory muscles and myofascial induction therapy applied to craniomandibular structures. The structures targeted in the treatment sessions will be the temporomandibular joint, temporal muscles, masseter muscles, medial and lateral pterygoid muscles and suprahyoid muscles.

Change in Pain Intensity (Visual Analogue Scale [VAS]) from baseline to one month
Pain intensity will be calculated by averaging the ratings of current pain, average pain in the past week, and worst pain in the past week using the Visual Analogue Scale (VAS), consisting of a horizontal line measuring 10 cm (without marks), with "no pain" written at the left extremity, and "worst pain imaginable" at the right extremity. Patients will be educated to trace a perpendicular line on the horizontal line to intend the pain intensity. The distance from the 0 points will be after measured in millimetres. The VAS is a reliable and valid scale to assess pain intensity as an outcome measure in intervention studies. Based on the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) recommendations about TMD , a reduction of at least 30% of the VAS score for pain intensity is considered clinically significant. Consequently, a reduction in the total VAS score \[≥ 30%\] will be defined as a good outcome

Change in Function (patient specific functional scale [PSFS]) from baseline to one month
To capture a potential change in function, patients will also complete the patient specific functional scale (PSFS). The PSFS is a self reported outcome measure assessing functional change in patients with musculoskeletal disorders. It is responsive to clinically significant change over time, even in chronic pain patients. Patients are invited to rate, on an 11-point scale, their level of difficulty performing at least three different daily activities. Following the treatment, patients are required to score again the activities previously rated. It is known the PSFS is a valid, reliable, and responsive outcome measure with a high test-retest reliability in patients with lower back pain and knee problems.
