Training included experiencing losses of balance due to internal or external perturbations while performing voluntary tasks. The tasks were of four types: stable, quasi\u2010mobile, mobile, and unpredictable, each with choice of three difficulty levels (normal, increased, or reduced). Multiple linear regression (reactive balance outcome) and negative binomial regression (fall rates) were used to model associations between training characteristics (total number of perturbations, task difficulty, perceived challenge, and success rate) and post\u2010training fall rates and changes in the reactive balance control sub\u2010score of the mini\u2010Balance Evaluation Systems Test (mini\u2010BESTest).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A higher number of perturbations were significantly associated with better post\u2010intervention reactive balance scores on the mini\u2010BEST (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.010).
