Blood circulation in an injured human foot is involuntarily promoted in a vacuum over-pressure cycle and in synchronism with the human hearts systolic and diastolic pressure pulsations. In a preferred embodiment, the circulation enhancing apparatus comprises an air tight boot contoured to fit the injured human foot, a pressure modulator for providing over-pressure and vacuum pulses to the boot to enhance blood circulation through the injured foot and a control circuit which monitors the hearts systolic and diastolic pressure pulsations and provides electrical control signals to the pressure modulator to assure that the over-pressure and vacuum pulses are cyclic and in synchronism with the hearts systolic and diastolic pressure pulsations.
