A precision grip, also known as a pincher grip, is a type of hand grasp where the pad of the thumb opposes the pad of the index finger to manipulate small objects.
This grip allows for fine motor control and dexterity, enabling actions like picking up a bead, turning a page, or threading a needle. It differs from a power grip, which involves using the entire hand to grasp larger objects with force.
Here's a breakdown of the key aspects of a precision grip:
- Fingers Involved: Primarily the thumb and index finger.
- Purpose: Manipulation of small objects requiring fine motor control.
- Mechanism: Pads of the thumb and index finger are brought together in opposition.
- Examples: Picking up a small bead, writing with a pencil, fastening a button.
- Alternative Names: Pincher grip.
- Contrast with Power Grip: While a precision grip uses fingertips for control, a power grip uses the whole hand for strength.
The precision grip is essential for many daily tasks and relies on the coordinated action of muscles, nerves, and bones in the hand and arm.
