PUTTING YOUR MYOPRO 2 ON (“DONNING”)
The following pages include step-by-step instructions for putting the MyoPro 2 on (sometimes referred to as
“donning the MyoPro 2”).
WARNINGS REVIEW
BEFORE donning the MyoPro 2, review the warnings below:
WARNING: DO NOT expose the MyoPro 2 to flame or excessive heat; personal injury may
occur.
WARNING: The MyoPro 2 is a prescription device and should only be used as indicated under
clinical supervision of a Provider, or after receiving instruction from a clinical Provider for athome use.
WARNING: The MyoPro 2 is only to be used by the person for whom it is prescribed.
WARNING: Each component of the device is supplied for safety and best performance. Use all
provided components for optimal operation.
WARNING: ONLY use the MyoPro 2 upper limb orthosis on the prescribed elbow, wrist and
hand joints. Each MyoPro 2 is built specifically for a left arm or a right arm; never wear the
MyoPro 2 on the other arm.
WARNING: Tight straps may restrict the User’s circulation. Therefore, always check that straps
are not too tight throughout the User’s range of motion.
WARNING: Do not sleep while wearing the device as straps may alter the User’s circulation.
▲ CAUTION: If you detect fumes, flames, melting of components around the battery or battery
charger, or the device is hot to touch, TURN THE DEVICE OFF IMMEDIATELY and contact your
Provider.
PN 25623 Rev 011 8
STEPS FOR PUTTING YOUR MYOPRO 2 ON
1. POWER OFF: While donning, the MyoPro 2 should be turned OFF; check that it is OFF before starting to
put the MyoPro on your arm.
NOTE: Pads and straps should be fully air-dried from the previous use.
▲ CAUTION: Do not use a hairdryer to dry components of the MyoPro 2.
2. PREPARE: Place the MyoPro 2 in your lap, or on a flat surface that is not slippery.
3. HAND: Start with the hand support shell: check that the strap around the hand support shell is loose.
Feed your fingers through so the under side of the hand support shell sits in your palm, and your thumb
rests in the Thumb Saddle. Be sure the base of your thumb presses against the hard plastic (opposite of
the hand strap). Leave the fingers free while you continue to put the rest of the device on – we will
secure the finger support as the last step.
NOTE: The motor and battery case should rest on the outside of the arm. If the motor and
battery case is aligned along the interior of the arm, you may be donning upside down or on
the wrong arm.
4. WRIST: Lower your wrist into the multi-articulating wrist (MAW), rotation portion.
5. FOREARM: Lower your forearm into the forearm shell.
6. Secure the Forearm Closure.
7. FINISH LOWER ARM: Tighten and secure the Velcro hand strap. This will keep the MyoPro 2 in place
while you continue to don.

MODES OF USE
WARNING: Use caution when using the device in shoulder positions where it is possible for the
User to hit him or herself.
The MyoPro 2 may be used in a variety of modes. The different modes allow you to operate the MyoPro 2
by tensing or relaxing different muscles. You may find that you want to use different muscles – and
therefore different modes – when performing specific tasks with your MyoPro 2. Modes may be changed
using the buttons on the control panel.
When the device is fit to you, your Provider will optimize the sensitivity settings within each mode
depending on the strength of your EMG signal at that time. If over time you feel that the MyoPro 2 is not
assisting your arm or hand adequately, please contact your Provider; the sensitivity settings may need to be
readjusted.
START MODE
When you first power on the MyoPro 2, the elbow will be in Standby Mode. This setting may be changed by
your Provider.
ELBOW MODES
The elbow has four distinct modes of use when the MyoPro 2 is powered on.
1. Standby mode
2. Biceps mode
3. Triceps mode
4. Dual mode
These are explained in the following pages.
GRASP MODES
The grasp has four distinct modes of use when the MyoPro 2 is powered on.
1. Standby mode
2. Open mode
3. Close mode
4. Dual mode
These are explained in the following pages.
NOTE: You may experience a slight vibration of the finger support when the grasp reaches a
fully closed or fully open position. This would be caused by the hand motor turning on and off
as it detects the limits of its range of motion. This is normal operation, and nothing to worry
about.
PN 25623 Rev 011 25
ELBOW MODES
In this mode, neither the Biceps or Triceps Light will be
illuminated. The elbow motor will not respond to your EMG
signal from either muscle group.
Though the MyoPro 2 is powered on, no assistance is being
given to your elbow, and the arm will neither flex nor extend.
The sensors will be reading your EMG signal from both
biceps and triceps, but the motor response is paused.
Standby mode
Actions:
• This can be useful as a resting mode if straps or sensors
need to be adjusted, or if you want to take a short break
without turning the device off.
In this mode, the Biceps Light will be illuminated. The elbow
motor will respond to your biceps EMG signal.
Actions:
• When you relax your biceps, the device will extend.
• When you contract your biceps, the device will flex.
Biceps mode
PN 25623 Rev 011 26
ELBOW MODES, CONTINUED
In this mode, the Triceps Light will be illuminated. The elbow
motor will respond to your triceps EMG signal.
Actions:
• When you relax your triceps, the elbow will flex.
• When you contract your triceps, the elbow will extend.
Triceps mode
In this mode, both the Biceps and Triceps Light will illuminate.
The elbow motor will respond to your biceps and triceps EMG
signal.
The elbow will only respond to muscle contraction (not
Dual mode
relaxation, as in other modes) to assist you with active flexion
and active extension of your elbow.
You must engage both muscle groups in order for your arm to
move in both directions. The MyoPro 2 will respond to
whichever muscle signal is stronger at a given moment in time.
In order for Dual mode to be most effective, you should be able
to isolate the desired muscle (biceps or triceps) and have a
limited number of co-contractions prior to using Dual mode.
When used well, this mode should allow you greater ability to
hold an arm position at a mid-point between fully flexed and
fully extended.
Actions:
• When you contract your biceps, the elbow will flex, as long
as your biceps signal is greater than your triceps signal.
• When you contract your triceps, the elbow will extend, as
long as your triceps signal is greater than your biceps signal.
PN 25623 Rev 011 27
GRASP MODES
Standby mode
In this mode, neither the Close or Open Light will be
illuminated. The grasp motor will not respond to your EMG
signal.
Though the MyoPro 2 is powered on, no assistance is being
given to your hand, and the grasp will neither open nor close.
The sensors will be reading your EMG signals from both wrist
flexor and extensor muscle groups, but the motor response is
paused.
Actions:
• This can be useful as a resting mode if straps or sensors
need to be adjusted, or if you want to take a short break
without turning the device off.
In this mode, the Close Light will be illuminated. The grasp
motor will respond to your wrist flexor EMG signal.
Actions:
• When you relax your wrist flexors, the grasp will open.
• When you contract your wrist extensors, the grasp will

close.
PN 25623 Rev 011 28
GRASP MODES, CONTINUED
In this mode, the Open Light will be illuminated. The grasp
motor will respond to your wrist extensor EMG signal.
Actions:
• When you relax your wrist extensors, the grasp will close.
• When you contract your wrist extensors, the grasp will
open.
Open mode
In this mode, both the Close and Open Light will illuminate.
The grasp motor will respond to your wrist flexor and wrist
extensor EMG signal.
The grasp will only respond to muscle contraction (not
relaxation, as in other modes) to assist you with active close and
active open of your hand.
Dual mode
You must engage both muscle groups in order for your hand to
move in both directions. The MyoPro 2 will respond to
whichever muscle signal is stronger at a given moment in time.
In order for Dual mode to be most effective, you should be able
to isolate the desired muscle group (wrist flexors or wrist
extensors) and have a limited number of co-contractions prior
to using Dual mode. When used well, this mode should allow
you greater ability to hold a hand position at a mid-point
between fully closed and fully open.
Actions:
• When you contract your wrist flexors, the grasp will close,
as long as your wrist flexor signal is greater than your wrist
extensor signal.
• When you contract your wrist extensors, the grasp will
open, as long as your wrist extensor signal is greater than
your wrist flexor signal.
