Cardiorespiratory Physiotherapy with Virtual Reality Integration: Shaping the Future of Rehabilitation

Abstract Dyspnoea, fatigue, diminished exercise capacity, and a reduced quality of life (QoL) are associated with chronic cardiorespiratory (CR) conditions such as coronary artery disease (CAD), arrhythmias, chronic obstructive pulmonary disease (COPD), pulmonary hypertension (PHT), and post-coronavirus disease (COVID) complications. Conventional rehabilitation approaches, despite their efficacy, are overlooked in India due to challenges such as patient compliance, expense, and accessibility. Virtual Reality (VR) has emerged as a state-of-the-art adjunct to rehabilitation through its immersive, engaging, and adaptable interventions. Ten peer-reviewed publications, published between 2014 and 2025, were retrieved from PubMed, Scopus, Web of Science, and Google Scholar using the phrases "VR," "Physiotherapy," "Intervention," and "Cardiorespiratory conditions" for this scoping review. The included research explored VR applications across various groups affected by COVID-19, COPD, CAD, arrhythmias, and related illnesses. The reported outcomes included exercise tolerance, dyspnoea scores, functional fitness, hemodynamic responses, anxiety, sadness, stress, and patient perceptions. Findings indicate that VR-based interventions significantly enhanced psychological and physical well-being, reducing dyspnoea, improving functional capacity, and eliciting hemodynamic responses equivalent to conventional exercise. VR markedly enhanced patient engagement and compliance, illustrating its capacity to eliminate barriers to recovery. Nonetheless, there are specific disadvantages, including inconsistent QoL outcomes, limited sample sizes, and diverse methodologies. This review concludes that VR has the potential to revolutionise cardiorespiratory rehabilitation (CRR) comprehensively. Future studies should focus on the integration of standardised protocols with telemedicine and VR to increase accessibility and clinical efficacy of CRR.
