Analysis and Adjustment of Vertebral Subluxation as a Separate and Distinct Identity for the Chiropractic Profession: A Commentary

Development and validation of the Chiropractic Professional Identity Embodiment Scale (CPIES)

BACKGROUND AND PURPOSE

Chiropractic professional identity (CPI) encompasses diverse values, beliefs, experiences, and philosophies about one's work, specific to the chiropractic profession. Yet currently, there is no instrument available to measure CPI. This study aimed to develop and validate the Chiropractic Professional Identity Embodiment Scale (CPIES).

MATERIALS AND METHODS

A mixed-methods sequential exploratory design was employed where qualitative inquiry preceded quantitative analysis of survey items conducted in New Zealand in 2022. Expert key informants provided feedback on candidate items via one-to-one cognitive interviews. Candidate items were administered to Board-registered chiropractors or chiropractic students through an online survey. The suitability of candidate items was evaluated using a variety of psychometric analyses including conceptually guided exploratory factor analysis (EFA) and reliability testing.

RESULTS

Based on relevant professional identity literature and feedback from 15 expert key informants, a draft survey instrument with 92 candidate items (across six domains) was rated by 231 participants. Using EFA, the number of items was reduced to 15. The CPIES sum score exhibited significant correlations with individuals' philosophical self-categorisation and five of the six optional subscales.

CONCLUSION

The 15-item CPIES, either as a unidimensional score or with six separate subscale scores, has been demonstrated to provide valid and reliable measurement of CPI. Future research could utilise the CPIES to investigate how CPI influences clinical practice, patient outcomes, career satisfaction, and public perception of the chiropractic profession, further advancing professionalisation and recognition within healthcare.

The paradox of the impact of the COVID-19 pandemic on massage therapists in Australia and Canada: The reporting of a qualitative strand of a mixed methods study

INTRODUCTION

In both Australia and Canada, healthcare providers considered essential were allowed to operate during the COVID-19 pandemic. The impact of the global pandemic on professional identity included opportunities for role expansion, a focus on ethical principles and social accountability, and professional pride. These results were found only for those considered to be essential and do not likely resonate with those classified as non-essential, such as massage therapists, leaving a gap in understanding.

MATERIALS AND METHODS

This qualitative strand of a sequential explanatory mixed methods study used qualitative description. Individuals who expressed interest were purposefully selected, based on age, gender, type of practice, and experience with the four key phenomena of interest. Data collected through semi-structured interviews was analyzed using qualitative content analysis. Member checking enhanced the trustworthiness of the results.

RESULTS

Thirty-one (16 Australian and 15 Canadian) participants were interviewed. The main theme described was the pandemic paradox. At some point during the pandemic, most participants were labelled by government agencies as a non-essential service. However, participants reported feeling both essential and non-essential. Two subthemes were also described: factors contributing to creating the paradox and consequences of the paradox.

CONCLUSION

A number of pre-existing factors around professional identity, such as patient relationships combined with the conditions instituted to manage the COVID-19 pandemic included designating health care services as essential or non-essential, created the paradox experienced by respondents and the subsequent experience of moral distress. Further research into moral distress experienced by massage therapists is needed.

"Chiropractic is manual therapy, not talk therapy": a qualitative analysis exploring perceived barriers to remote consultations by chiropractors

Background

Remote consultations (RCs) enable clinicians to continue to support patients when face-to-face appointments are not possible. Restrictions to face-to-face care during the COVID-19 pandemic has accelerated a pre-existing trend for their adoption. This is true for many health professionals including some chiropractors. Whilst most chiropractors in the UK have used RCs in some form during the pandemic, others have not. This study seeks to understand the views of chiropractors not using RCs and to explore perceived potential barriers.

Methods

A national online survey was completed by 534 registered practicing UK chiropractors on the use of RCs. Respondents had the opportunity of providing open-ended responses concerning lack of engagement in RCs during the COVID-19 pandemic. Textual responses obtained from 137 respondents were coded and analysed using thematic analysis.

Results

The use of RCs provided an opportunity for chiropractors to deliver ongoing care during the COVID-19 pandemic. However, many chiropractors expressed concern that RCs misaligned with their strong professional identity of providing ‘hands-on’ care. Some chiropractors also perceived that patients expected physical interventions during chiropractic care and thus considered a lack of demand when direct contact is not possible. In the absence of a physical examination, some chiropractors had concerns about potential misdiagnosis, and perceived lack of diagnostic information with which to guide treatment. Clinic closures and change in working environment led to practical difficulties of providing remote care for a few chiropractors.

Conclusions

The COVID-19 pandemic may have accelerated changes in the way healthcare is provided with RCs becoming more commonplace in primary healthcare provision. This paper highlights perceived barriers which may lead to reduced utilisation of RCs by chiropractors, some of which appear fundamental to their perceived identity, whilst others are likely amenable to change with training and experience.

Reframing a debate in chiropractic

The chiropractic profession is 125 years old and has evolved a culture beset with internal conflict. The internal ructions have been particularly noticeable during the last 20 years. The recent resignation of the entire World Federation of Chiropractic Research Committee has again focussed the conflicting views and goals of the “wellness” and “evidence” factions within the profession. These polarising viewpoints are worsening to the degree that there are calls for the profession to break into two separate entities. Key to the recognition of the differences within the profession is the recognition of title for particular sub populations of patients presenting to chiropractors. For many of the sub populations such as sport or paediatrics there has grown appropriate post professional specialist educational training sometimes leading to a protected title. However, this is not occurring in that group of practitioners that choose to focus on wellness care. A recommendation is made that wellness chiropractic be viewed as a post professional specialty program within chiropractic, as it is in medicine and elsewhere, and that recognition follow after appropriate post professional educational programs have been completed, as is customary in the other special interest groups. In order to do so, consensus will be required from all stakeholders within the profession on the level, scope and depth of such programs. Furthermore, it is possible that different jurisdictions around the world may require different post graduate educational levels based on local competitive, legal and professional circumstances. In such cases, transitioning to the higher level over a period of time may be undertaken. Recognition of the wellness specialty by the profession would allow for vertical integration with other healthcare providers as well as help bridge a gap between the entrepreneur and academic groups that would be responsible for creating these programs at tertiary education institutions. Finally, should these programs acquire evidence to underpin them, a process that would be taught within the programs, it is likely that recognition of an extended scope of practice would occur increasing the appeal of chiropractic to the public.

Radiography and Clinical Decision-Making in Chiropractic

The concern over x-ray exposure risks can overshadow the potential benefit of radiography, especially in cases where manual therapy is employed. Spinal malalignment cannot be accurately visualized without imaging. Manual therapy and the load tolerances of injured spinal tissues raise different criteria for the use of x-rays for spinal disorders than in medical practice. Current regulatory bodies rely on radiography risk assessments based on Linear-No-Threshold (LNT) risk models. There is a need to consider radiography guidelines for chiropractic which are different from those for medical practice. Radiography practice guidelines are summaries dominated by frequentist interpretations in the analysis of data from studies. In contrast, clinicians often employ a pseudo-Bayesian form of reasoning during the clinical decision-making process. The overrepresentation of frequentist perspectives in evidence-based practice guidelines alter decision-making away from practical assessment of a patient's needs, toward an overly cautious standard applied to patients without regard to their risk/benefit likelihoods relating to radiography. Guidelines for radiography in chiropractic to fully assess the condition of the spine and spinal alignment prior to manual therapy, especially with high velocity, low amplitude spinal manipulation (HVLA-SM), should necessarily differ from those used in medical practice.

The contemporary model of vertebral column joint dysfunction and impact of high-velocity, low-amplitude controlled vertebral thrusts on neuromuscular function

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.

Conclusion

Spinal adjustments of CSMC problems impact motor control in a variety of ways. These include increasing muscle force and preventing fatigue. These changes in neuromuscular function most likely occur due to changes in supraspinal excitability. The current contemporary model of the CSMC problem, and our understanding of the mechanisms of spinal adjustments, provide a biologically plausible explanation for how the vertebral column’s central neural motor control can dysfunction, can lead to a self-perpetuating central segmental motor control problem, and how HVLA spinal adjustments can improve neuromuscular function.

The Effects of 4 Weeks of Chiropractic Spinal Adjustments on Motor Function in People with Stroke: A Randomized Controlled Trial

Chiropractic spinal adjustments have been shown to result in short-term increases in muscle strength in chronic stroke patients, however, the effect of longer-term chiropractic spinal adjustments on people with chronic stroke is unknown. This exploratory study assessed whether 4 weeks of chiropractic spinal adjustments, combined with physical therapy (chiro + PT), had a greater impact than sham chiropractic with physical therapy (sham + PT) did on motor function (Fugl Meyer Assessment, FMA) in 63 subacute or chronic stroke patients. Secondary outcomes included health-related quality of life and other measures of functional mobility and disability. Outcomes were assessed at baseline, 4 weeks (post-intervention), and 8 weeks (follow-up). Data were analyzed using linear mixed-effects models or generalized linear mixed models. A post-hoc responder analysis was performed to investigate the clinical significance of findings. At 4 weeks, there was a larger effect of chiro + PT, compared with sham + PT, on the FMA (difference = 6.1, p = 0.04). The responder analysis suggested the improvements in motor function seen following chiropractic spinal adjustments may have been clinically significant. There was also a robust improvement in both groups in most measures from baseline to the 4- and 8-week assessments, but between-group differences were no longer significant at the 8-week assessment. Four weeks of chiro + PT resulted in statistically significant improvements in motor function, compared with sham + PT, in people with subacute or chronic stroke. These improvements appear to be clinically important. Further trials, involving larger group sizes and longer follow-up and intervention periods, are required to corroborate these findings and further investigate the impacts of chiropractic spinal adjustments on motor function in post-stroke survivors.

Chiropractic students' cognitive dissonance to statements about professional identity, role, setting and future: international perspectives from a secondary analysis of pooled data

BACKGROUND

Chiropractic students demonstrate philosophically opposing views about the chiropractic profession. The primary aim was to describe chiropractic students' responses to statements about chiropractic identity, role, setting, and future direction. A secondary aim was to describe the frequency of internally conflicting responses.

METHODS

Three datasets from Europe, North America, and Australia/New Zealand were pooled in a secondary data analysis. Chiropractic students from 25 chiropractic training institutions completed interrelating surveys (combined response rate 21.9%) between 2013 and 2018. The survey instrument investigated student viewpoints about chiropractic professional identity, role, practice setting and future direction of chiropractic practice. Student attitudes about chiropractic were described using weighted proportions to adjust for unequal population sampling across the three geographical regions. The frequency of concordant and discordant student responses was described by combining identity items with items that explored responses about practice role, setting and future direction. The relationship between student characteristics (age, sex, education, association membership and geographical region) and ideologically conflicting responses were assessed using the Chi-squared test and Cramér's V.

RESULTS

Data from 2396 student chiropractors (50.8% female; from Europe 36.2%, North America 49.6% and Australia/New Zealand 14.5%) were analysed. For identity, nearly half of the chiropractic students (weighted 45.1%) agreed that it is important for chiropractors to hold strongly to the traditional chiropractic theory that adjusting the spine corrects "dis-ease" and agreed (weighted 55.5%) that contemporary and evolving scientific evidence is more important than traditional chiropractic principles. The frequency of discordant (ideologically conflicting) student responses ranged from 32.5% for statements about identity versus role, to 51.4% for statements about identity versus future. There was no association between student age, sex and internally conflicting responses. Chiropractic students' professional association membership status, pre-chiropractic education and geographical region were associated with ideologically conflicting responses.

CONCLUSIONS

Chiropractic students in this analysis show traditional and progressive attitudes towards the chiropractic profession. Individual student responses frequently contradict in terms of professional ideology, but most (approximately half) students demonstrate concordant progressive and mainstream attitudes. Ideological conflict may raise concerns about some students' ability to learn and make clinical judgements, and potential for disharmony in the chiropractic fraternity.

Vitalism in contemporary chiropractic: a help or a hinderance?

BACKGROUND

Chiropractic emerged in 1895 and was promoted as a viable health care substitute in direct competition with the medical profession. This was an era when there was a belief that one cause and one cure for all disease would be discovered. The chiropractic version was a theory that most diseases were caused by subluxated (slightly displaced) vertebrae interfering with "nerve vibrations" (a supernatural, vital force) and could be cured by adjusting (repositioning) vertebrae, thereby removing the interference with the body's inherent capacity to heal. DD Palmer, the originator of chiropractic, established chiropractic based on vitalistic principles. Anecdotally, the authors have observed that many chiropractors who overtly claim to be "vitalists" cannot define the term. Therefore, we sought the origins of vitalism and to examine its effects on chiropractic today.

DISCUSSION

Vitalism arose out of human curiosity around the biggest questions: Where do we come from? What is life? For some, life was derived from an unknown and unknowable vital force. For others, a vital force was a placeholder, a piece of knowledge not yet grasped but attainable. Developments in science have demonstrated there is no longer a need to invoke vitalistic entities as either explanations or hypotheses for biological phenomena. Nevertheless, vitalism remains within chiropractic. In this examination of vitalism within chiropractic we explore the history of vitalism, vitalism within chiropractic and whether a vitalistic ideology is compatible with the legal and ethical requirements for registered health care professionals such as chiropractors.

CONCLUSION

Vitalism has had many meanings throughout the centuries of recorded history. Though only vaguely defined by chiropractors, vitalism, as a representation of supernatural force and therefore an untestable hypothesis, sits at the heart of the divisions within chiropractic and acts as an impediment to chiropractic legitimacy, cultural authority and integration into mainstream health care.

Moving towards a contemporary chiropractic professional identity

Since the inception of the chiropractic profession, debate has continued on differing practice objectives and philosophical approaches to patient care. While the political and academic leaders of the profession continue to dominate the discourse, little is known on the perspectives of the everyday practising chiropractor on their professional identity. In this paper, professional identity within the profession of chiropractic was evaluated using a systematised search strategy of the literature from the year 2000 through to May 2019. Initially 562 articles were sourced, of which 24 met the criteria for review. The review confirmed three previously stated professional identity subgroups; two polarised approaches and a centrist or mixed view. The musculoskeletal biomedical approach is in contrast to the vertebral subluxation vitalistic practice approach. Whilst these three main chiropractic identity subtypes exist, within the literature the terminology used to describe them differs. Research aimed at categorising the chiropractic profession identity into exclusive subtypes found that at least 20% of chiropractors have an exclusive vertebral subluxation focus. However, deeper exploration of the literature shows that vertebral subluxation is an important practice consideration for up to 70% of chiropractors. Patient care with a musculoskeletal spine focus is dominant in clinical practice. This review found that practising chiropractors consider themselves to be primary care or primary contact practitioners with a broad scope of practice across a number of patient groups not limited to musculoskeletal management. Across the research, there is a marked difference in the categories of practice objectives evaluated, and future research could examine the relatedness of these. Additionally, future research could explore the professional identity construct over time and within different practice contexts to help facilitate the progression of the profession.

“I am a healthcare practitioner”: A qualitative exploration of massage therapists’ professional identity

Background

A division has been described among massage therapists, some who identify as healthcare providers while others identify as service providers. The perceived division creates confusion about what it means to be a massage therapist.

Objective

This qualitative study answered, “How do massage therapists in Ontario describe their professional identity?”

Methods

Qualitative description (QD) was used and data were collected from 33 massage therapists using semi-structured interviews.

Results

The resulting description of massage therapists’ identity in Ontario is the first of its kind. The identity described includes passion as professional motivation in practice, the importance of confidence and competence, a focus on the therapeutic relationship, individualized care, and patient empowerment, and a desire to be recognized for their role within the healthcare system.

Conclusion

There is still much to be investigated about massage therapists’ identity. Future research will explore whether this description resonates with a larger sample of massage therapists in Ontario.

The prevalence of the term subluxation in chiropractic degree program curricula throughout the world

Background

The subluxation construct generates debate within and outside the profession. The International Chiropractic Education Collaboration, comprised of 10 chiropractic programs outside of North America, stated they will only teach subluxation in a historical context. This research sought to determine how many chiropractic institutions worldwide still use the term in their curricula and to expand upon the previous work of Mirtz & and Perle.

Methods

Forty-six chiropractic programs, 18 United States (US) and 28 non-US, were identified from the World Federation of Chiropractic Educational Institutions list. Websites were searched by multiple researchers for curricular information September 2016–September 2017. Some data were not available on line, so email requests were made for additional information. Two institutions provided additional information. The total number of mentions of subluxation in course titles, technique course (Tech) descriptions, principles and practice (PP) descriptions, and other course descriptions were reported separately for US and non-US institutions. Means for each category were calculated. The number of course titles and descriptions using subluxation was divided by the total number of courses for each institution and reported as percentages.

Results

Means for use of subluxation by US institutions were: Total course titles = .44; Tech = 3.83; PP = 1.50; other = 1.16. For non-US institutions, means were: Total course titles = .07; Tech = .27; PP = .44; other = 0. The mean total number of mentions was 6.94 in US vs. 0.83 in non-US institutions. Similarly, the mean course descriptions was 6.50 in US vs. 0.72 in non-US institutions.

Conclusions

The term subluxation was found in all but two US course catalogues. The use of subluxation in US courses rose from a mean of 5.53 in 2011 to 6.50 in 2017. US institutions use the term significantly more frequently than non-US. Possible reasons for this were discussed. Unscientific terms and concepts should have no place in modern education, except perhaps in historical context. Unless these outdated concepts are rejected, the chiropractic profession and individual chiropractors will likely continue to face difficulties integrating with established health care systems and attaining cultural authority as experts in conservative neuro-musculoskeletal health care.
