Development of Motility and Cognition in Infants

Study Overview
=================
Brief Summary
-----------------
PILKE study uses wearables for assessing motor development in infants in order to define functional growth trajectories in the normal infants and infants at risk of neurological compromise. In addition, PILKE studies correlation of early motor development to later neurocognitive development.

Detailed Description
-----------------
PILKE study builds on the recent development of an infant wearable, MAIJU, a multisensor garment that can be used to quantify infants posture and movement patterns out-of-hospital. The study will recruit typically developing infants (control group) and infants with an identified or suspected risk of neurodevelopmental compromise, as well as infants undergoing orthopedic follow-up for hip issues. Infants will be examined and treated according to clinical routine practise, while MAIJU and other novel measures are added to monitor aspects of neurodevelopment. Recordings with MAIJU will be done every 6-8 weeks from about 5 months to 18 months of age, and the neuropsychological outcome is assessed using Bayley scales at two years of age. The study is observational by design, and the trajectories of motor performance are compared to other clinically identified measures of development.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| typically developing infants<br>recruitment at 5-8mos of age; infants are considered typically developing if they are born at term age with no neurologically significant medical history, and they are not medically followed up for a suspicion of such. The benchmark for this is taken from the nationally harmonized pre/postnatal screening practise. | |
| neurodevelopmental concern<br>recruitment at 5-8mos of age; infants are recruited from the outpatient clinic in the New Children's hospital (NCH). They have either a known perinatal risk factor (e.g.stroke, HIE, meningitis), or they are referred to pediatric neurologists at NCH due to a suspected delay or deviance in neurodevelopment. | Other: physiotherapy<br>* Some infants will receive physiotherapy as a part of their clinically indicated care.<br>|
| hip dysplasia concern<br>recruitment at 2-6 weeks of age after perinatal clinical suspicion of hip dysplacia. These infants may be left out of follow-up (mild), or treated by orthopedic clinic with a soft brace (moderate) or a stronger cast (sever) | Device: brace<br>* Some infants in the hip dysplasia group will receive brace and/or cast as a part of their clinically indicated care<br>* Other names: cast;|
