Eficacia de una técnica de thrust para la disfunción glenohumeral en superioridad

Abstract

Objectives: To determine the efficacy of a thrust technique in immediately reducing pain intensity inactive abduction movement and in reducing painful sensitivity to pressure at the trigger points of themiddle deltoid muscle. Material and methods:A quasi-experimental pre-post intervention study was performed with two interventions in a single group of 20 volunteers of both sexes with upper shoulder dysfunction. Each patient acted as a member of the control group (non-intervention) and the test group (thrust technique). The test variables were analyzed statistically. Results: Student’s t-test, applied to the average pressure pain threshold at the middle deltoid triggerpoints before and after the thrust technique, revealed statistically significant differences (p < 0.05).The Kappa concordance between the three observers was 0.4669, indicating moderate concordance(0.41-0.60) among observers. Conclusions:The increase in the pain threshold to pressure at the trigger points in the middle deltoidmuscle indicates that the proposed thrust technique is effective in treating upward shoulder dysfunction.
