Abstract: Disclosed is a finger prosthetic is provided that could be attached to an individual's hand. The finger prosthetic includes a midsection, a fingertip portion, and a ring. The midsection, the fingertip portion, and the ring could be 3D printed and customized via 3D scanning The finger prosthetic includes a torsion spring system that comprises a fabricated torsion spring, a cable, and a pin. When the individual flexes their PIP joint, tension is generated in the cable and the cable pulls on the prosthetic fingertip thus flexing the prosthetic DIP joint simultaneously. When the individual wishes to extend the prosthetic DIP joint, he/she simply extends the PIP joint, causing the torsion spring to extend the prosthetic DIP joint. When the PIP joint is at rest, the cable will release the tension and the torsion spring will cause the DIP joint to extend to its upright position.

Abstract: A rehabilitation system is disclosed herein. In some embodiments, the rehabilitation system comprises a first computer terminal accessible by a first user, the first computer terminal having a memory for storing instructions including a game for rehabilitation of at least one of the first user's shoulder, elbow, wrist, or fingers; a sensor for detecting motion of the first user's hand as the first user is playing the game; a second computer terminal that displays the game in real-time on the second computer terminal as the first user is playing the game on the first computer terminal, and wherein a difficulty level of the game can be remotely adjusted from the second computer terminal; and a server that acquires rehabilitation data from the first computer terminal as the first user plays the game, and wherein the server permits access, on the second computer terminal, to the rehabilitation data collected.
