This paper describes the first known description of the ‘idea of subluxation’ as a small dysfunction in the spine which affected a person’s health and function. The authoritative source document is the Edwin Smith Manuscript, introduced to the world in the 1920s. This paper reports this interpretation of Egyptian medical writings dating from 1,600 BC and earlier, in which small spinal dysfunctions were noted and clinically managed.

Introduction


Figure 1

Clues to the antiquity of the idea that DD Palmer codified as ‘subluxated vertebrae modulating tone’ came as early as 1905 [1] when he referred to ‘Chinese and Egyptian history … system of healing … Manual Therapeutics.’ (Figure 1)

Palmer alluded to this history [2] in his 1906 text co-written with his son, BJ Palmer but was clear in his 1910 tome, on p. 12, [3] where he wrote:

‘Dr. Atkinson [4–6] has frequently informed me that the replacing of displaced vertebrae for the relief of human ills had been known and practiced by the ancient Egyptians for at least 3000 years.’

and on p. 13:

‘many of the methods employed in ancient Greece and older Egypt are being restored’

In 1914 Palmer wrote: [7, p. 8]

‘The principles which form chiropractic science have always existed; and are now being revealed to the world by D. D. Palmer’

In this paper we synthesize an expansive body of literature examining the multifaceted influence of chiropractic care on processes within and modulators of the neuroendocrine-immune (NEI) system, for the purpose of generating an inductive hypothesis regarding the potential impacts of chiropractic care on integrated physiology. Taking a broad, interdisciplinary, and integrative view of two decades of research-documented outcomes of chiropractic care, inclusive of reports ranging from systematic and meta-analysis and randomized and observational trials to case and cohort studies, this review encapsulates a rigorous analysis of research and suggests the appropriateness of a more integrative perspective on the impact of chiropractic care on systemic physiology. A novel perspective on the salutogenic, health-promoting effects of chiropractic adjustment is presented, focused on the improvement of physical indicators of well-being and adaptability such as blood pressure, heart rate variability, and sleep, potential benefits that may be facilitated through multiple neurologically mediated pathways. Our findings support the biological plausibility of complex benefits from chiropractic intervention that is not limited to simple neuromusculoskeletal outcomes and open new avenues for future research, specifically the exploration and mapping of the precise neural pathways and networks influenced by chiropractic adjustment.

Increasing evidence suggests that a high-velocity, low-amplitude (HVLA) thrust directed at a dysfunctional vertebral segment in people with subclinical spinal pain alters various neurophysiological measures, including somatosensory evoked potentials (SEPs). We hypothesized that an HVLA thrust applied to a clinician chosen vertebral segment based on clinical indicators of vertebral dysfunction, in short, segment considered as “relevant” would significantly reduce the N30 amplitude compared to an HVLA thrust applied to a predetermined vertebral segment not based on clinical indicators of vertebral dysfunction or segment considered as “non-relevant”. In this double-blinded, active-controlled, parallel-design study, 96 adults with recurrent mild neck pain, ache, or stiffness were randomly allocated to receiving a single thrust directed at either a segment considered as “relevant” or a segment considered as “non-relevant” in their upper cervical spine. SEPs of median nerve stimulation were recorded before and immediately after a single HVLA application delivered using an adjusting instrument (Activator). A linear mixed model was used to assess changes in the N30 amplitude. A significant interaction between the site of thrust delivery and session was found (F1,840 = 9.89, p < 0.002). Pairwise comparisons showed a significant immediate decrease in the N30 complex amplitude after the application of HVLA thrust to a segment considered "relevant" (- 16.76 ± 28.32%, p = 0.005). In contrast, no significant change was observed in the group that received HVLA thrust over a segment considered "non-relevant" (p = 0.757). Cervical HVLA thrust applied to the segment considered as "relevant" altered sensorimotor parameters, while cervical HVLA thrust over the segment considered as "non-relevant" did not. This finding supports the hypothesis that spinal site targeting of HVLA interventions is important when measuring neurophysiological responses. Further studies are needed to explore the potential clinical relevance of these findings.

Purpose:   An approach to systematically perform clinical work-up for chiropractic subluxation is proposed. Literature on assessment approaches is reviewed and a discussion is presented.

Method:   A qualitative review of clinical and scientific literature related to assessment methodologies for subluxation was performed.

Summary:   Variation in assessment techniques exists for identification of spinal and other articular joint dysfunction. Useful scientific data also are limited to only a few approaches, and there is a need for a more systematic assessment approach profession wide.

Key words:   Articular range of motion, chiropractic, Medicare, palpation, physical examination, subluxation

Background

Doctors of chiropractic are portals of entry to the health care system for many patients seeking health care services. As such, they must maintain broad and thorough assessment/diagnostic skills. Before employing any therapy, a clinician must first determine if there is a need for treatment. Therefore, the clinical information that any primary contact provider would want, including a case history, physical examination, clinical laboratory findings, radiographic findings, and any other tests necessary to check for suspected health problems, is needed. Having gathered and interpreted this information, it must be processed in order to arrive at a sound clinical conclusion.

Chiropractic Lexicon: Useful or Not?

Obtaining an ultimate definition of this ‘something’ we have been addressing, successfully, for over 125 years is elusive, yet this allows flexibility when defining it within different contexts. This provides space for chiropractors to do this (both consciously and subconsciously) every day in practice, and over time to use their growing experience to add complexity and subtlety to their conceptual framework, and their application of their science and art. Millions of patients over the years would attest to the value in that.

      We all address something

For well over a century, chiropractors have successfully been addressing ‘something’, primarily within the spine and its adjacent structures. They observed a phenomenon and devised ways to impact upon it. This resulted in health outcomes significant enough to grow a profession, and an associated body of literature evidence.

      Words were chosen

It was chosen early on to use the term subluxation, which is understandable as it often feels to palpation that some sort of misplacement is involved. Right from the very start, it was more than a ‘bone out of place’. Neurological involvement was part of the concept from the beginning, endeavouring to explain the body-wide effects that were observed.

      Concepts were developed

Over the years, conceptual frameworks for the ‘something’ were developed. This conceptual development was significantly clinician-driven and therefore, one would imagine, informed and motivated by patient outcomes; to this day our great strength. With time, these frameworks gained considerable complexity, and diversity. Again, this is understandable, as human beings are both complex and diverse. For example, the SOT group had a focus on dural attachments, CSF flow, and their relationship to the functioning of the sacrum and cranium; the various upper cervical techniques zeroed-in on adjusting C0, C1 and C2; Logan had more of a base-up approach, as did Gonstead, etc.

Purpose:   There is growing evidence that vertebral column function and dysfunction play a vital role in neuromuscular control. This invited review summarises the evidence about how vertebral column dysfunction, known as a central segmental motor control (CSMC) problem, alters neuromuscular function and how spinal adjustments (high-velocity, low-amplitude or HVLA thrusts directed at a CSMC problem) and spinal manipulation (HVLA thrusts directed at segments of the vertebral column that may not have clinical indicators of a CSMC problem) alters neuromuscular function.

Methods:   The current review elucidates the peripheral mechanisms by which CSMC problems, the spinal adjustment or spinal manipulation alter the afferent input from the paravertebral tissues. It summarises the contemporary model that provides a biologically plausible explanation for CSMC problems, the manipulable spinal lesion. This review also summarises the contemporary, biologically plausible understanding about how spinal adjustments enable more efficient production of muscular force. The evidence showing how spinal dysfunction, spinal manipulation and spinal adjustments alter central multimodal integration and motor control centres will be covered in a second invited review.

Results:   Many studies have shown spinal adjustments increase voluntary force and prevent fatigue, which mainly occurs due to altered supraspinal excitability and multimodal integration. The literature suggests physical injury, pain, inflammation, and acute or chronic physiological or psychological stress can alter the vertebral column’s central neural motor control, leading to a CSMC problem. The many gaps in the literature have been identified, along with suggestions for future studies.
