Comparison of pain level and range of motion of shoulder joint between surgical and nonsurgical sides.
| | Surgical side (n=20) | Nonsurgical side (n=14) | P |
| VAS, (median, IQR) | 4(1-5) | 0(0-0) | 0.001 | Range of Motion, degree (median, IQR) | | | | Flexion | 147.5(135-158.75) | 180(180-180) | 0.001 | Extension | 55 (50-60) | 60(50-60) | 0.112 | Abduction | 140 (71.25-160) | 180(180-180) | 0.001 | Adduction | 55 (45-60) | 60(45-60) | 0.569 | Internal rotation | 70 (60-70) | 70(60-71.25) | 0.931 | External rotation | 87.5(71.25-90) | 90(77.5-90) | 0.396 |
