- Abstract
The capacity of magnets to reduce pain sensitivity was assessed in 97 pain-free undergraduate students (71 women and 26 men). Most participants received insoles that contained active or inactive magnets, and instructions designed to influence their expectations of whether their insoles were active or inactive. Insoles were applied to the soles of participants' feet. A control group did not receive insoles. Pain was induced in two different ways: an ice hath of 0-2°C induced cold-pressor pain and a clamp-induced pressure pain. Pain perception was measured by latencies and by participants' ratings on visual analogue scales. Magnets did not increase latencies to pain threshold and tolerance or decrease ratings of pain intensity and unpleasantness. A reverse placebo effect occurred for pressure pain threshold latencies. Gender differences were consistent with previous research; compared with men, women rated the pressure pain as more unpleasant.
