The McKenzie Institute® has supported research of and education about spinal and extremity disorders of the human musculoskeletal system since 1982. The McKenzie Method® of Mechanical Diagnosis and Therapy® is an active patient treatment philosophy that emphasizes prevention and intervention, and encourages patients to be in control of their own treatment. Its roots originated in the 1950s from the late Robin McKenzie, who over subsequent decades clinically tested and researched the phenomenon that became a highly effective, proven system of assessment, diagnosis and treatment of back and extremity pain. Using its thorough assessment and diagnostic process, certified MDT practitioners execute a total system of care based on sound principles and backed by extensive research. The McKenzie Institute Mission: Educate in and promote the principles of the management of musculoskeletal disorders as developed and described by Robin McKenzie.
