Summary

The measurement of the facial deformation according to the body posture will be conducted by 3D scanning for each posture after marking the landmarks on the face. A 3D scan of the face will be conducted for 1 minute in a static state for the sitting posture to be used as a reference, the supine posture to gaze at the ceiling while lying down correctly, and the lateral posture to the side with the upper body facing left. Healthy volunteer and ALS with bulbar palsy participants will be asked to keep their mouths closed gently while the 3D scan was being processed. A post-processing of the 3D face scan data will be conducted to analyze facial deformation by the body postures. A facial deformation will be analyzed by measuring the amount of change in position for each reference point after aligning and rotating the facial data on the same basis. The relative ratio of the amount of position change to the size of the face will be analyzed. The present study will analyze the effect of the body posture on the position changes of the landmarks.
