ALPHA: slope of the lumbar spine; BETA: slope of the thoracic-lumbar spine; GAMMA: slope of the upper thoracic spine; KPT: angle of body inclination; KKP: angle of thoracic kyphosis; GKP: depth of thoracic kyphosis; KLL: angle of lumbar lordosis; GLL: depth of lumbar lordosis; KNT: the angle of trunk declination, determining the vertical decline of the C7-S1 line in the frontal plane; KLB: angle of the shoulder line; UL: the difference in the height of the inferior angles of the scapulas in the coronal plane; UB: the difference in the depth of the inferior angles of the scapulas; OL: the difference in distance of the inferior angles of the scapulas from the spine; UK: the maximum deviation of the line of the spinous processes from the C1–S1 line on the -axis; (mm): millimeter; (°): degree.
