“…We have introduced for the very first time a method that estimates both predominant types of asymmetry (DA and FA) in each individual with AIS. The method is based upon the subtraction of the mean shape asymmetry of the sample from the TAS of each patient (Klingenberg & Polak, 2003;Kordsmeyer et al, 2020;Rott et al, 2003). This means that the average asymmetry could, clearly, influence the results (Goldberg et al, 1997a).…”

“…The 'side' effect defines the significant presence of DA in the sample subjected to study if p < 0.05, while the interaction between 'individuals' and 'side' defines the significant presence of FA in the sample if p < 0.05. The DA effect in our sample corresponds to the mean DA of shape (Klingenberg, 2003a(Klingenberg, , 2003bKordsmeyer et al, 2020).…”

Fluctuating asymmetry (FA) is a phenomenon present in adolescent idiopathic scoliosis (AIS; Dangerfield et al., 1997;Goldberg et al., 1995Goldberg et al., , 1997b, which includes all random deviations between the left and the right sides of the human torso. It has been described in the literature as an expression of developmental instability and a consequence of environmental and/or genetic factors (Klingenberg, 2003a(Klingenberg, , 2003bValen, 1962). Hypothetically, the left and the right sides of the torso share the same genome, and as far as development is considered to be regulated by genetics, a perfectly symmetrical phenotype should be expected in the frontal plane. In the practice, the FA comprises the random deviations from the mean asymmetry of the shape in the sample subjected to study, a type of asymmetry that has been termed 'directional asymmetry (DA)' (Klingenberg, 2003a(Klingenberg, , 2003b. Nevertheless, the exposition to non-genetic factors like nutrition, gravity or lifestyle could modify the way an organism grows by perturbating its developmental system (Klingenberg, 2003a(Klingenberg, , 2003b. These environmental factors may cause the asymmetries in the human torso
