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; T-C = trot on concrete; T-R = trot on rubber mats.
