Relationships between the Observer Startle Magnitude score and the Kinect, Kinematic, Load Platform and KLT estimates of startle magnitude.
| Measure | n | Corr. Coef. (p-value) | Coefficient estimate (with SE) | Wald Χ2 (p-value) |
|---|---|---|---|---|
| Kinect Acceleration | 280 | 0.529 (<0.001) | −0.395 (0.047) | 70.126 (<0.001) |
| Kinect Speed | 280 | 0.606 (<0.001) | −0.243 (0.028) | 75.447 (<0.001) |
| Kinematic Acceleration | 70 | 0.743 (<0.001) | −1.013 (0.166) | 37.103 (<0.001) |
| Kinematic Velocity | 70 | 0.729 (<0.001) | −0.519 (0.088) | 34.557 (<0.001) |
| Load Platform | 280 | 0.706 (<0.001) | −5.565 (0.524) | 112.978 (<0.001) |
| KLT Acceleration | 280 | 0.654 (<0.001) | −0.847 (0.088) | 92.855 (<0.001) |
Correlation Coefficients and associated p-values were calculated using a Spearman Rank Correlation. The Coefficient Estimate, related Standard Error, Wald statistic and associated p-value were from the ordered multinomial multilevel models.
