The influence of determining factors on sit-to-stand (STS) movement in adults has been extensively described in the literature; however, there is a lack of information about such factors on children. Therefore, the purposes of the present study are to analyze the scientific publications about intrinsic and extrinsic factors influencing STS movement in children and to describe methodological procedures used in the studies under review. A bibliographical review was obtained from relevant database (1988-2009) using keywords, such as rising, chair, sit-to-stand, and children. In all, 109 articles were identified and 11 were selected. The literature indicates there is a lack of articles investigating disabilities other than cerebral palsy as well as extrinsic factors such as chair-type characteristics in typical and atypical children.

In 9-month-old-infants adjustments in the reaching pattern to sudden changes in object location were examined. An attractive ball was presented to the infants at their midline and on some trials (perturbation trials) the ball suddenly changed position 15 cm to the right or left during the reach. For the perturbed trials the movement times approximately doubled compared to the control trials and significantly fewer balls were grasped. The results indicate that infants need to finish the first movement before being able to redirect the reach to a new destination. The correlation between the latency of the head and hand adjustment to the perturbation were 0.85 and 0.78 for movements to the left and to the right, respectively, indicating a tight coupling. The time between the start of the perturbation and peak velocity (TPPV) was significantly shorter for the head movement than for the hand movement, indicating that the head is leading the hand.
