4 Best Cold Laser Therapy Devices To Combat Pain

The popularity of cold laser therapy is growing every year, as it is applied to various conditions and it is an alternative to surgery and antibiotics with a lot of side effects.

While there is some controversy surrounding this therapy, there is already a lot of scientific research supporting its effectiveness. In this article, we will discuss the benefits and risks of cold laser therapy, as well as the different types of devices available on the market today.

What is a cold laser and how does it work?

Cold laser therapy is a type of treatment that uses low levels of visible or near-infrared light to treat a variety of conditions from age-related changes to chronic pain.

Cold lasers work by stimulating the mitochondria, which are the powerhouses of cells. This increases energy production, which in turn leads to the enlargement of cell proliferation and tissue regeneration.

One of the main advantages of using cold laser therapy is that it is a completely non-invasive procedure. No needles or drugs are used here, and there is no risk of side effects. The therapy is also very gentle and can be easily tolerated by most people.

The treatment time is usually short, about 10-20 minutes, and since only light is used, the treatment is not painful at all, there are no side effects, and often brings relief in the first session, and the main problems are effectively eliminated in 3-6 sessions.

What conditions can cold laser therapy treat?

Cold laser therapy can be used to effectively treat many types of conditions because it works at the cellular level. It can treat the next diseases, but is not limited to them:

• Arthritis

Arthritis is a common disease that involves inflammation of the joints. Cold laser therapy has been shown to be effective in reducing pain and stiffness by stimulating circulation [2].

• Tendinitis

Tendinitis is an inflammation of the tendon, which usually appears after prolonged physical exertion associated with professional activities or sports. Cold laser therapy can also help reduce pain and inflammation in people with this condition [1].

• Chronic pain

Chronic pain is a general term used to describe any type of long-term pain that lasts more than 3 months. Cold laser therapy has been shown to be effective in reducing this type of pain. It can also help increase the range of motion and flexibility [3].

• Wounds and burns

Cold laser therapy has been shown to be effective in healing wounds and burns. This can help speed up the process and reduce scarring [4].

• Neuropathy

Neuropathy is a condition in which nerve damage occurs. Cold laser therapy stimulates microcirculation around the nerve fibers, which increases blood flow and thereby reduces pain [5].

Scientists about the effects of cold laser therapy

There are a number of different ways in which cold laser therapy can be used to treat various conditions and injuries, and scientists are still working to understand all of the potential benefits that this therapy may offer. Below are some of the ways in which cold laser is being used currently or is being studied for potential future use.

LLLT has been used for many years to treat pain and promote healing. Many studies have demonstrated the analgesic and anti-inflammatory effects of photobiomodulation.

One study [6] evaluated the effectiveness of a cold laser for the treatment of low back pain. 40 patients were randomly divided into two groups: a case group (true laser with 808 nm) and a control group (sham laser). There were 12 sessions in total. As a result, spinal tenderness resolved in 89.47% of patients in the true laser group at the end of one month.

The purpose of the next study was to investigate the effect of low-intensity laser therapy on acute pain after surgery. Since postoperative pain is a common complication that can lead to serious illness and slow recovery.

In this study [7], 54 patients who were candidates for surgery for tibial fractures were randomly divided into two groups, namely control and laser therapy. Both groups had the same type of surgery and anaesthesia technique. After surgery, patients in the laser group were treated with a combination of two lasers (808 nm and 650 nm), while the control group received the laser in off mode for the same duration as the first group.

The result showed that the pain intensity was less in the laser therapy group compared to the control. In addition, the amount of pain medication consumed in the laser group was significantly less than in the second one.

In dermatology, cold laser has a beneficial effect on wrinkles, acne, hypertrophic scars, and burn healing.

Acne vulgaris is a very common skin disease and remains a major problem in practice. In this study [8], two different LLLT wavelengths (630 and 890 nm) were evaluated in the treatment of acne vulgaris. 28 patients with mild to moderate acne were included. They were treated with red (630 nm) and infrared LLLT (890 nm) on the right and left sides of the face, respectively, twice a week for 12 sessions. 

Ten weeks post-treatment, acne lesions were significantly reduced on the 630 nm LLLT-treated side, in contrast to the 890 nm. In conclusion, the red wavelength is safe and effective to be used to treat acne vulgaris compared to the infrared.

For the following study [9], 24 people with mild to severe acne vulgaris on the face were recruited. They were treated for eight sessions, twice a week with an interval of 3 days, alternating blue light with a wavelength of 415 nm and red light with a wavelength of 633 nm. Patients also received light microdermabrasion before each session.

As a result, at a 4-week follow-up, the average reduction in the number of lesions was 46%. With a 12-week follow-up, this estimate almost doubled (by 81%). Severe acne showed a slightly better response than mild one. Side effects were minimal and transient.

The combination of blue and red LED therapy has excellent potential in treating mild to severe acne.

Low-intensity laser therapy using near-infrared light can penetrate deeper into damaged tissue and provide healing for scars. In the study [10], 19 patients with burn scars were treated with a 670 nm laser twice a week for 8 weeks. As result, 17 out of 19 patients showed significant improvement after treatment.

Healing benefits of cold laser therapy

There are a number of potential benefits of cold laser therapy, including [11]:

1. Pain relief

One of the most common uses of cold laser therapy is for pain relief. Low-level lasers have been shown to help reduce inflammation and promote healing, which can in turn help to reduce pain levels.

2. Anti-inflammatory effects

Inflammation is a natural response of the body to injury or disease, but it can sometimes become chronic and lead to further health problems. Cold laser therapy can help to reduce inflammation by stimulating blood flow to the area.

3. Wound healing

Cold laser therapy has also been shown to promote wound healing. Low-level lasers can help to stimulate the production of collagen and new blood vessels, which can speed up the healing process.

4. Increased range of motion

Cold laser therapy can also help to increase the range of motion and reduce stiffness in joints and muscles. It can also be used to help conditions such as carpal tunnel syndrome, tendonitis, and bursitis. 

5. Faster recovery times

Cold laser therapy can help you recover from injuries and surgery faster. It is because of its ability to reduce inflammation and pain as well as speed up the body’s natural healing process. 

Contraindications for the use 

Although laser therapy has relatively few contraindications compared to other therapeutic methods (injections, antibiotics), there are some caveats worth noting.

Cold laser therapy should not be used on patients with the following conditions [12]:

❌ Cancer

Cancer patients should not undergo cold laser therapy, as the treatment, may stimulate the growth of cancerous cells and lead to the spread of the condition.

❌ Bleeding disorders

Patients with bleeding disorders or who are taking blood-thinning medication should not receive cold laser therapy, as it may cause excessive hemorrhage and bruise after treatment.

❌ Pregnancy

Pregnant women should refuse cold laser therapy, as the treatment may be harmful to the developing fetus and cause permanent damage. 

❌ Epilepsy

Patients with epilepsy may trigger a seizure if will using cold laser therapy. Also, if you have any other health condition that affects your nervous system, tell your doctor before using cold laser therapy.

❌ Photosensitivity

Patients who are photosensitive should not receive cold laser therapy, as the treatment may cause an allergic reaction and worsen their condition. 

❌ Cardiac pacemaker

Patients with implanted cardiac pacemakers should not undergo cold laser therapy due to the potential adverse effects of the laser energy on the pacemaker. There is a risk that the laser energy could disrupt the normal functioning of the pacemaker, which could lead to serious consequences for the patient.

Summary

Cold laser therapy is an effective treatment option for pain relief. It is a safe alternative to traditional pain relief methods such as surgery or medication.

Previously, this treatment could only be done in a clinic, but with the development of medicine, cold laser therapy devices are available for use at home. So if you have a busy schedule or like to be in control of your treatment, this method is for you. Another feature is that most devices can also be used to treat pets, so your entire family can get relief from pain.

In addition, this treatment is becoming more affordable as technology improves and more manufacturers enter the market. So if you are looking for an effective, safe, and inexpensive pain relief solution, cold laser therapy is a great option.
