Electrical stimulation (E-Stim) may be used clinically for multiple reasons. Those reasons may be for analgesia or for the production of a muscle contraction.
Electrons are negatively charged particles with a very small mass. When these electrons move, it is termed electrical current. These electrons travel from a high potential to a low potential. E-Stim uses this technology to excite nervous or muscle tissues.
E-Stim units have the capability or producing multiple types of currents. Interferential (IFC) is the commonly used mode for analgesia as mentioned earlier; whereas Russian, is used for muscle reeducation. Russian can help patients with neurological deficits by conducting an action potential. This action potential is a nervous signal that activates a muscle contraction. This signal is produced by the instrument and transmitted through the electrodes directly on the desired muscle.
Indications for use:
- Muscle reeducation
- Pain relief
- Muscle pump contractions
- Retardation of atrophy
- Muscle strengthening
- Increasing range of motion
- Decreasing edema
- Tendon healing
- Ligament healing
