Description

Novel multifunctional portable ankle rehabilitation device

Technical Field

The invention relates to equipment for rehabilitation training, in particular to a novel multifunctional portable ankle rehabilitation device.

Background

The long-term braking state of limbs after long-term bed rest or trauma can cause lack of bone load and reduction of muscle contraction, and foot drop, osteoporosis and Deep Venous Thrombosis (DVT) of lower limbs are easy to occur. The foot drop can be caused when a patient lies in bed for 3-8 days after the patient lies in bed for a long time with nerve injury. The incidence of DVT in trauma patients reaches 58% -63%, and the high risk stage of bone loss is 4-6 months after braking, and the bone loss is more serious along with the longer the fixation time of the affected limb.

At present, the active and passive movement of a patient is mainly guided through health promotion and education clinically, the foot drop prevention support such as a T-shaped shoe prevents foot drop and the auxiliary movement of a knee and ankle exerciser performs early limb muscle contraction or joint movement, so that the foot drop, the osteoporosis and the DVT are effectively prevented. The health propaganda has the defects of high requirement on the specialty of nurses and no effect on patients with poor compliance; the drop foot prevention brace has the defects of no DVT and osteoporosis prevention effect; the knee and ankle exerciser has the defects that the knee and ankle exerciser are designed without mechanical stress stimulation, and the gradual loss of the bone mass of a patient cannot be effectively prevented. In addition, the machine is heavy and expensive, is only suitable for being used in hospitals, and is not suitable for patients who lie in bed for a long time and have poor autonomous activities after discharge.
