However, some new research has shown that TENS may be effective for reducing pain in people who have fibromyalgia, especially in combination with other treatments, such as exercise. Fibromyalgia is often treated with various medications to relieve pain and improve sleep.
Results found that the intensity of stimulation is a critical factor in the success rate of pain treatment using a TENS unit. Successful treatment using electrical stimulation for the relief of musculoskeletal pain was consistently demonstrated for both acute and post-operative conditions.
