Herpes zoster is caused by reactivation of the varicella zoster virus and characterized by segmental, painful vesicles along the dermatome. Frequently it causes neurological manifestation such as neuropathic pain, but motor neuropathy is uncommon, of which the reported incidence is between 0.5-31%\ Some studies using objective methods such as electromyography and the motor nerve conduction velocity test revealed that subclinical motor nerve involvement was more than just clinical motor function weakness. Motor neuropathy caused by herpes zoster can occur in both visceral and somatic (cranial and peripheral) nerves. The functional abnormalities of motor neuropathy observed in our patient were attributable to involvement of the ipsilateral C5-6 level by herpes zoster. The patient received 6 months of physical therapy for her motor deficit, and clinically improved.
