Noble’s Test, also known as Noble’s Compression Test, is used to reproduce lateral knee symptoms associated with iliotibial band-related pain. A positive test may include familiar pain near the lateral femoral epicondyle during knee flexion and extension while compression is applied. High-quality diagnostic accuracy evidence for this exact test is limited, so the result should be interpreted with history, running/load behaviour, palpation, strength, movement quality and related findings.
A client with lateral knee pain may report symptoms during running, downhill walking, cycling, stairs or repeated knee flexion-extension. Noble’s Test can help assess whether compression over the lateral femoral epicondyle during knee movement reproduces familiar symptoms.
Recent reviews of iliotibial band syndrome highlight that the exact mechanisms of symptoms are still debated and may involve compression, tissue sensitivity, training load, hip-knee control and local tissue irritation. Noble’s Test may provide useful symptom reproduction information, but it should not be used as a stand-alone decision-making tool.
Test name: Noble’s Test
Also known as: Noble’s Compression Test
Purpose: Reproduce lateral knee symptoms during iliotibial band compression
Body region: Lateral knee
Commonly associated presentation: Iliotibial band-related lateral knee pain
Positive finding: Familiar lateral knee pain near the lateral femoral epicondyle during knee movement with compression
Negative finding: No familiar lateral knee pain reproduced
Best used with: Ober’s Test, running assessment, single-leg squat, hip strength testing, knee ROM, load history and palpation
Key limitation: Published diagnostic accuracy evidence for the exact test is limited
Noble’s Test is an orthopaedic test where pressure is applied near the lateral femoral epicondyle while the knee is moved through flexion and extension.
The test aims to reproduce symptoms associated with iliotibial band-related lateral knee pain. It does not identify the exact tissue source of pain on its own.
Noble’s Test is used when a client reports lateral knee pain that appears related to repeated knee flexion-extension activities. It can help document whether local compression and movement reproduce the client’s familiar symptoms.
The test assesses symptom response to compression over the lateral femoral epicondyle during knee movement.
It does not assess isolated iliotibial band length, hip strength, running mechanics, tissue structure or injury risk on its own.
This test may be useful for runners, cyclists, field sport athletes, hikers and clients with lateral knee pain during repeated loading tasks.
It may not be suitable when the knee is highly irritable, acute traumatic injury is suspected, swelling is marked, or the client cannot tolerate local compression.
Use this test when lateral knee symptoms and load history suggest iliotibial band-related pain may be relevant.
Use caution with acute trauma, severe pain, significant swelling, neurological symptoms, suspected fracture, locking, or symptoms that do not match a lateral overuse presentation.

Position the client supine or side-lying, depending on the preferred setup. The lateral knee should be accessible.
The tested leg is relaxed. The knee is flexed and extended passively during the test.
Stand beside the tested limb with access to the lateral femoral epicondyle.
Place the thumb or fingers over the lateral femoral epicondyle or the area of familiar symptoms. Use the other hand to control knee movement.
Stabilise the thigh and control the lower leg so movement is smooth and repeatable.
Apply firm but controlled pressure over the lateral femoral epicondyle while moving the knee from flexion toward extension and back through the symptomatic range.
Ask the client to report whether the test reproduces their familiar lateral knee pain.
A positive finding is reproduction of familiar lateral knee pain near the lateral femoral epicondyle during compression and knee movement.
A negative finding is no familiar lateral knee pain during the test.
Stop if pain escalates sharply, symptoms spread, the client guards strongly or the test is not tolerated.
Do not apply excessive pressure. Record the knee angle or range where symptoms occur.
A positive Noble’s Test may increase suspicion that lateral knee symptoms are related to iliotibial band-region sensitivity when it reproduces the client’s familiar pain and matches their activity history.
A negative test may reduce suspicion that local compression over the lateral femoral epicondyle is symptom-relevant during the tested movement, but it does not exclude iliotibial band-related pain, especially if symptoms occur only under running speed, fatigue or load.
Interpretation is stronger when combined with load history, palpation, running assessment, single-leg control, hip strength and symptom behaviour.
High-quality diagnostic accuracy evidence for Noble’s Test appears limited. Recent iliotibial band syndrome reviews discuss clinical presentation and assessment but do not provide robust sensitivity, specificity or likelihood ratios for Noble’s Test as a stand-alone test.
Because published values for this exact test and population are not well established, sensitivity, specificity and likelihood ratios should not be invented. The test is best interpreted as symptom reproduction information within a broader lateral knee assessment.
Reliability evidence for Noble’s Test is limited. Repeatability depends on consistent compression location, pressure, knee movement speed, knee angle and symptom criteria.
Validity is strongest when the test reproduces the client’s familiar lateral knee symptoms and aligns with their load history and related findings.
Common errors include pressing too broadly, failing to identify familiar symptoms, using inconsistent pressure, not recording knee angle, interpreting any lateral discomfort as positive and relying on the test alone.
Limitations include limited diagnostic accuracy evidence, pressure variability, symptom overlap with other lateral knee presentations and reduced transfer to dynamic activity.
Use Noble’s Test to document symptom reproduction, identify the knee angle range where symptoms occur, and guide whether further running, strength, mobility or load assessment is needed.
Record test name, side tested, result as positive, negative, unclear or unable to test, pain score, symptom location, symptom quality, compression site, knee angle where pain occurs, movement direction, comparison side, irritability, confidence in result, reason for stopping and related findings.
Recording these details improves repeatability, communication, client education, professional reasoning, monitoring over time and reporting quality.

Step-Down Test
Lateral Hop Test
It assesses whether compression near the lateral femoral epicondyle during knee movement reproduces familiar lateral knee symptoms.
A positive finding is familiar lateral knee pain during compression and knee flexion-extension.
No. It may support clinical reasoning but does not confirm a condition on its own.
High-quality diagnostic accuracy values for this exact test are limited.
Record pain location, compression site, knee angle, symptom quality, side tested and related movement findings.
Noble’s Test is a lateral knee symptom reproduction test.
A positive finding may increase suspicion of iliotibial band-region sensitivity.
Diagnostic accuracy evidence is limited.
The knee angle and symptom location should be recorded.
Use Measurz to track symptoms, test response and related findings.
