Frequency and duration of movement illusions and silent periods

Frequency and total duration of movement illusions and silent periods in Run 1 is shown as a function of the time of the onset of the event. ‘Onset’ indicates the time of onset of the event relative to the moment when vibration started (the whole duration of the event was measured, regardless of whether it finished within the 30 sec period or not). Note that extension responses initially dominated but were later replaced by the increasingly longer ‘no movement’ periods and, to a lesser extent, flexion responses.
