Analysis of knee joint motions in step cycle in young and adult men of 17-25 years
The data received with the help of capture system and movement analysis helped to determine the cinematic parameters of knee joint in step cycle of 25 men aged 17-25 with normosthenic body type. The amplitude of motions in a knee joint was: in flexion- 53.8±1.2°; knee axis rotation - 9.4±0.4°; lateral knee displacement - 12.9±0.5°. The correlation analysis revealed the strong link between knee joint flexion and lateral knee displacement and its axis rotation. The factor of weak power association may indicate the knee joint stability in extension and mild power indicates the less stability in its flexion.
