Abstract

The growing prevalence of limb-related issues has increased the demand for rehabilitation services. A key focus has been on restoring upper limb functionality and controllability, which are essential for patients to reintegrate into society and improve their quality of life. In this project, a prototype for an assisted physiotherapy device was designed to rehabilitate frozen shoulders. The device supports both external and internal rotation of the shoulder, allowing movement from 0 to 90 degrees. Its adjustable speed control lets patients move their shoulders based on their personal needs and abilities. Additionally, the device provides real-time feedback on the angle, speed, and force applied during rehabilitation. Experimental results show that this prototype is both practical and effective in rehabilitating shoulder rotation.
