on the biggest posterior projection point
(Fig. 2).
Midstylion-Dactylion Lenght (MDL) – Hand
Length: The child assumes a relaxed standing
position with the left arm hanging by the side.
The right elbow must be slightly flexed, forearm
supinated and the fingers extended (but not in
hyper-extension). The measure is taken in
parallel with the hand´s longitudinal axis
between midstylion point (medial point of an
imaginary horizontal line localized on the anterior
area of the wrist at the level of the stylion,
which means the most distal point of the lateral
margin of the styloid process of the radius)
and the dactylion point (the tip of the middle
finger) (Fig. 2).
Acromiale-Dactylion Lenght (ADL) - Upper
Extremity Length: The child assumes a relaxed
standing position, with the arms hanging by the
sides having the hand with its fingers together.
One branch of the calliper is held on the
acromiale point (the most superior aspect of the
most lateral part of the acromion border), while
the other branch is placed on the dactylion point
(Fig. 2).
Trochanterion Height (TH) - Lower Extremity
Length: The child assumes a standing position
with his left upper limb along the trunk and the
right upper limb flexed over the chest, with the
feet together and the weight equally distributed
on both feet. The measure is taken from the most
superior trochanterion point to the floor (Fig. 2).
Maximum Vertical Reaching Height (MVRH) -
The child assumes a standing position, barefooted
facing the anthropometer as close as
possible. The child must raise his dominant
upper limb extended with his hand opened with
the fingers together, pushing up, as far as
possible, without raising the heels from the floor
(Fig. 2).
Handgrip: The child assumes a standing position
and takes the dynamometer in the preferred
hand. He must squeeze it forcefully (gradually
and continuously), at least 2 seconds, holding
the dynamometer away from the body. During
the test, the arm and hand holding the
dynamometer should not touch the body. The
instrument is held in line with the forearm and
hangs down at the side. The child repeats the
test with the non preferred hand (Fig. 2).
The measurement instruments used were a
scale – Seca model 761 7019009 from Vogel &
Halke (Germany), to determine body mass; an
anthropometer from Siber-Hegner GPM (Zurich)
to obtain stature and trochanterion height, a
large sliding caliper from Siber-Hegner GPM
(Zurich) to take lengths (acromiale-dactylion and
hand) and breadths (biparietal and A-P chest),
an anthropometric tape from Rosscraft to measure
the head circumference and a grip strength
