Question

which physical exam finding indicates cervical myelopathy?
normal plantar response
reduced biceps reflex
positive lhermitte sign
negative hoffman sign

Explanation:

Cervical myelopathy involves spinal cord compression in the cervical region. A positive Lhermitte sign (electric-shock-like sensations down the spine/limbs with neck flexion) is a classic physical exam finding linked to this condition. A normal plantar response is not indicative, reduced biceps reflex points to root (not cord) issues, and a negative Hoffman sign is a normal finding, not a marker of myelopathy.

Answer:

Positive Lhermitte sign
