Brief Report: Speech and Language Therapy in Children with ASD in an Aquatic Environment: the ASLT (Aquatic Speech and Language Therapy) Program.

Stamatis and team ran a small quasi-experiment with the kids, all with autism. Half got their usual speech-language therapy in a warm therapy pool. The other half got the exact same lesson plan at a classroom table.

Each child had two 45-minute sessions a week for eight weeks. Therapists targeted the same 20 vocabulary words for every child. They measured how many words each child could say or sign before and after the program.

The pool group learned an average of 14 new words. The classroom group learned only 8. That six-word gap is big enough to be statistically significant.

Parents also reported the pool kids used the new words at home more often. No child lost any skills after the program ended.

Caputo et al. (2018) showed a 10-month multisystem aquatic program raised adaptive behavior scores. Stamatis narrowed the lens: same setting, but zoomed in on speech gains. Together they show the pool can help both broad life skills and specific vocabulary.

Sparaci et al. (2015) boosted multisyllabic speech with computer visual feedback. Stamatis got a similar jump in words, but used water play instead of screens. Both studies tell us adding a novel modality can turbo-charge traditional speech drills.

Tucker et al. (2021) proved kids with ASD can learn safety skills in a pool. Stamatis adds that the pool itself—not just the swim goal—can be the therapeutic tool.

If you run speech sessions, try moving one or two trials into the pool, a kiddie pool, or even a water table. The buoyancy cuts distractions, the gentle pressure calms, and the play vibe raises motivation. Start with five target words, keep the same prompting sequence you use on land, and track data as usual. You may see faster vocabulary growth without extra staff or hours.
