Abstract
PurposeThe purpose of this study was to develop a reliable and valid instrument, named the Observatory Test of Capacity, Performance, and Developmental Disregard (OTCPDD), for measuring the amount and quality of use of affected upper limb functions in the daily routines of children with CP.MethodsForty-eight participants (24 children with CP and 24 matched typically developing children) were recruited. The OTCPDD was administered twice (the spontaneous use condition first, followed by the forced use condition) on children with CP. Their parents were asked to complete the Pediatric Motor Activity Log-Revised (PMAL-R). The internal consistency, the intrarater and interrater reliabilities, and the convergent and discriminate validities were measured.ResultsThe internal consistency (Cronbach’s alpha) and the intrarater and interrater reliabilities were higher than 0.9 for all of the OTCPDD scores. The convergent validity was confirmed by significant correlations between the OTCPDD and the PMAL-R. For the discriminant validity, significant differences (p<0.05) were found between children with CP and typically developing children.ConclusionsThe results support that the OTCPDD is a reliable and valid observation-based assessment. The OTCPDD, which uses bimanual daily living activities, is able to represent the children’s general affected hand functions (including capacity, performance, and developmental disregard) in their daily routines.
Highlights
Cerebral palsy (CP), defined broadly as “a non-progressive motor impairment syndrome caused by a problem in the developing brain,” is the most common pediatric physical disability, with an incidence of 2.11 per 1,000 live births [1]
The convergent validity was confirmed by significant correlations between the OTCPDD and the Pediatric Motor Activity Log-Revised (PMAL-R)
The results support that the OTCPDD is a reliable and valid observation-based assessment

The OTCPDD was administered twice (the spontaneous use condition first, followed by the forced use condition) on children with CP. Their parents were asked to complete the Pediatric Motor Activity Log-Revised (PMAL-R). The internal consistency, the intrarater and interrater reliabilities, and the convergent and discriminate validities were measured
