inward, toward the other, as she brings them forward, the
entire lower SPL sling may be tight on that side.
When we note how the SPL runs from the ASIS in the front
of the pelvis to the outside of the knee and then down to the
inside of the ankle, we can clearly see how tightening it can
affect knee direction, by pulling the outside of the knee
toward a line running straight from the ASIS to the medial
ankle (Fig. 6.28). Loosening this line from above or below
prior to local soft-tissue work, or prior to assigning remedial
exercise to restore proper knee tracking, will greatly increase
the efficacy of the treatment (DVD ref: Spiral Line,

The 'heel foot' and the sacroiliac joint
It has long been noted that the bones of the foot divide fairly
neatly down a longitudinal axis into the bones that comprise
the medial arch and those that comprise the lateral arch (Fig.
Borrowing terms from dance, these could be referred to as
the 'heel foot' and the 'toe foot'. The 'toe foot' is clearly
designed to take the primary weight: if you stand and let your
weight swing onto your toes, you will feel the pressure in the
first three metatarsal heads on up to the talus. Seeing how the
talus lines up with the main weight-bearing bone of the shin,
the tibia, only reinforces our conviction. Swinging forward and
keeping your weight on the two outside toes, unless you are
quite accustomed to it, is quite difficult to do, and nearly
impossible to maintain.
The heel, of course, does take weight in standing and
walking, but the outer two toes and the associated bones (4th
and 5th metatarsals and the cuboid) are really designed more
as balancers, outriggers for the foot's canoe (Fig. 6.30)
Fig. 6.26 Shortness in part of the lower SPL can create the
complementary patterns to those in Figure 6.23
Fig. 6.28 Because the Spiral
Line passes from the front of the
hip to the outside of the knee to
the inside of the ankle,
tightening this line can tend to
induce medial rotation at the
Fig. 6.27 In assessing knee tracking, let both knees come straight
forward with the pelvis tucked under and the heels on the ground,
and watch the 'headlight' of the knee to see whether it tracks at
all to the inside or outside as it comes forward or back.
