The Viedoc 4.33 release adds support for a Visual Analog Scale (VAS) in ViedocMe, enabling subjects to use the VAS scale to indicate and submit the intensity of perceived pain or disease symptoms. ViedocMe supports a 10 cm VAS on iPad Mini version 2-4 devices, and logs the device used by the subject when answering.
"The system is incredibly robust and is very user friendly, both to sponsor level satff, as well as site staff who remotely enter data."
