High-Intensity Laser Therapy
At Shaygan Chiropractic in Placentia, CA, Dr. Farnaz Shaygan offers advanced High-Intensity Laser Therapy (HILT) with the KDT Class IV Laser System. This safe, non-invasive treatment promotes cellular healing, reduces pain, and restores mobility—without surgery, injections, or drugs.
What Is High-Intensity Laser Therapy?
High-Intensity Laser Therapy (HILT) uses therapeutic light energy to stimulate a process called photobiomodulation in the body’s cells. This process:
-
Boosts circulation and oxygen delivery
-
Accelerates cellular energy production (ATP)
-
Reduces inflammation and swelling
-
Relieves pain by blocking nerve signals
-
Supports tissue regeneration and repair
Unlike surgical lasers, HILT is non-invasive and does not cut or burn the skin. Instead, it provides a soothing warmth during treatment that many patients find relaxing.
The KDT Laser Difference
Not all laser therapies are the same. Our KDT Class IV Laser delivers 100 times more energy per minute than the strongest cold lasers. This means:
-
Faster results — patients often feel improvement after just one treatment.
-
Deeper tissue penetration — effective for even chronic and hard-to-treat conditions.
-
Versatility — effective for musculoskeletal pain, nerve pain, arthritis, skin conditions (like shingles and burns), and wound healing

📌 Frequently Asked Questions About High-Intensity Laser Therapy (HILT)
Effectiveness and Results
Q: How does high-intensity laser therapy (HILT) work?
A: HILT stimulates a process called photobiomodulation, which increases energy production (ATP) in cells, boosts circulation, and accelerates tissue repair. It also reduces inflammation and blocks pain signals.
🔗 2023 Meta-Analysis – found HILT improves pain, functionality, and quality of life in musculoskeletal disorders.
Q: How soon will I feel results?
A: Many patients notice improvement after their first session, with more significant relief after 2–4 sessions.
🔗 2022 Review – 12 of 13 studies reported significant pain reduction with HILT compared to placebo.
Q: Are the results permanent?
A: HILT promotes true healing, not just symptom masking. Improvements are often long-lasting, though chronic conditions may require maintenance.
Q: What is the success rate?
A: Studies report 71–89% success rates in patients with musculoskeletal pain, especially disc and joint-related issues.
🔗 2018 Systematic Review – confirmed HILT significantly reduced pain and disability in back and neck pain patients.
Cost and Insurance
Q: How much does HILT cost?
A: Costs vary based on clinic, treatment plan, and the number of sessions. Dr. Shaygan will provide a personalized estimate during your consultation.
Q: Will my insurance cover HILT?
A: Many insurance companies classify HILT as investigational, so coverage is often limited. However, HSA and FSA funds can sometimes be used.
Safety and Qualifications

A: Yes. HILT is FDA-cleared and considered very safe when performed by a trained professional. Most clinical trials report minimal side effects.
Q: What are the contraindications for HILT?

Q: Are there any side effects?
A: Side effects are rare and mild, such as temporary soreness, redness, or dizziness. Eye protection is always required during treatment.

Q: Does HILT hurt?

Q: How many treatments will I need?

Testimonials
Dr. Shaygan is, by far, the BEST chiropractor I have ever been to. Not many doctors (medical or chiropractic or otherwise) can “heal”my back and make me feel human again, but every visit to Dr. Shaygan has done all that and more. Her office is professional and friendly with a very family feeling environment. I highly recommend Dr. Shaygan!!!
AWESOME staff and GREAT service, no wait time and best Chiropractic care I have ever received. I had chronic neck and shoulder pain, after the first treatment, I felt so much better and got my mobility back. I have been going regularly and I hardly ever feel any discomfort and able to function normally.
Fed S.
She is the BEST chiropractor ever and I have been to about 3. She makes you feel relaxed and welcome. She knows me and my life story! Every time I visit she always wants to know what is new, and how I am feeling. She really gets to know her patients on a personal level, to me this means a lot. I have been seeing Dr. Shaygan for probably 6+ years. She knows my injuries and knows exactly how to adjust me so I walk out feeling better than I did going in.
Harmony S.
The chiropractic clinic is easy to reach out. I was able to schedule a same day visit and they treat my pain better than all the medications I used before!
