  1. Table 2 shows ICC(2,1) values and significance levels (in parenthesis) for intertester reliability (Rater 1 vs. Rater 2) for step execution parameters Initiation Phase Duration (IPD), Preparatory Phase Duration (PPD), Swing Phase Duration (SPD), Foot-Off Time (FOT) and Foot-Contact Time (FCT) under single and dual task conditions calculated separately for elderly subjects (N = 16), younger adult subjects (N = 24) and the pooled population of elderly and younger adult subjects (N = 40). An average of all six step trials (three forward and three backward) was used in the analysis (ns – not significant, *p < 0.05, **p < 0.01, ***p < 0.001).
