Abstract: SUMMARY -Eighty untreated patients suspected to have leprosy were submitted to neuro¬ physiological examination and later compared with the clinical diagnosis. Among the patients who had leprosy confirmed, 98% had EMG abnormalities.Motor and sensory amplitude reduction was the earliest and the most frequent abnormality. Low conduction velocity of the ulnar nerve across the elbow was present in over 55% ot the patients.A «mosaic» peripheral polyneuropathy was the most characteristic finding, and seems to be hel… Show more

“…These abnormalities were asymmetric, according to the nature of the disease. These findings are in agreement with the literature, which points to the peroneal nerve as the most frequently compromised one, after the ulnar nerve [24][25][26][27] .…”

“…The electromyographic examination allows the detection of precocious alterations in leprosy, even when clinical examination gives no evidence of it 18 . Electromyographic alterations can be detected in up to 98% of the cases when several muscles are studied 25,28 . We did not find electromyographic potentials compatible with primary muscle involvement (myopathic), as it had rarely been described 18,[29][30][31] .…”

“…The electroneuromyographic pattern of leprosy neuropathy described in the literature is the impairment of conduction of nerve impulse 28 and decreased amplitude of sensory-motor potentials 29 . Tzourio et al 30 reported the absence of correlation between neurological symptoms and electroneurographic studies in leprosy patients.…”

“…In this connection, nerve conduction studies (NCS) are a sensitive method for the investigation of PNL 13,28,30 (C). There is prominence of demyelinating neuropathy of the ulnar nerve at the elbow in 55.0% of the cases 34,36 (C). All these studies emphasize the asymmetric and multifocal impairments.…”
