Introduction: The most critical clinical presentation in myofascial pain syndrome is trigger points. Trigger points are the main problem in 30% of the patients presenting to general internal medicine practice. One of the treatments used for trigger points is ultrasound therapy. The high- power pain threshold ultrasound (HPPTUS) technique is one of the therapeutic ultrasound modifications used to treat trigger points. The present randomized clinical trial aimed to investigate the immediate effect of high-power pain threshold ultrasound on treating active trigger points of the upper trapezius muscle in men with mechanical neck pain. Materials and Methods: Fourteen men with mechanical neck pain (Mean±SD age: 34.50±5.24 years) who met the inclusion and exclusion criteria participated in this study. The visual analog scale (VAS), pressure pain threshold (PPT), and range of motion of cervical lateral flexion (CLF) were assessed before and after the treatment. The ultrasound probe was placed on the trigger point. The frequency was set to 1 MHz, and the intensity increased from 0.5 to 2 until the patient reported an unpleasant sensation. The probe was held there for 4 seconds. Then, the intensity was reduced by 50%, and the probe was moved over and around the trigger point. This process was done several times for three minutes. Results: Analysis of pre-treatment and post-treatment findings showed that the VAS (P<0.001), PPT (P=0.001), and CLF (P<0.001) improved significantly after applying the HPPTUS to trigger points. Conclusion: Ultrasound significantly improved the muscular symptoms of the trigger points.

Introduction: Musculoskeletal disorders are among the main causes of disability in modern life. Myofascial trigger points are very common among musculoskeletal disorders and may occur through ordinary common activities. This study aimed to determine the combined effects of laser therapy and Ischemic Compression (IC) on the treatment of Myofascial Trigger Points (MTrPs) at the upper trapezius muscle. Materials and Methods: Twenty men with at least one active trigger point at their upper trapezius muscle voluntarily participated in this study. Trigger  points  were under treatment of laser irradiation (6 Joules per point) and also ischemic compression. Treatment approaches were applied over the pain point every other day for 5 sessions in 10 days. Neck disability index, pain intensity by visual analog scale, pressure pain threshold by algometry, and cervical lateral flexion by goniometer were assessed and recorded before the intervention, and immediately after the last session. Results: At the end of treatment, statistically significant improvements were seen in the neck disability index, VAS value, pressure pain threshold, and cervical lateral flexion. VAS values of the treatment and control groups were compared with the baseline (P<0.001). Conclusion: Application of combined laser and compression therapy was effective on the pain and level of disability of patients with trigger points in the upper trapezius muscle.
