基于虚拟现实的六字诀训练对慢性阻塞性肺疾病稳定期的疗效观察OA

Objective To investigate the clinical efficacy of using virtual reality technology(VR)for Six Word Formula breathing training in the treatment of patients with stable chronic obstructive pulmonary disease(COPD).Methods A total of 88 hospitalized and outpatient patients diagnosed with stable COPD by Western medicine and pulmonary distension by traditional Chinese medicine(TCM)admitted to the Third Affiliated Hospital of Zhejiang Chinese Medical University from July 2022 to May 2023 were included.They were divided into the conventional group(n=44)and the VR group(n=44)according to the simple random sampling method.Both groups of patients were treated with conventional therapy.The conventional group was given regular Six Word Formula breathing training,while the VR group was given Six Word Formula breathing training based on VR.The changes in first second forced expiratory volume(FEV1)and one second rate(FEV1/FVC),6-minute walking test(6MWT),and COPD assessment test(CAT score)between two groups were observed.Results After training,the FEV1,FEV1/FVC,6MWT,and CAT scores of the VR group were all higher than those of the conventional group,with statistically significant differences(P<0.05).In addition,Pearson correlation analysis showed a negative correlation(r=-0.509,P<0.05)between the 6MWT minimum clinically significant difference(6MWT MCID)and the CAT minimum clinically significant difference(CAT MCID)in the VR group.Conclusion VR based Six Word Formula breathing training can effectively assist COPD patients in pulmonary rehabilitation and may improve the practicability of six-character breathing training and patient compliance.
