Post-Isometric Relaxation in Temporomandibular Disorders
Sponsor: Sanem ŞENER
Summary
This planned randomized, single-blind clinical trial will investigate the effects of adding the Post-Isometric Relaxation (PIR) technique to a standard postural exercise program in individuals with moderate to severe temporomandibular joint dysfunction (TMD). Forty volunteers aged 18-25 years will be recruited and randomly assigned to either an experimental group (postural exercises + PIR) or a control group (postural exercises only). The intervention will be delivered three times per week for six weeks. Primary outcomes will include cervical range of motion, mandibular mobility, head anterior tilt, and thoracic kyphosis index, measured before and after the intervention. The study aims to determine whether PIR provides additional benefits to standard postural exercises in improving jaw and neck function and postural alignment in young adults with TMD.

Interventions
Postural Exercises + Post-Isometric Relaxation (PIR) Technique
Participants will perform a standardized postural exercise program (strengthening, stretching, and mobility exercises for the cervical and thoracic regions) three times per week for six weeks. In addition, the Post-Isometric Relaxation (PIR) technique will be applied to jaw muscles during each session to reduce muscle tension and improve mandibular mobility.
Postural Exercises
Participants will perform a standardized postural exercise program designed to improve cervical and thoracic mobility and postural alignment. The program will include strengthening, stretching, and mobility exercises targeting the cervical spine, thoracic spine, and related musculature. Each session will last approximately 30-40 minutes and will be conducted three times per week for six weeks under the supervision of a trained therapist.
