Power

With the thumb opposed, all four fingers closeinto the palm until they meet resistance or theclose signal stops. When fingers are approachinga fully closed position, the thumb drives in tocover the fingers for additional grip security.This pattern allows round objects such as a ballor a piece of fruit to be held securely. This grip

can also provide a handshake. Cylindrical shapedobjects such as bottles, home and garden utensilhandles are also held easily and securely.

Tripod

When the thumb is opposed, the hand closesinto Tripod Grip with index and middle fingersmeeting the thumb. Ring and little fingerscontinue to close until they meet resistance orthe close signal stops. This type of grip allowsusers to pick up, hold and manipulate a variety ofeveryday objects such as car keys, coins, jar lidsand pens.

Hook

With the thumb in opposed position, a partiallyclosed Power Grip provides Hook Grip. This isideal for carrying a shopping bag or briefcase.Hook Grip can also be achieved by closing thefingers from the relaxed hand position.

Finger Adduction

The fingers of the bebionic hand move togethernaturally as the fingers close. This allows the userto securely grip thin objects, such as cutlery or

a toothbrush, between the fingers to achievefunction in a different plane. Finger Adduction ismost functional with the hand in Power Grip butcan also be achieved with the hand in Key Gripand Pinch Grip.

The thumb moves to the midpointof its range and pauses. The Index is then activeand under user control.(To achieve this grip it is necessary for the thumb

to be manually repositioned by the practitioner/technician so that the thumb only contacts theindex finger.)

With the thumb opposed, the index finger meetsthe static thumb allowing the user to pick upand manipulate small objects. When this gripis selected and a close signal is applied, thethumb closes to the midpoint of its range andpauses. The index is then active and under usercontrol. The middle, ring and little fingers remainextended. (To achieve this grip it is necessary forthe thumb to be manually repositioned by thepractitioner/technician so that the thumb onlycontacts the index finger.)

Relaxed Hand

The thumb is set to the non-opposed positionand partially driven in toward the palm. All thefingers are driven to a slightly flexed position.

Applying a further signal will drive the fingersinto Hook Grip for a carrying position.

Mouse

fingers providing stability. The index fingercloses on to the mouse button and then backsoff to provide the button press. Each closesignal will give a mouse click whilst an opensignal will release the mouse.

Switching Grip Patterns

The first grip pattern available, in each operating mode, should be the grip you willuse most frequently. You can then switch to a second grip pattern by applying eithera co-contraction or a double OPEN signal to the hand. It is then possible to switch toa further two grip patterns in each mode by pressing the programme switch on theback of the hand.

An additional three grips and positions - hook, finger adduction and open palm - areachieved as part of other grip patterns. This means you will be able to select up to 11grip patterns that will be most beneficial in your day-to-day life.

Note: - Your practitioner will work with you to programme the hand with the mostappropriate grip patterns to suit your lifestyle. They will also work with you to findthe easiest way to change between grips. For certain grip patterns, it is necessary forthe practitioner to adjust the thumb alignment, so that the contact position between

finger(s) and thumb is optimised. For instance, the thumb contacts the index finger forprecision and pinch, whereas in tripod the thumb contacts the index and middle finger.
