LOW LEVEL AND HIGH INTENSITY LASER THERAPY (LLLT & HILT)
LOW LEVEL AND HIGH INTENSITY LASER THERAPY (LLLT & HILT)
Low-Level Laser Therapy (LLLT) is a therapy with maximum laser beam output power of equal to or less than 500mW whereas High Intensity Laser Therapy (HILT) typically have output power more than 500mW.

WHAT IS LOW LEVEL LASER THERAPY (LLLT)?
Low-Level Laser Therapy (LLLT) is also now known as Photo-Bio-Modulation (PBM) or Phototherapy, which is the modulation of the biological activity of the body through the controlled delivery of laser light. Phototherapy has been shown to affect cellular activity in the following ways: stimulates cell growth, increases cell metabolism, improves cell regeneration, invokes an anti-inflammatory response, promotes edema reduction, reduces fibrous tissue formation, stimulates nerve function, reduces the production of substance P, stimulates long term production of nitric oxide (NO), decreases the formation of bradykinin, histamine, and acetylcholine, stimulates the production of endorphins.
These photo-biological responses are largely responsible for the pain-relieving effects often observed in patients treated with phototherapy.

WHAT ARE THE APPLICATIONS OF LOW LEVEL LASER THERAPY (LLLT)?
The main clinical applications are various and in different fields like:
- Pain relief and management (Including neuralgia)
- Wound healing (Including ulceration treatment)
- Orthopedics (Including tendinopathy treatment)
- Podiatry (Including verruca Vulgaris and plantar and fasciitis treatment)
- Smoking cessation (Through non-needle acupuncture)
- Dermatology (Including acne and eczema treatment)
- Rheumatoid and osteoarthritis treatments
- Aesthetic applications (Including reduction of scarring and skin regeneration)
- Maxillofacial and dental applications Including TMJ dysfunction.

WHAT IS HIGH INTENSITY LASER THERAPY (HILT)?
High-intensity laser therapy (HILT) has been used more recently in the therapeutic protocols of musculoskeletal disorders. The main difference between HILT and low-level laser therapy (LLLT), is that the more powerful beams (power >500 mW) are irradiated to penetrate deeper, bringing a desired high amount of multi-directional energy to deep tissues in a short.
High-Intensity Laser Therapy (HILT) decreases pain in patients by up to 63%, reduces inflammation, and rapidly induces the deep tissue photochemical and photothermic effects that increase blood flow, vascular permeability, and cell metabolism.
Some side effects are present for High-Intensity Laser Therapy (HILT) like redness, swelling, and itching, Acne, Infection, reversible changes in skin color and scarring.

WHAT ARE THE APPLICATIONS OF HIGH INTENSITY LASER THERAPY (HILT)?
The main clinical applications are various and in different fields like:
- Sport Injuries.
- Soft tissue pain: trigger points.
- Shoulder Injuries: Sprained and dislocated Shoulder.
- Ankle Sprain.
- Herniated Disc and Sciatics.
- Cervical Pain and Stiffness.
- Lower Back Pain.
- Osteoarthritis of the joints.

IS THERE ANY NON-INDICATIONS FOR HIGH INTENSITY LASER THERAPY ?
There is no consistent contraindications for the application of HILT in general but it is safe to say that it is recommended to avoid the use of HILT in front of skin tissue disorders (infection, bleeding skin and cancer).
ARE BOTH Low-level laser therapy AND High-Intensity Laser Therapy SAFE TO USE?
There are relatively few contraindications for the use of therapeutic lasers (LLLT & HILT) and many of them are relative rather than absolute. A high degree of clinical knowledge and careful patient selection when considering laser therapy should minimize the risks.
