2. HOW DOES ELECTROSTIMULATION WORK?

Electrostimulation involves stimulating nerve fibres by electrical impulses transmitted by electrodes. The

electrical impulses produced by Compex stimulators are high-quality impulses that are safe, comfortable

and effective and stimulate various types of nerve fibres:

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

2. Certain types of sensitive nerve fibres to obtain analgesic effects 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 fibres

in the form of an electrical signal. This signal is then sent to muscle fibres, which contract. The principle

of electrostimulation correctly reproduces the process involved in a voluntary contraction. The stimulator

sends an electrical impulse to nerve fibres to excite them. This excitation is then transmitted to muscle

fibres and results in a 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 workout, depending on the muscle fibre. Various types

of muscle fibres can be identified depending on their respective contraction speeds: slow, intermediate

and rapid fibres. A sprinter clearly has more rapid fibres and a marathon runner has more slow fibres.

With good knowledge of human physiology and perfect control of stimulation settings in the various

programmes, muscular workout can be very accurately directed to achieve the desired objective

(muscular strengthening, increased blood circulation, firming, etc.).

03

EN

2. STIMULATION OF SENSORY NERVES

Electrical impulses can also excite sensory nerve fibres to obtain analgesic effects or pain relief.

Stimulating tactile sensory nerve fibres blocks pain being transmitted to the nervous system. Stimulating

another type of sensory fibre 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.

Note: Do not use pain relief programmes for an extended period without medical advice.

BENEFITS OF ELECTROSTIMULATION

Electrostimulation is a very effective method for making muscles work:

• with a significant improvement in various muscle qualities

• with no cardiovascular or mental fatigue

• with limited stress exercised on joints and tendons. Electrostimulation thereby enables more muscular

workout than voluntary activity.

For optimum results, Compex recommends supplementing your electrostimulation sessions with other

exercise, such as:

• regular physical exercise

• balanced and healthy diet

• balanced life style

3. HOW DOES MI TECHNOLOGY WORK

(MUSCLE INTELLIGENCE)?

N.B.: The activation/deactivation of MI functions is performed via the Settings menu

MI-SCAN

Just before starting a workout 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, at the start of the programme, a short test sequence during which measurements are

taken.

At the end of the test, intensities must be increased to start the programme.

MI-TENS

The MI-tens function limits unwanted muscle contractions in painful areas.

With each intensity increase, a test phase occurs and if a muscular contraction is detected, the device

automatically reduces the intensity of the stimulation.

This function is only accessible in the TENS, Epicondylitis and Tendinitis programmes.

MI-RANGE

The MI-range function allows the user to select the ideal level of stimulation intensity for recovery, massage,

capillarisation or even muscle pain programmes.

At the beginning of the programme, the device prompts the user to increase stimulation intensity. During this

increase, the device analyses the response of each stimulated muscle, and deduces their optimal level. As

soon as a muscle reaches its optimal level, the related channel is automatically deselected and the stimulation

intensity cannot be increased. To recover control, simply re-select the channel in question and raise or lower

the stimulation intensities.

MI-AUTORANGE

The MI-autorange function pursues the same objective as MI-range except that in this case everything is

done automatically.

At the beginning of the programme, a single press of the up key of the multifunction pad allows the device to

automatically increase the stimulation intensities until it detects the ideal level of intensity. Pressing the down

key of the multifunction pad cancels the MI-autorange function. The device then goes into manual mode and

intensities must be managed by the user.

05

EN

MI-ACTION

The MI-action function allows you an electro-induced contraction to be initiated by means of a voluntary

action. Thus the electro-induced contraction is perfectly controlled, the workout becomes more comfortable,

more thorough and more complete.

At the end of each active rest phase the remote control emits a beep. From this point the start of voluntary

contraction is possible. If no voluntary contraction has occurred after a certain period of time, the device will

automatically pause.

This work mode is available only for programmes inducing powerful muscle contractions.

N.B.: To function properly, the MI-action function needs good muscle twitches during the active rest phase.

If they are not significant enough, the device emits beeps and a + sign appears on the channels. Similarly, in

order to render these twitches possible, it is imperative that muscles be well relaxed during the rest phase.

At the end of each contraction phase, it is necessary to ensure that you return to a position allowing for best

muscle relaxation.

The table below shows which functions are available with each device.

The cycle logic refers to the workload performed by electrostimulation. And just like a normal workout,

one has to to start with an amount of work then increase it over the course of the cycles. Thus, it is

recommended starting with the 1st cycle and going on to the next level when the cycle is finished,

normally after 4 to 6 weeks of stimulation based on 3 sessions per week. It is also important to have

reached significant stimulation intensities in sessions before going on to another cycle.

In the case of transmitters whose maximum output power is not shown in the table above, the recommended spacing of d in

metres (m) can be calculated using the appropriate equation for the transmitter frequency, where P is the maximum output power

of the transmitter in watts (W) as set by the transmitter manufacturer

NOTE 1 At 80 MHz and at 800 MHz ,the spacing for high frequency amplitude is applied.

NOTE 2 These guidelines may not be appropriate for some situations. Electromagnetic wave propagation is modified by absorption

and reflection due to buildings, objects and persons.
