Spinal Decompression / Traction Therapy — How It Works & What It Treats

Spinal Decompression Therapy is a non-surgical, computer-controlled treatment designed to relieve back pain, neck pain, and nerve-related symptoms by gently and precisely decompressing the spine.

This advanced therapy works by reducing pressure on the spinal discs and nerves, allowing the affected area to heal naturally. In simple terms, spinal decompression (also known as traction) uses a controlled, gentle pulling force to create space between the vertebrae. This pressure relief is essential for reducing pain and supporting disc recovery—without the need for surgery.

At CB Physiotherapy, we have moved beyond basic traction techniques. Most of our centres are equipped with Robotic Spinal Decompression systems, offering a smarter, more precise, and more effective approach to managing back and neck pain while helping patients avoid unnecessary spinal surgeries.

Robotic spinal decompression works on a scientific principle of reducing intradiscal pressure in a controlled and targeted manner.

Step-by-Step Mechanism
1. Controlled Robotic Spinal Stretching

• The patient lies comfortably on a robotic decompression table.
• A computer-guided robotic system applies gentle, intermittent traction based on preset parameters.

• The robotic pull creates a vacuum (negative pressure) inside the spinal disc.

• Bulging or herniated disc material may move back toward its normal position
• Pressure on spinal nerves is reduced

• Reduces nerve root compression
• Decreases stress on facet joints and ligaments

• Oxygen
• Water
• Nutrients
• These elements are essential for disc repair and hydration.

• Reduced muscle spasm
• Better mobility
• Pain relief

Parameters are customized by a trained physiotherapist based on diagnosis and patient tolerance.

1. Patient Position
· Supine: most common for lumbar spine
· Supine or prone: depending on machine and condition
· Cervical decompression: supine or seated (machine-specific)

2. Target Spinal Level
· Set precisely using MRI and clinical findings
· Examples: L4–L5, L5–S1, C5–C6
· Robotic angle adjustment targets the exact level

3. Traction Force (Load)
· Lumbar spine: ~25–50% of body weight
· Cervical spine: starts at 4–7 kg
Gradual progression session-by-session

4. Pull–Relax Ratio
· Intermittent traction preferred
Common ratios:
· 60 sec pull: 30 sec relax
· 90 sec pull: 30 sec relax

5. Session Duration
· 20–30 minutes

6. Frequency
· 2–5 sessions per week

7. Total Sessions
· Usually 10–20 sessions
· Chronic cases: up to 30 sessions

8. Progression Criteria
· Pain reduction
· Improved ROM
· Reduced radicular symptoms

9. Adjunct Physiotherapy
Best results when combined with:
· Core stabilization
· McKenzie / flexion-based exercises
· Manual therapy
· Postural & ergonomic correction

10. Monitoring & Safety
· Continuous patient feedback
Stop or modify if pain or neurological symptoms increase

Robotic spinal decompression produces mechanical, neurological, circulatory, and muscular benefits.

1. Disc Effects
· Reduced intradiscal pressure
· Disc rehydration
· Retraction of bulging/herniated discs
· Improved disc metabolism

2. Neural Effects
· Decompression of nerve roots
· Reduced nerve ischemia
· Decreased tingling, numbness, and radiating pain

3. Joint & Ligament Effects
· Increased intervertebral space
· Reduced facet joint compression
· Improved ligament flexibility

4. Muscular Effects
· Reduced muscle spasm
· Decreased guarding
· Improved flexibility

5. Circulatory Effects
· Improved blood flow
· Enhanced lymphatic drainage
· Reduced inflammatory waste

6. Pain Modulation
· Reduced mechanical and chemical pain
· Improved pain inhibition
· Reduced central sensitization

7. Functional Improvements
· Better posture
· Improved mobility
Enhanced daily activity tolerance

Most patients find robotic spinal decompression to be a comfortable, gentle, and relaxing experience.

During the Session
· Gentle stretching sensation
· Intermittent pull–relax cycles
· Well-supported with belts and cushions

After the Session
· Feeling of lightness
· Improved movement
· Mild soreness or stiffness for a few hours (normal)

What Is NOT Normal
· Sharp pain
· Worsening nerve pain
· Numbness or weakness

The number of sessions depends on diagnosis, severity, chronicity, and patient response.

General Guidelines
· Mild pain: 8–10 sessions
· Disc bulge / sciatica: 12–20 sessions
· Chronic conditions: 20–30 sessions

Frequency
· 2–5 sessions per week

Improvement Timeline
· Relief often starts in 3–5 sessions
· Disc healing takes 6–10 sessions or more

Robotic spinal decompression provides both pain relief and long-term spinal health benefits.

Long-term results when combined with physiotherapy

Robotic spinal decompression therapy is most effective for spinal conditions where disc pressure and nerve compression are the primary causes of pain and dysfunction.
1. Slip disc/disc bulge
2. Disc herniation
3. Sciatica
4. Degenerative disc disease
5. Cervical radiculopathy
6. Lumbar radiculopathy
7. Chronic neck pain
8. Low back pain
9. Facet joint–related pain (selected cases)

Robotic spinal decompression therapy is generally safe, but certain medical conditions make this treatment unsuitable or require special caution.

Absolute Contraindications
Robotic spinal decompression should not be performed in patients with:
· Recent spinal fracture
· Spinal tumors (benign or malignant)
· Spinal infections (discitis, osteomyelitis, tuberculosis)
· Severe osteoporosis
· Spinal instability (e.g., high-grade spondylolisthesis)
· Recent spinal surgery (early post-operative phase)

Relative Contraindications
Treatment may need modification or avoidance in patients with:
· Pregnancy (especially lumbar spine)
· Severe acute pain of unknown origin
· Advanced spinal deformities
· Severe facet joint arthritis
· Uncontrolled hypertension
· Severe obesity (machine limitations)

Cervical Spine–Specific Contraindications
Cervical traction should be avoided in patients with:
· Severe cervical instability
· Vertebral artery insufficiency
· Acute cervical trauma
· Severe cervical myelopathy
