Effects of an Immersive Virtual Reality-Based Exercise-Rest on Mobilization in Knee Surgery Patients: A Single-Blind, Randomized Controlled Trial

Purpose This study aimed to evaluate the impact of immersive virtual reality (IVR) interventions on enhancing mobilization in patients undergoing total knee arthroplasty. Design A randomized, single-blinded, two-arm, parallel-group controlled trial. Methods A randomized controlled trial was conducted on 30 patients who underwent total knee arthroplasty for the first time. Participants were divided into two groups: the intervention and control groups. The primary outcome, mobilization distance, was measured at the first postoperative mobilization using validated scales. Before mobilization, patients in the intervention group experienced a simulated walk through a tranquil forest accompanied by birdsong and meditation music via IVR goggles. Results All surgeries were performed by the same surgeon, and postoperative medical care was standardized across both groups. The intervention group demonstrated significantly greater mobilization distances and shorter initial walking times than the control group. Moreover, patients in the intervention group reported reduced postmobilization pain and expressed high satisfaction with the IVR experience. Conclusions The findings indicate that patients who experienced IVR intervention exhibited reduced postmobilization pain, increased mobilization distance, and higher satisfaction. This innovative technique has the potential to serve as a practical solution to enhance clinical improvement in various healthcare settings. Clinical Implications This study demonstrated the effectiveness of IVR-assisted mobilization in enhancing walking distance among patients undergoing knee surgery. The use of IVR presents an innovative and engaging approach to support postoperative mobilization in this patient population. Further research in this area may contribute to the development of more comprehensive and effective IVR interventions.
