Sn = 0.76 for all patients (Higher Sn when just looking at patients with severe symptoms) Sn = 0.86 for patients with any difficulty with [Active Straight Leg Raise Test] and [Sacral Thrust Test] Sn = 0.98 for patients with at least somewhat to fair difficulty with [Active Straight Leg Raise Test] and [Sacral Thrust Test] N=178 with peripartum pelvic pain. Ask the patient to raise their leg keeping the knee extended 3. Passively flex the patient's hip, but this time with the ipsilateral knee flexed to end-range. 95. ...
