Fig. 6From: A novel accelerometry-based algorithm for the detection of step durations over short episodes of gait in healthy elderlyAverage absolute differences in step duration within trials and for each subject are presented for each pair of compared methods with a boxplot (a). Percentage of average absolute differences in step duration over the average step duration calculated with both systems within trials and for each subject are presented for each pair of compared methods with a boxplot (b). *LB = low-back accelerometry, HE = heel accelerometry, OP = Optotrak. The boxplot includes minimum, first quartile (q1, 25 %), median, third quartile (q3, 75 %), maximum and outlier valuesBack to article page
