Clinician Manual

This document provides instruction for prosthetists in the fitting and servicing of i-digits™ and
should be read in full prior to fitting. It is highly recommended that the use of this manual is
made in conjunction with instruction from a clinician experienced in upper limb and myoelectric
prostheses.

1.0 i-digits™
1.1 Product Description
design. dexterity. intelligent motion.
i-digits™ is a fully customized partial hand prosthesis with
individually powered fingers. i-digits™ fingers work in con-
junction with any remaining fingers to help significantly
increase functional capabilities for users of the device.
Based on the industry-leading design of our i-limb®prod-
uct range, i-digits™ combines unsurpassed functionality
with style.
i-digits™ quantum incorporates gesture control via the pat-
ented and ground-breaking i-mo™ technology and is the
first partial hand prosthesis that can change grips with a
simple gesture.
Key features include:
• Smarter*
-gesture control powered by i-mo™ technology
uses simple gestures to change grips
-proximity control made available via grip chip tech-
nology
• Faster*
-adjustable speed boost increases speed up to 30%
• Stronger*
-up to 30% more power when needed
-improved component design for easier and more
reliable fabrication
-50% longer battery life
• Smaller
-form fitting design decreases device size in every
dimension
-smaller digits now available
1.2 Intended Use
i-digits™ is intended to be used by patients with partial
hand loss or deficiency. Devices are suited to patients with
any 3, 4 or 5 digit loss, while patients with 1 or 2 digit loss
are also indicated typically when the digits of loss are either
the thumb or the main digits of opposition, namely the in-
dex and middle fingers.
* not available on i-digits™ access
i-digits™ oers compliant grip through individually pow-
ered digits with stall out ability. A manually rotating thumb
in conjunction with a pulsing, enhanced grip (vari-grip), an
anti-drop safety feature (auto-grasp) and the wide range of
automated grip patterns lead to broad functionality.
Users can choose from a wide selection of automated grips
and gestures to help complete daily tasks. Grips can then
be customized further for precise control.

1.3 User Selection
i-digits™ is appropriate for users with partial hand loss or
deficiency; where the level of loss or deficiency is:
• Distal to the wrist
• Proximal of the metacarpo-phalangeal joint
i-digits™ is not indicated for users with:
• cognitive impairment, such that the device is unable
to be controlled
• where skin integrity is insucient to support a pros-
thetic device
1.4 Prosthesis Overview: Control Options
i-digits™ can access automated grips using a range of con-
trol options.
gesture control (i-digits™ quantum only):
By enabling i-mo™ technology, gesture control allows an
automated grip to be accessed through a smooth and nat-
ural motion of the prosthesis in 1 of 4 directions.
To access gesture control:
• Device must be in full open hand mode
• Hold arm parallel to ground (elbow bent to 90°)
• Maintain an open signal until finger twitches
• Move the hand (within maximum 1 second) in direc-
tion assigned to desired grip
• i-digits™ quantum will adopt the grip
Note: gesture control can also be accessed using co-con-
traction. Depending on how your clinician has set up your
prosthesis for you.
app control:
i-digits™ can access a grip at the touch of an icon on the
my i-limb™ app and biosim™ app, enabling all automated
grips to be available. These are called quick grips™.
i-digits™ will exit automated grip when icon is tapped
again, or by selecting another grip icon.
Speed boost (not available on i-digits™ access) is also
available on the app using a simple slider bar. This in-
creased speed can provide benefits of a more responsive
action, more natural appearance of motion and increased
grip force.

muscle control:
Triggers are specific muscle signals that you can use to in-
struct i-digits™ to activate an automated grip. There are
4 potential triggers: hold open, double impulse, triple im-
pulse and co-contraction.
proximity control (not available on i-digits™ access):
grip chips™ are small Bluetooth chips which can change
the programming of the i-digits™ when you position it near
to the chip. The grip chips™ can be positioned around the
user’s environment in practical locations to allow access
to the optimum grip for particular daily tasks. Individual
grip chips can be programmed using the biosim™ or my
i-limb™ app. Refer to i-digits user manual (MA01421) for
further information on set up and use.
