I our study CRF there is a question that is aimed to be answered by VAS, Visual Analogue Scale.
On the hard copy CRF the patient is asked to mark a point on a ten centimeters scale, that will be measured by a ruler to get a definite value.
Is there any way to represent this VAS scale on OpenClinica?
An idea that has occurred in our firm is to create a computerized ruler that would measure the distance between the mark (held by the mouse) and the end of the row, and show it on the screen.
That way one could set the sign at the exact location that indicates the distance he asks for.
