Desarrollo de un sistema de rehabilitación basado en un equipo electromecánico para recuperación de motricidad de mano y dedos post intervención por síndrome del túnel carpiano

Abstract

This technological proposal was oriented to the development of an electromechanical rehabilitation system based on virtual environments for the recovery of hand and finger motricity post intervention due to Carpal Tunnel Syndrome (CTS) for which a bibliographic research was carried out where information was found on: definition, causes, effects and which the recovery treatments are. Based on this, a post-intervention motor recovery protocol for the parts affected by CTS was established. A database was also obtained where the anthropometric measurements of a group of students were determined and used for the sizing of the device. Once the rehabilitation protocol and anthropometric measurements were obtained by means of computer-aided design (CAD) software, an electromechanical model was developed for the induction of finger and hand movements. Subsequently, the design was validated prior to construction, where an analysis, selection of materials, hardware and software suitable for the electromechanical system was carried out, allowing the generation of graphic environments and with resources for linking it to the electromechanical system. It should be taken into account that the results achieved are adjusted to the dimensions of the subject assessed, therefore, the angles vary in the range established within the programming. When the tests were carried out at station A (wrist rehabilitator), the acceptance rate was above 93.5%, and at station B (finger rehabilitator) the acceptance rate was above 95%. In conclusion, the device responds to each of the objectives set out for the development of the project presented; however, in order to increase the acceptance percentages, the research carried out can be extended.
