The aim of this study is to investigate the effects of an 8-week Pilates exercise program on pain, pressure-pain threshold, temporomandibular joint (TMJ) range of motion, cervical posture, stress levels, quality of life, jaw function and disability, depression, and muscle stiffness in women with myogenic temporomandibular disorders (TMD).
Eligible volunteers will be recruited from Toros University students and staff through screening with the Fonseca Anamnestic Index and diagnostic criteria for TMD (DC/TMD Axis I). After informed consent, participants who meet the inclusion criteria will be randomly assigned to either a control or an intervention group.
Control Group: Receives patient education (including information about parafunctional habits and sleep hygiene) and a standardized home exercise program to be performed three times per week for eight weeks. Compliance will be monitored weekly by phone calls and exercise logs.
Intervention Group: Receives the same education and home exercise program plus supervised Pilates training, three sessions per week for eight weeks, each lasting approximately 60 minutes (including warm-up and cool-down). Sessions are delivered by a certified physiotherapist and structured progressively every two weeks.
All participants will undergo a comprehensive baseline and post-intervention assessment by a blinded evaluator. Assessments include:
Pressure-pain threshold (digital algometer) at masseter, trapezius, and tibialis anterior muscles
Temporomandibular joint range of motion (TheraBite scale)
Cranio-cervical posture (photogrammetry and ImageJ analysis)
Pain intensity and disability (Visual Analog Scale, Graded Chronic Pain Scale)
Jaw function and limitation (JFLS-8)
Quality of life (SF-36)
Depression and anxiety levels (PHQ-4)
Muscle stiffness (MyotonPRO)
Salivary cortisol analysis for stress evaluation
Participants are excluded if they have systemic, neurological, psychiatric, or dental conditions; recent orthodontic treatment or trauma; ongoing use of pain medication; prior Pilates training in the past six months; or other factors that may affect assessment outcomes.
Data will be analyzed using SPSS (v26) with appropriate parametric and non-parametric tests, and statistical significance will be set at p<0.05. The study is designed as a single-blind, randomized controlled trial and will provide evidence on whether Pilates can be recommended as a complementary therapy in the management of myogenic TMD.
Inclusion Criteria:
Exclusion Criteria:
Participants in the experimental group will receive supervised Pilates training three times per week for eight weeks in addition to the patient education and home exercise program provided to the control group. They will first attend an introductory session covering core stabilization, pelvic alignment, breathing, and key Pilates principles, which they will be instructed to maintain throughout the exercises. Each 60-minute session will include a warm-up, progressive Pilates exercises performed in 3 sets of 10 repetitions, and a cool-down phase, with new movements introduced in weeks 3, 5, and 7. Exercises will be demonstrated, monitored, and corrected by a physiotherapist using verbal, tactile, and visual feedback.
Participants in the control group will receive patient education on avoiding parafunctional habits and maintaining proper sleep hygiene, along with a standardized home exercise program. The home program will include heat application, self-massage, jaw stretching, strengthening exercises, and Rocabado 6x6 exercises. They will be instructed to perform these exercises three times per week for eight weeks and will be contacted weekly to monitor compliance. An exercise log will be provided and collected at the end of the intervention period.
