The McKenzie Method, also known as Mechanical Diagnosis and Therapy (MDT), is a structured, evidence-based approach to evaluating and treating spine and extremity pain. Developed by physical therapist Robin McKenzie, this method uses repeated movements and sustained positions to assess how your body responds-helping identify the specific mechanical cause of your pain rather than just treating symptoms. Learn how certain movements affect your pain, get specific exercises to manage your symptoms and improve your function to become self-sufficient. Assessment and treatment is provided by a credentialed physical therapist in Mechanical Diagnosis and Therapy.
