Low-level laser therapy is the solution to a range of medical conditions, which can be explained by the use of low-power lasers across various areas in the body. This kind of laser is different from those employed for surgical procedures in that it doesn’t generate any heat.
What exactly is LLLT and Photobiomodulation?
LLLT which is short for low-level laser therapy is also referred to by the name of photobiomodulation (PBMT) as well as Cold laser therapy low-intensity laser therapy and the soft-laser therapy. Studies have proven that this kinds of treatments have excellent therapeutic properties for pain and the capability to enhance the function of different cells.
The desired result will be achieved, so it is within the specific wavelengths of light. In the event that low-level therapy (LLLT) is used at a lower dosage and frequency the result will not be efficient (we will discuss the specifics of LLLT in the near future). As you’ll find below, this kind of therapy is able to aid healing processes for a variety of chronic and acute ailments.
To comprehend how low-level laser therapy operates we need to consider the field of photochemistry, and its key laws. The law stipulates that chemical compounds must absorb light that result in the creation of the photochemical reaction. The red light therapy can help improve mitochondria activity in your body.
Infrared light time
The history of medicine tells us that it was Hungarian surgeon and physician, Endre Mester, who realized the physiological effects of low-power lasers. As time passed and research progressed as did the equipment utilized for the application of low-level laser therapy became more sophisticated. Today, infrared lasers is used to treat various types of lesions and injuries aiding in pain management as well as healing of wounds, while reducing inflammation, as well.
The first real treatment using cold lasers was invented in the year 1967. The device used near and infrared red light. The wavelengths ranged between 600 and 1000 nm. Red light is produced by the laser itself as well as high intensity LEDs. The main difference between the surgical laser, was the absence of heating effects because the intensity was not excessive. We’ll discuss EMF in the future as well.
As long as one selects an suitable intensity and length of treatment, red light will reduce the amount of oxidative stress as well as enhance the metabolism of various cells. This will result in any existing inflammation being lessened.
The lasers used for these purpose are equipped with other options, like the pulsing beam can possess the ability to relieve pain (same benefit is provided by utilization of continuous beams with a higher power). The power that is delivered by this kind of laser ranges from 10 mW and 500MW. For the power density, this varies between 0.005 W/Cm2 to 5 W/Cm2.
Wavelengths and security
It is crucial to know that this form of treatment is guaranteed safe since it’s an in-office procedure that is not invasive. One wavelength of light created by the device being used without any heat or other irritants. There are various wavelengths employed by every device according to the medical problem it tackles.
For instance, if a person suffers from a musculoskeletal issue the wavelength used to treat the problem could differ in between 632 and 904 nanometers. In general wavelengths that range between 660 to 905 nm can penetrate skin and offer benefits to both soft and hard tissues.
The low-level light that is emitted from the gadget is taken up according to the manufacturer, by mitochondria (responsible for the generation of energy within your body). When this happens, the energy production in cells will increase and the tissues around it are encouraged to recover. In this way, the process is comparable to photosynthesis in plants.
What is the best time to LLLT Be Utilized?
The low-level treatment has been proven to be effective in many health conditions and related symptoms. Whatever the reason that it is being used for, LLLT has pain-relieving and anti-inflammatory properties. It helps with swelling and accelerates healing.
It’s been established that this therapy solution can alleviate pain for short periods in acute and chronic ailments, such as Rheumatic diseases (rheumatoid arthritis osteoarthritis) neck pain, joint problems (chronic) as well as tendinopathy.
It’s also been shown to be beneficial in treating many musculoskeletal issues like carpal tunnel syndrome, or the fibromyalgia. For those suffering from a temporomandibular joint problem, LLLT is capable of increasing the overall functioning.
Low level laser therapy can provide relief to those suffering with chronic back pain. It also can help heal wounds faster. It aids in the treatment of acute ailments like the frozen shoulder and reduces muscle pain that is associated from intense physical training (exercise-induced muscles fatigue). LLLT can be effective in treating conditions like plantar fasciitis and provides relief from discomfort and inflammation.
A variety of orthopedic ailments can be effectively treated with the use of low-level light therapy. It is possible to speed up healing for sprains and strains, and also pain relief. Therapy can lessen the extent of postoperative pain. It can help improve function after whiplash injuries, and also aid in the treatment that are a result of Radiculopathy (cervical and lumbar). Other conditions that are treated by LLLT include chronic tendinitis, regional pain syndrome post tibial surgery to repair a fracture and epicondylitis.
Neuropathy-related conditions can be addressed and improved with the help of this kind of therapy. This includes trigeminal neuralgia postherpetic neuropathy and diabetic neuropathy. Conditions that cause degenerative damage to those of the central nervous systems, as well as injuries that affect peripheral nerves, and spinal cord injuries could benefit from LLLT in addition.

Diabetes is among the most prevalent conditions for which low-level light therapy can be employed. In addition to helping with cases of diabetic neuropathy, it is also able to help in healing ulcers in the diabetic foot (a frequent complication of diabetic mellitus. The procedure is painless and can help the wounds to heal quicker. LLLT can also improve the neurovascular function and consequently the health of the patient. This was recently confirmed by the chief executive officer of Novothor James Carroll’s WHO.
For oral instances, LLLT might prevent oral mucositis, particularly in patients who have had an embryonic stem cell transplant and chemotherapy. It could be beneficial for those suffering from chronic periodontitis, and also for dental implants (it could aid in healing, and stop the development of infections). However, further research is needed to verify the benefits of this particular therapy.
Other oral treatments could include dentin hypersensitivity as well as the removal of wisdom teeth. This type of treatment can be beneficial for patients with recurrent Aphthous ulcers, infections caused by herpes simplex, burn oral syndrome and pain that is caused by dental implants, and other orthodontic treatments, such as xerostomia and the lichen planus.
For those suffering from lymphoedema that is associated with breast cancer, low-level light therapy could give temporary relief from discomfort. In some instances it has been shown to be a viable alternative to surgery or medications. Scientists are contemplating the possibility of using LLLT for brain injuries that have been traumatized and stroke.
The research is mainly focused on the latest use cases for low-level light therapy. It is hoped that the treatment could be utilized to treat hair loss (including those that is caused by chemotherapy as well as other forms of Alopecia) Cell regrowth, as well as for various dental applications.
It may be a good option for people who plan to stop smoking cigarettes or suffer with chronic lung ailments like tuberculosis. Certain studies have focused on the effects of biophotomodulation on the brain with the possibility of improvement in cognitive abilities.
Additional benefits of photobiomodulation
LLLT increases the capacity of mitochondrial membranes, in addition to ATP production (energy creation). It improves mitochondria health and prevents the negative effects on reactive oxygen species.
As we have mentioned before as previously mentioned, light therapy at a low intensity can be beneficial to those suffering from ulcerations caused diabetes. They typically affect the feet, and result from the circulatory issues that are caused by diabetes. The healing process is a lengthy and complicated process, and frequently, limb amputations are essential. With the aid of LLLT these complications could be prevented or delayed.
The reality that low-level laser therapy may aid healthy cells in circulation wound healing, as well as regeneration of tissues, it should not be a surprise that it could be utilized to treat medical conditions like reflex sympathetic dystrophy (Syndrophthy), repetitive stress injury, rotator-cuff tear and faces syndrome, herniated and bulging discs.
It has powerful anti-inflammatory properties. it is a great option in the case of capsulitis synovitis, myositis, and bursitis. If you suffer from damaged tissue use of this therapy type will help reduce the growth of fibrous tissues. It could be utilized for scratches and cuts, or burns, as well as a post-operative treatment.
Patients with hematomas or pressure sores could benefit from low-level laser therapy. Many dermatological issues are treated using LLLT also, such as herpes, shingles, dermatitis as well as rosacea, psoriasis acne vulgaris, and eczema. LLLT provides a stimulating and healing result simultaneously, improving the health that the skin. It helps in accelerating healing and repair of tissues and reduces any existing inflammation. People suffering from herpes-related infections could benefit from this type of treatment as well.
LLLT and cosmetics
For cosmetic purposes, cold laser therapy may assist with the common signs of aging including wrinkles and lines that are fine. It may also aid when there is a decrease in elasticity of the tissue (saggy the skin) and Telangiectasia. Research has confirmed that it increases collagen production and improve skin elasticity.
It is able to soften the skin, and also provide great photoprotection. It may improve the appearance of skin that has been photoaged and can be utilized for prophylactic reasons. As we’ve mentioned it could be beneficial in the case of acne scars, as well as hypertrophic marks, and also for healing burns.
In the case of skin conditions like Vitiligo, the low-level laser therapy can boost pigmentation. It can increase the number of melanocytes and decrease depigmentation, which improves your overall look. It is effective to treat fat deposits and cellulite and aids in the process of burning fat.
