Abstract: Objective: Apply Virtual Reality technology in home-based rehabilitation training for patients with spinal cord injury and analyze its effects, to provide references for the rehabilitation of patients with spinal cord injury. Methods: Using the convenience sampling method, patients with spinal cord injury who were discharged from a tertiary grade A hospital in Beijing from May to August 2024 and received home-based rehabilitation were selected as the research subjects and randomly divided into the intervention group (n=20) and the control group (n=20). The control group was trained according to the home-based training program based on evidence; the intervention group received additional application of Virtual Reality technology on the basis of the control group. The trunk muscle function, depression status before and 6 weeks after the intervention, blood pressure, blood oxygen saturation, discomfort symptoms, and adverse events during training were compared between the two groups. Results: One patient in the intervention group dropped out during the intervention. After 6 weeks of intervention, the root mean square of electromyographic signals during maximum voluntary contraction of the erector spinae, rectus abdominis, and external oblique abdominis in the intervention group were higher than those in the control group (P<0.01); the depression scores of the intervention group were lower than those of the control group (P<0.01). During the training period, the blood pressure and blood oxygen saturation values of both groups fluctuated within 10%, and no discomfort symptoms or adverse events occurred during training. Conclusion: The home-based rehabilitation training model for spinal cord injury patients based on Virtual Reality technology can improve the rehabilitation effect of patients and has good safety.
