Leg Movement Rate Pre- and Post-Kicking Intervention in Infants with Down Syndrome

Area of Science:

• Developmental pediatrics
• Motor development research
• Clinical intervention studies

Background:

• Infants with Down syndrome (DS) often exhibit delayed motor development, including atypical kicking patterns.
• Early intervention is crucial for improving motor outcomes in children with DS.

Purpose of the Study:

• To investigate the efficacy of a home-based kicking intervention in enhancing leg movement rate in infants with DS.
• To compare the leg movement rates of infants with DS post-intervention to those of typically developing (TD) infants.

Main Methods:

• Nine infants (3-5 months) with DS participated in an 8-week, home-based kicking intervention using a specialized toy.
• Leg movement rate was quantified using Opal wearable sensors before and after the intervention period.
• A secondary analysis compared post-intervention leg movement rates in infants with DS to a control group of infants with typical development (TD).

Main Results:

• The kicking intervention led to a statistically significant increase in average leg movement rate among infants with DS (2253 to 2645 movements/hour).
• Post-intervention, infants with DS showed a significantly lower leg movement rate compared to infants with typical development (p=0.002).

Conclusions:

• Home-based kicking interventions can effectively enhance leg movement rates in infants with Down syndrome.
• Despite improvements, infants with DS continue to exhibit lower leg movement rates than their typically developing peers, highlighting the need for continued research and support.
