**7. Conclusions**

A full system to quantify the degree of facial palsy that will help to know the degree of muscle re–education improvement or not with the help of therapy was proposed and fabricated. By broadening the panorama of possible disease causes and keeping a timely record. An important point in performing the study with WaLi and WaL system is the placement of the mask, as the sensors are not located on the muscle to which they have been assigned, the result will be affected. By accentuating the degree of error of the system in the axis from which it was erroneously offset with respect to the point of interest.

For a face to be classified as healthy, it must have a high correlation, which means that the movement of both sides is very similar in intensity and time. According to the results provided by the system, healthy faces have a shorter response time between the largest relaxation point to the longest contraction that causes the difference between the mean of the signal and the data by increasing the standard deviation. So, it can be concluded that the greater the deviation, the correlation coefficient, and the arithmetic mean, the greater the symmetry of the face and the smaller the difference in reaction time.
