Lasers for veterinary

We are working together for animal health


Comparison of pain scores before and after low level impulse laser acupuncture with or without topical wound treatment in fourteen horses with acute laminitis (mean and standard deviation of pre-treatment pain scores = 3.43±1.02 and post-treatment pain scores 1.14±0.36, t- test= p<0.001)

Comparison of pain scores before and after low level impulse laser acupuncture with or without topical wound treatment in seven horses with chronic laminitis ; the mean and standard deviation of pre-treatment pain scores were 3.71±0.76 and post-treatment pain scores 1.14±0.38, t test=, p<0.001


Comparison of pain scores before and after LLLT acupuncture (LA treatment) with or without topical wound treatment for twenty one horses with either chronic or acute laminitis, (mean and standard deviation pre-treatment score 3.52±0.93 and post-treatment pain scores 1.14±0.36, paired t-test= p<0.001) -


Pictures 1-2: An 11 year old Hanoverian mare developed acute laminitis at the beginning of the pasture season. The mare was very sensitive on both front feet and had a pain score of 3. Rotation of the pedal bone was seen on radiographs (Figure 8c). Along with the LLLT acupuncture every 3-4 day with a 90 watt pulse laser, was administered for 3 minutes for 2 weeks. The owner continued topical LLLT at home for 2 more weeks. The hooves were expertly trimmed and the tip of the toe was reduced. Within 4 weeks the mare was sound with a pain score of 1 and the hoof was returning to normal. The horse returned to training 2 weeks later. Another radiograph of the hoof was obtained 4 months after the LLLT had been initiated and the pedal bone rotation had improved greatly
was now parallel to the sole. For one year now the mare has been successfully competing in dressage tournaments and has required no further treatment. (U.Petermann DMV)

The 11 year old Hanoverian mare with acute laminitis shown in pictures 1-2. The laminitis and rotation of the left front pedal bone was obvious on radiographs prior to LLLT (Figure 8c). Four months after LLT and corrective hoof trimming, the laminitis has
resolved and the pedal bone is resuming its normal position parallel with the sole. (U. Petermann DMV)

A 17 year old Trakehner mare with severe lameness from chronic laminitis of the left front foot. There was severe swelling and a supurative infection at the coronary band with a 12 cm separation from the hoof wall. Euthanasia was recommended by the
local veterinarian. The pre-treatment pain score was 5. The horse was hospitalized and received LLLT on acupoints and daily topical wound LLLT with a 90 watt pulse laser at a pulse rate of 292 and 9,592 Hz (Nogier’s former anti-inflammatory frequency A and Bahrs anti inflammative frequency) for 3 minutes for 2 weeks. Astringent wet hoof bandages containing acridine dye solution were applied daily. The horse was discharged and the owner continued the topical laser treatment daily for 4 more weeks. After 6 weeks all suppuration was gone and a 1.5 cm zone of healthy hoof wall was present at the original wound site and the pain score was 2. It has been 8 years and the mare continues to have a high quality of life, runs in the pasture without apparent lameness and can be occasionally ridden.

U. Petermann, Comparison of Pre- and Post-treatment Pain Scores of Twenty One Horses with Laminitis treated with Acupoint and Topical Low Level Impulse Laser Therapy, AJTCVM Vol 6, No.1, February 2011

Twenty one horses with laminitis were presented to the author for LLLT on acupoints and topically to encouraging microcirculation and demarcation of abscesses of the hoof. Before and after completion of a series of LLLT treatments, each horse was evaluated and given a pain score based on a pre-determine pain scale. The mean±standard deviation of pre- and post-treatment pain scores were compared with a t-test and were significantly different at p<0.001. Photographs of severe cases of laminitis in horses recommended for euthanasia are shown before and after LLLT. The results of this pilot study support the use of LLLT as a primary or adjunctive treatment option for equine laminitis and indicate the need for further exploration of LLLT for laminitis and other diseases in animals.
