Internationally and in Canada, this classification system only allows only wheelchair users to be eligible to compete.
In contrast, the United States classification system covers wheelchair users and people with vision impairments, with different classes inside these disability types.
[2] Competitors with ambulatory disabilities are able to compete against their able-bodied counterparts as a result of classification.
[6][7] Deaf racquetball has also been organised in the United States,[8] with players being eligible if their hearing loss is 55 db or greater[9] and sorted into divisions based on ability, age and gender.
[15] Racquetball Ireland makes no provisions for intellectual disabilities, wheelchair users, deaf and vision impaired people in their September 2011 rules,[16] and England Squash and Racketball is the same for their rules dated April 2009.
[18] In 1985, the Canadian national championships were integrated, including both non-disabled and disabled athletes in the same event.
[20] In the United States in 1995, a wheelchair user brought suit against a racquetball league after he was unable to compete against top level players with a modified two bounce rule, citing the Americans With Disabilities Act and alleging a violation of Title III of the law.
Additional specific rules include the requirement that only the wheelchair wheels may be used to support the player: hands and feed cannot be used.
[6] There are few restrictions on the type of mobility assisting equipment used by wheelchair competitors except that it cannot interfere with the movement of the other player.
[4] Players in wheelchair classes may choose to compete with roller bars attached to their chair, or have non-marking tires positioned under their footrest.
