Aim: This study's purpose is to estimate the effect of an elastic rubber band ankle strapping on the postural control with or without underwrap. Method: 15 healthy volunteers have been tested on a 2 feet standing position while performing a task under 3 conditions 1) without being strapped 2) with the strapping over the skin 3) with the strapping over and underwrap. The variable on trial, recorded using a force platform, was the pression center movement (CP) defined by its frontal (AP) and medial (ML) axes. We extracted CP trajectories decomposed into two elementary motions: (1) the horizontal displacements of the centre of gravity (CG) and (2) the vertical projection of the difference between centre of pressure and the centre of gravity (CP-CG). Results: The only statistically significative decrease of variance from the no strapping condition was with over skin strapping condition for the CP and CG on ML axe. No CP-CG variance was significally modified. Conclusion: The over skin strapping provide a lateral stabilization. The hypothesis of additional sensory information and mechanical restriction of the ankle could provide explanation.
