Maudsley’s Test: Interpreting Resisted Middle Finger Extension

What does Maudsley’s test involve?

Maudsley’s test uses resisted middle finger extension to explore lateral elbow or proximal forearm symptoms. A commonly taught version uses a pronated forearm and extended elbow while the examiner resists extension at the finger’s metacarpophalangeal joint.

Support the limb, explain the task and apply resistance gradually. Ask whether the response reproduces the client’s familiar complaint. Pain in the finger joint itself is a different finding from the elbow or forearm pain being investigated.

Why can a finger movement provoke elbow pain?

The finger extensors connect with structures in the proximal forearm. Fairbank and Corlett’s anatomical and clinical work suggested a role for extensor digitorum communis in the response to this test.[1] It should not be described as an isolated test of extensor carpi radialis brevis.

A useful client explanation is that muscles moving the fingers have connections near the elbow. There is no need to suggest the test has exposed a damaged tendon or trapped nerve.

Tennis elbow or radial tunnel syndrome?

Maudsley’s test appears in descriptions of both conditions. A critical review highlighted uncertainty about its clinical validity and anatomical rationale, particularly for radial tunnel syndrome.[2] A positive result cannot reliably distinguish between them.

Ask the client to point to the response. Is it near the lateral epicondyle, further down the proximal forearm or elsewhere? Location helps guide further assessment, but it is not a precise diagnostic boundary.

For instance, a client with familiar epicondyle pain during lifting presents differently from someone describing a deeper forearm ache during tool use. Even if both have a painful test, their histories should lead to different follow-up questions.

When the result is unclear

Consider what the test adds. Collecting several painful responses does not automatically make a diagnosis more certain. A negative response simply means this task did not reproduce symptoms under the conditions used.

For massage and other manual therapists, an uncertain presentation may justify referral. Progressive weakness, difficulty extending the fingers or persistent sensory changes deserve broader assessment rather than repeated provocative testing.

Document the observation

Record the position, pain location, familiarity and settling time. For example: “Resisted middle finger extension reproduced familiar lateral elbow pain; symptoms settled on release.” This communicates the finding without overstating what it proves.

If the response improves after treatment, check whether a meaningful activity has also improved. Immediate comfort during retesting does not demonstrate nerve decompression or structural correction.
