By clicking on the Practice button, the patient can use the virtual arm to
practice their control. The default is non-compound movements; if you go
back to 'Rest', the hand will return to a neutral position. Click the check box
for compound movements if you wish to use the virtual arm in the same
manner that it will be used in the actual prosthesis; when you return to 'Rest',
the hand will remain in the last position achieved.
On the home page, there are 6 game options explained in the table below.
Mimic the flash cards as they are presented; the patient has 1 minute to
complete each task. Read the description before the level to understand the

After each level, if you proceed to the score page, you will see the completion
percentage. You may also track this in the history page.
Other Options
On the home screen, various other options also exist to change the difficulty
of the game.
Repetitions
This value indicates the number of times you will see each movement flash
card (or combination of flash cards for multi degree of freedom levels).
Speed
This value indicates how quickly the virtual arm will move. Decrease this
value to slow down the arm and make the level easier.
Note: Always check the calibration with the virtual arm before
using it to control a prosthetic device.
Note: Following calibration with the GUI, the prosthetist should
test the ability of the user to adequately perform movements and
manipulate each degree of freedom in the terminal device
