Grant's interest in the role of sport in the rehabilitation for people with spinal injuries can be linked to the work of Sir Ludwig Guttman, neurologist from Stoke Mandeville Hospital. In 1957, he visited the hospital and observed the role of sport in rehabilitation. In 1958, he played a major role in organising the First Royal North Shore Hospital Games for spinal injury patients. The Games were held at the Gore Hill Oval near the hospital. Grant also played a role in the inclusion of sport in rehabilitation programs at Mt Wilga Rehabilitation Centre. It held annual Sports Days. The Australian Team to the 1960 Rome Paralympics included eight competitors who had been patients at Mt Wilga Rehabilitation Centre and trained by Kevin Betts and Eileen Perrottet.
