Comparison of the effect of two methods of ischemic compression of trigger points on the change of pain threshold and electromyographic parameters of the trapezius muscle.

Aim: The aim of the study was to compare the effect of ischemic compression of trigger points, in which pressure was maintained in a pulsating (group A) and constant (group B) manner on the pain threshold and EMG parameters of the trapezius muscle. Material and methods: 28 students with a latent trigger point in the described muscle participate in use. Compression pain threshold measured using a hand dynamometer, muscle biopotential values at rest, and motor activity determined using EMG. Both parameters were evaluated before and after the therapy. Results: in each of the examined groups a statistically significant decrease in the pain threshold was observed, additionally in group B there was a significant decrease in the muscle resting tone. The analysis of other parameters did not show any significant changes. Conclusions: according to the authors, ischemic compression is characterized by greater clinical usefulness in the treatment of pain and increased muscle tone.
