Gait was examined under three conditions: unassisted walking; walking with a 4\u2010wheeled walker; and walking with a 4\u2010wheeled walker while completing a secondary task. Conditions were performed across two walking paths: straight and figure\u2010of\u20108 Walk Test. Separate mixed\u2010methods analyses of variance (ANOVAs; within\u2010subject: condition\/path; between\u2010subject: group) were used for statistical analyses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Velocity was lower when walking using a walker while completing a cognitive task (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001), in the figure\u2010of\u20108 Walk Test (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001), and in older adults (<jats:italic>p<\/jats:italic>\u00a0=\u00a0.001).

Walking more complex configurations resulted in the prioritization of gait over the cognitive task while performing the dual\u2010task conditions. No evidence of an age\u2010related difference in the effect of initial walker use on gait was observed. Nonetheless, walkers are cognitively demanding and their introduction should warrant a clinical
