ATU was once told that OTs "do not provide aquatic therapy services". Below, you can read our (comprehensive) response.
Aquatic therapy is a water-based therapeutic tool that is taught in OT school as a hands-on procedure; used in practice by occupational therapists/assistants; and routinely reimbursed by payers.
Since 2010, Aquatic Therapy University/ ATU Aquatic Therapy Seminars have provided aquatic education across the world (Canada, The Netherlands, Puerto Rico, USA, Malaysia, Hong Kong, Singapore, India and more).
In 2014, ATU was the first provider to obtain value added CEU credit for our aquatic therapy courses through the Federation of State Boards of PT, a national entity.
Since 2017, the Hospital Authority of Hong Kong has educated all their PTs and OTs using our 4-hour digital introductory training. The same group sent 4 therapists to train with ATU yearly for a 10-day training each year, until the pandemic interrupted travel. These are just examples.
Occupational therapy has been performed in water for over 50 years. Here is a very short primer for your edification.
