摘要
目的应用不依赖穿戴设备的新型步态辅助医学诊疗系统,验证其可行性、实用性、准确性。方法选取60名受试者为研究对象,按自身对照研究方法先后用新型步态辅助医学诊疗系统与Vicon运动捕捉系统测试步态,受试者以3种速度行走(快速、常速、慢速)。测试数据分2组:新型步态辅助医学诊疗系统测试数据为试验组,Vicon运动捕捉系统测试数据为对照组,比较两组步态测试数据的差异性。结果受试者在快速、常速行走中,试验组左右侧的步频、单步时间、跨步时间与对照组同名侧比较差异均无统计学意义(P>0.05),试验组左右侧的步长、步幅、步宽、步速与对照组同名侧比较差异均有统计学意义(P<0.05)。受试者在慢速行走中,试验组左右侧的步频、单步时间、跨步时间、步长、步幅、步速与对照组同名侧比较差异均无统计学意义(P>0.05),试验组左右侧的步宽与对照组同名侧比较差异均有统计学意义(P<0.05)。受试者在快速、常速、慢速行走中,试验组左右侧髋关节最大屈曲角度与对照组同名侧比较差异均无统计学意义(P>0.05),试验组左右侧髋关节最大伸展角度、膝关节最大屈曲角度、膝关节最大伸展角度、踝关节最大跖屈角度、踝关节最大背伸角度与对照组同名侧比较差异均有统计学意义(P<0.05)。受试者在常速行走,右侧为例的情况下,试验组时空参数(步频、单步时间、跨步时间、步长、步幅、步速)以及髋、膝、踝关节的最大屈曲和伸展角度与对照组同名数据具有很高相似度,变化趋势基本保持一致;两组数据基本都在文献报道的步态数据参考范围的低值与高值之间。结论新型步态辅助医学诊疗系统不依赖穿戴设备、操作简单、经济、依从性好,具有检测步态的可行性、实用性、相对准确性,值得临床逐步应用及推广。
Objective The feasibility,practicality,and accuracy ofa newly developed gait-assisted medical diagnosis and treatment system thatdoes not rely on wearable devices was verified.Methods Sixty subjects were enrolled and the gait using the same three speeds(fast,constant,and slow)was tested according to the self-control research method.The test data were divided into two groups(the experimental group with the new gait-assisted medical diagnosis and treatment system and the control group with the classic Vicon motion capture system).The differences between the two groups were compared.Results When the subjects were walking at fast and constant speeds,there was no significant difference in step frequency,step time,and stride time between the left and right sides of the experimental group and the same side of the control group(P>0.05).The step length, stride length, step width, and step speed of the experimental group were significantly different from the control group (P<0.05). When the subjects were walking slowly, there was no significant difference in the step frequency, step time, step time, step length, stride length, and step speed between the left and right sides of the experimental group and the control group (P>0.05). There was a significant difference in the step width between the left and right sides of the experimental and control groups (P<0.05). There was no significant difference in the maximum flexion angle of the left and right hip joints between the experimental and control groups (P>0.05). The maximum extension angle of the left and right hip joints, the maximum flexion angle of the knee joint, the maximum extension angle of the knee joint, the maximum flexion angle of the ankle joint, and the maximum extension angle of the ankle joint in the experimental group were significantly different from the control group (P<0.05). When the subjects were walking at a constant speed and using the right side as an example, the time and space parameter data (step frequency, step time, stride time, step length, st
