Early Walkers- Understanding Gait Parameters To Improve Pediatric PT Interventions

PURPOSE: Independent ambulation is crucial for children's function and participation. Limited research exists on physical therapy (PT) interventions for promoting independent walking in children with motor impairments. Understanding comparative gait parameters in typically and atypically developing children is crucial for PT interventions. This research pilot aimed to establish a collection of data to compare gait parameters in children typically and atypically developing. METHODS: IRB approval obtained, recruitment through emails, flyers, and social media. Inclusion criteria: age under 8 years, independent walking or cruising ≤6 months with/without assistive device. Demographic and developmental data collected via survey. Participants walked on instrumented walkway gait-analysis system, with caregiver encouragement. Data was processed through the walkway system for gait analysis. RESULTS: 4 participants (3 males, 1 female), average age 19 ± 7 months, 1 with medical diagnosis (Subj. 19), all walked without assistive device. Subj. 19 exhibited a longer stance phase and slower cadence, consistent with previous research demonstrating differences in stride length, stance time, cadence, and gait velocity between children who are typically and atypically developing. The average stride width did not differ between the populations, suggesting all early walkers need a wide base of support for gait stability. Subj. 19 developed sitting and walking later than the typically developing participants. Research suggests the timing of independent sitting may predict gait acquisition. CONCLUSIONS: Research with a large sample size is needed to guide future PT interventions to promote independent walking. Data from this pilot study found differences in gait parameters between children who are typically and atypically developing. - Gait Parameter Typically Developing(n = 3) Atypically Developing(n = 1) Swing % 40 (±5.8) 7 Stance % 60 (±5.7) 93 Cadence (steps/min) 151.6 (±44.9) 30.2 Stride Width (meters) 0.1 (±0.05) 0.2
