Architecture and Design of a Wearable Robotic System for Body Posture Monitoring, Correction, and Rehabilitation Assist

摘要

With the heavy use of consumer electronic devices (CEDs) like smartphones, laptops, etc. in daily life, more and more people feel head, neck, and back pains because of long time poor body postures during the use of these devices. This paper presents a patients-robots-doctors architecture and designs a wearable robotic system for body postures monitoring, correction, and rehabilitation assist. The system mainly includes a wearable robotic device (WRD) and the CEDs. The WRD monitors the postures of body segments and reminds the user to correct bad postures. The posture data are sent to CEDs for processing and visualization. The data can also be uploaded to a cloud server for professional analysis by doctors. The human body posture is modeled and simulated to show that the different postures of the body segments have large effects on the torques and forces acting on the joints and muscles. A posture detection method is proposed and the WRD is designed. The basic functions of the architecture and system are verified by experiments including head-neck posture, back posture, sleeping posture, and leg posture monitoring and correction warning. The architecture and system can be utilized not only by the patients-doctors in telerehabilitation exercise assist but also by the parents-children in good sitting habits development, the athletes-coaches and bodybuilders-instructors in training efficiency improvement, etc.
