LTU-904 and 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.

The LTU-904 is an infra-red laser operating at a wavelength of 904 nanometers. This invisible wavelength penetrates deeply into tissue (much deeper than the often used red laser operating in the visible red region).

LTU-904 Technical Data
Battery: inbuilt nickel metal hydride
Battery capacity: 5 hours
Charge time: 15 hours
Class 1 laser product
Weight: 375 grams
Length: 205mm(10 inches)

The LTU-904 operates with a peak power of 5 Watts. Its features include an in-built digital timer, and an audible warning device which sounds when the laser is operating, and two power settings.

The LTU-904 comes in a convenient carrying case with a mains adaptor/battery charger with a 13amp plug for the UK power supply, a reflector and an infra-red indicator test card. There is a manufacturer's instruction manual and a guidance booklet either for end-users or for therapists.

Designed for use at home or in a clinic, the entire package is light weight and completely portable. Its rugged construction means it can be taken wherever you travel.

How Does It Work?

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 reponses.

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.

What does that mean in practice?

Laser therapy is recognised and used worldwide for the treatment of numerous conditions and injuries in humans and animals. The 904 nanometer wavelength of the LTU-904 is especially effective in the treatment of:-

  • Lymphedema/lymphoedema
  • Slow healing skin wounds
  • Fibrous lesions
  • Sprained and strained ligaments
  • Tendon injuries
  • Muscle soreness

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

The LTU-904 can be used in conjunction with ultrasonic therapy, physiotherapy, chiropractic therapy and concurrent with most other therapy.

Full details of the treatment methods for various injuries are provided in the comprehensive owner's manual which is included with the unit.


Specific advantages of 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

Safety and Ease of Use

The LTU-904 The LTU-904 is a Class 1 laser and therefore eye-safe for patients and clinicians.

The LTU-904 is designed to be used as easily in the field as in the surgery.

The digital timer keeps track of the treatment time, and the audible beep confirms that the unit is working. The small portable package is hand-held with rechargeable batteries that give up to five hours of continuous use between charges, or the unit can be operated from mains power.

Each unit comes with a reflective shield. This innovation ensures that light reflected from the surface of the skin is reflected back to the tissue. This improves the effectiveness of the unit.
