Temporomandibular Joint Disorders, Neck Pain Musculoskeletal
Conditions
Brief summary
Temporomandibular disorders (TMD) are common musculoskeletal conditions affecting the jaw joint and surrounding chewing muscles. Myogenic TMD specifically involves muscle pain and dysfunction, which is frequently accompanied by chronic neck pain due to the close anatomical and neurophysiological connections between the jaw and the cervical spine. The purpose of this study is to compare the clinical effectiveness of two widely used physiotherapy interventions-a clinician-administered manual therapy protocol and a patient-conducted home exercise program-in individuals diagnosed with myogenic TMD and chronic neck pain. The main research question is to determine whether targeted manual therapy applied to both the temporomandibular and cervical regions yields superior improvements in pain, jaw and neck mobility, quality of life, and masseter muscle properties compared to the Rocabado 6x6 home exercise program alone. 1. A total of 34 participants aged 18-45 years with myogenic TMD and chronic neck pain will be randomly allocated into two equal groups: Manual Therapy Group: Participants receive 6 individual treatment sessions (3 days per week for 2 weeks) consisting of soft tissue mobilization, trigger point therapy, myofascial release, and joint mobilization techniques applied to the jaw and neck regions. 2. Exercise Group: Participants perform the standardized Rocabado 6x6 home exercise program 3 days per week for 2 weeks, with adherence monitored through daily exercise diaries. All participants undergo comprehensive assessments at baseline and immediately following the 2-week intervention. Evaluated parameters include jaw and neck pain intensity (Visual Analog Scale), cervical and mandibular range of motion, cervical joint position sense, jaw proprioception, facial asymmetry, bruxism, TMD severity, movement-related fear (kinesiophobia), and quality of life. In addition, masseter muscle thickness and elasticity are objectively assessed using ultrasound imaging and elastography. The findings of this trial aim to provide healthcare professionals with high-level evidence regarding effective, targeted physiotherapy strategies for managing myogenic TMD co-occurring with cervical pain.
Interventions
Clinician-administered targeted manual therapy protocol applied to both the temporomandibular joint and cervical spine regions. The treatment includes soft tissue mobilization, myofascial release, trigger point therapy, and joint mobilization techniques. Administered in 6 individual treatment sessions over 2 weeks (3 sessions per week).
Standardized patient-conducted Rocabado 6x6 home exercise program focusing on mandibular and cervical posture, mobility, and muscular control. Performed 3 days per week for 2 weeks. Patient adherence and compliance are tracked using daily exercise logbooks.

Masking description
The outcome assessor conducting baseline and post-treatment clinical and ultrasonographic evaluations is blinded to participant group allocations. Due to the nature of manual therapy and exercise interventions, participants and treating physiotherapists cannot be blinded. Data analysts and investigators involved in outcome calculations are also blinded to group assignments.
Eligibility
Inclusion criteria
* Presence of TMJ pain at rest, * TMJ pain persisting for at least 3 months, * Neck pain persisting for at least 3 months, * Willingness to participate in the study.
Exclusion criteria
