Electrotherapy is a therapeutic procedure that uses electrical impulses or currents to treat a variety of medical conditions and promote tissue healing. During electrotherapy, electrodes placed on the patient's body are connected to an electrical stimulator or device that generates specific electrical impulses. These pulses can vary in frequency, length and intensity, and each type of pulse can have a specific effect on the tissues and nervous system.
Electrotherapy is often used to treat pain, reduce muscle tension, promote muscle and tissue recovery after injury, and treat certain neurological and rehabilitation conditions. This method is often painless and non-invasive and is therefore widely used in physiotherapy and medical rehabilitation practices to provide an effective and safe therapeutic approach.
