The Dual Nature of the Caretec II TENS/EMS

Some people only need the pain relief of a TENS device. Others just seek the rehabilitation properties of an EMS unit. Yet there is a third group of individuals who stand at the intersection of the first two, and who crave for some sort of hybrid that brings together the features of both types of therapies. The answer to their problem comes in the form of the Caretec II TENS/EMS machine. TENS and EMS live together in the Caretec II like ebony and ivory do in a piano keys, and they are just as different, though working towards one ultimate goal. That objective is to achieve the physical betterment of the user.
Both techniques deal with the alleviation of pain. The difference is that TENS helps to decrease chronic pain (such as arthritis or and back or neck pain) so that the user can perform daily actions unimpaired by joint or muscle problems. EMS, on the other hand, has to do with the pain caused by a muscular injury (whether it is due to accident or sporting activity) with a view to rehabilitate the muscle and return it to mobility. In either case, both TENS and EMS aim at getting the patient back on their own two feet.

Furthermore, the two technologies have an influence on the signals that are transmitted between the nerves and the brain, by way of electrical impulses sent through the skin. TENS alters the way that the nerves perceive pain, so that they stop sending pain signals to the brain, effectively providing relief. And EMS sends signals to the muscle ordering it to contract in such a way that the muscle receives the signal as if it was emitted by the brain itself. This way the muscles contracts and relaxes alternatively and constantly, thus exercising passively.  
One of the things that they do have in common is that the user should consult a doctor before applying either therapy. That requirement does not change when a Caretec II TENS/EMS is involved. A personal physician and/or physical therapist will be able to guide you through treatment and help you make any adjustments deemed necessary. Needless to say that no two people experience chronic pain equally and that injuries affect all patients differently. Similarly, users react variously to pain management, and that’s why a professional must always be at hand to answer your questions and clear up your doubts.
