Session 1 = prior to use of Lidoderm therapy; Session 2 = after 2 weeks of Lidoderm therapy. Pain Int. = mean pain rating during the scan; Pain Int./Pr = mean pain rating during the scan divided by normalized applied pressure.VAS = visual analog scale; Unpleas = unpleasantness; VAS, Affective and Sensory are from McGill short form. N = Neuropathic Pain Scale; W = WOMAC. All parameters are expressed as μ ± S.D. p values were computed using a paired t-test. | |||||||
