    科学领域:

    • 神经科学是一个神经科学.
    • 生物医学工程 生物医学工程
    • 疼痛管理 疼痛管理

    背景情况:

    • 慢性肌肉骨 (MSK) 疼痛与不适应性大脑可塑性有关,特别是大脑活动发生变化.
    • 对于慢性MSK疼痛的现有治疗方法不能针对这些大脑活动变化.
    • 之前使用电脑图 (EEG) 的研究表明,慢性MSK疼痛患者在运动期间体感皮质的事件相关α功率增加.

    研究的目的:

    • 开发和测试一种低成本的神经反系统,旨在降低与运动相关的事件相关的α功率.
    • 评估系统在健康参与者的四肢运动期间调节α功率的有效性.

    主要方法:

    • 创建了一个新型的低成本神经反系统,集成了运动检测的电肌图 (EMG) 和对体感皮层的α功率测量的EEG.
    • 一个图形用户界面 (GUI) 提供了基于提取的α功率的实时视觉反.
    • 该系统在一次会议中进行了评估,四名健康参与者在五个区块中执行膝盖和肘部运动.

    主要成果:

    • 所有参与者都在一次训练中成功调节了与运动相关的α功率 (p<0.05).
    • 在第一个和最后一个训练区之间观察到阿尔法功率显著减少40%.
    • 这些发现表明,该系统在短时间训练后在四肢运动期间改变阿尔法功率的能力.

    结论:

    • 开发的低成本神经反系统有效地使健康参与者能够调节与运动相关的α功率.
    • 该系统显示出作为一种非侵入性干预的潜力,用于解决慢性MSK疼痛中的不适应性可塑性.
    • 需要在慢性MSK疼痛患者中进行进一步的研究和验证.
