评估电子步道在步行运动学参数采集中的可靠性。37名男性志愿者参与到实验中,年龄在21岁到32岁之间,所有受测者都是健康的个体。在实验中,分别以自选的慢走、正常走和快走三个模式采集步行中的步长、步频和步速。研究结果显示电子步道在测量步态时空参数时具有很高的可靠性,还展示了可靠系数分别达到0.75和0.9所需的测试次数。当利用电子步道采集不同速度模式下的步态参数用于实验研究时(可靠系数大于0.9),至少需要3次测量。
Evaluate the reliability of electronic trail in walking kinematics acquisition. Thirty-seven male volunteers participated in the experiment, aged 21 to 32, all of whom were healthy individuals. In the experiment, the steps, stride and pace of walking were acquired by three modes of walk, walk and walk respectively. The results show that the electronic walkway is highly reliable in measuring gait space-time parameters and also shows the number of tests needed to achieve a reliability factor of 0.75 and 0.9, respectively. When using the electronic trail to acquire gait parameters at different speed modes for experimental studies (reliability coefficient greater than 0.9), at least 3 measurements are required.
