Range of the clearance parameters for 2010 measurements for men, women and total (aged 66 to 71). The parameters are heel strike pitch angle (θY), maximum heel clearance (MaxHC), the first and second local maxima of the toe clearance (MaxTC1 and MaxTC2 respectively), minimum toe clearance (MinTC) and minimum of the toe clearance velocity (VMinTC). The mean, standard deviation (SD), median ([10th; 90th] percentiles) over the individual mean values have been presented. * shows the existence of significant difference between male and female participants.
