Nowadays, the importance of orthosis has increased to people of different ages due to the type of activity and the increase in activity of musculoskeletal disorders and stimulation of the elbow, such as elbows, in order to prevent and cure diseases including The range of motion of various parts including the elbow, such as the elbow, is of interest, where the orthosis is designed in the Solidworks software. The purpose of this orthosis construction is to assist normal elbow movements by using elastic structures such as springs with a lock-like structure, orthopedic designs that can perform flexion at various angles. By releasing any of the screws in the articulation, it can extend it further into the flexion or allow the articulation to return to the full extension. Repeating this operation, the individual is in the process of recovery. In this study, the types of elbow orthosis are examined. At the end, the frequency and thermal analysis is investigated and the results are reported.
