Spinal Decompression

What it is

Spinal decompression is a form of motorized traction delivered through a computer-controlled table that applies precise, intermittent distraction forces to specific spinal segments. The term 'decompression' refers to a measurable reduction in intradiscal pressure, the load carried by the nucleus pulposus (the gel-like inner core of an intervertebral disc). When that pressure drops below a critical threshold, a retraction force is created that can draw herniated or bulging disc material back toward the disc's center, reduce mechanical irritation on nearby nerve roots, and support the diffusion of nutrients into disc tissue that is otherwise poorly vascularized. ^[5]

The procedure is distinct from simple traction tables used in earlier decades. Modern decompression units monitor patient response in real time and modulate the pull to prevent the paraspinal muscles (the muscles running parallel to the spine) from guarding or contracting reflexively, which would reduce therapeutic effect. Treatment is performed fully clothed, with the patient lying supine or prone on the table depending on the segment being addressed. Sessions typically run between fifteen and thirty minutes. The lumbosacral spine, where Low Back Pain and disc pathology are most prevalent, is the primary target, though cervical decompression protocols address the neck with a separate harness configuration. ^[8]

What to expect

An initial consultation at Moss Chiropractic of Inverness includes a clinical history, orthopedic and neurological examination, and review of any available imaging before a decompression protocol is designed. Candidates who have active fracture, spinal instability, advanced osteoporosis, or certain vascular conditions are not appropriate for mechanical decompression, and that screening happens before the first session. For those who are appropriate candidates, the first treatment is performed at a reduced distraction force to establish tolerance. Most patients describe the sensation during a session as a gentle, rhythmic stretch rather than pain.

A typical course of care spans several weeks, with multiple sessions per week during the initial phase. Clinical outcomes in trials studying non-surgical spinal care for disc-related conditions show that improvement in pain and disability often appears within the first few weeks, though tissue remodeling continues beyond symptom relief. ^[7] Dr. Brett A. Moss frequently pairs decompression sessions with a chiropractic adjustment to restore segmental joint motion, and with corrective exercise to build the muscular support structures that protect the disc long after active treatment ends. Some patients also receive as an adjunct to address soft-tissue inflammation around the decompressed segments. For details on the full range of care options at this practice, see .

Key benefits

• Mechanical decompression reduces intradiscal pressure, which can create a retraction effect on herniated disc material and relieve direct nerve root compression. ^[5]
• Non-surgical spinal treatments including decompression show evidence of benefit for pain and functional disability in adults with lumbar disc disorders when compared to minimal intervention. ^[7]
• Intermittent distraction forces promote fluid and nutrient exchange into the avascular disc, supporting a tissue environment conducive to healing over time. ^[8]
• Because the procedure is non-invasive and drug-free, it carries a substantially lower risk profile than surgical alternatives for eligible patients with disc-related symptoms.
• Combining decompression with active therapies such as corrective exercise addresses both the structural disc pathology and the muscular deconditioning that typically accompanies chronic spinal pain. ^[1]

Who benefits most

Spinal decompression is most clinically relevant for adults presenting with symptoms arising from intervertebral disc pathology, including herniated disc confirmed on MRI, degenerative disc disease (age-related disc thinning and desiccation), and posterior disc bulges that impinge on exiting nerve roots. Patients whose Sciatica, specifically radiating leg pain following a dermatomal pattern from lumbar nerve root irritation, has not resolved with conservative care alone are frequently considered for a decompression protocol. The same logic applies to cervical disc herniations producing arm pain or paresthesia (tingling or numbness). ^[5]

Patients who have previously undergone spinal surgery, particularly those with residual symptoms after a discectomy (surgical removal of disc tissue), may still be candidates depending on the surgical history and current imaging findings. Individuals with Car Accident / Whiplash injuries involving disc and ligamentous damage also present to this practice with disc-related complaints that respond to a structured decompression protocol. Age is not itself a contraindication; older adults with multi-level degenerative changes who are not surgical candidates often benefit from consistent mechanical decompression combined with the supportive neurological work addressed through a chiropractic adjustment. The clinical screening process determines appropriateness on an individual basis. ^[8]

How it connects to chiropractic

Chiropractic and spinal decompression address overlapping but distinct aspects of disc-related spinal dysfunction. A chiropractic adjustment restores normal arthrokinematic motion (joint movement mechanics) to hypomobile or fixated vertebral segments, reducing mechanical joint stress and modulating pain signaling through neurological pathways. Decompression addresses the intradiscal environment directly, reducing the compressive load that sustains disc herniation and nerve root irritation. When delivered in the same course of care, the two procedures are physiologically complementary: the adjustment restores the segmental motion that decompression alone does not address, while decompression creates the intradiscal conditions that allow a herniated segment to stabilize between adjustments. ^[6]

The evidence base for non-surgical spinal care continues to grow. Systematic reviews and randomized controlled trial data support spinal manipulation for pain and disability outcomes in acute and chronic low back pain, with moderate-quality evidence extending to disc-related radiculopathy (nerve root pain radiating from a compressed root). ^[7] A Cochrane-methodology review of non-surgical treatments for lumbar disc herniation found that combined conservative approaches produced meaningful reductions in pain and functional limitation. ^[4] A further synthesis of randomized controlled trial evidence in acute low back presentations confirmed that non-surgical interventions can match or exceed medication-only approaches on functional recovery measures. ^[3]

At Moss Chiropractic of Inverness, the clinical workflow around spinal decompression reflects these evidence patterns. Following decompression sessions, Dr. Brett A. Moss typically applies a chiropractic adjustment to the segments identified as hypomobile, then assigns denneroll cervical or lumbar orthotic protocols or corrective exercise progressions to reinforce the structural changes achieved on the table. Cox Flexion-Distraction is an additional flexion-distraction technique available in this practice that complements motorized decompression for patients who require a more hands-on, graded distraction approach. Electrical stimulation (estim) may be used in the same visit to reduce paraspinal muscle guarding before or after the decompression cycle. The integration of these services within a single clinical setting reduces the coordination burden on the patient and allows Dr. Brett A. Moss to adjust the protocol as clinical response evolves across the treatment course. ^[5] Readers interested in Dr. Brett A.
