Summary: | One of the early symptoms of musculoskeletal disorders is called "locomotive syndrome" (Locomo). There is a qualitative index called "Locomomo-Degree Test," which can to determine whether a person has Locomo or not, but has issues in safety and simplicity. As a preliminary step to establish an automatic and quantitative evaluation method of Locomo degree, we tried to determine whether a person has Locomo or not by using acceleration sensor and a machine learning model. To investigate a new index to discriminate Locomo from the characteristics of human movement and to obtain the independent variables for machine learning, one-legged stand test and alternate one-legged stand test were conducted for elderly persons. A statistical method, multivariate logistic regression analysis and a machine learning method, Gradient Boosting Decision Tree (GBDT), were used to predict the presence or absence of locomotion. As a result, the performance of GBDT exceeded that of our previous study. |
