The body surface temperature of 41 patients suffering coldness, numbness or pain in their feet was examined using thermography. Thermographic results were analyzed quantitatively by calculating a recovery ratio as: Recovery ratio =[Total counts of thermography (Pixels) over temperature (T) after cold loading] ÷ [Initial counts over T before cold loading] x 100(%). Three different baseline temperatures, 26℃. 27℃ and 28℃, were used in processing the thermographic results into pictures. The recovery ratio was susceptible to temperature, and we recommend a baseline temperature limitation of 27℃ for clinical study. A bi-modal distribution of recovery ratio was observed in 18 patients with diabetes mellitus. One group (6 subjects) had high recovery ratio between 80%-100%, and another group (10 subjects) had a low recovery ratio between 0%-19%. The results of thermography were also influenced by weather. To reduce the effect of outside temperature, we used pre-loading with hot water at 36℃ for 5 min (hot loading). A large difference in recovery ratio between presence and absence of hot loading was observed in 6 of the 30 subjects. The difference was over-estimated in more than 20% of recovery ratio without hot loading as compared with hot loading in these 6 subjects. The effect of drugs on peripheral circulation, such as beraprost sodium and sarpogrelate hydrochloride, was clear and quantified using thermography under these conditions of hot loading.
