Electrotherapy for pain has been in the medical news for decades now. It first became interesting to doctors when they were using it to make measurements about patient's tolerances before surgeries. Eventually, the doctors had enough people come back to them and decline the surgery for which the electrotherapy—or what would eventually become electrotherapy—was being employed as a test. This led doctors to believe that there was real merit in using electricity to treat certain type of pain and, today, it's a very common type of treatment.
The TENS unit—an acronym for transcutaneous electrical nerve stimulation—is a portable device that people use to provide themselves with electrical stimulation in the painful areas. These devices are very compact. Today, they come in both digital and analog models. The analog models have a more varied range of adjustments but the digital models can be adjusted more precisely. The analog or detail aspect of these devices, however, does not actually provide the treatment, so it's really just a matter of preference as to which is the best for the patient.
The devices used for electrotherapy were initially very expensive. Over time, however, the prices dropped to the point where most people can afford one of these units if they want one. In fact, purchasing these units online allows patients to get them for very affordable prices; less than the cost of going out for dinner and seeing the movie, in most cases. These devices can last for many years and, because of that, people sometimes end up saving money compared to what they would pay if they were paying for analgesic treatments, such as drugs.
If you are interested in electrotherapy, make certain that you contact your physician before you begin any program. There are some considerations that you have to take into account. For example, if you have a pacemaker, you have to be absolutely certain that the electrotherapy is not going to interfere with the function of that device. There are also certain areas of the body where you must never use any type of electrical current in any way. Obviously, the area near the heart is one of these problem spots.
This type of therapy has gotten good results for people who suffer from chronic back pain, other musculoskeletal issues and the type of problems that are generally treated with chiropractic care, massage therapy or pain relieving medications. If you think it would work for you, consult your physician or your chiropractor.
