Why Patient Low Back Pain Never Fully Resolves
Low back pain (LBP) remains one of the most common and persistent presentations encountered in clinical practice. Despite competent assessment and evidence-informed exercise prescription, many patients plateau or experience recurrent flare-ups.
In these cases, the issue is often not a lack of effort, knowledge, or exercise variety. Rather, it reflects the absence of a structured framework for identifying and interpreting movement dysfunction.
The Limitations of Isolated Findings in Low Back Pain Assessment
Most physiotherapists and allied healthcare practitioners are well trained in anatomy, tissue healing timelines, and orthopedic examination. However, a comprehensive core assessment is often reduced to isolated strength tests or observational cues without a unifying interpretive model.
Clinicians may identify rib flare, anterior pelvic tilt, breath-holding strategies, or delayed activation patterns, yet remain uncertain about how these findings interrelate or how they should guide treatment progression.
Without a framework, assessment becomes a collection of observations rather than a coherent clinical reasoning process. The practitioner may prescribe functional core exercises, adjust loading parameters, or provide increasingly specific cues.
While these interventions are not inherently incorrect, they may fail to address the underlying movement strategy that is perpetuating symptoms.
This gap in interpretation can contribute to prolonged or incomplete outcomes in chronic back pain treatment.
Understanding Core Dysfunction Beyond Strength
Core dysfunction is often conceptualized as weakness or poor endurance of the abdominal musculature. However, contemporary understanding emphasizes the integrated function of multiple systems, including:
-
The interaction between the inner and outer core unit
-
The coordination of the diaphragm and pelvic floor
-
Rib cage and pelvic alignment within dynamic tasks
-
Intra-abdominal pressure regulation and load transfer
Subtle alterations in rib cage positioning can influence pelvic mechanics and lumbar loading. Inefficient breathing strategies may reinforce suboptimal loading patterns and/or reduce the effectiveness of abdominal co-contraction. Patients may appear to perform core strength tests successfully, yet rely on compensatory strategies that maintain dysfunctional movement patterns.
In this context, the clinical question shifts from “Is the core strong?” to “How is the core functioning within the system, and what compensations are being used to achieve the task?”

The Value of a Structured Framework
A structured framework for low back pain assessment provides several key advantages:
-
Improved observational accuracy. Clinicians develop the ability to identify predictable compensation patterns, rather than interpreting findings in isolation.
-
Enhanced clinical reasoning. Observed movement strategies can be linked to anatomical, neuroanatomical, and biomechanical principles, clarifying why a patient presents the way they do.
-
Targeted intervention planning. Exercise prescription becomes progression-based and patient-specific, grounded in the individual’s movement strategy rather than generic “core strengthening.”
This approach reduces reliance on trial-and-error programming and increases confidence in clinical decision-making.
It also facilitates clearer communication with patients, since explanations can be tied directly to observable and meaningful findings.
The Deep Core Framework on Embodia
To address this gap between theoretical knowledge and clinical application, Julia Cetnar and Joelle Karam, of Physio Mentors, developed Low Back Pain: A Core-First Assessment & Treatment Approach, hosted on Embodia.
The course introduces The Deep Core Framework, a structured system designed to help practitioners assess and treat low back pain at its source.

The program integrates:
- A focused review of the anatomy and neuroanatomy of the core,
- Differentiation between the inner and outer core units,
- The functional roles of the diaphragm and pelvic floor,
- Identification of common compensation patterns, and
- Translation of assessment findings into targeted, functional core exercises.
Although low back pain serves as the primary clinical lens, the framework extends beyond lumbar presentations. Dysfunction within the deep core frequently influences shoulder instability, hip irritation, delayed post-operative progress, and other musculoskeletal complaints.
By understanding how trunk mechanics interact with the broader kinetic chain, clinicians can move beyond symptom-based treatment toward system-based intervention.
For practitioners seeking meaningful continuing education in physiotherapy, the goal is not to accumulate additional exercises, but to refine how patients are assessed and understood.
A structured framework for core assessment supports this shift, enabling more precise identification of dysfunction and more effective, individualized treatment planning.

Julia's academic journey began at the University of Western Ontario, where she graduated with an Honours Specialization in Kinesiology and a minor in Rehabilitation Science. Her lifelong involvement in athletics and interest in healthcare then led her to study physiotherapy at McMaster University. Julia is currently an instructor with the McMaster Contemporary Medical Acupuncture Program, Dr Mike Prebeg's Foundations in Functional Assessment course, and Dr Dan Wunderlich's Neurofunctional Acupuncture course. She is also an Adjunct Lecturer with the University of Toronto Physical Therapy Program, Vice President of the Canadian Contemporary Acupuncture Association, and editor of the Canadian Contemporary Medical Acupuncture Association's newsletter. She co-founded Physio Mentors with Joelle Karam and has enjoyed working closely with dozens of mentees over the past decade.
