Veterinary staple
What happens, therefore, if a horse is administered shockwave treatment immediately before a race to dull pain and mask injury?
This is the sort of question that has been asked about shockwave machines ever since they began to become a veterinary staple at the turn of the century. But, where does the issue lie now? What do we know about the science behind shockwave machines? And what have regulators done to investigate and govern their use?
“There’s still not a test for it,” said Mary Scollay, Kentucky equine medical director, and someone who has long been outspoken of her concerns about the instrument.
“While it’s possible to achieve reasonable regulation of the use of the instrument at the racetrack and under a regulated environment, it’s use at private farms, training centers, locations outside the track is virtually unregulated regardless of what the rules actually say,” she added.
