Brief Summary

Pain associated with fibromyalgia interferes with daily function, work, and social activities resulting in a decreased quality of life. People with fibromyalgia also have a significant amount of fatigue and a fear of movement. People with fibromyalgia show enhanced excitability of pain neurons in the central nervous system and reduced pain inhibition. Therefore, one of the main treatments for patients with fibromyalgia must focus on pain relief to allow the person to function more independently both at home and at work. Transcutaneous electrical nerve stimulation is used by health professionals to deliver electrical stimulation through the skin for pain control. Basic science studies, from the PI's laboratory show that TENS activates descending pain inhibitory pathways to inhibit excitability of pain neurons. Thus the ideal patient population for the treatment of TENS would be one in which there is enhanced central excitability and reduced inhibition; fibromyalgia is such a condition. Hypothesis: The investigators hypothesize that application of Transcutaneous Electrical Nerve Stimulation (TENS) to patients with fibromyalgia will reduce resting and movement-related pain and reduce central excitability by restoring diffuse noxious inhibitory controls (DNIC), and that this decrease in pain and/or central excitability will reduce fatigue and fear of movement, thereby improving function and quality of life

Outcome Measures

Primary Outcomes (2)

  • Pain Rating With Movement (0-10 Low to High Scale) During Six Minute Walk Test

    Numeric rating scale of 0-10 (low to high scale) for pain with movement during six minute walk test; Intention to treat analysis corrected for site (Iowa and Vanderbilt) differences. Mean change (from baseline, Visit 2) at Visit 3 (after 4 weeks of home TENS use, or placebo TENS, or no TENS) and at Visit 4 (after 4 weeks of home TENS all groups) with 95% adjusted confidence intervals. Change scores are presented for the randomized phase between Visit-2 and Visit-3, and for the difference from baseline at Visit 4 when all subjects received active-TENS. p-values represent post hoc comparisons between groups

    Time Frame: Baseline (Visit 2), 4 weeks (Visit 3, randomized to 3 groups), and 8 weeks (Visit 4, all groups home TENS

  • Pain Rating With Movement (0-10 Low to High Scale) During Five Time Sit to Stand Test

    Numeric rating scale of 0-10 for pain with movement with five time sit to stand test. Intention to treat analysis corrected for site (Iowa and Vanderbilt) differences. Mean change (from baseline, Visit 2) at Visit 3 (after 4 weeks of home TENS use, or placebo TENS, or no TENS) and at Visit 4 (after 4 weeks of home TENS all groups) with 95% adjusted confidence intervals. Change scores are presented for the randomized phase between Visit-2 and Visit-3, and for the difference from baseline at Visit 4 when all subjects received active-TENS. p-values represent post hoc comparisons between groups

    Time Frame: Baseline (Visit 2), 4 weeks (Visit 3, randomized to 3 groups), and 8 weeks (Visit 4, all groups home TENS)
