What is it about?
One type of balance assessment measurements is done standing on a freely moving platform after a sudden perturbation (nudge) of the platform itself. The task is to recover standing balance after the perturbation. We have explored how the motion that the participant is executing affects the effectiveness of the balance recovery and how this differs for standing on one or both legs.

Why is it important?
We found that choosing a more circular motion that uses both forward and sideways direction for two possible reasons. It can either quicken balance recovery, or it helps with successfully performing the recovery motion when standing on one leg (which is a difficult task to complete) without increasing the efficiency itself (as measured by damping ratio of the movement and the time to stop the motion).
