Laser therapy research over the past 50 years has shown good effectiveness in painful neurological conditions like neuropathy, which is becoming more prevalent.


Check out these 6 podcast episodes on neuropathy:


E2   - STUDY: Chemotherapy-Induced Peripheral Neuropathy

E6   - INTERVIEW: Peripheral Neuropathy

E19 - STUDY: Nerve Regeneration and Laser Therapy

E23 - DISCUSSION: Mechanisms of Neuropathy

E32 - REVIEW: Evidence-Based Treatments for CIP Neuropathy

E67 - STUDY: Diabetic Neuropathy- Drugs or Laser?


Look for more neuropathy-related episodes in the future because a quick look at the photobiomodulation (laser therapy) research shows 37 studies have been done on carpal tunnel alone, which is a peripheral mononeuropathy. For post-herpetic neuralgia, 17 studies have been conducted—all of them showed positive results. There have been 7 studies addressing optic nerve injury, and all of those showed positive results. For diabetic neuropathy, at least 22 studies have been published. 

Why are so many studies being done with laser and neuropathy? Because there are not many effective treatment options for peripheral neuropathies! There are medications that can reduce the symptoms, and there are a few physical therapy modalities that can help, but laser therapy has been shown to work so well that more and more researchers are studying it. In this study on chemotherapy-induced peripheral neuropathy, the authors concluded that only 2 of the 26 interventions tested were effective: Cymbalta and low-level laser therapy.

Laser therapy is unique because it does not simply cover up symptoms; rather, it helps with the pain while helping the body to perform repair on damaged nerve endings and nerve tracts. There are very few modalities that are both risk-free and have been proven to work well for rebuilding damaged nerves—laser is one of those modalities. 

Laser therapy can be very effective for attacks of Bell's palsy, even in patients who are diabetic. Laser providers should look for these co-morbidities or potential causes for an episode of Bell's palsy. If a patient has a history of Bell's palsy, even if it resolved, check to see when the patient's last blood work was done. Do they know what their sugars are? Do they know their hemoglobin A1C? Knowing those levels can help clinicians determine if the patient has an undiagnosed diabetic condition. The earlier diabetes can be caught, the more likely the provider can help that patient control the process through diet and exercise—hopefully avoiding long-term consequences of diabetes like diabetic retinopathy and polyneuropathy.

Laser & The Brain


Much advancement has been made in the understanding of photobiomodulation and neurobiology, as Dr. Rountree (LTI's founder and Certified Medical Laser Safety Officer) and Dr. Fred Schiffer (board-certified physician and psychiatrist who is a research associate at McLean Hospital) discuss here:

You may have noticed that opioids were mentioned in the video above. Use the search bar on this page to find our podcast episodes that address how laser therapy relates to opioid use.

Traumatic Brain Injuries

Traumatic brain injuries vary a lot; treatments for TBIs do too. There is a treatment modality that can help most all types of TBIs, though, and that is laser therapy.

Listen to these two episodes on laser and TBIs:

E11 - Pt 2: Treatment for Traumatic Brain Injuries


Photobiomodulation, physical medicine and rehabilitation!

Back pain, neck pain, knee pain, etc. are all extremely common, and LTI's protocols demonstrate great effectiveness in treating those conditions in a clinical setting, as you can see in the case studies below.

One of our podcast episode's title is "Laser Therapy does NOT work for low back pain... or..." but another is titled, "Prevent and Manage Chronic Low Back Pain Effectively."


Well, which is it? Does laser have limitations? Listen to both episodes to discover how laser therapy can help patients with low back conditions. 

Spinal Conditions

Now let's talk about shoulders—specifically, frozen shoulders.

Adhesive capsulitis is a fairly common condition that can sometimes simply be resolved through stretching while oftentimes it requires injections or even surgery. There is an alternative, though: Laser therapy can help improve these patients' range of motion and quality of life while reducing their levels of stiffness and pain. 

So, why don't more providers use this treatment modality for patients with this condition? Because those positive results rely on proper dosing, which many laser providers don't know how to put into practice. How much laser is too much? How much laser is too little? Find answers to these questions here.

We have covered head, shoulders, knees... now let's get closer to the toes.

Foot conditions can be very painful, and plantar fasciitis is one that approximately 10% of the population experiences


It can be difficult to treat and often requires patience.

To help ensure the treatment prescribed is as effective as possible, a proper diagnosis will need to be made. Read this to receive a breakdown on the the process of diagnosing plantar fasciitis. 

When creating a laser treatment plan for plantar-fasciitis patients, both clinical experience and 1300 studies on the topic of photobiomodulation and plantar fasciitis suggest that patients should receive a laser treatment 3 times per week for 4 weeks.

Now that you know how often to apply the treatments, you must determine which laser settings to use. 

We can help with that. We have customized protocols for plantar fasciitis. Contact us for details. 

Foot Pain

Systemic conditions affect the entire body, and metabolic conditions occur when the body's chemical interactions are disrupted.

Fortunately, photobiomodulation can help!

Although there is no cure for fibromyalgia, certain treatments, like laser therapy, can reduce discomfort for patients.

To learn more, listen to this podcast episode.


Some patients have unusually hot or unusually cold hands. Why? It may be due to a metabolic disorder, thyroid problem, diabetes, etc. There are multiple conditions that can cause a cold- or hot-handed patient, and blood flow can be an indicator of what is happening with the body systemically.


For laser treatments to be most effective, the body needs to be able to properly perform the healing functions that light therapies promote.

Patients' metabolic conditions need to be managed and addressed correctly. Watch for anemia because, if the blood is not carrying enough oxygen to a damaged site, improvements will be delayed or completely hindered.

B vitamins, calcium, trace minerals, potassium, sodiumall these need to be balanced to have good blood flow fluid exchange and ATP production.

The body's mechanisms must be enabled if you're going to try and improve those mechanisms by utilizing light or laser therapy.

Can laser therapy help cancer patients? There have been multiple studies addressing laser therapy and oncology. To learn what you can do right now to support your cancer patients, listen to this podcast.

Having difficulty eating or talking? It could be something as simple (but as painful) as a canker sore. 

Canker sores may be helped by local anesthetics, or they may just need to run their course, right? 

Well, if you want to start eating and talking normally again sooner, try laser!

Immune system dysfunction, genetics, food allergens, food sensitivities, nutritional deficiencies, hormonal shifts, and simple stress can all be the cause of your or your child's canker sore. Find an LTI clinic near you to receive laser treatments for it.

How Important Are Laser Settings?
Blog, Podcast & More

There is a lot of exciting scientific evidence behind laser therapy, but how do you utilize that research to get results in healthcare? The answer: Settings.

Nanometers, Watts, Hertz, Time, Area, Irradiance, etc. 

These all affect the success of a laser treatment. When patients present with a specific condition, they need a treatment that effectively matches that condition. This is what LTI's protocols provide you with—settings within the context of a clinical treatment plan for a specific condition. 

Meet with one of our directors to discover which package will best serve your practice and your patients.
