For chiropractors practicing today, Dr. Warren Hammer’s legacy is particularly visible in several areas that have become familiar components of modern musculoskeletal care: his early work with the Graston Technique and instrument-assisted soft-tissue mobilization; his extensive writing and teaching on functional soft-tissue examination and treatment; his role in bringing fascial manipulation to U.S. clinicians; and his decades spent educating chiropractors and other health professionals.
