AIM: To investigate the validity and reliability of the revised Video-Observation
Aarts and Aarts module: Determine Developmental Disregard (VOAA-DDD-R). METHOD:
Upper-limb capacity and performance were assessed in children with unilateral
spastic cerebral palsy (CP) by measuring overall duration of affected upper-limb
use and the frequency of specific behaviours during a task in which bimanual
activity was demanded ('stringing beads') and stimulated ('decorating a muffin').
Developmental disregard was defined as the difference in duration of affected
upper-limb use between both tasks. Raters were two occupational and one physical
therapist who received 3 hours of training. Construct validity was determined by
comparing children with CP with typically developing children. Intrarater,
interrater, and test-retest reliability were determined using the intraclass
correlation coefficient. Standard errors of measurement and smallest detectable
differences were also calculated. RESULTS: Twenty-five children with CP (15
females, 10 males; mean age 4 y 9 mo [SD 1 y 7 mo], range 2 y 9 mo-8 y; Manual
Ability Classification System levels I-III) scored lower on capacity (p=0.052)
and performance (p<0.001), and higher on developmental disregard (p<0.001) than
46 age- and sex-matched typically developing children (23 males; mean age 5 y 3
mo [SD 1 y 5 mo], range 2 y 6 mo-8 y). The intraclass correlation coefficients
(0.79-1.00) indicated good reliability. Absolute agreement was high, standard
errors of measurement ranged from 4.5 to 6.8%, and smallest detectable
differences ranged from 12.5 to 19.0%. INTERPRETATION:
The VOAA-DDD-R can be
reliably and validly used by occupational and physical therapists to assess
upper-limb capacity, performance, and developmental disregard in children (2 y 6
mo-8 y) with CP.
