Abstract: An orthotic device and method that reduces or eliminates the physical effects associated with movement disorders, such as Tourette's Syndrome, and temporomandibular joint (TMJ) disorders. Specifically, the device and method eliminates or substantially reduces the involuntary movements and premonitory urges associated with movement disorders without the need for medication or surgery. The device and method also eliminates or substantially reduces the pain, nerve stimulation and other effects associated with TMJ disorders, such as displaced articulated disks. The device includes a base portion and adjustable raised spacers that adjust the position of the mandible to relieve pressure exerted on the trigeminal nerve (the fifth cranial nerve or CN V), retrodiscal tissue, and other nerves due to improper TMJ alignment. The liberation of pressure and stimulation on the trigeminal nerve, retrodiscal tissue and other nerves eliminates the involuntary movements, pain and stimulation associated with these conditions.
