OBJECTIVE: To examine cerebral arterial blood flow in 2 @entity1 exhibiting @entity9085 (VBI) before and after spinal manipulative therapy. CLINICAL FEATURES: Two @entity1 had a repetitive/resting @entity400 , one from a spastic torticollis with the onset immediately after self-manipulation by the @entity1 6 months earlier, and the second one with a generalized resting @entity400 , hip clonus, dizziness, and @entity1163 . The diagnosis of @entity9085 was established by continuous wave Doppler ultrasound and physical examination. INTERVENTION AND OUTCOME: Nonrotary cervical manipulation and diversified technique to the thoracic spine were performed. In the first @entity1 , the spastic @entity400 improved by 80%. The repeat Doppler performed 13 months later showed an improvement in the arterial flow in the right external carotid artery peak flow from 0.7 kHz to 1.75 kHz. In the second @entity1 , the resting @entity400 diminished in 4 days, with the right common carotid artery peak systolic flow improving from 1.0 kHz to 1.9 kHz and the left vertebral artery flow improving from 0.175 kHz to 0.5 kHz. The symptoms of VBI and objective Doppler findings improved following spinal manipulation. Both cases had impaired vertebral arterial flow. CONCLUSION: Spinal manipulation may have a normalizing effect on the sympathetic nervous system, allowing for a change in @entity455 .
