Overview
This lecture explains the Ober’s Test, a physical assessment for contracture (tightness) of the tensor fascia latae muscle and the iliotibial band.
Purpose of the Ober’s Test
- The Ober’s Test checks for tightness in the tensor fascia latae, which can cause a tight iliotibial (IT) band.
- It is used to assess muscle contractures affecting hip mobility.
Performing the Ober’s Test
- Place the patient in a side-lying position with the lower leg flexed at the hip and knee for stability.
- The examiner passively abducts the upper leg and brings it into slight extension.
- One hand of the examiner should fixate the pelvis to prevent movement.
- The upper leg can be kept fully extended for a more intense stretch of the IT band (though originally described at 90° knee flexion).
- Slowly lower the upper leg toward the table.
Interpreting Results
- The test is positive if the upper (tested) leg stays elevated and does not touch the table, indicating tightness.
- A negative test occurs if the upper leg falls completely down to the table (no tightness).
Key Terms & Definitions
- Ober’s Test — a physical assessment to detect contracture of the tensor fascia latae and tightness of the IT band.
- Tensor Fascia Latae — a muscle of the thigh involved in hip abduction and stabilization.
- Iliotibial (IT) Band — a thick band of connective tissue running along the outside of the thigh from hip to knee.
- Contracture — permanent shortening or tightness of a muscle or tendon causing restricted movement.
Action Items / Next Steps
- Review the Ober’s Test procedure steps and practice on a peer.
