Problem

The diabetic foot is a chronic complication of diabetes mellitus, characterized by infection, ulceration, or destruction of deep tissues, associated with neurological disorders in various degrees of peripheral vascular disease of the lower limbs(Jin S,2014). Diabetic foot ulceration (DFU) results in the high risk of lower extremity amputation due to the damage of both macro- and micro blood vessels (M.S.Pinzur,2005). The foot ulcers was one of the most serious complications in diabetic patients, which incidence was about 15%-25% (Barbosa AP,2001). What’s more, the foot ulcers was always nonunion because of the lower limb ischemia (Shibuya N,2013). Hence, improving the blood circulation of feet is very important for patients. Peripheral arterial disease was the main reason which lead to lower limb ischemia (Gershater MA,2009). And exercise therapy was the basic treatment of peripheral arterial disease (Degischer S,2002). But the treatment guidelines recommend that braking and decompressing of foot was needed in patients with diabetic foot ulcers (Snyder RJ,2014), that the exercise of the foot and leg received a lot of restrictions. The main problems faced by diabetic foot ulcers patients are: 1) Prolonged bed rest can increase the risk of venous thrombosis. 2) Foot ulcers can’t be healed or delayed healing. 3) Diabetic foot ulcers are easy to recur. Therefore, an appropriate training method is needed for diabetic patients with foot ulcers.
