Recovery of cold, warmth and heat-pain sensations in skin grafts was studied psychophysically in 22 patients who had had split skin grafts transplanted over muscle fascia 1 to 4 years earlier. A thermal stimulator based on the Peltier principle and controlled by a microprocessor was used to measure the thermal sensitivity of the grafts. Control measurements were obtained from the corresponding opposite side of the body. Cold sensitivity was present in 14 grafts (from 1-4 years old). However, with one exception, the threshold for cold sensation remained higher than normal in all patients. Warmth sensitivity was present in 6 grafts (from 1-4 years) which were all also sensitive to cold. Heat-pain sensitivity was present in 8 grafts. If the warmth and heat-pain sensibility had recovered, the sensation threshold was closer to the normal value than that for cold. In 7 grafts (from 1-3 years) no recovery was obtained.
对22例在1至4年前于肌肉筋膜上移植了中厚皮片的患者，采用心理物理学方法研究了移植皮片中冷觉、温觉和热痛觉的恢复情况。使用基于珀耳帖原理并由微处理器控制的热刺激器来测量移植皮片的热敏感性。对照测量取自身体相应的对侧。14块移植皮片（移植时间为1至4年）存在冷觉敏感性。然而，除1例例外，所有患者的冷觉阈值均高于正常。6块移植皮片（移植时间为1至4年）存在温觉敏感性，这些皮片对冷也敏感。8块移植皮片存在热痛觉敏感性。如果温觉和热痛觉敏感性已恢复，其感觉阈值比冷觉更接近正常值。7块移植皮片（移植时间为1至3年）未出现恢复情况。
