重心平衡测定仪检测人体平衡功能

Quantitative evaluation of balance function in normal with stabilometer

采用重心平衡测定仪测试人体的姿势图及有关参数。正常人重心摆动轨迹分为中心型、前后型、左右型、多中心型、弥散型5种类型 ,以中心型为主。正常人不同年龄组各参数比较 ,20～30岁组平衡功能最佳 ,重心摆动面积小、轨迹短、速度慢 ,随着年龄增加平衡功能逐渐减退 ,50岁以后明显减退。重心平衡测定仪可做为眩晕、前庭病变、脑部病变辅助诊断和康复功能评测定量指标 ,能客观、定量评价人体静立平衡功能 。

A measurable parameter in the study of static equilibrium was described.The locus of postural sway was measured with a set of computer during 1 minute period .There are five patterns of postural sway:centripetal,forward backward,right left,diffuse and multicentric patterns;centripetal pattern was the most prominent figure pattern in normal subjects.The length of locus was the shortest and velocity of sway was the slowest in the 20～30 year group.The age was related to stabilization positively,the older,the poorer the stabilization is .This instrument could be used to assess the standing stability objectively and quantitatively.
