Veterinary laser therapy, photobiomodulation

The requirements for successful veterinary laser therapy, laser irradiation

As already mentioned under "laser therapy", the natural holistic healing method is in the foreground for a fast and complete healing. All necessary functions and biofrequency programs are integrated in the RJ laser devices, e.g. for laser resonance therapy. 

Depending on the individual case, it can be used as a stand-alone therapy, as an adjunctive to common treatments and it can easily be combined with other therapies and medicaments. The RJ laser devices are made for application to individual points, reflex therapy and for local treatment of small and large areas.
RJ Laser has thousands of satisfied veterinary customers worldwide who have been using the laser devices successfully for many years and RJ develops the laser devices in close cooperation with leading therapists. Benefit from the experience of RJ and our customers.

Laser therapy, photobiomodulation is packed with research

Laser research/studies are, at least in the first step, always performed on animals. If this is positive, research will be continued on humans. So there is a lot of research available and for this reason alone, veterinary laser therapy is definitely a therapy component for almost every patient.

To learn acupuncture and laser therapy just join the international academies as IVAS, seminars of the European Academy TCM Laser Therapy, seminars of Dr. Uwe Petermann.

Laser beam/tissue

Laser beam penetration into the tissue

Radiation behaviour in the tissue and coat

Each tissue has a special optical behaviour. The laser beam is reflected, scattered, absorbed and transmitted depending on the wavelength and tissue. With increasing depth the laser energy/power decreases and can be compensated by higher power or prolonged therapy duration.
The crucial point in animals is the coat/fur and the color. If the fur is to tight, too thick, a large amount of the laser energy will be absorbed already before reaching the tissue and deeper layers. Therefor you either must shave the fur of the animal or use a special applicator which can push the hair away (RJ offers such applicator). If the color of the fur/skin is dark the laser beam will be absorbed in relation to the color tone.
As mentioned already use laser diodes with wave length of the "optical window".

Case report from Cindy Kneebone, Canada

American Bulldog, FS, born 1997.

Laser therapy in veterinary medicine is common since many years. Initial start of our vet laser therapy was in November 2007 - treated with a number of antibiotics and steriods, condition worsened. Referred to a dermatologist: 1 1/2 year using various antibiotics, steroids, topical tacrolimis and oral pentoxifylline.

Lesion was a deep, wet oozing ulcer under the tail approx 1 inch diameter. Began the UV vet laser laser treatment first on May 14th. Started at 10mins on tail and 10 mins on perineum. Repeated May 19th - tail and perineum was dry and dog didn't bother at it anymore. All medications stopped as of May 14th. Next vet laser treatments with UV lasers May 20, 25, June 5, 22, and July 21st (last vet laser treatment - healed).

11 year old yellow lab. 

Came to us from the Emergency clinic, from dermatology.  Been through a number of therapies including a number of antibiotics.  Diagnosed in May 2010 with methicillin restistant Staphylococcus pseudointermedius.  Prognosis was poor for this patient.  She came to us in fear of losing her dog and the fear of this pet being contagious to the population in general.  Two weeks with the use of the ultraviolet laser twice a week for 10 minutes. See the healing we achieved within two weeks.  The skin was also thickened and has become nearly normal thickness as our treatments continue.

Wound management (chronic healing disorder)

The horse suffered under serious wound healing disorder with periostitis after traumatic injury. The process had a chronic approach and the horse was almost unable to move his leg. Dr. Susannne Braun decided to use the laser intensively as soon as she received the patient. The therapy was successful, led fast relieve and complete healing (03.18.-05.05.2005).

Abstract
Chronic non-healing cutaneous wounds are often vulnerable in one or more repair phases that prevent normal healing and pose challenges to the use of conventional wound care modalities. In immunosuppressed subject, the sequential stages of healing get hampered, which may be the consequences of dysregulated or stagnant wound inflammation. 
Photobiomodulation (PBM) or low-level laser (light) therapy (LLLT) emerges as a promising drugfree, non-invasive biophysical approach for promoting wound healing, reduction of inflammation, pain and restoration of functions. The present study was therefore undertaken to evaluate the  photobiomodulatory effects of 810 nm diode laser (40 mW/cm2; 22.6 J/cm2) with pulsed (10 and 100 Hz, 50% duty cycle) and continuous wave on full-thickness excision type dermal wound healing in hydrocortisone-induced immunosuppressed rats.
Results clearly delineated that 810 nm PBM at 10 Hz was more effective over continuous and 100 Hz frequency in accelerating wound healing by attenuating the pro-inflammatory markers (NF-kB, TNF-α), augmenting wound contraction (α-SM actin), enhancing cellular proliferation, ECM deposition, neovascularization (HIF-1α, VEGF), re-epithelialization along with up-regulated protein expression of FGFR-1, Fibronectin, HSP-90 and TGF-β2 as compared to the non-irradiated controls. Additionally, 810 nm laser irradiation significantly increased CCO activity and cellular ATP contents. Overall, the findings from this study might broaden the current biological mechanism that could be responsible for photobiomodulatory effect mediated through pulsed NIR 810 nm laser (10 Hz) for promoting dermal wound healing in immunosuppressed subjects.

Local therapy is important, but the indirect stimulation as it is for ear acupuncture as well (especially for inner organs which are difficult to irradiate directly). The ear is perfect to stimulate organs and body parts indirectly (ear-brain-organ). It is easy to perform and will improve the healing process. Procedure:

  1. Detect (palpation or electronically) the most painful spots and/or areas which show uncommon color e.g. redness, vessels, pimples, dandruff
  2. Irradiate these points/zones additional to the local therapy. Each point requires just a few seconds, approximately 3-5J or according to the pulse reaction (RAC)
  3. Biopolar therapy: The Physiolaser offers the possibility to treat direct/indirect at the same time, e.g. ear points and local organs body parts.

Pulse controlled laser acupuncture for best results

Just like in human medicine, pulse-controlled acupuncture is the "royal discipline" and will enable the most accurate diagnosis and consequently determine the best therapy. Dr. Uwe Petermann is the pioneer of pulse controlled acupuncture and we highly recommend his book "Pulse controlled laser acupuncture" (PCLAC).

General vet recommendations for laser therapy

A special position for cl. 3B is acupuncture and ear acupuncture (more suitable because of the small beam exit). Laser therapy devices cl. 4 are better for diseases that require heat, also in terms of moxa. It is also ideal for large area treatment and deep regions as joints, internal organs etc. (acceptable therapy duration). 

How to reach the target tissue?

Depending on the individual conditions of the animal the laser beam can reach the target tissue or will be absorbed by color/pigmentation or particles. The main barriers are:

  1. Coat/fur: Thickness and volume could absorb high amounts of energy!
  2. Color of the fur and skin: Dark pigments will absorb high amounts of photons (less energy supply)

Skin without hair, e.g. mouth, wounds are perfect to irradiate because the energy of the laser beam can easily reach the cells. In case the skin is dark the beam will heat up the skin easily. Therefor reduce the duty cycle and/or move the probe. The suitable wavelengths with low absorption are between 650/808-915 nm. Skin covered with fur is always difficult to treat because the hair will absorb parts of the laser energy. A special probe tip can be helpful to remove the hair. RJ offers a variety of solutions as point applicators and brush probes. Note:

1. Deep target tissue needs more time and/or higher power to supply satisfactory amounts of energy

2. Pressure offers better photon supply (less water in the tissue).
