Hand fine motion ability testing and training device

Abstract

The invention discloses a hand fine motion ability testing and training device, which is composed of an arm bracket, a hand bracket, a force sensor, a programmed resistance source, a control box, a supporting table top, evaluation analysis software and the like. During testing, in order to prevent action compensation, an arm of a subject is tied to the arm bracket and a palm is tied to the hand bracket, a single finger or multiple fingers of the subject autonomously pull the knot at the stress application tail end and the wrist rotates leftwards and rightwards to obtain change signals of the force sensor, an angle sensor and traction rope length respectively, and the change signals are transmitted to the evaluation analysis software and can be used for quantitatively evaluating the motionability of wrist joints and finger joints of the subject, so that evaluation of the hand fine motion ability test is achieved. During rehabilitation training, a subject does actions with the same testposition, and the resistance output by the resistance source is adjusted, so that the finger joints and the wrist joints of the subject receive different degrees of resistance in the motion process,and the resistance training effect is achieved.

Description

technical field [0001] The invention relates to the fields of rehabilitation training and medical care, in particular to a device for testing and training fine motor skills of hands. Background technique [0002] Hand fine motor ability refers to the ability of the human body to complete specific tasks with the cooperation of various psychological activities such as perception and attention by means of small muscles or small muscle groups in the hands and fingers, which is the basis of daily life self-care ability Check indicators. Under the influence of aging, chronic diseases, etc., in the decline of human motor function, the ability to control fine movements of the hands is significantly reduced, especially the strength and joint mobility of fingers and wrists. [0003] In practice, the evaluation of hand fine motor ability is generally based on the completion of the simulated movements of the subjects, or the correlation analysis and evaluation of the finger movement si...

AI Technical Summary

Problems solved by technology

[0003] In practice, the evaluation of hand fine motor ability is generally based on the completion of the simulated movements of the subjects, or the correlation analysis and evaluation of the finger movement signals obtained by inertial sensors; in the practice of rehabilitation training, the current main focus is Rehabilitation training for neurological functions such as patient attention and coordination, as well as strength and mobility training for wrist joints, is mainly achieved by weight-bearing training; the formulation of rehabilitation training programs lacks quantitative basis, and the training process is less safe and effective
