Simple and quick to fit


Place the Tensi+ over your ankle. The lower electrode should be placed just below and behind the medial malleolus (inner side of the ankle). 

Starting up the device

Press and hold down the On/Off button. The LEDs light up, and you will hear a soft, long beep. Gradually increase the intensity of the treatment by pressing and holding down the button +, until you feel a slight. 

Treatment for 20 min

Treatment with Tensi+ has started. It switches off automatically after only 20 minutes of treatment.

A simple treatment spread over time

Week 1 :

First use of Tensi +, every day for 20 minutes.

Week 6 :

Perception of a reduction in the symptoms and the initial effects on regaining bladder control.

Week 12 :

Significant improvement in your overactive bladder symptoms. The initial phase of treatment is then finished.

Following weeks :

Maintain the use of the Tensi+ to sustain the effects of improvement.

Contraindications – Do not use the device

  • If you have a pacemaker, defibrillator, or any other electronic implant, as this could cause an electric shock, interference, burns, or cause your pacemaker to malfunc-tion;  
  • if you have a metal implant near the stimulated area, as this could result in burns or cause interference with Tensi+;
  • if you have ankle joint problems, swollen ankles or a dermatological condition or damaged skin in the area where the electrodes are to be placed; if you are pregnant;
  • if you have a cognitive impairment.

If in doubt, ask your doctor.

Aids to support you

Use of the Tensi+

Do you have any questions?

Yes, numerous clinical trials attest the efficacy of the TENS technique to treat overactive bladder. For more information, see the sources below.  

Each LED represents a range of intensity levels. The intensity varies progressively between 2 LEDS by small degrees of 0.5 mA, (short and discrete beeps), as long as the user keeps pressing the (+) or (-) buttons.

Connect Tensi+ using the USB cable supplied to a powered USB port or to your computer, or via a mains adapter. We recommend charging Tensi+ for at least 8h before the first use. The battery charging LED (at the top left of the Tensi+) then lights up. This LED goes out once the Tensi+ is fully charged.

Make sure there is sufficient gel on each electrode and/or adjust the position of the bracelet on your ankle. It is sometimes possible not to feel any tingling, this does not mean that your treatment will not work. You can observe your big toe: if it is retracted slightly downwards and vibrates, then Tensi+ is well positioned on the path of the posterior tibial nerve. Discuss this with the health professional who prescribed Tensi+ for you. 

If your Tensi+ does not increase above the levels of 3 or 4 LEDS or more, this means that it has reached its limit of 50V depending on the resistance of your skin. The skin does in fact have the ability to oppose the circulation of electrical current. The more conductive your skin is, the more your device can increase in intensity. What you need to look for is the perception of the sensation of tingling under the foot. It is not absolutely vital to increase the intensity once the tingling is felt.

This means that the device has disconnected from your skin for more than one second. Make sure that there is enough gel under each electrode to facilitate conduction, and move the device slightly to find the posterior tibial nerve.

Yes, this is the phenomenon of habituation of our nervous system which very quickly gets used to nerve stimulation. Don’t worry, if it was working at the very start, then it is working. When you next use it, try to slightly increase the intensity, but be aware that this phenomenon varies every day.
