摘　　要：背景:国外研究表明足姿与姿势稳定性存在一定关系。目的:基于足姿指数评分系统比较旋前足姿对姿势稳定性和本体感觉的影响。方法:以20-30岁的健康青年人为受试对象,根据右侧足姿指数评分分为旋前组(足姿指数评分>5)和中立位组(0≤足姿指数评分<5),每组15名。通过测试单腿站立时间评定每名受试者的优势腿和非优势腿,随后采用动静态平衡仪评估所有受试者双腿和单腿静态站立时压力中心摆动的长度和面积,在进行本体感觉测量时记录下肢的平均轨迹误差和完成时间。研究经广东省第二中医院伦理委员会审议通过[粤二中医(2019)伦审50号]。结果与结论:①30名受试者优势腿的压力中心位移长度明显小于非优势腿(P<0.01),平均轨迹误差明显大于非优势腿(P<0.05),二者压力中心位移面积及本体感觉测试完成时间比较差异无显著性意义(P>0.05);②单腿(右侧)静态站立时,旋前组的压力中心位移长度和位移面积大于中立位组(P<0.05),两组平均轨迹误差与本体感觉测试完成时间比较差异无显著性意义(P>0.05);③双腿静态站立时,旋前组的压力中心位移长度大于中立位组(P<0.05),两组压力中心位移面积比较差异无显著性意义(P>0.05);④结果表明,足姿是影响人体姿势稳定的重要因素,旋前足姿会降低人体的姿势稳定性,增加运动损伤及老人跌倒的风险。BACKGROUND:Studies outside China have shown that there is a certain relationship between foot posture and posture stability.OBJECTIVE:Based on foot posture index scale system,to compare the effect of pronated foot posture on postural stability and proprioception.METHODS:Thirty healthy youths aged from 20 to 30 years old were enrolled,and divided into two groups according to the right foot posture index:pronated group(foot posture index>5)and neutral group(0≤foot posture index<5)(n=15 per group).The leg standing with single leg for a longer time was defined as the dominant leg,and the other was the non-dominant leg.The length and area of center of pressure sway were evaluated by dynamic and static balance instrument.The average trajectory error and completion time of lower limbs were recorded during proprioception measurement.This study was approved by the Guangdong Second Traditional Chinese Medicine Hospital[YEZY(2019)LS50].RESULTS AND CONCLUSION:(1)In 30 subjects,center of pressure sway length in dominant leg was significantly lower than that in non-dominant leg(P<0.01),whereas average trajectory error was significantly larger in dominant leg than that in non-dominant leg(P<0.05).However,there was no significant difference in center of pressure sway area and completed time between two legs(P>0.05).(2)When tested with single-leg(right side)static stance,sway area and length of pressure center were larger in pronated group than that in neutral group(P<0.05),but proprioception including average trajectory and completed time was not significantly different between the two groups(P>0.05).(3)When tested with two-leg static stance,sway length of pressure center was larger in pronated group than that in neutral group(P<0.05);sway area of pressure center was not significantly different between the two groups(P>0.05).(4)Results confirmed that foot posture exerts a significant effect on postural stability.Pronated foot can reduce postural stability,which will increase sports injury and the risk of fall in the elder.
