Following the current trend of evaluating results and showing them objectively, Vila-Rovira Institute has recently added to its protocol of breast surgery a previous examination, called Bouncing Objective Test (BOT), that allows quantify parameters of motion to assess the strength of the natural breast.

In the United States after a survey of 225 women who had undergone a breast augmentation during 2012, 75% of those surveyed women, rated the firmness of their breast as “the just”.

The valuation of the firm so far was subjective, despite the influence of the breast movement.

An extreme strength, to become the breast too “rigid” and its movement would not be natural.

The BOT test allows reproducing with a major accuracy the natural rocking motion of the breast, maintaining intact its firmness.

Once parametrized the natural movement of the patient in 3 movements: lateral (lateral movement), vertical (top to bottom) and rotatory inside-out, besides knowing structurally the area to intervene, the selection process of the prostheses of the patient and the process of implant, guarantees of success will grow stronger.


The movement is analyzed thanks to a scanned system of analysis in three dimensions in which, with the help of 3 markers, one fixed on the sternum and two mobile located in the nipples, and after a bending on the truck along its longitudinal axis in standing position, it captures the natural movement of the breast.

Once the images are captured, are analyzed the trajectory, displacement, speed and acceleration of the moving markers respect with the fixed marker.


This gives a numerical degree of the relative movement (the average of the movement in each breast from the same point said) that provides guidance in the preparation of the intervention and during this one.
