背景和目的：本研究的目的是确定上肢短潜伏期躯体感觉诱发电位(USEP)对首发中风患者优势半球的预测能力。方法：对19例患者(平均年龄58岁)进行两次评估：到达康复中心时，中风后约3周，约10周后再次评估。临床评估包括运动能力、日常生活活动独立性和沟通能力的定量评估。在最初临床评估的一周内记录USEP。结果：7例未检测到皮层电位的患者预后最差，其余12例患者皮质电位的存在并不能准确预测其“康复能力”(即病情进展的程度)。在两个半球上记录的电位的幅度与交流能力的变化之间建立了相关性。其他发现还包括卒中后第一个月受损大脑半球中枢传导时间缩短与运动能力改善之间的关系。结论：USEP可以作为预测卒中患者康复进程的辅助工具。
Background and Purpose: The aim of this study was to determine the predictive yield of upper limb short latency somatosensory evoked potential (USEP) in patients with first stroke in the dominant hemisphere.Methods: Nineteen patients (average age, 58 years) were evaluated twice: on arrival at the rehabilitation center, approximately 3 weeks after the stroke, and again approximately 10 weeks later. The clinical assessment included a quantitative evaluation of motor ability, independence in activities of daily living, and communication ability. USEP was recorded during the week of the initial clinical evaluation. Special attention was paid to the relations between USEP parameters and the dynamics of the clinical condition.Results: The seven patients in whom no cortical potential could be detected showed the worst outcomes, however, the existence of cortical potentials in the remaining 12 patients did not provide a precise prediction of their ''rehabilitative capacity'' (ie, the extent of their progress). A correlation was established between the amplitude of the potentials recorded over both hemispheres and changes in communication ability. Additional findings included an association between shortened central conduction time over the damaged hemisphere during the first month after stroke and improvement in motor ability.Conclusions: USEP can serve as an adjuvant tool for predicting the recovery progress of stroke patients.
