[Update 9/15/19] Revisiting the PoNS, Portable Neuromodulation Stimulator Device, which stimulates the tongue, after listening to Robert J. Marks interview Dr. Yuri Danilov on the Mind Matters News podcast episode Accelerating Neuroplasticity-How Natural Brain Healing Can Be Accelerated Using Stimulation.
The device is already being used at clinics in Canada for treatment of chronic balance deficit due to mild-to-moderate traumatic brain injury, and is to be used in conjunction with physical therapy.
In clinical studies, the PoNS device coupled with targeted functional therapy induces cranial nerve noninvasive neuromodulation (CN-NINM). Therapy consists of targeted physical, occupational and cognitive exercises, based on the patient’s deficits. (The PoNS™ Device from Helius Medical)
