Proposal of Layer-Based IoT System Construction Method and Implementation to Rolling Stand-up Walker

It is a problem that the elderly to spoil gait function affects the activities of daily living (ADL), and deteriorates the quality of life (QoL). In order to enhance the effect of rehabilitation in the gait function, it is desirable to increase the amount of training. In this research, we develop a measurement system for a gait training device that enables effective rehabilitation utilizing IoT and measurement technology proactively, and aims to realize “constant rehabilitation” that consider daily lives except training time as rehabilitation. We propose an IoT measurement system model that classifies each function of IoT system in a hierarchical structure to promote system development more efficiently. Based on this model, we modularized a device for measuring the upper limb load, acceleration and gait distance, developed a device for presenting to the user via the Web, and implemented it on a commercial rolling stand-up walker and gait training device. We confirmed that we can measure normally using each mounted module.
