6. Extremes of body shape. The long position is used to facilitate longitudinal and sagittal rotation. The wide position blocks those rotations and can be used when facilitating the transversal rotation.

10. Inhibition of movement. When a person uses peripheral fixed points, the trunk has difficulties to use its range of motion.

11. Transference and conclusion. Thinking of a movement creates a loss of balance through an altered muscular activation pattern. Water enlarges balance difficulties and forces a patient to react to these difficulties.
