Log Roll Test

August 21st, 2017


The log roll test assesses for pathology within the hip joint, and can be used to isolate the patient's pathology to the hip as opposed to outside of the hip joint.
  • How to Perform

  • With the patient in a supine position, place one hand over the mid-thigh and passively externally and internally rotate the hip to the ends of its range of motion. Compare the range of motion on both sides.
  • Abnormal If

  • Pain - intra-articular pathology.
  • Clicking - acetabular labral tear.
  • Increased range of motion - ligamentous laxity.
The log roll is the single most specific test for hip pain. It moves the articular surface of the femoral head in relation to the acetabulum, with minimal stress on surrounding muscle or nerve.
