Helping Horses Heal Using Therapeutic Laser Therapy

Animals have always held a special place in Kara Lawson’s heart. Whether cats, dogs, rabbits, chickens, or horses, Lawson’s connection with animals has brought joy to her life and influenced major life decisions.   

When she was 12, Lawson’s family moved into a renovated farmhouse. And horses were soon a significant part of her life. “I was lucky enough to be included in activities with friends who were active in the equine show community. I started taking lessons and trail riding as well as competing in local shows, and I was hooked,” Lawson says.  

Recognizing a Need

Lawson’s love and respect for animals led her to pursue a career as a licensed veterinary technician, and she graduated in 2019. And it was while working at a veterinary clinic that Lawson was first introduced to photobiomodulation—commonly known as therapeutic laser therapy—and was impressed by the results and success stories she observed in the small-animal setting.  

As she continued working at clinics, Lawson began to see the real need for laser therapy for horses.

“I took certification classes through the American Institute of Medical Laser Applications, which included medical laser safety, principles in the companion animal practice, and in the equine athlete,” Lawson says. She keeps current with all rehabilitation continuing education (CE) offered through the American Association of Veterinary State Boards as well as other Board-approved platforms. These CE credits cover rehabilitation, lameness, nutrition, and the management of arthritis and metabolic diseases. 

Along the way, Lawson identified a problem.

“I did my research and realized that in Maine, there wasn’t really anyone who traveled to offer laser therapy services,” Lawson explains. “Most people have these services at an equine clinic when working up orthopedic or other issues, but can’t follow up with additional treatments necessary to make a difference.” And although she observed successful rehabilitation services, none included laser therapy with a veterinary-grade Class IV laser.  

So Lawson began mapping out a course to open her own business focusing on laser therapy. Equipped with a business course and good relationships with medical laser device companies, Lawson transitioned to the role of business owner and officially opened Infinite Equine Laser Therapy, LLC in early 2022.   

The Benefits of Therapeutic Laser Therapy

According to The American Animal Hospital Association, “therapeutic laser therapy is becoming an increasingly available option that veterinary practices can offer their patients.” Properly trained veterinary technicians can handle laser therapy appointments (if state regulations permit). Both quite easy and noninvasive, laser therapy can be a helpful addition to many treatment protocols.

“[Photobiomodulation therapy] uses wavelengths of light to promote cell regeneration, pain relief, circulation, inflammatory responses, and release acupuncture points for body harmonization,” Lawson explains. She uses laser therapy to accelerate the healing process on wounds, arthritis, pinched nerves, muscle strains, orthopedics, postoperative incisions, dermatitis, and more. “In other words, nose-to-hooves, ears-to-tail. It complements other rehabilitation and bodywork services, and can be used prior, during, or after exercising.”

The key benefits observed quickly include pain relief (release of endogenous endorphins), decreased inflammation, better blood flow, faster wound healing, and nerve regeneration. For orthopedic and other chronic conditions, expedited healing time is often achieved with multiple laser therapy sessions.   

As a testament to laser therapy’s ability to speed up the healing process, Lawson saw incredible results after performing maintenance laser therapy sessions on a 5-year-old mare diagnosed with multiple suspensory tears. “A recheck ultrasound performed three months later showed very minimal tears, and in some areas, no tears at all,” Lawson says. “Most multiple suspensory injuries can take up to six months to fully heal on their own. Laser therapy cut this time in half, and my client is thrilled to be able to put her mare back to work.”  

Since starting Infinite Equine Laser Therapy, Lawson has helped a number of horses.

“Henry, a 7-year-old Thoroughbred with kissing spine, is one of my long-term patients, and he has had a great experience with laser therapy,” Lawson says. She was able to help Henry with pain and discomfort before and after surgery (interspinous ligament desmotomy and wedge ostectomy) and now provides treatment as a bimonthly maintenance.

“We saw incredibly fast results, including pain relief, incision healing, immediate hair regrowth, and scar reduction,” Lawson says. “Now muscle maintenance is performed as Henry makes his way schooling First and Second Level movements.”

How Therapeutic Laser Therapy Is Performed

Therapeutic laser therapy is considered safe in all equine disciplines, and specific treatment protocols are applied depending on the patient.

“A wand connected to the device is used with either contact or non-contact to apply the treatment,” Lawson explains. “Treatments range from one to five minutes. The Class IV laser applies the highest power at a shorter amount of time, making it ideal for all animal patients and for working around movement, discomfort, or temperament.” 

According to the AAHA, “the FDA divides lasers into four classes based on their power. Class III and IV are the most common lasers used in veterinary practice.”  

When a laser beam is directed to the patient’s tissue, the laser light is absorbed by the skin, muscle and bone. Penetrating at the cellular level, the light photons target water, hemoglobin, and cytochrome C oxidase within the bloodstream and mitrochondria. This stimulates cellular respiration, which plays a crucial role in wound healing, reducing inflammation, and managing pain. 

Veterinary-grade Class IV lasers are specifically designed with a myriad of fine-tuned options, protocols, and even acupuncture settings (using a targeted laser beam versus needles). Treatment duration and laser power are recommended based on factors such as whether the injury is acute or chronic, the type and size of wounds, and even coat color (light penetrates light and dark coats differently).   

And how do the horses react to laser therapy treatments? “In most cases, equines with orthopedic injuries, muscle maintenance, acupuncture points, and generalized pain areas show a great deal of relaxation and releases when working on the area,” Lawson says. “Deep breathing, yawning, closed eyes, stretching, and sleeping can be observed. Some with severe injury or discomfort tend to shy away at first, show signs of annoyance, and then releases usually follow it. If the horse has not experienced bodywork before, they may take a few sessions to express any outward feelings about it.“ 

Even without seeing the signs of relaxation and enjoyment, the laser is still doing its job in treating the area of concern.  

Katie Goodspeed, one of Lawson’s clients and owner of a 7-year-old German Riding Pony named Tigo, can attest to the advantages of laser therapy.

“Tigo has benefitted from laser therapy with everything from basic muscle work to reducing inflammation,” Goodspeed says. “Because it’s so noninvasive, Tigo finds it quite relaxing. We’re so grateful to have found Lawson and been able to incorporate this service into our monthly bodywork routine.”   

Although Class IV lasers are very safe to use—even on sensitive areas like a swollen sheath due to an insect bite—they are contraindicated for pregnant mares and for treating cancer.

Lawson also provides kinesiology taping, which “provides immediate circulation to an area of interest, releases muscle spasms and strains. It is also used as a lightweight stabilization tool and joint support. It is inexpensive and easy to apply.”  

Lawson balances a busy work/life schedule as her business grows. “I am very blessed to have an understanding family who knows my love and motivation for my business,” Lawson says.

And she makes sure to carve out time for her two horses—Wallace and Whiskey. Lawson and Wallace, a 13-year-old OTTB, enjoy showing at Second Level dressage. “Wallace came to me with a severe suspensory tear that took him out of eventing,” Lawson says. “I have used laser therapy on him in multiple areas, and he continues to move up the levels with no orthopedic limitations. I use laser to maintain muscle activity, hind end engagement, and relaxation through his poll.” 

Seeing the success of laser therapy in helping horses heal and experience noticeable improvement drives Lawson to keep pace with her active schedule. Lawson says, “I’m the ‘feel-good lady’… the horses are excited to see me because they know it’s time to relax on the crossties, relieve some pain, fix an issue, or simply enjoy themselves with no expectations.”
