Q-Sense Technical Reference Manual
Proprietary 76 of 188
Note that this program is available only with special license and not
a part of basic Q-Sense configuration
 Manual – The operator will initiate the onset of the stimulus
after the defined ISI.
First destination
temperature (°C) Defines the destination temperature for the first trial. Valid range is
limited by safety limitations and depends on the duration time.
Destination Rate
(°C/sec) Defines the temperature change rate from the baseline to destination
temperature. Valid range: 0.1 to 2°C/Sec
Duration Time (sec) Defines the duration for Thermode temperature to remain at
destination temperature before returning to baseline. Valid range: 0 to
600 (sec)
Return Rate Defines the temperature change rate from the destination to baseline
temperature. Valid range: 0.1 to 1°C/Sec
Search Mode Search mode:
 Automatic – starting from the second trial, the stimulus
parameters will be defined automatically by the predetermined
target pain rating and step size.
 Manual – At the end of each trial the user will define the
destination temperature of the next trial, until the desired pain
rating is reached. The user also decides when to finish the
program (i.e. when the desired pain rating is achieved). In
manual mode the 'Target Pain Rating' and 'Step size'
parameters become dimmed.
Target Pain Rating Relevant for Automatic search mode only.
Defines the pain rating that needs to be reached. If the actual pain
rating of the current trial is lower than 'Target Pain Rating' value, the
temperature of the next trial will increase by the Step Size (see below)
and vice versa.
Valid range: 1 - 100
Step Size (°C) Relevant for Automatic search mode only.
Determines the step size by which the temperature will increase/
decrease in every new trial. The direction of the temperature change
will depend on the difference between the target and the actual pain
ratings (see above in 'Target Pain Rating' description)
Valid range: 0.1 – 10 (°C)
Waiting time for
response (sec) Time for which the pain rating dialog will remain on the screen waiting
for user to respond.
ISI Min (sec) Minimum Inter-Stimulus-Interval (ISI). Valid range: 0 to 600 (sec)
ISI Max (sec) Maximum Inter-Stimulus-Interval (ISI). Valid range: 0 to 600 (sec).
Actual ISI will be randomized between min and max values.
Standard Events Different evens which can be indicated during the test via TTL or
Sound. See section 7.6.7
