Temporomandibular joint (TMJ) disorder is a common condition characterized by pain and limited jaw mobility affecting up to 30% of the general population. Myofascial release (MFR) and mobilization are two manual therapies used to improve TMJ function. Maximum mouth opening (MMO) is a critical measure of TMJ function, with reduced MMO being a hallmark symptom of TMJ disorder. MMO can be measured using Open CV software. To compare the effects of Myofascial Release (MFR) and Mobilization on Maximum Mouth Opening (MMO) in patients with Temporomandibular Joint (TMJ) disorder, a total of 30 subjects with TMJ disorder and joint pain with restriction in jaw mobility were randomly selected for the study. The participants are adults aged 18-75years diagnosed with TMJ disorder. Exclusion criteria included a history of previous TMJ surgery and infections, history of trauma and fractures to the TMJ and surrounding structures, neurological and musculoskeletal conditions affecting the TMJ. The 15 individuals in each group into two groups GROUP A(MFR) GROUP B (MOBILISATION) for both groups pretest results from MMO, PAIN INTENSITY, JAW FUNCTION, ROM were assessed. Treatment interventions consisted of Both groups receiving 3–5 sessions per week for 4–6 weeks. MFR and mobilization are effective treatments for improving MMO in patients with TMJ disorder. However, MFR may be more effective in improving MMO and jaw function. Further research is needed to confirm these findings.
