Evaluation of the efficacy of therapeutic ultrasound in the treatment of migraine.

Abstract

This study aims to evaluate the efficacy of therapeutic pulsed ultrasound (US) applied to the occipital nerve distribution area in chronic migraine patients. This prospective, randomized, double-blind, placebo-controlled, study was conducted on 58 patients diagnosed with migraine at the University of Health Sciences Bursa Yüksek Ihtisas Training and Research Hospital, Department of Physical Medicine and Rehabilitation between January 2018 and October 2018. The patients were randomly divided into two groups as sham and pulsed US group. Pulsed US was applied in Group 1 (n=29), and sham US was used in Group 2 (n=29) for 5 min for a total of 10 sessions in each group. The evaluation was made at pre-treatment, post-treatment first month (week six) and third month (week 14) using the numeric rating scale, and the Migraine Disability Assessment Scale (MIDAS). The final analysis was conducted with 52 patients (7 males, 45 females; mean age: 38.3±7.9 years; range, 20 to 65 years) due to drop-outs, with 27 patients in Group 1 and 25 patients in Group 2. A statistically significant improvement was found in all parameters at week six and week 14 compared to pre-treatment values in Group 1. A statistically significant worsening was detected in MIDAS 1, 4, 5, total questions, and a significant improvement was found in MIDAS A and B at week six compared to pre-treatment values in Group 2. A statistically significant worsening was found only in MIDAS total score at week 14 compared to pre-treatment values. In the comparison of the difference scores of the two groups, all parameters in Group 1 showed significant improvement at week six and week 14. The findings obtained in this study show that pulsed US applied to the occipital nerve distribution region in migraine patients can be effective on headache frequency, severity, and disability.
