Spraino reduces impact coefficient of friction and inversion moment during mechanical simulations of the initial contact of a lateral ankle sprain injury in badminton

Lateral ankle sprains, a common injury in badminton, have recently been demonstrated preventable to some extent via the use of a new injury preventive device—Spraino (Lysdal et al., Citation2020). Spraino is designed to minimize lateral edge shoe surface friction, and thus reducing the inversion moment by bringing the ground reaction force vector closer to the ankle joint centre, in case of a landing with an initially inverted foot (Lysdal et al., Citation2022).

Testing the effect of preventive devices is a challenging task, however, as it is unethical to intentionally harm or risk the health of volunteering participants in the reproduction of injury scenarios.
