Table 4 Bland–Altman analysis of difference between radiographic and EMS measurements
From: Accuracy and reliability of tridimensional electromagnetic sensor system for elbow ROM measurement
Range of motion | Mean ± SD of difference (°) | Upper 95% CI limit (mean + 1.96SD) | Lower 95% CI limit (mean − 1.96SD) | Absolute maximal error (± 1.96SD) |
|---|---|---|---|---|
Extension | 2.0 ± 2.8 | 7.6 | − 3.5 |  ± 5.5 |
Flexion | 1.0 ± 11.2 | 22.9 | − 20.9 |  ± 21.9 |
