The hydrostatic pressure of the water blankets body parts for increased proprioception. More speedy movements use the viscosity and resistance of the water to help children organize their systems, improve their body scheme, and produce more coordinated movements. The buoyancy and viscosity of the water allows more time for movement responses and balance corrections thus enhancing motor learning. The water's support and fun naturally encourage independent movements that help build strength and endurance. Finally, the water is a natural place for socialization and language to emerge.
Therapists use a variety of techniques in the water.
NDT, sensory integration and soft tissue techniques can all be adapted for use in the water. Equipment can be very helpful when used with a specific purpose in mind. Appropriate flotation can support a child and allow for independent motion and self-propulsion. The appropriate toy can encourage hand use, socialization, language, or problem solving. The correct selection can help build strength, endurance, or improve swimming skills.
