Finger adduction
By spreading the fingers, a flat, thin object (< 3 mm/< 0.12 inch)
can be held between the finger joints when closing the hand.
Spreading the fingers is most effective with the power grip. It can
also be used with the key grip and finger point. This grip
cannot
be selected in the adjustment software.
Application examples: makes it possible to hold thin objects effect
ively (e.g. magazine, cutlery, toothbrush).
Hook grip
This grip corresponds to a power grip with the fingers only partly
closed. It makes it possible to engage objects with carrying loops
and can also be initiated from the relaxed hand position. This grip
cannot
be selected in the adjustment software.
Application examples: this grip makes it possible to carry bags.
Active index grip
All fingers close and can pick up an object while the index finger
remains extended. Subsequently the index finger can be individu
ally flexed or extended by the user. An open signal causes the index
finger to extend first followed by the remaining fingers. The object
is released from the hand.
Application examples: this grip can be used for example to operate
spray bottles.
Pinch grip
For this grip, only the index finger and thumb meet while the
remaining fingers close.
The thumb position has to be adjusted for this grip so it can be car
ried out precisely (see page 16).
Application examples: this grip makes it possible to grasp small
objects (e.g. house keys, coins, closures, pens).
Precision closed grip
The middle finger, ring finger and little finger are closed. The
thumb moves to a half-closed position. Subsequently the index fin
ger can be individually flexed or extended.
The thumb position has to be adjusted for this grip so it can be car
ried out precisely (see page 16).
Application examples: this grip makes it possible to grasp small
objects and makes working at a table easier.
Precision open grip
The middle finger, ring finger and little finger remain open. The
thumb moves to a half-closed position. Subsequently the index fin
ger can be individually flexed or extended. The thumb has to be
adjusted for this grip so it can be carried out precisely (see
page 16).
Application examples: this grip makes it possible to grasp small
objects.
