足位对静态姿势描记结果的影响

Influence of foot position in the static posturography

目的 :研究足位对静态姿势描记 (SPG)的影响。方法 :对 30例健康受试者进行SPG ,分别采用双足跟并拢时 ,双足尖并拢、双足尖分开成 30°、双足尖分开成任意角度 ,以及双足平行分开 6cm、10cm等 5种足位进行测试 ,测试顺序由随机数字表确定。结果 :5种足位测试数值有差异 ,以双足跟尖并拢时最不稳定 ,双足平行分开 10cm站立时最稳定。结论 :足位能影响SPG测值 ;对于双足并拢直立困难者 ,可根据患者平衡状况 ,选择双足尖分开一定角度或双足平行直立的姿势进行检查。

Objective:To study the effect of position of the feet on posturography.Method:The quantitative significance of the standing position in posturographic measurements was evaluated with 30 healthy volunteers studied under nonvisual conditions,using 5 foot positions:heels toghther with the toes 30°apart or at an angle of the voleer's own choice ,and the feet parallel and 0,5 or 10 cm apart were studied respectively.Result:Five test methods showed different results.The feet parallel and 10 cm apart is the most stable position among 5 test methods,the most unstable position is feet parallel and together.Conclusion:Feet position can influence the results of test.For those who can hardly stand with the feet parallel and together can choose the feet apart position.
