ANALGESIC TENS CONTROVERSY OVER ITS USEFULNESS
Keywords:
TENS, pain, efficacy.Abstract
The rectangular biphasic asymmetric current (analgesic TENS) is one of most important tools for pain treatment, but in the professional's clinic practice and in different authors which's have studied this question we see a great range of values of the parameters of this current wiches they use to treat each type of pain. This has generated a strong controversy about the efficacy of this current. In this article we present a revision about this controversy at the moment, due to some studies defends the efficacy of TENS in chronic pain, in induced pain and in acute pain, although others refuse this efficacy. In order to answer this question a bibliographic review in several databases (Pubmed, Elsevier, Cochrane and Scopus), using TENS, pain, efficacy, chronic pain, induced pain, acute pain and posttraumatic pain as key words have been carried out. We believe that analgesic TENS efficacy in the different types of pain has a great clinic reality, that, apparently, it has been insufficient studied from the scientific evidence.
