Table 2.
For the first eight principal movements (PM1–8), the relative explained variance (rVAR (%)), the plane in which the PM motion mostly takes place, and a qualitative description of the PMs.
| PM | rVAR [%] | Main Plane of Motion |
Main Movements |
|---|---|---|---|
| 1 | 44.2 ± 11.3 | Frontal (Mediolateral) |
Hip strategy coupled with ankle supination/pronation and knee flexion/extension of the stance leg, and hip adduction/abduction and flexion/extension of the lifted leg |
| 2 | 26.0 ± 13.2 | Sagittal (Anteroposterior) |
Ankle strategy |
| 3 | 7.6 ± 5.7 | Diagonal (Anterolateral) |
Hip strategy coupled with ankle supination/pronation of the stance leg, and the combination of hip abduction/adduction and knee flexion/extension of the lifted leg |
| 4 | 7.0 ± 3.9 | Frontal (Mediolateral) |
Hip strategy coupled with knee flexion/extension and ankle supination/pronation of the stance leg, and knee flexion/extension of the lifted leg |
| 5 | 3.2 ± 3.0 | Frontal (Mediolateral) |
Hip strategy coupled with ankle supination/pronation of the stance leg, and the combination of hip flexion/extension and abduction/adduction of the lifted leg |
| 6 | 2.5 ± 1.6 | Diagonal (Oblique- transverse) |
Upper-body oblique rotation to the lifted leg coupled with hip flexion/extension of the lifted leg |
| 7 | 2.0 ± 2.5 | Vertical | Breathing movement patterns: upward/downward moving of the shoulders coupled with knee flexion/extension of the stance leg, and the combination of hip and knee flexion/extension of the lifted leg |
| 8 | 1.6 ± 1.2 | Vertical | Hip and knee flexion/extension of the lifted leg coupled with slightly upward/downward moving of the shoulder, and ankle dorsiflexion/plantarflexion of the stance leg |
