About

For many years researchers have been documented that the shoulder of the throwing athlete acquires a increase in external rotation of the dominant limb compared to the contralateral side.This fact is followed with a loss of the internal rotation of the shoulder, which is related with a higher rate of injuries in this joint and it´s known as Glenohumeral Internal Rotation Deficit (GIRD). Among the approaches for this condition the literature is inconclusive due to the low methodological quality of clinical trials made,however, the manual therapy has been used with success to relief the pain and restore the range of motion. The purpose of this study is to analyse the effectiveness of a mobilization with movement technique to improve the internal rotation of the shoulder in throwing athletes with GIRD. It will be a randomized controlled trial with the CONSORT bases with 40 participants that will be divided into two groups: Control group that will be submitted for an evaluation of shoulder range of motion (internal/external rotation)of both limbs, upper limb active movements to warm-up (five minutes), posterior capsule stretching (Cross-body stretch for 3 sets of 30 seconds) and revaluation immediately post-intervention and four weeks post-intervention. Mobilization group that will be submitted for an evaluation of shoulder range of motion (internal/external rotation)of both limbs, upper limb active movements to warm-up(five minutes), posterior capsule stretching (Cross-body stretch for 3 sets of 30 seconds) plus a mobilization with movement technique to improve internal rotation of the dominant shoulder (three sets of 10 repetitions)and revaluation immediately post-intervention and four weeks post-intervention. To evaluate the range of movement it will be use a standard goniometer with an attached customizes bubble inclinometer to ensure proper perpendicular alignment of the goniometer to the ground. The investigators hypothesis is that both group will have improvements in the internal rotation of the dominant shoulder, however, the mobilization group will have a statistically significant difference compared to control group immediately post-intervention. Four weeks post-intervention this difference will equalize, because of the only intervention applied. Results will be expressed as hazard ratios (HR) with their respective confidence intervals at 95% and adopting α = 0.05. All analyzes will be performed by SPSS version 17.0
