The bebionic small hand provides 14 different grip patterns, allowing the user to have a more
complete device to assist them in their day to day life. The hand has two selectable thumb
positions: opposed and non-opposed.
Opposed places the thumb in opposition to the fingers on the hand, allowing grips like
Tripod and Power.
Non-Opposed places the thumb parallel with the fingers of the hand and allows grips like
Key and Finger Point.
Opposed Non-Opposed
Introduction

The hand is supplied preset in Mode 4. This provides two
input operation with proportional control of grip and speed.
Speed and grip force are set to maximum.
To alternate between the default and alternative grip
pattern, an OPEN OPEN signal must be applied (i.e. the
hand must be fully opened, the signal relaxed and then a
second open signal supplied). To alternate between the
primary grip pattern table and secondary grip pattern table,
press the Program Switch for less than two seconds. The
Auto Grip feature is turned off.

Factory Settings
A Program Switch is provided on the back of the hand.
This has four functions;
1. Switch the hand ON and OFF
A single press for approximately three seconds will switch
the hand OFF. A single press for more than two seconds
will switch the hand ON.
2. Alternate between the primary and secondary
grip patterns
When the hand is switched ON, a single press of less than two seconds
will alternate between the primary and secondary grip patterns. This will be
accompanied by a short bleep and vibration (if activated on bebalance).
3. Enable / disable the in-hand bluetooth module
With the hand switched ON, a single press for more than six seconds will enable the
bluetooth module. A double beep/vibrate will indicate connection has been made.
Pressing the switch again for more than two seconds or disconnecting the power to
the hand will disable the bluetooth module.
4. Enter / exit glove mode as follows
With the hand switched OFF, press the switch until the thumb begins to drive in.
Then release the switch. For more information please see page 20.
Program Switch

Power
With the thumb opposed, all four fingers close into
the palm until they meet resistance or the close signal
stops. When fingers are approaching a fully closed
position, the thumb drives in to cover the fingers for
additional grip security. This pattern allows round
objects such as a ball or a piece of fruit to be held
securely. This grip can also provide a handshake.
Cylindrical shaped objects such as bottles, home
and garden utensil handles are also held easily and
securely.
Tripod
When the thumb is opposed, the hand closes into
Tripod Grip with index and middle fingers meeting the
thumb. Ring and little fingers continue to close until
they meet resistance or the close signal stops. This type
of grip allows users to pick up, hold and manipulate a
variety of everyday objects such as car keys, coins, jar
lids and pens.
Hook
With the thumb in opposed position, a partially closed
Power Grip provides Hook Grip. This is ideal for
carrying a shopping bag or briefcase. Hook Grip can
also be achieved by closing the fingers from the relaxed
hand position.
Finger Adduction
The fingers of the bebionic hand move together
naturally as the fingers close. This allows the user
to securely grip thin objects, such as cutlery or a
toothbrush, between the fingers to achieve function in a
different plane. Finger Adduction is most functional with
the hand in Power Grip but can also be achieved with
the hand in Key Grip and Pinch Grip.
Grips
Opposed - Thumb in opposition to the fingers

Active Index
With the thumb opposed Active Index Grip will grasp
the handle of an object with the middle, ring and little
fingers and secure the grip with the thumb. The index
finger will then close – this may be positioned over the
lever of the device held such as a spray bottle, it also
offers the ideal finger position for typing. The index
finger is under independent user control and may be
positioned accordingly. To exit Active Index, an open
signal will fully open the index finger before the other
fingers and thumb release their grip.
Precision Closed
This grip can be used in situations similar to the
Precision Open Grip, but where extended fingers
would be obstructive, such as working at a desk.
Initially the middle, ring and little fingers close into the
palm. The thumb moves to the midpoint of its range
and pauses. The Index is then active and 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 the index finger.)
Precision Open
With the thumb opposed, the index finger meets
the static thumb allowing the user to pick up and
manipulate small objects. When this grip is selected
and a close signal is applied, the thumb closes to the
midpoint of its range and pauses. The index is then
active and under user control. The middle, ring and
little fingers remain extended. (To achieve this grip it is
necessary for the thumb to be manually repositioned
by the practitioner/technician so that the thumb only
contacts the index finger.)
Pinch
The thumb only contacts index finger and is used for
the fine manipulation of objects. To achieve this grip it
is necessary for the thumb to be manually repositioned
by the practitioner/technician so that the thumb only
contacts the index finger.
The bebionic hand MUST NOT be used to operate a firearm
