A T11 athlete may be entirely without sight, or be able to perceive light, but have no ability to see the shape of a hand at any distance.
Athletes in this category have a variety of visual impairments, but can typically recognize contours from a distance of 2 to 6 metres.
These athletes do not have the capacity to remain still and they show involuntary movements with all four limbs affected.
Final The T44 category is for athletes who have a single below knee amputation or who can walk with moderately reduced function in one or both legs.
The T46 category is for athletes who have a single above or below elbow amputation or similar disability, with normal function in both legs.
Pushing power comes from elbow extensions, and appears close to normal except for use of modified gloves to compensate for grip.
