title: Pre- and postoperative electromyographic evaluations in the carpal tunnel syndrome.
abstract: Twenty-five cases of carpal tunnel syndrome in 20 patients were evaluated preoperatively and postoperatively by electromyography. Clinical improvement resulted in all cases following decompression of the median nerve, and only in a few instances did mild symptoms persist. Distal motor conduction time im proved postoperatively in 24 cases studied, 19 of which returned to normal range. Most of the obvious improvement occurred within the first 3 months and further improvement could be observed as late as 36 months. Although no definite correlation could be established between the preoperative severity of the carpal tunnel syndrome and the postoperative clinical and electrical im provement, there was a definite evidence of better recovery in the younger age group. There was a greater range of improvement and a return closer to normal postoperatively in cases with severe preoperative distal latency. All cases ex amined after 24 months had reached normal values.
