The impact of an ABI is often both sudden and devastating, and the effects can be physical, emotional, and cognitive. It can shatter families and leave survivors in desperate need of practical support. As an often ‘unseen’ and misdiagnosed condition, that frequently presents challenging behaviour and social difficulties, survivors of ABIs and their families are often isolated and socially excluded. Walking tennis is a slower version of the game and is designed for exercising in a relaxed, supportive and friendly environment. To play the game participants use smaller courts, nets, rackets and lower bouncing balls.
