The Effect of Visual Environmental Distraction on Gait Performance in Children

Area of Science:

• Pediatric Gait Analysis
• Developmental Motor Control
• Visual Attention and Motor Performance

Background:

• Gait development in children is a complex process influenced by various factors.
• Understanding how environmental stimuli affect gait is crucial for pediatric motor development research.
• Walking experience (WE) may modulate the impact of external factors on gait stability.

Purpose of the Study:

• To investigate the effect of visual distraction on gait parameters in children.
• To determine the role of walking experience (WE) in mitigating the effects of visual distraction on gait.
• To provide insights for physical therapists in gait assessment and intervention.

Main Methods:

• Forty-two typically developing children were categorized into three groups based on walking experience (early, preschool, experienced).
• Gait parameters including velocity, step length, step width, and double limb support percentage (DLS%) were measured under conditions of no visual distraction and with visual distraction.
• Multivariate analysis of variance was employed to analyze differences in gait parameters.

Main Results:

• Visual distraction significantly affected gait performance across all children, irrespective of their walking experience.
• Gait velocity decreased significantly (from 110.04 to 97.73 cm/sec) under visual distraction.
• Double limb support percentage (DLS%) increased significantly (from 18.29% to 20.39%) during visual distraction, indicating reduced stability.

Conclusions:

• Visual distraction poses a challenge to gait stability and performance in children.
• Physical therapists must consider attentional demands when assessing children's gait.
• Interventions may need to directly address attention as a limiting factor in motor learning and performance.
