Which condition is characterized by a 17% prevalence of atlantoaxial instability?

The condition characterized by a 17% prevalence of atlantoaxial instability is Down syndrome. Individuals with Down syndrome often have congenital anomalies, including ligamentous laxity and atlantoaxial instability, which involves instability at the junction of the first two cervical vertebrae (the atlas and axis). This instability can lead to a risk of spinal cord compression, which can result in neurological issues.

Understanding these specific conditions and their associated risks helps inclusive fitness trainers create safe and effective exercise programs for individuals with such medical considerations. In this context, recognizing the prevalence of atlantoaxial instability in Down syndrome is crucial for developing appropriate interventions and accommodating the unique needs of individuals with this condition.
