Members of ICCMO routinely utilize Ultra Low Frequency (ULF)-TENS while finding the neuromuscular rest position by relaxing muscles.
The input is applied bilaterally to the Maxillary Division (Sensory) of the Trigeminal Nerve. The Sphenopalatine Ganglion is found in the Pterygopalatine fossa on the Maxillary Division of the trigeminal nerve.
Is it an excellent method of decreasing cerebrovascular Ischemia?

Abstract
Purpose: The parasympathetic effects of the sphenopalatine ganglion (SPG) on the cerebral vasculature provide a compelling rationale for its therapeutic application in cerebrovascular ischemia. In recent years, attempts have been made to stimulate the SPG to achieve beneficial effects on cerebral circulation.
Methods: This review synthesizes the available publications on SPG stimulation. It critically evaluates the evidence from preclinical studies and clinical trials to assess its potential as a treatment for acute cerebrovascular disorders and outlines aspects that still require more study.
Results: The medical literature provides consistent evidence of the significant effects of stimulating the SPG on cerebrovascular circulation. In addition, considerable evidence supports the therapeutic role of SPG stimulation in patients with cerebral ischemia.
Conclusion: Given the current understanding, future research could explore the potential of SPG stimulation as a non-reperfusion intervention to improve long-term outcomes for individuals with ischemic cerebrovascular conditions.

Abstract
The Sphenopalatine Ganglion (SPG) is known to play an integral role in the pathophysiology of a wide variety of orofacial pains involving the jaws, sinuses, eyes and the trigeminal autonomic cephalalgias. It supplies direct parasympathetic innervation to the trigeminal and facial nerves. Sympathetic innervation from the superior sympathetic chain passes thru the SPG to the trigeminal and facial nerves.This paper reviews relevant and significant literature on SPG Blocks and Neuromodulation published in peer reviewed medical and dental journals. Neuromuscular Dentistry employs ULF-TENS to relax musculature and simultaneously provide neuromodulation to the ganglion.Conclusion: The effects of ULF-TENS on the autonomic nervous system acts on the Limbic System and Hypothalamus (H-P-A) to address Axis II issues during neuromuscular dental procedures. It also directly affects the autonomic component of the trigeminal nerve involved in almost all headaches and migraines as well as the Myofascial and Joint disorders of TMD.
