Manual palpation of lumbo-pelvic landmarks: a validity study.

Manual palpation (MP) is commonly used for the assessment of patients with neuromusculoskeletal dysfunction. During assessment of lumbo-pelvic disorders in particular, it may be used not only to explore pain and resistance in the region, but also to evaluate the symmetry and movement quality of the area. Whilst reliability of MP has been extensively investigated, its validity remains relatively under researched.
