For people with the mysterious chronic pain condition fibromyalgia, researchers say nerve stimulation may offer some relief. In a recent study, use of TENS — transcutaneous electrical nerve stimulation — during movement or activity was shown to significantly reduce pain associated with fibromyalgia after just four weeks. Dr. Lesley Arnold, who was not involved with the new study, lauded its outcomes. “The improvements in pain and fatigue were remarkable,” she said. Arnold, a professor of psychiatry and behavioral neuroscience at the University of Cincinnati College of Medicine, suggested that the study may help guide physicians in use of TENS for symptom management. TENS uses a battery-operated machine to deliver electrical currents via electrodes attached to the skin. This is believed to activate nerve pathways that inhibit pain. People with fibromyalgia are encouraged to engage in physical activity as a way to manage their symptoms. But, paradoxically, movement can be painful for them. In the study, researchers randomly divided more than 300 women with fibromyalgia into three groups: active TENS; placebo (sham) TENS; or no TENS. Those in the TENS groups were instructed to use the device over four weeks, at home, for two hours daily during activity. The patients were told to apply the device’s electrodes to two specific areas along the back — one upper and one lower — and to activate the machine… read on >
