The Otteroo: A Case Series Exploring Its Potential to Support Physical Therapy Intervention in Infants with or at Risk for Developmental Delay.

The objective of this case series was to examine the potential of the Otteroo as a tool to support physical therapy intervention in infants with or at risk for developmental disability. The Otteroo is a float with potential for use in aquatic therapy sessions or as part of a home exercise program. By tracking the amount of use and caregiver perception of the child's response, we aimed to generate an understanding of the Otteroo's potential as a family-based adjunct to physical therapy. Four children at risk of developmental delay participated in this study. The Otteroo was provided for four weeks, with recommendations for use. We used an activity log to track usage and collected survey data of caregiver perception of the child's response. Activity logs showed that use ranged from 3-7 interactions and a total of 40-99.5 min (x¯ = 54.88, SD = 29.75). The survey responses varied as to whether caregivers perceived their children enjoyed the experience. Future research should focus on finding effective methods of encouraging Otteroo use if efficacy of an intervention is to be tested. This initial work provides a foundation for future efficacy research with the Otteroo in children with or at risk for developmental delay.
