虚拟现实技术在轻度认知障碍患者认知康复训练中的应用

Application of Virtual Reality Technology in Cognitive Rehabilitation Training in Patients with Mild Cognitive Impairment

目的:探讨虚拟现实认知康复训练对改善轻度认知障碍(MCI)患者认知功能、日常生活能力和睡眠质量的效果。方法:60例MCI患者随机分为常规组和虚拟组,每组30例。常规组行常规认知训练,虚拟组行虚拟现实认知康复训练,疗程均为6周。在训练前及训练6周后采用蒙特利尔认知评估量表(MCOA)、简易智能精神状态量表(MMSE)、日常生活能力量表(ADL)、匹斯堡睡眠质量指数量表(PSQI)和半结构式访谈来评价2种认知康复训练的临床疗效。结果:康复后,2组的MoCA、MMSE和ADL评分均高于同组康复前,且虚拟组高于常规组(P<0.05);2组的PSQI评分与同组康复前差异无统计学意义(P>0.05),且2组间差异无统计学意义(P>0.05)。访谈结果显示,虚拟组患者均认为虚拟现实技术能提高其认知功能,并愿意继续虚拟现实技术下的认知康复训练;常规组部分患者表示训练后认知功能没有明显变化。结论:虚拟现实认知康复训练改善MCI患者的认知系统功能的疗效优于传统康复方法。

Objective:To explore the effect of virtual reality(VR)technology cognitive rehabilitation training on improving cognitive function,daily life ability,and quality of sleep in patients with mild cognitive impairment(MCI).Methods:Sixty MCI patients were randomly divided into routine and VR groups of 30 each.The routine group used conventional cognitive training methods,and the VR group used cognitive rehabilitation training based on VR technology.Rehabilitation lasted 6 weeks for all patients.Before and 6 weeks after rehabilitation training,the Montreal Cognitive Assessment Scale(MoCA),Mini-Mental State Examination(MMSE),activity of daily living scale(ADL),Pittsburgh sleep quality index(PSQI),and semi-structured interviews were used to eval-uate the clinical efficacy of the trainings.Results:After rehabilitation,the MoCA,MMSE,and ADL scores of both groups improved compared to the same group before training,and the VR group showed a greater improve-ment(P<0.05).The PSQI scores did not show a significant difference before and after training in either group(P>0.05),and there was no significant difference between the groups(P>0.05).The semi-structured interview re-vealed that all patients in the VR group believed that cognitive rehabilitation training under VR improved cogni-tive function and were willing to continue VR cognitive rehabilitation function training.The routine group ex-pressed satisfaction with the training outcome,while some patients reported no significant change in cognitive function after training.Conclusion:Cognitive rehabilitation training under VR technology can better improve cognitive function compared to routine rehabilitation training methods.
