Question

which reflex abnormality is commonly observed in patients with cervical myelopathy?
hyporeflexia in the patellar reflex
hyperreflexia in the biceps and brachioradialis
absent achilles reflex
normal reflex responses throughout

Explanation:

Cervical myelopathy involves compression of the spinal cord in the cervical region, which disrupts upper motor neuron pathways. Upper motor neuron lesions typically cause hyperreflexia (increased reflexes) in the muscles innervated by the affected spinal segments. The biceps and brachioradialis reflexes are controlled by cervical spinal levels (C5-C6), which are directly impacted in cervical myelopathy. Hyporeflexia or absent reflexes are associated with lower motor neuron issues, and normal reflexes are not consistent with this condition.

Answer:

Hyperreflexia in the biceps and brachioradialis
