Construcción de un prototipo exo-esqueleto para rehabilitación de la mano: manufactura aditiva del exo-esqueleto de la mano y valoración funcional en el movimiento.

Abstract

The main objective of this work is the construction of an exo-skeleton prototype for hand rehabilitation and the development of a methodology for the additive manufacturing of the exo-skeleton and the functional assessment in movement. For the first stage, the starting point was a prototype previously designed and analyzed by the respective collaborators, and subsequently a preliminary study was carried out on the additive manufacturing of 3D printing in hand rehabilitation applications, analyzing the characteristics of the materials (filaments) existing in the market where criteria and recommendations for processing the elements of the exo-skeleton are established that allow the use of FDM technology for its construction with the help of the respective specifications, assembly plans and instructions. The second stage focuses on the functional assessment of the exo-skeleton prototype by recording movement (photogrammetry) and biosignal (dynamometer and EMG) of hand grip. These parameters will be useful for the implementation of regulations in ergonomics and in the survey of functional patterns as a standard reference and contrast between pathological and healthy subjects. This new study in our country creates new opportunities in the development of new technologies for health assessment.
