Born from a problem raised by French urologists, Stimuli Technology has been working since 2018 on the implementation of a device for the treatment of bladder hyperactivity by transcutaneous electrical neurostimulation (TENS).
Overactive bladder affects the lives of millions of people around the world
Under-diagnosed and under-treated, OAB can affect both men and women and can occur at any age. It is mainly manifested by a urinary urgency, a sudden and uncontrollable urge to urinate (urgency), generally associated with the manifestation of one or more of the following symptoms: frequent urges to urinate at any time of the day (pollakiuria), or night (nocturia), the urinary urgency can sometimes be followed by a urinary leakage (urge incontinence).
Studies have shown that around 15% of the world’s population has an overactive bladder, rising to 30% to 40% in the over 75s*. Despite this, only 1/3 of patients have ever sought treatment for these symptoms**. Today, there are solutions that can help relieve or control these symptoms, but most of them are invasive and/or have side effects.
Tensi+: a response adapted to a real need
Transcutaneous Electrical Nerve Stimulation, more commonly known as TENS, is a non-medicinal and non-invasive technique which consists of transmitting electrical impulses close to an innervated area via electrodes placed on the skin, to act on nerve transmission.
Developed in close collaboration with expert doctors, specialised referents on the subject of bladder hyperactivity*** , the Tensi+ medical device acts on the posterior tibial nerve, part of which is close to the nerve fibres controlling the bladder. Stimulation of this nerve modulates the messages transmitted between the bladder and the brain, improving the central neurological control of urination.
Placed on the skin at the level of the ankle, on the passage of the posterior tibial nerve, the 2 electrodes of the Tensi+ send electrical stimulations. Designed for home use by patients, the Tensi+, with its intuitive operation, offers a simple adjustment of the stimulation intensity to adjust to the comfort threshold of each person.
Easily transportable and discreet, Tensi+ offers a 20-minute treatment per day, with a reduction in symptoms from 6 weeks. A significant improvement is perceived after 12 weeks of treatment.
