What it means
With the client on the back, the examiner bends the right hip and knee to 90 degrees and turns the lower leg outward, which rotates the hip inward and stretches the obturator internus muscle in the pelvis. Pain is a positive sign. It suggests an inflamed appendix or abscess lying low in the pelvis against that muscle.
