Electro neuro physiological studies in early tuberculoid leprosy.

Electro physiological studies were carried out in early tuberculoid type of leprosy in order to study their utility in detecting nerve damage before the onset of obvious functional deficit. Fifty-three cases showing one mixed nerve thickening in one limb were selected. Nerve conduction studies (both motor and sensory) were done using single blind technique. There was no statistically significant difference between the findings obtained from clinically thickened and non-thickened nerves. There was also no direct relationship between clinical sensory deficit and electro physiological abnormality. Clinical motor power loss was well correlated with electro physiological abnormalities.
