Definition/Description[edit | edit source]

The Noble’s test (also known as Noble's Compression test) is a provocative test of the iliotibial band, developed by Clive Noble. It is commonly used as an indication for iliotibial band syndrome; however, no evidence-based research has been done yet to control the validity of this test. Other tests that could be used are the modified Ober’s test and the Renne Creak test[1][2][3]

Clinically Relevant Anatomy[edit | edit source]

Relevant anatomy related to the test is knowledge of the iliotibial band. It starts as the iliotibial tract, which is a thickening of the fascia lata, originating from the iliac crest. The iliotibial tract continues downward, laterally from the femur. At the greater trochanter, fibres of the tensor fascia lata muscle and gluteus maximus muscle inserts in the iliotibial tract. When approaching the knee joint, the iliotibial tract passes the lateral epicondyle of the femur and splits into two structures: the iliopatellar band, and a distal extension inserting at the Gerdy tubercle (Figure 1).[4]

During walking and running, the Iliotibial band is subjected to frictional and compressive forces over the greater trochanter and lateral epicondyle. Repetitive strain, improper footwear, lower extremity mal-alignments and muscle imbalance results into increased friction.[5]

Iliotibial band (ITB) friction syndrome is an overuse injury common in runners, cyclists, weightlifters, skiers, and soccer players. It is characterized by pain over the lateral femoral epicondyle caused by excessive friction between the ITB and the lateral femoral epicondyle.

Purpose[edit | edit source]

The purpose of this test is to detect pain, abnormalities, tightness of the iliotibial tract, which can be indicative for the iliotibial band syndrome. It helps to differentiate iliotibial band syndrome from other common causes of lateral knee pain.[2][4]

Technique[edit | edit source]

Put the patient in a supine position. Next, bring the affected knee up to a 90-degree knee flexion and apply pressure with your thumb to the lateral femoral epicondyle. The leg is then extended slowly. When it is extended to approximately 30 degrees, the iliotibial band translates anteriorly over the lateral femoral epicondyle under the examiner's thumb.

If the patient indicates pain at this 30-degree angle, which is similar to when the patient is active, the test is considered positive and it suggests the presence of iliotibial band syndrome.

Evidence[edit | edit source]

Reliability & Validity: Unknown[7]

Clinical Bottom Line[edit | edit source]

This test is indicative of iliotibial band syndrome, but again it must be stated that there have been no studies to indicate the validity of this test.[2][4]
