Overview
Brief Summary
This randomized controlled trial will be conducted among 18-25-year-old participants who present with temporomandibular joint dysfunction symptoms, including pain, limited range of motion, and joint crepitation. Participants will be randomly allocated into control and intervention groups using block randomization. The control group will receive a standard physiotherapy program, while the intervention group will additionally perform telerehabilitation-based dual-task exercises. The intervention will last for six weeks, with progressive increases in exercise and cognitive task difficulty. Outcomes will be assessed at baseline and at the end of the 6th week. Primary and secondary outcome measures include pain intensity (Visual Analog Scale), jaw functional limitation (Jaw Functional Limitation Scale-20), oral habits, static balance (Tetrax system), and dynamic balance (Timed Up and Go Test). Within-group and between-group comparisons will be performed. The sample size was calculated using power analysis, resulting in 30 participants in total (15 per group), accounting for potential dropouts.

Masking Description
Due to the nature of the interventions, participants and care providers cannot be blinded to group allocation. However, outcome assessors will be blinded to participant group assignment to minimize assessment bias. In addition, data analysts will be blinded by using coded group labels during statistical analysis to further reduce potential bias.

Outcomes
Primary Outcomes
Pain Intensity
Time Frame: Measurements will be recorded at baseline and at week 6. Change in pain intensity will be analyzed.
Pain intensity will be assessed using a 10-cm Visual Analog Scale. Participants will rate their pain at rest, during chewing, and at night. Scores range from 0 (no pain) to 10 (worst imaginable pain).
Jaw Functional Limitation
Time Frame: Assessments will be performed at baseline and week 6.
(Jaw Functional Limitation Scale - JFLS-20): Jaw function will be evaluated using the JFLS-20, a 20-item self-report scale assessing functional limitations in mastication, speech, and jaw movement. Each item is scored from 0 (no limitation) to 10 (severe limitation). Higher scores indicate greater functional impairment.
Secondary Outcomes
- Temporomandibular Disorder Classification(Assessment will be performed at baseline.)
- Oral Habits(Assessments will be performed at baseline and week 6.)
- Dynamic Balance(Assessments will be performed at baseline and week 6.)
- Stability Index (SI)(Baseline and after 6 weeks)
- Weight Distribution Index (WDI)(Baseline and after 6 weeks)
- Fourier Harmonic Index (FHI)(Baseline and after 6 weeks)
- Fall Index(Baseline and after 6 weeks)
