Action Observation Training to Improve Upper Limb Function in Infants with Unilateral Brain Lesion - a Feasibility...

Area of Science:

• Pediatric Rehabilitation
• Neuroscience
• Biomedical Engineering

Background:

• Unilateral Spastic Cerebral Palsy (UCP) affects infant upper limb function.
• Early intervention is crucial for improving motor outcomes in high-risk infants.
• Action Observation Training (AOT) shows promise but requires effective monitoring.

Purpose of the Study:

• To evaluate the feasibility of home-based Action Observation Training (AOT) for infants at high risk of UCP.
• To assess the integration and acceptance of sensor-based measurements during AOT.
• To explore the correlation between sensor data and clinical assessments of upper limb function.

Main Methods:

• Eight infants at high risk of UCP participated in a four-week home-based AOT program with caregiver assistance.
• Infants wore sensors during training sessions to collect upper limb movement data.
• Sensor data were compared with established clinical assessments: Hand Assessment for Infants (HAI) and Mini-Assisting Hand Assessment (Mini-AHA).
• Feasibility was assessed through training adherence and caregiver feedback.

Main Results:

• High training adherence and positive caregiver feedback confirmed the feasibility of AOT in this population.
• Wearable sensors were well-accepted by caregivers and infants.
• Sensor measurements demonstrated significant correlations with clinical assessments of hand function.
• Preliminary data suggest sensors can effectively track upper limb function during AOT.

Conclusions:

• Action Observation Training (AOT) combined with wearable sensor technology is a feasible and potentially effective intervention for infants at high risk of UCP.
• This combined approach offers a promising tool to complement standard care and monitor therapeutic progress.
• Wearable sensors provide objective, reliable data on upper limb function in pediatric rehabilitation settings.
