设计了一个针对多发性硬化症患者的三维步态分析实验,利用三维光学捕捉系统对实验被试身体不同部位标记点的三维坐标进行追踪和记录,成功发现了多个步态参数发生的变化,这些变化不仅能反映实验被试细微的步态功能上的变化,而且还与接受治疗的时间密切相关。此套基于步态数据的量化评估体系能够弥补目前广泛应用的评估方法主观和不够准确的缺点,为临床医生改进治疗方案以及制定更加有效的治疗方法提供帮助。

A study focused on the 3D gait analysis for the multiple sclerosis patients is designed. A 3D motion capture system is used to track the changes in gait performance involving the selected parameters before and after the treatment, and some changes of multiple gait parameters are successfully found. These changes reflect the subtle functional changes of the patients, and it is also found that the subtle functional changes are closely related to the treatment time. The quantities evaluation based on the gait data is able to compensate the disadvantages caused by the currently widely used evaluations. These objective assessments will assist the clinicians with making more effective treatment decisions and with facilitating new treatment development.
