Clinical ConsiderationAs is the case with other tissues, neural tissue functions best when free ofrestriction or compression. Neural compression is linked to variousneuropathies (e.g. carpal tunnel, sciatica, thoracic outlet). Neural sensitivityto compression ought to be taken into consideration during manualtherapies. It is important to approach distressed neural tissues gently andfrom angles that avoid compressing the nerve further. Additionally,distressed nerves do not tolerate much stretch – treatment considerationsare covered in more detail in Chapter 9.

Proprioceptive DisinformationDensification, adhesions, fibrosis or excessive scarring can impactproprioception (Stecco et al. 2006, Stecco et al. 2010, Fourie 2012). Bindingmay occur among layers that should stretch and slide/glide on each other,distorting myofascial relationships which, in turn, can alter muscle motorfunction and proprioception (Fourie 2009, Stecco & Stecco 2009).Recall from Chapter 2, when challenged by stretch or movement, dense and/orrestricted fascia may alter proprioceptive afferent signals that lead to eventualabnormal biomechanics, aberrant movement patterns, muscle compensation,joint distress and pain (Bouffard et al. 2008, Stecco et al. 2010).Normal tissue viscoelasticity is essential for proper neurological functioning,including proprioception (Stecco 2004, Stecco et al. 2010). In the absence ofnormal physiological elasticity, receptors embedded within the fascia may alsobe in an active state, even at rest. Any further stretching – even that produced bynormal muscular contraction – could cause excessive stimulation withconsequent propagation of nociceptive afferents. Further, over a certainthreshold (i.e. consistent stimulus over time), all receptors can potentiallybecome algoceptors (pain receptors) in response to consequent propagation ofnociceptive signals (Ryan 2011).

Clinical Consideration

As is the case with other tissues, neural tissue functions best when free of

restriction or compression. Neural compression is linked to various

neuropathies (e.g. carpal tunnel, sciatica, thoracic outlet). Neural sensitivity

to compression ought to be taken into consideration during manual

therapies. It is important to approach distressed neural tissues gently and

from angles that avoid compressing the nerve further. Additionally,

distressed nerves do not tolerate much stretch – treatment considerations

are covered in more detail in Chapter 9.
