[3] The Canadian Paralympic Committee says of sledge hockey, "To participate in IPC competitions and sanctioned events (i.e. Paralympic Winter Games), athletes must have an impairment of permanent nature in the lower part of the body of such a degree that it makes ordinary skating, and consequently ice hockey playing, impossible.
Examples include amputation, spinal cord injury, joint immobility, cerebral palsy and leg shortening of at least 7cm and 'les autres.
[6] Eligible ice hockey players need to have a permanent lower body physical impairment that prevents them from skating normally.
[8] In 2002, for the Winter Paralympics, the Games Classifiers were Bjorn Hedman, Irv Grosfield, Carin Njorne and Michael Riding.
[13] Going forward, disability sport's major classification body, the International Paralympic Committee, is working on improving classification to be more of an evidence-based system as opposed to a performance-based system so as not to punish elite athletes whose performance makes them appear in a higher class alongside competitors who train less.
