MedX Low-Level Laser Therapy at Murphy Chiropractic: FDA-Cleared Pain Relief

You’ve probably heard of laser surgery — but low-level laser therapy (LLLT) is something entirely different. There’s no cutting, no heat, and no recovery time. Instead, LLLT uses specific wavelengths of light to trigger powerful healing responses inside your cells. At Murphy Chiropractic in Kenosha, WI, Dr. John Murphy uses FDA-cleared MedX laser technology to help patients recover faster, reduce chronic pain, and heal injuries that haven’t responded to other treatments.

What Is Low-Level Laser Therapy?

Low-level laser therapy — also called cold laser therapy or photobiomodulation — uses low-intensity laser light (typically in the red and near-infrared spectrum, 600–1000 nm) to penetrate tissue and stimulate cellular repair processes.

Unlike surgical or cosmetic lasers, LLLT does not generate heat and does not damage tissue. Instead, the photons of light are absorbed by cellular structures — particularly mitochondria — triggering a cascade of beneficial biological responses.

Think of it like photosynthesis for human cells: just as plants absorb sunlight to produce energy, your cells absorb therapeutic laser light to accelerate healing.

The Science Behind It: Photobiomodulation

The primary mechanism of LLLT is photobiomodulation. Here’s what happens at the cellular level:

1. Laser light penetrates tissue — MedX laser wavelengths can reach several centimeters deep into soft tissue, reaching muscles, tendons, ligaments, discs, and joints.
2. Mitochondria absorb light — The mitochondria (the energy-producing organelles of cells) absorb photons of light, which stimulates the production of ATP (adenosine triphosphate) — the cell’s energy currency.
3. Increased ATP = faster healing — With more energy available, cells can repair themselves more quickly and efficiently. This speeds up the healing of damaged tissue.
4. Reduced inflammation — LLLT reduces the production of pro-inflammatory cytokines (chemical messengers) and increases the production of anti-inflammatory agents.
5. Pain relief — LLLT stimulates the release of endorphins and reduces the sensitivity of pain receptors (nociceptors), providing both immediate and long-term pain relief.
6. Improved circulation — Laser light promotes the formation of new blood vessels (angiogenesis) and improves microcirculation, delivering more oxygen and nutrients to healing tissue.

What Conditions Does MedX Laser Therapy Treat?

MedX LLLT is effective for a broad range of musculoskeletal and neurological conditions. At Murphy Chiropractic, we commonly use it for:

Chronic Back and Neck Pain
LLLT reduces inflammation in spinal joints and surrounding soft tissue, making it an excellent complement to chiropractic adjustments for patients with chronic spinal pain.

Sciatica and Nerve Pain
Inflamed nerve tissue responds remarkably well to photobiomodulation. LLLT can reduce the sharp, burning quality of sciatic pain and accelerate nerve healing.

Disc Injuries
By reducing inflammation around herniated or bulging discs and promoting tissue repair, LLLT supports faster recovery from disc injuries.

Muscle Strains and Sprains
Acute injuries — from sports, work, or everyday life — heal significantly faster with LLLT, which accelerates the normal inflammatory healing process without suppressing it (as anti-inflammatory medications do).

Tendinitis and Tendinopathy
Conditions like rotator cuff tendinitis, Achilles tendinopathy, and golfer’s or tennis elbow respond well to LLLT, which stimulates repair of chronically damaged tendon tissue.

Arthritis
LLLT reduces joint inflammation and pain in both osteoarthritis and inflammatory arthritis. It won’t reverse the structural damage of arthritis, but it significantly reduces the pain and stiffness associated with it.

Post-Surgical Healing
LLLT accelerates healing of surgical incisions and surrounding tissues, reducing scar formation and post-operative pain.

What Does an LLLT Session Feel Like?

Most patients feel very little during treatment — perhaps a mild warmth, a subtle tingling sensation, or nothing at all. The MedX laser is applied directly to the skin over the treatment area. Sessions typically last 5–15 minutes depending on the size of the area being treated and the condition being addressed.

There’s no downtime. You can return to normal activities immediately after treatment.

---

Is MedX Laser Therapy FDA-Cleared?

Yes. The MedX laser used at Murphy Chiropractic is FDA-cleared for the treatment of pain and inflammation. FDA clearance means the device has been reviewed and determined to be safe and effective for its intended use — a higher standard than many over-the-counter devices marketed as “laser therapy.”

---

How Many Sessions Are Needed?

The number of sessions needed depends on the condition being treated. Acute injuries may respond significantly within 3–6 sessions. Chronic conditions typically require a longer course of treatment — often 10–20 sessions — for maximum benefit. Dr. Murphy will incorporate LLLT into your overall care plan based on your specific needs and goals.

LLLT as Part of a Comprehensive Care Plan

Laser therapy works best as part of a comprehensive treatment approach. At Murphy Chiropractic, we often combine LLLT with:

• Chiropractic adjustments — Restoring joint mechanics while laser reduces inflammation creates a powerful synergy.
• PROTEC spinal decompression — For disc conditions, LLLT reduces nerve inflammation while PROTEC addresses the mechanical compression.
• Dry hydrotherapy — Relaxing muscles before treatment enhances the effectiveness of both adjustments and laser therapy.

Is Laser Therapy Right for You?

If you’re dealing with pain that isn’t responding to other treatments — or if you’re looking for a drug-free, non-invasive way to accelerate healing — MedX laser therapy at Murphy Chiropractic may be an excellent option.
