In electrotherapy, what is the primary function of electrodes?

• A. To measure electric current
• B. To apply heat to the skin
• C. To direct electric current to the skin
• D. To contain chemicals

Answer: (C)

The primary function of electrodes in electrotherapy is to direct electric current to the skin. Electrodes serve as conductive pads that facilitate the flow of electricity from an electrotherapy machine to the skin's surface. When placed on the skin, they help in delivering therapeutic electrical currents to targeted areas, which can aid in pain relief, muscle stimulation, or tissue repair. In electrotherapy, the effectiveness of the treatment heavily relies on the correct placement and use of electrodes to ensure that the current is accurately delivered to the desired location. This targeted application of electric current is crucial for achieving the intended therapeutic effects. While other options may reference related concepts—such as measuring electric current or applying heat—these actions are not the primary purpose of electrodes within the context of electrotherapy. The use of electrodes is specifically focused on ensuring that electric currents are effectively directed to the skin for therapeutic benefits.
