What Is a Bernstein Test?

A Bernstein Test is a type of clinical test used to diagnose bone and joint diseases, such as arthritis. The test was first developed by Dr. Samuel D. Bernstein in 1954. It involves the use of a hand-held machine to place localized pressure on specific joint surfaces and measure the amount of pain that is experienced.

Why Is a Bernstein Test Performed?

The Bernstein Test is performed mainly for diagnostic purposes. It can determine the extent and severity of arthritis, rheumatoid arthritis, or any other type of chronic joint disorder. Also, it can help doctors pinpoint which joints are affected and to what extent.

When Is a Bernstein Test Usually Prescribed?

A Bernstein Test is usually recommended when other tests such as x-rays, MRI scans, or laboratory tests don’t give a clear picture of the joint disorder. Additionally, the test can help evaluate why joint pain is getting worse. It can also rule out other causes of joint pain such as tendinitis, bursitis, or gout.

Preparation for a Bernstein Test

When preparing for a Bernstein Test, a patient should wear loose clothing that will not restrict the movement of the joints being tested. The patient should also be aware of any medications or supplements they are taking to make sure that they are not contraindicated for the test. Lastly, the patient should make sure the physician is aware of any medical conditions that they have that could interfere with the procedure.

Procedure for a Bernstein Test

The procedure for a Bernstein Test usually begins with the physician feeling the area around the joint before the test. Once the area has been identified, the patient will be asked to lie on their back on the examination bed. The device will then be placed directly on the joint area that needs to be tested. Pressure will be applied and the patient will be asked to describe the level of pain they feel. The pressure will then be released and the physician can compare the before and after results. Multiple areas of the joint may be tested if necessary.

Types of Bernstein Tests

There are three types of Bernstein tests: the Single-Point Bernstein Test, the Multiple-Point Bernstein Test, and the Reversal Bernstein Test. In the Single-Point Bernstein test, only one area is tested. The Multiple-Point Bernstein Test tests multiple areas of the joint to gather more precise information. Lastly, the Reversal Bernstein Test is also used to test multiple areas but an increased pressure is used to gather additional data.

Potential Risks of a Bernstein Test

There are few potential risks involved with a Bernstein Test – the risk of over-diagnosing and the risk of trauma to the joint. Over-diagnosing can occur if the patient is not accurately describing the level of pain or if the physician is interpreting the results incorrectly. The risk of trauma to the joint is minimal, but there could be some pain or discomfort during or after the procedure.
