Background and purpose. This study was intended to assess the efficacy of physical therapy treatment on patients with various temporomandibular disorders at 6, 12, 18, and 24 months after their discharge from physical therapy. These patients were all treated at Therapeutic Associates - Cedar Hills Physical Therapy in Portland, Oregon. Methods. Objective measures (Therapeutic Associates Outcomes System Functional Index (TAOS), subjective pain rating with a Visual Analog Scale (VAS), and perceived improvement rating with a VAS) were acquired from the patient's status at discharge and were also mailed to each patient during the appropriate month and returned to us within two weeks. A two-way ANOVA with repeated measures was used for the statistical analysis of the acquired data. Results. The statistical analysis demonstrated no significant difference when comparing between groups, over time, or between the two independent variables. This was true for functional index scores, pain and improvement measurements. Conclusion and Discussion. These results show that the treatments provided by Therapeutic Associates - Cedar Hills Physical Therapy have maintained function, pain, and improvement levels for these patients over a 6 month to 24 month period post-discharge.
