Rocker type upper limb rehabilitation device and method for performing rehabilitation training by aid of rocker type upper limb rehabilitation device

Abstract

The invention discloses a rocker type upper limb rehabilitation device, which mainly consists of a mechanical portion and a control portion. The mechanical portion mainly comprises a base, a retractable rocker, an outer arc-shaped track and an inner arc-shaped track, the retractable rocker consists of a linear motor, and the outer arc-shaped track and the inner arc-shaped track are connected with a servo motor. The control portion mainly comprises a position sensor, a photoelectric encoder, a movement control card, a display and a computer, and the movement control card controls voltage and current of a servo motor driver and a linear motor driver. The mechanical portion is organically combined with the control portion, the retractable rocker can move in a three-dimensional space along an optional trace, three training modes including a passive training mode, an active training mode and an assisted training mode can be provided for patients losing motion abilities in different degrees, and accordingly the rocker type upper limb rehabilitation device is simple and compact in structure, diversified in training modes and low in cost, is applicable to extensive patients, and has a fine application prospect.

Description

technical field [0001] The invention relates to a rehabilitation training device for upper limb motor dysfunction, in particular to a rocker type upper limb rehabilitation device and a rehabilitation training method using the device. Background technique [0002] Research on rehabilitation robots began in the 1980s. Before 1990, mainly Europe, America and Japan were engaged in research in this area. After 1990, the research on rehabilitation robots entered a period of comprehensive development. Internationally, the research and development of rehabilitation robots is becoming more and more automated and intelligent. [0003] In China, the research on rehabilitation robots has a trend of increasing year by year. In 2008, Wang Zixi of Tsinghua University and others applied for a Chinese patent application with publication number CN101347380A "A Robotic Device for Hemiplegia Rehabilitation with Adjustable Training Plane". The upper limb rehabilitation robot device includes a...

AI Technical Summary

Problems solved by technology

The device has a simple structure and can meet the various training needs of patients, but it is only a plane training device in essence, so the rehabilitation training in three-dimensional space is limited to each plane, and it is impossible to realize the movement of any trajectory in three-dimensional space. Moreover, due to structural limitations, the device does not have flexibility when driving the patient's upper limb rehabilitation training, which may cause discomfort to the patient during rehabilitation activities.
