CareToy - A Modular Smart System for Infants' Rehabilitation at Home Based on Mechatronic Toys

Overview

Stroke and other neurological conditions affect the population of infants in percentages that cannot be considered marginal. Preterm infants are the highest infants at risk for neurological damage. Currently, infants have rehabilitation sessions few times a week in rehabilitation centres but according to basic neuroscience it would be necessary to provide them with an early, intensive and multiaxial intervention. One option to reduce the cost of the entire European Healthcare System while increasing the practice of rehabilitation is to devise therapies and technologies that can be administered at home by caregivers and telemonitored by rehabilitation staff. The aim of this proposal is to promote early intervention in the first year of life and to reinforce therapy by "CareToy": a portable low cost smart system telemonitored thus augmenting the clinical effectiveness of the therapy while reducing the cost. The smart system is based on a common baby gym, composed of different modules: a) an instrumented baby gym with mechatronic hanging toys, so that the infants' actions on the gym can be measured and stimulated, b) a vision module, for measuring and promoting infants' attention and gaze movements and c) a sensorized mat for measuring and promoting postural control. Each module will also incorporate built-in signal processor, memory and wireless communication. A fourth telerehabilitation module completes the system that allows the system to remotely communicate with the rehabilitation staff for monitoring and assessing the rehabilitation techniques. CareToy and the effectiveness of home rehabilitation based on this system will be validated by clinical trials on at least 50 preterm infants. The result of this project could have a large impact. CareToy may become a commercial product, manufactured on a large scale and distributed not only in rehabilitation centres but also at homes, sold or rented by the Health Care System to families as a therapeutic tool for care intensity.

Study population will be made up of premature infants recruited at the local Department of Neonatology. The eligibility of infants, i.e. children who meet the criteria for inclusion and exclusion, will be evaluated by the Neonatology team. Recruitment should take place after discharge from Neonatal Intensive Care Unit (NICU) until the age stated by inclusion criteria and will begin with the signing of the participation agreement by the parents. During the recruitment extensive perinatal data will be collected from medical records. Each clinical centre will maintain these data in an internal database storing. Every child will be evaluated on the basis of a standard neurological examination supplemented by movement analysis on video recording using Prechtl's Method Qualitative Assessment of General Movements. The sample will be randomized in two groups in order to compare the effectiveness of the CareToy intervention program vs standard care on motor, cognitive and visual development. We designed the study as randomized clinical trial. The sample size was calculated on the basis of the primary outcome measure (Infant Motor Profile \[IMP\], see Outcome measures). Before the starting of the RCT we have planned a short pilot phase where few infants in order to assess the feasibility of the CareToy training and to tune and set-up the CareToy system and the rehabilitation packages. These cases will follow the same steps planned for the RCT.
