acc_max = peak total acceleration at initial ground contact, acc_swing = mean total acceleration during swing phase, dur_step = duration of complete step cycle, Max = maximum value, Min = minimum value, rel_stan = percentage of stance phase in the total step cycle, SD = standard deviation of the mean; W-C = walk on concrete; W-R = walk on rubber mats.
