In 2019 Sense, the National Deafblind and Rubella Association, and the ukactive Research Institute partnered to support the physical activity opportunities of children with complex disabilities. This is a two stage research project. Building upon the public inquiry conducted by Sense in 2015, the first phase of research looked at understanding the complex needs that families with disabled children are facing, focusing on their challenges, barriers and motivations to engaging their children in physical activity. This was conducted through a national consultation of a survey and focus groups, and will inform the development of Sense’s multi-sport delivery programme, which the ukactive Research Institute will be measuring, monitoring and evaluating. The aim of this measurement and evaluation will be to measure the health and wellbeing of those taking part in the activities, linking where feasible and appropriate, to national data from Sport England’s outcomes framework, and other relevant measures.
