摘要:
目的 观察分析不同年龄段平衡功能的不同表现,以及造成这种差异的主要因素.方法 将109例受试者按年龄划分为青少年组、中青年组和老年组.使用Swaystar检查装置记录7项平衡试验中躯体前后、左右晃动的角位移和晃动总面积.结果 (1)当视觉、本体觉或前庭觉传入信息受到干扰时,老年组平衡功能明显较差;单左腿站立时,老年组躯体晃动幅度明显大于另外两组(P<0.05),然而单右腿站立时,三组之间无统计学差异;(2)青少年阶段的姿势调节主要依赖于视觉.结论 随着年龄的增加,本体觉和前庭觉减退会导致平衡功能的降低;而在青少年时期视觉在姿势调节过程中占主要地位.

Comparing the contributions to postural control among different age groups of healthy population
()
Abstract:
Objective The aim of this study was to compare the contributions of possible differ- ences to postural control in different ages. Methods Seven balance tests were administered to 109 subjects,aged between 13-79 years. The subjects were divided into three groups according to their age. The ranges of angular displacement in the pitch and roll direction and total angle areas were recorded using Swaystar system. Results (1) Compared with the other two groups,the senior group had a poorer performance when the afferent information of sensory,visual or vestibular systems were disturbed, and had greater sway amplitude in left leg stance test; (2) The adolescent group rely more strongly on vision to stabilize their body. Conclusions We concluded that all of the three factors associated with the postural control,especially the proprioceptive and vestibular systems, showed significant association with age, and attention should be directed toward these phenomena.
