The AEL IR 4400 Equine Laser is a Class 3B handheld cold / low-level laser therapy (LLLT) device, with three 904 nm infrared diodes (plus a 635 nm red aiming beam).
It delivers photobiomodulation: light energy is absorbed by cells (especially mitochondria), which can enhance ATP production, modulate inflammation, stimulate tissue repair, improve microcirculation, and reduce pain.
Because infrared light (904 nm) penetrates more deeply than visible red, the device is ideal for deeper soft tissues (tendons, ligaments, muscles, joints).
Thus, injuries or conditions involving soft tissues, inflammation, pain, and repair are the primary targets.
Soft tissue injuries: muscle strains, muscle tears, muscle tension
Tendon injuries and tendinitis
Ligament injuries, including suspensory ligament damage
Bowed tendons (i.e. tendon swelling / damage)
Joint disorders, arthritis, synovitis
Fractures (as adjunctive therapy, to support healing)
Pastern / fetlock injuries
Shin soreness (e.g. for racehorses
Back pain / stiffness / muscular back injuries
Cuts, wounds, abrasions (to accelerate healing)
Bruises, hematomas, swelling / edema
Inflammation, acute and chronic
Sprains, strains
Laminitis (this is a somewhat surprising claim)
Post-surgical recovery (to speed up healing) and to assist in pre-injury / preventive modality use.
Tendinopathy / desmopathy (superficial digital flexor, suspensory branch, etc.) β several clinical/retrospective reports and case series show improved ultrasound healing, reduced lesion size and better clinical outcomes after laser therapy used as part of multimodal treatment.
Muscle soreness & back muscle pain (epaxial muscles, exercise-induced soreness) β randomized / controlled short-term studies show objective changes in nociception and muscle activity after PBM (photobiomodulation). Evidence supports short-term pain/modulation effects.
Soft tissue injuries generally (strains, sprains, tendon & ligament injuries) β case series and veterinary practice reports commonly list benefit (reduced inflammation, faster functional recovery) when laser is used alongside rest, rehab and veterinary care. Clinical use is well documented
Wound healing / skin lesions β experimental and clinical reports indicate lasers can accelerate wound repair and reduce inflammation in soft-tissue wounds (used commonly in practice).
Joint conditions / osteoarthritis (adjunctive use) β some studies and practice reports show symptom improvement (pain, swelling) and functional benefit as an adjunct, but results vary by device, dosing and study quality
