The Science Behind the Relief
The RS-4i Plus combines Interferential Therapy (IFT) and Neuromuscular Electrical Stimulation (NMES) in a unique 35-minute treatment called Intersperse. Explore the mechanisms of action producing industry-leading results.
Interferential Therapy
Pain relief resulting from an enkephalin release.
Interferential Therapy (IFT) is used for pain relief and works by overlapping two slightly different high-frequency signals, for instance 5000 Hz and 5150 Hz. These signals intersect within the body to create an area of interference – a “sweet spot” where the therapeutic benefit is strongest.
This intersection of signals results in a new frequency – the beat frequency – which is able to recruit the maximum number of A-beta nerve fibers for treatment. These high-frequency signals also trigger the body’s production of enkephalins, short-chain peptides (endogenous opiates) that provide pain relief lasting about 1 hour.
Neuromuscular Electrical Stimulation
Muscle therapy resulting from contractions that act as a blood and lymphatic fluid pump.
Neuromuscular Electrical Stimulation (NMES) is used for muscle stimulation and causes lower motor neurons to fire. RS Medical uses an adjustable, custom square/asymmetrical spiked waveform with a frequency of 71 Hz that is able to activate both fast and slow-twitch muscle fibers.
Being able to stimulate a broader range of muscle fibers, especially large stabilizing muscles in the legs and the back, allows the RS-4i Plus to elicit a maximal muscle contraction – which expels metabolic waste and supplies a flow of oxygen and nutrient-rich blood to the muscles.
Intersperse
Pain relief resulting from combined hyper-stimulation of A-beta nerves and lower motor neurons that triggers an endorphin release.
Intersperse is a patented treatment session in the RS-4i Plus that intermixes premodulated IFT and NMES. During this session, pain relief signals are delivered during the relax period of muscle stimulation – giving the patient a repeating pattern of intermittent contraction, then pain relief, then contraction.
This unique intermixing of IFT pain treatment and NMES muscle therapy sends a sequence of signals up the neo and paleo spinothalamic tracts into the brain and provokes a beta-endorphin release. These are long-chain peptides (endogenous opiates) that provide pain relief lasting up to 8 hours.

Breaking Down an RS-4i Plus Treatment
Pain Relief
RS-4i Plus Intersperse treatments begin with 5 minutes of Interferential Therapy (IFT), where the transmission of pain signals to the brain are blocked by a high-frequency signal that hyper-stimulates A-beta nerve fibers. Treatment can help relieve acute musculoskeletal pain or relieve and manage chronic musculoskeletal pain.
Muscle Rehabilitation
After IFT knocks down the pain, the RS-4i Plus shifts to 5 minutes of Neuromuscular Electrical Stimulation (NMES). During this segment, the RS-4i Plus delivers a custom signal that causes the treated muscle to involuntarily contract, relaxing muscle spasms, preventing or slowing muscle atrophy, increasing circulation, and maintaining or increasing range of motion.
Intersperse
Intersperse is the third and most unique segment, which combines IFT and NMES. During this 25-minute treatment, pain relief signals are delivered during the relax period of muscle stimulation – giving the patient a repeating pattern of intermittent contraction, then pain relief, then contraction. This patented intermixing of treatments provokes a beta-endorphin release that provides pain relief up to 8 hours.
