Objective: To evaluate the effects of low level laser therapy (LLLT) on healing of full thickness symmetrical skin wounds in horses. LLLT is a therapeutic modality using the application of light, usually a low power laser or light emitting diode in the power range of 1 mW to 12 W that, in practical terms, promotes tissue regeneration as well as reducing inflammation and pain.
Conclusion: LLLT increased the rate of wound healing.
