Aquatics
Okay, let’s talk about the pool.
Aquatic therapy is my favorite thing to nerd out about. I stumbled into the magical world of aquatics on my very first fieldwork and never really got out. This page is for anyone who’s curious, whether you’re a student, a practitioner, or an academic: why the pool can work, how to get trained, and what the research says. (And no, it’s not for everyone. We’ll talk about that too.)
How I got here
From one fieldwork to a certification
I was introduced to aquatic therapy on my first Level I fieldwork. On my second Level II fieldwork, my fieldwork educator was in the process of getting certified in aquatics, and I was hooked.
I went on to certify with Aquatic Therapy University as an Aquaticist, both as a generalist and in pediatrics. Now my goal is to share why the pool can work, and to help more people explore it, consider it, and learn how it’s used.

Types of aquatic therapy interventions
A short introduction to approaches you’ll hear about. Each one has its own training.
Halliwick
A water-based approach developed by James McMillan that builds mental adjustment to water, balance control, and independent movement. Its therapeutic application is often called Water Specific Therapy.
Bad Ragaz Ring Method
Named for Bad Ragaz, Switzerland. The client floats with ring supports while the therapist provides stabilization and resistance through movement patterns, often based on PNF.
Watsu
A passive approach developed by Harold Dull, using shiatsu-inspired stretches and movement while the therapist supports the client floating in warm water.
Burdenko Method
Developed by Igor Burdenko. It combines water and land exercise and often uses deep, vertical water to work on balance, coordination, flexibility, endurance, speed, and strength.
Water Pilates
Pilates principles such as breathing, alignment, and core control, adapted to the support and resistance of the water.
Ai Chi
Developed by Jun Konno. Slow, flowing movements paired with deep breathing, done standing in shoulder-depth water. It draws on Tai Chi and Qigong.
Plyometrics
Jumping, hopping, and bounding drills done in water, where buoyancy lowers impact compared with the same work on land.
Aquatic yoga
Yoga postures and sequences adapted to the water, using buoyancy for support and the pool wall or equipment for balance.
Aquatic cognitive-motor training
Activities that pair movement with a cognitive task, such as counting, sequencing, or recall, so both are practiced at the same time in the water.
These are overviews, not instructions. Each approach has its own training, and the pool comes with real precautions and contraindications, so screening and a safe pool environment come first.
