The principles of McKenzie Therapy are: 1. Reduce muscle stress by correcting faulty posture; 2. Increase blood flow and nutrient supply to the muscles through exercise. McKenzie therapy has a history of more than 50 years since its introduction, and it is a method of self-prevention of cervical and lumbar pain that has been proved to be very effective by medical practice in many countries. It has been widely used in hospitals for clinical rehabilitation of cervical and lumbar spine diseases. McKenzie therapy is an individualized treatment after clinical classification through patient assessment. Its two main features are the centripetalization phenomenon and self-adjustment therapy for postural correction. Of course, McKenzie therapy must be performed under the guidance of a professional doctor or rehabilitation therapist when treating cervical and lumbar spine disorders, in order to ensure the standardization of movements and avoid unnecessary injuries.
