Synthesis for a Knee Rehabilitation Mechanism Applying Genetic Algorithms

摘要

This article presents the synthesis of a Slider-crank mechanism, as an instrument for the rehabilitation of knees produced by different types of injuries. According to the physical activities performed by the users, atrophy of muscle groups around the knee is generated. The development of the proposed mechanism involved the biomechanical analysis of movements developed by health professionals during a rehabilitation session. This analysis was carried out through software based on digital image processing, obtaining the points of objective trajectory that the mechanism should imitate. Subsequently, a set of optimal solutions was obtained, applying the technique of genetic algorithms. The solutions obtained allow the designer to take into account factors such as the mechanism's developed trajectory quality, as well as its size. They even allow you to select the degree of importance according to your requirements.
