Effects of Virtual Reality (VR) Rehabilitation on Mental Health in SCI Patients: A Randomized Controlled Trial

This randomized controlled trial investigates the effects of virtual reality (VR) rehabilitation on mental health in spinal cord injury (SCI) patients. Seventy-four participants were randomized to 12 weeks of VR-based or traditional rehabilitation, with mental health assessed via the Hospital Anxiety and Depression Scale (HADS) and World Health Organization Quality of Life-BREF (WHOQOL-BREF). The VR group showed significantly greater reductions in HADS scores at 6 weeks (mean change: −4.2 vs. −2.4, p < 0.001) and 12 weeks (mean change: −6.4 vs. −3.9, p < 0.001), with a large effect size (Cohen’s d = 1.21). VR also improved WHOQOL-BREF psychological health scores (+13.5 vs. +6.4, p < 0.001), self-esteem (+7.2 vs. +3.2, p < 0.001), and sleep quality (−5.1 vs. −2.8, p < 0.001). Subgroup analysis indicated greater benefits for younger patients and those with incomplete SCI. VR rehabilitation outperforms traditional methods in enhancing mental health, supporting its integration into comprehensive SCI care.
