Low Level Laser Therapy (LLLT)

What is Low Level Laser Therapy? 
Low Level Laser therapy (LLLT) is the treatment of various conditions using laser to bring about a photochemical reaction at a cellular level. The laser light penetrates into tissue where it is absorbed by cells and converted into energy that influences the course of metabolic processes.  LLLT can also be called cold laser therapy.

The LTU-904 models are infra-red lasers operating at a wavelength of 904 nanometers with a peak power of 5 Watts. This invisible wavelength penetrates deeply into tissue (much deeper than the often used red laser operating in the visible red region).  

           Advantages

          Specific advantages of the LTU-904 laser therapy include:-

• Painless and often immediate analgesic effect at the time of treatment
  Dramatically shortened recovery time with rapid reduction of swelling and inflammation
• Non-invasive and patient friendly treatment
• The LTU models are Class 1 lasers and therefore eye-safe for patients and clinicians.
  
  
  Responsive Injuries
  
  Laser therapy is recognised and used worldwide for the treatment of numerous injuries in humans and animals. The 904 nanometer wavelength of the LTU models is especially effective in the treatment of:-

• Lymphedema/lymphoedema
• Slow healing skin wounds
• Fibrous lesions
• Sprained and strained ligaments
• Tendon injuries
• Muscle soreness
  
  The LTU models can be used in conjunction with soft tissue therapy, ultrasonic therapy, physiotherapy, chiropractic therapy and is concurrent with most other therapies.
  
  
  Treatment of Injuries
  
  Treatment using the LTU models is usually in contact with the skin, directly onto the injury. When treating skin wounds, the units are used in non-contact mode.
  
  The time and frequency of the treatment varies depending on the type of injury and its condition. This may be as short as one single treatment of a few minutes to many treatments of 5-10 minutes.
  
  The Laser Effect
  
  Infra-red energy is absorbed in the cell membrane, where it induces a photophysical reaction which directly mediates the membrane potential, resulting in the intra and extra cellular transport of photoproducts.
  
  The ultimate photoresponse is cellular proliferation.
  
  The cellular mechanisms are immediate, and are followed by secondary local reactions as the photoproducts interact with surrounding cells and tissue, producing such documented effects as enhanced blood and lymphatic flow, and photomediated neural responses. The local reactions are followed by systemic effects as the photoproducts are carried by the blood and lymphatic systems around the body, and the photomediated neuroresponses take effect.
  
  Treated skin wounds show the following reactions:-
  
  

• Reduced scar formation
• Reduced pain and inflammation
• Increased collagen and reduced cellular substances
• Increased epithelial activity
• Increased capillary blood vessel formation
