Development of multimodal ankle joint movement device / 医疗卫生装备

ABSTRACT

Plantaris bend malformation of ankle joint,a serious epiphenomenon will occurs when patients lie on bed for a long time.A new type of ankle joint movement device is studied.Powered by electric motor with giant torque and super low velocity and controlled by timing controlling circuit,this device enable the ankle joint a 20?～ 30?back stretch and 40?～ 50?plantaris bend.Furthermore,it can set different moving angle and time according to individual conditions and can perform slow,continuous and reciprocating motion for different actual need.Patients whose ankle joints are unable or difficult to move actively can benefit from this device in preventing plantaris bend malformation of ankle joint,ankle joint stiffness and muscle atrophy of lower limb.
