Logistic regression analysis of factors related to high signal intensity change in joint capsule.
| Factor | Odds ratio (95% conf. interval) | p-value |
|---|---|---|
| Age | 1.01 (0.98–1.05) | 0.45 |
| Gender | 1.62 (0.80–3.28) | 0.18 |
| Night pain | 5.98 (2.95–12.15) | <0.01 |
| ROM: FF | 0.99 (0.97–1.02) | 0.51 |
| ROM: ER1 | 1.00 (0.97–1.04) | 0.88 |
| ROM: ER2 | 0.99 (0.95–1.02) | 0.44 |
| ROM: IR | 0.69 (0.45–1.04) | 0.08 |
| No teara | ||
| PTT | 1.20 (0.57–2.55) | 0.63 |
| FTT | 1.77 (0.63–4.92) | 0.28 |
FF:forward flexion, ER1:external rotation with arm at side, ER2:external rotation with arm at 90° abduction, IR:internal rotation.
ROM of IR indicated 4 levels, 1: the buttocks, 2: 5th to 3rd lumbar spine, 3: 3rd to 1st lumbar spine, 4: thoracic spine and above.
PTT = partial thickness rotator cuff tear, FTT = full thickness rotator cuff tear.

No tear was used as a comparison with other rotator cuff injuries (PTT and FTT).
