Electro Stimulation Glossary

Electro stimulation was developed over 40 years ago, and has its own specific terminology. Here are a few key terms:


  • LACTIC ACID: Acid produced by muscular effort Muscular pain may occur when excessive quantities of lactic acid accumulate in the body.
  • AMPLITUDE: Intensity of stimulation.
  • ANALGESIC: For transcutaneous electrical nerve stimulation pain relief
  • SIMULTANEOUS ASSOCIATION OF DIFFERENT CURRENTS: This feature allows you to carry out different applications simultaneously. For example, you can use a single analgesic muscular program or two complementary analgesic programs.


  • BIOFEEDBACK: Retrospective review of muscular activity via electromyographic records.
  • BURST: Stimulation with bursts of low frequency pulses (80 Hz internal frequency and 1-5 Hz external frequency). This is most often used for endorphine-release analgesia.


  • “Y” CABLE (or SPLITTER): Electrode cable capable of doubling the quantity of electrodes.
  • CAPILLARY: Very thin blood vessel (see capillarisation programs)
  • SYMMETRIC RECTANGULAR COMPENSATING CURRENT: Used very commonly in muscle stimulation, this type of current does not result in oppositely polarized electrodes. This means that it can be used without fear of burns, even when metal objects are present in the body (pins, IUDs, etc.).
  • ASYMMETRIC RECTANGULAR COMPENSATING CURRENT: Used primarily in analgesic stimulation, the electrodes have opposite polarity (red positive and black negative). This means that it also can be used without fear of burns, even when metal objects are present in the body (pins, IUDs, etc.).


  • DENERVATED (MUSCLE): A muscle is denervated when all or part of its constituent fibres are separated from the nerve motor and the motor plate cannot function. The treatment for denervated zones must be carried out with stimulators equipped with specific programs (see the PRO section).
  • MODULATED PULSE DURATION: Duration of each pulse varies for a certain time.


  • ENDORPHINIC: Substance (peptide) produced by the brain that acts as a natural analgesic (for pain relief).
  • MOTOSTIMULATOR: Used for muscle stimulation and occupational therapy, sports and fitness.


  • MUSCLE FIBRES: Muscles are composed of slow twitch and fast twitch fibres. Slow twitch muscle fibres are primarily used in endurance sports, while fast twitch muscle fibres are used in sports requiring explosive movements.
    Number of electrical pulses per second. Expressed in hertz (Hz).
    A frequency of 10 Hz means that the muscle receives 10 electrical pulses per second.
    Low-frequency stimulation (1-10 Hz) is most commonly used to warm muscles and in rehabilitation, relaxation and capillarisation programs. This stimulation is designed to produce muscle vibrations but not contractions. These programs improve blood circulation, which in turn promotes the elimination of toxins and increases oxygen levels and muscular metabolism.
    For endurance programs, the average frequency falls between 15-30 Hz. Stimulation intensity must be high enough to produce visible muscle contractions. Endurance training consists of long sessions of submaximal effort that stimulate slow twitch muscle fibres and increase aerobic capacity.
    High frequency (50 to 120 Hz) stimulation is reserved for power training sessions. This frequency ensures optimal muscle contractions. These programs increase maximum force capacity and muscle mass. Three power training sessions are offered to correspond to different goals: maximum force, resistance force and explosive force.
  • MODULATED FREQUENCY: Automatic alternation of the frequency over a defined period of time.


  • GALVANIC: Galvanic current is a continuous polarized current used primarily for ionization.


  • HYPERTROPHY: Increase in muscle volume.
  • HYPOTROPHY: Decrease in muscle size.


  • IMPULSE: Each impulse varies according to a specific duration, called an impulse duration. This makes it possible to regulate the quantity of energy transmitted to the muscle. Short impulse durations are typically used on small muscle groups, while longer impulse durations are applied to larger muscle groups.


  • PULSE WIDTH: Duration of the phase of each individual impulse.
  • ADIPOCYTES: Cells that are specialized in storing fat (triglycerides) in their cytoplasm.


  • MICRO CURRENT: Very low intensity current that mimics electrical cellular currents, used in anti-edematous (for edema) and anti-inflammatory treatments.
  • MODULATION: To counteract the phenomena of habituation, particularly for analgesic stimulations, modulations can be used to automatically and cyclically vary current parameters.
  • ASCENDING SLOPE: This describes the time required to build up the current. For your comfort, we recommend that you gradually build up to the required intensity.


  • OBSERVANCE: This is a measurement of usage time or the dose of current received. This function is particularly useful for doctors and physiotherapists who want to oversee their patients’ follow through at home.


  • ACTIVE RECOVERY: This type of muscular stimulation allows you to prevent the build-up of toxins by offering vascularising stimulation between each contraction.
  • ACTIVE REST: The muscle is stimulated during the rest period between muscular contractions.


  • SEQUENCE Part of a program.
  • LYMPHATIC SYSTEM: Series of vessels that transport lymph, which in turn carries tissue waste products to the veins.
  • VENOUS SYSTEM: System of veins that pump blood from tissues to the heart.


  • TOXINS: Toxic substances in the organism.


  • URO: Category of programs used to treat incontinence and for perineal rehabilitation. These programs often require the use of vaginal or anal probes.


  • INDEPENDENT CHANNELS: This technical characteristic allows you to set each channel to a different intensity.
  • SIMULTANEOUS CHANNELS: Stimulated muscles contract simultaneously.
  • ALTERNATING CHANNELS: Stimulated muscles contract in reciprocal alternation.
  • SYNCHRONIZED CHANNELS: Stimulated muscles are recruited alternately with a delay.
