Imagery Reduces Pain, But You Wouldn’t Know It from the Biochemistry

13 Dec

Researchers from Kent State University in Ohio study examined the impact of a guided imagery intervention over an 8-week period on pain and pain disability in people with chronic non-cancer pain; and analyzed the mediating effects of neuro-endocrine and neuro-immune functioning on the effectiveness of the guided imagery.
 
A simple, interrupted time-series design (12-week period) was used. The guided imagery was introduced at Week 4 and used daily by 25 participants for the remaining 8 weeks.  Pain intensity and pain disability were measured at the beginning of the study and at six repeated 2-week intervals.

Measures of hypothalamic-pituitary-adrenal (HPA) axis activation (plasma cortisol), immune-mediated analgesia (lymphocyte counts and proliferation), and immune-mediated hyperalgesia (interleukin-1β) were obtained at the beginning of the study and at Week 11.

Pain levels were lower after the introduction of the imagery at Week 4 (Wilks' λ = 52.31; df = 2, 22; p = .000), as was pain disability (Wilks' λ = 5.98; df = 6, 18; p = .001).

Investigators determined that the guided imagery intervention was effective in reducing pain intensity and pain disability over the 8-week period; however, the neuroendocrine and neuroimmune results did not reflect this with decreased HPA axis activation, improved immune-mediated analgesia, nor reduced immune-mediated hyperalgesia.
