Exercising for bedridden patients is an important challenge, particularly for individuals recovering from surgery, injuries, or living with chronic conditions that limit mobility. Prolonged immobility often leads to complications such as muscle atrophy, joint stiffness, and poor blood circulation. Upper limb exercises play a crucial role in maintaining physical function and promoting recovery, but these exercises are often challenging for patients to perform independently due to physical limitations. Patients normally require assistance from caregivers but this will consume longer time and effort. This project aims to assist bedridden patients in performing upper limb exercises more efficiently, reducing the time required for therapy while promoting muscle activity and improving blood circulation. The Portable Arm Exerciser provides several movements of the arm in a range from 0° to 90°, with different adjustment angles: 30°, 45°, and 90° and wrist for 45°. It uses an ESP32 microcontroller and a heartbeat sensor to track real-time heart rate, ensuring safety while displaying Beats-per-minutes BPM through the Blynk application. In conclusion, the Portable Arm Exerciser helps caregivers reduce time taken to do upper limb exercise for patients and helps patients to prevent muscle atrophy and improve blood circulation.
