Outcome of therapy in the conservative management of temporomandibular pain dysfunction disorder

Abstract

summary The present study considered predictors of the outcome of treatment for temporomandibular pain dysfunction disorder (TMPD). Thirty‐seven patients were assessed with objective and self‐report measures of physiological and psychosocial aspects of this disorder at initial assessment and at 6‐month follow‐up subsequent to conservative physical therapy. Patients were subdivided into slow and rapid responders to conservative physical therapy based on self‐reported level of improvement. Measures employed included the Temporomandibular Pain Dysfunction Disorder Questionnaire and the Temporomandibular Pain Dysfunction Disorder Clinical Form. Eighty‐one per cent of patients showed a 50% or greater improvement in pain severity at follow‐up, with minimal differential changes across the two groups found in the physiological symptoms, while the rapid responding group showed greater improvement in terms of psychosocial factors. These findings indicated that psychosocial factors, particularly coping strategies and illness behaviour, cannot be ignored in the management of TMPD.
