摘　　要：目的探讨三维运动分析系统身体节段法对脑卒中偏瘫患者平衡功能测试的应用价值。方法对20例脑卒中偏瘫患者，进行Fugl-Meyer下肢运动功能评定、Brunel平衡等级量表、Berg平衡量表和5m起立·步行计时测验；同时采用三维运动分析系统身体节段法，分别进行坐位、立位和步行状态下的平衡功能测试。以Spearman秩相关系数对三维运动分析系统参数及运动功能、平衡量表的结果进行相关性分析。结果坐位及立位时，身体重心在水平面的摆动参数与下肢运动功能、平衡功能及步行能力的相关性均有统计学意义（P〈0．05）；步行时，仅身体重心前后向的摆动参数与下肢运动功能、平衡功能及步行能力的相关性有统计学意义（P〈0．05）；垂直方向的摆动参数除在坐位时与Brunel平衡等级的相关性有统计学意义（P〈0．05）外，在其它体位或活动状态时与患者的运动能力和平衡能力的相关性均无统计学意义（P〉0．05）。结论三维运动分析系统可以立体、动态、实时地监测人体在各种体位和功能动作时的平衡状况，对脑卒中患者的运动能力及平衡功能有一定的预示作用。Objective To investigate the clinical value of a three-dimensional motion analysis system by using the body segmental method for testing the balance of hemiplegic stroke patients. Methods Twenty stroke patients with hemiplegia were measured using the lower extremity Fugl-Meyer motor assessment （FMA-L） , the Brunel balance assessment （BBA） , the Berg balance sale （BBS） and a 5 m timed up-and-go test （Sm-TUGT）. The three-dimensional motion analysis system using the body segmental method was applied in three positions-sitting, standing and walking. Spearman＇s rank correlation coefficient was used to determine the extent of correlation between the values measured by the three-dimensional motion analysis system and the FMA-L, BBA, BBS and 5m- TUGT results. Results Some motion analysis variables （MSAx, MSVx, MSAy, MSVy and SPxy, SP3-D） are recorded in sitting and standing, while the center of gravity （COG） swing in the horizontal plane and some other variables （MSAx, MSVx and SPxy and SP3-D） are measured while walking. Anterior-posterior COG swing had a high negative correlation with the FMA-L, BBA and BBS scores and a high positive correlations with 5m-TUGT times. But except in sitting, MSAz and MSVz were both uncorrelated with FMA-L, BBA or BBS scores or with 5m- TUGT times. COG swing in the horizontal plane in sitting and standing apparently correlates with lower extremity motor function, balance, and walking ability. However, only the X axis swing parameters of the COG while walking correlated with lower extremity motor function, balance or walking ability. Conclusions A three-dimensional motion analysis system using the body segmental method can be used clinically to monitor patients＇ balance in real time and dynamically in different positions and activities, and it can be used to predict motor function and balance control in hemiplegic stroke patients.
