Objective: The purpose of this study was to assess the effectiveness of ischemic pressure on myofascial trigger point (MTrP) sensitivity.
Design: Randomized, controlled study with the researcher assessing MTrP sensitivity blinded to the intervention.
Participants: Twenty-eight people with two MTrPs in the upper back musculature.
Intervention: The sensitivity of two MTrPs in the upper back was assessed with a JTECH algometer. One of the two MTrPs was randomly selected for treatment with a Backnobber II, while the other served as a control.
Outcome measures: Pre- and post-test pressure-pain thresholds of the MTrPs
Results: There was a significant difference between the pre- and post-test sensitivities of the treated and non-treated MTrPs (p=0.04).
Conclusions: The results of this study confirm that the protocol of six repetitions of 30-s ischemic compression with the Backnobber II rendered every other day for a week was effective in reducing MTrP irritability.
