inverted. In other words, the distance between the
outside of the foot and the iliac crest is maximized.
In general, inversion and dorsiflexion of the foot
done at the same time will stretch the peroneals,
while eversion and plantarflexion is created by their
• An interesting stretch for the ITT-abductor portion
of the line is to stand with one foot placed in front
of and outside the other. Do a forward bend, and
the ITT of the posterior leg will be stretched.
• The lateral portion of the trunk and neck may be
stretched through a variety of common stretches,
such as Parighasana or the Gate pose in yoga.
In movement terms, the lateral flexion movement
through the spine is a primary foundation stone for
walking. Lying prone on the floor and developing an
even eel-like 'wiggle' contributes to integration through
this line. In a therapeutic setting, the practitioner can
observe this side-to-side movement and either use it as
an assessment for where to work, or use a hand to bring
the client's attention to where movement is not
Fig. 5.16 Two deeper concomitants of the Lateral Line, although
both structures are technically part of the Deep Front Line, are the
scalenes and the quadratus lumborum, which suspend the rib
cage between them.
The quadratus lumborum (QL) is part of a layer deep to the
transversus abdominis and thus not fascially connected to the
superficial abdominal muscles of the LL. We cannot, however,
ignore its congenial relationship with the LL. Running essen-
tially from the iliac crest up to the 12th rib, it is the real para-
spinal muscle in the lumbars. The erectors (SBL), though they
(iliocostalis especially) can be involved in lateral flexion, are
more often employed to create extension and hyperextension.
The rectus abdominis (SFL) creates primarily trunk flexion. The
psoas (the medial portion of the Deep Front Line in this area,
see Ch. 9) can create a complex of moves, including flexion,
hyperextension, lateral flexion, and rotation in the lumbars.
The QL, however, is uniquely placed to mediate a fairly pure
lateral flexion. Therefore any work with the LL should also
include some attention to the tone and fascia of the QL, even
though it is not, by Anatomy Trains rules, directly part of the
The Deep Lateral Line
There are two sets of myofascia that need to be considered
for a complete view of the lateral line, even though they clearly
belong to (and will be further discussed with) the Deep Front
Line (Ch. 9). Together, these two muscle sets - actually lateral
elements of the Deep Front Line - comprise a 'Deep Lateral
Line', which is included here because working with these
structures will frequently improve your results with LL issues,
including breathing and bilateral asymmetries. (DVD ref:
Lateral Line 52:57-58 .10)
At the other end of the rib cage, we have a deep layer in
the neck, the scalenes and associated fascia. The scalenes
form a kind of skirt around the cervical vertebrae, acting to
create or stabilize lateral flexion of the head and neck, in a
similar fashion to the QL. We can imagine the rib cage (and
indeed the lungs) as being suspended between the QL pulling
from one end and the scalenes pulling from the other (Fig.
