Muscle wasting after prolonged hypoglycaemic coma: case report with electrophysiological data.

A case of distal muscle wasting associated with hypoglycaemia is described. Motor and sensory conduction studies are reported that provide little evidence of a hypoglycaemic peripheral neuropathy. Damage to anterior horn cells or motor roots appears to be a more likely explanation for the amyotrophy. Recovery occurred clinically with evidence of reinnervation by axonal collateral sprouting.
