Outcomes of physical therapy in patients with temporomandibular disorder: a retrospective review.

Temporomandibular disorder (TMD) encompasses a spectrum of disorders that are associated with pain in the temporomandibular joint (TMJ) and surrounding musculature. Current research shows that conservative physical therapy is beneficial in the management of the disorder. This study further explores if physical therapy is an effective approach to treating patients with TMJ disorders. Our objectives were to determine the effect of conservative physical therapy interventions on pain, maximal mouth opening, and TMJ disability index for patients with TMD. Medical records from 2013-2018 were retrospectively reviewed to identify patients and obtain demographic, baseline, and short-term outcomes of maximal mouth opening (MMO), pain, and temporomandibular disability index (TDI). A total of 100 patients were included. Significant changes were noted in MMO, pain rating, and TDI from initial evaluation to discharge from physical therapy. Sex, age, and weight did not affect the outcomes. There was also no correlation between the number of visits attended and change in MMO. Patients treated conservatively did show improvements in short term outcomes (MMO, pain rating, and TDI). These changes were statistically significant, indicating that conservative therapy may be a beneficial treatment option for patients with TMJ dysfunction. Future studies assessing the long-term outcomes of TMJ patients treated conservatively would determine if this treatment is beneficial in the long-term. In addition, researching the effectiveness of specific interventions for TMJ patients, and if certain TMJ disorders are more responsive to conservative care than others would be valuable in providing information on the effectiveness of conservative treatment in this patient population.
