Theralase - Healing at the Speed of Light

Why and how is cold laser therapy effective?

 

Much of the safety and effectiveness of cold laser therapy lies in its ability to trigger the body to heal itself. Penetrating into targeted tissue, laser light stimulates mitochondria in target cells to produce additional ATP, which fuels cell repair and regeneration. The laser simply jumpstarts the healing process and since the laser used operates within a specific wavelength range that is non thermal (the "therapeutic window"), there is no risk of tissue damage or other complications.

A wide variety of studies on the safety and effectiveness of cold laser therapy have been conducted by medical professionals from across the globe. Theralase also regularly conducts research and clinical trials to support the use of and discover new applications for laser technology.

 

Some recent topics include:

 

  • Laser Therapy in the Management of Chronic Myofascial Pain of the Neck
  • Action of Diode Laser in Orthopaedics and Traumatology
  • Effects of Laser Therapy in the Management of Lateral Epicondylitis
  • Acute Cervical Pain Relief with Gallium Arsenide (GaAs) Laser Radiation
  • Efficacy of Low Level Laser Therapy for Fibromyalgia

 

 

What is Low Level Laser Therapy (LLLT)?

 

Low Level Laser Therapy (LLLT) is the use of therapeutic (or cold) laser light to provide relief from pain, eliminate inflammation (swelling) or to repair damaged tissues. LLLT is entirely non-invasive and has a wide range of applications, from neural muscular skeletal conditions to wound healing to acupuncture treatments. Rather than destroying tissue, as with surgical (or hot) lasers, LLLT uses low intensity laser light energy to stimulate cells through a number of known cellular pathways in order to encourage tissue healing.

 

 

What is the difference between Class 3 and Class 4 lasers?

Explains the difference between Class 3 & Class 4 Lasers

 

 

How Low Level Laser Therapy (LLLT) Works

 

  • Laser light is delivered in the therapeutic window by monochromatic laser light in wavelengths ranging from 600 to 950 nm
  • Light particles also known as photons penetrate up to 10 cm into tissue
  • Photons are absorbed by electrons in photosensitive compounds, known as chromophores and cytochromes residing in the mitochondria increasing the rate of Adenosine Tri-Phosphate (ATP) production. ATP is the basic food source of cells derived from the phosphorylation of glucose in the mitochondria.
  • ATP fuels the cells and actuates the healing process - more ATP equals faster healing

 

Benefits of LLLT

 

  • Drug free, non-toxic and non-invasive
  • Extremely safe and virtually painless
  • Easy to apply with no side effects
  • Cost effective for practitioner and patient
  • Highly effective for patient (>90% efficacy)

 


 

FAQ

 

  1. How do therapeutic lasers work?
  2. What scientific documentation is there on Low Level Therapy (LLT)?
  3. How deep into tissue can a laser penetrate?
  4. Are there any harmful side effects or contraindications?

 

How do therapeutic lasers work? 

A: Therapeutic medical lasers heal tissue ailments by injecting billions of photons of visible and /or invisible laser light deep into tissue structures. Tissue naturally contains protein strands called chromophores and cytochromes located in the mitochrondria of a cell, which have the unique ability to absorb laser light energy and transform it into chemical energy for the cell. This chemical energy is utilized by the tissue to significantly accelerate the healing process and reduce pain in the body naturally.

 

 

What scientific documentation is there on Low Level Therapy (LLT)? 

A: There are thousands of published studies that describe the positive effects of laser therapy. These studies range from studies on individual cell types to in vivo double blind control studies. The areas of study range from wound healing to muscular skeletal conditions and have been conducted on different types of laser devices. Medicine is a very good medical database search engine that can provide abstracts and can sell literature. There are also many books on the subject. One very good text is "Low Level Laser Therapy - Clinical Practice and Scientific Background", written by Jan Turner & Lars Hode.

 

 

How deep into tissue can a laser penetrate? 

A: The depth of penetration of laser light depends on many parameters such as the laser's wavelength, the power, the type of device driver (pulse or continuous wave mode) and lastly the technique used. The higher the wavelength typically, the deeper the penetration; however, with wavelengths greater than 950nm the water in the tissue absorbs light and the depth of penetration is drastically reduced in addition to causing heat. Secondly, devices of greater power can provide better penetration. Thirdly, the peak power of the unit is the most critical factor in providing depth of penetration. Thus, devices which are true pulsed have better penetration versus continuous wave devices because they have greater peak power densities for superior photon concentrations at depth. *The TLC-1000 series of Therapeutic Medical Lasers can provide a direct penetration of tissue 5 cm into tissue and an indirect penetration up to 10 cm.

 

 

Are there any harmful side effects or contraindications? 

A: Some manufacturers produce devices with super-luminous diodes instead of true laser diodes because they are much cheaper to produce. Super-luminous diodes produce monochromatic light, but it is not coherent and hence scattered in all directions. Studies have shown that lasers are much more effective because of their superior photon density. The most common application for super-luminous diodes is for superficial wounds and surface dermatological conditions. Since these devices are very low powered, (approximately 5 to 15 mW rated and only 1 mW actual) and much of the energy they deliver is scattered, they will require much longer periods of treatment time. Most importantly, super-luminous diodes because of their low photon density will not be effective at delivering energy to tissues below the dermis.
