The ability to determine the relationship between selective motor control
and upper extremity function in children with unilateral cerebral palsy (CP), and
to measure the functional outcome and efficacy of interventions designed to
improve selective motor control, has been limited by the lack of an objective,
validated tool. The primary objective of this study is to describe the
development of a clinical tool entitled Selective Control of the Upper Extremity
Scale (SCUES), and present evidence of its validity and reliability. METHOD:
Content validity was established through an expert panel (eight clinicians, mean
and median of 17y of clinical experience, range 2-30y). Intra- and interrater
reliability was determined by six occupational therapists who scored 10
participant studies. Construct validity of the SCUES was established by
comparison to the spontaneous functional analysis section of the Shriners
Hospitals Upper Extremity Evaluation, the Manual Ability Classification System,
and the Box and Block test for 25 children with unilateral CP. RESULTS: The
content validity ratio values were greater than 0 (indicating >50% agreement) for
33 of the 34 items (97%), and equal or greater than 0.5 (indicating >/=75%
agreement) for 26 of the 34 items (76%). Intrarater reliability was excellent
(intraclass correlation coefficient [ICC] >0.75) for all segments and joints of
the affected extremity. Interrater reliability was excellent for all segments and
joints of the affected extremity except the shoulder (ICC=0.72). The SCUES was
strongly correlated with the SHUEE (Spearman's rho=0.69, p=0.003). The SCUES was
not correlated with the Manual Ability Classification System (rho=-0.24, p=0.369)
or the Box and Block test (rho=0.47, p=0.066). INTERPRETATION: Psychometric
analysis of the SCUES revealed comparable validity to other accepted video-based
clinical assessment tools for the upper extremity in children with CP.
