Description: DOCTOR-BACKED AND TESTED: Zok has been tested and proven by over 100 doctors in the USA ranging from neurological trauma center doctors to naturopathic doctors and M.D.’s to ensure Zok’s effectiveness and safety for their patients. INNOVATIVE RELIEF: Zok works by activating cranial nerve 5, 7, 9 and 10 inside the ear canal through light, pneumatic neurostimulation insufflation. Through scientifically calibrated pressure modulation from inside the device, Zok facilitates the precise sequenced flow and rate of stimulation inside the ear canal to signal the corresponding cranial nerves inside the brain stem, which are associated with near instantaneous equilibrium and relief.
