Which functional sign may be affected by atlantoaxial instability in Down syndrome?

Explanation:
Atlantoaxial instability in Down syndrome often arises from lax ligaments around the upper cervical spine, which can allow C1-C2 to compress the spinal cord. When the cervical cord is affected, motor pathways and proprioceptive transmission that control balance and coordinated movement are disrupted, leading to gait changes. This functional sign reflects how cervical cord involvement translates into real changes in walking, balance, and coordination. Hearing loss and visual changes are not direct manifestations of this instability, and skin lesions are unrelated to cervical spine instability.
