Study aim
-
Appropriate training protocol to correct scapular movement disorder and prevent shoulder injuries in volleyball players
-
Design
-
This study is a clinical trial with a control group, with parallel groups, one-way blind, randomized on 48 players with scapular movement disorder. Excel random function was used for randomization.
-
Settings and conduct
-
. Anthropometric variables, range of motion of internal and external rotation of the shoulder, and strength of internal and external rotational muscles of the shoulder will be evaluated. Then, the subjects will be divided into two groups of training and control. Based on the studies, the training group will participate in selected exercises for eight weeks for three sessions per week, and after completing the training period, they will re-evaluate the studied variables. Took. The evaluator is not aware of the classification of individuals.

Participants/Inclusion and exclusion criteria
-
Inclusion criteria : female gender, having at least three years of experience in regular volleyball and having a scapular movement disorder.
Exclusion conditions: Pain in the shoulder girdle and neck in any of the normal and training conditions, history of fracture or dislocation in any of the bones of the shoulder girdle, complete rupture of the shoulder girdle muscles
-
Intervention groups
-
The training protocol consists of three stages, the first part focusing on shoulder control and increasing range of motion, the second phase on increasing scapular muscle strength and sensory-motor exercises, and the third phase on advanced sensorimotor exercises. All exercises are done in three sets with 15 repetitions. The rest between each set is gradually reduced until the end of the period.
The control group has their own daily exercise program.

Main outcome variables
