PHTY209 Lecture Notes - Lecture 12: Neuropathic Pain, Biopsychosocial Model, Noxious Stimulus
Document Summary
Example: pre-op anxiety associated with higher pain intensities after surgery and 1 year down track (tkr). Physiological: muscle tension, sns, endocrine (stress and cortisol) = poor tissue healing. E(cid:373)otio(cid:374)al respo(cid:374)se: fear of (cid:373)o(cid:448)e(cid:373)e(cid:374)t do(cid:374)"t (cid:449)a(cid:374)t to (cid:373)o(cid:448)e the k(cid:374)ee not walking on it.

Fundamental principle of this approach is that pain is produced by the brain when it perceives that danger to body tissue exists and that action is required. Pain is an output of the brain. It is the combination of cortical areas that when activated produce pain. This model when used to guide assessment: requires that we assess all dimensions of the pain experience (medial and lateral pain system and the brain areas involved = multidimensional pain output.
