The MyoPro® is a Myoelectric Arm Orthosis designed to support a weak or deformed arm. The MyoPro can enable individuals to self-initiate and control movements of a partially paralyzed or weakened arm using their own muscle signals. When the user tries to bend their arm, sensors in the brace detect the weak muscle signal, which activates the motor to move the arm in the desired direction. The user is completely controlling their own arm; the brace amplifies their weak muscle signal to help bend and move their arm. With the orthosis, a paralyzed individual, such as one who has suffered a brachial plexus injury, stroke or other neuromuscular disorder can perform activities of daily living including feeding, reaching and lifting.
Introducing the MyoPro Motion-G Elbow-Wrist-Hand Orthosis. The MyoPro Motion-G is
the next generation of the MyoPro myelectric upper extremity orthoses and combines
myoelectrically driven 3-jaw chuck grasp with the current myoelectric elbow and
manually articulated wrist system. It is designed to increase functional capability for the
user by enabling partial finger movement and resulting hand control.
The MyoPro Motion-G orthosis is designed to help individuals with upper extremity
paresis regain the ability to perform ADLs through the addition of grasp and release.
Empowers a user to complete additional functional tasks by enabling grasping of
objects along with elbow flexion and extension
Promotes independent activity and safety through functional assistance
How It Works
The MyoPro Motion-G orthosis is based on decades of work in myoelectric orthotics and
prosthetics and represents the state of the art in functional orthotics for individuals with
upper extremity paresis. Sensors built into the custom device detect the EMG signal in
the affected arm in four locations - bicep/tricep and the forearm flexor/extensor muscle
groups. These signals are amplified when a user initiates movement, driving small
motors which allow the individual to extend/flex their elbow and open/close their
thumb and fingers. The wrist can be manually positioned and controlled in
flexion/extension and pronation/supination.
The MyoPro Motion-G may provide functional benefit for individuals with hemiparesis.
Other criteria include:
Viable proximal and distal EMG signal
Appropriate passive range of motion
Wrist extends to neutral position or further
Hand and fingers to full extension
The MyoPro® Motion W™ can now provide 4 degree of freedom movement. This is accomplished using a myoelectric driven
motorized elbow joint along with a manually set multi-articulating wrist. The multi-articulating wrist extends the
functional benefits of the MyoPro orthosis and can provide the following clinical benefits:
Flexion / extension, radial / ulnar deviation
Rotation - pronation / supination
Allows the user to have multi-axial movement at the
Adjustable ratcheting and tension for each degree of
