Primary Outcome Measures

Name	Time	Method
Change in Fibromyalgia Impact Questionnaire-Revised (FIQR) score	baseline (Visit 3, day 8) to post-treatment (Visit 7, approximately day 36).	The FIQR is 21 questions. Each question has 11 boxes similar to a visual analog scale. Questions include the difficulty associated with various physical activities and the severity of symptoms. The score for the questions is on a scale from 0 - 100, where lower scores represented better functional status.

Secondary Outcome Measures

Name	Time	Method
Change in Brief Pain Inventory (BPI) score	baseline (Visit 3, day 8) to post-treatment (Visit 7, approximately day 36).	The BPI consists of 11 questions and assesses for the presence of pain, pain intensity (i.e., worst, least, average, current) and functional interference from pain. A higher score indicates more pain.
