脑卒中患者吞咽障碍康复训练虚拟现实系统的设计与接受度评价

Development and acceptance of a virtual reality system for rehabilitation training of swallowing disorders in stroke patients

目的:设计并开发适合脑卒中吞咽障碍患者的吞咽功能训练系统,在充分体验的基础上调查患者对该系统的接受度。方法:该系统由多学科团队共同设计,针对脑卒中吞咽障碍患者,结合虚拟现实技术(VR),实现形象化、趣味性的知识指导,系统性、针对性的吞咽功能训练,实时性、反馈式的监督与回顾。2022年3—5月采用便利抽样法选取首都医科大学附属北京朝阳医院的39例脑卒中吞咽障碍患者,在充分体验该系统的基础上从感知有用性、感知易用性、感知易学性、感知适用性、感知安全性、感知满意度及使用意向7个维度对该系统进行评价。结果:39例脑卒中吞咽障碍患者康复训练系统的接受度评价得分162(147,170)分;不同文化程度、工作类型、每天使用智能手机累计时间、吞咽训练的学习愿望,对VR设备或技术是否了解、是否认为吞咽训练重要的患者康复训练系统的接受度评价得分比较,差异具有统计学意义(P<0.05)。结论:本系统得益于VR的可视化效果以及良好的沉浸感,相较于传统方式,增加了康复训练过程的趣味性、沉浸感、反馈性,患者对该系统的接受度较高,可推广使用。

Objective To design and develop a swallowing function training system suitable for stroke patients with swallowing disorders,and investigate patients'acceptance of the system based on sufficient experience.Methods This system was jointly designed by a multidisciplinary team,targeting stroke patients with swallowing disorders.By combining virtual reality(VR)technology,it achieved visual and interesting knowledge guidance,systematic and targeted swallowing function training,and real-time,feedback based on supervision and review.From March to May 2022,convenience sampling was used to select 39 stroke patients with swallowing disorders from Beijing Chaoyang Hospital affiliated with Capital Medical University.On the basis of fully experiencing the system,the system was evaluated from seven dimensions,including perceived usefulness,perceived ease of use,perceived ease of learning,perceived applicability,perceived security,perceived satisfaction,and intention to use.Results The acceptance evaluation score of the rehabilitation training system for 39 stroke patients with swallowing disorders was 162(147,170).There were statistically significant differences in the acceptance evaluation scores of the rehabilitation training system for patients with different levels of education,job types,cumulative time spent using smartphones every day,and willingness to learn swallowing training,whether they understood VR devices or technologies,and whether they considered swallowing training important(P<0.05).Conclusions This system benefits from the visualization effect and a good sense of immersion of VR technology.Compared to traditional methods,it increases the fun,immersion,and feedback of the rehabilitation training process,and patients have a high acceptance of the system,which can be promoted and used.
