To access gesture control:
1. Hold i-Limb hand parallel to the ground (elbow bent to 90°)
2. Maintain an open signal until index finger twitches
3. Move the i-Limb Quantum hand (within 1 second) in direction assigned to the desired grip
4. The i-Limb Quantum hand will adopt the grip
5. 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 co-contraction. This
is changed using the Biosim and My i-Limb app.
App Control (available on all i-Limb hands)
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.
Muscle Control (available on all i-Limb hands)
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.
You can use the app to turn on muscle control.
Proximity Control (available only on i-Limb Quantum hands)
Grip chips are small Bluetooth devices which change the function of the i-Limb Quantum hand when the hand
comes close to them.
To use Grip Chips, make sure the i-Limb hand is not connected to the Biosim or My i-Limb app.
Proximity is accessed by holding the i-Limb hand fully open near (15 cm/ 6") to a Grip Chip. Wait until the grip is
accessed, which may take up to 3 seconds. To exit a grip accessed via proximity control, give a long open signal.
Double tapping a Grip Chip activates the grip. Quickly tap a Grip Chip twice, just like double-clicking a computer
mouse. The LED on the Grip Chip flashes once when tapping is successful.
NOTE: A 3 second pause between each double tap is required. The pause prevents the grip chip from incorrectly
detecting multiple taps in a very short period of time. This can cause the hand to enter a grip and then immediately
exit it again.
The i-Limb must be fully open/digits stalled open for proximity or tapping to be successful.
The individual Grip Chips are programmed using the Biosim and the My i-Limb app and can be reprogrammed by
the user at any time.
I-LIMB HAND COVERS
Donning a Cover
To don a cover, bring i-Limb hand into the position shown in figure 28 and turn the hand off. The position can also
be achieved using the don/doff quick grip.
Donning the i-Limb Skin Active, i-Limb Skin Contour and i-Limb Skin Natural covers:
1. Line up cover with the fingers of the i-Limb hand, and slide cover downwards.
2. When the fingers are mostly donned, pull the thumb opening over the thumb (Fig. 29).
3. Slide the remainder of the cover over the i-Limb hand (Fig. 30).
4. Make sure each digit tip is fitted to the cover.
5. Do not pull the cover too tightly over the hand.
Donning the i-Limb Skin Match cover:
6. Spray the outer surface with isopropyl alcohol (Fig. 31).
7. Invert the cover to the level of the finger openings (Fig. 32).
