Peripheral neuropathy in the hands of diabetic patients with lower extremity amputations.
One hundred unilateral ambulatory lower extremity amputees underwent sensibility testing of their remaining foot and right hands to determine if the magnitude of peripheral neuropathy present in the feet of patients with diabetes was of greater magnitude than that in their hands. Testing was performed with a series of Semmes-Weinstein monofilaments. Ninety-one of the subjects were male, and 9 were female. Sixty-five were diabetic, 40 required insulin. The magnitude of peripheral neuropathy was compared between the hands and feet of patients with and without diabetes, and between insulin-dependent and non-insulin-dependent diabetics. There was a slight trend to a more severe degree of insensitivity in the feet as compared with the hands in each of the individual groups. There was no statistically significant difference when comparing hand and foot sensibility in any of the comparison groupings. The quantitative amount of peripheral neuropathy appears to affect the hands and feet of diabetics in a similar "stocking-glove" fashion. The results of this screening gives further support to the concept of prophylactic foot care programs in diabetics with peripheral neuropathy to decrease the risk for the development of foot ulcers, which are often the precursor of eventual lower extremity amputation.
