As promulgated by The McKenzie Institute, USA, the McKenzie Method, also known as Mechanical Diagnosis and Therapy (MDT), is an evidence based assessment and management protocol for patients with spinal and extremity problems. The McKenzie Method utilizes a unique combination of postural and body mechanics training along with the application of specific individualized exercises which enables patients to self-manage their condition. MDT is applicable to acute, sub-acute, and chronic conditions.
