Book excerpt: Dr. Perri demonstrates how eye movements and patient-assisted postures can be used to correct vertebral subluxations, somatovisceral and viscerosomatic abnormalities. The text fully demonstrates the techniques and discusses the neurological pathways activated in the applications. He fully explains how visual fields and cerebral hemispheres are linked and how this information can be applied chiropractically. Chapters include information on patterning specific chiropractic adjustments for long-term corrections using 4 different types of neuromuscular retraining. Dr. Perri demonstrates how to monitor vasomotor mirror activity during viscerosomatic corrections, and discusses DeJarnette's CMRT profiles in the context of the Conjugate Gaze Adjustive Technique. A special chapter includes how to activate global mechanisms in chiropractic corrections, and how verbal cues and speech can be used to activate specific hemispheric responses. The final chapter discusses the neuroemotional components associated with dysfunctional states and specific techniques in working with them.
