A Study on the Effectiveness of Home-Based Virtual Reality Rehabilitation Training Content for Elderly Individuals with Degenerative Arthritis

Objective: This study was conducted to investigate the effectiveness of a home-based virtual reality rehabilitation trainingprogram for elderly individuals with degenerative arthritis. The program aimed to assess its impact on muscle strength, joint rangeof motion, and balance. Design: A randomized controlled trial. Methods: A total of 16 adults aged 20 years and older participated in the study. Participants were selected through a randomizationprogram and assigned to a fully immersive virtual reality training program group (n=8) and a traditional rehabilitation trainingprogram group (n = 8). All the subjects were trained three times per week, over four weeks. To compare effects, muscle strength,range of motion(ROM), balance were measured before and after the knee replacement. Results: The based on fully immersive virtual reality training program group had a statistically significant increase in musclestrength(p<.05), ROM(p<.01), and balance (p<.01). And the traditional rehabilitation training program group was experienced a decrease muscle strength(p<.05), ROM(p<.01). The inter-group difference based on the intervention method showed a significantincrease muscle strength(p<.001), ROM(p<.01), and balance(p<.01) in the experimental group (p<.001). Conclusions: It is suggested that training using a home-based virtual reality rehabilitation program may be utilized as an effectiveintervention method for early rehabilitation in patients undergoing total knee arthro-plasty.
