Question

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

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 increased reflex activity (hyperreflexia) in the innervated areas, including the biceps and brachioradialis reflexes. The other options describe lower motor neuron or normal findings, which are not characteristic of this condition.

Answer:

Hyperreflexia in the biceps and brachioradialis
