Table 2.
Clinical severity criteria by physical examination in the groups with early and late recovery of the pre-injury level of performance (≤40 days vs >40 days, respectively). The data are the numbers of patients (%).
| Early recovery n=65 | Late recovery n=55 | |
|---|---|---|
| Worst VAS pain score >6 (n=69) | 23 (19.2%) | 46 (38.3%)* |
| Pain of any severity for >3 days during every day activities (n=48) | 16 (13.3%) | 32 (26.7%)* |
| Popping sound at injury (n=30) | 8 (6.7%) | 22 (18.3%)* |
| Bruising (n=18) | 5 (4.2%) | 13 (10.8%)* |
| Tenderness upon palpation (n=89) | 48 (40%) | 41 (34.2%) |
| Pain upon isometric contraction (n=80) | 45 (37.5%) | 35 (29.2%) |
| Pain upon passive limb straightening (n=102) | 52 (43.3%) | 50 (41.7%) |
| Limitation >15° to uninjured limb (n=54) | 19 (15.8%) | 35 (29.2%)* |
