A Study of the Rotational Movements of the Knee during Walking and Running at Different Speeds

초록

The purpose of this study is to investigate the kinematic parameter of knee rotational movement in the gait transition from slow walking, normal walking to running. Twenty male subjects were participated in the study (Age: 22.3±1.72 years, Height: 175.65±5.50 cm, Weight 76.3 ±10.12 kg). The subject walked in treadmill with the velocity of 2km/hr, 4km/hr, and 6km/hr, kinematic data obtained were classified into 3 speed groups. Group 1 was slow walking (2km/hr), Group 2 normal walking (4 km/hr), Group 3 running (6km/hr). The range of motion and maximum value were analyzed. The range of motion of flexion/extension and internal/external were found maximum at group 3 and minimum at group 1. Whereas, no statistically significant difference were seen in the peak of adduction/abduction over the whole of the gait cycle. Finding of this study suggest that there is greater rotational movement of the knee joint during running than in slow and normal walking.
