Saving Changes
If the movements or positions are modified on the Calibration Setup tab, you
must recalibrate or update the classifier to permanently save them. You will
be prompted when you leave the Calibration Setup page by the following
options
Movement and position options are saved and reloaded each time you log in.

CALIBRATION
Introduction to Calibration
The pattern recognition algorithm must be calibrated for each specific user
and electrode locations. It may need to be recalibrated depending on daily or
long-term limb fluctuation, or prosthesis slip.
The patient will calibrate by viewing the image on their screen and copying
the movement with their phantom limb for the duration of the cue. They do
not need to copy the image exactly, only as a guide for which movement to
complete.
Repetition between the same motion and differentiation between separate
movements are extremely important. Remind your patient to complete a
medium contraction strength during calibration.
Calibration Window
When you open the Calibration window, you will be reminded which position
you are using to calibrate. Transhumeral prosthesis users will see the image
below. Use the button to move the elbow to the correct arm position, if the
elbow is externally powered.
