Ober's test
Ober's Test
Ober's test (/ˈoʊbərz tɛst/; named after the American orthopedic surgeon, Frank R. Ober) is a medical examination used to assess the tightness of the iliotibial band, a ligament that runs along the outside of the thigh, from the hip to the shin.
Etymology
The test is named after its developer, Frank R. Ober, an American orthopedic surgeon who first described the procedure in 1935.
Procedure
The patient lies on their side with the affected leg uppermost. The examiner then passively abducts and extends the patient's hip while the knee is flexed at 90 degrees. The hip is then allowed to drop into adduction. If the hip remains abducted, the test is positive, indicating tightness of the iliotibial band.
