the crossing point of the armscye line and a line that bisects the anteroposterior diam-
eter of the upper part of the upper arm can be used (c.p. in Fig. 2.14D).

2.5.5.2 Armscye line

The armscye line is defined using a string or narrow tape or a neck chain. A string is
placed under the arm of the subject abducting his/her arm approximately 30°. The sub-
ject hangs down his/her arms naturally. Both ends of the string are brought up and
crossed over the acromion (Fig. 2.14D).

2.5.5.3 Armpit back fold point
The armpit back fold point is the highest point of the axilla (armpit) in the posterior
aspect of the trunk. The armpit back fold point is defined using a ruler and a tape mea-
sure. The subject abducts the arm approximately 30 degrees. Place the edge of the
ruler firmly into the axilla in a horizontal position and ask the subject to carefully
lower the arm to the side. Make sure that the ruler is level. Draw a short horizontal
line on the trunk at the top of the ruler on the posterior side (Fig. 2.15A). Remove
the ruler, and place a tape measure along the armscye line to extend the armscye line
below while the arm of the subject is hanging down naturally (Fig. 2.15B). The armpit
