Quantification of thermal sensory loss in follow up of progress in leprosy

Thermal sensory perception quantitatively was studied in follow up of 10 lesions (4 TT, 3 BT and 1 Indeterminate case) of cases put on poly therapy as per WHO regime, for 6 months. Significant thermal sensory improvements was noticed in 4 lesions after 4 months of therapy. Within 2 months of therapy, 3 cases showed improved perception of heat sensation but 1 showed deterioration. Recovery of sensations did not correspond to other clinical parameters of improvement in all the cases. The utility of quantitative evaluation of thermal sensory perception in follow up of leprosy cases is discussed.
