Electrostimulation involves stimulating nerve bres by electrical impulses transmitted by electrodes. The electrical impulses produced by Compex stimulators are high-quality impulses that are safe, comfortable and eective and stimulate various types of nerve bres:

1. Motor nerves to stimulate a muscular response, referred to as electrical muscle stimulation (EMS).

2. Certain types of sensitive nerve bres to obtain analgesic eects or pain relief.

1. STIMULATION OF MOTOR NERVES (EMS)

With voluntary activity, the brain orders muscles to contract and a command is then sent to nerve bres in the form of an electrical signal. This signal is then sent to muscle bres, which contract. The principle of electrostimulation accurately reproduces the process involved in a voluntary contraction. The stimulator sends an electrical impulse to nerve bres to excite them. This excitation is then transmitted to muscle bres and results in a basic mechanical response (= a twitch). This is the basic requirement for muscular contraction. The muscular response is to all intents and purposes identical to the muscular work controlled by the brain. In other words, the muscle does not distinguish between a command sent by the brain or the stimulator. Programme settings (number of impulses per second, duration of contraction, rest time, total programme duration) subject the muscle to various types of work, depending on the muscle bre. Various types of muscle bres can be identied according to their respective contraction speeds: slow, intermediate and fast bres. A sprinter clearly has more fast bres and a marathon runner has more slow bres. With good knowledge of human physiology and full control of stimulation settings of the various programmes, muscular work can be specically pinpointed to achieve the desired objective (muscular strengthening, increased blood circulation, rming, etc.).04

Electrical impulses can also excite sensory nerve bres to obtain analgesic eects or pain relief. Stimulating tactile sensory nerve bres blocks pain being transmitted to the nervous system. Stimulating another type of sensory bre increases the production of endorphins and therefore reduces pain. With pain relief programmes, electrostimulation can be used to treat acute or chronic localised pain and muscle pain. Caution: Do not use pain relief programmes for an extended period without medical advice.

BENEFITS OF ELECTROSTIMULATION

Electrostimulation is a very eective method for making muscles work:

• With a signicant improvement in various muscular qualities

• With no cardiovascular or mental fatigue

• With limited stress exerted on joints and tendons. Electrostimulation thereby enables more muscular work than voluntary activity. For optimum results, Compex recommends supplementing your electrostimulation sessions with other commitments, such as:

• Regular physical exercise

• A balanced and healthy diet

• A balanced lifestyle05

TECHNOLOGY WORK? To access MI functions the MI-sensor cable must be connected to the stimulator. MI-SCAN Just before starting a work session, the MI-scan function probes the chosen muscle group and automatically adjusts the stimulator settings to the excitability of this area of the body, depending on your physiology. This function results in a short test sequence at the start of the programme, during which measurements are taken. At the end of the test, the intensity has to be increased to start the programme. MI-TENS The MI-tens function limits unwanted muscle contractions in painful areas. With each intensity increase applied by the user, a test phase occurs, and if a muscular contraction is detected, the device automatically reduces the intensity of the stimulation. MI-RANGE The MI-range function indicates the ideal range for adjusting stimulation intensity, to be followed in the following programmes: recovery, massage, capillarisation or even muscle pain. When the device has detected the ideal intensity range, check mark will appear on the screen. For optimum work, intensity should be kept within this range.06

BATTERY LEVEL AND CHARGING

Battery performance depends on the programme and the stimulation intensity applied. It is strongly recommended to fully charge the battery before its rst use to improve its performance and life span. Always use the charger supplied by Compex to recharge the battery. If the device is not going to be used for over 3 months, ensure that the battery is fully charged. If the device is not going to be used for over 6 months, ensure that the battery is fully charged and remove it from the stimulator. Switch the stimulator o before removing the battery. BATTERY LEVEL The battery charge level is shown by a battery icon in the bottom left of the screen. The battery icon ashes when the battery is completely at. The device can then no longer be used. Recharge it immediately.15

RECHARGING Remove all stimulation cables from the stimulator before recharging it. Connect the charger to a wall socket and connect the stimulator by sliding the red cover to the right to reveal the charger connector.

The charging menu shown below appears automatically. The charging duration is displayed on the screen. As soon as charging is complete, the battery ashes. Disconnect the charger: the stimulator will switch o automatically.16

ELECTRODE FAULT The device emits a tone and alternately displays the pair of electrodes symbol and an arrow pointing towards the channel on which a problem has been detected. In the above example, the stimulator has detected an error on channel 1. Check that the electrodes are connected to this channel. If electrodes are old, worn and/or if the contact is poor: try using new electrodes. Try using the stimulation cable on a dierent channel. If the cable is still faulty, replace it (www.compexstore.com). STIMULATION DOES NOT PRODUCE THE USUAL SENSATION Check that all settings are correct and check electrodes are properly positioned. Change the position of the electrodes slightly.

STIMULATION CAUSES DISCOMFORT

Electrodes lose their adhesive capacity and no longer provide suitable contact with skin. Electrodes are worn and must be replaced. Change the position of the electrodes slightly.17

When an error screen is displayed during use, note the error number (in the example, the error number is 1/0/0) and contact the Compex-approved customer service centre.

THE BATTERY IS VERY FLAT

If the following screen appears, switch the device o and connect the charger. If a battery is very at, a recovery cycle will start, lasting 2 minutes.18

When this has nished, if the battery is working properly, it will start charging; in this case, it is strongly recommended to perform a charge/discharge cycle for the battery by pressing on the channel 4 button to launch this cycle, which may take up to 12 hours. If, however, it proves to be faulty, the following screen appears and the battery must be replaced.19
