Description

Ankle rehabilitation auxiliary training device for hemiplegia patients

technical field

The invention relates to the technical field of ankle joint rehabilitation training devices, in particular to an auxiliary device used for the training of ankle joint plantar flexion movement (foot padding) with distal end fixation of hemiplegic patients.

Background technique

Hemiplegia, also known as hemiplegia, refers to the movement disorder of the upper and lower limbs, the facial muscles and the lower part of the tongue muscle on one side. It is a common symptom of acute cerebrovascular disease.

Ankle joint dysfunction is a common complication in stroke patients with hemiplegia, and it is one of the main reasons that affect walking function and quality of life. After stroke patients with hemiplegia, the higher motor functions dominated by the cerebral cortex are inhibited, showing muscle spasm patterns; The flexor spasm pattern caused by the joint movement of the upper limb flexors and the extensor spasm pattern caused by the joint movement of the lower limb extensor muscles are prone to complications such as foot varus and foot drop, which seriously affect the patient's standing and walking. With immobilization for more than 3 weeks, the loose connective tissue around the joint can turn into dense connective tissue, resulting in joint contracture deformation. Due to the occurrence of joint complications in patients, the residual motor function or the recovered function of the affected limb is lost again, which seriously affects the recovery of lower limb motor function. Clinically, ankle function is easily overlooked in the whole course of stroke patients with hemiplegia, but it directly affects the prognosis and rehabilitation of patients. Therefore, it is very important to carry out rehabilitation training of the ankle joint.

The ankle joint is composed of the articular surface of the lower end of the tibia and fibula and the talus trochlear, so it is also known as the talus calf joint. The lower articular surface of the tibia and the medial and lateral ankle articular surfaces jointly form a "冂"-shaped articular socket, which accommodates the talus trochlea (joint head). Because the trochlear joint is wide in front and narrow in the back, when the foot is dorsiflexed, the wider anterior part enters inside the socket to stabilize the joint.

The main source of power relied on during normal walking is the plantar flexion movement of the ankle joint (foot padding) that is distally fixed and proximally raised by the contraction of the triceps calf during walking. The training of this movement is very important to improve the walking ability of hemiplegic patients; hemiplegic patients often do not step their feet alone, and often use abnormal movement patterns to compensate for the movement; in the current walking training of hemiplegic patients, the training of foot-stepping movement is often neglected and often As a result, the improvement of walking ability of hemiplegic patients is hindered; the existing technology also lacks corresponding special equipment.

To sum up, the power of foot pad is the main power source in normal walking, and it is very important for the improvement of walking ability of hemiplegic patients. The defect of the prior art is that the existing ankle joint rehabilitation training device lacks training for the triceps calf padding of the hemiplegic patient, which is not convenient for improving the walking power of the hemiplegic patient, but makes it easier for the hemiplegic patient to form an abnormal walking power pattern. Therefore, the present invention aims to design an ankle joint rehabilitation training device for foot pad training for hemiplegic patients.
