Neuroprosthesis Programs
There are three Neuroprosthesis Programs D, E, and F that are designed to help perform
a specific task, such as opening a door or grasping an object. They start when the trigger
button on the Control Unit or Orthosis is pressed. They continue until the trigger button
is pressed again. Neuroprosthesis programs have no set program time. The duration is
determined by task/user.
Program D—Open Hand
Activates the hand to open and remain open until the trigger button is pressed again.
Program E—Grasp and Release
Activates the hand to grasp and hold objects using a palmar grasp. When the trigger button
is pressed, a half-second pause is followed by a pre-defined duration of hand opening. The
hand then closes and remains closed until the trigger button is pressed again to release the
grasp. Once the trigger button is pressed the second time, a half second of continued flexor
stimulation is followed by an adjustable duration of extensor stimulation to open the hand.
The stimulation then shuts off, and the hand relaxes.
Program F—Key Grip
Program F is used to grasp and hold small items in a lateral grasp (or key grip) between
the thumb and the lateral side of the index finger. Program F holds the fingers in flexion
throughout the operating phases.
When the trigger button is pressed, the thumb opens. The thumb then closes and remains
closed until the trigger button is pressed again to release the grip. Once the trigger button is
pressed the second time, extensor stimulation opens the thumb. The stimulation then shuts
off, and the hand relaxes.
Motor Neuromodulation Program
Program G—Extensors and Flexors, Extensors Only, Flexors Only
There is one Motor Neuromodulation Program G that delivers rapid bursts of stimulation
to the flexors and extensors, the flexors only, or the extensors only. The program is started
and paused by pressing the trigger button on the Control Unit or Orthosis. Program time can
range from 5 to 30 minutes.
