Abstract

PURPOSE:

An evaluation of the current research evaluating the impact of seat inclinations upon postural control, muscle activity and upper extremity function in children with cerebral palsy.

METHOD:

A literature review searching 13 electronic databases was undertaken. Inclusion criteria were applied to abstracts found; full text research articles were retrieved and a critical review of the eligible articles completed.

RESULTS:

Ten studies were reviewed which investigated the effect of seat inclinations. Improved postural control and a reduction in pathological movements were achieved in anterior tilt; reduced postural sway was evident for children with spastic cerebral palsy sitting on anterior incline, and increased sway for those with hypotonia; extensor thrust was evoked when in posterior incline; and there was evidence of improved arm and hand function whilst seated in the functional sitting position as opposed a posterior seat incline.

CONCLUSIONS:

(i) The current literature is inconclusive, however there are indications that neutral and anterior seat inclines do positively affect function for children with cerebral palsy; (ii) Individual assessment of seating ability and need is advocated for these children rather than the adoption of a universal seat incline.
