Understanding the Types of Electrodes in Electrotherapy

Understanding the Types of Electrodes in Electrotherapy
Taikhum Sadiq

Electrotherapy involves the use of electricity in the treatment of certain ailments and to provide a therapeutic impact on the body. Painful nerve conditions may get relief from electrical stimulation of the body, which blocks pain signals. Electrotherapy is also said to speed up wound healing and involves several treatment modalities. It is conducted with the help of electrotherapy electrodes, which are electrical conductors that are used to make contact with the non-metallic part of an electric circuit.

What is Electrotherapy used for?

Electrotherapy machine may be used for the following:

  • Muscle spasm relaxation
  • Pain management
  • Improved blood circulation
  • Lymphatic drainage
  • Incontinence
  • Chronic and acute edema
  • Muscle rehabilitation
  • Neuromuscular dysfunction
  • Improvement of the range of motion and tissue repair
  • Retard muscle atrophy

What is the link between Electrodes and Electrotherapy?

Made of conducting elements, electrodes are small terminals that help transfer electric currents to non-metallic elements like vacuum, semi-conductors, etc. They are used to transfer ionic current to the human body. Amplified within the body, electrodes can be used to detect any kind of anomaly in the muscular, nervous, or cardiac systems. The electrode physics works by establishing an electrical contact between the patient and the apparatus used to monitor activities.

Types of Electrodes in Electrotherapy

Electrodes can be divided into two broad types based on their specifications and usage.

  • Electrode types based on specifications

    • Reusable disc electrodes
    • Saline based electrodes
    • Disposable electrodes
    • Headband electrodes
  • Electrode types based on usage

    • ECG electrodes
    • Blood gas electrodes
    • EEG electrodes
    • Defibrillator electrodes

They can further be subdivided into Foetal Scalp Electrodes, Electrosurgical Electrodes, TENS Electrodes, pH Electrodes, Nasopharyngeal Electrodes, Pacemaker Electrodes, and Ion-selective Electrodes.
