Abstract

Introduction: With increasing life expectancy, the elderly population is at higher risk for cardiorespiratory decline. Exercise is known to reduce this decline, but adherence to exercise programs can be low. Virtual reality (VR) exergaming offers an engaging alternative, potentially increasing motivation while providing similar benefits. This study aimed to evaluate the effectiveness of VR exergaming in improving cardiorespiratory function in elderly individuals. Methods: A randomized controlled trial was conducted with 40 elderly participants (VR exergaming, n=24; conventional aerobic exercise, n=16). Both groups exercised three times per week for six weeks. The VR group used Ring Fit Adventure on the Nintendo Switch, while the control group performed structured aerobic exercises. Cardiorespiratory parameters—heart rate (HR), respiratory rate (RR), blood pressure (BP), predicted maximal oxygen uptake (VO₂ max) from the 6-minute walking test (6MWT), peak expiratory flow rate (PEFR), and peak cough flow rate (PCFR)—were assessed before and after the intervention. Results: Significant improvements were observed in VO₂ max, RR, BP, PEFR, and PCFR in both groups, though HR did not change significantly. Despite baseline differences in VO₂ max, overall improvements were comparable between the two groups. Conclusion: VR exergaming was as effective as conventional exercise in improving cardiorespiratory function in older adults and offers an engaging and enjoyable alternative.

Abstract

Background: More than 60% of stroke patients have chronic neurological impairments that impair hand strength and cognitive function, lowering their quality of life. While virtual reality (VR) exergames have been extensively researched as adjuvant therapies, evidence of their simultaneous effects on motor and cognitive skills is scarce. This study aimed to evaluate the impact of VR exergames on handgrip strength and cognitive function in post-stroke patients. Methods: The study used a randomized controlled trial design with 60 subacute post-stroke patients who were randomly assigned to either the control group, which received conventional care (occupational therapy and physiotherapy), or the intervention group (conventional care plus VR exergame therapy) for eight weeks. This study included first-time stroke patients with onset ≥1 month, mild to moderate hemiparesis (MMT ≥ 3), and hemodynamic stability. Participants with significant spasticity (MAS > 3), aphasia, or uncontrolled comorbidities were excluded. Before, during, and after the intervention, handgrip strength and cognitive function were tested using the Indonesian version of the Montreal Cognitive Assessment (MoCA-Ina). Results: After 8 weeks of therapy, the intervention group showed a significant increase in handgrip strength (+3.9 points, p-value= 0.040) and MoCA-Ina scores (+5 points, p-value= 0.007) compared to the control group. Conclusion: Integrating VR exergames with conventional rehabilitation significantly improves handgrip strength and cognitive function in post-stroke patients compared to traditional therapy alone.
