Table 1.
Characteristics of children with cerebral palsy (CP) and typically developing children (Con).
Fig 1.
Percentage of children able to complete at least one unassisted repetition at each step height of the lateral step-up test (LSUT).
Ring charts demonstrate the percentage of children with cerebral palsy (CP) and typically developing control children (Con) who were able to complete one or more repetitions at 10 cm, 15 cm, and 20 cm step heights of the LSUT.
Fig 2.
Group differences in lateral step-up test performance (LSUT).
Bar graphs demonstrate group differences in: A) number of repetitions completed at the 10 cm, 15 cm, and 20 cm step heights of the LSUT, and B) the composite score of LSUT performance in children with cerebral palsy (CP) and typically developing control children (Con). Values are means ± SE. *Different from controls, p < 0.05.
Fig 3.
Test-retest reliability and agreement in lateral step-up test (LSUT) performance.
Scatter plots (A-D) and Bland-Altman plots (E-H) demonstrate the test-retest reliability and agreement, respectively, of repetitions completed at each step height of a LSUT at 10 cm, 15 cm, and 20 cm and the LSUT composite score in children with cerebral palsy (CP).

Inter-day, test-retest lateral-step-up test (LSUT) repetitions at different step heights and composite score in children with cerebral palsy (n = 20).
Fig 4.
Group differences in physical activity.
Bar graphs demonstrate group differences in A) ankle and B) hip physical activity counts in children with cerebral palsy (CP) and typically developing control children (Con). Values are means ± SE. *Different from controls, p < 0.05.
Fig 5.
Relationship between performance on the lateral step-up test (LSUT) and physical activity.
Scatter plots demonstrate the relationship between (A-D) ankle and (E-H) hip physical activity counts and repetitions completed at 10 cm, 15 cm, and 20 cm step heights of the LSUT and the LSUT composite score in children with cerebral palsy (CP) and typically developing control children (Con).
