The Neurophysiological Lesion: A Scoping Review

Objective

The purpose of this study was to examine the extent of the literature on the neurophysiological lesion as referenced in functional neurology.

Methods

A literature search was performed within the period from 2010 to March 2021. Search terms included central sensitization, central sensitivity syndrome, nociplastic pain, cold hyperalgesia, heat hyperalgesia, mechanical hyperalgesia, dynamic mechanical allodynia, temporal summation, spatial summation, and descending inhibition. A qualitative synthesis summarized the research findings, including clinical conditions and effect of spinal manipulation.

Results

There were 30 studies, which included 7 high-level studies (meta-analysis or systematic reviews), 22 randomized controlled studies, and 1 scoping review. The findings suggest the existence of the changes in the central integrated state of a population of neurons with various disorders, experimentally induced stimulation, and treatment. The current literature suggests plasticity of the central integrative state (CIS) with the onset of pathologies and the changes in the CIS with different conservative nonpharmacologic treatments.

Conclusions

This review suggests changes in the resting state of the CIS of a population of neurons that exist in the physiologic lesion may change in response to various therapies, including manipulative therapy. The findings from this review provide support of the hypothesis that nonpharmacologic conservative care may affect the neurophysiological lesion. However, studies were heterogeneous and evidence was lacking in the translation of targeting the therapies to distinct neuronal areas for clinical outcomes to treat specific disease states.

Chiropractic techniques and treatment modalities included in academic programs: A survey of chiropractic educational institutions

OBJECTIVE

The chiropractic techniques that chiropractors learn during their training strongly influence the nature of treatments provided by chiropractors and their professional identity. The objective of this project is to provide an exhaustive description of all chiropractic techniques and treatment modalities taught in chiropractic educational institutions.

METHODS

International experts were solicited to provide feedback on the exhaustivity and clarity of our preliminary questionnaire. Following the expert suggestions, we administered our cross-sectional survey representatives of all chiropractic education institutions listed on the World Federation of Chiropractic website. We also asked the contact information for an additional contact from each institution and surveyed them for triangulation purposes.

RESULTS

Among the 47 chiropractic education institutions surveyed, 29 completed our survey (response rate: 62%) of which 18 (62%) had 2 respondents. Among all the chiropractic techniques and treatment modalities investigated, only the Diversified technique was included in the core curriculum of all responding institutions. A considerable proportion of the techniques or modalities studied were not included in the educational activities of the institutions, particularly within the manual tonal or reflex techniques, instrument-assisted articular techniques, as well as the other techniques or modalities categories. Surprisingly, exercise prescription was not included in the core curriculum of all the institutions. Some scientifically challenged approaches were included in the educational activities of more than 40% of the institutions.

CONCLUSION

The portfolio of therapeutic teaching varies greatly between chiropractic educational institutions. A more standardized therapeutic curriculum could be beneficial to reduce public and interprofessional confusion toward therapeutic approaches in chiropractic.
