Abstract

OBJECTIVE

Patient engagement is of major significance in neural rehabilitation. We developed a real-time EEG marker for attention, the Brain Engagement Index (BEI). In this work we investigate the relation between the BEI and temporary functional change during a rehabilitation session.

METHODS

First part: 13 unimpaired controls underwent BEI monitoring during motor exercise of varying levels of difficulty. Second part: 18 subacute stroke patients underwent standard motor rehabilitation with and without use of real-time BEI feedback regarding their level of engagement. Single-session temporary functional changes were evaluated based on videos taken before and after training on a given task. Two assessors, blinded to feedback use, assessed the change following single-session treatments.

RESULTS

First part: a relation between difficulty of exercise and BEI was identified. Second part: temporary functional change was associated with BEI level regardless of the use of feedback.

CONCLUSIONS

This study provides preliminary evidence that when BEI is higher, the temporary functional change induced by the treatment session is better. Further work is required to expand this preliminary study and to evaluate whether such temporary functional change can be harnessed to improve clinical outcome.

CLINICAL TRIAL REGISTRATION

Registered with clinicaltrials.gov, unique identifier: NCT02603718 (retrospectively registered 10/14/2015).

摘要

目的

患者参与在神经康复中具有重要意义。我们开发了一种用于注意力的实时 EEG 标志物，即大脑参与指数（BEI）。在这项工作中，我们研究了 BEI 与康复过程中临时功能变化之间的关系。

方法

第一部分：13 名未受损的对照者在进行不同难度的运动锻炼时接受 BEI 监测。第二部分：18 名亚急性脑卒中患者在进行标准运动康复治疗的同时，根据其参与程度使用实时 BEI 反馈。基于给定任务前后的视频，评估单次治疗的临时功能变化。两名评估者，对反馈使用情况不知情，评估单次治疗后的变化。

结果

第一部分：运动难度与 BEI 之间存在关系。第二部分：无论是否使用反馈，临时功能变化都与 BEI 水平相关。

结论

本研究初步证明了当 BEI 较高时，治疗期间引起的临时功能变化更好。需要进一步的工作来扩展这项初步研究，并评估这种临时功能变化是否可以被利用来改善临床结果。
