Effects of of Nintendo Wii fit balance board virtual reality games as compared with standard of care for improving bilateral coordination among individuals with acute stroke treated at tertiary care institute in South Kerala

Stroke continues to be a major public health challenge in India, particularly in Kerala, where the prevalence and incidence are higher than the national average due to lifestyle and demographic factors(10). A significant proportion of stroke survivors experience long-term motor impairments, including deficits in bilateral coordination, which limit their ability to perform activities of daily living independently. Effective rehabilitation is therefore essential to reduce disability, improve quality of life, and decrease the socioeconomic burden of stroke.

 Conventional physiotherapy remains the standard of care for stroke rehabilitation, focusing on repetitive exercises, balance training, and functional re-education. While effective, these approaches may lack the motivational and engaging elements required to sustain patient adherence, particularly in the acute phase of recovery. Moreover, the resource-intensive nature of traditional rehabilitation can sometimes limit its scalability and accessibility.

 Emerging evidence suggests that virtual reality (VR)-based interventions, such as those provided by the Nintendo Wii Fit Balance Board, can complement and enhance traditional therapy. In this context, virtual reality (VR)-based interventions—such as the Nintendo Wii Fit Balance Board—offer a novel, interactive solution. These systems combine gamified exercises with real-time feedback, encouraging active participation and stimulating bilateral motor activity. The Wii Fit Balance Board, in particular, has shown promise in improving balance, coordination, and motivation among neurological patients, making it a viable adjunct to conventional therapy.

 VR-based rehabilitation creates immersive, interactive, and feedback-driven environments that not only promote motor learning and neuroplasticity but also improve patient motivation and participation. The balance board specifically targets postural control and coordination, which are crucial for bilateral motor recovery. Its affordability and ease of use also make it a viable option for integration into clinical practice in resource-limited settings.

 Despite promising findings from international studies, there is a lack of region-specific research evaluating the effectiveness of Nintendo Wii Fit Balance Board games in stroke rehabilitation in India, particularly in South Kerala, where the stroke burden is notably high. Conducting this study will help generate evidence on whether VR- based rehabilitation provides superior outcomes in improving bilateral coordination compared to the standard of care. The findings may guide clinical decision-making, support cost-effective innovations in therapy, and contribute to developing patient-centered rehabilitation protocols in tertiary care institutes.

 Investigating the effects of Wii Fit Balance Board VR games on bilateral coordination in acute stroke patients is therefore justified. This study could provide evidence for incorporating such technology into early

rehabilitation programs, potentially improving recovery outcomes, increasing patient motivation, and reducing long-term disability.

 This study is grounded in the need to explore cost-effective, engaging, and scalable rehabilitation strategies that can be integrated into standard care. By comparing the effects of Wii Fit Balance Board VR games with traditional physiotherapy, the research aims to generate evidence that could inform nursing protocols, enhance patient outcomes, and support the adoption of technology-driven rehabilitation in resource-limited settings.
