The use of a treadmill to evaluate gait patterns makes it possible to analyze many gait cycles and stride to stride variations. The objective of this study was to assess the time required for a subject to habituate to walking on a treadmill. The evolution of knee kinematics and spatio-temporal parameters were analyzed to measure habituation to walking on the treadmill. To obtain this information, data were recorded on 10 healthy subjects for about 45 minutes as they walked on a treadmill. A steady state was attained for knee kinematics and most spatio-temporal parameters at the time the treadmill had attained its maximal speed (approximately 30 seconds). However, 10 minutes were necessary for stride length to become reproducible. Time for habituation to walking on a treadmill must be considered when kinematics are evaluated during gait of healthy and disabled subjects. We have shown that, at least for young, healthy individuals who are non-naïve to walking on a treadmill, a 10-minute warm-up is enough before three-dimensional knee kinematics and spatio-temporal data can be recorded.
使用跑步机评估步态模式能够分析多个步态周期以及步幅间的变化。本研究的目的是评估受试者适应在跑步机上行走所需的时间。分析膝关节运动学和时空参数的变化，以衡量对在跑步机上行走的适应情况。为获取此信息，记录了10名健康受试者在跑步机上行走约45分钟的数据。当跑步机达到最大速度时（约30秒），膝关节运动学和大多数时空参数达到稳定状态。然而，步长变得可重复需要10分钟。在评估健康和残疾受试者的步态运动学时，必须考虑适应在跑步机上行走的时间。我们已经表明，至少对于熟悉在跑步机上行走的年轻健康个体，在记录三维膝关节运动学和时空数据之前，10分钟的热身就足够了。
