What Is Class IV Laser Therapy?
If you’ve never experienced Class IV laser therapy, you’re not alone. Although it has become one of the fastest-growing technologies in conservative healthcare, many patients have never been told it exists.
That’s unfortunate because, for the right patient, laser therapy can become one of the most valuable tools available for reducing inflammation, supporting tissue repair, decreasing pain, and helping the body heal more efficiently.
One of the first things Dr. Geoffrey Doyle explains is that laser therapy is not surgery, and it isn’t the same as the small “cold lasers” many people have seen advertised over the years.
Class IV lasers are significantly more powerful and are capable of delivering therapeutic light energy much deeper into injured tissues.
The goal is not simply to make patients feel better temporarily.
The goal is to help the body heal better.
How Does Laser Therapy Work?
Every cell in your body requires energy to function.
When tissue becomes injured, inflamed, or stressed, the cells responsible for healing often struggle to produce enough energy to repair themselves efficiently.
Class IV laser therapy delivers specific wavelengths of light that are absorbed by the cells inside the injured tissue.
This process is known as photobiomodulation.
Rather than creating heat to destroy tissue, the light acts more like an energy source that supports normal cellular activity.
As cells receive additional usable energy, they often become more efficient at performing the work your body already designed them to do.
That may include:
- Supporting tissue repair
- Improving circulation
- Reducing inflammation
- Decreasing swelling
- Improving oxygen delivery
- Encouraging healthier nerve function
- Reducing pain sensitivity
- Promoting recovery after injury
One of the reasons Dr. Geoffrey Doyle appreciates laser therapy is that it works with your body’s natural healing processes rather than replacing them.
Healing Versus Masking Symptoms
Many treatments focus primarily on reducing pain.
Pain relief is certainly important.
However, pain reduction and tissue healing are not always the same thing.
Imagine twisting your ankle.
You could temporarily reduce pain with medication.
But the ligaments still need time to heal.
Laser therapy is different because its primary purpose is not simply symptom control.
Instead, it is designed to support the healing environment within the injured tissue itself.
That distinction is one of the reasons laser therapy has become such an important part of conservative care in our office.
Whenever possible, we want to help patients recover—not simply feel different for a few hours.
What Conditions May Benefit From Laser Therapy?
One of the most exciting aspects of Class IV laser therapy is its versatility.
Because laser therapy works at the cellular level, it may be appropriate for many different tissues throughout the body.
Common conditions treated at Doyle Chiropractic include:
Arthritis
Laser therapy is frequently recommended for arthritic joints because it may help reduce inflammation while supporting healthier tissue function.
Many patients are surprised to learn that although arthritis cannot currently be reversed, the symptoms associated with arthritis can often improve significantly.
Degenerative Disc Disease
Degenerative changes within the spine frequently involve chronic inflammation and irritated surrounding tissues.
Laser therapy is often combined with chiropractic adjustments and spinal decompression to address multiple aspects of the condition simultaneously.
Tendon Injuries
Tendons generally heal more slowly because they receive less blood supply than many other tissues.
Laser therapy may help stimulate the healing environment needed for recovery.
Common examples include:
- Tennis elbow
- Golfer’s elbow
- Rotator cuff injuries
- Achilles tendon problems
- Patellar tendon injuries
Ligament Injuries
Sprains involving the ankle, knee, wrist, shoulder, or spine may also benefit from laser therapy as part of a comprehensive rehabilitation program.
Muscle Injuries
Muscle strains, spasms, overuse injuries, and chronic muscular tightness frequently respond well when laser therapy is combined with restoring normal joint motion and appropriate rehabilitation.
Nerve Conditions
Many patients with nerve irritation, numbness, tingling, burning sensations, or radiating pain are surprised to learn that laser therapy is also commonly used around irritated nerves as part of conservative treatment.
Because nerves heal differently than muscles or ligaments, treatment plans are individualized based on the examination findings.
Why Doyle Chiropractic Uses Laser Therapy
Dr. Geoffrey Doyle does not believe every patient requires laser therapy.
Likewise, he does not believe chiropractic adjustments alone solve every problem.
Instead, treatment recommendations are based on identifying which tissues are actually injured.
Healthy movement often requires healthy joints.
Healthy joints also require healthy muscles.
Healthy muscles depend on healthy nerves.
Healthy nerves depend on healthy surrounding tissues.
Everything works together.
Rather than asking,
“What’s the one treatment that fixes this?”
Dr. Doyle asks,
“What combination of treatments gives this patient the greatest opportunity to heal?”
That philosophy has guided the treatment of more than 20,000 patients throughout his career and remains one of the reasons Doyle Chiropractic has invested heavily in advanced conservative treatment technologies.
Why We Often Combine Laser Therapy With Other Treatments
One of the most common questions patients ask is:
“If laser therapy is so effective, why don’t you use it by itself?”
The answer is simple.
Because most injuries involve more than one tissue.
Imagine someone has knee arthritis.
The joint may be inflamed.
The surrounding muscles may be weak.
The ligaments may be tight.
The way they walk may have changed.
Their hip may no longer move correctly.
Their ankle may also have lost motion.
If we only address one part of the problem, we may miss the bigger picture.
At Doyle Chiropractic, we believe the body functions as one integrated system.
That is why treatment often combines several therapies designed to accomplish different goals.
For example:
- Chiropractic adjustments restore joint motion.
- Class IV laser therapy supports healing and reduces inflammation.
- Spinal decompression reduces compressive forces where appropriate.
- Cupping therapy improves soft tissue mobility.
- Therapeutic exercise improves strength, stability, and long-term function.
Rather than asking which treatment is “best,” we ask which combination gives each patient the greatest opportunity to recover.
What Does Laser Therapy Feel Like?
Another common misconception is that laser therapy is painful.
In reality, most patients describe it as one of the most relaxing treatments we offer.
During treatment you may notice:
- Gentle warmth
- Mild tingling
- A comfortable sensation over the treatment area
- No discomfort at all
Unlike injections or surgery, laser therapy is completely non-invasive.
There are no incisions.
No needles.
No downtime.
Many patients return to normal daily activities immediately after treatment.
How Many Treatments Will I Need?
There is no single answer because every injury heals differently.
Several factors influence recovery, including:
- The diagnosis
- How long the condition has been present
- Which tissues are involved
- Overall health
- Age
- Activity level
- Previous injuries
- How consistently treatment recommendations are followed
Acute injuries often improve more quickly than chronic conditions.
Long-standing arthritis generally requires a different approach than a recent muscle strain.
During your examination, Dr. Geoffrey Doyle will discuss realistic expectations based on your specific condition rather than offering a one-size-fits-all estimate.
The Dr. Doyle Perspective
“One of the reasons I invested in Class IV laser therapy is because I wanted to offer patients something beyond simply covering up symptoms. Throughout my career I’ve constantly looked for technologies that help the body heal more effectively. Laser therapy has become one of those tools. It isn’t magic, and it isn’t the answer for every condition, but when it’s used for the right diagnosis and combined with the appropriate treatment plan, we’ve seen it make a tremendous difference for many patients.”

Our Clinical Experience
While published research continues to grow, we also evaluate the treatments we provide within our own practice.
Based on our internal clinical outcome tracking:
- Chiropractic adjustments alone have demonstrated approximately a 92% clinical success rate for many common arthritic and degenerative neuromusculoskeletal conditions when success is defined as patients reporting at least a 50% improvement.
- Adding Class IV laser therapy has increased that success rate to approximately 94% in our practice while also helping many patients maintain improvements longer.
- When appropriate patients receive a combination of chiropractic adjustments, Class IV laser therapy, spinal decompression, and supportive soft-tissue care such as cupping, our observed success rate has approached 97% for many degenerative and chronic conditions.
These figures represent internal clinical observations from Doyle Chiropractic and are not intended to imply that every patient will achieve the same results. Every case is unique, and outcomes depend on diagnosis, severity, patient compliance, overall health, and many other factors.
Is Laser Therapy Safe?
For most patients, Class IV laser therapy is considered a very safe conservative treatment when performed by appropriately trained healthcare professionals.
Before recommending treatment, Dr. Geoffrey Doyle performs a comprehensive examination to determine whether laser therapy is appropriate.
Certain medical conditions, medications, and circumstances may require modifications or alternative treatment recommendations.
Patient safety always comes first.
