Segmental zoster paresis (SZP) is a rare complication of varicella zoster infection that occurs due to the spread of the infection from the posterior horn of spinal cord to the anterior horn and the motor nerve root. As recognizing segmental zoster paresis is important in the differential diagnosis of muscle weakness of other origin, information about demographic (gender and age), clinical presentation, diagnosis, treatment, and course about published patients with SZP was extracted from PubMed database. SZP is classified into several categories: paresis of upper extremity, lower limb involvement, diaphragmatic involvement, and abdomen involvement. Published experiences have shown that clinical course and electromyoneurography of paretic muscle are the most important in the diagnosis; physical therapy is the most common therapy in these patients and their prognosis is generally good except diaphragmatic paresis, where there is no significant recovery in most number of patients.
