TENS Therapy and Iontophoresis: All You Need to Know about Analgesic Electrotherapy

Analgesic electrotherapy is a sufficiently precise term to define an anti-pain medication (antalgic) based on the electrical shock (electrotherapy) administration. However, the difference in understanding the underlying circumstances of antalgic electrolysis cannot be easily understand, with what benefits and contraindications, by using biological mechanisms, for all this information, the understanding of the term is not enough. In this post, we will therefore try to understand how many forms of antalgic electrotherapy exist, how they differ and many other useful information for those who would undergo an antalgic electrotherapy cycle.


What is Analgesic Electrotherapy?

That antalgic electrotherapy is a pain relieving treatment that is based on the administration of analgesic. We already mentioned it and moreover, very intuitive for anyone, we are starting to introduce more demanding concepts, such as the difference between AC and DC (or galvanic) current treatments. What is the difference? It is said that in the case of direct current, we have an electric current characterized by a constant flow of intensity and direction, while in the case of the alternating type, we have an alternation of positive pulses and negative pulses. If this is the difference from a purely physical point of view between the two currents, the one from the medical point of view is that while the continuous currents are used to favor the absorption of certain drugs (primarily painkillers and anti-inflammatory drugs). On the other hand, the alternate type (to aid muscle contraction) are found to be more effective in biodynamic therapy and TENS.

Antalgic Electrotherapy: General Information

Until now, we have limited ourselves to explaining that antalgic electrotherapy is used to reduce pain and exploits two types of different (alternating and continuous) currents to produce two different types of results (muscle contraction or drug absorption). We have not said anything until now about the pathologies and disorders that we can treat effectively by using antalgic electrotherapy. Antalgic electrotherapy is used to treat conditions such as muscular, painful and nervous (mainly neuritis) and radiculitis (such as sciatica). When we talk of muscle-related disorders or in any case of the nerves and in general of the musculoskeletal system, it is very likely that the use of antalgic electrotherapy is very advisable. Of course, there are several forms of electrotherapy, so in the next paragraphs we will try to describe them in a simple and accessible way in detail.


Diadynamic Antalgic Electrotherapy

These are currents formed by unidirectional and mainly positive pulse waves are always used to reduce pain (muscular) and are widely used in tendinitis (elbow, wrist, shoulders, knee and ankle) or in any case to treat trauma and joint disorders (both acute and chronic).

Lumbar and Cervical Lymph Nodes

Let’s start by saying that TENS is the English acronym for Transcutaneous Electrical Nerve Stimulation, which is about┬áthe use of electric current produced by a device to stimulate the nerves for therapeutic purposes. This technique is no longer so widely used as in the past since its ability to produce benefits in the patient is limited over time, but is still indicated in the treatment of certain diseases (mainly lumbar and cervical tract) by virtue of its ability to effectively reduce the pain (though, as mentioned, with only temporary results)


Interferential Antalgic Electrotherapy

This type of treatment utilizes the ability of low frequency electric waves to penetrate deep into tissues with the aim of relieving pain or having absolute relief; interferential antalgic electrotherapy is now largely used to treat disorders such as chronic cervicalgia, backache and some forms of arthritis.


Antalgic electrotherapy: Iontophoresis

Finally, Iontophoresis is a form of antalgic electrotherapy used to help absorb certain drugs more deeply into the tissues.
