Aquatic Therapy for Children with Disabilities

What is Aquatic Therapy?

Water supports much of the body's weight, so a child who struggles to stand or walk on land may be able to move more freely in a pool. Water also adds gentle resistance for strengthening, and warm water can help relax tight muscles. Many children find the pool calming and fun, which can boost motivation.

Sessions usually take place in a warm therapy pool. The therapist may work on walking, balance, kicking and reaching, breathing control, or water safety skills, depending on your child's goals. Methods such as the Halliwick concept focus on balance and control in the water.

Aquatic therapy is different from swim lessons. Therapy targets medical or developmental goals set by a licensed therapist. Adaptive swim lessons teach swimming and water safety. Both can be useful, and some programs combine them.

Who is it for?

Who provides it?

A licensed physical therapist (PT) or occupational therapist (OT), sometimes assisted by a PT or OT assistant. In Illinois, verify the license through IDFPR. Some therapists hold extra aquatic credentials such as the ATRIC from the Aquatic Therapy and Rehab Institute, but that certification is voluntary and, as the institute itself states, does not make someone a therapist. Adaptive swim instructors can teach water skills but do not provide therapy.

What do families and practitioners report?

Parents often say the pool is where their child finally moves with freedom and joy, and that gains in the water carry over to land. Families of autistic children frequently report that the water is calming and that their child becomes more regulated and social. Therapists value that water lets children practice movements they cannot yet do on land.

Does it work? What the research says

For cerebral palsy, a 2020 overview of CP interventions (Novak and colleagues) rated hydrotherapy 'yellow' (weak positive) as an add-on to task-specific motor training. A 2025 meta-analysis of 15 randomized trials with 369 children (Pauluka and colleagues, Child: Care, Health and Development) found low-quality evidence that aquatic physical therapy gave slightly better gross motor results than land-based exercise, and concluded overall that aquatic and land-based exercise appear comparable.

For autism, a 2026 meta-analysis in Frontiers in Behavioral Neuroscience (Xin and colleagues; 6 studies, 159 children) found aquatic exercise may improve overall autism-related symptoms and behaviors, but evidence for motor and other specific outcomes was limited and inconsistent. Across conditions, studies are small and often at high risk of bias.

Is it covered by insurance in Illinois?

When provided by a licensed PT or OT, aquatic therapy is often billed as physical or occupational therapy and may be covered by commercial insurance and Illinois Medicaid/All Kids if it is medically necessary. Plans may limit the number of visits or require prior authorization. For state-regulated Illinois plans, the autism coverage law requires coverage of PT and OT for autistic children under 21, though it does not specifically name aquatic therapy. Adaptive swim lessons are usually not covered, and pool-based therapy is uncommon through Early Intervention or school IEPs.

What to consider and ask

• Confirm the therapist is a licensed PT or OT and ask about their aquatic training.
• Ask about pool temperature, access (lifts or ramps), changing areas, and lifeguard coverage.
• Set motor or functional goals and ask how progress in the pool will be measured on land.
• Ask whether water safety skills will be included, especially if your child wanders.
• Check medical issues first, such as seizures, skin or ear infections, and continence needs.
• Consider combining therapy with adaptive swim lessons for long-term fitness and safety.
