Multi-position pressure balance evaluation system

Abstract

The invention discloses a multi-body position pressure balance evaluation system, which includes: a sensor array; a control unit, which collects multiple electrical signals from multiple pressure sensing points through a signal acquisition unit; and a processing unit, which collects multiple electrical signals according to multiple electrical signals After obtaining the pressure data, the processing unit preprocesses the pressure data and performs feature extraction, and performs feature selection on the balance evaluation data to obtain the evaluation data, and establishes a prediction model on this basis, and then obtains the limit value of the pressure evaluation according to the prediction model, The limit value is used for comparison with the collected pressure sensor array data of the patient, so as to obtain a quantitative evaluation result. The present invention can perform static balance assessment on multiple body positions such as sitting, standing, and lying down, and perform dynamic balance assessment on rehabilitation training exercises, etc., and provides quantified balance assessment results to realize automatic and efficient balance assessment. At the same time, based on daily life scenarios, interactive games for balance assessment scenarios are developed to enhance the enthusiasm of patients for rehabilitation training.

Description

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