(Universidad Santiago de Cali, 2023) Gutiérrez Lemos, Ana Carolina; Peláez Arias, Shirley Dahiana; Bermeo Varón, Leonardo Antonio (Director)
The anterior cruciate ligament is one of the parts of the knee that is most affected when lower limb injuries occur. Most of these injuries are treated by surgery, which requires a post-surgical rehabilitation that consists of recovering the angle of movement during flexion of the joint. This rehabilitation phase is called the acute phase, where the physiotherapist indicates the rehabilitation angles subjectively. Due to this subjectivity, in this work a device is developed to assist the first phase of therapy following an anterior cruciate ligament injury, by flexion and extension of the joint at home. The device consists of an active orthosis with a degree of freedom where 10 minutes of therapy with two different angles of flexion and extension are programmed. Tests were performed on 11 healthy people, 1 person who suffered knee dislocation, 2 people with ligament reconstruction, and 1 person undergoing rehabilitation of anterior cruciate ligament injury. The results indicate that the device could contribute to acute-phase knee rehabilitation at home with a satisfaction level of 84%.
