Summary

The goal of this clinical trial is to compare effects of Rocabado exercises which is conventional physiotherapy treatment alone vs. combine it with proprioceptive neuromuscular facilitation (PNF) in people with temporomandibular dysfunction (TMD) with forward head posture. The main question aims to answer: \- Does adding neck and jaw PNF techniques to the treatment affect the pain and functional status of the jaw compared to Rocabado exercises alone? Participants will be randomized into two groups (Group 1: only Rocabado exercises, Group 2: Rocabado + PNF) and perform 8 weeks long exercises. They will be assessed in the beginning of the study and at the end of the 8th week.

Detailed description

Infrared heat will be applied to the neck and face areas for 15 minutes for individuals with TMD with forward head posture in both groups. Then Group 1 will perform Rocabado exercises only, and Group 2 will perform PNF exercises in addition to Rocabado exercises. Exercises will be demonstrated and applied by a physiotherapist at the university clinic. Pain intensity, pain threshold, TMJ functions, joint range of motion and Mandibular Function are among the parameters to be evaluated. All evaluations will be made by a blinded evaluator at baseline (baseline t=0), before exercise and after exercise (post-exercise, t=8.week).

Conditions

• TMD
• TMJ Disorder
• Pain

Interventions

Type	Name	Description
OTHER	Rocabado's 6x6 Exercises	Rocabado's 6x6 program includes 6 basic components: tongue rest position, TMJ rotation control, cervical spine release, shoulder girdle retraction and rhythmic stabilization technique.
OTHER	PNF Exercises	Proprioceptive neuromuscular facilitation (PNF) exercises will be applied to the neck and jaw with rhythmic stabilization (RS) and combined isotonic contraction (CIC) techniques. The RS protocol consists of alternating isometric contractions for 10 seconds and does not involve movement. The KIK technique involves combined concentric, isometric and eccentric contraction of the agonist muscle without rest, with each contraction lasting 5 seconds. KIK exercises consist of 5-15 repetitions per set, depending on the individual's tolerance. Between sets, a 30-second rest will be included. First, the RS protocol will be applied and after a 2-minute rest interval, the exercise will continue with the KIK protocol applications. The expected duration of exercise exercises is 30 minutes. Maximum performance will be requested from the individual in all repetitions and the necessary verbal commands will be given for appropriate movement.
