Based on the number of problems that develop during childhood, it is clear that scoliosis has an important place because of its impact and in early adulthood. The main objective of the study was to evaluate the relationship between sex, scoliosis and handedness. The sample consisted of 2822 participants, aged between 8 and 12 years, from the province of Almería. Two instruments were used to measure, Inventary Laterality of Edinburgh and Test de Adams, to analyze the selected variables. No statistically significant differences were found between the variables laterality and sex (p= 0.106) or between laterality and scoliosis (p= 0.673); significant differences however, were found between scoliosis and sex (p<0.001). Principal conclusions are the importance in the development of appropriate intervention programs bearing in mind the number of children with scoliosis, especially in girls.
