PAINSHIELD For Trigeminal Neuralgia

Trigeminal neuralgia (TN) is one of the most severe and progressive forms of chronic neuropathic pain. The latest scientific work has shown that the likely anatomic cause of the TN is a highly reversible tiny CNS lesion at the root entry zone of the trigeminal nerve measuring less than 0.5 cm3.

The presence of a discrete, highly eloquent and highly reversible CNS lesion presents a unique opportunity to test and measure the Neuroregenerative potential of therapeutic modalities that can be effectively delivered to the site of this pathology. Neuroregeneration refers to the regrowth or repair of nervous tissues or cell.


This novel approach of delivering LILF ultrasound allows for longer and more effective treatments. The Surface Acoustic Waves, unlike traditional ultrasound, are characterized by elliptical particle movement travelling with great efficiency across bony surfacesvii. When applied to a bony surface, such as the forehead, the LILF/ SAW will travel and reach the entire surface of the skull and be effectively and efficiently transmitted via the CSF to the CNS structures juxtaposed against the bony structures. Hence, the root entry zone of the trigeminal nerve as well as the entire length of all its branches are exposed to LILF/SAW which also travel along the bony surface inside the cranial nerve foramina.

The recurrence of pain in some patients, may be subsequent to the progress of the demyelinating illness deeper in brain or that the disease itself progressed beyond the capacity of our treatment modality to stop it.

In addition to the hypothesized neuroregenerative effects of the LILF/SAW, it may also bring the added advantage of a wide surface Phonophoresis effect and possibly a mechanical washout of accumulated pro-algesic substances in the nerve itself as well as the facial soft tissues. This would be caused by the mechanical effect of a 2 micron unidirectional mechanical pressure wave traveling through these tissues at 90kHz. In some of the cases described in this report, the Phonophoretic effect inherent to ultrasound also became evident when PainShield treatment was combined with compounded topical medicine crèmes containing ketamine, and various anti-epileptic drugs amongst othersviii.
