Intelligent recovery device for lower limb spasm

Abstract

The invention relates to an intelligent recovery device for lower limb spasm. The intelligent recovery device comprises a chassis, a seat, a thigh supporting mechanism, a shank supporting mechanism, a motor driving mechanism, a foot plate fixing mechanism, a mechanical safety position-limit mechanism and a control module. The thigh supporting mechanism comprises a support rod and a T-shaped support, the shank supporting mechanism comprises a front-back translation rod, a left-right translation rod, a lower support rod, a vertical translation rod, an arc support and a bandage, and the motor driving mechanism comprises a front-back translation support, a motor support, a bearing seat and a motor external member. The foot plate fixing mechanism comprises a foot plate, a plurality of bandages, a tilt angle sensor, a foot lateral plate, a torsion sensor and a coupler, the control module comprises three electrode plates, a data acquisition unit, a motor driver and a data analysis unit arranged on a computer, and the data analysis unit comprises a calculation module and a circuit safety position-limit module. The intelligent recovery device enables a patient to participate in recovery control through feedback of electrical signals and joint moment on surfaces of muscles of the patient, increases initiative intervention of the patient, and accordingly promotes rehabilitation efficacy. The intelligent recovery device can be widely applied to recovery of the lower limb spasm.

Description

technical field [0001] The device relates to an intelligent rehabilitation device, in particular to an intelligent rehabilitation device for lower limb spasm. Background technique [0002] Cerebrovascular disease is one of the diseases with the highest mortality and disability rate in my country. During the rehabilitation of stroke patients, spasticity and / or contractures of the muscles around the ankle severely limit their ability to walk and live independently. [0003] The development of spasticity and / or contracture in stroke patients has been attributed to changes in neural reflexes following cerebrovascular disease and associated shortening of muscle / tendon tissue due to persistent hypertonia. The common clinical prevention and treatment method is the passive movement of the joint. The therapist drives the patient's ankle joint to and fro within its range of motion by hand or using a "continuous passive stretching" device, and stretches the muscles around the ankle jo...

AI Technical Summary

Problems solved by technology

However, the limitations of these two methods are also obvious

First of all, the determination of the range of motion of the ankle joint depends on the subjective feeling of the therapist or patient, so the muscles are often not fully stretched under the maximum range of motion of the joint

Secondly, the existing "continuous passive stretching" device lacks real-time feedback of the nerve signals of the relevant muscles during the exercise process, but simply drives the ankle to reciprocate, and the rehabilitation effect is not very obvious
