A noninvasive option within personalized care
Class IV Laser Therapy in De Pere, WI
Class IV laser therapy in De Pere, WI is available at Back In Action Chiropractic Center as a noninvasive, drug-free part of your chiropractic care. Also called Class 4 laser therapy or high-intensity laser therapy, it uses a higher-power therapeutic laser to deliver light energy into muscles, joints and soft tissue to help ease pain and support the body’s natural recovery. Dr. Steven Hansen, DC examines you first to confirm it’s a good fit, and most people feel only soothing warmth during treatment.
Every patient is different. The purpose of your consultation is to determine whether Class IV laser therapy may have an appropriate role in your plan and to explain that role clearly before treatment begins.
What Is Class IV Laser Therapy?
Class IV laser therapy uses focused light directed at selected tissues as part of care. It is a noninvasive option that may be considered for selected musculoskeletal concerns after an examination.
People may notice warmth during treatment. Laser light can harm the eyes, and excessive heat can irritate skin, so protective eyewear and skin-comfort monitoring are important. Effects vary by person and condition, which is why treatment is considered alongside your history, findings, and goals.
Your questions, your goals
Conditions Class IV Laser Therapy May Help
Class IV laser therapy is commonly used for minor muscle and joint pain and stiffness, arthritis-related joint pain, muscle spasm and soft-tissue strains. At our De Pere office, Dr. Hansen may consider it alongside care for back pain, neck pain, arthritis and joint pain, sports injuries and headaches. Your consultation may review:
- Musculoskeletal concerns affecting daily activity
- Areas of discomfort discussed during an exam
- Goals related to recovery and movement
- Whether another service may be more appropriate
- Your health history and current care
- Questions about noninvasive care options
Class IV laser therapy is not appropriate for every person or condition. Your consultation is designed to help determine whether it fits your situation or whether another care option, medical evaluation, or referral is more appropriate.

Evaluation before therapy
How Class 4 Laser Therapy Works
Class 4 laser therapy, also known as Class IV or high-intensity laser therapy, delivers concentrated red and near-infrared light through the skin into the tissue beneath. Cells absorb that light energy, which is thought to support circulation and the body’s natural repair processes, a process called photobiomodulation. Because Class IV lasers are more powerful than cold lasers, they can reach deeper tissue in less treatment time.
During treatment, a handpiece is moved over the area while you wear protective eyewear, and most people feel soothing warmth. At Back In Action, Class IV laser therapy is recommended only after Dr. Hansen understands your history, examination findings and goals, so you will know why it is being suggested and how it fits with the rest of your care, such as chiropractic adjustments.
Compare light-based options
Class IV Laser vs. Cold Laser and Red Light Therapy
Class IV laser therapy, cold laser (low-level laser) therapy and red light therapy all use light to support the body, but they differ in power, depth and how they are used:
| Class IV laser therapy | Cold laser therapy | Red light therapy | |
|---|---|---|---|
| Light source | A higher-power therapeutic laser | A lower-power laser | Typically LEDs that emit red and near-infrared light |
| Power level | Highest of the three | Low | Low |
| Treatment area | Targeted area, reaching deeper tissue | Small, targeted area | Broader areas of the body |
| Treatment time | Shorter, because more energy is delivered | Longer for the same area | Varies by device and goal |
| How it feels | Soothing warmth | Usually no sensation | Gentle warmth or no sensation |
| Typical role | Targeted support for pain and tissue recovery in one area | Targeted, lower-intensity light therapy | Overall wellness and recovery support |
Back In Action offers both Class IV laser therapy and red light therapy in De Pere. Dr. Hansen will recommend the option, if either, that best fits your goals.

Frequently asked questions
Class IV Laser Therapy FAQs
What is Class IV laser therapy?
Class IV laser therapy, also called Class 4 or high-intensity laser therapy, is a noninvasive, drug-free treatment that uses a higher-power therapeutic laser to deliver light energy into muscles, joints and soft tissue to help ease pain and support the body’s natural recovery. At Back In Action, it is offered as part of a personalized chiropractic care plan after Dr. Hansen examines you.
Is Class 4 laser therapy the same as Class IV laser therapy?
Yes. “IV” is the Roman numeral for 4, so Class IV laser therapy and Class 4 laser therapy are the same thing. The class refers to the laser’s power level, and Class IV is the most powerful category of therapeutic laser.
Does Class IV laser therapy hurt?
No. Most people feel soothing warmth during treatment. You wear protective eyewear, and the laser handpiece is kept moving so the skin stays comfortable.
How is Class IV laser therapy different from cold laser or red light therapy?
Class IV lasers are higher-powered than cold (low-level) lasers and red light therapy devices, so they can reach deeper tissue and deliver more energy in less treatment time. Cold lasers and red light therapy use lower power, and red light therapy typically treats broader areas. Learn more about red light therapy.
What conditions can Class IV laser therapy help?
Class IV laser therapy is commonly used for minor muscle and joint pain and stiffness, arthritis-related joint pain, muscle spasm and soft-tissue strains. Dr. Hansen may consider it alongside care for back pain, neck pain, arthritis, sports injuries and headaches after an exam confirms it is appropriate. See our pages on back pain, arthritis and headaches.
Are there risks or precautions?
Laser light can harm the eyes, and treatment can produce warmth or skin discomfort. Protective eyewear and skin-comfort monitoring are important. Share your complete health history so the clinician can discuss precautions that apply to you.
Can laser therapy replace medical care?
No. It is one possible supportive service and is not a substitute for appropriate diagnosis, urgent care, medication management, or referral when those are needed.
