Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Calculation items are knee flexion, valgus, internal rotation angle, maximum vertical ground reaction force. The analysis section is the stop period from the foot contact to the maximum knee flexion position and the movement period from the maximum knee flexion position to the toe-off. Foot contact is defined as the point when the vertical ground reaction force exceeds 10 N, and the toe-off is defined as the point when the vertical ground reaction force falls below 10 N. The analysis section is normalized to 100%. All evaluations are performed three times, and an average value of three times is used as a representative value of the object for analysis. | — |
