High-Power Laser Therapy Improves Healing of the Equine Suspensory Branch in a Standardized Lesion Model.
- Journal Article
Summary
This study investigates the efficacy of high-power laser therapy in enhancing the healing process of suspensory branch ligament injuries in horses. The research indicates that treatment with multi-frequency high-power lasers significantly reduces the size and signal of the lesion, demonstrating their potential efficacy in promoting healing.
Methodology
The researchers applied high-power laser therapy in a standardized lesion model created on horses.
- They selected 12 warmblood horses and created lesions in all lateral suspensory branches.
- In each horse, they treated 2 of the 4 lesioned branches with a multi-frequency high-power laser daily for a duration of 4 weeks.
- Color Doppler ultrasonography was conducted during and after the treatment period to monitor the progress of the injury.
- At the end of the study, they euthanized 6 horses 4 weeks post-surgery (short-term group) and allowed the remaining 6 horses to rehabilitate until 6 months before euthanasia (long-term group).
Results
The study outcomes were measured against the size, signal, and time of recovery of the ligament lesions.
- The researchers observed that the transverse size of the lesion was significantly smaller after 2- and 3 months in the laser-treated branches.
- The expected enlargement of the lesion circumference and cross-sectional area over time was also significantly lower in the short-term laser treated group.
- The treated lesions demonstrated a significantly increased Doppler signal during treatment compared with the control.
- Upon examination with MRI, in both the short- and long-term groups, the cross-sectional area of the lesions was significantly smaller, and the mean signal was significantly lower in the treatment groups.
Conclusions
The experiments conducted in this study have provided evidence that high-power laser therapy can significantly improve the healing process of suspensory branch ligament lesions in horses. The therapy notably reduced the size and signal of the lesions over the course of the study, traits associated with healing.
