The movement direction first mentioned in the variable is valued as being positive; for example, head extension is valued as positive.

Table 1: Mean and standard deviation of dependent variables of postural alignment 300 ms before the preferred hand started to reach. df = 1, \(p\) = 0.416 and \(p\) = 0.882, respectively). Children with CP aligned the lateral ankle in a pronation and adduction (positioned foot inward) position, whereas TD children aligned the lateral ankle in a supination and abduction (positioned foot outward) positions (Table 1). Children with CP aligned the medial ankle in a rather neutral position, whereas TD children aligned the medial ankle in a pronation and abduction position. Neither task nor interaction effect was seen.
