June 7, 2019 -- The Academy for
Radiology & Biomedical Imaging Research has recognized Logan
radiology adjunct faculty member Vitaly Napadow PhD, LicAc. with
the Academy’s 2019 Distinguished Investigator Award.
Napadow is one of 37 researchers to receive the award, which recognizes
individuals for their accomplishments in the field of medical imaging. Recipients
represent the top 10 percent of all academic radiology faculty.
Dr. Napadow serves as director for
the Center for Integrative Pain Neuroimaging (CiPNI) and associate professor
for the Martinos Center for Biomedical Imaging at Massachusetts General
Hospital, the primary teaching hospital for Harvard Medical School.
In addition to serving as an adjunct
faculty member at Logan, Dr. Napadow has been a research collaborator with Norman
Kettner, DC, DACBR, FICC,
chair of Logan’s Department of Radiology, for nearly 20 years.
According to Elizabeth A. Krupinski,
PhD, co-chair of the Council of Distinguished Investigators, the award
recipients represent the future of research in radiology, advancing the field
and developing ways to significantly improve patient care through imaging.

March 21, 2019 -- Brain
Stimulation, a premier journal for original research in the field of
neuromodulation, has published research co-authored by Norman W. Kettner,
DC, DACBR, DCBCN, FICC, chair of Logan’s Department of Radiology.
The study looked at the vagus nerve,
which originates in the brain stem and is responsible for a variety of systems
operations in the body, including the cardiovascular, immune and metabolic.
Specifically, Dr. Kettner’s research wanted to determine if targeting vagal
nuclei in response to stimulation was enhanced when the stimulation was
delivered during exhalation.
To find out, researchers used a
multimodal ultrahigh-field (7T) fMRI to examine vagal nuclei in the brain stem
while applying a respiratory-gaited auricular vagal afferent nerve stimulation
(RAVENS) technique. The transcutaneous electrical stimulation was applied in
the ear at the cymba conchae. The results demonstrated that targeting was
indeed enhanced during exhalation. This work will translate to
nonpharmacological approaches for modulating brain activity in chronic pain and
other neurological conditions.
Dr. Kettner’s co-researchers
included Roberta Sclocco, PhD, and Vitaly Napadow, PhD, who are affiliated with
Logan University, Department of Radiology through the Athinoula A. Martinos
Center for Biomedical Imaging at Massachusetts General Hospital.
Dr. Kettner said he was honored to
have research accepted by Brain
Stimulation. “The journal focuses on research that promises to
noninvasively modulate the nervous system and function of the brain,” he said.
“Our research achieved that, and offers a brand new field of study.”
November 27, 2018 -- Logan’s College of Chiropractic has entered into an affiliation agreement to establish a preceptorship program with The Medical College of Wisconsin (MCW) Department of Neurosurgery.
Under the direction of Jeff King, DC, MS, 2011 graduate of Logan University, who serves as an assistant professor at MCW, Logan student interns will receive clinical training in a high-quality patient care delivery system. The goal of the preceptorship program is to enhance patient care, education and research opportunities for both institutions.
“We are very excited to expand the number of schools participating in our preceptorship program,” said Dr. King. “Our hope is that by offering this transdisciplinary educational opportunity we can encourage students to have an interest in reaching across professions to provide the best possible care for their patients during their clinical careers.”
During 2018, Logan placed approximately 165 student interns in preceptorship programs with organizations, institutions and private practices around the world. Preceptorships at MCW will start in May 2019 wherein eligible students will go through a selection process.
Chair of Logan’s Department of Radiology Norman Kettner, DC, DACBR, FICC said Dr. King will bring awareness of patient-centered and cost-effective chiropractic care delivered in a multidisciplinary clinical environment, where he daily interacts across a range of specialties and disciplines. “This clinical environment is what the future is likely to reveal: chiropractic physicians directly integrated into the health care system,” he said.
November 13, 2018 -- Congratulations are due to Norman W. Kettner, DC, DACBR, DCBCN, FICC, chair of Logan’s Department of Radiology, whose collaborative research was published this week in Journal of Pain.
The research explored clinical and neuroimaging responses of spinal manipulative therapy (SMT) in chronic low back pain. It demonstrates reduction of pain, expectation of pain, fear-related movement and the corresponding brain imaging responses.
According to the study, learning and memory (implicit) processes, such as habituation, sensitization and operant conditioning, are determinants of chronic low back pain. Perception of pain takes place when potential or actual noxious stimuli are appraised as threats. Maladaptive neuroplastic structural and functional brain changes evolve from these learning processes to initiate changes in pain perception. The reversal of these maladaptive brain changes reduces chronic pain. One method of achieving this is through SMT, which generates salient sensory and proprioceptive feedback that may disrupt the relationship between pain anticipation, fear and movement.
The research was partly funded by National Chiropractic Mutual Insurance Company and was a collaboration between Logan University, Athinoula A. Martinos Center for Biomedical Imaging, the Osher Center for Integrative Medicine―a partnership between Brigham and Women’s Hospital and Harvard Medical School―and Melrose Family Chiropractic.

November 9, 2018 -- This
past summer, Logan welcomed Roberta Sclocco, PhD, to campus for a Chiropractic
Grand Rounds presentation. Dr. Sclocco is a research fellow at Athinoula A.
Martinos Center for Biomedical Imaging at Massachusetts General Hospital and
Harvard Medical School. Her presentation, titled “Transcutaneous Vagus Nerve
Stimulation Optimized Using Functional MRI” focused on the application and
integration of advanced imaging techniques and brainstem neural science. This
work is an ongoing line of research with which Norman Kettner, DC, DACBR, FICC
and Chair of Logan’s Department of Radiology is a collaborator.
introduction to Dr. Sclocco’s presentation, Dr. Kettner explained the
importance the vagus nerve plays in many major biological systems.
inflammatory reflex is a physiological mechanism through which the vagus nerve
regulates immune function, inhibits excessive proinflammatory cytokine
production and may provide a variety of biological, psychological and
behavioral health benefits addressing the elements of the biopsychosocial model,”
he said. “Vagus nerve signaling plays an important role in the regulation of
feeding behavior, gut regulation, immune network interaction, pain modulation
and metabolic homeostasis. Cholinergic signaling (inflammatory reflex) is known
to alleviate obesity-associated inflammation and metabolic derangement and
could be exploited for treatment of metabolic syndrome, type II diabetes mellitus
and other obesity-driven disorders. “
particular importance to the current opioid epidemic, vagus stimulation has
been shown to alter the pain memory process and free chronic pain patients from
conditioned pain responses.
Sclocco describes her research as a merging of the head and the heart and an
exploration of whether something useful can come out of integrating the two
modalities. This research has employed subcutaneous stimulation of the vagus
nerve (auricular branch) with 7 T fMRI to better understand the treatment and
its underlying neural mechanisms. Click here to watch the full presentation.
