Biodex Postural Stability System The group × time interaction was found to be highly significant for PST-API ( F =15.4, 1 54 p =<0.001, η p 2 =0.21) and PST-MLI ( F =4.35, 1 54 p =0.04, η p 2 =0.07) indicating that the multifactorial intervention had a differential effect on anterior-posterior and mediolateral stability over time.
