While the outer part of the foot (base of little toe to heel) is always shorter than the inner aspect (from base of big toe to heel), there is a common balanced proportion. If your hands are not up to the task, consider using the ‘ball under the foot’ technique described below in ‘A simple test’.Ĭompare the inner and outer aspect of your client’s foot. Although structural work with the plantar surface often involves a lot of knuckles and fairly hefty stretching of this dense fascia, any method that aids in releasing it will communicate to the tissues above (DVD ref: Superficial Back Line, 10:57–16:34). Limitation here often correlates with tight hamstrings, lumbar lordosis, and resistant hyperextension in the upper cervicals. The plantar surface of the foot is often a source of trouble that communicates up through the rest of the line. The SBL is a cardinal line primarily mediating posture and movement in the sagittal plane, either limiting forward movement (flexion) or, when it malfunctions, exaggerating or maintaining excessive backward movement (extension).Īlthough we speak of the SBL in the singular, there are, of course, two SBLs, one on the right and one on the left, and imbalances between the two SBLs should be observed and corrected along with addressing bilateral patterns of restriction in this line.Ĭommon postural compensation patterns associated with the SBL include: ankle dorsiflexion limitation, knee hyperextension, hamstring shortness (substitution for inadequate deep lateral rotators), anterior pelvic shift, sacral nutation, lordosis, extensor widening in thoracic flexion, suboccipital limitation leading to upper cervical hyperextension, anterior shift or rotation of the occiput on the atlas, and eye–spine movement disconnection. The most general statement that can be made about any of these Anatomy Trains lines is that strain, tension (good and bad), trauma, and movement tend to be passed through the structure along these fascial lines of transmission.
