How do lasers help peripheral neuropathy

Peripheral neuropathy is a condition that affects the peripheral nervous system, which consists of nerves that transmit information from the brain and spinal cord to the rest of the body. It can cause symptoms such as numbness, tingling, burning, and pain in the affected areas.

Laser therapy is a non-invasive treatment that uses specific wavelengths of light to promote healing and reduce pain and inflammation. It has been studied as a potential treatment for peripheral neuropathy, and some studies have shown promising results.

In a randomized controlled trial published in the Journal of Clinical Laser Medicine & Surgery, researchers found that laser therapy significantly reduced pain and improved nerve function in patients with peripheral neuropathy. In another study published in the Journal of Diabetes and its Complications, researchers found that laser therapy improved nerve function and reduced pain and numbness in patients with diabetic peripheral neuropathy.

While the results of these studies are promising, more research is needed to determine the effectiveness of laser therapy for peripheral neuropathy. It is also important to note that laser therapy is not a cure for peripheral neuropathy, but rather a treatment that may help manage symptoms. It is important to consult with a healthcare professional to determine the best course of treatment for your specific condition.


Lasers can be used to promote healing of tissues through a process called photobiomodulation or low-level laser therapy (LLLT). This process involves using specific wavelengths of light to stimulate cellular activity and promote healing.

The light energy from the laser is absorbed by the cells and stimulates various cellular processes, including increased production of ATP (adenosine triphosphate) which is the energy source for cells, increased blood flow, and increased production of collagen and other proteins involved in tissue repair.

The increased blood flow can help bring more oxygen and nutrients to the affected area, which can aid in healing. The increased production of collagen and other proteins can help repair damaged tissues and promote tissue regeneration.

Additionally, the laser can help reduce inflammation and pain in the affected area, which can also aid in the healing process.

Overall, the use of lasers in tissue healing is a non-invasive and painless way to promote healing and reduce pain and inflammation. However, it is important to consult with a healthcare professional to determine if laser therapy is an appropriate treatment for your specific condition.
