Rjg. Vandenbergemons et al., RELIABILITY OF TESTS TO DETERMINE PEAK AEROBIC POWER, ANAEROBIC POWERAND ISOKINETIC MUSCLE STRENGTH IN CHILDREN WITH SPASTIC CEREBRAL-PALSY, Developmental Medicine and Child Neurology, 38(12), 1996, pp. 1117-1125
Test-retest reliability of measurements of peak aerobic power (cycle e
rgometer), anaerobic power (cycle ergometer), and isokinetic muscle st
rength of the knee (Cybex) was established in 12 young children with c
erebral palsy (spastic diplegia/tetraplegia; mean age 8.8 years) and i
n addition in 39 healthy controls (mean age 9.2 years). The cycle ergo
meter tests were found to be reliable in both the group with CP and th
e control group (test-retest correlations varying from 0.72 to 0.96).
The isokinetic strength test in the group with CP was only reliable at
30 degrees/s, whereas in the control group high test-retest correlati
ons were also found at 600 degrees/s and 1200 degrees/s.
