ABSTRACTThe carpal tunnel syndrome (CTS) is the most common neuropathy of the arm. Since there are many patients with this syndrome, it was of great interest to perform electrodiagnostic studies to establish the adequate diagnosis of this pathology, to the adequate treatment and to facilitate a better prognosis in these patients. The sensitivity and specificity of different electrodiagnostic techniques was evaluated in 46 patients, 59 hands; 44 female and 2 male with CTS without neuropathy, with a range of age from 19 to 69 years old, mean 46 years; 23 controls 46 hands, without pathology from 22 to 56 years old, mean 30 years. Diagnosis showed 32 patients, 32 hands, with CTS of right hand, 1 left, 13 both sides 26 hands, 1 patient, two hands with sensitive alterations, 3 patients, 3 hands with motor alterations, 10 patients 15 hands, with pain, 22 patients, 24 hands, with sensitive alterations and pain and 10 patients 15 hands, with sensitive and motor alterations and pain; 30% mild, 60% moderate, 8% severe and 2% without alterations; 52% with latency affectation to the stimulation of the wrist with active electrode in index finger, 39% in the third finger, 34% in fourth finger, motor velocity conduction (MVC), from palm to index finger 50%, third finger 47%, wrist 30%. Bactriam in 70%; MVC 37%; EMG with denervation data 11%. Our results show that it is important to perform in CTS patients several motor and sensitive neuroconduction techniques to establish a more precise diagnosis that confirms clinical diagnosis.
