VAS Search Method
In VAS Search method, first Ramp & Hold stimulus with predefined intensity and duration is
given and the subject is asked to estimate the perceived magnitude of pain. The intensity of
the next stimulus is set according to the response – increases if the reported pain rating is
lower than the desired, decreases if the reported pain rating is higher than the desired. The
step size by which the intensity of the next stimulus is changed can be predetermined during
program creation or set by the operator during the test. The VAS Search method can be used
to individually define what temperature is associated with patient's pain rating.
The temperature associated with the subject individualized rating of pain can be determined in
one of two modes – automatic and manual.
In Manual mode only the first stimulus is predefined, the intensity of the next stimulus is set
by the operator during the program run using the following window that pops up after each
trial:
