Abstract
Background
Interventions addressing pain and impaired functionality in individuals with temporomandibular disorders (TMDs) are needed.
Objective
To compare the effects of 4 weeks of exercise combined with ischaemic compression and exercise alone in patients with TMDs.
Methods
Fifty patients who were diagnosed with TMDs were randomised into Group 1 (exercise combined with ischaemic compression technique) (n = 25) or Group 2 (exercise alone) (n = 25). Both groups performed 4 weeks of Rocabado's exercise and 3 weeks of postural exercise, while Group 1 received ischaemic compression to the masseter muscle for a total of 3 sessions in addition to exercise. A ruler was used to assess range of motion (ROM) (painless mouth opening (PMO), maximum mouth opening, maximum assisted mouth opening (MAMO), left lateral movement and right lateral movement), the visual analogue scale and graded chronic pain scale were used to assess pain, an algometer was used to determine the pain pressure threshold (PPT), and the 8‐item jaw functional limitation scale was used to assess, functionality. The assessments were performed at baseline, at week 1 and at week 4.
Results
The participants in Group 1 exhibited larger PMO (F = 5.26, P = .02) and MAMO values (F = 6.71, P = .01) than did the patients in Group 2 at week 1. The effect size was small for MAMO (ES = 0.27) and moderate for PMO (ES = 0.51). However, there were no significant differences in any other outcomes between groups at week 1 or 4.
Conclusion
In summary, this randomised controlled trial indicates that exercise combined with ICT and exercise alone have similar effects on ROM, pain, the PPT and functionality in patients with TMDs.
