The document summarizes assessment and treatment techniques for sacroiliac joint dysfunction, including muscle energy techniques. It describes tests like the prone lying, sphinx, and hypersphinx positions to assess sacral positions. Treatment involves techniques to correct unilateral sacral flexion or torsion, like medial rotation or trunk rotation against resistance. Specific protocols are outlined for addressing forward or backward sacral torsion. Rotated innominate dysfunctions are also addressed using resisted hip motions in various positions.
