Primary Outcome Measures:
  • Pain rating to Temporal Summation and Diffuse Noxious Inhibitory Control (DNIC) as measured by a visual analogue scale [ Time Frame: Measured at last study acupuncture session (6 weeks post enrollment) ]

Secondary Outcome Measures:
  • Change in Fibromyalgia Impact Questionnaire [ Time Frame: Change from first to last study treatment session (6 weeks) ]
  • Change in Brief Pain Inventory [ Time Frame: Change from first to last treatment session (6 weeks) ]

Enrollment: 10
Study Start Date: April 2010
Study Completion Date: August 2012
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Acupuncture Procedure: Acupuncture
Treatment given twice per week for 4 weeks

Detailed Description:
Patients and healthy controls will be enrolled in the study for a total of 6 weeks. This includes a screening and baseline visit, 8 acupuncture treatments (2 per week for 4 weeks), and a follow-up visit and treatment 1 week after completion of the study treatment sessions. To determine the effects of acupuncture on pain, patients and healthy controls will undergo psychophysical pain testing at four points throughout the study: Baseline (appointment 1), post-treatment 1 (appointment2), post treatment 8 (appointment 9), and at the final follow-up session (1 week from last treatment - appointment 10).Participants will also fill out a brief report on pain, sleep, and functioning on a palm pilot. This is expected to take less than 2 minutes per day and will occur throughout the 6 week study period.
