Research On The Quantitative Evaluation Method Of Human Balance Ability Based On Multimode

Relevant data show that with the increasing of aging in China,the risk of falls in the elderly is also increasing,The decline of bones and organs in the elderly will lead to the decline of body balance,Balance ability is an important index to measure the normal movement and maintain the posture of human body,and it can prevent the risk of falling,Therefore,it is very important to evaluate the balance ability,but the mechanism of the balance ability can not be clearly described,and a large number of experts and scholars need to continue to study in this field.First of all,through the establishment of human body balance and the determination of the overall idea of the study,the object of study is established,and the acquisition mode and muscle selection of the experiment are effectively explained.Then according to the experimental acquisition method,the multi-modal signals of the experimenter are collected according to the experimental requirements.Secondly,by comparing the traditional filtering process with the wavelet transform filtering process,Extract the eigenvalues in time domain,Extract the frequency-domain eigenvalue and draw the change image of the frequency-domain eigenvalue with the sampling point,The spectrum and power spectral density are used for analysis.Finally,the chaos theory is used to reconstruct the phase space by determining the best delay time and selecting the best embedding dimension,Establish comprehensive indicators and evaluation mechanism of balance ability,Through the classification and quantitative comprehensive evaluation of the level of balance ability.
