Here are some of the most frequently asked questions…
Kosi™ is a TENS device, which stands for Transcutaneous Electrical Nerve Stimulation. Kosi™ works by passing a tiny electrical current through two pads placed on nerve roots supplying sensory fibers to the uterus and/or lower back. The stimulation, once in place, inhibits pain signals from reaching the brain, causing the muscles in the uterine area to relax and produce a relaxing analgesic effect.
Absolutely! Kosi™ is a pain reliever for primary period pain (dysmenorrhoea). However, it may also assist to reduce secondary period discomfort caused by endometriosis, PCOS, fibroids, adenomyosis, or pelvic inflammatory disease.
