Kinesiotherapy associated with laser GaAs application in shoulder-rotator cuff syndrome

Abstract

We verified the effects of kinesiotherapy associated with the application of a gallium arsenate AsGa laser (904 nm) to pain, joint amplitude, and hidroxiproline excretion (HP) in subjects with shoulder rotator cuff syndrome (SRCS). Sixty-nine heterogeneous individuals of both sexes from Vicosa, MG, aged between 40 and 65, diagnosed with shoulder rotator cuff syndrome and referred to physiotherapy participated voluntarily in this study. Pain was measured on the Borg CR10 scale; HP was analyzed by the colorimetric protocol and joint amplitude by the goniometric LABIFIE protocol. Descriptive statistics were used, with the mean values and standard deviation and a probability interval of 95% minimum and maximum of the mean. In the inferential, 2 × 2 ANOVA for repeated measures was used to evaluate the HP and joint amplitude, followed by the Tukey post hoc test to identify the significant differences. For evaluating pain, the Friedman test was used and followed by the Wilcoxon test to identify the significant differences. The significance level adopted for all the tests was 0.05, and all the tests were performed by the software Premir by Biostatistics, version 4.0. The results showed that there was a significant improvement in the pain variables, hidroxiproline, and in the joint amplitudes of the flexion, horizontal flexion, abduction, shoulder medial rotation, lateral rotation, and horizontal rotation movements in the group submitted to kinesiotherapy associated with an AsGa laser.
