MC Powered Flexion Wrist
User Guide
Introduction
The Motion Control Powered Flexion Wrist (PFW) provides powered wrist exion/extension or radial/ulnar
deviation with an on-board microprocessor (Figure 1). This controller provides proportional control and switching
of function between the terminal device and powered wrist exion/extension or radial/ulnar deviation. By using
an industry standard quick disconnect, the PFW/TD unit can easily be removed from the prosthesis and another
manufacturers’ terminal device may be inserted in its place. The MC Powered Flexion Wrist is durable and water
resistant/ submersible up to the quick disconnect wrist. The microprocessor provides easy adjustability via
wireless Bluetooth® communication to iOS devices (iPhone®, iPad®, and iPod Touch®).

The Powered Flexion Wrist should not be used in situations where inadvertent movement or lack of
intended motion may cause injury to the user or others, such as driving a vehicle, operating heavy
equipment, using power tools or handling hot liquids.
Do not use the Powered Flexion Wrist in environments where it may be subjected to greater than
50 lbs/22.7 kg of force.
The Powered Flexion Wrist has a pinch danger when it is near or at maximum exion or extension
(Figure 2).
Special Precautions
Adjustment
See Quick Setup Guide for PFW, later in this document.
Maintenance
The Motion Control Powered Flexion Wrist does not require any routine maintenance. Avoid using any
lubricants, liquids, or cleaners on any surfaces of the Powered Flexion Wrist.
Figure 2
The Powered Flexion Wrist should be adjusted for individual patients using the MCUI iOS user
interface. Factory Settings will seldom be the optimal settings for the user.
Figure 3
Caution should be used when operating the wrist around volatile gases. The wrist utilizes an electric
motor that can ignite volatile gases.
The coaxial plug may require periodic cleaning. This is accomplished using a Q-tip
and a very small amount of rubbing alcohol.
Follow up visits should be made to the prosthetist, at least yearly, to ensure the user
interface settings do not require readjustment.
Extension Stop
The Powered Flexion Wrist includes an extension stop (circled in Figure 3). This
stop can be removed easily with a 3/32" hex wrench to increase extension range, if
desired.
Quick Disconnect Wrist
The Quick Disconnect wrist is a universal design that allows interchangeability with our
other terminal devices, such as the MC ProPlus Hand, and other manufacturers’ devices.
Instructions for Use
Insert the quick disconnect wrist on the Powered Flexion Wrist into the wrist on the forearm. While pushing it
in rmly, rotate the Powered Flexion Wrist until an audible click is heard. It is advisable to rotate the device in
both directions several clicks, then attempt to pull the Powered Flexion Wrist to ensure it has attached rmly.
To disconnect the Powered Flexion Wrist rotate it either direction until a slightly more dicult click is felt.

Overcoming this click will disconnect the ETD from the forearm. This allows interchangeability with another
terminal device, such as the MC ProPlus Hand.
iOS User Interface
The Motion Control Powered Flexion Wrist communicates via Bluetooth® directly with Apple® iOS Devices.
The MCUI App is available at no charge from the Apple® App Store. No additional hardware or adapters are
necessary with the iOS Interface. Note: The MCUI App is not available for Android devices.

iOS Adjustments for Powered Flexion Wrist
1. Motor Speed
This adjustment allows the user to ne tune the
desired speed of the device. Lower speeds result in
ner control, higher speeds, quicker response. The
slider can be adjusted from Low to High to optimize
the speed for the user.
2. Motor Brake
This adjustment allows for enabling/disabling the
internal motor brake. When the motor brake is
enabled, passive resistance is substantially increased.
3. Home Position Delay
The PFW will pause at a "Home" position. The length
of pause is adjustable. Set Home Position Delay to
zero (0) if no pause is desired.
4. Calibrate Home Position
This will determine where the user would like the
Home Position centered in the full range-of-motion.
Default Position will set the Home Position centered
in the full range of motion. To change the Home
Position, move the powered exion unit to desired
Home Position and touch the Current Position tab to
set a new Home Position.
5. Calibrate Range of Motion
If you remove or add the physical extension stop
(Figure 4) a short calibration sequence will nd the
correct end points for the new range-of-motion.
Declaration of Conformity
