Walking assisting device for stroke patient

Abstract

The invention discloses a walking assisting device for a stroke patient, which comprises a machine body group, a thigh fixing module, a connecting module, a shank fixing module, an ankle joint damping module and a road condition feedback module, the thigh assisting module is mounted on the inner side of the machine body group, and the thigh assisting module is connected with the shank fixing module through the connecting module; the road condition feedback module is installed at the front end of the machine body set. According to the walking assisting device for the stroke patient, the patient can be helped to keep hip bending, knee bending and ankle bending angles of normal gaits in the walking process, walking of the patient and correction of hemiplegic gaits are facilitated, impact of the patient in the walking process is reduced, strephenopodia symptoms caused by stroke are prevented or corrected, and the walking assisting device is suitable for popularization and application. Meanwhile, the gradient condition of the road surface on the walking route of the patient can be detected in real time, real-time adjustment of hip joints, knee joints and ankle joints of the patient can be achieved according to the road surface condition, and the patient can walk on the road surfaces with different gradients and environments conveniently.

Description

technical field [0001] The invention relates to the field of medical aids, in particular to a walking aid for stroke patients. Background technique [0002] Hemiplegia is one of the common sequelae of cerebral apoplexy. Due to the injury of the high-level center, the patient loses control of the low-level center, and is prone to sensory loss, movement disorder, loss of coordination between muscle groups, and loss of the ability to maintain normal posture control. Clinical manifestations include The weight-bearing capacity and stability of the patient's limbs are decreased, and the center of gravity of the body is shifted to the healthy side, which affects the maintenance of balance and the ability to walk. The main reasons for the hemiplegic gait are: the patient wakes up early and ignores the placement of the good limbs, coupled with the lack of standardized rehabilitation training in the early morning, which leads to the spasm pattern of the extensor muscles of the lower l...

AI Technical Summary

Problems solved by technology

The main reasons for the hemiplegia gait are: the patient gets up early and ignores the placement of good limbs, and lacks early morning standardized rehabilitation training, which leads to the spasm pattern of the extensor muscles of the lower limbs on the affected side, which affects the flexion and extension of the knee joint. This situation continues. Aggravated, resulting in disuse atrophy of the ankle dorsi extensors and knee flexors; the patient excessively raised the affected leg in order to bend the knee when walking, and at the same time caused gastrocnemius muscle spasm, plantarflexion and varus of the foot, resulting in abnormal gait and poor walking ability. decline

In addition, the decline of balance function in stroke patients with hemiplegia is mainly manifested in excessive lateral movement of the body and pelvic rotation, small range of vertical movement and asymmetry of body movement, deviation of the center of gravity of the body, and increased swing coefficient of the center of gravity. As a result, the balance ability is reduced, which further affects the patient's walking ability

[0003] During the walking process, due to high muscle tension, the patient will have difficulty in flexing the hip and knee, and often accompanied by foot inversion, resulting in difficulty in walking and a hemiplegic gait. The existing walking aids can only help the patient Performing walking movements or providing support during the patient's walking process cannot help the patient correct the hemiplegic gait, and the patient encounters complex and diverse environments during the walking process, and often encounters sloped road surfaces. When the patient walks On a sloped road, the bending angles of the hip and knee joints are different from those when walking on a flat road. The existing walking device cannot be adjusted in real time according to the road conditions, which may easily cause the patient to fall. Therefore, We propose a walking assist device for stroke patients
