Fibromyalgia Activity Study With Transcutaneous Electrical Nerve Stimulation
In Brief
A clinical study evaluating TENS for Fibromyalgia. Completed, enrolled 301 participants across 2 sites.
Detailed 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
