Reviewing Pederick’s 1997 Framework for Scientific Appraisal Cranial adjusting has long occupied a debated space within chiropractic and osteopathic practice. In 1997, Frank O. Pederick published a thoughtful analysis in Chiropractic Technique titled “A Kaminski-type Evaluation of Cranial Adjusting.” Rather than simply defending cranial techniques, Pederick applied an evaluative model — often attributed to Kaminski’s framework for assessing chiropractic methods — to systemat

Insights from Indahl et al. (1999) The sacroiliac (SI) joint is often discussed as a source of low back pain — but does it also play an active role in neuromuscular control? A pivotal animal study by Indahl, Kaigle, Reikeras, and Holm, published in the Journal of Spinal Disorders , investigated whether stimulation of the sacroiliac joint could trigger muscular activation in the trunk and hip. Their findings suggest the SI joint is not just a passive structure — it may be part

Why This Anatomy May Matter in Headache and Neck Pain In the proceedings of the 2000 International Conference of Spinal Manipulation, Kenin, Humphreys, Hubbard, and Cramer reported important findings regarding connective tissue attachments between the spinal dura and the posterior cervical structures. Their study, Attachments from the Spinal Dura to the Ligamentum Nuchae: Incidence, MRI Appearance, and Strength of Attachment , explored whether consistent anatomical connection

A Review of Crisera (2001) In 2001, P. Crisera published a thought-provoking paper in Medical Hypotheses proposing a unifying biological rhythm termed primary respiration (PR) . Rather than focusing solely on pulmonary breathing, Crisera suggested that a deeper oscillatory rhythm may exist at the cellular level — potentially coordinating life from DNA to the central nervous system. This article is theoretical in nature, but it attempts to bridge cytology, neurobiology, embry

A Review of Oleski, Smith & Crow (2002) Can cranial bone movement be measured objectively? A 2002 study published in CRANIO: The Journal of Craniomandibular Practice by Oleski, Smith, and Crow sought to answer that question by examining whether cranial manipulation produced measurable changes on radiographs. The Question: Do Cranial Bones Move? The concept of cranial bone mobility has long been central to cranial osteopathic and manual therapy traditions. However, critics ha

Insights from Rivera-Martinez et al. (2002) In 2002, Rivera-Martinez, Wells, and Capobianco published a retrospective study in the Journal of the American Osteopathic Association examining whether patients with idiopathic Parkinson's disease demonstrate distinctive cranial strain patterns. The study explored an intriguing clinical observation: Do patients with Parkinson’s exhibit consistent cranial findings detectable through osteopathic examination? Why This Question Matter
