The Seated Postural & Reaching Control Test in Cerebral Palsy: A Validation Study.
Victor Santamaria, Jaya Rachwani, Geoffroy Saussez and 4 others
PMID 31900006WHAT IT FOUND
Trained raters scored the seated postural and reaching test consistently, and its scores lined up with other cerebral palsy measures.
The 5-second static sitting test detected only 31% of children with static control deficits.
Key findings
01Trained raters scored the SP&R-co with good or excellent reliability across dimensions, and repeated scoring by the same rater was excellent in 87% of dimensions.
02SP&R-co scores lined up with other cerebral palsy measures of gross motor function, hand use, and sitting control.
03Changing the static sitting test from a 5-second hold to a 20-second hold produced a significant difference in the proportion of trunk segments with deficits, and the 5-second test had 31% sensitivity.

What it does not show
The sample was small and recruited from CP camps, so the results may not apply to all children with cerebral palsy. Nineteen children were studied. Three were excluded from validity analyses, and 16 were used for construct and concurrent validity. Four children had GMFCS I-II although the test is more appropriate for GMFCS III-V, to allow full score range. Item-by-item inter-rater reliability was fair in 38% of items and poor in 3% of items. The study did not test responsiveness to change, and the authors plan to do this in a larger sample. Applicability to children younger than 7 years needs further study.
The easy way to misread this
Do not read these results as proof that using the test improves patient outcomes. The study validated scoring and relationships with other measures, but it did not test whether scores change over time.
