Grips with opposed thumb (the thumb is opposite the palm)
Tripod grip
The index finger and middle finger are closed simultaneously with
the thumb until the three fingers touch. Ring and little fingers con­
tinue to close until they meet resistance or the close signal stops.
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 can be used to grasp and hold
objects (e.g. pens, coins).
Power grip
All fingers close until they encounter an object or the close signal
stops. The thumb then moves towards the palm as well.
Application examples: this grip can be used to hold round objects
(e.g. fruit, balls, glasses).
