Shoulder Physio Device Monitoring Using ESP32 Microcontroller And Web Applications

Abstract

Physiotherapy is the process of monitoring and treatment applied directly to the physical body, usually involving injury such as in physical muscle by methods such as massage, heat treatment, and exercise rather than by drugs or surgery. Most physiotherapists, use the traditional method by relying on impairment measures such as range of motion and muscle strength and closely monitoring continuously on the patient progress. This traditional method may affect the standardized measures thus implying the effectiveness of the physiotherapy process itself. Therefore, it will impact the patient’s healing process due to incorrect exercise. For that reason, the objective of this project is to help the user who has a shoulder problem to be able to monitor their shoulder angle movement while doing the physiotherapy process. This system consists of a microcontroller ESP32 as the main controller to process the signal input/output and as a communication device to connect with Wi-Fi adaptor, a flex sensor to measure the angle of the shoulder movement in one abduction axis. The OLED are used to display the desired angle movement and the buzzer only give the alert sound when the angle is reach at 90°. This system communicates with the Web Applications to display the real-time shoulder angle position and also can act as secondary monitoring for the user or physiotherapist who treats them. The circuit has been designed with the smallest possible size to ensure the user is comfortable with the prototype. This prototype has been successfully tested and can be one of the effective methods to aid people with shoulder posture-related problems.
