Predictors of standardized walking obstacle course outcome measures in children with and without developmental disabilities

Purpose: This study was designed to determine which characteristics of children predict measures on the Standardized Walking Obstacle Course (SWOC). Methods: SWOC testing was performed under 3 conditions: (1) walk, (2) walk with a tray, and (3) walk wearing shaded glasses. Trials consisted of standing up, walking the course in 1 direction, and sitting down. Children (n = 440) completed 2 trials per condition. Trial measures included time, and numbers of steps, stumbles, and steps off the path. Relationships were evaluated using Chi-square analyses and significant predictors were determined by multiple logistic regression analyses. Sensitivity and specificity were calculated to determine the accuracy of disability as a predictor. Results: Age, weight, and disability were the strongest predictors (P \u3c .05). Increased age and weight predicted shorter time and fewest steps. Disability predicts longer time and most steps. Conclusion: The SWOC is appropriate to screen children for disabilities in functional ambulation. Copyright © 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins
