Effectiveness of Immersive Virtual Reality Combined With Occupational Therapy in Reducing Fall Risk and Frailty Among Older Adults

Population aging is a growing global phenomenon that poses significant challenges to healthcare systems, particularly in preventing falls and managing frailty among older adults. Falls remain a leading cause of morbidity and mortality in this population, affecting approximately one-third of individuals over 65 each year. At the same time, frailty syndrome (FS)-a clinical condition marked by progressive decline in physical and cognitive function-significantly increases the risk of falls, disability, and dependency. Pre-frailty, an intermediate and reversible stage, offers a key opportunity for preventive interventions. Scientific evidence supports the effectiveness of interdisciplinary approaches to address frailty and fall prevention. In this context, occupational therapy plays a central role by promoting functional autonomy through meaningful activities. However, traditional approaches may be limited in individuals with low motivation or mild cognitive impairment. Therefore, integrating innovative technologies such as immersive virtual reality (IVR) emerges as a promising therapeutic strategy. IVR enables users to interact with simulated three-dimensional environments, enhancing cognitive stimulation, motor training, and treatment adherence. Modern devices like the Meta Quest 3 headsets provide accessible, safe, and adaptable immersive experiences, with reported benefits in balance, gait, attention, and motivation. Nonetheless, no studies to date have specifically evaluated the effectiveness of this technology when combined with conventional occupational therapy to reduce fall risk and frailty in older adults. This project proposes a pilot randomized controlled trial (RCT), lasting 5 months, using a single-blind, parallel-group design. It will be conducted at the Bouco Madrid Ferraz Residential Center (Madrid, Spain), following CONSORT 2010 methodological guidelines. The primary aim is to assess the efficacy of a combined intervention using IVR through Meta Quest 3 headsets and occupational therapy, compared to conventional occupational therapy alone, in reducing fall risk, improving frailty status, enhancing quality of life, and increasing rehabilitation motivation in older adults. The sample will include 30 participants (15 per group), selected based on specific inclusion and exclusion criteria. Participants will be randomly assigned to a control group (CG), receiving standard occupational therapy, or to an experimental group (EG), receiving a combined intervention of occupational therapy and IVR using the Kinesix XR platform, which is designed to enhance balance. The intervention will last 8 weeks, with two one-hour sessions per week. The experimental group will receive 30 minutes of occupational therapy and 30 minutes of IVR per session. Assessments will be conducted at baseline, post-intervention, and at a 3-month follow-up using validated scales to measure fall risk, balance, frailty level, quality of life, and satisfaction. Data will be pseudonymized, statistically analyzed using SPSS, and managed in compliance with the European General Data Protection Regulation (EU 2016/679). The small sample size reflects the exploratory nature of the study, aimed at assessing feasibility, safety, and preliminary outcomes prior to conducting a larger-scale trial. Ultimately, this project aims to provide initial evidence on an innovative intervention for older adults by integrating digital tools with conventional therapeutic approaches. If proven effective, the VIRTO-FRAIL model could lay the groundwork for new strategies in geriatric rehabilitation and fall prevention.
