  text: "<jats:title>Abstract</jats:title><jats:sec>\r\n                <jats:title>Background
    and aims</jats:title>\r\n                <jats:p>One reason for the controversial
    discussion of whether the dual task (DT) walking paradigm has an added value for
    diagnosis in clinical conditions might be the use of different gait measurement
    systems. Therefore, the purpose was 1) to detect DT effects of central gait parameters
    obtained from five different gait analysis devices in young and old adults, 2)
    to assess the consistency of the measurement systems, and 3) to determine if the
    absolut and proportional DT costs (DTC) are greater than the system-measurement
    error under ST.</jats:p>\r\n              </jats:sec><jats:sec>\r\n                <jats:title>Methods</jats:title>\r\n
    \               <jats:p>Twelve old (72.2 ± 7.9y) and 14 young adults (28.3 ± 6.2y)
    walked a 14.7-m distance under ST and DT at a self-selected gait velocity. Interrater
    reliability, precision of the measurement and sensitivity to change were calculated
    under ST and DT.</jats:p>\r\n              </jats:sec><jats:sec>\r\n                <jats:title>Results</jats:title>\r\n
    \               <jats:p>An age effect was observed in almost all gait parameters
    for the ST condition. For DT only differences for stride length (<jats:italic>p</jats:italic> &lt; .029,
    ɳ<jats:sup>2</jats:sup><jats:sub>p</jats:sub> = .239) as well as single and double
    limb support (<jats:italic>p</jats:italic> = .036, ɳ<jats:sup>2</jats:sup><jats:sub>p</jats:sub> = .227;
    <jats:italic>p</jats:italic> = .034, ɳ<jats:sup>2</jats:sup><jats:sub>p</jats:sub> = .218)
    remained. The measurement systems showed a lower absolute agreement compared to
    consistency across all systems.</jats:p>\r\n              </jats:sec><jats:sec>\r\n
    \               <jats:title>Conclusions</jats:title>\r\n                <jats:p>When
    reporting DT effects, the real changes in performance and random measurement errors
    should always be accounted for. These findings have strong implications for interpreting
    DT effects.</jats:p>\r\n              </jats:sec>"
