虚拟现实技术在脑卒中运动康复中的应用现状

Status of Application of Virtual Reality Technique in Motor Rehabilitation in Stroke(review)

脑卒中患者的运动康复是虚拟现实技术应用的一个新领域。研究者们研制和利用不同的虚拟现实训练系统,对可能的影响因素进行观察后发现,光流速度、输出设备差异和提供反馈的类型均影响虚拟治疗的效果。对不同病程脑卒中患者疗效的研究证实,虚拟现实技术不仅能够改善脑梗死偏瘫患者的上肢和下肢运动功能,而且能够提高患者的日常生活能力;与机器人、减重平板训练等联合使用的初步结果安全有效。并在影像学研究方面找到支持使用虚拟现实技术的部分证据。这些研究对于虚拟现实技术的应用前景具有重要的临床意义。

Using virtual reality（VR）-based technology in motor rehabilitation for stroke patients is a new field. The researchers developed different kinds of VR-based training systems and used those existed. They found some possible variables that influenced outcome, including optic flow, different output device and feedback type that provided. The data from the stroke patients with hemiparesis in different stages demonstrated that training with VR-based training paradigms contributed in motor function and activities of daily living. Moreover,they also proved that training with VR-based training systems combined with robot and/or partial body weight-supported treadmill training was safe and effective. It also presented some evidences that supported VR-based technology in the neuroimaging studies. Overall, these studies had important clinical implications for the development of future VR training protocols.
