ABSTRACTObjective: To determine the diagnostic performance of lumbrical-interosseous comparative study.
Methods: A descriptive, transversal and prospective study was conducted on a sample of 60 consecutive patients referred to the laboratory of Clinical Neurophysiology Rehabilitation Hospital Julio Diaz, National Reference Center, with the clinical diagnosis of carpal tunnel syndrome. There is a predominance of females, aged between 35 and 55 years. Evaluation included sensory and motor nerve conduction studies of the median nerve and a comparative study of the median and ulnar nerve with registration in the lumbrical-interosseous muscles.
Results: The nerve conduction study lumbrical-interosseous had a significantly higher detection capability conventionally used to studies, 37 % greater motor studies, 23,9 % to medium palmar and 37,8 % to sensory studies.
Conclusions: The comparative study of lumbrical-interosseous nerve conduction has a capacity of electrophysiological confirmation for carpal tunnel syndrome higher than the conventional median nerve conduction studies: motor study, median palmar mixed study and sensitive study in third finger.
