INPA was founded in 2007, following a meeting at the World Physiotherapy 2007 conference in, Vancouver, Canada. It was formed from a core group of neurologic physiotherapists from Australia, Canada, Netherlands, UK, USA.
Mary Solomon (Canada) led the submission to become an official subgroup of World Physiotherapy. INPA was approved as a subgroup of World Physiotherapy at the 17th General Meeting of World Physiotherapy, in Amsterdam (2011).
The World Physiotherapy General Meeting reconfirmed INPA as a subgroup at the 18th World Physiotherapy General Meeting in Singapore (2015), and again at the 19th General Meeting in Geneva (2019) and the 20th General Meeting in Dubai (2023).
Membership dues were collected for the first time in 2020. INPA hired their first Executive Director (Ingrid du Toit) in 2022. At the INPA General Meeting in 2023, the member states voted to approve a new Constitution, to become incorporated, and to make the Vestibular and Movement Disorders SIGs a permanent part of the organization.
