Effect of ischemic pressure using a Backnobber II device on discomfort associated with myofascial trigger points

J Bodyw Mov Ther. 2011 Jul;15(3):319-25. doi: 10.1016/j.jbmt.2010.06.007. Epub 2010 Jul 22.


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.
