The effects of experience on the inter-reliability of osteopaths to detect changes in posterior superior iliac spine levels using a hidden heel wedge.

Background: The use of palpation to diagnose musculoskeletal dysfunction is commonly taught within osteopathy and other manual therapies. However the clinical tests used to detect sacroiliac joint dysfunction have not shown good reliability.

Objectives: To investigate the inter-examiner reliability of osteopaths to detect asymmetries of the posterior superior iliac spine (PSIS), and to determine if inter-examiner reliability was affected by the level of practitioner experience.
