A Real-Time Feedback Rehabilitation Training Pen

This rehabilitation training pen is specifically designed for hand rehabilitation in stroke patients, comprising three main components. The front end features a resistance-equipped clamp that facilitates finger strength training, incorporating a game element to enhance engagement. The middle section simulates the tactile feel of piano keys, allowing patients to practice finger flexion and extension through piano games. The rear end is equipped with an interactive feedback module that provides visual, auditory, and tactile vibrations to promptly inform patients about the correctness of their movements and to offer motivation. The entire design is detachable, making it easy to store and transport.
