Example of signals from the inertial sensors and stabilometer for one subject. Example of signals from the inertial sensors and stabilometer for one subject 1 s before the step. a) acceleration in the ML plane, b) acceleration in the AP plane, c) acceleration in the vertical plane; f) angular velocity in the ML plane, g) angular velocity in the AP plane, h) angular velocity in the vertical plane. d) is the CoP displacement in the ML plane, and e) is the CoP in the AP plane. Note that the CoP signal is repeated to allow for an easier comparison of the main APAs characteristics with the inertial sensors. The dotted lines show the beginning of each phase of the APAs. The green lines indicate the SD of the signals for 5 trials.
