Topic:Rehabilitation
Rehabilitation for horses refers to the process of restoring physical function and performance following injury, illness, or surgery. This process often involves a combination of veterinary care, physical therapy, and specialized training techniques. Rehabilitation aims to promote healing, improve mobility, and prevent further injury. Common methods used in equine rehabilitation include controlled exercise programs, hydrotherapy, and the use of therapeutic modalities such as laser therapy and ultrasound. The effectiveness of these methods is evaluated through clinical assessments and performance metrics. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, outcomes, and advancements in the field of equine rehabilitation.
