Gait phase distinguishing method based on upper-and-lower limb movement information

Abstract

The invention discloses a gait phase distinguishing method based on upper-and-lower limb movement information.The gait phase distinguishing method includes the steps that angle information is received through a neck angle sensor, large arm angle sensors, thigh angle sensors and shank angle sensors; the angles and the angular speeds of the shoulder joints and the angles and the angular speeds of the knee joints are obtained through an angle information processing system; the angular speeds of the shoulder joints and the angular speeds of the knee joints are judged to obtain a present gait phase.The gait phase distinguishing method aims at providing a method for setting the mapping relationship between the upper-and-lower limb movement in the human-body gait movement process in the biped walking process.According to the gait phase distinguishing method, the angle information on the horizontal plane, the coronal plane and the sagittal plane is received through the neck angle sensor, the large arm angle sensors, the thigh angle sensors and the shank angle sensors to complete gait phase judgment of the upper limbs and the lower climbs; the structure is simple, and installing is convenient.

Description

technical field [0001] The invention relates to the motion control of the knee joint of an intelligent artificial limb, in particular to a gait phase discrimination method based on the motion information of the upper and lower limbs. Background technique [0002] With the aging of the population and the significant increase in the number of patients with motor function loss caused by diseases and car accidents, how to assist the elderly, the weak and the disabled in the field of rehabilitation, respond to the national policy of helping the elderly and the disabled, and reduce labor costs has become the focus of prosthetics research. [0003] Prosthetics are artificial prostheses specially designed and fabricated to compensate for amputations or incomplete limb defects by means and methods of engineering technology. Its main function is to replace part of the functions of the lost limbs, so that the amputees can restore a certain ability to take care of themselves and work. ...

AI Technical Summary

Problems solved by technology

Bipedal walking is a process of neuromuscular coupling and body coordination. Since the existing research mainly focuses on the lower limb gait, it is difficult to fully describe the human gait movement. In the field of gait, the posture information of the upper limbs and the coordinated movement of the upper and lower limbs still need further breakthroughs.
