STIM Tech 4

The Stimtec 4 is a compact and versatile electrotherapy device offering four therapeutic modalities: Interferential Therapy (IFT), Russian Stimulation, TENS, and EMS. Designed for both pain management and muscle activation, it is widely recognized as one of the most effective and reliable devices used in physical therapy settings.

Therapeutic Modalities Included:

• EMS (Electrical Muscle Stimulation): For muscle activation and rehabilitation

• Russian Stimulation: For targeted muscle strengthening

• Interferential Therapy: For deep muscle and tissue pain relief

• TENS (Transcutaneous Electrical Nerve Stimulation): For nerve-related pain management

About Interferential Therapy (IFT)

Interferential Electrical Stimulation is a specialized method for delivering therapeutic frequencies deep into body tissues. The technology uses a fixed carrier frequency of 4,000 Hz combined with a second adjustable frequency ranging from 4,001 to 4,400 Hz.
When these frequencies intersect, they create a therapeutic current capable of penetrating deep into muscles and tissues while also acting on the surface. This results in enhanced analgesic effects and improved nerve-blocking responses for effective pain relief.

About Electrical Muscle Stimulation (EMS)

EMS works by sending electrical impulses through self-adhesive electrodes placed on the skin over specific muscles. These impulses activate the underlying nerves, causing the muscle to contract and relax—essentially simulating natural exercise.

Healthcare professionals commonly use EMS to:

• Prevent or reduce muscle atrophy following injury or surgery

• Improve blood circulation in targeted areas

• Increase range of motion

• Enhance muscle strength, tone, and endurance

EMS is also widely utilized by athletes and bodybuilders as a complementary tool for strength training. In fact, Olympic-level athletes have employed EMS for more than two decades to maximize performance and recovery.
