- Duration
- Acute Triage (Weeks 1-3) | Structural Remodeling (Weeks 4-8)
- Frequency
- Intervention selection and visit cadence arise directly from live physical exam findings, never from a pre-printed accident template.
- Equipment
- Specialized Cox® Flexion-Distraction Table, Spinographic Vector Mapping, EMG/Nerve Conduction, Surface Cryotherapy, Active PT Stabilization Tools.
- 1.1. Exam-First Baseline Triage (Episode 111)We map live movement catching, acute tissue irritability indices, multi-planar active ROM degrees, and dermatomal/myotomal neuro screens before choosing any treatment.
- 2.2. Hands-On Certified Cox® Flexion-DistractionDr. Sta. Juana manually guides rhythmic axial traction on the Cox® table, dropping intradiscal pressure to -192 mmHg and expanding the spinal canal by 28% while sensing muscle guarding in real time.
- 3.3. Immediate Post-Decompression Retest & PT Window (Episode 112)We retest joint range immediately after table distraction to verify the structural shift, then leverage the temporary relief window to launch active PT loading with Liza Sta. Juana, PT.

A Clinical Distinction on the US Southern Border
When a high-velocity motor vehicle collision on 10th Street, Bicentennial Boulevard, or Expressway 83 in McAllen, Texas results in severe whiplash, an extruded L5-S1 disc, or crippling sciatica, patients are faced with a crucial decision. Most local clinics offer standard "crack-and-pop" chiropractic or strap patients onto automated motorized traction tables.
Dr. Paul Sta. Juana, DC holds a unique clinical distinction: he is the ONLY certified Cox® Technic practitioner on the entire Southern Border of the United States.
What It Means to Be the Region's Sole Certified Cox® Specialist
Certified Cox® Flexion-Distraction is an advanced post-doctoral discipline that requires years of specialized training in spinal biomechanics, neuro-pathology, and manual decompression. For McAllen and Rio Grande Valley residents, this means accessing world-class, research-backed disc reconstruction locally—without traveling to Dallas, Houston, or San Antonio.
Cox® Flexion-Distraction vs. Automated Mechanical Decompression
Patients often ask: "How is certified Cox® Technic different from those automated decompression tables where you lie down and a computer pulls you?"
The difference comes down to tactile feedback, micro-vector control, and safety. Automated mechanical tables strap a patient into a harness and rely on a blind electric motor pulling on a pre-set timer. If the patient's spinal muscles begin to spasm or guard during a mechanical pull, the machine cannot feel it—it keeps pulling, which can trigger reactive muscle splinting or worsen disc inflammation.
Episode 111 Master Concept: "Treatment Should Follow Findings"
A foundational error in personal injury care is applying a pre-printed "collision package" to every accident victim. Assuming a treatment plan is completely obvious simply because a patient was in a car crash represents an administrative failure.
"The treatment should not be chosen before the exam is finished. If you already know the plan before testing the patient, that is not clinical reasoning. The crash gives us context, but the exam gives us direction. Most systems ask, 'What treatment do you do for accident patients?'; better care asks, 'What did this patient's exam show?' Test first. Treat second."
At South Texas Accident & Injury, our diagnostic triage maps multiple adaptive layers before selecting any intervention:
- Collision Force Kinematics: Analyzing impact vectors (rear-end, T-bone, rollover) and occupant positioning.
- Acute Tissue Irritability Indices: Quantifying inflammatory thresholds to determine safe loading depths.
- Multi-Planar Active ROM Degrees: Measuring exact degrees of restriction and painful motion catching.
- Upper & Lower Quarter Neuro Screens: Pinpointing dermatomal numbness, myotomal motor weakness, and reflex deficits.
- Immediate Retest Verification: Running an objective retest right on the clinical floor immediately after treatment to confirm the structural shift.
Episode 112 Master Concept: "Adjustments & Decompression Are Not the Whole PI Plan"
Spinal manipulation and Cox® decompression are invaluable mechanical tools—they reduce acute pain, modulate nociception, and temporarily open restricted motion windows. However, allowing on-table table relief to become the entire clinical identity of a trauma file is a severe mistake.
"Adjustments and decompression are not the whole PI plan. Relief on the table does not prove recovery in real life. Most people notice the table treatment; better care asks what the treatment is helping the patient do next. The question is not, 'Did it pop?' or 'Did it stretch?'; the question is, 'What changed after?' Use the treatment as a tool, not a finish line."
This is where our multidisciplinary DC + PT model changes the trajectory of your recovery. When Dr. Paul Sta. Juana, DC performs certified Cox® decompression, it lowers intradiscal pressure and creates a 15-to-30-minute biological window of pain relief and joint mobility.
Instead of sending you out the door, Liza Sta. Juana, PT immediately steps in to utilize that open mobility window—guiding you through active motor control drills, myotomal strength loading, and core ligament stabilization. Relief on the table opens the door; active rehabilitation builds the permanent solution.

Frequently Asked Questions
Where is your clinic located relative to McAllen?
Our central facility is at 505 W Business Hwy 83 Ste 7 in Alamo, TX—just minutes down Interstate 2 / Hwy 83 from McAllen. McAllen residents choose us to access the Southern Border's only certified Cox® Technic practitioner and avoid crowded volume-based clinics.
Why is hands-on Cox® Technic safer than automated decompression after a crash?
Automated traction tables pull blindly using an electric motor. If acute whiplash or a severe disc herniation triggers muscle spasms, a machine cannot feel it and will pull against guarding muscles. In certified Cox® Technic, Dr. Sta. Juana keeps his hands on your spine during the entire decompression movement, micro-adjusting tension and stopping instantly if guarding occurs.
What does "Test First. Treat Second" mean for my accident claim?
It means we do not give you a generic, pre-printed treatment plan. We perform thorough physical, neurological, and range-of-motion testing first. Every treatment and active exercise is selected based on what your exam showed. This produces bulletproof, evidence-backed medical records that protect your health and your legal claim.
