Equine therapy a promising PTSD treatment, but research hard to come by

It's been about a year since veteranOwen McElroymet his horse, Ben, in an equine therapy pilot project at Sari Therapeutic Riding.

These days, McElroysays his busy work and family life keep him from spending much time at the stables, but that he still draws on what he learned in the project to deal with his post-traumatic stress disorder (PTSD).

"Every day I'm able to use some of the tools I gained in some aspect or another: self-awareness, being more objective and less emotional," said McElroy, who spent 14 years in the military, and now works in operations for a local recycling company.

Although anecdotal cases like McElroy'smake a strong case for equine therapy, Brescia University Collegeresearcher Anne Barnfield says trying to establish solid research on the subject is an uphill battle.

It's mostly a question of research fundingand getting access to it isn't easy, said Barnfield, who worked on the pilotproject that McElroy took part in.

"We're kind of caught in a negative cycle," said Barnfield, adding that because equine therapyisn't yet a validated therapy, funders don't want to pay to study it. But without funding to study the project, researchers like her can't prove whether it's valid or not.

At this time, the only treatments with 'strong evidence' behind them arecognitive processing therapy andrepetitive transcranial magnetic stimulation, said Peter Hall, a clinical psychologist and associate professor at the University of Waterloo. 'Strong evidence' here means evidence backed up byrandomized controlled trials.

Equine therapy could give patients another treatment option if it is proven effective, Barnfield said.It may even prove to be a better choice for some groupsfor instance, patients who prefer working outside to talking with a therapistin an office.

"There are arguments thatthis might work better with a population, but we'd need to find that out," she said.

"Any kind of thing that people are trying to promote or sell they can say this is effective. If we're going to be scientific about it we should measure this,so people aren't just clutching at straws and trying anything."

New round of research set for the fall

This year, Sari Therapeutic Riding tried to host another round of the project, but couldn't find enough participants to make the finances work.Instead, they'll do two half-day versions of the project in the fall, said Sari Therapeutic Riding executive director Diane Blackall.

Barnfield said she still plans to study the abbreviated version of the project,to try and find out whether short-term equine therapy still has an impact. She is currently in the process of getting approval from her university's research ethics board.

"I'mreally curious as to whetheran intensive, shorter term session would have an effect," said Barnfield, who said she suspects it will.

"Even if it turns out that the effect isn't great, well at least we know that."
