Description of principal movement components PMk. Statistically significant correlations between center of pressure (COP)-sample entropy (SaEn) and Principal movement strategies (PM) variables are symbolized by *.
| k | EV (Eigenvalues) (%) | Correlation | Main Strategy (Directions) | Specifications/Additional Features |
|---|---|---|---|---|
| 1 | 77.77 | * | Ankle sway (anterior/posterior) | No visible motions in the rest of the body. |
| 2 | 9.71 | * | Ankle sway (medial/lateral) | No visible motions in the rest of the body. |
| 3 | 4.73 | Hip strategy (flexion/extension) | Resulting upper body sway (posterior/anterior) visible. |
