There was a recent ruling for the Pegasus World Cup race coming up on January 27th.
The information came from the protocols issued for the security, medication and treatments allowed for the race.
"Any shockwave therapy needs to be administered no later than 10 days
prior to the Pegasus. The attending veterinarian will need to make an
appointment with security and a report must be submitted to chief
examining veterinarian within 24 hours.
On race day, no treatments will be permitted, other than Lasix, for
specifically designated horses."
Let's just pull this apart and get to the real meaning. Because shockwave-type treatments have always had the reputation of masking injuries via an analgesic effect, they are frequently used to numb the nerves so a horse can't feel the pain or injury and race. Of course, this ignores the obvious, that more damage is being done and this is not in the long-term interest in the horses health. This is typically referred to by some trainers as "nerving" - mask and not cure.
There are unethical trainers and owners who have, in the past, do treatments a day before a race. They do these treatments because they are analgesic - they could care less about rules, fairness or the horses health.
It took us our first two years in business to help judges, veterinarians and officials that we simply do not have any analgesic component to our treatments. We only heal.
