From: Automated, IMU-based spine angle estimation and IMU location identification for telerehabilitation

Proposed IMU-based telerehabilitation system. IMU sensors, worn by the user, connect to the cellphone via Bluetooth. The IMU signal serves for both IMU location identification and angle estimation. The estimated angle is then utilized for real-time feedback and offline evaluation. Detection of incorrect IMU placement prompts user alerts to ensure accurate monitoring
