Why is pinch grip important?

Allows us a great deal of dexterity and precision adjustment, but, since the proximal finger surfaces (nearest to palm) and the palm are not used, the pinch grip is only about 25% of the maximum grip strength possible (the power grip). Pinch grip strength decreases rapidly at spans less than 1" or greater than 3".

Is a pinch grip stronger than a power grip?

A. The amount of force one is capable of exerting is greater for the power grip than for the pinch grip. B. The force generated with a pinch grip is about 15% - 25% of the force generated with a power grip, depending on the type of pinch grip and the worker's individual force capable.
