Demographic and Clinical Characteristics of Rotator Cuff Tear Study Participants

A study of 20 participants assessed the response of shoulder muscles to low-intensity exercise in individuals with and without rotator cuff tears. The dataset includes pre- and post-exercise ultrasound measurements of shear wave speed, cross-sectional area, and strength for the supraspinatus and infraspinatus muscles. It was authored by Andrew J. Nasr and last updated on 2026-05-27.

Use Cases

• Compare muscle stiffness changes based on shear wave speed measurements between symptomatic and asymptomatic groups.
• Analyze the relationship between muscle cross-sectional area and exercise under active versus passive conditions.
• Investigate the correlation between peripheral weakness, indicated by strength decline, and the presence of rotator cuff tears.
• Model differential muscle adaptation to low-intensity rehabilitation protocols based on tear status.

Strengths

• Includes data from a controlled study with 20 participants.
• Contains specific physiological measurements like shear wave speed and cross-sectional area.
• Provides statistically significant p-values for key findings, such as p=0.0021 for passive supraspinatus shear wave speed reduction.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 9.5 KB, indicating limited scope.
