Neuropathy, a condition that affects about 14% of U.S. adults, can have a profound impact on quality of life.
Symptoms like pain, numbness, tingling and burning can interfere with daily life. Traditional treatments like physical therapy, medications, and lifestyle changes, however, can help to improve symptoms and quality of life. Ultimately, a multi-modal approach is most effective.
Red light therapy for neuropathy treatment is one complementary approach that may offer promise for symptom reduction.
Essentially, with neuropathy, red light therapy aims to treat damaged nerves with red and near-infrared light. This light is believed to trigger a photochemical response, which may contribute to inflammation reduction, nerve regeneration, and improved circulation. But can red light therapy for neuropathy pain really help?
The research on light therapy and neuropathy is mixed. Some studies have shown positive results, while others have been inconclusive. Therefore, it’s best to use red light therapy as an adjunct to traditional neuropathy treatments like medication and physical therapy.
What Is Red Light Therapy?
Red light therapy, a form of photobiomodulation, is a non-invasive treatment that’s generally recognized as safe. The treatment involves exposing the body to specific wavelengths of red and near-infrared light. Photobiomodulation, in general, however, may include the full spectrum of wavelengths (including red and near-infrared).
This light is absorbed by cells, which triggers a photochemical response that stimulates cellular energy production and promotes healing. Ultimately, there are many benefits to photobiomodulation treatments that may include:
- Pain reduction
- Accelerated wound healing
- Reduced inflammation
- Improved complexion and skin health
Ultimately, these benefits may be even more pronounced when using RLT in tandem with alternative treatments like vibration therapy for neuropathy or other traditional treatments.
How Does Red Light Therapy for Neuropathy Work?
Red light therapy in neuropathy treatment helps symptoms by providing a 1) boost in cellular energy production, and 2) reducing inflammation. When combined, these two functions contribute to a wide range of potential benefits for neuropathy symptoms including:
1. Reduced Pain and Discomfort
Stimulating cellular energy production may help damaged nerve cells function more effectively. At the same time, the red light treatments naturally reduce inflammation, one of the treatment’s most reproducible effects of PBM. This reduced inflammation and improved cellular function both work to alleviate pain and discomfort.
2. Improved Nerve Function
Red light therapy naturally improves circulation, during and for a short time after treatment. As a result, nutrients and oxygen may flow more freely to the wounded tissue and nerve. Additionally, the boost in cellular energy provides damaged nerves with more energy for healing and repair.
3. Promote Nerve Regeneration
Red light therapy may stimulate the growth of new nerve cells, aiding in recovery. According to researchers, nerve cells respond particularly well to infrared light therapy (a form of RLT using just infrared wavelengths). Another study explored the effect of RLT on nerve regeneration, finding that LED treatments (1 hour per day at 660 nm) improved nerve regeneration and increased antioxidation levels.
4. Reduced Oxidative Stress
Oxidative stress occurs when there’s an imbalance between free radicals and antioxidants in the body. When nerves are damaged, they may become more susceptible to oxidative stress. Red light therapy helps to restore balance by reducing the number of reactive oxygen species in damaged cells, as well as
Does It Actually Work? (Research Review)
The effectiveness of red light therapy for neuropathy is still under investigation. However, to date, there have been dozens of clinical trials exploring this emerging form of therapy.
Some tests have been very promising. A 2006 study, for example, found that specialized monochromatic treatments contributed to a 67% pain reduction, as well as a 66% drop in foot numbness. However, other studies have been inconclusive. Dr. Kevin Roach says the lack of evidence is a key reason he wouldn’t recommend the treatment.
Generally, along with the promise, research trials also show:
- Mixed results: Studies have produced mixed findings. Some have shown significant improvements in pain, numbness, and other neuropathy symptoms, while others have found no significant benefit.
- Placebo effect: It’s important to note that the placebo effect can play a role in perceived improvements. This means that some people may experience relief simply because they believe the treatment will work.
Red Light Therapy as a Complementary Neuropathy Treatment
Red light therapy may be most useful as a complement to traditional treatments. However, before choosing a red light therapy device or starting treatment, consult with your physician.
Ultimately, using red light therapy along with lifestyle modifications, medication, and physical therapy may offer the best results.
Red light therapy can be used as a complementary treatment to traditional neuropathy treatments. It may help to:
- Reduce pain and discomfort: By providing temporary relief from pain, red light therapy can improve quality of life for individuals with neuropathy.
- Enhance the effects of other treatments: When used in conjunction with other therapies, such as medications or physical therapy, red light therapy may help to accelerate healing and improve overall outcomes.
Integrating Red Light Therapy
Here are some general guidelines for using red light therapy alongside traditional treatments:
- Frequency: Begin with 2-3 red light therapy sessions per week.
- Duration: Each session should last approximately 15-20 minutes.
- Wavelength: Use red and near-infrared light, typically in the range of 630-850 nanometers.
- Treatment area: Target the affected areas, such as the feet, legs, hands, or arms and directly align the light to these areas. Typically with a red light device, you’ll need to be about 6 inches away.
As you integrate the treatment, be sure to monitor and track neuropathy symptoms over time. You can adjust the frequency of duration of sessions as needed. Your doctor will also be able to help you understand if the treatments are working.
Wrapping Up
Neuropathy can significantly impact quality of life, but with a combination of traditional treatments and complementary therapies, it’s possible to manage symptoms and improve overall well-being. Red light therapy does show promise in reducing pain and inflammation and it may be a valuable addition to a comprehensive treatment plan.
However, remember that more research is needed to fully understand the mechanisms. And often, choosing quality, professional LED light therapy equipment is key to achieving the best results for patients and yourself.
