2.5.4.2 Front neck point

The front neck point is the crossing point of the median line and a line tangent to the
highest points of the medial (or sternal) extremities of the right and left claviculae.

2.5.4.3 Side neck point and neck base line
The side neck point is the crossing point of the neck base line and the anterior border of
the trapezius muscle. The neck base line is defined using a neck chain (Fig. 2.13A).
The neck chain is placed around the neck so that it passes the back neck point and the
front neck point. The anterior border of the trapezius muscle can be easier to palpate
by asking the subject to place his/her hand on his/her opposite shoulder. Find the ante-
rior border of the trapezius muscle, and draw a line along the anterior border with the
subject hanging both arms naturally downward (Fig. 2.13B). Draw a line along the
neck chain to make a cross at the side neck point.

2.5.5.1 Acromion, shoulder point, and shoulder line
ISO TC 133/WG 1 decided to use acromion as the shoulder point in ISO 8559-1:2017.
The acromion is the most lateral point of the lateral edge of the acromial process of the
scapula (Fig. 2.14A, point a). The measurer stands at the back of the subject and pal-
pates the lateral borders of the right and left acromial processes with the balls of the
index fingers (Fig. 2.14B). By moving the ball of the index finger in the mediolateral
direction, locate the edge between the superior and lateral aspects of the acromial pro-
cess. Draw a line along the edge. Draw a short line perpendicular to this line at the
most lateral point of the lateral edge (Fig. 2.14C, point a). (See also Section 2.4.1.)
The shoulder point is used to define the shoulder line, a line connecting the shoul-
der point and side neck point. Usually, acromion is located posterior to the ridgeline of
the shoulder, and this may not be desirable for defining the shoulder line. In this case
