Question

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

Explanation:

Cervical myelopathy involves spinal cord compression in the cervical region. A positive Lhermitte sign (electric-shock sensations down the spine/limbs with neck flexion) is a classic exam finding linked to this condition. A negative Hoffman sign, reduced biceps reflex, and normal plantar response are not indicative of cervical myelopathy; a positive Hoffman sign or abnormal (upgoing) plantar response would be more associated, while reduced reflexes point to root issues, not myelopathy.

Answer:

Positive Lhermitte sign
