Dynamometer

Also known as:  hand-held dynamometer, electronic hand grip dynamometer, measurement of grip strength.

What is a dynamometer?

A dynamometer is a medical instrument that is used to test grip strength. It primarily serves as a diagnostic and assessment tool. It is used when compromise of the cervical nerve roots or peripheral nerves is suspected. It can be used to measure progress after digital fractures or in someone who has arthritis, carpal tunnel syndrome or similar concerns. It can also be helpful assessing recovery in stroke patients and hand strength in older populations.


What happens during the test?

The patient is placed in a seated position, with the elbows bent at 90 degrees and the forearms in neutral. The arms are not supported by an armrest or other means during the test. The patient then exerts pressure on the handle of the dynamometer for a few seconds. He or she will then rest for about a minute and repeat the test a total of three times. The result of the test is the mean of the three attempts. The dynamometer measures the force exerted against it by the patient’s grip.


Is any special preparation needed?

No special preparation is needed for this test.


What are the risk factors?
