Low Level Laser Therapy: Answers to Frequently Asked Questions

While unknown to many, the term laser is actually an acronym for Light Amplification by Stimulated Emission of Radiation. A laser is a device that produces coherent, collimated, and monochromatic light.

Low level laser therapy (LLLT) on the other hand is a light source treatment that is non-invasive and generates a single light wavelength. It emits no vibration, sound, or heat. Low level laser therapy is also referred to as biostimulation or photobiology.

In physiotherapy, low level laser therapy is used for reduction of inflammation, pain relief, and accelerated tissue regeneration. Some of the conditions treated using low level laser therapy include:

  • Osteoarthritis
  • Shoulder or hip bursitis
  • Sciatica
  • Tendonitis
  • Tennis elbow
  • Plantar fasciitis
  • Shoulder impingement syndromes
  • Low back disc generation
  • Reduction of volume and pain in lymphedema
  • Back pain treatment

If you are a candidate for low level laser therapy, consider it wise to know everything there is about the procedure so you can decide if it is indeed the best option for you. To help you out, below are answers to frequently asked questions about low level laser therapy:

How does low level laser therapy work?

In essence, laser light passes through the skin and stimulates the mitochondria (cell energy production center). The result is more energy, improved tissue growth, better cell communication, enhanced cell nutrition, and extended cell life.

Can I feel anything during low level laser therapy treatment?

You won’t be able to feel anything during low level laser therapy since the laser light won’t generate any heat or vibration. After the procedure, most patients report experiencing less pain, better joint movement, and improved strength.

What are some of the remarkable benefits of low level laser therapy?

Some of the notable benefits of low level laser therapy include healthy cell growth, circulation, tissue regeneration, wound healing, and immunity.

How long will the treatment last?

Many clinical studies have shown that positive results from low level laser therapy is often felt immediately. However, just like most therapies, it may require several sessions to fully resolve the underlying cause of pain and loss of function.

Typically, low level laser therapy sessions can last from 5 to 20 minutes. The total number of sessions required is typically from 8 to 15. However, the number of sessions needed will be determined on a case to case basis and will depend on key factors that will be evaluated by the doctor.

Will one session of low level laser therapy suffice?

While literature reports a single session of low level laser therapy can already generate significant improvement in strength, joint movement, and pain, long-term relief will often require several sessions.

Will low level laser therapy work for knee pain?

Low level laser therapy has been known to be effective in treating a number of conditions including knee pain secondary to osteoarthritis or injury. In addition, low laser therapy is also considered an effective treatment option for those with rheumatoid arthritis. Many patients have reported as much as 70 percent improvement after the treatment.
