Abstract
Alternating positive and negative pressure treatments are of definite clinical value in the treatment of peripheral circulatory diseases.1 Periodic skin temperature readings indicate that the clinical improvement is accompanied by increased circulation. However, the absence of significant elevations of skin temperatures following individual treatments does not substantiate the belief that clinical improvement is due to increased circulation. More consistent and higher elevation in skin temperatures is produced by vasodilatation as a result of local heat or reflex heat. Still these measures are less effective in producing clinical improvement than is seen with pressure treatments. Landis2 found that 45 C. heat to the arms produces maximum reflex vasodilatation of peripheral vessels in the legs. It is evident that pressure treatments alone do not produce maximum vasodilatation. Combining reflex heat and pressure treatments, our routine procedure gives higher peripheral temperature readings than either measure alone, as shown in the accompanying
