The finger pinch gauge can be used to measure pinch strength. It is
calibrated in pounds and kilograms of force.
Apply pinch force at the pinch groove while holding the pinch gauge
between your thumb and finger(s). When force is applied farther
toward the tip the reading will be slightly higher. When force is applied
farther toward the rear the reading will be slightly lower.
The gauge must be “zeroed” before each pinch test. Grasp the knurled
ring of the dial indicator and rotate it until the zero on the dial indicator
is directly under the black pointer.
The red maximum pointer must be reset before each pinch test.
Rotate the small knurled knob on top of the dial indicator in a
counterclockwise direction until it rests against the black pointer at the
zero marking. The red maximum pointer will remain at the subject’s
maximum reading until it is reset.
Use the pinch gauge to perform the three basic pinch tests:
• Tip Pinch
- thumb tip to index fingertip
• Key Pinch
-thumb pad to lateral aspect of middle phalanx of index
finger
• Palmar Pinch
- thumb pad to pads of the index and middle fingers
