*2.4. Walked Distance*

The participants were required to walk at a comfortable speed on a circuit with no half-turn or obstacle, graduated every 5 m. The distance walked by each patient was measured by the examiner using the scales marked on the ground. The estimated walked distance was calculated by multiplying the number of steps reported by the wearable devices by the average step length. The average step length was calculated using the method described by Bassett and Crouter [15,16]. This method consists of asking the participant to walk 20 steps at a comfortable speed and then measuring the distance walked. The average step length was then obtained by dividing this distance by 20. To weigh the variability of this measurement, we asked the subject to repeat the operation three times, after which we calculated the average step length from the three trials.
