Rotator cuff tears are common musculoskeletal injuries that can lead to altered scapular and rotator cuff muscle activation patterns and reduced function. This study aims to investigate the relationship between rotator cuff tear severity and scapular and rotator cuff muscle activation patterns.

The primary objective of this study is to determine whether a relationship exists between the severity of rotator cuff tears and the activation patterns of scapular and rotator cuff muscles. Secondary objectives include:

1. Identifying differences in muscle activation patterns between varying tear sizes.
2. Evaluating the potential of these activation patterns as an indicator for the severity of rotator cuff tears.
3. Assessing the influence of muscle activation patterns on the functional capacity of the affected shoulder.
