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

Summary

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.

Conditions

• Trigger Point Pain, Myofascial

Interventions

OTHER

high power pain threshold ultrasound which the dose was kept constant

Participants in HPPT-US 1 group received the HPPT-US treatment. The intensity was gradually increased from 0.5 W/cm² to the pain threshold level at which the patient verbally reported the pain. The therapist kept the intensity at that level for 5 s, and then moved the US transducer in a circle without the change of the intensity for 15 s. The procedure was repeated 3 times. The patients were asked whether serious pain or any abnormal sensation was felt during HPPT-US. The intensity was varied from 0.5 to 1.2 W/ cm².

OTHER

high power pain threshold ultrasound which the dose reduced to one half

Participants in HPPT-US 2 group also received the HPPT-US treatment. The intensity was gradually increased from 0.5 W/cm² to the pain threshold level at which the patient verbally reported the pain. The therapist kept the intensity at that level for 5 s, then reduced the dose half and moved the US transducer in a circle for 15 s. The procedure was repeated 3 times. The patients were asked whether serious pain or any abnormal sensation was felt during HPPT-US. The intensity was varied from 0.5 to 1.2 W/ cm².

OTHER

ischemic compression

Participants in IC group received ischemic compression therapy. The technique was applied in the sitting position to participants. Ischemic compression was performed by compressing trigger points identified by palpation with tolerable intensity using thumb. The duration for each trigger points was 1 minute. Then the muscle containing the trigger point was applied intramuscular stretching for 30 seconds by therapist
