Kinematic analysis of an eight bar exoskeleton mechanism for knee joint

Knee is the largest and most complex joint in the body and while walking, sitting and any other activity the body weight is transmitted to the knees. So the knee joint is more prone to injuries than any other joint. Due to the harmful changes in human lifestyle, different diseases like stroke and problems in musculoskeletal system are increasing noticeably. So one of the solutions to the knee problems is to use the supportive tools. For this purpose, in the research ahead, designing a wearable robot to help injured people in walking will be dealt with. The central feature of the knee wearable robots, is that the knee regains the ability to walk by the help of a mechanism and this facilitates life for the people with knee disabilities. Wearable robots not only help these patients to use their disabled organs and walk, but also have a significant mental effect on them. The kinematic analysis of an exoskeleton orthosis, designed for patients who have pain in one of their knees is presented using vector loop method.
