| ROM | Preoperative group | Group range (degrees) | Mean improvement (degrees) | MCID55 | SCB54 | Group mean, absolute (degrees) | Group size (n/%) |
|---|---|---|---|---|---|---|---|
| External rotation | High | 41-60 | 13.3 | 14.5 | 20.1 | 60.0 | 6/15.4 |
| Medium | 21-40 | 15.4 | 14.5 | 20.1 | 47.5 | 12/30.8 | |
| Low | 0-20 | 42.5 | 14.5 | 20.1 | 50.0 | 21/53.8 | |
| Forward elevation | High | >140 | 3.9 | 23.1 | 45.5 | 161 | 9/23.1 |
| Medium | 101-140 | 40.0 | 23.1 | 45.5 | 161 | 7/17.9 | |
| Low | 60-100 | 68.3 | 23.1 | 45.5 | 151 | 23/59.0 |
ROM, range of motion; MCID, minimal clinically important difference; SCB, substantial clinical benefit.
In bold, greatest improvement in patients with highest preoperative limitations.
