Clinical Research On Pulmonary Function Rehabilitation Of Patients With Spinal Cord Injury Based On Virtual Reality Technology Pulmonary Rehabilitation Training

Objective:The aim of this study is to observe the effect of pulmonary rehabilitation training based on Virtual Reality（VR）technology on the pulmonary function of patients with cervicothoracic Spinal Cord Injury（SCI）,and to compare it with traditional pulmonary rehabilitation training to clarify the effect of rehabilitation treatment.It provides a new idea for the research of individual training and the formulation of individualized pulmonary rehabilitation treatment plan for SCI patients.Methods:1.A total of 40 patients with cervicothoracic SCI admitted to the Department of Rehabilitation Medicine of the First Affiliated Hospital of Nanchang University from June 2022 to January 2023 were selected and divided into control group（n=20）and observation group（n=20）according to the random number table method.2.On the basis of conventional drug therapy,conventional physical therapy,respiratory muscle training and phrenic nerve electrical stimulation,the control group received conventional pulmonary rehabilitation training,and the observation group received pulmonary rehabilitation training based on VR technology.Both groups were trained for 4 weeks.The gender,age,course of disease,BMI,ASIA classification and injury site of all patients were recorded.The Maximum Inspiratory Pressure（MIP）and Peak Inspiratory Flow（PIF）values of the control group and the observation group before and after training were recorded to evaluate the inspiratory muscle function of the patients.Forced Vital Capacity（FVC）,Forced Expiratory Volume in 1 Second（FEV1）,ratio of FEV1 to FVC（FEV1/FVC）index,Peak Expiratory Flow（PEF）to assess patients’ lung function.Results:1.Comparison of general data between the two groupsA total of 40 patients were selected in this study.The experimental process was smooth,and no one asked to withdraw in advance.The general data（The gender,age,course of disease,BMI,ASIA classification and injury site）of the control group and the observation group were collected before training.2.Comparison of lung function between the two groups before and after trainingBefore training,there were no statistically significant differences in FVC,FEV1,FEV1/FVC and PEF between the two groups（P > 0.05）.After 4 weeks of training,FVC（2.27±0.43 L,2.75±0.54L）,FEV1（1.83±0.36 L,2.37±0.47L）,FEV1/FVC（80.87± 6.60%,86.40± 6.07%）and PEF（3.91±1.13L/s,5.09±0.88L/s）in the observation group control group were significantly higher than those before training,and the observation group was better than the control group,the difference was statistically significant（P < 0.05）.3.Comparison of inspiratory muscle function between the two groups before and after trainingBefore training,there was no significant difference in MIP and PIF between the two groups（P > 0.05）.After 4 weeks of training,the MIP（90.38±9.86 cm H₂O,100.70±10.92 cm H₂O）and PIF（4.42±0.81L/s,5.27±1.07L/s）of the observation group control group were significantly higher than those before training（P < 0.05）,and the observation group was better than the control group.The difference was statistically significant（P < 0.05）.Conclusion:In this study,we used pulmonary rehabilitation training based on VR technology to perform aerobic exercise training for patients with cervicothoracic SCI.After 4weeks of rehabilitation training,the observation group had significant improvements in MIP,PIF,FVC,FEV1,FEV1/FVC,and PEF compared with the control group.On the basis of routine rehabilitation training,pulmonary rehabilitation training based on VR technology can effectively improve the pulmonary function of patients with cervicothoracic spinal cord injury.Pulmonary rehabilitation training based on VR has the characteristics of strong immersion,high interest and high patient compliance,and its effect is better than that of traditional pulmonary rehabilitation training,which is worthy of clinical promotion.
