Abstract
The objective of this study was to determine the effect of enhancing conventional care for people with chronic painful temporomandibular disorders (TMD) with an individualised contemporary pain science education (PSE) intervention. In this randomized controlled trial, a consecutive sample of 148 participants (18-55 years of age) was randomized into 2 groups: PSE-enhanced conventional care or Conventional care alone. Conventional care involved a 6-week, 12-session manual therapy and exercise program. The PSE enhancement involved 2 sessions of modern PSE, undertaken in the first 2 treatment sessions. Primary outcomes were pain intensity, assessed with a numeric pain rating scale, and disability, assessed with the craniofacial pain and disability inventory, post-treatment. Linear mixed model analyses were used to investigate between-group differences over time. There was a statistically and clinically meaningful effect of PSE enhancement on disability (Mean Difference = 6.1, 95% CI: 3.3-8.8), but not on pain intensity, post-treatment. Secondary analyses suggested clinically meaningful benefit of PSE enhancement on pain and disability ratings at 10-week and 18-week follow-ups, raising the possibility that preceding conventional care with a PSE intervention may result in long-term benefits. PERSPECTIVE: The addition of modern Pain Science Education (PSE) intervention improved disability for people with chronic TMD receiving manual therapy and exercise, but not pain. A mean difference in pain and disability favoring the PSE group at the 10- and 18-week follow-ups, respectively, suggests that PSE addition resulted in longer-lasting effects.
