Our Approach

The McKenzie Method (MDT)
for Spine and Musculoskeletal Pain

Mechanical Diagnosis and Therapy (MDT), also known as the McKenzie Method, is an internationally recognized, evidence-based system for assessing and treating spine and musculoskeletal conditions. Rather than relying on imaging findings or symptom location alone, MDT guides treatment based on how your body responds to movement.

The Right Treatment Starts
with the Right Assessment

When pain keeps returning—or never fully resolves—the problem isn't always that treatment failed. Sometimes the mechanical source of the pain simply hasn't been accurately identified. That's why some people discover Mechanical Diagnosis and Therapy (MDT) after trying other approaches, while others seek it from the very beginning.

MDT is a structured assessment system that evaluates how your symptoms respond to repeated movements and sustained positions to identify the mechanical source of pain. Rather than relying solely on imaging findings, symptom location, or a diagnosis alone, treatment is guided by your body's individual response.

Although best known for treating back and neck pain, MDT is also an effective assessment system for many shoulder, hip, knee, ankle, and other extremity conditions when mechanical factors contribute to symptoms.

"Most people with back pain have never been given a real mechanical diagnosis. They've been given a label — and sent to generic exercises."

Find the Source, Not Just the Symptom

MDT begins with a comprehensive mechanical assessment — a systematic movement-based evaluation that identifies exactly what structure is generating your pain and why. You leave your first session with an understanding of what may be causing your pain, often for the first time.

02

Classify the Problem

MDT assigns your pain to one of three mechanical syndromes — Derangement, Dysfunction, or Postural — each with a distinct treatment approach. This classification is what separates MDT from generic PT: treatment is targeted, not generic.

03

Empower You to Treat Yourself

The explicit goal of MDT is patient independence. You'll leave each session with a clear home program and the knowledge to apply it. Most patients can manage future flare-ups on their own — without returning to the clinic.

04

Fewer Visits, Durable Results

Because MDT addresses root causes, most patients complete care in 4–8 visits — significantly fewer than conventional PT. Better outcomes, in less time, with the skills to stay well.

The Value of a Thorough Assessment

Clarity, regardless
of the outcome.

One of the greatest strengths of Mechanical Diagnosis and Therapy (MDT) is that it helps determine who is—and isn't—likely to benefit from this approach. If your symptoms respond mechanically, MDT provides a clear direction for treatment. If they don't, the assessment helps identify that early, allowing treatment to be redirected rather than continuing an approach that isn't producing meaningful results.

In other words, the evaluation is valuable regardless of the outcome. Whether it confirms that MDT is the right approach or points toward a different path, the goal is the same: to provide clarity and guide the most appropriate next step in your recovery.
