摘要
目的:探讨身体节段法三维运动分析在脑卒中偏瘫患者平衡测试中的信度、效度和敏感度,为该检测方式的临床应用提供客观依据。方法:20例有平衡障碍的脑卒中偏瘫患者(病例组或A组)和20例年龄、身高、体重与之相匹配的健康人(对照组或B组),在两天内分别接受身体节段法三维运动分析系统和Pro-KineLine平衡反馈仪的测试,每种测试进行2次。对三维运动分析系统的2次结果采用组内相关系数(ICC)检验其重测信度;对三维运动分析系统和平衡反馈仪的测试结果采用Spearman秩相关分析法以检验三维运动分析系统的效度;对两组受试者的三维运动分析系统测试结果采用独立样本t检验,以检测三维运动分析系统的敏感度。结果:①两组受试者坐位及立位下三维运动分析系统各参数的重测信度良好(坐位ICC:A组为0.621—0.979,B组为0.672—0.980;立位ICC:A组为0.653—0.934,B组为0.613—0.974)。②两组受试者的三维运动分析系统与平衡反馈仪相对应的参数之间均有中到高度的相关性(A组:坐位r=0.636—0.793,立位r=0.716—0.883;B组:坐位r=0.453—0.700,立位r=0.495—0.628);③A组的三维运动分析各项参数与B组比较,差异均有显著性(P<0.05)。结论:身体节段法三维运动分析具有较高的信度、效度和敏感度,可以用于脑卒中偏瘫患者的平衡功能检测。
Objective： To investigate the reliability, validity and sensitivity of balance test with three-dimensional motion analysis system by segmental method on stroke patients with hemiplegia, and to provide evidence for the clinical application of this balance test. Method： A total of 20 stroke patients with hemiplegia who had balance disorder （patient group or A group） and 20 health people matched in age, height and weight （control group or B group） took tests with the three-dimensional motion analysis system by segmental method and Pro-Kine Line balance feedback apparatus twice in two days, respectively. The reliability, validity and sensitivity of the tests were analysed. Result：①Test-retest reliability in variables of the three-dimensional motion analysis system by segmental method in two groups were fairly good. ②There were moderate to high correlations between each corresponding variables of the three-dimensional motion analysis system and the balance feedback apparatus in two groups.③There were significant differences between A group and B group in variables of the three-dimensional motion analysis system. Conclusion： There were good reliability, validity and sensitivity in three-dimensional motion analysis by segmental method, and it can be used to evaluate the balance function in stroke patients with hemiplegia.
