"[3] The International Paralympic Committee defined this classification on their website in July 2016 as, "Coordination impairments (hypertonia, ataxia and athetosis)".
[8][10] While CP2, CP3 and CP6 have similar issues with Athetoid or Ataxic, CP6 competitors have "flight" while they are ambulant in that it is possible for both feet to not be touching the ground while walking.

All competitors needed to be internationally classified with their classification status confirmed prior to the Games, with exceptions to this policy being dealt with on a case-by-case basis.
For sportspeople with physical or intellectual disabilities going through classification or reclassification in Rio, their in-competition observation event is their first appearance in competition at the Games.
