Effect of the intervention between the intervention and control group, measured by prevalence ratio (PR; n=109)
| Outcome variable | PR (95% CI)*† |
|---|---|
| Regional pain | |
| Dominant proximal UE | 0.9 (0.7 to 1.2) |
| Non-dominant proximal UE | 1.0 (0.8 to 1.4) |
| Dominant distal UE | 0.8 (0.5 to 1.3) |
| Non-dominant distal UE | 1.2 (0.6 to 2.2) |
| RULA non-neutral posture | |
| Dominant UE | 0.9 (0.9 to 1.0) |
| Non-dominant UE | 0.9 (0.8 to 0.9) |
| Spine and lower extremities | 0.8 (0.5 to 1.2) |
| Full dominant RULA | 0.9 (0.9 to 1.0) |
| Full non-dominant RULA | 0.8 (0.8 to 0.9) |
| Hand activity level (HAL) score | |
| Dominant UE | 0.9 (0.8 to 1.0) |
| Non-dominant UE | 1.4 (1.2 to 1.6) |
*PR: how large the prevalence of the health or exposure outcome is in the intervention group relative to the control group.
†PR model: dichotomous dependent variable (regional pain, RULA or HAL) and intervention (no/yes) as the explanatory variable of interest.
RULA, rapid upper limb assessment; UE, upper extremity.
