Stroke foot swelling refers to the swelling of the foot caused by the poor venous return or lymphatic return in the lower limbs of stroke patients who have been walking or standing for a long time, thus causing some water in the blood vessels to seep into the tissue interstices. For stroke foot swelling, patients should firstly do proper exercise, and secondly, during exercise, they should focus on maintaining the temperature of the limb with poor activity, as high temperature can promote blood circulation. At present, air pressure wave is mostly used to treat swollen feet in stroke, which can promote the patient’s blood circulation to prevent the formation of venous thrombosis.
