中风后的功能恢复受多种社会和环境因素的影响,且有个体差异,难于用客观或可信的指标进行预测。而发生上肢瘫痪是大脑中动脉梗塞后的一种严重的运动功能损害,对瘫痪上肢至今尚无临床检测法以正确预测功能恢复。目前主要依赖于主观临床评估,即开始发病时上肢功能丧失的严重程度作为重要依据。然而,感觉运动系统功能可通过诱发电位的测量提供感觉运动的整合和运动通路的情况,有可能作为较为客观和可信的指标。本研究的目的在于评估中风后亚急性期的体感诱发电位(SEPs)及运动诱发电位(MEPs)对瘫痪上肢功能恢复的预测价值。
The functional recovery after stroke is affected by many social and environmental factors, and there are individual differences. It is difficult to predict with objective or credible indicators. The occurrence of paralysis of the upper limb is a serious motor impairment after the middle cerebral artery occlusion. To the paralyzed upper limb there is no clinical test to correctly predict the functional recovery. At present, the main reliance on subjective clinical assessment, that is, the severity of the loss of upper limb function at the onset of the disease is an important basis. However, the sensory motor system function can provide sensory integration and motor pathways through the measurement of evoked potentials, possibly as a more objective and credible indicator. The aim of this study was to evaluate the predictive value of sub-acute somatosensory evoked potential (SEPs) and motor evoked potentials (MEPs) in the recovery of paralyzed upper limbs after stroke.
