Cerebral Palsy-International Sports and Recreation Association defined this class in January 2005 as, "Quadriplegic (Tetraplegic)-Severe to moderate involvement.
Class 2 athletes (upper or lower) can sometimes ambulate but never run functionally.
Dynamic trunk control is poor as demonstrated by the obligatory use of upper extremities and/or head to assist in returning to the mid-line (upright position).
[4][6][7] When participating in sport, CP2 competitors tend to have low energy expenditure.
[2] 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.
[1][3][7][10] Events that may be on the program for CP2 competitors include the club, discus throw, shot put and javelin.
[7] In track events, they have poor wheelchair control and may only be able to push their chair forwards using one arm.
In field throwing events, CP2 competitors may have poor device release because of spasticity in their hands but still have good upper body rotation.
[7][11][12] Prior to a classification rule change made in 2009, CP2 Lower athletes often compete in T31 for track events.
[14] People with cerebral palsy are eligible to compete in boccia at the Paralympic Games.
[6] Tricycles are often required because their level of CP effects their balance and they are unable to use a standard bicycle.
[22] All CP2 cyclists are required to wear a helmet, with a special color used to designate their class.
[1] Compared to other CP race running classes, CP1 and CP2 have a low economy of movement.
[20] CP2 sports people are eligible to compete in swimming at the Paralympic Games.
[26] People with cerebral palsy are eligible to compete at the elite level in a number of other sports including lawn bowls and archery.
[10] One of the standard means of assessing functional classification is the bench test, which is used in swimming, lawn bowls and wheelchair fencing.
[28][29] As part of the water test, swimmers are often required to demonstrate their swimming technique for all four strokes.
