Wheelchair racing
T53 describes wheelchair racers with normal arm power but no abdominal or lower spinal muscle activity, which affects how the trunk contributes to propulsion.
These Athletes will have normal arm muscle power with no abdominal and no lower spinal muscle activity. Use different techniques to compensate for lack of abdominal musculature including lying horizontal. In general when acceleration occurs, the trunk rises off the legs due to a lack of abdominal muscles to hold the trunk down; there is no active downward movement of the trunk to assist with propulsion. Usually have to interrupt the pushing cycle to adjust the compensator. Equivalent activity limitation to Athlete with complete spinal cord injury at neurological level T1-7.
