TENS is short for Transcutaneous Electrical Nerve Stimulation, but it has been around for decades and has several different applications. It has recently become very popular for use by back pain sufferers as a treatment. In addition, many hospitals now offer TENS as part of their therapy packages. There are several benefits to using a TENS device, and I will explain some of them here. You should also be able to find information about TENS machines that are for home use and those for use in a hospital.
You only need a small amount of TENS-machine to start having effective therapy. You should buy yourself a TENS unit that has at least four electrodes and a contact electrode. It is best to find a unit with at least ten electrodes, as more electrodes will allow for more stimulation patterns. You only need to apply direct electrical current for about thirty seconds each session, though it may take longer, up to an hour or two. It is good practice to take frequent ten-minute breaks between sessions, though you can use TENS as often as you like.
The actual stimulation occurs when the patient applies pressure to the contact electrode using their palm or fingers. This provides a relaxing sensation that can sometimes provide a feeling of tingling sensation. The electrical impulses from the unit run through the four electrodes and travel up the nerves to the brain. They stimulate the nerve endings in the skin and the muscles and are in the process of relieving pain. This type of therapy offers excellent relief to chronic sufferers because of the direct, soothing quality of the stimulation.
A word of caution, though: TENS-machine are not suitable for everyone, even though they have a shallow risk of side effects. For anyone with pacemakers, epilepsy, diabetes, epilepsy, heart problems or breathing difficulties such as asthma, TENS machines may not be a suitable treatment. These conditions require separate, high-level care that the machines cannot provide. People with psychiatric disorders may also be put on hold whilst the electrodes are attached to their body, as they experience brief periods of muscle spasms or fear. For these patients, it may be better to seek advice from a trained healthcare professional or wait until the therapy effects wear off. The same goes for those with epilepsy, breathing difficulties or serious health concerns that could prevent them from using ordinary, medical-grade TENS.
However, some people may find that the relief of chronic pain signals gives them a sense of empowerment, which often leads to an increased desire to pursue their chosen treatment. Unfortunately, this could lead to a dependence on the device, so to avoid this, first-time users need to undergo training in its use or at least familiarize themselves with its various options. This means that users should be made aware of the difference between direct and alternating current and its potential side-effects and advantages over traditional forms of pain relief such as inhalation of oxygen or placing one’s hands directly on the nerve. In addition, the therapeutic effect of a TENS machine depends largely on the type of stimulus it is used on, so the electrodes must be placed precisely where they will have the most excellent effect.
To produce the soothing, pulsating tingling sensation required by TENS, the electrodes are attached to the patient’s body in such a way that the two conducting wires are directly connected to the skin. When the electrical current is applied to these electrodes, the conductors trigger the nerve endings in the skin, which sends out this sensation of a tingling sensation resulting from the electrical stimulation. While this is the general concept of how a tingling sensation occurs, there is much more to how a patient feels the effects of this new therapy. As mentioned previously, this sensation often results from direct contact with the stimulated skin, and the sensations can be quite different depending on the area of the body being treated. A TENS machine can also be used to treat diseases and conditions where conventional medicine has proven ineffective, so it is no wonder that it has become such a popular option.
