In-Depth Information
Fig. 9.5 Deep to the long toe flexors are the complex attachments
of the tibialis posterior, also part of the DFL. (Reproduced with
kind permission from Grundy 1982.)
This line employs the last available compartment in
the lower leg (Fig. 9.8). The anterior compartment serves
the Superficial Front Line (Ch. 4), and the lateral pero-
neal compartment forms part of the Lateral Line (Ch. 5).
Just above the ankle, this deep posterior compartment
is completely covered by the superficial posterior com-
partment with the soleus and gastrocnemii of the
Superficial Back Line (Ch. 3) (Fig. 9.9). Access to this
compartment for manual and movement therapy is dis-
cussed below.
Fig. 9.6 The DFL passes between the SBL and SFL tracks,
contracting during the push-off phase of walking to support the
medial arch.
General manual therapy considerations
Piecemeal experimentation with the myofascia of the
Deep Front Line can produce mixed results. The myo-
fascial structures of the DFL accompany the extensions
of the viscera into the limbs - i.e. the neurovascular
bundles - and are thus studded with endangerment
sites and difficult points of entry. Practitioners familiar
with working these structures will be able to make con-
nections and apply their work in an integrated way. If
these DFL structures are new to you, it is recommended
that you absorb these methods from a class, where an
instructor can assure your placement, engagement, and
intent. With that in mind, we offer a palpation guide to
structures in the DFL, but not to particular techniques
in detail. References to the Anatomy Trains technique
DVDs, where techniques are presented visually, are pro-
vided when appropriate.
Common postural compensation patterns associated
with the DFL include chronic plantarflexion, high and
fallen arch patterns, pronation and supination, genu
valgus and varus, anterior pelvic tilt, pelvic floor insuf-
ficiency, lumbar malalignment, breathing restriction,
flexed or hyperextended cervicals, temporomandibular
Fig. 9.7 The three muscles of the deep posterior compartment of
the leg, deep to the soleus, comprise the DFL.
