Figure 5From: Detection of anticipatory postural adjustments prior to gait initiation using inertial wearable sensorsDuration of APAs calculated using three different signals to determine the end f the APA. Duration of APAs calculated using the footswitch, stabilometer (CoP-AP), and the angular velocity sensor (UD plane) used to determine the end of the APAs. The actual end of the APAs is considered to be determined by the footswitch.Back to article page
