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

Primary | Analyse the effectiveness of a mobilization with movement technique to improve internal rotation of the shoulder in throwers athletes with GIRD | The 40 patients will be divided in two groups of 20. Both will perform a evaluation of the internal and external rotation of the shoulders to determine the individual internal rotation deficit of the dominant shoulder compared to the contralateral side. One group (Control) will perform what the literature recommends (Stretch of the posterior capsule), and the other group (Mobilization) will add to the control intervention a mobilization with movement technique to improve the internal rotation deficit which was identified previously. | Immediately post-intervention and four weeks post-intervention | Yes |
