INTRODUCTION: Sensory testing in people affected by Hansen's disease is usually performed on palms and soles only. In Israel, both palmar/plantar and dorsal aspects of limbs are routinely tested.
OBJECTIVES: The aim of this study was to describe the magnitude of dorsal sensory impairment (SI) in limbs and compare the frequency of SI on palms and soles with that on the dorsum of hands and feet.
DESIGN: In a cross-sectional study, limbs of 140 patients registered at The Israel Hansen's Disease Centre during the years 1999-2003 were tested for their sensory status. Both palmar/plantar and dorsal aspects were tested using Semmes-Weinstein monofilaments. SI was defined as not feeling stimuli applied with the 2 g monofilament.
RESULTS: SI was detected on the dorsum in 43% of sites on hands and only in 27% on palms. 64% of sites on dorsum of feet had SI compared to 53% on the soles. SI was detected in up to 18% in hands with no palmar SI, and in 6% of feet with no plantar SI. Furthermore, SI on palms and soles was found to be accompanied by dorsal SI in all hands and in 97% of feet.
CONCLUSION: SI on dorsum of limbs occurs more frequently than SI on palms and soles. Therefore sensory testing should also consider inclusion of the dorsal aspect of hands and feet.
