About us

Flawless Motion Ltd has been a company since 2006 when Margie returned to NZ after working as team physio with the Great Britain Olympic Canoe and Kayak Team. We are located in Auckland, New Zealand, and braces can be fitted at the Auckland Shoulder Clinic, by making an appointment.

You can contact us by emailing, calling or posting on our Facebook page. We love to see where our braces have gone, and the adventures our braces have, so don't forget to post a picture of you wearing our brace on our instagram page or facebook!

Flawless Motion Ltd is owned and operated by Margie Olds, a physiotherapist who specialises in shoulder rehabilitation. Margie is passionate about helping people recover from shoulder injuries and designed this shoulder brace to support patients and help their recovery from shoulder injury and surgery. She has just finished her  PhD which investigated risk factors for recurrent shoulder dislocations. Her Masters thesis was investigating the tissue properties of people with shoulder instability (see her research papers below). She works clinically at the Auckland Shoulder Clinic where she has a specialist shoulder clinic and works closely with NZ orthopedic shoulder surgeons. The brace is use widely in New Zealand and Australia in conjunction with orthopaedic surgeons both before and after surgery. She speaks at shoulder conferences and seminars, both in New Zealand and internationally. She has worked at the Physio School at AUT University and is currently collaborating with a research team at the University of Kentucky.


Margie is passionate about providing optimal rehabilitation and is currently working with colleagues at the University of Kentucky to investigate clinical tests to ensure people safely return to sport after a shoulder injury. These tests (the Shoulder Arm Return To Sport (SARTS) tests 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
