Left-handedness and inverted handwriting postures are more frequent among birth-stressed individuals. Because twinning is also associated with increased birth risk, 298 twins were compared to 1192 age and sex matched singletons. Both left-handedness and inversion were significantly more common in twins, although other indexes of laterality were not affected.
