Effect of wobble board training on movement strategies to maintain equilibrium on unstable surfaces
Abstract Standing on unstable surfaces requires more complex motor control mechanisms to sustain balance when compared to firm surfaces. Surface instability enhances the demand to maintain equilibrium and is often used to challenge balance, but little is known about how balance training affects movement strategies to control posture while standing on unstable surfaces. This study aimed at assessing the effects of isolated wobble board (WB) training on movement strategies to maintain balance during single-leg standing on a WB. Twenty healthy men were randomly assigned to either a control or a training group. The training group took part in four weeks of WB training and both groups were tested pre and post the intervention. Electromyography from the supporting lower limb muscles, full-body kinematics and ground reaction forces were recorded during firm surface (FS) and WB single-leg standing. WB training did not affect FS performance (p = 0.865), but tripled WB standing time (p Highlights Effects of WB training on balance strategies on unstable supports were quantified. WB training did not improve firm surface single-leg standing balance performance. WB training improved the performance when single-leg standing on a WB. WB training improved counter-movement strategies to maintain balance on a WB. WB standing time correlates to reduced trunk and swing leg counter-movement velocity.
