Gesture control
Enables an automated grip to be accessed through a
smooth motion of the prosthesis in one of four directions
(forward, back, left or right). The grips programmed for
each direction are customized to the users requirements
using the biosim
®
and my i-limb
®
app.
To access gesture control:
• Hold i-limb
®
hand parallel to the ground (elbow
bent to 90°)
• Maintain an open signal until index finger twitches
• Move the i-limb
®
hand (within 1 second) in direc-
tion assigned to the desired grip
• The i-limb
®
hand will adopt the grip
• To exit the grip hold an open signal until the hand
exits the grip
Default setting for gesture control is hold open, however
it can alternatively be accessed using cocontraction. This
is changed using the biosim
®
and my i-limb
®
app.
App control
An automated grip can be accessed at the touch of an
icon on the biosim
®
and my i-limb
®
app. These are called
quick grips
®
. The i-limb
®
hand will exit the grip when the
icon is tapped again or by selecting another grip icon to
enter.
Speed boost is also available on the app using a simple
slider bar. The increase in speed of the digits oers a
more responsive action, more natural appearance and
increased grip force potential.
Muscle control
Triggers are specific muscle signals that can be used to
access an automated grip. There are 4 potential muscle
triggers: hold open, double impulse, triple impulse and
co-contraction.
Proximity control
Grip chips
®
are small Bluetooth
®
chips which can
change the programming of the i-limb
®
hand when you
position the hand near to the chip. The grip chips
®
can
be positioned in practical locations to allow access to the
optimum grip for particular tasks at that location. The in-
dividual grip chips
®
are programmed using the biosim
®
or my i-limb
®
app and can be reprogrammed by the user
at any time as required.
For further information on grip chip use and set up refer
to i-limb hand user manual (MA01382).
