Inching method in compression neuropathy of the sural nerve distal to the ankle.

We present the case of a 29-year-old electric engineer with compression neuropathy of the left sural nerve due to occupational boots. Routine nerve conduction study of the sural nerve was normal. However, the sensory nerve action potential was not detected more than 3 cm distal to the lateral malleolus, although it returned to normal values after three years. Inching method of the sural nerve may be necessary for detecting compression sural neuropathy distal to the ankle.
