Abstract
Abstract : Measures of tactual acuity and heat and pain sensitivity were obtained from 20 subjects with unilateral arm amputations. The measures were taken 3 in. above the stump and on a homologous area of the intact arm. Corresponding areas were tested in 20 matched controls. The tactual acuity of the stump was significantly greater than that of the intact limb or of either limb of the controls. For heat and pain sensitivity there was no significant difference between the stump and the intact arm. However, both arms of the amputees were significantly less sensitive to heat and pain than either arm of the controls. The results are related to current theories of cutaneous sensitivity.
