TENS is one of the few treatments that specifically targets movement-evoked pain and fatigue. Credit: Neuroscience News<\/p>\nSummary: For the millions living with Fibromyalgia, the greatest paradox is that exercise is the best medicine, yet movement itself causes agonizing pain and crushing fatigue. A real-world clinical trial has found a simple, drug-free solution.<\/p>\n
By adding TENS (transcutaneous electrical nerve stimulation) to standard physical therapy, patients saw a significant reduction in movement-evoked pain and\u2014most notably\u2014fatigue. The study, involving 384 participants across 28 clinics, proved that TENS is as effective as FDA-approved medications but with a \u201cdose-dependent\u201d benefit that doesn\u2019t fade over time.<\/p>\n
Key Facts<\/p>\n
The Fatigue Breakthrough: While many treatments target pain, this is one of the first to significantly reduce fatigue, a primary barrier for fibromyalgia patients.Real-World Success: Unlike many lab-only studies, this \u201cFM-TIPS\u201d trial took place in everyday clinics across the Midwest, proving the treatment works in the \u201cmessy\u201d reality of daily life.No Tolerance Build-up: Unlike opioid or non-opioid medications, which often require higher doses over time, TENS maintained its effectiveness for at least six months.The 80% Rule: After the trial, 80% of participants found TENS helpful, and 70% reported feeling better overall, leading to high long-term adherence.<\/p>\n

Adding\u00a0TENS (transcutaneous electrical nerve stimulation)\u00a0to outpatient physical therapy\u00a0reduced\u00a0movement-based\u00a0pain and fatigue in patients with fibromyalgia,\u00a0and\u00a0the\u00a0effects lasted for at least\u00a0six\u00a0months, according to\u00a0a new study led by researchers\u00a0at\u00a0University of Iowa Health Care.\u00a0\u00a0<\/p>\n
The\u00a0study,\u00a0led by\u00a0Kathleen Sluka,\u00a0PT,\u00a0PhD,\u00a0is\u00a0the first\u00a0real-world trial of TENS for fibromyalgia. The findings, published on March\u00a027\u00a0in the journal\u00a0JAMA Network Open,\u00a0show that TENS is a safe, effective, inexpensive, and readily available treatment for\u00a0fibromyalgia, a\u00a0chronic\u00a0condition\u00a0that causes pain, tenderness, and fatigue throughout the body.\u00a0<\/p>\n

\u201cIt is one of the few treatments that specifically targets movement-evoked pain and fatigue,\u00a0which are\u00a0major\u00a0barriers to participation in daily activities,\u201d says Sluka, UI professor of physical therapy and rehabilitation science.\u00a0<\/p>\n
TENS\u00a0uses a\u00a0small device\u00a0with adhesive electrodes\u00a0to send\u00a0mild\u00a0electrical\u00a0pulses\u00a0through\u00a0the\u00a0skin\u00a0to block or\u00a0reduce\u00a0pain.\u00a0The study found that the effect of TENS for reducing pain was similar, if not better, than\u00a0current\u00a0FDA-approved medications\u00a0for fibromyalgia.\u00a0<\/p>\n
\u201cWe were\u00a0excited\u00a0to see that\u00a0patients\u00a0also\u00a0had less fatigue,\u201d Sluka added. \u201cRight\u00a0now,\u00a0there are no good treatments for fatigue.\u00a0So,\u00a0the fact that we had anything that touched the fatigue was\u00a0pretty powerful.\u201d\u00a0<\/p>\n
Fibromyalgia: complicated, misunderstood,\u00a0and hard to treat\u00a0<\/p>\n
Fibromyalgia affects about 4%\u00a0to 7% of the population. It significantly\u00a0impacts\u00a0a person\u2019s physical function, cognitive\u00a0abilities,\u00a0and sleep. In addition to chronic pain, a key feature of the condition is whole-body fatigue, which interferes with day-to-day life and contributes to patients\u2019 inability to concentrate and\u00a0perform functional activities.\u00a0<\/p>\n
Exercise is often the first line of treatment recommended to people with fibromyalgia, and research has shown that it can be beneficial. However, fibromyalgia causes fatigue and pain, which is\u00a0a key\u00a0reason why\u00a0the research team focused on alleviating pain with movement.\u00a0<\/p>\n
\u201cPain with movement hinders\u00a0a person\u2019s\u00a0ability to participate in an effective exercise program and\u00a0do their day-to-day activities.\u201d Sluka says.\u00a0\u00a0<\/p>\n
Science translated to real-world benefit\u00a0<\/p>\n
Sluka and her colleagues have spent decades\u00a0studying\u00a0the biological mechanisms affected by TENS, developing the ideal parameters of TENS stimulation and testing the efficacy of TENS\u00a0for treating chronic pain\u00a0and fatigue\u00a0in\u00a0human\u00a0trials.\u00a0<\/p>\n
They have\u00a0previously shown\u00a0that\u00a0under the ideal conditions of a randomized, controlled clinical trial,\u00a0TENS in conjunction with physical therapy can significantly decrease movement pain.\u00a0<\/p>\n
The new\u00a0Fibromyalgia TENS in Physical Therapy (FM-TIPS) study\u00a0was\u00a0designed to\u00a0test the effect of TENS\u00a0under\u00a0real-world\u00a0conditions.\u00a0The\u00a0study was conducted in 28\u00a0outpatient physical therapy clinics across six health care systems\u00a0in the Midwest,\u00a0and included\u00a0384\u00a0people of different ages, education levels, and socioeconomic backgrounds. Almost 50% of the participants were from rural areas.\u00a0\u00a0<\/p>\n
\u201cIt was\u00a0a challenge\u00a0to recruit participants for this study, but the clinics and the physical therapists we worked with were great. This would never have happened without them,\u201d Sluka says.\u00a0<\/p>\n
The clinics were randomized to provide either physical therapy\u00a0(PT)\u00a0with TENS or physical therapy alone. In the\u00a0PT-TENS group, participants\u00a0were asked to use TENS for two hours a day\u00a0for\u00a0six months.\u00a0That time could be split into short periods or done all at once. The TENS electrodes were placed on the upper and lower\u00a0back\u00a0and\u00a0delivered a mixed frequency signal at an intensity as\u00a0strong as the participant could tolerate.\u00a0<\/p>\n
After\u00a060\u00a0days, movement-evoked pain during TENS treatment was significantly\u00a0improved\u00a0in the PT-TENS group.\u00a0Adding TENS also significantly reduced resting pain and resting and movement-fatigue.\u00a0In contrast, participants who\u00a0received only\u00a0physical\u00a0therapy had no change in\u00a0their\u00a0movement-evoked pain.\u00a0\u00a0<\/p>\n
The response also was dose-dependent,\u00a0with people who used TENS daily for\u00a060 days\u00a0having the best outcomes.\u00a0<\/p>\n
Unlike many pain-relieving drugs\u00a0that can become less effective over time as the body develops a tolerance for the medication, the study shows that over time, TENS\u00a0maintained\u00a0its ability to improve pain and fatigue at a significant level.\u00a0<\/p>\n
After the primary endpoint at day 60, the PT-only group was also given\u00a0TENS,\u00a0and\u00a0all the\u00a0participants\u00a0continued\u00a0in the study\u00a0for another\u00a0four\u00a0months.\u00a0\u00a0<\/p>\n
\u201cWhen we gave the PT-only patients the TENS unit and they started using it, we also saw the same improvements\u00a0as the PT with TENS patients, which is powerful,\u201d\u00a0Sluka says.\u00a0<\/p>\n
Overall,\u00a0the study\u00a0showed that\u00a080% of patients found TENS helpful. At\u00a0six\u00a0months, 80% were still using TENS once a week, and over 70%\u00a0reported\u00a0they\u00a0felt\u00a0better after using TENS.\u00a0<\/p>\n
TENS adds benefit\u00a0\u00a0<\/p>\n
Dana Dailey,\u00a0PT, PhD,\u00a0UI assistant research scientist and\u00a0the first\u00a0author\u00a0of\u00a0the study,\u00a0notes that\u00a0it\u2019s\u00a0important for people to realize that the benefit of TENS comes from using it as a part of a total treatment planthat\u00a0includes\u00a0physical therapy.\u00a0\u00a0<\/p>\n
\u201cUsing TENS on its own will not give the same benefits,\u201d\u00a0Dailey says.\u00a0\u201cHowever, the study shows that TENS provides an added benefit on top of any relief from other treatments.\u00a0All\u00a0the study participants were also using pain medications and receiving physical therapy, yet TENS still provided\u00a0additional\u00a0relief.\u201d\u00a0<\/p>\n
Fibromyalgia often needs multiple interventions to help patients feel less pain and fatigue and improve their overall function. The\u00a0new\u00a0findings suggest that TENS could be particularly helpful as a part of a multipronged approach because it can be\u00a0safely\u00a0and\u00a0easily used as a self-management tool that uniquely targets movement-associated pain and fatigue.\u00a0<\/p>\n
\u201cOften,\u00a0when you move a randomized, controlled clinical trial into a real-world setting, it\u00a0doesn\u2019t\u00a0work because there\u00a0are too\u00a0many confounding factors. But this intervention still works,\u201d Sluka says.\u00a0\u201cNot only did the treatment reduce movement pain and fatigue during the testing period, but patients continued to use it at six months.\u201d\u00a0<\/p>\n

Key Questions Answered:Q: Can I just buy a TENS unit and skip physical therapy?<\/p>\n
A: The researchers are clear on this: No. The study found that TENS provides an \u201cadded benefit\u201d on top of physical therapy and medication. It works best as a \u201cself-management tool\u201d that allows you to actually get through your PT and daily activities without the usual \u201cflare-up\u201d of pain.<\/p>\n
Q: How exactly does a little zap help with whole-body fatigue?<\/p>\n
A: Fatigue in fibromyalgia is often linked to the brain being in a constant state of high-alert due to chronic pain. By using TENS to block those pain signals, the nervous system can finally \u201ccalm down,\u201d which preserves the energy that would otherwise be spent processing pain. It\u2019s essentially a \u201cpower-save mode\u201d for your brain.<\/p>\n
Q: Will the \u201czaps\u201d stop working if I use it every day?<\/p>\n
A: Surprisingly, no. While your body gets used to drugs (tolerance), the study showed that the response to TENS was dose-dependent. Those who used it consistently for two hours a day for 60 days had the best outcomes, and the relief lasted through the full six-month follow-up.<\/p>\n
