Research On Evaluation Of Human Balance Ability Based On Flexible Pressure Array Sensor

Balance ability plays a very important role in people's daily life.If the balance ability of the human body is damaged,it will lead to physical diseases such as fall,exercise control disorder and so on.Therefore,the assessment of balance ability studies the balance ability of healthy people,the fall of the elderly,and the balance dysfunction patients.Rehabilitation is very important.In this paper,a flexible pressure array sensor is used to quantitatively analyze the balance function of the human body.The Pro-Kin254 balance test and training system of Tecnobody company(Italy)is used as the standard balance test equipment,and the based on the flexible pressure array sensor and the Pro-Kin254 balance test and training system are compared.The similarities and differences of all kinds of balance parameters in the pressure center and the correlation of the assessment of the balance ability of the human body are carried out in this paper.The main achievements of this paper are summarized as follows:1.Using the test platform of Pro-Kin254 balance test and training system and flexible pressure array sensor,under the guidance of the rehabilitative physician,the balance ability of normal adults is detected.The data of the Pro-Kin254 balance test and training system are used as the standard to analyze the correlation of data collected by the two devices.To illustrate the role of flexible pressure array sensor in human body balance function detection.2.According to the biological structure of the foot and the experience of the predecessors,the foot is divided into 9 regions,and the algorithm is designed to automatically extract the foot pressure data of the flexible pressure array sensor,distinguish between the left and right feet,the foot print and the foot region pressure extraction.3.the concept of wavelet entropy and relative wavelet entropy is put forward.In the process of pressure analysis in all regions of the foot,the regularity of the dynamic balance test in the foot of the foot is explained.According to the classification rules of ATE,the data are divided into two categories,and the special points of the wavelet entropy of the two kinds of data are analyzed.
