Difference of the width of ulnohumeral joint space between at rest and with flexor-pronator muscle contraction under gravity stress
| Elbow pain (n = 29) | No elbow pain (n = 60) | P value | |
|---|---|---|---|
| Difference between the width of ulnohumeral joint space at rest and the width of ulnohumeral joint space under gravity stress, mm | 0.8 ± 0.5 | 0.9 ± 0.6 | .81 |
| Difference between the width of ulnohumeral joint space at rest and the width of ulnohumeral joint with a maximal grip contraction with wrist ulnar flexion under gravity stress, mm | –0.1 ± 0.6 | 0.1 ± 0.6 | .4 |
| Difference between the width of ulnohumeral joint space at rest and the width of ulnohumeral joint with forearm pronation under gravity stress, mm | –0.2 ± 0.6 | 0.0 ± 0.8 | .11 |
Values are means ± standard deviations.
Significance: P < .05.
