Clinical Trial Summary

The MaMa study aims to assess feasibility and validity of an infant wearable in a rural settings. Altogether N~100 infants will be recruited and measured multiple times at homes from age 6 months to age 18 months. Neurodevelopment of the infants is assessed at 18-24 months of age to compare motor development trajectories with the later neurodevelopmental outcome.

Description:

The MaMa study aims to assess the feasibility and validity of an infant wearable method to study young infants' neuromotor development in a low income setting. In this method, infants' motor abilities (e.g. variety of different postures and movement types) are measured using a playsuit equipped with movement sensors while the infant is freely playing in his/her native environment, such as home. The data recorded with the wearable sensors is analysed afterwards using an algorithm that quantifies individual movement and posture components as well as delivers holistic interpretations of infant's motor maturity. This method is developed in University of Helsinki, and it is already successfully used in clinical research projects in Finland, Denmark, Italy and USA. Use of movement sensors is common in other wellness and health applications, however wearables of this kind have not been used before for infant's neuromotor assessment. The solution has the advantage that it provides a fully objective and quantified representation of infant's motor activity in his/her native environment; which is not achievable with any of the currently used clinical assessment methods that are typically performed in the outpatient clinic environment.

The study will be conducted in rural Malawi, is East Africa. The investigators will assess the feasibility of the wearable method in a resource poor setting by running a pilot study on approximately five-to-seven-month-old infants. In the first phase, the investigators will assess technical suitability of wearable methods in 20 typically developing infants in the rural settings, and compare the results to those obtained from infants of the same age in Finland. In the second phase, the study will continue as a longitudinal follow-up of these infants and recruit a larger study group of Malawian infants (up to a total N~100), all of whom will undergo repeated assessment with the wearable method, every 6 weeks until the age of 18 months, or until they walk fluently. The results will support constructing motor growth charts for the Malawian infant population. At the age of 24 months, children's neuropsychological performance will be assessed using an assessment battery that was recently adapted for Malawian context; this will allow us to study how early motor development associates with later neurocognitive developmental profile.

There are three potential benefits from performing the study. First, to establish the practical feasibility and utility of a novel method for out-of-hospital neurological assessment in infants. Second, the project will establish functional motor growth charts for Malawian population to serve as a benchmark in any future intervention trial in comparable environments; these can be also compared to data from Finland. Finally, the project will allow assessing links between early motor and later cognitive development, a question with significant global health implications in all cultures.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Motor maturation level (BIMS)	BIMS (Baba Infant Motility Score) is a score that combines all recorded postures and movement activities to a holistic estimate of infant's motor maturation. BIMS has a scale from 0 to 100, with higher number being better.	The primary outcome BIMS is the level reached by 18 months of age
Secondary	Kilifi Developmental Inventory (KDI) score	KDI is a questionnaire based assessment of infants' neurocognitive development at 12-24 months of age. It is validated in the Malawi context. The scale is 0-70, with higher number being better.	24 months of age
