A Child Orthosis Design and Simulation Based on Dynamic Considerations

摘要

This paper addresses a knee orthotic system design used on a 4-year-old child with locomotion problems. This knee orthotic system design was made by performing a dynamic analysis of the proposed child locomotion system. The aim of this dynamic analysis was to obtain knee joint connection forces in case of a walking activity. For the proposed dynamic model, input data such as hip, knee and ankle joint motion laws were considered. These were obtained through an experimental analysis with a high-speed video camera equipment on a healthy child. Thus, a database was created, which was used as input data for numerical simulations made in a dynamic mode with MSC Adams. Through these numerical simulations, important results were obtained, and these will further validate the proposed prototype.
