About

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.
