5.9 Visual analogue scale (VAS)
The visual analogue scale in the patient record can be used for assessing the progress
of the therapy.
The VAS measures the patient’s subjective pain sensation on a scale from 0 to 10,
within which the patient can classify his or her pain intensity. The starting point (0)
stands for “no pain” while the ultimate point (10) stands for the “worst imaginable
pain”.
In each therapy session, the patient is asked once again to assign a value to the pain
he/she has felt since the last treatment.
The reduction in VAS values over the course of the therapy gives an indication of the
success of the treatment.
• Touch and drag the arrow to move it to the point on the scale
(see picture below) where the patient has assigned his or her pain intensity.
• Touch “OK” to x the arrow.
