Effect of Virtual Reality on TMD Following Maxillofacial Surgery

Sixty eight patients who have TMJ pain and ROM restriction after maxillofacial surgery participated in this study , they are selected from government hospitals (general and insurance ).

Will be randomly divided into two equal groups ( group A, group B ). Their ages range from 20 - 35 years.

The VR glasses which were the source of visual and auditory feedback, were connected by Bluetooth to a mobile phone and all the videos of selected tasks (tasks of Active mobility exercises and isometric contraction exercises, massage exercises) were turned on. Active mobility exercises (jaw opening 6 times of 30 s; lateralization 10 times of 5 s; protrusion 10 times Of 5 s).

• Self-massage masticatory Muscles, After each session.
• Isometric contraction exercises The Purpose of the study is to evaluate the therapeutic efficacy of VR in decreasing pain and improve ROM for Patients after maxillofacial surgery.
