Gesture Control (available only on i-Limb Quantum hands)
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 user’s requirements
using the My i-Limb app.
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 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 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 activate and program muscle control.
Proximity Control (available only on i-Limb Quantum hands)
Grip Chips are small Bluetooth devices which activate grips on the i-Limb Quantum hand when the prosthesis is
moved close to them or by tapping the Grip Chip.
Before operating a Grip Chip for the first time, pull the plastic tab out of the device to engage battery.
To use Grip Chips, make sure the i-Limb hand is not connected to the My i-Limb app.
• Proximity is accessed by fully opening the i-Limb hand near (15 cm/ 6”) a Grip Chip and then relaxing the
muscles. 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 My i-Limb app and can be reprogrammed by the user at any
time.
Replacing the Grip Chip battery
The battery is expected to last 6 months. Battery life is reduced if Grip Chip is stored close to the i- Limb hand.
Battery is not rechargeable.
– To replace the battery, insert fingernail between upper and lower caps and run around join to release.
– Remove battery. Insert new battery under retaining clip, ensuring writing on battery is facing outwards.
– Replace the caps by pressing upper and lower caps together.
