步行速度在脑卒中患者运动功能恢复评定中的价值

目的探讨步行速度在脑卒中偏瘫患者运动功能恢复评定中的价值。方法对 5 5例患者进行 10m最大步行速度(MWS)的评价、简式Fugl Meyer法下肢运动功能评价 (FMA L)、Motricity指数下肢评价 (MI L)、Berg平衡评价 (BBS)和FIM的转移和行进能力评价 (FIM A)。另选择 10例年龄相仿健康成人进行 10m最大步行速度评测作为标准对照值。按实用步行速度的要求将患者分成 3组。用Pearson相关分析最大步行速度与临床变量之间的关系。结果低速组患者的MWS与其MI L、FMA L、BBS和FIM A之间存在中度相关性 (r =0 5 81-0 770 ,P <0 0 5 ) ;而中速组和快速组的MWS与其MI L、FMA L、BBS和FIM A之间不存在相关性 (r =0 0 16-0 3 80 ,P >0 0 5 )。步行速度达到 44 8m /min(或标准值的 41 3 % )以上时 ,步行速度与平衡、肌力、运动模式和移动能力之间的关系明显被消弱。结论步行速度在脑卒中患者功能结局评定上是一个独立的变量。

Value of walking speed at the evaluation of motor function recovery in hemiparetic patients after stroke

ObjectiveTo identify the value of walking speed at the evaluation of motor function recovery in hemiparetic patients after stroke.MethodsFifty-five cases were assessed in the study. The walking speed, motor function, strengths of the paretic lower limb,balance and ambulation of ADL function were evaluated with the 10m Maximum Walking Speed Test,Fugl-Meyer Assessment, Motricity Index, Berg Balance Scale and ambulation item of Functional Independence Measure. The level of association between walking speed and the clinical variables were examined with Pearson's correlation coefficients.ResultsIn the slow group, the gait-related clinical scores were related to walking speed (Pearson's r=0.581-0.770,P<0.05),while that in the moderate group and fast group were not (Pearson's r=0.016-0.380,P>0.05).The correlation between the gait-related clinical scores and walking speed was weakened when walking speed above 44.8m/min(or 41.3% of normal values).ConclusionWalking speed plays an independent role as an indicator of improved performance.
