FROM BALMORAL to Byron Bay comes advice about curing back pain that is fit for a queen.
Internationally renowned physiotherapist Sarah Key has treated the British Royal family for more than 30 years along with thousands of Australian clients.
Her area of expertise is back pain and she sees it as an affliction that cuts across cultural, socio-economic and racial divides.
Ms Key was summoned to treat HRH Queen Elizabeth II after her Majesty developed back pain from riding side-saddle and sitting stock-still while saluting her troops.
"She really enjoyed a straight-forward Aussie approach which was about doing the job and getting out of there," Ms Key said.
Ms Key continues to divide her time between Australia and the United Kingdom, where she treats HRH Queen Elizabeth II, the Prince of Wales and Camilla Parker Bowles.
When she first moved to London at the age of 24 Ms Key never expected to lead such a "charmed life", but she now holds a trusted position within the Royal family.
"The English are funny. They take ages to accept you but once they do they never let you go," Ms Key smiled.
Ms Key is in the Northern Rivers to help everyday Australians understand how they can treat their own back pain.
Last night she addressed a packed lecture as part of her debut Sarah Key Talks Back series at the Byron Bay Community Centre.
Today she will host practical workshops on techniques for dealing with back pain.
She is also the author of three books - Back Sufferers' Bible, Back in Action and The Body In Action, and recently launched The Back App for iPhones and iPads.
Ms Key said back pain affects an estimated 90% of the Australian population.
Her advice is that back pain can be treated before it gets to a stage requiring surgery, but you need to listen to the signs your body is giving you.
Tickets to workshops are on sale from the Byron Bay Community Centre box office.
