The current is delivered through electrodes on the skin and “drowns out” pain signals along the nerves. Some types of current also improve blood circulation in the area. Electrotherapy for pain is a quick, painless treatment that is often done before exercises to make it easier to move. ## What to expect Kaloyan places the electrodes around the painful area and chooses the type of current according to the problem. With TENS (transcutaneous electrical nerve stimulation) you feel a rhythmic tingling or tapping. With interferential current you feel a light vibration deeper in. The device also works with other types of current, for example diadynamic and galvanic. Kaloyan turns up the intensity until the sensation is clear but pleasant. During the treatment you lie or sit comfortably. After the session the pain often eases for a few hours, so it’s a good time to do your exercises. On its own, electrotherapy doesn’t remove the cause of the pain. It helps while kinesitherapy (exercise and manual therapy) works on the cause. A course is usually 4–8 sessions. ## What it helps with - Lower back and neck pain - Sciatica and other nerve pain (neuralgia) - Joint pain, for example in the knee or shoulder - Pain after an injury or operation - Muscle spasms and tightness ## Who it’s for - Pain stops you doing your exercises. - You have chronic pain and want relief without increasing your medication. - You are recovering from an injury and want to combine the treatment with exercises. ## When it isn’t suitable - You have a pacemaker or another implanted electronic device. - You are pregnant, if the area is the abdomen or lower back. - You have a blood clot (thrombosis) in the area. - You have a wound, a skin condition or reduced skin sensation under the electrodes. - You have cancer in the area. - If you have a metal implant in the area, tell Kaloyan.

No. You feel tingling, tapping or vibration, which should be pleasant. If it becomes unpleasant, Kaloyan lowers the intensity. ### What is the difference between electrotherapy and electrical muscle stimulation? Electrotherapy uses currents that mainly reduce pain. Electrical muscle stimulation makes the muscle contract and is used to strengthen a weak muscle. ### How long does the effect last? Relief after one session usually lasts a few hours. With a series of sessions, together with exercises, the pain eases for longer. ### Can I have electrotherapy alone, without exercises? You can, but the effect will be shorter. Electrotherapy relieves pain, while exercises work on the cause, so Kaloyan usually combines them. ## More in Physiotherapy [All services in Physiotherapy](https://kainezitherapy.com/en/services/physiotherapy/) - [TECAR therapy](https://kainezitherapy.com/en/services/physiotherapy/tecar-therapy/) · 20 min · €25.00 · TECAR therapy in Sofia: radiofrequency energy that warms tissue from the inside and helps with back, joint and tendon pain and with recovery after injury. - [Electrical muscle stimulation (EMS)](https://kainezitherapy.com/en/services/physiotherapy/electrostimulation/) · 15 min · €25.00 · Electrical muscle stimulation (EMS): a current that makes a weak muscle contract when it can’t on its own, for example after surgery or immobilisation. - [Ultrasound therapy](https://kainezitherapy.com/en/services/physiotherapy/ultrasound-therapy/) · 15 min · €25.00 · Ultrasound therapy for tendon, ligament and joint pain: a short, painless treatment that targets the exact spot that hurts. - [Infrared therapy](https://kainezitherapy.com/en/services/physiotherapy/infrared-therapy/) · 20 min · €25.00 · Infrared therapy with a heat lamp: dry, pleasant warmth that relaxes tight muscles and eases stiffness before or after a massage or exercises. - [Combined physiotherapy](https://kainezitherapy.com/en/services/physiotherapy/combined-physiotherapy/) · 30 min · €25.00 · Combined physiotherapy: several device treatments in one visit, with Kaloyan choosing the physiotherapy devices to suit your problem. ## Want to improve your health?
