This device was engineered specifically for the Within Reach challenge. Its primary function is an active augmentation of the fingers that enables individuals with chronic flexion contracture to regain optimal hand functionality. The extension is achieved by manipulating the tensioner, which in turn moves the fingers via cables secured distally within the extensor portion. Velcro tape is used to secure the prosthesis to the patient's arm. The tensioner can be easily locked or unlocked by depressing its bar laterally. The posterior fixation of the finger in this prototype is accomplished using a plate devoid of any specialized locking mechanism, relying instead on friction with the finger for stability. While this may suffice, further testing is required to confirm its effectiveness. This initial model represents a first attempt, and subsequent updates are highly probable as refinement and improvement continue.
