Due to trauma or inflammation fascia may shorten and what was previously a pain free range of motion may become painful and restricted. (Langevin 2008)
“Fascia forms a gliding interface with underlying muscle [allowing] free excursion of the muscle under the relatively immobile skin. A plane of potential movement exists in the form of the areolar tissue layer, [apparently] lined with a lubricant, hyaluronic acid.”
Binding may occur among layers, that should stretch and glide on each other, potentially impairing motor function. (Fourie 2012).
Many therapeutic manual approaches claim to relieve such dysfunctional states, with some hypothesised explanations.
“In order to achieve a viscoelastic deformation during manual intervention, without causing tissue damage, … there should be no slow increase in the applied force. Rather it is recommended that a fairly constant force be maintained, for up to 60 seconds, in order to allow for a plastic stress relaxation response of the tissue.” (Chaudhry et al 2008).
· Schleip (In Press) suggests some responses may relate to a sponge-like squeezing and refilling in the semi-liquid ground substance.
· Loose connective tissue
and light tissue stretch “may be key to the therapeutic mechanismof treatments using mechanical stimulationof [loose] connective tissue” (Langevin 2005) e.g myofascial release (Pilat 2009)
· Collagen architecture responds to loading (Kjaer et al 2009). Load can be used therapeutically to stimulate tissue repair and remodelling in tendon, muscle, cartilage and bone.
Exercise and manual methods stimulate tissue repair and remodelling in tendon, muscle, cartilage and bone.
Mechano-coupling = Physical load (often
shear or compression) that perturbs cells, transforming into various chemical signals – within and among cells.
Cell–cell communication = Stimulus in one location leads to a distant cell registering a new signal, despite distant cell receiving no mechanical stimulus.
Effector cell response = Mechanical loading stimulates protein synthesis at the cellular level, promoting tissue repair and remodelling (Kahn & Scott 2009)
· Trigger point release may involve repetition of voluntary isometric contractions that initiate lengthening of the series elastic (fascial) component of sarcomeres. (Simons 2002).
· Active scars restrict movement and produce pain – relieved by treatment (Kobesová, 2007)
· Following visceral mobilization post-operative adhesion severity & number of adhesions were significantly lower, in a rat model (Bove & Chapelle 2012)
· Connective tissue massage (‘skin rolling’) has been shown, via ultrasound imaging, to modify collagen density. (Pohl 2010)
· “Evidence supports the possibility that ligamento-muscular reflexes can have inhibitory effects on muscles associated with that joint.”(Solomonow 2009)
· “Strain direction, frequency and duration, impact important fibroblast functions known to mediate pain, inflammation and ROM” (Standley & Meltzer 2008)
· Fascial Manipulation (FM®)) studies suggests that fascia involves specific organizational relationships with associated muscles. (Borgini et al 2010)
· Tool assisted treatment (e.g. Graston) produces mechanical deformation that influences extracellular matrix, modulating synthesis of proteoglycans and collagen, apparently influencing connective tissue rehabilitation (Chiquet 2003)
· Klingler (2012) reports that heat in the therapeutic range, relaxes many fascial contractures associated with myofascial dysfunction. (IN PRESS)
