After both recordings have been performed, make sure
that both recordings set are selected (check mark).
By scrolling down and clicking on "Create test set", a
test set is created from the two recordings and stored
temporarily in the Myo cuff ➞ The test set is lost after
switching off the Myo cuff.
Step 7: Test reliability of the patterns
The user can now test the reliability of the control in real
time in the menu "Spiderplot / Training"
- Each shape represents a pattern
- Each function in the prosthesis is

- As the user recreates each

Evaluate the prosthetic control together with the user by
using the spider plot and/or the movement display.
If the prosthesis control is working reliably, continue
with the basic set. Reliably means that the prosthesis
generates the desired movements and the user has little or
no problems with the execution of the movement patterns.
Test all recorded movements using the Spider Plot or
Movement Display.
Step 8: Create Basic Set
- As before, click on the arrows
- For each arm position, record 2
- A basic set can only be created
Troubleshooting basic control
Poor quality of motion or accuracy:
After creating the basic set, if certain motions or arm
positions create poor movement quality, you may uncheck
those data sets, then click on "Creating a Test Set" to
evaluate movement quality without the suspected poor
data.
If control has improved, re-record the unchecked data set,
and create a new Basic Set. Test function again.
Difficulty creating differentiated patterns:
Make sure the user is trying to create motions in their
phantom limb that they can imagine doing. Be sure to have
a clear understanding of how their phantom limb feels, and
what "motions" they can try to create.
The quality of the Basic Set is of great importance as it
creates the foundation for how the system operates and
recognizes muscle activity patterns.
Once a reliable Basic Set has been created, additional
grip patterns can be added.
