摘　　要：目的评估力反馈设备结合虚拟现实技术设计的虚拟盒块测试(virtual box and block test,VBBT)用于远程评估上肢运动功能的可行性。方法设计了一个VBBT系统用于评估上肢运动功能。该系统可用于计算受试者的VBBT得分、平均速度、运动谱弧长、耗能和平均抓握力。共招募20名健康受试者和16名脑卒中患者进行VBBT。结果脑卒中患者与健康受试者在VBBT参数的对比上均具有显著性差异(P<0.05);接收者工作特征(receiver operating characteristic,ROC)曲线表明,VBBT参数可区分脑卒中患者和健康受试者的表现(P<0.05)。脑卒中患者VBBT参数与传统临床评估的相关性分析结果表明,VBBT参数的共时效度;多元回归分析结果显示,VBBT的运动学和力学参数能够补充性解释传统临床评估。结论VBBT可用于远程评估脑卒中患者的上肢运动功能。Objective To evaluate the feasibility of virtual box block test(VBBT)designed by force feedback device combined with virtual reality technology for remote evaluation of upper limb moter function.Methods A VBBT system for upper limb motor function assessment was designed.This system could be used to calculate the VBBT score,mean velocity,spectral arc length,energy consumption and mean grasping force of the subjects.In total 20 healthy subjects and 16 post-stroke patients were recruited to perform the VBBT.Results Significant differences were found in all VBBT parameters(P<0.05)between post-stroke patients and healthy subjects.Receiver operating characteristic(ROC)curve analysis showed that the VBBT parameters were possible to distinguish the two groups(P<0.05).The correlations between VBBT parameters and traditional clinical assessments indicated the concurrent validity of the VBBT.Multiple regression analysis showed that the kinematic and kinetic parameters of the VBBT could partially explain the variance of the traditional clinical assessments.Conclusions The VBBT can be used as a remote assessment of upper limb motor function in post-stroke patients.
