Electronic Prosthetics for the Rehabilitation of the Carpal Tunnel Syndrome

The following research presents the construction and operation of a prototype of a robotic prosthetics, which will help to improve their quality of life the patients suffering from carpal tunnel syndrome. The prototype provides a complementary rehabilitation, when the patients suffer from this pathology, in addition the prototype can be utilized for other related syndromes that need periodic rehabilitation. The prototype was developed in such a way that it consists of three parts and a shield structure, which are part of an exoskeleton designed for 3D printing that fits comfortably to the user’s arm. The device is portable when operating with a rechargeable battery and control is carried out by a programmable card which is in order of the operation of the rotary actuators, the position sensor, the screen, the indicator LED, the push buttons and the wireless communication. For an improved interaction with the user, an interface was developed complying with Google Play policies for an Android device; in which you can choose the exercise and the number of repetitions in a simple way. The robotic prosthetics imitates rehabilitation exercises performed by the physiotherapist, with the difference that you have a control of work angles in each exercise. Three patients were tested for quicker and more effective results; the prototype was adjusted to a one patient’s hands, obtaining favorable results in a short time based on the visual pain scale.
