RACING Victoria Limited Stewards have confirmed that the investigation into the treatment of Bauer in the lead-up to the 2008 Emirates Melbourne Cup relates to extracorporeal shock wave therapy (ESWT). ESWT is used to treat musculoskeletal problems in racehorses. It does this by creating pressure waves that stimulate specific sites in the body. Research has shown that shock wave therapy can result in locally decreased pain sensation (analgesia) after treatment. Potential exists for horses to race while experiencing this post-treatment analgesia. It is understood Bauer underwent the treatment on the Thursday before the 2008 Melbourne Cup for pain in the hind-quaters. The stewards are concluding their investigation and will make a statement regarding the outcome of the investigation at a media conference at 1:30pm on Thursday. Under the Australian Rules of Racing it is prohibited for a horse to undergo such treatment within seven days of a race. Following a National Chairman of StewardÃ¢Â€Â™s conference in 2004, Rule 64H, which deals with shock wave therapy, was adopted. The Rule states: Ã¢Â€ÂœA horse that has been subjected to any form of shockwave therapy shall be ineligible to race or take part in any trial in the seven days following such treatment.Ã¢Â€Â It is the first inquiry of its sort in the Melbourne Cup's 147-year history. If connections are found guilty, Bauer would be disqualified, costing the English stallion's owners, which include former Australia cricketer Simon O'Donnell, $835,000 in prizemoney. No licensed person in Victoria or New South Wales has been charged under Rule 64H since it was introduced.
