PSAST: Pelvis-Stabilized Axial Spinal Traction

 

What is PSAST?

Pelvis-Stabilized Axial Spinal Traction (PSAST) is a specialized, linear spinal decompression technique. By stabilizing the pelvis, we are able to apply a controlled, longitudinal force along the body’s vertical axis—from the vertex of the head to the tailbone.

Unlike traditional traction methods, PSAST is non-rotational, meaning it avoids twisting or torquing the cervical spine. This stabilization ensures the decompression is uniform, safe, and effective for the entire central nervous system.

 

The Science: Why PSAST is Different

Our practice is built on emerging clinical evidence regarding the relationship between spinal mechanics and neurological health. We utilize findings from two landmark papers to guide our PSAST sessions:

1. Sustaining Vital Function: A 21-month clinical report documented the use of axial spinal traction in a patient with bulbar-onset ALS. The study showed sustained respiratory and bulbar (speech and swallowing) function, suggesting that PSAST may help maintain quality of life in neurodegenerative conditions.

2. Brain "Waste Clearance": A biomechanical technical report hypothesizes that axial traction acts as a modulator of the glymphatic system. By optimizing the "pulse" and circulation of cerebrospinal fluid (CSF), PSAST may help the brain more efficiently clear metabolic waste.

 

What are the Benefits?

• Neuro-Supportive: Supports spinal function and fluid circulation in patients with neurological disorders (such as ALS).

• Enhanced Glymphatic Flow: Assists in the "pumping" of cerebrospinal fluid to support the brain’s natural detoxification process.

• True Axial Decompression: By stabilizing the pelvis, we maximize the increase of intervertebral disc space and reduce nerve root compression more effectively than non-stabilized methods.

• Systemic Relief: Alleviates chronic headaches, neck stiffness, and upper back tension by releasing "stuck" spinal segments.

 

Is PSAST Safe?

Yes. When performed by a professionally trained doctor, Pelvis-Stabilized Axial Spinal Traction is safe and highly controlled.

We use specialized equipment—including a precision cervical harness, stabilizing pads, and pelvic anchors—to keep your spine in the correct alignment. The doctor adjusts the force based on your specific condition and monitors your response throughout the session.

 

What Does It Feel Like?

• Typical Sensations: You may hear a "pop" or "click" sound, which is a natural release of joint pressure. Many patients describe an immediate feeling of "elongation" or a significant "lightness" from the neck down to the lower back.

• Common Reactions: Post-session, patients often report deep relaxation or a temporary "heavy" feeling in the limbs, which is a sign of the nervous system shifting into a restorative, parasympathetic state.

 

Addressing Your Concerns

What if I feel nervous? It is completely normal to feel apprehensive before your first session. We utilize a Graduated Loading protocol, beginning with a very light force to let you experience the movement gently.

Who should consult a doctor before treatment? While PSAST is beneficial for many, a clinical evaluation is required for:

• Patients with severe osteoporosis.

• Recent spinal surgery or acute traumatic injury.

• Uncontrolled hypertension.

• Certain central nervous system disorders (we will review your history during your consultation).
