Lung Function and Health Parameters in Children With and Without Visual Impairment: A Study Protocol for a Two-Phase Study of Comparative Assessment and Randomized Controlled Yoga Intervention

Background Lung function, a key indicator of physical fitness, is underexplored in children with visual impairment (VI) compared to sighted peers. Although physical activity is known to enhance respiratory function and psychological well-being, children with VI face multiple barriers to participation. This study aims to assess lung function and other health parameters in children with and without VI and to evaluate the effectiveness of yoga in improving these outcomes. Methodology The study will be conducted in two phases. Phase one involves a cross-sectional comparative assessment of lung function, autonomic function, muscular performance, postural alignment, and psychological health in children aged 11-18 years with and without VI. Phase two is a randomized controlled trial evaluating the impact of a 12-week yoga intervention on these outcomes in children with VI. Results The study is expected to generate comprehensive data on physical, physiological, and psychological health parameters in children with and without visual impairment. It will also evaluate the potential of a 12-week yoga intervention to improve these outcomes in visually impaired children. Conclusions This study will provide evidence on health disparities associated with VI in children and assess the role of yoga as a holistic intervention to enhance their overall well-being.
