Wearable device to support stroke patient during lower limb rehabilitation

IoMT (Internet of Medical Things) is the combination of data from health measuring devices and mobile applications with a health management system, enabling remote disease treatment by healthcare professionals. This research aimed to design an IoMT system that can evaluate the rehabilitation of stroke patients through active range of motion exercises and send the data to physiologists to remotely assess the patient’s recovery. The system was developed using gyroscope sensors to calculate the range of motion (ROM) when patients perform rehabilitation exercises by sitting in a chair and extending their legs in front of them. It also utilizes microcontrollers for the purpose of displaying the completed repetitions on an LCD screen and transmitting data to the supervisor through the Blynk application. The initial test results were quite promising, as the system accurately tallied the number of completed repetitions, displayed it on the LCD screen, and alerted patients with a buzzer upon each exercise completion. Additionally, it measured and stored data regarding various angles of motion, which were then displayed in real-time on both the application and the LCD screen. (The number of degrees may be adjusted by the physiotherapist based on each patient’s condition.
