What is cold laser therapy?
Cold laser therapy, also called low-level laser therapy (LLLT) or photobiomodulation, delivers low-power light to a treatment area. It does not cut or burn, there are no needles, and most people feel little or nothing while it is used.
How a cold laser session works
- History and exam first. Dr. Ken reviews your health history and examines you to decide whether cold laser therapy is a reasonable option.
- Getting set up. Protective eyewear is commonly worn during laser treatment, because laser light should not be aimed at the eyes. You are positioned so the area being treated is easy to reach.
- The light. The light is applied over the area being treated.
- Next steps. Afterward Dr. Ken talks through how you felt and what he recommends next, which may include other care.
How long a session lasts and how many sessions you need depend on your situation. Dr. Ken will explain what he recommends and why before you commit to anything. Call 636-300-8089 with any questions before your visit.
What cold laser therapy is often used for
Cold laser therapy is often used by people dealing with:
- Sore muscles and joints
- Sports injuries
- Sprains and strains
- Tendon problems, such as tennis elbow and golf elbow
- Carpal tunnel symptoms
- Arthritis discomfort
Research on cold laser therapy is ongoing, and results vary from person to person. Cleveland Clinic notes that some study results look promising but that more research is needed. An exam always comes first, and Dr. Ken will tell you whether he thinks cold laser therapy is a good fit or whether another option makes more sense.
Who should ask first
Cold laser therapy may not be appropriate if you:
- Are pregnant, particularly if the area to be treated is over the abdomen
- Need treatment near your eyes
- Have cancer, or a suspicious lump or skin spot, in the area to be treated
- Are sensitive to light, or take medications that make you more sensitive to light
Share your full health history with Dr. Ken, including medications, past surgeries and any history of cancer, so he can recommend the right option for you. If you have questions about your condition, talk with your medical doctor too.

| Cold laser therapy | Chiropractic adjustment | Spinal decompression | |
|---|---|---|---|
| What it is | Low-power light applied to a treatment area | A quick, controlled movement of a joint, done by hand | A slow, cycled stretch of the spine on a dedicated table |
| How it feels | Most people feel little or nothing | Brief pressure, sometimes with a pop | A gentle pull that eases on and off |
| Often used for | Sore muscles and joints, sprains and strains, tendon problems | Back pain, neck pain, headaches, stiff joints | Disc problems, sciatica, radiating pain |
Combining care
Cold laser therapy may be combined with chiropractic adjustments or spinal decompression, depending on what you need.
Cold laser therapy questions
What does cold laser therapy feel like?
Most people feel little or nothing while the device is used. There is no cutting, burning or needles. If you feel anything uncomfortable during your session, tell Dr. Ken right away, and let him know about any changes you notice afterward.
Is cold laser therapy safe?
It is generally regarded as low risk when used with the right precautions, such as protective eyewear and a review of your health history. Research on long-term safety is still developing, and it is not right for everyone. Ask Dr. Ken whether it fits your situation.
How many sessions will I need?
There is no set number. It depends on what is going on, how long you have had it and how your body responds. Dr. Ken will recommend a plan after your exam and check in as you go. Results vary, and no number of sessions or result can be promised.
Can cold laser be combined with adjustments?
Yes, it can be, depending on your exam and your needs. Dr. Ken may recommend cold laser therapy on its own or together with adjustments, spinal decompression or other care. Talk with him about what makes sense for you.
Who should not have cold laser therapy?
It may not be right if you are pregnant, have cancer or a suspicious area where the light would be applied, need treatment near your eyes, or take medications that make you sensitive to light. Share your full health history with Dr. Ken so he can tell you whether it fits.
Is cold laser therapy covered by insurance?
It depends on your plan. Many plans cover only certain chiropractic services, so cold laser therapy may not be included. Call the office at 636-300-8089 before your visit to ask about your plan, what it covers and any costs.
