Investigating muscle activation patterns in rotator cuff tears
The Relationship Between Rotator Cuff Tear Severity and Scapular and Rotator Cuff Muscle Activation Patterns: A Cross-Sectional Study
This study is trying to see how different sizes of rotator cuff tears affect muscle activity in the shoulder and how that relates to how well people can use their shoulder.

What this trial studies
This observational study aims to explore the relationship between the severity of rotator cuff tears and the activation patterns of scapular and rotator cuff muscles. By utilizing surface electromyography (sEMG) assessments, the study will identify differences in muscle activation based on varying tear sizes and evaluate these patterns as potential indicators of tear severity. Additionally, the study will assess how these activation patterns influence the functional capacity of the affected shoulder. Participants will include individuals aged 18 to 60 with confirmed rotator cuff tears.
Who should consider this trial
Good fit: Ideal candidates are individuals aged 18 to 60 with a diagnosed rotator cuff tear confirmed by MRI.
Not a fit: Patients with a history of shoulder surgery or unrelated shoulder disorders may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance the understanding of rotator cuff injuries and lead to improved assessment and treatment strategies for patients.
How similar studies have performed: While similar studies have explored muscle activation patterns in shoulder injuries, this specific approach focusing on rotator cuff tear severity is relatively novel.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: * Age between 18 and 60 years. * Diagnosis of rotator cuff tear confirmed by a qualified orthopedic surgeon. * MRI scan showing the size of the tear (small, medium, large, or massive). * Ability to provide informed consent and comply with the study protocol. Exclusion Criteria: * History of shoulder surgery or other shoulder disorders unrelated to rotator cuff tears. * Presence of neurological, cardiovascular, or respiratory disorders that could influence muscle activation patterns. * Contraindications for sEMG assessment, such as skin allergies or infections. * Inability to perform the required functional tasks due to severe pain or disability.
