[0002] The recovery of neurological function after spinal cord injury has become a global problem. The patient's ability to take care of themselves in daily life is significantly reduced after the injury. Even for those who partially retain upper limb function, although they can rely on the strength of their upper limbs and wrists to push the wheelchair and achieve therapeutic transfer activities, this is not enough for young patients to meet their life needs; some patients with cervical spinal cord injury can retain the flexion and extension activities of the upper limb shoulder and elbow joints, including shoulder lifting, translation, elbow flexion and extension movements, but the wrist joints and fingers only have slight contraction. Some patients have finger muscle strength of level 0, and their fingers have no active movement at all. The hands are mostly in a fist shape, and the patients cannot move their hands, so their daily life, communication, and work are severely restricted; but for children, young and middle-aged people, it is particularly important to use electronic products such as computers and mobile phones to increase their communication with the outside world and broaden their future learning and re-employment scope. Currently, fingerboards are common on the market, and are mainly used to maintain posture for patients with increased muscle tone or flaccid paralysis in the hands. There is no device to assist fingers in typing keyboards for patients with hand dysfunction after spinal cord injury. Therefore, it is necessary to design a wrist, palm, and index finger fixation brace that can control finger movements through upper limb movement to perform operations such as typing on the keyboard, mouse, and sliding mobile phone pages, thereby improving patients' daily life, work, and communication methods.
