Summary
Low intensity laser therapy did not significantly improve wound healing in horses. Microscopic examination revealed no qualitative differences between laser-treated and control tissues, suggesting the device may lack sufficient power.
Area of Science:
- Veterinary Medicine
- Biomedical Engineering
- Tissue Repair
Background:
- Surgical wounds and tendon injuries are common in horses.
- Laser therapy is explored as a potential treatment to accelerate healing.
- Understanding the efficacy of low-intensity laser therapy (LILT) is crucial for clinical application.
Purpose of the Study:
- To evaluate the effect of low intensity laser therapy on wound healing in equine superficial digital flexor tendons.
- To compare microscopic tissue changes in laser-irradiated versus control wounds.
Main Methods:
- Surgical incisions were created in equine skin and superficial digital flexor tendons.
- One group of limbs received low intensity laser therapy treatment.
- Microscopic analysis compared incised laser-irradiated, incised-control, and nonincised-control tissues.
Main Results:
- No qualitative microscopic differences were observed between laser-irradiated and nonirradiated tissues.
- The study did not find evidence of enhanced wound healing due to the laser therapy used.
Conclusions:
- The low intensity laser therapy device employed in this study may not possess adequate power to influence wound healing processes in horses.
- Further research with devices of potentially higher power or different parameters may be warranted.
