AIM: To investigate the test-retest reproducibility of the Muscle Power Sprint
Test (MPST), the 10 x 5-m sprint test, and the arm-cranking Wingate Anaerobic
Test (WAnT) in children and adolescents with cerebral palsy (CP). A secondary
objective was to assess the construct validity of the MPST. METHOD: Twenty-three
participants with spastic CP (mean age 13 y 3 mo, range 7-18 y, SD 3.6 y; 18
males, five females, two classified as having spastic unilateral CP, 21 as having
spastic bilateral CP) using a manual wheelchair for at least part of the day were
recruited and tested in different rehabilitation settings in the Netherlands.
Participants were classified as in Gross Motor Function Classification System
Expanded and Revised (GMFCS-E&R) levels III and IV. RESULTS: Intraclass
correlation coefficients (range 0.93-0.99; 95% confidence interval 0.82-1.0) for
all variables indicated highly acceptable reproducibility. Limits of agreement
analysis revealed satisfactory levels of agreement. The MPST variables
demonstrated very strong significant positive correlations for peak power and
mean power from both tests (peak power: r=0.91, p<0.001; mean power: r=0.88,
p<0.001). INTERPRETATION: The MPST, the 10 x 5-m sprint test, and the
arm-cranking WAnT are reproducible tests for measuring anaerobic performance and
agility in adolescents with spastic CP who self-propel a manual wheelchair. The
MPST has been shown to be a valid test to measure anaerobic performance in this
population.
