Multi-body-position pressure balance evaluating system

Abstract

The invention discloses a multi-body-position pressure balance evaluating system, comprising a sensor array, a control unit, a processing unit, wherein the control unit is used for acquiring a plurality of electrical signals from a plurality of pressure sensing points by a signal collection unit; the processing unit is used for acquiring pressure data according to the plurality of electrical signals, preprocessing the pressure data, then carrying out feature extraction on the preprocessed pressure data, and carrying out feature selection on balance evaluation data to obtain evaluation data; on this basis, a prediction model is established, and a limit value of pressure evaluation is obtained according to the prediction model; the limit value is compared with the acquired pressure sensing array data of a patient, so that a quantified evaluation result is obtained. The multi-body-position pressure balance evaluating system can be used for carrying out static balance evaluation on multiple body positions such as sitting, standing, flatly lying and the like as well as carrying out dynamic balance evaluation on rehabilitation training sports and the like, and is capable of giving quantified balance evaluation results, thus realizing automatic and efficient balance evaluation. Furthermore, based on daily life scene, balance evaluation scene interactive games are developed by the system, so that the enthusiasm of the patient for rehabilitation training can be enhanced.

Description

Technical field [0001] The invention relates to a balance assessment technology, in particular to a multi-position pressure balance assessment system. Background technique [0002] Balance function is an important function of human beings and basic motor skills. Various actions in daily life depend on effective balance function. Many diseases can cause balance dysfunction and seriously affect the quality of life of patients. For example, limb motor dysfunction caused by cerebral palsy, stroke, spinal cord injury, and brain injury in children will affect balance function. Both research and clinical studies have shown that for patients with limb motor function, through timely and effective rehabilitation training and assessment, part of the patient's limb motor function can be restored, the patient's ability to take care of themselves in life, and the disability rate can be reduced. [0003] Balance assessment is divided into static balance assessment and dynamic balance assessment...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no automatic and efficient evaluation technology for balance evaluation, which makes this balance evaluation still rely on traditional manual recording and manual calculation, which restricts the development of this technology
