Although the study of Learning is extremely relevant to the endeavor of functional rehabilitation of brain injured patients, there has been little effort to directly apply* learning principles to the rehabilitation setting. Contextual interference refers to the finding that practice occurring interspersed with other tasks leads to greater long term retention than blocked practice (random practice effect). Also, practice on more than one variant of a task leads to better long term retention' on. and better ability to use the skill flexibly (variable practice effect). It appears therefore, that contextual interference results in outcomes that are precisely the goals of neurorehabilitation (long term flexible retention). There are however reasons that suggest some groups may not benefit from, or may even be hindered by, contextual interference. The primary goals of the proposed studies are to; (1) examine the effect of contextual Interference on motor skill relearning in stroke patients: (2) identify factors in patients undergoing rehabilitation post stroke that indicate whether contextual interference training is beneficial; (3) relate the location and changes in size of the infarction visualized with Magnetic Resonance Imaging with skill relearning improvements over time; and (4) develop training paradigms employing contextual interference that could be adopted readily in the neurorehabilitation clinic.

虽然学习的研究是非常相关的， 为脑损伤患者的功能康复所做的奋进， 一直很少努力直接应用 * 学习原则， 康复环境。 背景干扰是指 实践与其他任务交织在一起， 长期保持比封闭的做法（随机实践效果）。 此外，在一项任务的多个变体上进行练习， 长期保持'on.和更好的能力，灵活地使用技能 （可变的实践效果）。 由此看来， 干扰导致的结果正是 神经康复（长期灵活保留）。 然而存在 原因表明，一些群体可能不会受益于，甚至可能是 受到背景干扰的阻碍。 拟议研究的主要目标是：（1）检查 情境干预对脑卒中运动技能再学习影响 患者：（2）确定患者接受康复治疗的因素 中风后，表明是否上下文干扰训练是 （3）在位置和大小的变化， 磁共振成像技术显示梗死 随着时间的推移，重新学习改进;（4）开发培训模式 使用上下文干扰，可以很容易地在 神经康复诊所
