Myofascial continuity
Myofascial continuity refers to the anatomical connections through which connective tissue links a muscle to its neighbors and to other regions of the body, with no break between their sheaths.
Scientific basis
The sheaths of the muscles (epimysium, perimysium, endomysium), the septa and the aponeuroses extend into one another. These continuities make mechanical interactions between neighboring structures possible (Huijing, 2003).
A systematic review of dissection studies looked for the “myofascial chains” described in the literature: the anatomical evidence is strong for some of them, such as the chain that links the sole of the foot to the back of the skull by way of the back, and more limited for others (Wilke et al., 2016). Actual force transmission along these chains is documented mainly between nearby structures (Krause et al., 2016).
Continuity does not mean uniformity: geometry, attachments, fiber orientation and muscle activity determine whether a load stays localized or spreads. The progression is therefore as follows: an anatomical continuity makes a mechanical interaction possible, which becomes measurable transmission under certain conditions, generally attenuated with distance.
Blue Portance / SBNFA™ reading
The SBNFA™ reads myofascial continuity as a condition for coupling between regions, not as a pathway for unlimited propagation. An anatomical continuity does not automatically explain pain at a distance; it invites examination of the neighboring regions when one area loses its mobility.
Contribution to the analysis of sitting
When seated, the pelvis, thighs and lower back remain linked by connective-tissue continuities. The analysis observes whether the position lets these regions adjust together or locks part of them in place. It does not make it possible to attribute pain to a chain.
Not to be confused with
Myofascial chains, descriptive models that group several continuities over long distances; myofascial force transmission, the measurable transfer of force through these connections; fascial continuity, the extension of fascial layers into one another, without reference to muscles.
