Which neural tension test is used to evaluate the radial nerve?

• A. Radial nerve tension test
• B. Median nerve tension test
• C. Ulnar nerve tension test
• D. Spurling's test

Answer: (A)

Neural tension tests are used to stress a specific peripheral nerve along its course to see if symptoms are reproduced, which helps identify irritation or entrapment of that nerve. The radial nerve tension test is the one that biases the radial nerve specifically, stressing it from the neck down to the hand. When performed, it positions the limb to place traction on the radial nerve; if familiar symptoms or paresthesias in the radial nerve distribution flare up, this supports radial nerve involvement.

The other tests target different nerves or regions: the median nerve tension test biases the median nerve, the ulnar nerve tension test biases the ulnar nerve, and Spurling’s test assesses cervical nerve roots for radiculopathy rather than a peripheral nerve. Therefore, the radial nerve tension test is the best choice for evaluating the radial nerve.
