Objective:
This study investigated and compared the efficacy of dextrose phonophoresis and Pulsed Electromagnetic Field (PEMF) on pain, range of motion (ROM) and function in patients with Temporomandibular Dysfunction (TMD).
Methods:
45 patients with TMD aging from 25 to 45 years, with mean age 29 ± 2.5 years were included in this study, they were assigned randomly into 3 equal groups each contain fifteen TMJ dysfunction patients. Group (A) in which each patient received 50% dextrose phonophoresis for 5 min and therapeutic ultrasound for 5 min, Group (B) in which each patient received Pulsed Electromagnetic Field (PEMF) with frequency of 50 HZ for 50 min, and traditional physiotherapy ultrasound for 5 min, while in the control group (C) the patients received traditional physiotherapy ultrasound for 5 min only, the frequency of treatment session in the three groups was 3 days per week for 4 weeks. The assessment tools were visual analog scale (VAS) for pain evaluation, plastic ruler for TMJ ROM measurements while Fonseca's questionnaire was used for evaluation of TM function at baseline and 4 weeks later.
Results:
Paired t-test for comparison between pre and post treatment measurements in each group showed significant decrease pain as well as improvement of ROM and Fonseca's questionnaire in group A and B than placebo group.
Conclusions:
The results found that both dextrose phonophoresis and PEMF have beneficial effects considering pain, ROM and function in patients with (TMD).
