Navicular Disease in Horses: Unveiling the Benefits of Red Light Therapy

Navicular disease, a chronic degenerative condition of the navicular bone in horses, presents a significant concern due to its intricate pathogenesis involving biomechanical and vascular components, particularly affecting breeds like Warmbloods, Quarter horses, and Thoroughbreds. This condition is responsible for over a third of chronic lameness in horses, characterized by symptoms ranging from pain, inflammation, to lameness in horses, making the diagnosis and understanding of navicular disease crucial for effective management. Engaging with treatments like anti-inflammatory measures and sports medicine has been traditional; however, the evolution of equine care is pointing towards innovative solutions.

Red light therapy emerges as a promising option, offering relief from the inflammation and pain associated with navicular disease, marking a significant advancement in equine red light therapy. As the quest for understanding and mitigating the signs of navicular in horses continues, incorporating red light therapy into a horse's care routine could herald a new era in equine health, providing an alternative to conventional treatments like joint injections and addressing soft tissue injuries. This article will delve into the science behind red light therapy and share success stories, broadening the horizons of treatment for navicular disease in horses.

Conventional Treatments for Navicular Disease

Medication and Corrective Shoeing

1. NSAID Administration and Pain Management: Navicular disease treatment often begins with non-steroidal anti-inflammatory drugs (NSAIDs) to manage pain and reduce inflammation. Medications like bisphosphonates, specifically Tildren and Osphos, have gained FDA approval for their effectiveness in treating the ongoing symptoms of navicular disease.

2. Corrective Shoeing Techniques: A critical aspect of managing navicular disease involves corrective shoeing. This includes rolled-toe egg bar shoes and wedge shoes, which help by encouraging early toe break-over and correcting the pastern axis, thus relieving pressure on the navicular bone and reducing tension on the deep digital flexor tendon (DDFT)

Surgical and Non-Surgical Interventions

1. Injection Therapies: Injecting the coffin joint or navicular bursa with corticosteroids or hyaluronic acid has shown to improve soundness in affected horses. These treatments target inflammation directly at the site of discomfort.

2. Surgical Options: In cases where medical therapy does not yield sufficient results, surgical options such as desmotomy of the collateral ligaments of the navicular bone or palmar digital neurectomy may be considered. However, these are generally seen as last-resort options due to their irreversible nature.

Supportive Care and Alternative Therapies

1. Hoof Care and Exercise: Regular maintenance involving hoof balance and trimming is essential. Therapeutic shoeing can also include techniques like removing shoes to improve blood flow. Controlled exercise and allowing maximum turnout are recommended to aid hoof biomechanics.

2. Adjunct Therapies: Additional treatments such as acupuncture and extracorporeal shock wave therapy have been utilized to provide relief and manage symptoms in horses with navicular syndrome, offering alternative options to traditional medication.

The Science Behind Red Light Therapy and Navicular Disease

Red light therapy (RLT) offers a non-invasive, promising approach to managing navicular disease in horses, a condition marked by inflammation and degeneration. The therapy utilizes specific wavelengths of light to penetrate deep into tissues, promoting healing processes at the cellular level. Here’s how it works:

1. Deep Tissue Penetration and Enhanced Circulation: RLT involves wavelengths between 620 nm and 700 nm, known for their ability to enhance circulation and promote healing. More importantly, near-infrared (NIR) light wavelengths from 800 nm to 900 nm can penetrate deeper, reaching muscles, bones, and soft tissues, crucial for treating conditions like navicular disease. This deep penetration helps in reducing stiffness and improving blood flow in the affected areas.

2. Stimulation of Cellular Activity: At the cellular level, RLT works by stimulating cytochrome c oxidase, a photo acceptor within the mitochondria. This stimulation increases cellular energy, thereby accelerating the healing processes. Enhanced cellular activity can lead to increased collagen production, formation of new capillaries, and potentially reducing scar tissue buildup during recovery.

3. Clinical Evidence and Case Studies: Various studies and case reports underline the efficacy of RLT in treating equine conditions. A 2020 study highlighted that both red and NIR light therapy positively affected the healing characteristics of distal leg wounds in horses, suggesting potential benefits for navicular disease as well. Moreover, case studies have documented improved outcomes in horses suffering from navicular disease when treated with RLT, showcasing reduced pain and inflammation, and promoting tissue regeneration.

This scientific backing highlights the potential of red light therapy as a significant adjunct treatment in managing navicular disease, offering a blend of deep tissue healing and cellular rejuvenation.

Case Studies: Red Light Therapy Success Stories

Red light therapy has demonstrated significant success in various equine health challenges, as evidenced by multiple case studies. Here are some notable instances:

1. Mr. Cornell's Recovery: A 26-year-old Welsh pony named Cornell showed substantial improvement in conditions related to chronic severe founder and starvation after receiving six weeks of red light therapy on his back and feet.

2. PeanutbButter's Improved Mobility: PeanutButter, a 24-year-old horse facing navicular issues, experienced enhanced mobility after just two weeks of using a red light therapy pad.

3. Comprehensive Healing in Multiple Cases:

4. A mare with navicular disease, calcification of the deep flexor tendon, and arthritis exhibited marked improvement in mobility and comfort after undergoing red light therapy, as recommended by her trainer.

• A Friesian mare with severe injuries including skull fractures and facial nerve paralysis showed significant recovery following red light therapy treatments.

• Remarkable healing was observed in a Quarter Horse gelding with a tibial fracture, ligament ruptures, and a fibula fracture after using the Equine Light Therapy pad.

• Complete recovery and a return to regular activities were reported for a horse with a torn distal sesamoid ligament after red light therapy sessions.

• A horse with a barbwire injury and another with a torn hamstring both returned to regular activities after significant improvements post-red light therapy.

These cases underscore red light therapy's potential in enhancing equine health, offering a non-invasive solution to traditionally challenging conditions.

Incorporating Red Light Therapy into Your Horse's Care Routine

Red light therapy (RLT) has emerged as a versatile and non-invasive treatment option for various equine conditions, including those associated with navicular disease. This therapy is particularly effective in managing joint pain, inflammation, and connective tissue injuries, making it an essential part of a comprehensive care routine for horses.

Treatment Protocol

• Frequency and Duration: Consistent treatment is key, with a recommended frequency of three to five sessions per week. Each session should last between 10 to 20 minutes, gradually increasing to about 30 minutes to ensure deep tissue penetration and effective healing.

• Safety and Efficacy: RLT is safe for horses, presenting no known side effects, which makes it a reliable option for regular use. Over time, this can lead to a more comfortable and relaxed horse, thereby easing the management of conditions like navicular disease.
