Russian Stimulation, also known as Burst Mode Alternating Current (BMAC), is when low frequency current is delivered in a pulse or burst, which stimulates the nerves and triggers a reaction, much like motor response.
Interferential Current Therapy is used to relieve pain and speed up the process of self-healing. The current is delivered in high frequency signals that penetrate through the skin into deep muscle tissue.
Pre-Modulated Current Therapy (Premod) is similar to Interferential current therapy, but uses a single channel to mix the frequencies prior to the delivery of the current through an electrode, using only two electrodes as opposed to four. This allows the treatment area to be smaller and is beneficial when treating areas that are not big enough for four electrodes like an elbow or ankle.
