IMU signals and relevant gait events. (a) Raw accelerometric signals: X L pointing downward (dashed line), Y L pointing forward (solid line) and ZL pointing laterally (dot-dashed line). SP-based gait event timings are superimposed (vertical lines). (b) Raw signal on X L and corresponding reconstructed signal (thick dashed line) used for the definition of the interval of interest. (c) Raw signal on Y L and corresponding reconstructed signal (thick line) used for the definition of the interval of interest. (d) Circles show the reference points used to estimate gait events from the accelerometric raw signals.
