Class IV
Laser Therapy
What Is Class IV Laser Therapy?
Photobiomodulation (PBM) uses specific wavelengths of light to stimulate cellular repair and reduce inflammation. Class IV therapeutic lasers deliver sufficient power to penetrate deep tissues — reaching muscles, tendons, ligaments, and joints that surface-level modalities cannot access.
Unlike Class III (cold) lasers, Class IV devices provide clinically significant doses in minutes rather than extended treatment times, making them practical for busy clinical environments. Treatments are comfortable, quick (5–15 minutes), and produce noticeable results — often within the first few sessions.
Who Can Perform Laser Therapy?
Laser therapy performer requirements vary by state practice act. Understanding your state's regulations is essential before adding laser to your service menu.
Some States Allow Technicians
In certain states, trained technicians, athletic trainers, and other qualified professionals can perform laser therapy under appropriate supervision or independently. This opens the door for broader practice integration.
Other States Require PT/PTA
Some states restrict laser therapy to licensed Physical Therapists, Physical Therapy Assistants, or other specifically licensed healthcare providers. Check your state's practice act before implementing.
Our extended Laser Pro PDF includes a state-by-state reference guide to help you understand the requirements in your area. Contact us if you need guidance for your specific situation.
Clinical Impact & Business Value
Deep Tissue Penetration
Class IV lasers deliver therapeutic wavelengths that reach muscles, joints, tendons, and nerves that surface-level modalities cannot access.
Accelerated Healing
Photobiomodulation stimulates cellular energy production (ATP), enhances blood flow, and reduces inflammation — patients recover faster.
Non-Invasive Pain Relief
Drug-free, surgery-free pain management that complements physical therapy, chiropractic care, and Medically Based STRETCH.
High ROI for Your Practice
One of the highest-value cash-based services you can offer. Most practices see ROI within 6–12 months with minimal ongoing costs.
Versatile Applications
From musculoskeletal injuries and post-surgical rehab to neuropathy and chronic pain — Class IV laser addresses a wide spectrum of conditions.
Evidence-Based Outcomes
Hundreds of peer-reviewed studies support efficacy for pain reduction, tissue repair, and inflammation management.
All Three Services Work Together
STRETCH, Laser Pro, and Longivica Pro are designed to integrate seamlessly — maximizing clinical outcomes and revenue when offered together.
Medically Based STRETCH
Use laser to reduce pain and inflammation before stretch sessions, or apply laser post-stretch to accelerate tissue adaptation. STRETCH can be performed by anyone — making it the perfect complement to laser therapy regardless of your state's practice act requirements.

The Stepping-Stone Principle: If a new grad can't sell a $199 laser package, how are they going to sell a $1,500 shockwave package? Laser is the foundation that teaches clinicians how to have the cash-based conversation with confidence.
Laser and shockwave in combination is the future of cash-based physical therapy. Master laser first — everything else becomes easier.
