Seat inclinations affect the function of children with cerebral palsy: A review of the effect of different seat inclines

<i>Purpose</i>. 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. <i>Method</i>. 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. <i>Results</i>. 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. <i>Conclusions</i>. (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.
