Because of the risk of injury, Special Olympics Illinois has established a policy. The policy states that any participant with Down Syndrome, involved in any Special Olympics sport/activity, must obtain a x-ray, submit a letter from their physician, and complete the Special Olympics Illinois medical form. The letter must state that the individual does not have atlanto-axial instability prior to participating in the program. All programs in the brochure which require AAI clearance are marked with the AAI symbol. Please contact the SSSRA office for more information.
