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 46).
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 46).
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 46).
Application examples: this grip makes it possible to grasp small
objects.
Grips with the thumb in the lateral position (the thumb is sideways to the palm)
Column grip
The thumb closes towards the palm, then the remaining fingers
bend over the thumb. In doing so, the thumb blocks the closing
movement of the index finger and lets it protrude beyond the other
three fingers.
Application examples: this grip can be used to push large buttons
(e.g. light switches) and for putting on clothes.
