Comparison of High Power Pain Threshold Ultrasound and Ischemic Compression Techniques for Treatment of Trigger Points

Comparison of High Power Pain Threshold Ultrasound and Ischemic Compression Techniques for the Treatment of Latent Myofascial Trigger Points: A Randomized Controlled Study

This study aimed to compare the efficacy of ischemic compression and two different application methods of high power pain threshold ultrasound techniques on latent trigger point treatment. Asymptomatic subjects divided into three groups. First group took high power pain threshold ultrasound in which the intensity is kept constant at the pain level; second group took high power pain threshold ultrasound which the intensity is kept constant at half the pain level and third group took ischemic compression. All participants were asked to complete the questionnaires, which assessed pain, psychological factors and disability before treatment, after 1 week and 1 month follow-up. After each participants completed the questionnaire, the physical therapist evaluated the MTrPs. MTrPs assessment was performed before treatment, immediately after treatment, after 1 week and 1 month follow-up.

Myofascial trigger points have been defined as discrete and hyperirritable areas located within a taut band of skeletal muscle or fascia which when compressed produce pain, tenderness, dysfunction and autonomic phenomena. The treatment techniques aimed to return the fiber groups affected by myofascial trigger points to their normal length and endplates to their normal function. Although both ischemic compression and two different application methods of high power pain threshold ultrasound techniques are effective methods in the treatment of trigger points , there are no studies showing which technique is more effective. It is aimed to to compare the efficacy of ischemic compression and two different application methods of high power pain threshold ultrasound techniques on myofascial trigger point treatment.
