Review Question - QID 218903

A 32-year-old male presents with a four-month history of loss of sensation along the median nerve distribution of his right hand. He states he wakes up once or twice a night and needs to shake out his hand due to the feeling of pins and needles. He has a positive Phalen test and undergoes a nerve conduction study. The report states his sensory nerve action potentials (SNAPs) display increased latency with decreased nerve conduction velocity across his wrist compared to the unaffected, contralateral side. The SNAPs amplitudes remain equivalent bilaterally. He undergoes a corticosteroid injection to his carpal tunnel, which provides relief for 2-3 weeks with regression of symptoms thereafter. Given these findings, how should the patient be counseled regarding his nerve conduction studies?
