Study On The Measurement And Evaluation Of Muscle Strength In The Elderly

Nowadays,the aging of the population in China is deepening.Pension problem has become a great challenge for our country.However,the old age service mode is not perfect,which is the urgent need to solve in pension service industry.Due to the lack of objective and fair basis,it is very important to study a simple and objective evaluation method.Under this background,this thesis mainly carries on the following research.Firstly,the structure and movement mechanism of the upper and lower limbs are analyzed.Considering the weakness of the elderly and the common characteristics of the index selection in the research of the older people at home and abroad,seven dimension muscle indexes are selected based on the principle of index screening.The index system for evaluating the muscle strength of the elderly is established.Secondly,based on the elderly muscle strength evaluation index system,the muscle strength test specification is established.The isometric muscle strength of subjects is tested by using Hoggan hand-held dynamometry MicroFET3.The experimental collected data are analyzed by the Spss software.And the validity of the experiment and the reliability of the experimental data are verified.It provides data support for the study of evaluation methods.Thirdly,in order to evaluate the reliability,a variety of comprehensive evaluation methods are explored.The entropy weight fuzzy comprehensive evaluation method and the improved grey relational analysis method are mainly studied.Two kinds of muscle strength evaluation models are established,and the evaluation results are obtained respectively.The comparison and analysis of the evaluation results show that the improved grey relational analysis method is effective for the elderly muscle strength assessment.This method meets the needs of quantitative assessment of the elderly muscle strength,and provides an evaluation basis for personalized service of the elderly.Finally,the requirement analysis of the system is carried out,and the improved grey relational analysis method is applied to the design of the evaluation system.Through the construction of the evaluation platform of the elderly human strength,the functions of rapid evaluation and data management are realized.The results of the system evaluation are consistent with the expected results,and the function of the system is verified.
