Summary
Prolonged cryotherapy using ice and water for 48 hours was safe and effective in cooling the equine distal limb. This method shows potential for managing various horse leg conditions.
Area of Science:
- Veterinary Medicine
- Equine Sports Medicine
- Therapeutic Modalities
Background:
- Current cryotherapy durations for horses are based on human medicine.
- Prolonged, continuous cryotherapy may offer therapeutic benefits if safe and well-tolerated.
Purpose of the Study:
- To assess the effects of extended, continuous ice and water application on the equine distal limb.
Main Methods:
- Four Standardbred horses received a 48-hour ice and water slurry application to the right forelimb.
- Continuous logging of hoof, ambient, and ice boot temperatures, with clinical observations every 2 hours.
- Lameness examinations were conducted pre-application and at 1 week, 6 months, and 1 year post-treatment.
Main Results:
- Continuous cryotherapy was well-tolerated by the horses.
- Significant cooling of the treated equine foot was achieved.
- No adverse clinical changes, lameness, or gross pathology were observed in the treated limbs.
Conclusions:
- Continuous ice and water application is a safe and effective method for cooling the equine distal limb.
- The sustained low temperatures achieved may benefit the management of various distal limb conditions in horses.
- This modality offers a potent therapeutic and prophylactic option for equine distal limb disorders.
