目的：探究虚拟现实（VR）心理旋转系统在临床康复中的可用性和特征参数。
方法：招募15例健康受试者、10例脑损伤患者和4名治疗师进行VR心理旋转系统的可用性测试，健康受试者另外接受传统E-prime心理旋转测试。分别采用系统可用性量表(SUS)、模拟器不适感量表(SSQ)和半结构式访谈收集系统的可用性得分、晕动症程度和主观反馈。
结果：VR心理旋转与传统E-prime心理旋转相比，平均反应时(t=0.424， P=0.680)与正确率(t=1.865， P=0.6)无显著性差异，且具有相似的反应时-旋转角度变化趋势。健康组SUS为（77.0±11.4）分，患者组SUS为（60.0±12.3）分，可用性处于“Good”水平。健康组与患者组SSQ平均得分为10.22分和6.73分，VR晕动症不明显。半结构式访谈表明系统整体可用性较好，但硬件、反馈、训练等模块需继续完善。
结论：基于VR的心理旋转系统具有良好的可用性，有潜力给临床康复带来全新的运动想象评估与训练形式。 |

| Abstract
Objective：To explore the usability and characteristic parameters of mental rotation system based on virtual reality (VR) in clinical rehabilitation.
Method：A total of 15 healthy volunteers， 10 patients with brain injury and 4 physiotherapists were recruited to perform the usability test of VR-based hand mental rotation task（HMRT）. The healthy volunteers also received the traditional HMRT based on E-prime software. The system usability scale (SUS)， simulator discomfort scale (SSQ)， and semi-structured interviews were used to collect the system's usability score， VR motion sickness degree and feedback on the use of the system， respectively.
Result：There was no significant difference in the average reaction time (t=0.424， P=0.680) and the correct rate (t=1.865， P=0.6) between VR and traditional E-Prime mental rotation， and they had similar 'accuracy-angle' trend. The SUS score was (77.0±11.4) in healthy subjects and (60.0±12.3) in patients with brain injury， and the overall usability range was at “Good” level. The average SSQ score were 10.22 and 6.73 in healthy subjects and patients， indicating no obvious sickness. The semi-structured interview reflected that the comfort of hardware， the form of feedback， training elements needed to be further improved.
Conclusion：The VR-based HMRT demonstrates overall good usability and has the potential to bring a new form of evaluation and training for motor imagery in clinical rehabilitation. |
