Flawless Motion Ltd is owned and operated by Dr Margie Olds, a leading physiotherapist specialising in shoulder rehabilitation.

Margie’s passion for helping people recover from a shoulder injury and surgery led to the design of the Flawless Motion shoulder brace system.

Margie recently completed a PhD researching the risk factors for recurrent shoulder dislocations. Her Masters thesis investigated the tissue properties of people with shoulder instability. Both lines of research support years of experience working hands-on with professional sports people and surgery patients.

Since its 2006 inception, the Flawless Motion system has been considered a market leader of shoulder rehabilitative care and further injury prevention, a position the range maintains today.

Widely used and recommended by orthopaedic surgeons, both before and after surgery, customers of Flawless Motion shoulder braces can be confident they are accessing a product developed and recommended by industry and medical professionals.

About Margie

Working closely with orthopaedic surgeons, Margie operates a specialist shoulder consultancy with the Auckland Shoulder Clinic, in New Zealand. She speaks internationally at shoulder conferences and seminars.

Margie has worked at the Physio School of AUT University and is currently collaborating with a research team at the Universoty of Otago (NZ) and the University of Kentucky (USA). She recently collaborated to write a book chapter on shoulder instability for clinicians. Her PhD and Masters papers are available for review below:

Before 2006, Margie spent time as team physio for the Great Britain Olympic Canoe and Kayak Team. Her contact with professional sportsmen and women continues across multiple disciplines including rugby and netball.

Please contact us by emailing, calling or posting on our Facebook page. We love to see our braces in action and welcome posts to the Flawless Motion Facebook and Instagram pages.

Return to sport

Margie is passionate about providing optimal rehabilitation and has published a number of research articles  which investigate the use of clinical tests to ensure people safely return to sport after a shoulder injury.

These examinations, referred to as “Shoulder Arm Return to Sport tests (SARTS)” are taught online to therapists at her website www.margieolds.com. Here are excerpts from an interview with Margie about the development of these tests:





Margie’s research (referenced below) focuses on improving the clinical impact of rehabilitation on people with shoulder injuries, particularly in the area of shoulder instability.
