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 foot on static posture (SPG). Methods: Thirty healthy subjects were divided into two groups: the feet were separated by 6 °, 10 cm, etc. Five kinds of foot test, the test sequence determined by a random number table. Results: There are differences between the five kinds of foot test values, the most unstable when the two feet are close together, the most stable when the feet are separated by 10cm in parallel. Conclusion: The foot position can affect the SPG measurement. For the patients with both feet standing upright, the bipedal position can be selected according to the patient’s balance condition.
