A, Functional assessments using the Movement Assessment Battery for Children (MABC) in child and adolescent CCS exposed to neurotoxic chemotherapy compared with population reference ranges. Functional deficit is seen in 2 of 3 manual dexterity tasks and 1 of 3 balance tasks and is represented as the number of standard deviations below the population mean. The dotted line indicates the population mean and the error bars, SEM. B-D, Functional assessments in adult CCS exposed to neurotoxic chemotherapy compared with laboratory controls. B, Fingertip sensory threshold for light touch using Von Frey monofilaments (increased threshold in CCS, 0.1 mN; 95% CI, 0.03-0.2; P = .01). C, Fingertip cutaneous resolution threshold using the grating orientation task (increased threshold in CCS, 0.7 mm; 95% CI, 0.1-1.2; P = .003). D, Manual dexterity using the grooved peg board task (increased time to completion in CCS, 5.9 s; 95% CI, 1.6-10.1; P = .008). The black bar indicates the median and the error bars, interquartile ranges.
