Collaboration &

Our collaborative partnership with the University Paris Citè brings together leading researchers in the field of infant neuroscience and kinesiology, award-winning product designers and leading neonatal and pediatric physical therapy specialists.

Developing Joey

The original design dubbed 'CrawliSkate', was concepted by Dr Marianne Barbu-Roth and her colleagues at the Integrative Neuroscience and Cognition Centre, University Paris Citè.

Following an extensive collaboration and clinical trials, Daytot have developed a novel, research-based crawling product, which facilitates the training of reciprocal movement for infants at risk of motor delay.

"A product that promotes tummy time and crawling is to be applauded. The benefits of achieving the motor milestone of crawling for any infant, and especially a child at risk of developmental delay is vast and must be encouraged." Donna Murphy, Paediatric Physiotherapist, UK

The Science

Co-Inventor, Dr Marianne Barbu-Roth, explains, “Many studies have demonstrated that there is a link between how babies walk as newborns, and how they walk as adults. With this in mind, it emerged as essential to study the characteristics of this primitive form of walking, as well as links to environment and the importance of early training in children at risk of delays to their locomotor skills.

Following the significant findings of an initial test based on the findings of 60 2-day old typical babies, (Forma et al., 2019), Dr Marianne Barbu-Roth and her colleagues conducted a two-year study to test the efficiency of Joey, to stimulate the active propulsion and motor development of very preterm infants (24 – 32 weeks GA).

Joey Research

Our research has shown encouraging findings based on early motor training of extremely premature infants. The results show that early training has a positive effect in reducing the risk of gross motor delay when implemented from term and used daily.  

By providing extremely premature babies with the correct support to actively move at an early age, it is possible to encourage the early development of motor skills, to reduce the risk of early-years developmental delay.


Research Findings

Training with Joey started between 37 and 40-weeks GA. The study included 44 infants, separated into 3 groups, and receiving the following: Joey training of 5-minutes per day, training on a paediatric mattress in prone for 5-minutes per day and a no training (control) group.

  • Joey trained infants had better sustained sitting ability at 2 months
  • At 6 months, 50% of Joey trained babies could step with light hand support
  • At 9 months, 60% of Joey trained infants could crawl independently compared to only 20% in the Mattress and 38% in the Control group.
  • At 12 months, 40% of Joey trained infants could walk with five independent steps compared to only 14.3% in the Control Group. 
  • Joey trained babies developed better head control, better sitting, rolling, and standing postures, compared to the other groups.

Based on these findings, we propose that Joey training continues until 6 months (CGA) and is used as an early intervention therapy tool, to aid clinicians and encourage parents to actively participate in daily therapy at home as part of their routine.

We believe early
intervention is key

At Daytot, we believe that by intervening from day one, you can help babies at risk of delay catch up and make progress towards achieving age-appropriate developmental milestones.

Achieving Developmental Milestones

Early intervention services and therapies are important for babies who are at risk of a disability or delay as, when used effectively and as early as possible, they can have a positive impact on that child’s future development, including their -

  • Physical Development
  • Social Development
  • Emotional Development
  • Cognitive Development

Research shows that early intervention programmes and products that allow therapists and parents to work together, like Joey does, have a greater influence on a child’s future development.

Case Stories

Our case stories provide further insight into the potential therapeutic outcomes that Joey can provide babies with developmental delay. We have worked alongside highly specialised neonatal and paediatric therapists, to provide evidence-based case stories with babies with a wide range of conditions.
