目的:采用复合方法选取测试本体感觉功能的敏感性角度指标。方法:选择普通健康人60名,使用BIODEX PRO SYS 3等速系统测定膝关节主动/被动位置觉,使用X-SENS测试系统测定三维位置觉及运动觉,利用SPSS17.0统计软件分析测试指标。结果:因子分析结果显示,主动左、右侧关节位置觉30°,被动左侧关节位置觉30°和被动左、右侧关节位置觉60°,左、右侧运动觉60°和三维位置觉为测评膝关节本体感觉功能的敏感性角度指标;总体变异系数、指标变异系数及变异系数派生指标结果显示,主动左、右侧关节位置觉30°,被动左、右侧关节位置觉60°,左、右侧运动觉60°为测评膝关节本体感觉功能的敏感性角度指标。结论:测评膝关节本体感觉功能的敏感性角度指标为主动位置觉30°、被动位置觉60°、运动觉60°和三维位置觉。
OBJECTIVE: To select the sensitive angle index of the sensory function of the test ontology by compound method. Methods: Sixty normal healthy subjects were selected. The knee joint active / passive position was measured by the BIODEX PRO SYS 3 system. The X-SENS test system was used to measure the three-dimensional position and motor perception. SPSS 17.0 was used to analyze the test parameters. Results: The result of factor analysis showed that the position of the active left and right joints was 30 °, the position of the passive left joint was 30 °, the position of the passive left and right joints was 60 °, the movement of the left and right side was 60 ° and that of the three-dimensional position The results showed that the position of active left and right joints was 30 °, the position of passive left and right joints was 60 °, Left and right side of the movement of 60 degrees for the evaluation of knee joint sensory function of the sensitivity of the angle indicators. Conclusion: The sensitivity of the knee joint sensory function is 30 ° for the active position, 60 ° for the passive position, 60 ° for the movement and three-dimensional position perception.
