Assessment of Upper Trapezium Pain and Muscle Strength After Posiconal Release and Myofascial Release

Abstract

Myofascial Pain Syndrome is characterized by sensory, motor, and autonomic symptoms caused by myofascial trigger points (TPs), resulting in quality of life, daily and social activities. The objective is to compare the levels of strength and pain tolerance before and after the use of Positional Release (TLP) and Myofascial Release (TLM) techniques. This is carried out as cross-sectional, quantitative, experimental study. Individuals with myofascial trigger points in the upper trapezius participated in the study and were randomly divided into three intervention groups (A, B, and C), where A corresponds to TLP, B corresponds to TLM, and C corresponds to the placebo group. Strength and pain tolerance levels were measured using a handheld isometric dynamometer and an algometer. The average of three pre- and post-intervention measurements was used as the reference value for the results. Groups A and B showed improvement in pain tolerance, compared to Group C, where pain tolerance worsened. As for the gain in strength, it cannot be said that there were significant changes, the three groups showed a slight increase in strength. The presented resources are easy to apply and low cost and prove to be auxiliary tools in the treatment of patients with neck pain.
