[Purpose] This study investigated the effectiveness of a short-term exercise program
combining range-of-motion exercise for the temporomandibular joint and self-traction
therapy in patients with temporomandibular joint disc displacement without reduction.
[Subjects and Methods] The study participants comprised 36 females with jaw trismus and
moderate to severe functional pain. The range-of-motion exercise for the temporomandibular
joint was performed at the first visit by the therapist, and the patients were instructed
to perform self-traction therapy in the morning and during daily bathing until the next
visit 2 weeks later. Maximum mouth opening distance and the visual analogue scale score
were used to compare pain on motion and mastication as well as the impact of the program
on daily activities at the first consultation and 2 weeks later. [Results] All symptoms
were significantly improved after 2 weeks of treatment. [Conclusion] A program that
combines exercise for the temporomandibular joint and self-traction therapy can improve
range of motion at the joint in the short term and reduce pain and difficulty associated
with daily activity in patients with temporomandibular joint disc displacement without
reduction. The results of this study suggest that such a program can serve as an effective
conservative treatment.
