On December 5, 2010, Dr. Krebs of Chicago Spine + Sports successfully passed the credentialing exam for McKenzie Mechanical Diagnosis and Therapy. He is one of the first 65 doctors to complete the course work and pass this exam. McKenzie Mechanical Diagnosis and Therapy (MDT) is a systematic approach to the diagnosis and treatment of spinal related conditions. Research has shown the initial McKenzie assessment procedures to be as reliable as costly diagnostic imaging (i.e., x-rays, MRIs) to determine the source of the problem and quickly identify responders and non-responders. Unique to the McKenzie Method is a comprehensive and logical step-by-step process to evaluate the patient's problem quickly. This mechanical examination can "classify" most patient conditions by the level of pain or limitation that results from certain movements or positions. A McKenzie assessment can eliminate the need for expensive and/or invasive procedures. McKenzie treatment prescribes a series of individualized exercises. The emphasis is on active patient involvement, which minimizes the number of visits to the clinic.

Ultimately, most patients can successfully treat themselves when provided the necessary knowledge and tools. For patients with more difficult mechanical problems a hands-on approach is needed. By learning how to self-treat the current problem, patients gain hands-on knowledge on how to minimize the risk of recurrence and to rapidly deal with recurrence if it occurs. The likelihood of problems persisting can more likely be prevented through self-maintenance.
