Summary

The study consisted of 60 women who had pain-point pains in the upper fibers of the trapezius muscle. They had a medical age of 22.8 years, with a body mass index of 22.8 kg / cm2.They underwent an initial assessment, with a visual analogue pain scale, followed by an assessment of pain threshold, and manual muscle strength.Then, they were allocated into three groups: control group with 20 volunteers without intervention, placebo group with 20 volunteers with shock wave simulation and an intervention group with 20 volunteers with shock wave therapy. All volunteers were evaluated immediately after the protocol (post evaluation) and 48 hours after the intervention protocol (48 hour evaluation). A mixed ANOVA of repeated measurements was used for intra and intergroup comparisons, followed by tukey post hoc. Significance was set at 5% (p \<0.05).

Detailed description

The objective was to investigate the effects of shock wave therapy on the pain of trigger points in the upper fibers of the trapezius muscle. A randomized, blinded clinical trial of 60 women (mean age 22.8 years and mean body mass index of 22.8 kg / cm2) with presence of trigger points in the upper fibers of the trapezius muscle. These were submitted to an initial evaluation (AV1), composed of the visual analogical pain scale, followed by an evaluation of the pain threshold, using algometry. Then, the evaluation of the electromyographic activity of the upper trapezius muscle was performed, as well as of its muscular strength by manual dynamometry. Then allocated randomly in 3 groups: Control (n = 20), without intervention; Placebo (n = 20), simulation of the application of shock wave therapy; And shock wave therapy (n = 20). Shock wave therapy was performed with the Master Plus 200® Storz Medical equipment, radial emission 2000 pulses, 15 Hz frequency and pressure of 1 Bar. All volunteers were evaluated immediately after the protocol (post evaluation) and 48 hours After the intervention protocol (evaluation 48 hours). A mixed ANOVA of repeated measurements was used for intra and intergroup comparisons, followed by tukey post hoc. Significance was set at 5% (p \<0.05).
