Chiropractic BioPhysics (CBP)

What it is

Chiropractic BioPhysics is a technique discipline built on the premise that the normal spine has mathematically definable alignment parameters, and that deviations from those parameters contribute to pain, disability, and impaired nervous system function. CBP practitioners use a system called Harrison Spinal Coupling to identify how a patient's spine deviates from ideal alignment in all three planes of space: sagittal (side view), coronal (front-to-back), and axial (rotational). Those deviations are then addressed with a combination of chiropractic adjustment (spinal manipulation), mirror-image postural traction, and structured home exercise protocols that are each tailored to the direction of the patient's specific misalignment.

The word 'BioPhysics' reflects the technique's grounding in biomechanical engineering principles applied to the human spine. Normal cervical lordosis (the inward curve of the neck), thoracic kyphosis (the outward curve of the mid-back), and lumbar lordosis (the inward curve of the lower back) each fall within defined angular ranges, and CBP protocols are designed to restore curves that have flattened, reversed, or shifted laterally. Conditions like Tech Neck, which often flatten or reverse the cervical curve over years of screen use, represent exactly the kind of postural pathology CBP was designed to address. Because the technique uses radiographic measurement at intake and at defined intervals during care, progress is documented objectively rather than estimated from symptom reports alone.

What to expect

A CBP case begins with a detailed postural examination and, typically, digital X-rays taken in weight-bearing posture. The images are analyzed to measure spinal curvatures, vertebral translations, and the overall alignment of the head and pelvis relative to the gravity line. Those measurements establish the patient's baseline and define the specific geometric corrections the care plan will pursue. Patients are shown their own images and the clinical targets so that the goals of care are transparent from the first visit.

Active treatment sessions combine the chiropractic adjustment, mirror-image spinal traction (positioning the spine in the opposite direction of its distortion while gentle force is applied), and rehabilitative exercises prescribed to retrain spinal musculature into corrected posture. Mirror-image traction is typically performed on a drop table or traction unit and held for several minutes per session. Home exercise protocols reinforce the in-office work and accelerate the remodeling of spinal ligaments and discs. Progress radiographs are taken at intervals specified by the CBP protocol, allowing to confirm measurable structural change and adjust the care plan accordingly. Patients dealing with Posture Correction goals generally find the measurement-based format motivating because it converts abstract improvement into documented, visible change.

Key benefits

• CBP produces objectively measurable changes in spinal alignment because outcomes are tracked radiographically rather than by symptom rating alone. ^[1]
• Mirror-image postural traction, when combined with chiropractic adjustment, targets the ligamentous and discogenic structures that resist correction over time, producing structural changes that outlast in-office sessions. ^[2]
• The technique's mathematical alignment targets give both the clinician and the patient a clear, agreed-upon endpoint for care, reducing ambiguity about when meaningful correction has been achieved. ^[3]
• CBP's structured exercise component addresses spinal muscle imbalances that perpetuate postural distortion, making the technique relevant for patients whose alignment problems stem partly from neuromuscular dysfunction. ^[5]
• Because CBP protocols identify and treat three-dimensional spinal deformity, the technique applies to conditions as varied as cervical hypolordosis (loss of normal neck curve), lateral translations, and mild scoliosis curves detected early. ^[7]

Who benefits most

Patients who benefit most from CBP are those whose spinal problems have a structural, geometric component rather than being purely muscular or acute in nature. This includes adults who have developed forward head posture from years of desk work or device use, patients whose imaging shows reversed or flattened spinal curves, and individuals who have tried symptom-focused care without achieving lasting results. Because CBP sets measurable targets and tracks progress against them, it suits patients who prefer data-driven explanations and want to understand the mechanism behind their care plan. ^[1]

How it connects to chiropractic

CBP sits at the intersection of clinical chiropractic practice and biomechanical engineering, and that combination is what distinguishes it from technique systems focused primarily on joint mobilization. The chiropractic adjustment in a CBP protocol is directionally specific: force vectors, patient positioning, and table drop settings are all chosen to move the spine toward its mathematical target, not simply to restore segmental motion. Research examining the neurophysiological effects of chiropractic care helps explain why this precision matters. Studies have demonstrated that chiropractic interventions alter sensorimotor integration, meaning the brain's ability to process and regulate body position and muscle activity, through mechanisms that go beyond simple joint cavitation. ^[4] When spinal geometry is persistently abnormal, those sensorimotor signals are chronically distorted, and CBP's structural correction approach addresses the source of that distortion rather than just its downstream effects.

The traction and exercise components of CBP exploit a well-established property of connective tissue: creep and stress relaxation in viscoelastic (time- and load-dependent) structures like spinal ligaments and intervertebral discs. Sustained low-load forces applied in the mirror-image direction allow those tissues to lengthen and remodel incrementally over a course of care. This is why CBP protocols specify hold times during traction, typically measured in minutes, rather than brief impulse forces alone. The rehabilitative exercises that accompany traction train spinal stabilizers to actively maintain the corrected position, reducing the tendency of ingrained postural patterns to pull the spine back toward its prior alignment. ^[6] For patients whose posture correction goals include the cervical spine, this combination is particularly relevant because the cervical curve is the region most commonly flattened or reversed by forward head loading.

CBP's relevance to tech neck and screen-related postural decline is well-supported by its measurement framework. The technique can quantify how much anterior head translation a patient carries, track regression or improvement over care, and correlate structural findings with symptom patterns. Outcomes research in chiropractic has consistently called for measurement-based frameworks that connect structural findings to functional outcomes, and CBP was designed with exactly that demand in mind. ^[1] At, CBP is integrated with when disc involvement accompanies postural distortion, and the technique pairs naturally with that address soft-tissue components alongside structural correction. Patients interested in understanding how their care plan is structured are encouraged to review the background on's 28 years of clinical experience. Evidence from trials examining chiropractic care's effects on physiological biomarkers suggests that structural correction influences systemic outcomes beyond mechanical alignment alone, a finding that reinforces the CBP premise that spinal geometry matters for overall health, not just pain levels. ^[5] The Pettibon System, described on the Pettibon System page, shares some rehabilitative exercise concepts with CBP but uses different analytical geometry and traction protocols, so patients who have encountered both names will find meaningful clinical distinctions between them. Across all CBP care, the constant is documentation: intake imaging, interim imaging, and discharge imaging that creates an auditable record of structural change. ^[7]
