Class 4 Laser: How It Works & What It Does?

A variety of laser therapy, including deep tissue class 4 lasers, are used around the world to produce laser therapeutic effects and help people improve their health.

Laser therapy provides a safe (approved by the FDA), painless, and drug-free way of reducing pain and stimulating healing. Since the invention of the class 4 laser, millions of people have it every year. However, many people still don't know how it works or what it does.

So in this article, you will learn all the basics of deep tissue class 4 laser therapy.

What is the class 4 laser?

Class 4 laser is any laser that has one or more laser beams with an output of 500mW or more (for example, 905nm or 980nm). A Class 4 laser is called a high-power laser because of its ability to emit high photonic energy in a short period of time and a hot laser because it can increase the temperature of the superficial tissue. It produces different effects in tissues, which encourages tissue healing and repair.

Class 4 laser has more energy compared to class 3B; hence, it penetrates deeper and produces results fast. During the deep tissue class 4 laser therapy, the patient may feel warmth on the skin due to the laser's high energy. Therefore, the laser must be handled carefully, and precautionary measures should be taken.

Does deep tissue class 4 laser therapy work?

Yes, like other forms of laser therapy, deep tissue laser therapy also works and produces healing effects.

It targets certain biological processes in the body in the injured area and stimulates blood circulation, which decreases pain and swelling associated with inflammation and improves the range of motion of the affected tendon, muscle, or ligament.

It increases the production of energy currency (ATP molecules); as a result, your body's natural healing process speeds up.

What is a class 4 laser used for? 

 Class 4 laser are used for acute as well as chronic issues. You can have the treatment to:

  • Treat pain associated with injuries

  • Increase the post-activity recovery rate for athletes and sports people.

  • Treat chronic as well as acute pain associated with neck pain, shoulder pain, knee pain, low back pain, elbow pain, sciatica, and arthritis

  • Control pain before and after a surgery

  • Prolong or reduce the need for surgery by diminishing pain

  • Speed up results of a treatment you are already having

There are many benefits to the class 4 laser. Some of these benefits include:

  • It is a drug-free treatment.

  • It does not cause the pain that surgeries produce. However, it does produce the sensation of warmth.

  • It reduces pain without any invasion.

  • It is approved by the FDA, which proves its authenticity and effectiveness.

How long does it take for deep-tissue laser therapy to work?

The answer to this question varies from patient to patient. A patient with minor neck pain may recover faster than a patient with chronic arthritis.

We can say that, on average, you may need 4 to 10 sessions of therapy to see results. The duration of a session can vary from 5 to 10 minutes. The number of sessions a person needs depends on:

  • The extent of the pain

  • The depth of the tissue

  • The size of the affected area
