Proposal for a layer-based IoT construction method and its implementation and evaluation on a rolling stand-up walker

Abstract

Abstract It is a problem that the poor gait function of many elderly people affects their activities of daily living (ADL), and deteriorates their quality of life (QoL). To enhance rehabilitation of the gait function, it is desirable to increase the amount of training received. In this research, we develop a measurement system for a gait training device that enables effective rehabilitation using the internet of things (IoT) and measurement technology proactively, which aims to realize gconstant rehabilitation h by considering ADL (except training time) as rehabilitation. We propose an IoT measurement system model that classifies each function of the IoT system in a hierarchical structure to promote systematic development more efficiently. Based on this model, we (1) modularize a device for measuring the upper limb load, acceleration, and gait distance, (2) develop a device for presenting the target value of rehabilitation visually to the user using the internet, and (3) implement the model on a commercial rolling stand-up walker and gait training device. We confirm that we can obtain excellent measurements using each mounted module.
