| Sumario: | Low Level Light Therapy (LLLT) is a treatment method where red light or near infrared (NIR) light is utilised for treating a variety of disorders including wounds. Wound healing in horses may be slow, especially on the distal limb, and there is an interest to shorten healing times. The purpose of the present study was to investigate how treatment with pulsating visible red light (λ≈637 nm) and NIR light (λ≈956 nm) affects wound healing time in healthy horses.
A circular skin wound (Ø=2 cm) was created on each side of the neck in healthy horses (n=8). One of the wounds was treated using light treatment and the other was left untreated, serving as negative control. Treatment duration was 4 minutes and 40 seconds (red light 95 seconds, NIR light 185 seconds) and was performed once daily day 0-4, 7-11, 14-18 and 21-25. The irradiance was measured to 2.3 mW/cm2 for red light and 6.4 mW/cm2 for NIR light.
The wounds were photographed and evaluated using digital planimetry day 0, 1, 2, 3, 4, 7, 14, 21, 28 and 35. The wound area did not differ between treated and control group on any day. The wounds where visually inspected daily and the time to complete healing was recorded. Control wounds were judged as completely healed after a mean time of 49,0 days (95%Ci=35,462,6) and treated wounds after 51,8 days (95%Ci=38,7-64,8). This is a significantly shorter time to complete healing for control wounds (p=0,026). The evaluators were blinded in respect to which wound was treated.
The results of this study do not indicate any positive effect of light treatment on healing of experimental skin wounds in horses. |
