Brief Summary

Introduction: Handball is a sport with a high prevalence of shoulder injuries due to the overuse that causes a glenohumeral internal rotation deficit, and excess of external rotation and scapular dyskinesia. Stretching is essential to restore physiological movement and improve strength. Aim: To evaluate the efficacy of a posterior capsule stretching and strengthening of the shoulder and scapular program in handball players from 18 to 37 years old. Study design: randomized clinical trial, multicenter, single-blind with follow-up period. Methods: 60 handball players will be randomly assigned to the two study groups (experimental and control). The intervention will last 4 weeks, with 3 weekly sessions with a duration of 21 and 12 minutes each. The study variables will be: range of motion in internal and external rotation (goniometer), throwing speed (Ball Throwing Speed Test), functionality (DASH questionnaire), perceived exertion (Borg scale), glenohumeral stability (CKCUEST y YBT-UQ Test) and the throwing force (Overhead Medicine Ball Throw). The intervention will consist in the application of stretching of the posterior shoulder capsule with an exercise protocol. A Kolmogorov-Smirnov analysis will calculate the normality of the distribution. In case of homogeneity of the groups, with the t-student test of repeated measurements and an ANOVA of repeated averages, the difference between the different evaluations and the intra- and inter-subject effect will be calculated. Expected results: Improved range of motion of the shoulder, strength and throwing speed after the intervention.

Outcome Measures

Primary Outcomes (1)

• Change from baseline functionality of the shoulder after treatment and at month

  The functionality of the shoulder will be measured with the questionnaire Disability of the Arm, Shoulder and Hand (DASH). This scale consists of 30 items (of functionality). The score range of this scale ranges from 0 to 100 points (where a higher score indicates less functionality).

  Screening visit, within the first seven days after treatment and after one month follow-up visit

Secondary Outcomes (6)

• Change from baseline perception of effort after treatment and at month

  Screening visit, within the first seven days after treatment and after one month follow-up visit

• Change from baseline launch speed after treatment and at month

  Screening visit, within the first seven days after treatment and after one month follow-up visit

• Change from baseline shoulder stability after treatment and at month

  Screening visit, within the first seven days after treatment and after one month follow-up visit

• Change from baseline distance range after treatment and at month

  Screening visit, within the first seven days after treatment and after one month follow-up visit

• Change from baseline strength of upper limbs after treatment and at month

  Screening visit, within the first seven days after treatment and after one month follow-up visit

Study Arms (2)

Experimental

EXPERIMENTAL

The subjects that are part of the experimental group will carry out the intervention thought the performance of strengthening exercises of the shoulder and scapula, and capsular stretches.

Other: Experimental

Control

ACTIVE COMPARATOR

Subjects that are part of the control group will perform shoulder strengthening exercises exclusively.

Other: Control

Interventions

Experimental OTHER

Two exercises will be done to strengthen the external rotation (using elastic bands): standing with 90 degrees of shoulder abduction and elbow flexion and also in standing with the shoulder in neutral position and the elbow flexed to 90 degrees. Subjects will perform 3 sets of 10 repetitions with the band slightly stretched, at a distance of 0.70 m from the wall. Dumbbell exercises will be performed through 4 exercises: flexion in the horizontal plane of 135º, external rotation in lateral decubitus, horizontal abduction with external rotation, and extension in prone position. There will be 5 repetitions each exercise of 3 seconds each, with 2 minutes of rest between exercises.

Also known as: Strengthening exercises and capsular stretches

Experimental

Control OTHER

Two exercises will be done to strengthen the external rotation, using elastic bands. The first, standing, with 90 degrees of shoulder abduction and elbow flexion. The second, also in standing, with the shoulder in neutral position and the elbow flexed to 90 degrees. Subjects will perform 3 sets of 10 repetitions with the band slightly stretched, at a distance of 0.70 m from the wall. The band will be subject to a surface, at an equal distance from the subject's elbow to the ground. The repetitions will last one second in concentric external rotation and two seconds in eccentric external rotation, with a rest of 30 seconds between series.
