The Pinch Grip Strength is a wrist examination procedure that assesses muscle weakness. Weakness of the anterior neuropathy which is a deep branch of the median nerve, can be diagnosed with the use of the Pinch Grip Strength test.
There are many ways to test for pinch and grip of an afflicted hand and in all the possible tests, the non-dominant or the unafflicted hand serves as control.
The patient should be awake and cooperative when a Pinch Grip Strength test is done.
- Patient may be seated or standing while performing the test.
- Tell the patient to pinch the index finger and the thumb together making a tip-to-tip contact.
- Examiner applies muscle resistance or he may use a pinch grip gauge. The patient squeezes the pinch grip gauge.
- Take note of any weakness or poor muscle resistance.
Positive Pinch Grip Strength Test
There is positive Pinch Grip Strength when there is observed muscle weakness or the patient uses a pad-to-pad (not tip-to-tip) response in pinching the index finger and thumb together. These could indicate neuropathy of the anterior interosseous.
To further examine peripheral neuropathies, nerve conduction velocity (NCV) testing should be done.
