Pinch Grip Testing

A pinch grip is a form of precision grip for individuals to perform activities of daily living and various everyday tasks. Pinch grip strength testing provides valuable information to understand impairments and functional limitations a patient may be experiencing. 

There are three standard pinch strength tests that are commonly performed by physical therapists, occupational therapists and other medical professionals. 

1. Lateral pinch (key pinch): Place the the pinch dynamometer between the radial side of the index finger and thumb, and have the patient pinch as hard as possible.
2. Three -point pinch (three jaw chuck pinch): Place the pinch dynamometer between the pulp of the thumb and pulp of the index and middle fingers, and have the patient pinch as hard as possible.
3. Two-point pinch (tip to tip pinch): Place the pinch dynamometer between the tip of the thumb and the tip of the index finder, and have the patient pinch as hard as possible. 

The muscle that are involved in these pinch tests are the adductor policies, 1st dorsal interossie, and flexor policies brevis. Each test should be repeated three times and then an average should be calculated for each of the three tests. 

Rehab Therapy Supplies carries a number of pinch dynamometers (pinch gauges) to perform pinch grip testing.

One of the pinch dynamometers that we carry is the Baseline, BIMS, Digital 5-Postion Pinch Dynamometer. This pinch dynamometer comes in three different models: 

1. Baseline, BIMS, Digital 5-Postion Pinch Dynamometer, Clinci Model
2. Baseline, BIMS, Digital 5-Postion Pinch Dynamometer, Deluxe Model
3. Baseline, BIMS, Digital 5-Postion Pinch Dynamometer, Functional Model

These three models of pinch dynamometers represent the latest and greatest  technology applied to a familiar product. This particular product has the new load-cell digital technology. A more accurate, repeatable, and consistent measurement mechanic compared to the standard hydraulic dynamometer. Each dynamometer features adjustable 5-position paddles that fits all hand sizes and enables testing at various grip positions. Simple and easy to use, just press select to begin and delete to reset the test to zero.
