摘要
步态分析可以客观、定量地反映偏瘫患者步态的异常,在临床中应用广泛,但多年来一直缺乏多种步态参数综合反映步态异常的方法。步态分析系统通过设计基于六轴数据传感器的数据采集收发模块,对采集到的六轴运动数据用LabVIEW进行处理,得出步长、髋膝关节角度。通过系统测试,对系统的稳定性和精度进行了验证,测试结果表明:该步态分析系统方便快捷,可以很好地对病人的步态的相关参数进行采集和存储,为医生对病人病情的分析提供参考,具有性能稳定、微型、低功耗、成本低、方便便携等特点。
Gait analysis can reflect the abnormality of hemiplegic patients objectively and quantificationally,it is widely used in hospital,but lacking a method that can reflect many kinds of gait parameters synthetically all years long.Gait analysis system can collect data and process them with LabVIEW based on data receiving and transmitting module using six-axis sensor,and stride and angles of hip joint and knee can be calculated from it.The experiment shows that,the stability and precision of gait system can be tested,gait system is of great convenience,and can fulfil the task of collecting and saving the gait parameters of patients,it can be used as reference for doctors for analysis on patients＇ illness,in a word,the gait anaylsis sytem has many characteristics,such as stability,small size,low power consumption,low cost,portability and so on.
