A robotic hand orthosis prototype has been created to aid in rehabilitating patients with digital nerve injuries, aiming to enhance functional recovery and reduce recovery time following surgery, potentially preventing stiffness in fingers that may necessitate further intervention if rehabilitation is neglected. In developing the prototype, various factors influencing its utility and effectiveness must be considered, including the choice of materials to balance comfort, adjustability, durability, and usability. The shape and fit of the orthosis play a crucial role in ensuring wearer comfort by aligning and supporting the hand and fingers in a natural and functional position. The critical element also involves the standards established by hand surgeons. A hand orthosis has been created to replicate the physical therapy conducted by hand therapists, encompassing three potential areas of intervention, operating independently, and utilising blocking mechanisms for other regions: isolated movement of the superficial flexor tendon of the long fingers, isolated movement of the deep flexor tendon of the long fingers and movement of the flexor pollicis longus tendon of the thumb. Furthermore, the intensity and range of motion will be adjusted to suit varying postoperative rehabilitation phases by creating an application. The orthosis was designed with environmentally friendly materials for sterilisation and reuse, considering patients’ allergies to latex and other materials while also considering functional, ergonomic, and aesthetic features to create a user-friendly device.
