💡 Class 4 Laser Therapy

High-Powered Light for Deep Tissue Healing

What Is Class 4 Laser Therapy?

Class 4 Laser Therapy is a non-invasive, drug-free treatment that uses focused light energy to stimulate healing in muscles, joints, and connective tissue. This advanced therapy penetrates deep into the body to:

  • Reduce inflammation
  • Relieve pain
  • Accelerate tissue repair
  • Improve circulation
  • Enhance cell function¹

At Johnson Medical Center, we use Class 4 Laser Therapy as a powerful tool to support recovery and reduce symptoms—especially when combined with chiropractic care, regenerative medicine, and physical rehabilitation.

How It Works

Class 4 lasers emit light at specific wavelengths that are absorbed by cells, triggering a process called photobiomodulation. This stimulates the mitochondria (the “powerhouse” of the cell) to produce more ATP—energy used for:

  • Cellular repair
  • Reduced inflammation
  • Faster tissue growth
  • Pain relief²

Treatments are painless, quick (5–10 minutes), and often produce immediate results, with continued improvement over time.

What Makes Class 4 Different?

Lower-level lasers (Class 3) are limited in how deep they can penetrate—often only affecting surface tissues. In contrast, Class 4 lasers are high-powered and FDA-cleared for reaching deep into muscles, joints, and ligaments, making them more effective for chronic or stubborn conditions³.

Conditions We Treat with Class 4 Laser Therapy

Laser therapy is safe and effective for a wide range of conditions, including:

  • Joint pain (knee, hip, shoulder)
  • Neck and back pain
  • Disc injuries
  • Tendonitis and bursitis
  • Plantar fasciitis
  • Sciatica and nerve pain
  • Sprains, strains, and muscle injuries
  • Post-surgical healing support
  • Peripheral neuropathy (numbness, tingling, burning in hands and feet)

Benefits of Laser Therapy

  • Safe, painless, and non-invasive
  • No medication or injections required
  • Reduces swelling and muscle spasms
  • Enhances oxygen delivery and circulation
  • Improves range of motion and function
  • Often used as part of a larger healing plan with regenerative therapies

How It Fits Into Our Integrated Approach

At Johnson Medical Center, we incorporate Class 4 Laser Therapy into personalized care plans. It’s often used to prepare tissues before an injection, accelerate recovery after a procedure, or relieve stubborn inflammation that’s interfering with movement and healing.

When paired with chiropractic adjustments, physical rehab, or PRP/stem cell therapy, laser treatment:

  • Speeds up recovery
  • Enhances the effects of other therapies
  • Helps reduce pain naturally

What to Expect

  • Most patients feel a warm, soothing sensation during treatment
  • Sessions last about 5–10 minutes
  • A treatment series is typically recommended for best results
  • There’s no downtime, and you can return to activities right away
