Electostimulation consists of stimulating your muscle by sending small electrical impulses with the aims of treatment, relaxation and strengthening. The electric pulse varies (in intensity and duration) and causes a physiological contraction without soliciting the central nervous system. The electrodes are then positioned on the area you want to work: ABS, thighs, chest, buttocks.
There are two types of electrotherapy: TENS (Transcutaneous Electrical Nerve Stimulation) and EMS (Electrical Muscle Stimulation). The first relieves pain by stimulating the secretion of endorphins while the second targets muscles through contraction. EMS’ main objective is to strengthen the muscle either in addition to physical exercise or as part of muscle rehabilitation.
“The acronym TENS stands for Transcutaneous Electric Nerve Stimulation. Electrostimulation goes back to ancient Egypt (about 2500 BC). Stone tablets have been discovered engraved with the description of a technique for pain relief that consisted of using the shock produced by electric eels. Similarly, in the time of Socrates this technique was used to relieve arthritis pain and headaches. However, TENS really took off only after the Revolution when Italian physicist Luigi Galvani – the verb “”galvanize”” comes from Galvani – scientifically demonstrated for the first time the muscle activation by the current (1791).

It is not until 1965 that electrostimulation was recognized as a treatment and became systematized.”
Nerve fiber electrostimulation produces endogenous analgesics (called analgesic electrotherapy). These are pain-killing substances generated naturally by the body when we need it. They are mainly endorphins (neurotransmitters), which act on opioid receptors when secreted. Opioid receptors control our response to pain, stress and emotions.

Put simply, electrostimulation can block the transmission of pain information to the brain through the release of pain-killing substances. The feeling of pain will gradually disappear. By choosing the exact current and intensity you can perfectly target the analgesic action on the painful area based on the injury. In short, electrostimulation is undeniably effective.
Bluetens uses 2 different techniques to reduce pain: the first technique has been conceived for an immediate effect and the second one for a slower effect that persists in time. Without knowing it, we all instinctively use the first one: when we bang our elbow for instance we immediately rub the painful area. In this way, we are transmitting not only a pain message to our brain, but we are also sending out a “touch” message.

This message, being quicker, will eventually block the “pain” message. This is exactly the natural technique we use in a more targeted and efficient way. The second technique stimulates endorphin production. Endorphin is a natural hormone inducing analgesic effects that will quickly bring a well-being sensation to the painful area. Once endorphins have been secreted, they will continue to work even after the program ended.
Everyone can use Electrostimulation since its uses range from simple muscle relaxation to intense muscle strengthening as well as treatment. Regardless of your athletic abilities, there are many situations in which electrostimulation can be used. Some examples are:

Relieving muscle pains and strains or postoperative pain. One program will cut the transmission of pain messages and help your body to resume normal activity more quickly. After a long day at work where your back has been submitted to awkward positions, a suitable programme will relax the sore areas. Following any physical exertion, another programme will help prevent aches and relax your muscles.

While practicing sport, there is a programme that will amplify the work done and will tone and strengthen your muscles. When suffering from certain illnesses such as dermatological issues or after surgery, it is best to seek the advice of a doctor before using Bluetens as you will need to take special care.
Take the example of a typical muscle strengthening session after an injury to the right calf. Ensure you are sitting with your back straight, parallel legs and ankles placed on the floor.
Set up your Bluetens, cables and electrodes. Choose the area of the body (calf), select the ‘Care’ action and click “GO!”. When clicking a program within the list, you will have access to its description. Make your selection and click “GO!”
Next place the electrodes in the right place by following the anatomical diagram. The application now prompts you to turn on your Bluetens, after synchronizing for few seconds the session will begin.

Now relax and let Bluetens do its work!
The number of times the electrodes can be used depends on the condition of your skin (hair, skin type, etc.), where they are placed on your body and the type of treatment or care applied. Regularly check the state of your electrodes, when the gel no longer adheres to your skin properly it is a sign that they need changing.

Bluepacks are available on our web site (LINK – BLUE PACK). These are sets of 12 electrodes (3 packs of 4) identical to those which came with your Bluetens. Use them to replace your worn electrodes.
For reasons of hygiene and to keep your electrodes in good condition we advise you not to share electrodes.
Connection is automatic, as soon as you will launch the selected program. You won’t need to adjust your settings each time. You should only activate your Smartphone’s bluetooth function and voila!
Bluetens runs on a lithium-ion battery and is easy to recharge using a micro-USB cable. Charging takes one hour and it provides you with 4-5 hours of treatment.
The intensity setting of the Bluetens depends on the chosen programme as well as the area being treated. We recommend you to start with the lowest intensity offered by the device and increase it to your desired level while remaining in your comfort zone.
If your goal is to control pain, the effect may be felt immediately depending on the type of pain and the treated area. You will notice a feeling of improvement as the sessions continue with the maximum benefit reached after 3 weeks of treatment.
Although this will vary depending on your goal, when used regularly you will see an improvement in your muscle tone and in your general fitness level as early as after 3 to 4 week.
“People who have a pacemaker or who are epilepsy-prone must not use Bluetens. Pregnant women are also strongly discouraged from using it, as well as people suffering from hernisa or eventrations.

People with cardiac illness must avoid areas around the heart. You should not use Bluetens if you have:
– Implants or metal prosthetics in your body.
– Any heart irregularities or heart disease.
– Diabetes (loss of sense of touch)
– Serious blood circulation disorders of the lower limbs
If you have any doubt, please consult a doctor.
Please read the safety instructions in our online manual to ensure the device’s safest possible use.

– Do not use Bluetens in water or in a humid environment (sauna, balneotherapy or hammam, etc.).

– You must not place the electrodes on the carotid sinus (front of the neck), transcranial (through the head) or transthoracic (through the rib cage) regions. Please follow the advice on where to place the electrodes to avoid making mistakes. Advices have been drawn up by health professionals and correspond to the areas of the body where Bluetens will be most effective.

– Use only the electrode cables provided by Bluetens.

– Never connect the electrode cables to an external power source as this carries the risk of producing an electric shock.

– Do not use any damaged or defective electrode cables.

– Always use the USB cable provided by Bluetens to charge the device.

– Never use Bluetens or the USB cable if damaged.

– Keep the Bluetens and its accessories out of reach of children.

– Do not allow foreign objects (soil, water, metal, etc.) to enter the Bluetens.

– Do not use Bluetens while driving.

– Never recharge Bluetens while it is in use. There is a safety device (slider) that prevents it from being used and recharged at the same time. Do not remove this for any reason; it is there for added protection.

If you have any doubt, please consult a doctor.

Bluetens remains accessible to many people because its brain (your smartphone) is separated from its engine (the Bluetens). In other words we use the power of your smartphone combined with an app to control the Bluetens allowing us to keep the price low.
Our competitors on the other hand must equip their devices with a screen and internal software in order to offer the same functions as the Bluetens. This explains the difference in prices (up to double or even triple our price), without our competitors being as evolutionary as Bluetens.
