Development of an Active Orthosis and Internet of Things (IoT) Application for Lower Extremity

Abstract

The IoT (Internet of Things) technology has begun to draw attention in the field of sports sciences, as it has in numerous other domains. In athlete rehabilitation, this technology offers significant advantages over its older versions and demonstrates superior capabilities. This study is structured into three phases aimed at developing a new-generation active lower extremity rehabilitation system based on IoT. In the first phase, an active controlled orthosis design will be developed for the lower extremity. The controller for the active orthosis will employ the admittance control method. In this method, admittance A will be manipulated with small or zero, low deviations to control the rapid rise (lifting) effect, achieving the desired force response during treatment. This study holds intrinsic value in filling a gap within the existing literature. The second and third phases will focus on developing an adaptable active orthosis design capable of transferring data to mobile applications for athletes and sports physicians. This system distinguishes itself from others with these features. The developed system can be personalized for athletes, enabling the physician to easily monitor the recovery process of multiple athletes via a mobile device and provide real-time feedback on device usage to the athlete. The system instantaneously records the pressure applied by the patient to the sensor, and when the pressure surpasses the threshold set by the doctor, notifications and vibrations are sent to the athlete. Consequently, the athlete's monitoring and treatment processes can proceed without intervention.
