Abstract
The aims of this study were to describe the sagittal integral morphotype (SIM) of classical
ballet (CB) dancers, and to establish predictor factors and their cut off values for high risk of
experiencing sciatica or low back pain (LBP). This retrospective cohort study was performed in
33 female professional CB dancers. Data related to anthropometric parameters, CB dance experience,
sciatica or LBP history, and sagittal spine curvatures were collected. A binary logistic regression
and receiver-operating characteristic analysis were performed. The main spine misalignments
observed in the SIM of CB dancers were thoracic functional hyperkyphosis, hypomobile kyphosis,
and hypokyphosis, and those for the lumbar curvature were hyperlordotic attitude and functional
hyperkyphosis. The lumbar curvature in slump sitting and trunk forward bending positions, together
with the stature, were significant predictor factors of sciatica history, while the years of dance
experience was a significant predictor factor of LBP history. The cut off values analysis revealed that
dancers with a stature of 161 cm or less, and those with 14 years of experience or more, have a greater
probability of experiencing sciatica or LBP history, respectively.
