Vascular Ultrasound Measurements After Atlas Orthogonal Chiropractic Care in a Patient With Bow Hunter Syndrome

Abstract

Objective: This case report describes chiropractic treatment for a patient diagnosed with bow hunter syndrome with transient vision loss (TVL). Clinical Features: A 39-year-old woman presented to a chiropractic clinic with hand and arm numbness that began after she was injured in a motor vehicle collision 18 months earlier. The primary symptom was TVL that began 3 days after the motor vehicle collision. At that time, she had been diagnosed with bow hunter syndrome using dynamic angiography findings. She had previously declined surgery recommended by her attending neurosurgeon at a local hospital. Intervention and Outcome: The patient was treated using atlas orthogonal chiropractic technique for 8 visits over a 6-week period. Examination before and the after the initial treatment included cervical radiographic analysis and vascular ultrasound measurement of the right and the left vertebral artery (VA). After the initial spinal manipulation, there was an improvement in blood flow volume of 8.2% in the left VA and 22.2% in the right VA. There was improvement of the symptom of TVL and a measured reduction of rotational misalignment of the first and second cervical vertebra on the radiographic views. After 6 weeks, the patient's perception of TVL was absent. Conclusion: A patient with TVL improved under chiropractic care using atlas orthogonal technique.

Chiropractic Management of Neck Pain Complicated by Symptomatic Vertebral Artery Stenosis and Dizziness

“…There were 4 previously published cases of patients with known VBI receiving chiropractic SMT [ 41 , 53 , 54 ] ( Table 1 ). Including the current case (5 total), patients were a mean age of 42.2±11.0 years, and 3/5 (60%) were female.…”

“…The most common imaging modality, in 3/5 (60%) was Doppler sonography, which demonstrated decreased vertebral artery flow [ 41 , 54 ], which was related to an anomalous vertebrobasilar arterial system in 1 case [ 41 ] and in the other 2 cases was unclear [ 54 ]. One patient had dynamic angiography revealing rotational vertebral artery occlusion [ 53 ]. None of the included patients had vertebral artery dissection.…”

EPIC Spinal Procedure with Sound Wave Technology Induces Biomechanical Alignment Putatively Influencing Pain Response

“…In the 1970s, Roy Sweat, DC, developed a 2-axis, table-mounted, adjusting instrument that could deliver a percussive soundwave to align the upper cervical spine [3]. In 2001, the lead author, Stan Pierce, DC, and his father, Stan Pierce Sr., DC, advanced and refined the radiographic analysis protocol to include data transposition between radiographs for anatomical clarity, methods to validate reference line determination and measurement accuracy, and evaluation methods to determine genetic abnormalities that would affect the understanding of each patient's "normal" position into which they needed to be adjusted [4]. This technique was known as the Advanced Orthogonal technique, involving streamlined imaging analysis to assist in removing analysis errors through advanced software coding [5].…”
