Changes in postural stability induced by a ball-and-board game designed from a systems perspective

• From the existing literature on lower limb injuries, we identified the need to incorporate a systems perspective into the design of an original game that challenges postural stability.

• The amount of variability in postural oscillations evolved heterogeneously across participants with practice, which may indicate an exploratory behaviour towards the development of a new motor skill.

• Better performance was characterized by postural oscillations with a less periodic – more complex – variability structure, enhancing adaptability to balance perturbations.
