Mean values ± standard deviation (SD). n, number of participants; UCP, unilateral cerebral palsy adolescents; TD, typically developing adolescents; COM, center of mass; P-value, P value for interaction [condition (overground vs. treadmill) x group (UCP vs. TD)] of the 2-way repeated-measures mixed design ANOVA.
*
For significant condition (overground vs. treadmill) effect;
