“Chiropractic Research CASE SERIES Improvement in Post-Concussion Syndrome in Two Females Using Low-Force Upper Cervical Chiropractic Care: A Case Series & Review of the Literature Jonathan Chung D.C.1 ABSTRACT Objective: The purpose of this report is to describe the positive health outcomes of two patients with persistent post- concussion syndrome presenting to a chiropractic clinic utilizing a low-force upper cervical technique. Clinical Features: A 16-year old female with vertigo, brain fog, and headaches for 3 months after head trauma from a fall off a horse was diagnosed with post-concussion syndrome by a neurologist. A 30-year old female with migraine headache and vertigo following a motor vehicle accident where she struck her head against the steering wheel. Both patients had no previous history of vertigo or headache prior to the described head trauma. Intervention and Outcomes: Both patients were managed by a medical neurologist and had previously received Diversified-style chiropractic adjustments. At the time of presentation to the upper cervical chiropractor, there was no change in symptoms reported for vertigo or headache. Both patients reported reduction in frequency and intensity of headache and vertigo episodes shortly after beginning upper cervical chiropractic care. At a one-year follow up, the 30- year-old female experienced full resolution of headache and dizziness symptoms while the 16-year-old female experienced a re-occurrence of symptoms that resolved after upper cervical adjustment. Conclusion: Low-force upper cervical technique to correct atlas subluxation complex may be an effective intervention for patients with post-concussion syndrome of cervicogenic origin. More studies are needed to determine the role of chiropractic in the care of patients with post-concussion syndrome.

  • The Effects of Chiropractic Spinal Manipulation on Central
    www.nature.com/scientificreports OPEN The efects of chiropractic spinal manipulation on central processing of tonic pain - a pilot study using Received: 10 September 2018 Accepted: 8 April 2019 standardized low-resolution brain Published: xx xx xxxx electromagnetic tomography (sLORETA) Muhammad Samran Navid 1,2,3, Dina Lelic1, Imran Khan Niazi 3,4,5, Kelly Holt3, Esben Bolvig Mark1, Asbjørn Mohr Drewes1,2 & Heidi Haavik3 The objectives of the study were to investigate changes in pain perception and neural activity during tonic pain due to altered sensory input from the spine following chiropractic spinal adjustments. Fifteen participants with subclinical pain (recurrent spinal dysfunction such as mild pain, ache or stifness but with no pain on the day of the experiment) participated in this randomized cross-over study involving a chiropractic spinal adjustment and a sham session, separated by 4.0 ± 4.2 days. Before and after each intervention, 61-channel electroencephalography (EEG) was recorded at rest and during 80 seconds of tonic pain evoked by the cold-pressor test (left hand immersed in 2 °C water). Participants rated the pain and unpleasantness to the cold-pressor test on two separate numerical rating scales. To study brain sources, sLORETA was performed on four EEG frequency bands: delta (1–4 Hz), theta (4–8 Hz), alpha (8–12 Hz) and beta (12–32 Hz). The pain scores decreased by 9% after the sham intervention (p < 0.05), whereas the unpleasantness scores decreased by 7% after both interventions (p < 0.05). sLORETA showed decreased brain activity following tonic pain in all frequency bands after the sham intervention, whereas no change in activity was seen after the chiropractic spinal adjustment session.

  • The Chiropractic Adjuster (1921)
    THE CHIROPRACTIC ADJUSTER A Compilation of the Writings of D. D. PALMER by his son B. J. PALMER. D. C., Ph. C. President THE PALMER SCHOOL OF CHIROPRACTIC Davenport, Iowa, U. S. A. The Palmer School of Chiropractic Publishers Davenport, Iowa Copyright, 1921 B. J. PALMER, D. C., Ph. C. Davenport, Iowa, U. S. A. PREFACE My father was a prolific writer. He wrote much on many subjects. Some were directly apropos to chiropractic, many of them were foreign to it. He was very versatile in thinking, writing and speaking. He was a broad reader and a radical thinker. Away back in the years past, when I was but a boy, I recall going to his waste-basket each night, picking out the many sheets of long-hand, hand-written copies of his writings. I saved them. I saved them through the years, as much as I could. The compilation of these constituted my first step towards a scrapbook. Although chiropractic was not so named until 1895, yet the naming of “chiropractic” was much like the naming of a baby; it was nine months old before it was named. Chiropractic, in the beginning of the thoughts upon which it was named, dates back at least five years previous to 1895. During those five years, as I review many of these writings, I find they talk about various phases of that which now constitutes some of the phases of our present day philosophy, showing that my father was thinking along and towards those lines which eventually, suddenly crystallized in the accidental case of Harvey Lillard, after which it sprung suddenly into fire and produced the white hot blaze.

THE SUNRISE REVIEW PROCESS A sunrise review is an evaluation of a proposal to change the laws regulating health professions in Washington. The Washington State Legislature’s intent, as stated in chapter 18.120 RCW, is to permit all qualified people to provide health services unless there is an overwhelming need for the state to protect the interests of the public by restricting entry into the profession. Changes to the scope of practice should benefit the public. The Sunrise Act (RCW 18.120.010) says a health care profession should be regulated or scope of practice expanded only when: Unregulated practice can clearly harm or endanger the health, safety or welfare of the public, and the potential for the harm is easily recognizable and not remote or dependent upon tenuous argument; The public needs and can reasonably be expected to benefit from an assurance of initial and continuing professional ability; and The public cannot be effectively protected by other means in a more cost-beneficial manner.

Lee Iacocca, in his book about LIBERTY said: I know that liberty brings with it some obligations. I know we have it today because others fought for it, nourished it, protected it, and then passed it on to us. That is a debt we owe. We owe it to our parents, if they are alive, and to their memory if they are not. But mostly we have an obligation to our own kids. An obligation to pass on this incredible gift to them. This is how civilization works... whatever debt you owe to those who came before you, you pay to those who follow. That is essentially the same responsibility each of us has to preserve and protect the extraordinary history of this great profession.

The care path was developed by Cleveland Clinic’s Center for Spine Health with input from Department of Pain Management staff like Dr. Berenger. One goal was to match appropriate treatments and providers to patients at various points along the care continuum for low back pain. “We know acute back pain is common and often resolves with simple therapy or even no therapy,” Dr. Berenger says. “For patients without red flags, imaging is rarely required.” These patients may be best served through prompt access to care from physical therapists or nurse practitioners as entry-level providers.

    Joint Bone Spine 70 (2003) 336–341 www.elsevier.com/locate/bonsoi Review Mechanism of action of spinal manipulative therapy Jean-Yves Maigne a,*, Philippe Vautravers b a Physical Medicine Department, Hôtel-Dieu Teaching Hospital, Place du Parvis de Notre-Dame, 75004 Paris, France b Physical Medicine Department, Hautepierre Teaching Hospital, Strasbourg, France Received 9 April 2002; accepted 15 November 2002 Abstract Spinal manipulative therapy (SMT) acts on the various components of the vertebral motion segment. SMT distracts the facet joints, with faster separation when a cracking sound is heard. Intradiscal pressure may decrease briefly. Forceful stretching of the paraspinal muscles occurs, which induces relaxation via mechanisms that remain to be fully elucidated. Finally, SMT probably has an inherent analgesic effect independent from effects on the spinal lesion. These changes induced by SMT are beneficial in the treatment of spinal pain but short-lived. To explain a long-term therapeutic effect, one must postulate a reflex mechanism, for instance the disruption of a pain–spasm–pain cycle or improvement of a specific manipulation-sensitive lesion, whose existence has not been established to date. © 2003 Éditions scientifiques et médicales Elsevier SAS.
