Pathophysiological Consideration
Trauma, mechanoreceptors and proprioceptive disinformation
Trauma, including pathophysiological scars, can result in aberrant
mechanoreceptor function. Fibrosis and adhesions that occur with
pathological scars can lead to innocuous mechanical stimuli being
perceived as noxious, resulting in the subsequent relay of incoherent or
misinformation to local, regional, or central nerve centers (i.e.
proprioceptive disinformation). Under- or overestimation of the mechanical
stimuli received results in inappropriate muscular reactions, such as
interference with recruitment and timing of recruitment, which endangers
equilibrium, coordination and stability. Consequently, proprioceptive
disinformation can adversely impact the rehabilitative process or increase
the incidence of comorbid injuries (e.g. falling with subsequent sprains or
fracture).
The interoceptive system, considered the substrate of recognition of self, plays a
fundamental role in the relationship between one’s subjective state of well-being
and physiological health. Volitional cortical control in humans can directly
modify homeostatic integration (Petrovic et al. 2002, Craig 2003, Critchley et al.
2002, Damasio et al. 2000, Derbyshire et al. 2003). This supports that how we
feel about how we feel can influence how we function, right down to the
physiological level.
