Technical University of Denmark (DTU) is undertaking research to increase the understanding of lateral ankle sprains and the mechanical parameters such as friction. This basic research also enable us to do applied research with the Spraino in situations that are otherwise not safe or less safe and therefore unethical to perform in a movement laboratory with human subjects. The research focuses on testing Spraino vs. no Spraino conditions an various conditions with attenuated Spraino stabilizing function. The research is aiming to improve Spraino and the model will enable us to further develop it for outdoor use. The reseach is conducted by Associate Professor Ion Sivebæk who is a leading expert in nanotribology.
