RhoGam is a vaccine like globulin shot that was developed in the late 1960s to keep a Rh negative woman from becoming sensitized to the Rh positive blood of her fetus in the unlikely event blood mixing occurs. Rhogam works very much like an immunization.
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.
The TENS unit did not seem to have an effect on the length of labor, interventions used or the ultimate well-being of mother and baby. Other uses for transcutaneous electrical stimulation include increasing the range of motion for individuals who suffer from adhesive capsulitis (frozen shoulder).
