X-axis angular rotation | Pearson’s correlation coefficient | Scapulothoracic upward rotation | Glenohumeral abduction | Elbow valgus |
|---|---|---|---|---|
Scapulothoracic upward rotation | ρ (P value) | − 0.545 (< 0.001*) | − 0.116 (0.146) | |
Glenohumeral abduction | ρ (P value) | − 0.545 (< 0.001*) | 0.017 (0.892) | |
Elbow valgus | ρ (P value) | − 0.116 (0.146) | 0.017 (0.892) |
