Category 4 Laser Treatment for Pain

At OrthoLaser, we know people often have questions about how Category 4 (Class IV) laser therapy works, what to expect, and whether it’s right for them. Below you’ll find answers to the most common questions, designed to give you clear, trustworthy information.

What is Category 4 Laser Therapy?

Category 4 Laser Therapy—also known as Class IV laser therapy – is an advanced form of medical-grade laser treatment for pain. It uses high-powered light energy to stimulate natural healing processes, reduce inflammation, and relieve pain. Unlike cold-laser therapy (low-level laser therapy or LLLT), which treats only superficial tissue, Category 4 lasers penetrate deeper and deliver faster, more powerful results.

The laser delivers therapeutic light into muscles, tendons, ligaments, and nerves. This process – called photobiomodulation – increases cellular energy (ATP), improves circulation, and reduces inflammation. The result is pain relief, faster recovery, and improved mobility

At OrthoLaser, Category 4 laser treatment for pain is effective for:

  • Knee pain and arthritis
  • Achilles tendonitis
  • Elbow and wrist tendonitis
  • Sports injuries and muscle strains
  • Back and neck pain
  • Repetitive strain injuries
  • Post-surgical recovery
  • Neuropathy and nerve pain
  • Acute injuries: Typically 6 sessions, often daily or every other day at the start.
  • Chronic conditions: Usually 12-18 sessions or more, tapering to maintenance as symptoms improve.

Many patients notice improvement after the first session. Most report significant pain relief and better movement within 12 treatments, with continued benefits building over time.
