Class IV Laser Therapy

Class IV Laser Therapy

What are benefits of Class IV Laser Therapy?

Class IV Laser Therapy has been shown to produce the following effects to an injured area:

  • Decreased pain and inflammation
  • increased bloodflow
  • increased oxygenation
  • increased ATP activity, which is the process required in the healing of tissues.

Class IV Laser Therapy has the ability to treat injured tissues that are deep and chronic. In laboratory and clinical studies, it has been shown to be effective for many conditions, such as osteoarthritis, Achilles tendinitis, plantar fasciitis, and low back pain, to name a few.

How is Class IV Laser Therapy different from previous laser therapy?

Compared to previous lasers available, Class IV Laser Therapy emits stronger, more intense laser treatment in a shorter amount of time than previous lasers available. It also emits more laser wavelengths that accelerate the healing of injured tissues.

What can I expect during a Class IV Laser Therapy session?

During a Class IV Laser Therapy session, you may feel a warm sensation from the laser and there should normally be no pain during or after a treatment. Patients can often feel immediate pain relief or it may take a cluster of treatments to feel its stimulating healing effects, depending on the type, severity and duration of the injury.

You will be given a pair of special glasses to wear to protect your eyes.

Laser therapy is not advised for patients who are pregnant or have a pacemaker.
