보행속도에 따른 운동형상학적 특성 = Kinematic Characteristics at Different Speeds of Walking

다국어 초록 (Multilingual Abstract)

Kinematic characteristics at different speeds of walking are important to understand the basic mechanisms of locomotion. Fourteen men with no history of neuromusculoskeletal disorder were studied with three dimensional motion analysis system during walking with 5 different speeds (57.11-99.09m/min). Time parameters, distance parameters, and kinematic analysis of ankles, knees, hips, and pelvis on sagittal, coronal, and transverse planes were compared with each other on different walking speeds.
It is found that increasing walking speed
1. increased stride length and stride length raio, but decreased the step length and step length ratio.
2. increased the angle of ankle, knee & hip joint on sagittal plane during early and late stance period, due to the greater forces at heel-strike and toe-off.
3. did not change the kinematic characteristics of ankle, knee & hip joints on 3 planes during the swing phase.
The result of this study can be usefully utilized as the basic data to design and evaluate prosthetic devices, and to detect abnormal gait performances.
