The Paralympic Games are an
international sports competition
for athletes with disabilities.
They are held in the same year and city as
the Olympic Games. Vancouver was named

For most paralympic sports, the
athletes are grouped into classes
according to their balance,
coordination, range of motion, and
skills required for the sport.
