Information on Electrical Stimulation

Which electrostimulation device is best suited for which application?

Electrotherapy devices are classified according to the type of current and their intended use.

TENS – Pain Management

Transcutaneous electrical nerve stimulation for acute and chronic conditions: back pain, osteoarthritis, neuropathic pain, labor pain. Mechanism of action: activation of pain inhibition via A-beta fibers (gate control theory) and the body’s own release of endorphins. Frequency range typically 2–150 Hz. Many TENS devices are MiGeL-listed and, when medically indicated, are covered by basic health insurance (KVG).

EMS – Muscle Building

Electrical muscle stimulation for and strengthening in athletes, rehabilitation patients, and body sculpting. Frequencies of 30–80 Hz for and hypertrophy training. Popular in sports physiotherapy and competitive sports.

NMES – Neuromuscular Rehabilitation

Restoration of muscle function following surgery, in cases of paralysis, or muscle atrophy. This treatment is prescribed by a doctor and closely monitored by a therapist.

Iontophoresis

Transdermal delivery of active ingredients (e.g., for hyperhidrosis, tendinitis) using direct current—an effective complement to manual therapy.

Medium- and high-frequency therapy

Deep-tissue treatment for chronic pain syndromes and muscle tension, using either interference current or stereodynamic current.

What kind of electrodes do I need?

Self-adhesive gel electrodes (e.g., Chattanooga Durastick) are standard—available in 5×5 cm small muscle groups), 5×9 cm 10×5 cm larger areas). Lifespan: 15–30 uses, depending on skin condition and cleaning.

Are electrical stimulation devices listed in the MiGeL?

Yes. Many TENS devices are listed in the MiGeL and can be covered by basic health insurance if there is a medical indication. You can find the MiGeL number listed directly with the product.

How much does a professional EMS/TENS device cost?

Entry-level devices start at CHF 200. Professional 4-channel devices for range from CHF 500 to CHF 1,500. Stationary multifunctional systems (e.g., Chattanooga Intelect) cost up to CHF 3,500.
