How does laser therapy work for pain relief?

Laser therapy is a type of pain relief that uses a low-level laser (LLLT) to stimulate the body’s natural relief process.

Laser therapy is also referred to as photobiomodulation, low-power laser therapy, or soft laser therapy.

Laser therapy is different from other types of lasers, such as those used for surgery, which emit high levels of energy that can damage tissue. This kind of therapy uses low levels of energy that are safe, painless, and works by stimulating the body’s cells to promote healing.The lasers emit energy in the form of light that is absorbed by the cells in the body, stimulating them and increasing their production of ATP (adenosine triphosphate). It is an important molecule that plays a role in many cellular processes, including cell division and protein synthesis. By increasing the production of this molecule, cold laser therapy help to improve circulation, which can relieve pain and reduce inflammation.

What type of pain can be treated with laser therapy? 

Laser therapy can stimulate all types of cells, including muscles, ligaments, cartilage, nerves, etc., so a number of diseases can be treated with it. 

Some of the conditions that can usually be treated with laser therapy include:

  • Arthritis pain

Arthritis is a common disease that causes pain and inflammation in the joints. Laser therapy can help reduce both of these symptoms, as well as reduce hand stiffness and improve flexibility [1].

Take a look at LightStim, which can help relieve arthritis symptoms.

  • Back pain

Laser therapy can be effective in treating both chronic and acute back pain. It can help to reduce inflammation and speed up the healing process [2].

If you have back pain, take advantage of Venom Back, a device that provides soothing muscle pain.

  • Neck pain

Neck pain is a common condition that can be caused by various factors such as injury, poor posture, uncomfortable sleeping position, etc. Laser therapy can help reduce inflammation and pain by absorbing the light emitted. It stimulates the production of intracellular energy, which enhances the recovery processes [3].

  • Neuropathic pain

This type of pain is caused by damage to the nervous system. Laser therapy desensitizes the nerves by reducing levels of bradykinin, which promotes inflammation. As inflammation decreases, so do pain [4].

If you are experiencing symptoms of neuropathy in your hands, look to Flex Mitt, a device that can help you regain your mobility.

  • Postoperative pain

Laser therapy may be used to reduce pain after surgery. It impulses cellular activity, which means increased energy production and recovery process [5].

In addition to relieving pain, laser therapy can also help reduce inflammation and swelling and promote the healing of wounds and injuries, as well as relax muscles after a workout.

Best devices for pain management

IASO Cold Laser

IASO Cold Laser

Best post-workout recovery device

IASO сold laser is a safe, non-drug treatment for injuries, chronic pain, and degenerative conditions. The combination of longer (830 nm) and shorter (680 nm) waves allows you to influence deep and superficial tissues, stimulating the body’s natural repair process.

The device combines cold laser therapy with a massage function. There are three different modes in total, so depending on your condition, you can combine sessions using only a laser or vibration.

It is also worth noting that the device is very compact, but this does not impair its effectiveness. The size makes it easy to carry with you wherever you go without causing any inconvenience. Because of this, the laser is very fond of athletes, since the device can be applied to any place on the body for point heat and vibration effects.

To use the IASO, all you need to do is take an armband to tie around your arms, or adhesive patches (come in a set) to attach the device to any part of your body for immediate pain relief and muscle relaxation.

Venom Back

Venom Back

Best back pain relief device

Venom Back is a wearable wrap that uses cutting-edge laser treatment innovation to offer a muscle recovery treatment for low back pain and soreness.

The device dissipates heat using technology with four evenly spaced vibration blocks, providing deep back massage. Plus, the flexible design and included straps keep your device secure, so you don’t have to worry about slipping off.

As for vibration, you can choose:

  • Wave (in which the vibration passes through the four vibration blocks in short pulses);
  • Pulse (in which the entire device alternately turns on and off);
  • Constant (a steady stream of vibration). 

Based on your condition and for the best experience, you can use the option you want.

However, you should consider its bulky design, which is not suitable for on-the-go treatment, unlike the compact IASO cold laser. It’s also not the easiest device to use. Based on user reviews, the control panel is in an awkward position to manipulate, but its efficiency covers these minor drawbacks.



Best device for arthritis treatment

LightStim is an FDA-approved device that emits light energy to reduce pain. It uses patented MultiWave technology to emit four wavelengths of light (red — 630, 660 nm, and infrared — 855, 940 nm) at the same time, which impulses the body’s natural pain relief process for a quick effect. Based on this, this device is good for the treatment of arthritis. It is also a way to relieve muscle pain, stiffness, and muscle inflammation.

Another feature is that manufacturers don’t try to make LightStim multitask. They target each of their devices for one specific treatment thereby increasing its efficiency and safety.

However, keep in mind that the device is held in the hands and must work directly from the outlet, unlike the wireless devices Venom Back and IASO сold laser.

“My shoulders at times get so stiff and cause a lot of pain which makes it difficult to move around freely without feeling stressed out. I have tried different therapies, both medical and alternative, and the cold laser is one of the treatments that has given me quick relief. It was a game-changer for me and allowed me to live without limits!”

“The light therapy has helped me get my life back! After being told by two different orthopedic specialists that I needed a complete shoulder replacement due to an old injury I was confused. I’ve had bad results from surgeries and medications in the past, which caused fear because it’s risky. 

After trying out this new treatment, I was pleasantly surprised — it helped improve my range of motion and reduced pain so much. I’m now able to do most ADLS as well as return back to yoga!”

— Laura, AZ

“I have had this device for several years and I’m extremely happy with this purchase. It is an excellent solution for back pain, suitable for temporary relief from arthritis, and even caused me less jaw pain after oral surgery. It can also be used to treat bruises. You can’t go wrong if you want an easy-to-use therapy device at your fingertips.”

— Franck, FL
