In any trial or report that contains videos and/or a 3D avatar, a moving vertical solid line will be visualized and played in the graphs that is in sync with the trial's media. This line is called a
playheadA playhead is a vertical solid line, displayed in a graph, that is synchronized with other trial's media (e.g. video or 3D avatar)
. Synchronizing data and media allows you to analyze the data in the appropriate visual context of the patient movements at that moment, like in the video of the section below. Depending on the type of graph, either one or two playheads will be shown:
Graphs that have only one channel (no left and right, like trunk or pelvis data) have one playhead.
Graphs that have channels for left and right (e.g., legs) have two playheads, one for each side (red and green, respectively).
In case data is plotted over gait cycles instead of a timeline, the gait cycles are plotted on top of each other in a graph. The active gait cycle will be highlighted, together with the corresponding stance-to-swing
transition lineA vertical line indicating the transition from stance to swing phase (moment of Foot Off)
if available, to indicate synchronization with the trial's media (see video below).
