Translatory motion testing

Rotoscoliosis motion testing evaluates the rotation of the vertebrae. Translatory motion testing evaluates side-bending motion. Lateral translation of the vertebra is coupled with side-bending in the opposite direction. Translatory motion of C4 toward the right is coupled with side-hend-ing of C4 to the left. For most cervical vertebrae, side-bending and rotation are coupled and occur...
