An integrative Blue Portance concept referring to the body’s capacity to adjust its postural organization and its tissue responses to stress, while preserving balance, mobility and load distribution.
3 references cited Scope and limits in the entry
The possibilities available to a person in a given situation to change their postural organization and vary the stresses placed on tissues, without losing balance or concentrating those stresses over long periods.

In the SBNFA™, adaptive reserve refers to the functional margin still available that allows a biological system to change its organization when a load or a situation changes.

Alcock’s canal, or the pudendal canal, is a fascial passage on the lateral wall of the pelvis through which part of the pudendal nerve runs together with the internal pudendal vessels.

Algophobia is an intense, persistent or disproportionate fear of pain itself. It differs from the ordinary fear of getting hurt and from kinesiophobia, which concerns movement.

Allodynia is pain caused by a stimulus that is normally not painful: a light touch, the contact of clothing, gentle pressure. It is a descriptive clinical term: it describes what the person feels, without by itself designating a mechanism.

Anterior pelvic tilt refers to a forward tilt of the pelvis, which increases sacral slope and is usually accompanied by a deepening of the lumbar curve. It is an orientation or a movement, not a disorder.

The base of support is the area bounded by the outline of the body's points of contact with the ground or a supporting surface. Static balance requires the projection of the center of mass to remain within this area.

Biotensegrity is a model that applies the principle of tensegrity to living organisms: elements that resist compression, such as bones, are held in place by a continuous network of tissues under tension, such as muscles, ligaments and fascia.

The body schema is a sensorimotor representation of the body, largely nonconscious and continuously updated, that makes it possible to locate body segments and organize posture and movement. It is one of the dimensions of body representation.

The center of mass is the point at which the total mass of the body can be considered to be concentrated. It moves with every change of position; in the Earth's gravitational field, it coincides in practice with the center of gravity.

Central sensitization refers to an amplification of the central nervous system's response to sensory signals: pain can then be more intense, more widespread or longer-lasting than the state of the tissues would suggest.

Pain is called chronic when it persists or recurs for more than three months. It may accompany an identified disease or be a condition in its own right.

Cluneal neuralgia is pain linked to irritation of the cluneal nerves, small sensory nerves of the skin of the buttock. Depending on the branch involved, it is felt in the upper buttock and lower back, or in the lower buttock, sometimes markedly when sitting.

Pain located in the tailbone (coccyx) region, often worse when sitting.

In SBNFA™, the cone of balance refers to the functional space within which the body can move its center of mass, stop, remain stable and then move again, and respond to a perturbation without losing control of its posture.
2 references cited Scope and limits in the entry
Continuous adjustments of balance, muscle tone and load distribution during a posture or a movement.

Endometriosis is a chronic inflammatory disease in which tissue similar to the lining of the uterus grows outside the uterine cavity. It can cause severe pelvic pain and infertility.

The endopelvic fascia is the connective tissue of the deep pelvis, located between the peritoneum and the pelvic floor muscles. It lines the walls of the pelvis and surrounds the pelvic organs, which it helps to support.

The extracellular matrix is the network that surrounds the cells of a tissue. In fascia, it combines fibers, mainly collagen, with a highly hydrated ground substance, and gives the tissue its mechanical properties.

Fascia are connective tissue structures that envelop, connect or separate certain parts of the body. The "fascial system" refers to a broader set of connective tissues considered in their functional continuity.

A fascial adhesion is an abnormal union, through fibrous tissue, between two surfaces that normally move relative to each other, such as two layers of fascia, or a fascia and a muscle, an organ or a nerve. The term should not be used to describe any stiffness, pain or sensation of “stuck fascia.”

Fascial densification is a research hypothesis: the loose connective tissue located between the layers of fascia would become more viscous and hinder their gliding, without any accumulation of collagen.
2 references cited Scope and limits in the entry
Fascial fibrosis refers to a pathological, persistent accumulation of fibrous matrix, mainly collagen, in a fascia, generally associated with an injury, prolonged inflammation or a fibrotic disease.
