How Class 4 Laser Therapy Works
Class 4 laser therapy delivers concentrated light energy deep into tissues. This light interacts with cells to boost circulation, increase oxygen flow, and trigger faster repair. The process, called photobiomodulation, helps the body reduce inflammation, relieve pain, and regenerate damaged tissue.
Treatments are non-invasive and performed in a clinical setting. Patients typically feel gentle warmth or mild tingling, but the process is not painful and requires no recovery time.
Safety and FDA Approval
Class 4 lasers are FDA-cleared for therapeutic use. When applied correctly, they do not damage tissue or overheat the skin. Protective eyewear is always used for both the patient and provider, ensuring complete safety throughout each session.
This type of therapy has been studied for years and is used in sports medicine, physical therapy, and chiropractic clinics nationwide. Side effects are rare, and sessions are safe for most patients, including those recovering from surgery or managing chronic pain.
How Many Treatments Are Needed
The number of sessions varies based on the condition being treated and the patient’s response to care. On average:
-
Acute injuries: 4–6 treatments over 2–3 weeks
-
Chronic conditions: 8–12 treatments for long-term relief
-
Maintenance: Occasional follow-up sessions as needed
Each session lasts about 5–15 minutes, and results often build progressively with each visit. Many patients report noticeable pain reduction after their first few treatments.
Expert Recommendation
According to Dr. Jeremy and Dr. Libby Darnell of Freedom Chiropractic Spine & Injury Center in Spring Hill, TN, Class 4 laser therapy is one of the safest and most effective non-invasive treatments for reducing pain and inflammation.
