5 GRIP-POSITION PINCH GAUGE

| Pinch width can adjust to fit any hand size. Advanced protocols can now be performed with tip, palmar and key pinch strength tests.
---|---
| Pinch width without paddle matches today’s standard pinch width.
| Pinch width without paddle matches today’s standard pinch width.

• The Baseline® hydraulic pinch gauge uses the hydraulic system of the hand dynamometer to assure convenience, product reliability and measurement accuracy and repeatability.
• The therapist can support the pinch gauge during testing. This yields a more accurate result for all pinch tests including tip, key and palmer.
• The results are consistent with published Baseline® and Jamar® studies.
• Maximum reading remains until the unit is reset.
• The strength reading can be viewed as pounds or kilograms.
• Portable measuring unit comes with rugged carrying case.
• Easy adjustable paddle to accommodate to any size hand – other pinch gauges only have one pinch width.
• User can’t see results during testing.
• 5 pinch positions permits additional tests for tip, palmar and key tests.
• 5-position pinch test
• rapid exchange test
• pinch width without paddle is the same width as standard pinch gauge (mechanical and hydraulic).
• Can now provide same tests as 5-position hand dynamometers.
• 2-year manufacturers warranty.
• CE certified.

5-Position 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 further toward the tip the reading will be slightly higher.
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-index pulp pinch) – thumb tip to index fingertip
• Key Pinch (lateral pinch) – thumb pad to lateral aspect of middle phalanx of index finger
• Palmer Pinch (chuck pinch) – thumb pad to pads of the index and middle fingers
