The investigators hypothesize that acupuncture modifies the DNIC efficiency and that DNIC can serve as a predictor to identify 'good responders' to acupuncture early in therapy.

Primary Outcome Measures:
  • Diffuse Noxious Inhibitory Control Efficiency [ Time Frame: Week 0, 2, 4, 6, and 12 of acupuncture therapy ] [ Designated as safety issue: No ]
    The efficiency of diffuse noxious inhibitory control (DNIC) is a measure of one's ability to inhibit pain perception. DNIC efficiency is assessed by a psychophysical test that involves a heat thermode as the "test stimulus" and a warm water bath as the "conditioning stimulus". The results of this test will be used as the primary outcome measure.
