Abstract
Currently a large number of hand injuries occur in the Mexican population, mainly caused by accidents at work and in sports activities. To help the population have access to a brachiopalmar rehabilitation, In this work it was proposed to develop a rehabilitative prototype “dynamic hand orthosis” to address the main pathologies that affect our society (fractures, dislocations, sprains, tendonitis and sx of the carpal tunnel). The design was analyzed in a finite element for its validation, having a safety factor of 2.6 and a maximum tension of 12.84 MPa below the ABS elastic limit, Manufacturing was done using a 3D printer with the ABS filament. This orthosis has an extensor finger attachment composed of hammocks, one for each finger. Due to its universal design, it can be used for both hands only by exchanging the extension of the thumb.
