Question

which signs indicate cervical spinal cord compression in older adults? gait instability, positive upper motor signs unilateral arm pain, sensory loss bilateral leg pain, relieved by sitting acute neck pain, no neurological deficits

Explanation:

Cervical spinal cord compression in older adults typically presents with upper motor neuron dysfunction and issues related to spinal cord involvement. Gait instability arises from impaired spinal cord control of lower extremity movement, and positive upper motor signs (like hyperreflexia, clonus) are classic for spinal cord compression. Unilateral arm pain/sensory loss is more typical of radiculopathy, bilateral leg pain relieved by sitting is spinal stenosis (lumbar often), and acute neck pain without deficits is usually musculoskeletal.

Answer:

A. Gait instability, positive upper motor signs
