Effectiveness of a Home Exercise Program in Combination with Ultrasound Therapy for Temporomandibular Joint Disorders

抄録

[Purpose] This study compared the effectiveness of home exercise alone versus home exercise combined with ultrasound for patients with temporomandibular joint disorders. [Subjects and Methods] This study enrolled 23 female and 15 male patients who were divided randomly into two groups. The home exercise group performed a home exercise program consisting of an exercise program and patient education, and the home exercise combined with ultrasound group received ultrasound therapy in addition to the home exercise program. Pain intensity was evaluated using a visual analogue scale. Pain free maximum mouth opening was evaluated at baseline and 2 weeks after the treatment. [Results] There was no difference between the two groups in baseline values. After the treatment, the visual analogue scale decreased and pain free maximum mouth opening scores improved significantly in each group. Additionally, both values were higher in the home exercise combined with ultrasound group than in the home exercise group. [Conclusion] The combination of home exercise combined with ultrasound appears to be more effective at providing pain relief and increasing mouth opening than does home exercise alone for patients with temporomandibular joint disorders.
