What is Electric Muscle Stimulation? How Does it work?

Electrostimulation is not a miraculous technique, it is very simple and precisely reproduces the processes that occur when our brain orders muscles to contract. It respects how our body works.

When we decide to contract a muscle, our brain sends a command in the form of an electrical signal to the nerve fibres. This signal is then sent to muscle fibres, which are excited and contract. In the case of electrostimulation, excitation occurs directly on the motor nerve using electrical impulses.

Our aim is to help

IMPROVE THE SPORTING PERFORMANCES OF ATHLETES AND RELIEVE MUSCLE PAIN

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.

The electrical impulses produced by Compex (globally known as Optimal Impulses
– “an International Scientific Consensus”) are perfectly controlled to guarantee effectiveness, safety and comfort in use.

Stimulation can occur

in two types of nerve fibres:

1. Stimulation of the motor nerves 

(Efferent Nerve Fibres) to stimulate a muscular response, 
referred to as Electrical Muscle Stimulation (EMS). 

This type of stimulation will cause muscle twitches or muscle contractions, and it can be targeted to assist with recovery, with the recruitment of slow or fast twitch muscle fibres based on your goals, and targeted to assist with muscular pain. The physiological characteristics of the twitches and the contractions are equal to the ones caused by a voluntary activity commanded by the brain.

2. Stimulation of sensory nerve fibres

(Afferent Nerve Fibres)  to obtain analgesic effects or pain relief; 
referred to as Transcutaneous Electric Nerve Stimulation (TENS). 

Stimulating tactile sensory nerve fibres blocks pain being transmitted to the nervous system, acute and/or chronic localized pain and muscular pain. With pain relief programmes, electrostimulation can be used to treat acute or chronic localised pain and muscle pain.

It is very important to understand the difference between EMS (or NMES) and TENS. Many people have been in physical therapy and may have had an experience with TENS and EMS devices, but were not educated on the difference between these types of modalities.

How Does it Work?

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.).
