Brief Summary:
This study assesses the benefits of intervention with gabapentin, Osteopathic Manipulative Medicine or both for improvement of the symptoms of Fibromyalgia. This study also seeks to determine whether these treatments will decrease the number and severity of tender points, improve structure, function and the overall pain level of each patient from the baseline of the study to the end. This study is designed to evaluate whether subjects subjectively experience an improved quality of life and increased function as a result of these interventions corresponding to objective improvements.

Condition or disease Intervention/treatment Phase
Fibromyalgia Drug: Gabapentin Procedure: Osteopathic Manipulative Medicine Other: Gabapentin and Osteopathic Manipulative Medicine Phase 3

Detailed Description:

An 8-week, randomized, study was designed to compare gabapentin (900 mg/day) (n = 8 patients) with OMM (n = 11 patients) with Combined treatment of gabapentin (900 mg/day) plus OMM (n = 7 patients) for efficacy and safety in treating pain, fatigue, depression and function associated with fibromyalgia.

The primary outcome measures were measured during week 2 and week 8 to evaluate efficacy of each arm and compare efficacy between each arm at improving structure, function and pain. The Baker Wong Brief Pain Inventory (BPI) was evaluated weekly for average pain severity score (range 0-10, where 0 = no pain and 10 = pain as bad as you can imagine). Fibromyalgia Impact Questionnaire (FIQ) a tool that evaluates function and health status was administered at week 2 and week 8 for comparison of functioning at the baseline and end of the study. The total number of Tender Points (0-18) as determined by the American College of Rheumatology was counted at week 2 and week 8 to compare number of tender points from the baseline to the end. Dolorimetry in Kg/cm2 as measured by the Fischer Dolorimeter were measured on the 4 most severe tender points at week 2 and week 8 to compare severity of tender points from baseline to end of study. The Osteopathic Structural Examination which measures free range of motion of joints in degrees was measured with goniometry at week 2 and week 8 to evaluate degrees of free range of motion improved from baseline. The Clinical Global Impression which is a likert scale of 1-5 asking patients to evaluate how they feel about their overall health was taken at week 2 and week 8 to see if overall subjective thoughts of health were improved from baseline.
