A pelvic block or sacroiliac joint block is a concept from alternative medicine ( manual medicine , osteopathy , Dorn therapy ). According to the advocates of these methods, the joints between the sacrum and the two iliac bones , the sacrum and iliac joints ( sacroiliac joints , SIJ), are "blocked" , that is, not or not fully mobile. Triggers are falls, bumps or increased mobility due to loose ligaments . This should have the consequence that the pelvis is "crooked". This also affects the surrounding joints by limiting the mobility of the facet joints of the lumbar spine , which have to compensate for this misalignment. Since these vertebrae are then unable to perform their physiological function correctly, symptoms can arise there. This blockage is also described in alternative equine medicine. In the opinion of the representatives, up to 80% of riding horses suffer from a sacroiliac joint blockage, which usually already occurs in foal age.

The elasticity and mobility of the sacrum and iliac joints are examined using a spring test and palpation in the prone position. The thumb is placed on the sacrum and the index finger on the pelvis and the nutation and counter- nutation as well as extension and flexion are checked. Displacements and a horizontal internal or external rotation can thus be demonstrated. The symmetry of the pelvis is assessed using the spines of the iliac bone.

The pelvis can be mobilized as a measure against a pelvic blockage. A counter-nutation is triggered by pressing in opposite directions with both thumbs, one on the ilium and the other on the sacrum. Alternatively, the bent and slightly adducted leg can be pushed in the supine position towards the base. In Dorn therapy, slides are also used to resolve a sacroiliac joint blockage.
