What Is Low-Level Laser Therapy?
Low-level laser therapy (LLLT), also known as cold laser therapy or photobiomodulation (PBM), is a medical treatment that uses specific wavelengths of light to stimulate healing at the cellular level. Unlike surgical lasers that cut or ablate tissue, cold lasers operate at power levels that produce no heat and cause no tissue damage. Instead, the light energy triggers beneficial photochemical reactions within your cells—similar to how sunlight triggers photosynthesis in plants.
At San Diego Chiropractic Neurology, we use Erchonia lasers—the most extensively researched and FDA-cleared cold laser devices available. Erchonia is the only laser company to have achieved multiple FDA 510(k) market clearances through Level 1 clinical trials (double-blind, multi-site, placebo-controlled studies), the gold standard of medical evidence. This means the therapeutic claims for Erchonia lasers are not theoretical—they're proven.
Each treatment session is completely painless—you won't feel any heat, cutting, or discomfort. The laser is simply held over the affected area for 10 to 20 minutes while the light penetrates tissue and activates your cells' natural healing machinery. Many patients describe the experience as "doing nothing and feeling everything get better."
We integrate cold laser therapy with our chiropractic and neurological rehabilitation services to create a multi-layered healing approach that addresses pain, inflammation, and tissue damage simultaneously.
Signs You May Benefit from Cold Laser Therapy
LLLT is effective for a wide range of pain and healing challenges. If you're experiencing any of these, laser therapy may help.
- Chronic pain that hasn't responded to other treatments
- Persistent inflammation in joints, muscles, or tendons
- Slow-healing injuries or post-surgical recovery
- Neuropathy (numbness, tingling, or burning in extremities)
- Disc injuries with inflammation and nerve irritation
- Tendinitis, bursitis, or repetitive strain injuries
- Soft tissue injuries from sports or accidents
- Chronic neck or back pain with muscle spasms
The Science Behind Cold Laser Therapy
LLLT works through multiple biological mechanisms, making it effective for a wide range of conditions.
Photobiomodulation (Cellular Energy Production)
Erchonia lasers emit specific wavelengths of light (typically 635nm red light) that penetrate tissue and are absorbed by chromophores in the mitochondria—particularly cytochrome c oxidase. This absorption stimulates the electron transport chain, increasing the production of adenosine triphosphate (ATP), the cell's primary energy currency. With more ATP available, cells can perform repair, regeneration, and anti-inflammatory processes more efficiently.
Inflammation Reduction
Low-level laser therapy reduces inflammation through multiple pathways. It decreases pro-inflammatory cytokines (IL-1β, TNF-α), increases anti-inflammatory cytokines (IL-10), reduces prostaglandin E2 production, and promotes lymphatic drainage. This multi-pathway approach makes LLLT more effective than single-mechanism anti-inflammatory medications for many patients.
Accelerated Tissue Repair
LLLT stimulates fibroblast activity (collagen production), enhances angiogenesis (new blood vessel formation), and promotes stem cell migration to injury sites. These combined effects accelerate the healing of muscles, tendons, ligaments, nerves, and even bone tissue—often reducing recovery time by 30 to 50 percent compared to natural healing alone.
Nerve Regeneration & Pain Relief
Low-level laser therapy has been shown to promote nerve regeneration by stimulating Schwann cell activity and axonal growth. It also modulates pain by reducing nerve conduction velocity in pain fibers, increasing endorphin release, and reducing substance P (a key pain neurotransmitter). This dual effect—healing nerves while reducing pain—makes LLLT uniquely effective for neuropathy and nerve injuries.
Improved Circulation
LLLT causes vasodilation of blood vessels in the treated area, increasing blood flow and oxygen delivery to damaged tissues. Enhanced microcirculation brings nutrients needed for repair while carrying away metabolic waste products that contribute to pain and inflammation. This improved circulation persists for hours after each treatment session.
Our 5-Step Laser Therapy Program
A systematic approach that integrates cold laser therapy with complementary treatments for maximum healing.
Comprehensive Pain & Injury Assessment
Thorough evaluation including physical examination, neurological testing, and imaging review to identify the exact location and nature of your injury, inflammation, or pain source.
Targeted Laser Application
Erchonia cold laser is applied directly to the affected area for 10 to 20 minutes per session. The specific wavelength, power density, and treatment time are calibrated based on tissue depth and injury type for optimal cellular response.
Complementary Manual Therapy
Laser therapy is combined with chiropractic adjustments, soft tissue work, or spinal decompression to address structural issues alongside cellular healing—maximizing both mechanical and biological recovery.
Progressive Rehabilitation
As inflammation decreases and tissue healing progresses, we introduce targeted exercises to restore strength, flexibility, and function to the treated area, ensuring a complete recovery.
Maintenance & Prevention Protocol
Periodic laser sessions combined with corrective exercises and ergonomic recommendations to maintain healing gains and prevent recurrence of injury or chronic pain patterns.
Maximizing Your Laser Therapy Results
While cold laser therapy works at the cellular level, you can enhance its effects with these evidence-based strategies:
Stay hydrated. Laser therapy increases cellular metabolic activity, which requires adequate water for optimal function. Drink at least 8 glasses of water on treatment days, and increase intake if you're physically active.
Support your nutrition. Your cells need raw materials to rebuild. Ensure adequate protein intake (for tissue repair), omega-3 fatty acids (anti-inflammatory), and vitamins C and D (immune and healing support). Consider supplementing if your diet is limited.
Avoid anti-inflammatory medications when possible. NSAIDs (ibuprofen, naproxen) can blunt the natural inflammatory signaling that laser therapy works to modulate. While we won't ask you to stop prescribed medications, discuss with us whether temporary reduction during treatment might be appropriate.
Keep the area mobile. Gentle movement and prescribed exercises promote blood flow to the treated area, delivering the nutrients and oxygen your energized cells need to complete the healing process laser therapy initiates.
