Purpose: Obstacle crossing requires different spatial-temporal adaptations compared to normal walking. This research endeavor focused on exploring the spatiotemporal gait parameters and their variability during obstacle navigation in children with intellectual disabilities (ID) in comparison to their typical development (TD) counterparts.
Methods: This descriptive cross-sectional study included 16 girls with intellectual disabilities (ID) and 17 girls with typical development (TD) aged 8 to 13 years. Spatial-temporal characteristics and gait variability were assessed by motion analysis cameras and two force plates. A three-way ANOVA was used to analyze gait variables in normal walking and obstacle-crossing conditions.
Results: The analysis revealed no statistically significant distinctions in spatiotemporal gait parameters between the groups (P > 0.05). Obstacle crossing in both groups resulted in a decrease in double support time and a shortening of the stance phase in the trailing leg (P < 0.05). The variability in most spatial-temporal parameters was significantly higher in the ID group compared to the TD group (P < 0.05).
Conclusion: In light of the study's results, the similarity in most spatial-temporal gait parameters, along with increased step-to-step variability among individuals with intellectual disabilities relative to their typically developing counterparts, indicates an appropriate strategy for these individuals to adapt to environmental changes such as obstacle crossing. However, in the ID group, the trailing leg during obstacle crossing had lower speed and higher variability, indicating reduced motor control and adaptability of this leg, and consequently, an increased risk of obstacle collision.
