Abstract

In Honduras, a considerable percentage of the population works in different trades, one of them is sewing. Due to the repetitive motion that these people perform, they are very likely to suffer from osteoarthritis. In the study "Global Burden of Diseases (GBD)" osteoarthritis has increased its importance over the years, in 2019 about 142 million cases of people suffering from osteoarthritis were recorded. Hence the importance of creating devices that help heal or reduce the discomfort of this disease, which is why a prototype of an orthosis to reduce the discomfort caused by osteoarthritis during sewing work is proposed. The design of the orthosis is based on the union of different characteristics that present other already elaborated ones and thus create a design which can fulfill its objective using materials that are comfortable for the person as well as accessible. The added value of this design is to allow its use during the performance of their work thanks to its simple and practical design to be used as an accessory. The result is presented as a model in SolidWorks, performing specific simulations with which it is concluded that the device can be used in different temperatures, that the materials used comply with the necessary characteristics to adjust them to the hand and allow movement.
