The current SR is intended to provide an updated critical synthesis of the seating literature beyond the literature
reviewed in the 1995 and 2005 reviews.Furthermore,
the present SR benefits from having had the studies reviewed and rated by multiple reviewers and, unlike the
Stavness review,13 includes a variety of different outcomes,
including upper limb function. Consequently, our SR addressed 2 focused questions:
(1) What is the effect of adaptive seating on sitting posture or postural control in
nonambulatory children from birth to 20 years of age, with
varying types and severity of CP?
(2) What are the effects of
resultant changes in sitting posture or postural control on
other aspects of functioning within the ICF model?
