Photobiostimulation in patients with shoulder impact syndrome. Randomized clinical trial

ABSTRACT

BACKGROUND AND OBJECTIVES:

To evaluate the effects of cluster therapy (Laser+LED) on shoulder impact syndrome, aiming at modulating pain and functionality.

METHODS:

Clinical, randomized, non double-blind study. Consisting of 28 individuals of both sexes, aged between 18 and 50 years, who were separated into: control group (CG n=13) and treatment group (TG n=15). The volunteers answered the Shoulder Pain and Disability Index (SPADI) questionnaire and goniometric evaluation of three active movements: flexion, abduction, and external rotation. The treatment group was submitted to Fluence Cluster - HTM, with energy of 12.8J, for 1 min and 30 seconds, 3 times a week, for 4 weeks, totaling 12 therapies, in the insertion of the tendon of the supraspinatus muscle and the passage of the long portion of the biceps brachii. The control group received orientation regarding daily activities.

RESULTS:

In both groups there was a reduction in pain, but the effect size observed was greater for the treatment group In the total SPADI evaluation, treatment presented a significant reduction in values, again with a greater effect size. In active movements, both flexion and external rotation, again the group that used the cluster had advantages, both inferential and in effect sizes.

CONCLUSION:

The cluster significantly reduced pain and increased functionality in patients with shoulder impingement syndrome.
