Cranial-Nerve Non-Invasive NeuromodulationCranial-nerve non-invasive neuromodulation was developed to improve neuroplasticity – the brain’s ability to reorganize and regain abilities – and thereby strengthen functional recovery. The approach was devised for use with rehabilitation training and physical therapy. Clinical trials have been carried out in patients who have mild to moderate traumatic brain injury or multiple sclerosis. (1 - 3) One such device delivers patterned sequences of electrical stimulation through a portable neurostimulator placed on the tongue. Typically patients are instructed to use the device at home during a training regimen. Developers explained they considered the tongue a promising interface to relay signals to the brain due to such factors as its neural pathways, and the conductivity of saliva. The signals are thought to help induce neuroplasticity. This potential treatment has been investigated to augment rehabilitation for balance deficits. (4-6)
