Summary data and statistical outcomes for glenohumeral joint total range of motion (TROM) and glenohumeral joint total ROM difference (TROMD) for all age groups. These data are presented in degrees of rotation
| Age groups (n) | Mean ± SD total ROM | Differences between means: D vs ND | Difference in total ROM (TROMD) | |
|---|---|---|---|---|
| Dominant side Non-dominant side (95% CI) | Non-dominant side (95% CI) |
Tdf-ratio (p-value) Effect size (ES = d) |
