Abstract
Cervical spine surgery is a common neurosurgical procedure; however, postoperative pain remains a problem. This study aimed to examine the effectiveness of auricular acupressure, which is considered a noninvasive, convenient, and safe method for pain reduction and heart rate variability in patients after surgery. A total of 62 patients who underwent cervical spine surgery were randomly divided into experimental (32 patients) and control (30 patients) groups. Both groups received routine care, whereas the experimental group received auricular acupressure three times a day for four days. The Short-Form McGill Pain Questionnaire was administered, and heart rate variability measurements were obtained on the first, second, third, and fourth postoperative days. The results indicated that auricular acupressure was effective in reducing pain (P < .05) and improving heart rate variability (P < .05) in patients. Based on the findings, this study suggests that auricular acupressure can be used as a complementary treatment to reduce pain in patients after cervical spine surgery.

Autonomic nervous system and endocrine system response to upper or lower cervical spine mobilization in males with persistent post-concussion symptoms: a proof-of-concept trial. J Man Manip Ther 2024:1-17. [PMID: 38904298 DOI: 10.1080/10669817.2024.2363018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Accepted: 05/29/2024] [Indexed: 06/22/2024] Open
Abstract
INTRODUCTION The peripheral stress response, consisting of the autonomic nervous system (ANS) and hypothalamic pituitary adrenal-axis (HPA-axis), functions to maintain homeostasis in response to stressors. Cervical spine manual therapy has been shown to differentially modulate the stress response in healthy populations. No study has investigated whether cervical spine mobilizations can differentially modulate the stress response in individuals with persistent post-concussion symptoms (PPCS), a population characterized by a dysfunctional stress response. METHODS A randomized, controlled, parallel design trial was performed to investigate whether upper or lower cervical spine mobilization can differentially modulate components of the stress response in individuals with PPCS. The outcomes were salivary cortisol (sCOR) concentration (primary) and the HRV metric, rMSSD, measured with a smartphone application (secondary). Nineteen males diagnosed with PPCS, aged 19-35, were included. Participants were randomly assigned into either intervention group, upper (n = 10) or lower (n = 9) cervical spine mobilization. Each outcome was collected at different time points, pre- and post-intervention. Statistical analyses were performed using the Friedman's Two-Way ANOVA, Mann-Whitney U test, and Wilcoxon Signed Rank Test. RESULTS There was a statistically significant within-group reduction in sCOR concentration 30 minutes following lower cervical spine mobilizations and statistically significant within-group increase in rMSSD 30 minutes following upper cervical spine mobilizations. CONCLUSION The results of this trial provide preliminary evidence for cervical spine mobilizations to differentially modulate components of the stress response at specific time points. Understanding the mechanisms of the effect of cervical spine mobilizations on the stress response provides a novel rationale for selecting cervical spine mobilizations to rehabilitate individuals with PPCS.

The effectiveness of an osteopathic manual technique compared with a breathing exercise on vagal tone as indicated by heart rate variability, a crossover study. J Bodyw Mov Ther 2024; 38:449-453.

Abstract
INTRODUCTION Parasympathetic nervous system (PSNS) function can be inferred by heart rate variability (HRV) providing indications about an individual's health. Manual therapy may influence PSNS function, however the research outcomes in this regard are equivocal. This study explored the PSNS effect of a measured breathing technique with suboccipital balanced ligamentous tension, an osteopathic manipulative therapy technique. METHODS Healthy adult participants in this crossover study (n = 18) were randomly allocated into two groups with differing order of interventions. A 1:1 breathing rate of 6 breaths per minute maintained for 5 min was compared to the osteopathic intervention. HRV was measured for 5 min before and after each intervention and analysed using the root mean square of successive differences (RMSSD) between normal heartbeats and high frequency normalised units (HFnu). RESULTS The RMSSD data demonstrated no significant difference between groups or within groups (p > 0.05) over time. HFnu results showed a significant between-group difference over the four time points (p = 0.004) with a medium effect size (ηp2 = 0.240), and no significant within-group difference (p > 0.05). DISCUSSION The osteopathic intervention raised HRV to a small extent, however measured breathing lowered HRV. In the group that received the osteopathic technique first, HFnu values continued to rise post-osteopathic treatment possibly indicating an increasing parasympathetic effect over time. Recommendations for future studies include changing the breathing ratio to ensure parasympathetic response, take into account potential delayed effects of interventions, consider outcome measures less variable than HRV, and longer follow up times. CONCLUSION This study suggests parasympathetic stimulation may occur with the application of suboccipital balanced ligamentous tension and sympathetic stimulation from measured breathing.

Abstract
Cervicogenic headache (CGH) is a common condition affecting a significant portion of the population and is effectively managed through various interventions, including nonpharmacological approaches. Physical therapy plays a crucial role in CGH management, with numerous studies supporting its effectiveness. This systematic review aimed to evaluate the effectiveness of specific nonpharmacological physical therapy interventions for CGH. A comprehensive search was conducted across various databases (PubMed, Medline, PEDro, and Cochrane Library) for randomized controlled trials (RCTs) published between January 2017 and January 2023 investigating the effectiveness of specific nonpharmacological physical therapy interventions for CGH. We employed manual searches to capture potentially missed studies. Independent reviewers screened all studies based on predefined eligibility criteria. Extracted data included methodology, specific interventions, outcome measures (headache score, strength, pain, and quality of life (QOL)), and study conclusions. Eight RCTs were identified as meeting all inclusion criteria and were thus included in the data synthesis. The findings from these trials revealed a diverse range of nonpharmacological physical therapy interventions, including but not limited to manual therapy, exercise therapy, and multimodal approaches. Specifically, the interventions demonstrated significant improvements in headache scores, strength, pain levels, and overall QOL among individuals with CGH. These results underscore the multifaceted benefits of physical therapy in managing CGH and highlight its potential as a comprehensive treatment option. This review identified eight relevant RCTs investigating nonpharmacological interventions for CGH. Despite the promising findings, this review acknowledges several limitations, including the limited sample size and the heterogeneity of interventions across studies. These limitations emphasize the necessity for further research to elucidate optimal intervention strategies and refine treatment protocols. Nevertheless, the comprehensive analysis presented herein reinforces the pivotal role of physical therapy in not only alleviating pain but also enhancing function and improving the QOL for individuals suffering from CGH.

Abstract
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.

Abstract
This report describes a 42-year-old female patient who presented with an intensive nocturnal dry cough persisting for over six months. Subsequent to the prolonged cough, she developed shoulder and neck discomfort, leading her to seek chiropractic care. The patient received cervical chiropractic adjustments combined with the Koren Specific Technique (KST) emotions protocol. The patient was mainly treated for her musculoskeletal complaint. However, after two treatment sessions, the patient's chronic cough showed significant improvement. Two weeks later, the cough had completely ceased, and her shoulder and neck discomfort had also improved. The cough symptoms did not reappear during the six-month follow-up. The mechanism of cough improvement remains unclear, whether it is due to spinal adjustments, the KST emotions protocol, their combined effects, or merely a placebo response. This report discusses the potential underlying mechanisms of the case improvement, suggesting a non-pharmacological adjunctive therapeutic approach that could be investigated further in future research.

Abstract
There is a long-observed relationship between the pathology of the spine and arterial hypertension. There are a number of explanations for this, including one based on reflex effects and obstruction of blood flow to the cerebral vasodilatory centre localized in the rhomboid fossa projection. Obstruction can be absolute and relative, preventing the increase of blood flow during stress, when the brain turns on additional energy demand (phenomenon of «selfish brain»). In conditions of insufficient blood supply anaerobic metabolism is included, requiring in the future, the addition of anaerobic glycolysis products. This leads to the persistence of an elevated level of AD and is part of the theory of centralized compensation of aerobic-anaerobic balance (theoretical aerobic-anaerobic energy concept, TAAEBC). The existing methods of manual manipulation and physical action on the spine, mainly the atlantoacral section of the cervical spine, have, according to existing publications, varying degrees of effectiveness. The modern approach to treatment of arterial hypertension and correction of metabolic disorders by A. Shishonin is promising. It is based on the TAAEBC concept and assumes a system approach and long-term effect through a consistent three-step manual and physical interventions aimed at restoring, retaining and long-term support of the vertebral blood flow.

Abstract
BACKGROUND Cervical spine mobilizations may differentially modulate both components of the stress response, consisting of the autonomic nervous system and hypothalamic pituitary adrenal-axis, depending on whether the target location is the upper or lower cervical spine. To date, no study has investigated this. METHODS A randomized, crossover trial investigated the effects of upper versus lower cervical mobilization on both components of the stress response simultaneously. The primary outcome was salivary cortisol (sCOR) concentration. The secondary outcome was heart rate variability measured with a smartphone application. Twenty healthy males, aged 21-35, were included. Participants were randomly assigned to block-AB (upper then lower cervical mobilization, n = 10) or block-BA (lower than upper cervical mobilization, n = 10), separated by a one-week washout period. All interventions were performed in the same room (University clinic) under controlled conditions. Statistical analyses were performed with a Friedman's Two-Way ANOVA and Wilcoxon Signed Rank Test. RESULTS Within groups, sCOR concentration reduced thirty-minutes following lower cervical mobilization (p = 0.049). Between groups, sCOR concentration was different at thirty-minutes following the intervention (p = 0.018). CONCLUSION There was a statistically significant reduction in sCOR concentration following lower cervical spine mobilization, and between-group difference, 30 min following the intervention. This indicates that mobilizations applied to separate target locations within the cervical spine can differentially modulate the stress response.

Abstract
Objective The purpose of this case study was to describe the use of chiropractic care in the treatment of obstructive sleep apnea (OSA). Clinical Features A 42-year-old man with obesity presented for chiropractic care. He had OSA and was seeking a way to reduce snoring. The patient had a previous diagnosis of OSA and had been using a continuous positive airway pressure machine for over 5 years. The patient was a mouth breather, exhibiting poor oral and spinal posture. Intervention and Outcome The patient was treated for 90 days, which included chiropractic manipulation, orofacial myofunctional therapy exercises, nutritional modification, postural/ergonomic correction, and regular exercise. After a course of care, there was a drop in his apnea-hypopnea index from 55.4 events per hour to 3.4 events per hour. The patient lost 40 pounds, with an 8% reduction in body fat and an 8-point drop in his body mass index. Conclusion This patient's sleep apnea and other health outcomes improved under a course of a combination of chiropractic adjustments, orofacial myofunctional therapy, nutritional modification, postural/ergonomic correction, and exercise.

Abstract
BACKGROUND Physical interventions or manual therapeutic techniques (MTTe) such as mobilisation, manipulation or soft tissue techniques not only have an influence on the target tissue with improvement of metabolism or reduction of hypertonic muscles. They are also used for balance regulation in central nervous changes of the autonomic nervous system (ANS). To date, there is a lack of empirical evidence on impact mechanisms and target locations of MTTe on the ANS. This scoping review aims to provide an overview of the evidence on the application of MTTe at diverse levels of the spine with a view to the ANS. METHOD A systematic literature search was conducted on CENTRAL, Google Scholar, Osteopathic Research Web, PEDro and PubMed. The scope and content of the literature were documented. The results of the included and referenced studies were summarised in a narrative approach with the focus being on the most significant clinical aspects. RESULTS MTTe was described as manipulations, mobilisations, myofascial techniques and cervical traction. In 27 out of 35 studies, therapeutic treatments were carried out on healthy volunteers. Ten studies analysed immediate effects in patients, while two studies were designed as longitudinal studies in patients with hypertension. Over a period of four to eight weeks, the frequency of intervention was between one and three MTTe sessions a week. CONCLUSION The study results proved to be heterogeneous. For this reason, it is not possible to draw definitive, explicit and generally valid statements regarding the type and intensity as well as the segmental level at which MTTe should be applied in order to trigger specific positive ANS response mechanisms. Consequently, longitudinal studies with follow-up are recommended for future studies. In addition, comprehensive effects of MTTe should be evaluated in groups of patients with different characteristics.

Abstract
OBJECTIVE The objective of this study was to determine whether seated cervical manipulation produced changes in autonomic nervous system activity, as measured by heart rate variability and plasma norepinephrine levels. METHODS Ninety-five healthy young adults (ages 20-48 years) were recruited into a single-blinded physiological study, with 47 randomized to a seated cervical manipulation and 44 randomized to a sham procedure. Heart rate variability in the frequency domain, and plasma norepinephrine levels were measured prior to, immediately following, and 5 minutes following the intervention. RESULTS Electrocardiograms were obtained from 39 subjects in the sham group and 43 subjects in the manipulation group. No statistically significant changes were found in measures of heart rate variability in the frequency domain in either the manipulation or sham groups. Blood samples were obtained from 22 subjects in the sham group and 27 subjects in the manipulation group. Plasma norepinephrine levels, as measured by spectrophotometry, declined in both groups from pre- to immediately postintervention, and they remained at decreased levels 5 minutes after the interventions. There were no statistically significant differences between groups in pre- or postintervention norepinephrine levels. CONCLUSIONS Measures of heart rate variability and plasma norepinephrine levels did not show that seated cervical manipulation produced short-term changes in autonomic nervous system activity compared to a sham procedure in healthy young adults.

Abstract
BACKGROUND Neurological disorders are the leading cause of disability in the world. Neurological symptoms significantly affect the well-being of the individual. Spinal manipulative therapy (SMT) is a complementary method often used for people with neurological disorders. OBJECTIVE This study aimed to review the existing literature on the effects of SMT on common clinical symptoms of neurologic disorders and the quality of life. METHODS Narrative review was conducted through the literature published between January 2000 and April 2020 in English. The search was performed across four databases: PubMed, Google Scholar, PEDro, and Index to Chiropractic Literature. We used combinations of keywords related to SMT, neurological symptoms, and quality of life. Studies on both symptomatic and asymptomatic populations of different ages were included. RESULTS 35 articles were selected. Evidence for the administration of SMT for neurological symptoms is insufficient and sparse. Most studies focused on the effects of SMT on pain, revealing its benefits for spinal pain. SMT may increase strength in asymptomatic people and populations with spinal pain and stroke. SMT was reported to affect spasticity, muscle stiffness, motor function, autonomic function, and balance problems, but these studies were limited in number to make conclusions. An important finding was the positive influence of SMT on the quality of life in people with spinal pain, balance impairments, and cerebral palsy. CONCLUSION SMT may be beneficial for the symptomatic treatment of neurological disorders. SMT can positively affect the quality of life. However, limited evidence is available, and further high-quality research is required.

Abstract
OBJECTIVE The purpose of this study was to identify sources and strategies for the mitigation of bias in studies of spinal manipulation and heart rate variability. METHODS A small-scale study compared the effects of a single session of sham and authentic cervical manipulation on heart rate variability as measured by power spectrum analysis. The participants were a sample of 31 healthy young students from the Canadian Memorial Chiropractic College, randomized into 2 study arms. The effectiveness of blinding was evaluated, and 2 alternative methods of data analysis were explored to mitigate risk of bias. Following execution of the study, the stages of implementation and data processing were scored against version 2 of the Cochrane risk-of-bias tool for randomized trials for risk of bias. RESULTS The risk of bias arising from (1) the randomization process, (2) missing outcome data, and (3) selection of reported results was judged to be low. Risk of bias in (1) deviations from intended interventions (particularly due to the failure of masking) and (2) the measurement of the outcome, for example, through cleaning of the data, were judged to be high. CONCLUSION The use of power spectrum analysis of heart rate variability based on 5-minute recordings of echocardiogram pre-and post-intervention contained multiple sources of bias that were challenging to mitigate. Based upon these findings, power spectrum analysis of heart rate variability using these parameters may be ill-suited to the study of physiological effects of spinal manipulative therapy.

Abstract
STUDY DESIGN Three-arm, parallel, randomized, placebo-controlled, assessor-blinded trial. OBJECTIVE To compare the immediate effect of manual therapy at the upper thoracic spine on the cardiovascular autonomic control of patients with musculoskeletal pain. SUMMARY OF BACKGROUND DATA Musculoskeletal pain increases the risk of cardiovascular events. Thus, manual therapy applied to the upper thoracic region is likely efficient to improve the cardiac autonomic control. METHODS The study included 59 patients with musculoskeletal pain enrolled at an outpatient clinic. Participants were randomly assigned to spinal manipulation (n = 19), myofascial manipulation (n = 20), or placebo (n = 20) administered to the upper thoracic region. Resting heart rate variability provided indexes of the cardiac autonomic control, and the blood pressure response to the cold pressor test as a proxy of the sympathetic responsiveness to a stressor stimulus. RESULTS Groups were similar for baseline variables except for blood pressure. Two-way repeated-measures one-way analysis of covariance (ANCOVA) revealed that only spinal manipulation induced immediate increase of the square root of the mean squared differences of successive RR intervals (RMSSD), absolute (ms2), and normalized units (n.u.) of the high-frequency power (HF) as compared with pre-intervention evaluation, indicating an improvement in the parasympathetic activity to the heart. Normalized units of low-frequency power (LF) and the LF/HF ratio reduced after the spinal manipulation solely, suggesting a reduction of the sympathetic activity to the heart. There were no significant differences in the blood pressure responsiveness among the three treatments. There were no adverse events. CONCLUSION In patients with musculoskeletal pain, spinal manipulation on the upper thoracic spine led to an immediate improvement in the resting cardiac autonomic control without an effect on the blood pressure responsiveness to a sympathoexcitatory stimulus. Myofascial manipulation or placebo did not change cardiovascular autonomic control.Level of Evidence: 2.

Abstract
OBJECTIVE The purpose of this study was to investigate the effects of osteopathic manipulative treatment (OMT) on cardiovascular autonomic parameters after a rugby match. METHODS Resting and reactivity (ie, response to orthostasis) measures of mean arterial pressure, heart rate, and heart rate variability were assessed in 23 male players after a single session of OMT, both 18 to 20 hours after a rugby match and in a corresponding no-match condition, in a randomized, sham-controlled, crossover design. RESULTS Signs of reduced heart rate variability and elevated mean arterial pressure and heart rate were found 18 to 20 hours after a rugby match compared with the no-match condition. A significant increase in heart rate variability and a significant reduction in mean arterial pressure were observed after OMT in both the after-match and no-match conditions. Heart rate and heart rate variability responses to orthostasis were not affected by previous match competition, but were significantly larger after OMT compared with sham treatment. CONCLUSION This study suggests the presence of cardiovascular autonomic alterations in rugby players after a competitive match, which may be indicative of prolonged fatigue and incomplete recovery. In these players, favorable changes in cardiovascular autonomic parameters were observed following a single session of OMT.

Abstract
BACKGROUND AND AIM Hypertension is a multifactorial condition that is among the leading causes of mortality worldwide. Regulation of blood pressure greatly depends upon the activity of the autonomic nervous system. Alterations in the autonomic nervous system can lead to hypertension. In addition to nervous system control and individual physiologic state, various genes can directly influence autonomic responses. The complexity of blood pressure control is reflected in the 20-30% of individuals resistant to traditional pharmacological treatment, this indicates the need for alternative interventions. This article provides an integrative review and discussion of the key neurophysiologic and genetic factors that contribute to blood pressure regulation, the autonomic nervous system (ANS) and manual therapy literature, and the manual therapy and blood pressure literature. METHODS To assess the effects of chiropractic on the management of hypertension we searched articles published from 1980 to 2019 in PubMed, the Index to Chiropractic Literature and CINAHL, using the keywords: chiropractic, spinal manipulation, hypertension, and blood pressure. RESULTS We found 38 original studies that analyzed the effect of chiropractic therapy on hypertension. Of these studies, 10 were case reports and the statistical significance of the effects of chiropractic on blood pressure was not evaluated on these articles, so we focused on the remaining 28 articles. CONCLUSIONS The results of the review relative to chiropractic care were promising, but often contradictory, suggesting more research should be done. In consideration of the complexity of ANS blood pressure control, an evaluation of patient presenting physiologic and genetic characteristics is recommended and could provide valuable insight relative to the likelihood of patient blood pressure related responsiveness to care.

Abstract
Background: Spinal pain or misalignment is a very common disorder affecting a significant number of populations resulting in substantial disability and economic burden. Various manual therapeutic techniques such as spinal manipulations and mobilizations can be used to treat and manage pain and movement dysfunctions such as spinal mal-alignments and associated complications. These manual therapeutic techniques can affect the cardiovascular parameters.Objective: The objective of this systematic review and meta-analysis is to assess the effect of spinal manipulation and mobilization on cardiovascular parameters.Methods: We conducted a systematic review and meta-analysis to assess the effects of spinal mobilization and manipulation on cardiovascular responses. Mean changes in Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and Heart Rate (HR) were primary outcome measures. RevMan 5.3 software was used for the meta-analyses. Quality of the included studies was assessed by PEDro Rating scale. Risk of bias was assessed by Cochrane collaboration tool of risk of bias.Results: Results of meta-analysis showed that there was statistically significant decrease in SBP ([Formula: see text], 95% [Formula: see text], 0.08; [Formula: see text]) with moderate heterogeneity ([Formula: see text], [Formula: see text]) in experimental group as compared to control group. There was statistically non-significant decrease in DBP ([Formula: see text], 95% [Formula: see text], 0.69; [Formula: see text]) with high heterogeneity ([Formula: see text], [Formula: see text]), Change HR was statistically non-significant ([Formula: see text], 95% [Formula: see text], 3.11; [Formula: see text]) with moderate heterogeneity ([Formula: see text], [Formula: see text]). Exclusion of short duration studies in sensitivity analysis revealed a statistically significant change in DBP ([Formula: see text], 95% [Formula: see text], [Formula: see text]; [Formula: see text]). However, the result was statistically non-significant for HR after sensitivity analysis.Conclusion: Spinal manipulations and mobilizations may result in significant decrease of systolic as well as diastolic Blood Pressure.

Abstract
STUDY DESIGN A secondary analysis of a systematic review. BACKGROUND Manipulations or mobilizations are commonly used interventions in patients with mechanical neck pain. The treatment effects have often been studied in randomized controlled trials (RCT) which are generally considered the gold standard in evaluating the treatment effects, mainly due to its high internal validity. External validity is defined as the extent to which the effects can be generalised to clinical practice. An important prerequisite for this is that interventions used in clinical trials can be replicated in clinical practice. It can be questioned if interventions utilized in randomized controlled trials can be translated into clinical practice. OBJECTIVES The overall aim of this study is to examine whether the quality of the description of manipulation and mobilization interventions is sufficient for to replication of these interventions in clinical practice. METHODS A comprehensive literature search was performed. Two independent researchers used the Template for Intervention Description and Replication (TIDieR) which is a 12-item checklist for describing the completeness of the interventions. RESULTS Sixty-seven articles were included that used manipulation and/or mobilization interventions for patients with mechanical neck pain. None of the articles describe the intervention e.g. all the items on the TIDieR list. Considering item 8 (a-f) of the TIDieR checklist only one article described the used techniques completely. CONCLUSION Manipulation or a mobilization interventions are poorly reported in RCTs, which jeopardize the external validity of RCTs, making it difficult for clinicians and researchers to replicate these interventions.

Abstract
OBJECTIVE The objective of this systematic review was to evaluate the effectiveness of an osteopathic treatment on the autonomic nervous system (ANS). For this purpose, published primary studies were analysed and critically evaluated. METHOD To generate this review, 15 electronic databases were systematically searched for studies. Randomized clinical controlled trials (RCT) and clinical controlled trials (CCT) are included in the review and evaluated with appropriate assessment tools (Downs and Black Checklist and the checklist from Kienle and Kiene). RESULTS 23 published studies (10 RCT, 1 clinic multi-centre study, 1 CCT, 5 randomized cross-over studies, 5 randomized pilot studies and 1 single case study) are included in this review. The studies were evaluated with the assessment tools according to their quality. 3 studies are graded as high quality, 11 as moderate and 8 as low-quality studies. CONCLUSION The included published studies represent a good level of evidence. Due to a small number of subjects and no follow-ups, the methodological quality is rated as moderate. A significant change on the ANS was shown in studies including High-Velocity Low-Amplitude Techniques (HVLAT). No statement could be drawn in studies in which they used cranial osteopathic techniques due to the lack of methodological quality. A significant change on the ANS is shown in the treatment of the suboccipital region. In studies which evaluated the effectiveness of mobilization in the cervical and thoracic region, no statement could be displayed due to a low level of evidence. None of the findings in these studies have given statements if ANS activation takes place in the sympathetic or parasympathetic system.

Abstract
STUDY DESIGN Systematic review. OBJECTIVE To summarize the evidence of neurophysiological effects of spinal manipulative therapy (SMT) with a high velocity low amplitude thrust (HVLA-SMT) in asymptomatic and symptomatic humans. SUMMARY OF BACKGROUND DATA HVLA-SMT is effective in reducing back pain, but its mode of action is not fully understood. METHODS A systematic literature search (until July 2018) was conducted by a professional librarian in seven databases (Medline (OvidSP), Premedline (PubMed), EMBASE, Cochrane, CINAHL, PEDro, and Scopus). Two authors selected the studies according to the a priori described criteria and scored study quality. Only controlled studies of at least moderate quality were included. Effects of HVLA-SMT on a particular outcome measure were defined as more than one study showing a significantly greater effect of HVLA-SMT compared with the control intervention. RESULTS From the 18 studies included (932 participants in total), there was evidence only for an association between HVLA-SMT and changes in the autonomic nervous system, reflected in changes in heart rate variability and skin conductance. Most studies focused on healthy volunteers and none related neurophysiologic changes to pain reduction. CONCLUSION This systematic review points to HVLA-SMT affecting the autonomic nervous system. The effects seem to depend on the spinal level of HVLA-SMT application and might differ between healthy volunteers and pain patients. There is a need for high-quality studies that include patients, well characterized for pain duration and outcome measure baseline values, and address the relation between changes in neurophysiology and pain.

Abstract
BACKGROUND sympathoexcitation observed with passive cervical mobilisations may imply activation of an endogenous pain inhibition system resulting in hypoalgesia. However, research is mostly in asymptomatic participants and there is very limited evidence of a relationship between sympathoexcitation and symptomatic improvement in people with clinical pain. OBJECTIVE to investigate the effects of cervical mobilisations on the sympathetic nervous system in participants with neck pain, and to explore the relationship between symptomatic improvement and sympathoexcitation. DESIGN double-blind randomised controlled trial. METHOD 40 participants with neck pain (aged 20-69 years, 25 female) were randomly allocated to either cervical mobilisations or motionless placebo. Skin conductance was measured before, during, and after intervention. After interventions were completed, their credibility was assessed. Participants were classified as responders or non-responders according to global symptom change. RESULTS participants receiving mobilisations were more likely to be classified as responders (odds ratio: 4.33, p = 0.03) and demonstrated greater change in most outcome measures of sympathoexcitation from baseline to during the intervention but not from during to after the intervention. There was no association between sympathoexcitation and symptomatic improvement. Mobilisations and placebo were equally credible. CONCLUSIONS These findings suggest sympathoexcitatory changes may be caused by an orienting response unrelated to the activation of an endogenous pain inhibition system Alternatively, the observed lack of an association may be explained by the existence of various mechanisms for pain relief. This study used single outcome measures of sympathoexcitation and symptomatic improvement and other measures may reveal different things. CLINICALTRIALS. GOV NUMBER M10/2016/095.

Abstract
OBJECTIVE The purpose of this study was to correlate the heart rate variability (HRV) indices with variables of pain that were experienced by individuals with chronic neck pain. METHODS This was a blinded cross-sectional study. Individuals with chronic neck pain (n = 15) and healthy participants (n = 15), both sedentary and between 18 and 45 years of age, were included. The neck pain was assessed with the Numerical Rating Scale at rest and during cervical movements, Neck Disability Index, Catastrophic Thoughts about Pain Scale, and Tampa Scale of Kinesiophobia. The HRV indices (linear and nonlinear) were used for assessment of autonomic function at rest (in supine, sitting, and standing positions). RESULTS We observed significant correlations between the NRS, Neck Disability Index, and Catastrophic Thoughts about Pain Scale with the linear and nonlinear HRV indices (P < .05, r ≥ 0.362), so that the worst HRV indices are associated with conditions of more intense and disabling neck pain. CONCLUSION The HRV indices were significantly associated with pain intensity, disabilty, and catastrophizing in individuals with chronic neck pain.

Abstract
INTRODUCTION Pulse pressure is an indicator of cardiovascular health and is the difference between systolic and diastolic blood pressures. An important etiologic consideration is autonomic nervous system balance. The purpose of this study is to observe pulse pressure changes following a six-week course of care utilizing an upper cervical technique. METHODS One hundred and thirty patients presenting in five different clinics were separated into three groups based on initial pulse pressure groups with 40 mmHg considered as normal: low (< 40 mmHg), medium (40-49 mmHg), and high (> 49 mmHg). RESULTS Pulse pressure reduced by 8.9 mmHg in the high group which was statistically significant (p < 0.01) with a large effects size of 0.8. Changes in the low and medium groups were not statistically significant (p < 0.05). CONCLUSION In this observational study the group displaying the highest pulse pressure demonstrated statistically significant reduction in pulse pressure.

Abstract
Background The autonomic nervous system (ANS) interests many chiropractors and manual therapists, because joint manipulative techniques (JMT), e.g. high velocity low amplitude (HVLA) manipulations and mobilizations, appear to produce acute changes in ANS mediated physiology. The complexity of this issue justifies a systematic critical literature review. Objective To review the literature comparing the acute changes in markers of ANS activity between JMT applied on spinal or peripheral joints and a sham procedure in healthy or symptomatic subjects. Method We searched PsycINFO, PEDro, PubMed, Cochrane library, EMBASE, and Medline up to December 2017. We updated the search with PubMed, Cochrane library, EMBASE, and Medline including July 2018. Inclusion criteria were: randomized sham-controlled trials assessing the effect of JMT on markers of ANS activity; manually applied JMT, regardless of technique, applied on either healthy or symptomatic humans; outcome measurements recorded at baseline and repeated during and/or after interventions. Selection of articles and data extraction were performed independently by two reviewers. The quality of studies was assessed using the Cochrane ‘risk of bias’ tool and a technical check-list. Results were reported narratively with some meta-analyses. The Cochrane GRADE approach was used to assess the certainty of evidence. Results Twenty-nine of 2267 studies were included in the synthesis. Mobilizations (oscillatory technique) probably produce an immediate and short-term, bilateral increase in skin sympathetic nerve activity (reflected by an increase in skin conductance) regardless of the area treated (moderate-certainty evidence). It is uncertain whether the sympathetic arousal also explains an increase in respiratory rate (very low-certainty evidence). Our evaluation of the literature suggests that spinal sustained apophyseal glides (SNAGs) mobilization and HVLA manipulation of the spine may have no acute effect on the studied markers of ANS activity (very low- to low-certainty evidence). Conclusion Some types of mobilizations probably produce an immediate and short-term, statistically significant increase in skin sympathetic nerve activity when compared to a sham procedure, whereas spinal SNAGs and spinal HVLA techniques may have no acute effect on the studied markers of ANS activity. No region-specific results were noted. The literature suffers from several shortcomings, for which reason we strongly suggest further research.

Abstract
We report the case of a 44-year-old school teacher who experienced long-term relief from tension-type headache (TTH) and major depression following chiropractic treatment. It is well recognized that psychiatric comorbidity and suicide risk are commonly found in patients with painful physical symptoms such as chronic headache, backache, or joint pain. Recent studies indicated that autonomic dysfunction plays a role in the pathogenesis of TTHs and depressive disorders. The autonomic nervous system is mainly controlled by reflex centers located in the spinal cord, brain stem, and hypothalamus. This report highlights the rewarding outcomes from spinal adjustment in certain neuropsychiatric disorders. Long-term results of chiropractic adjustment in this particular case were very favorable. Further studies with larger groups are warranted to better clarify the role of chiropractic.

Cohen DJ, Schulman S, Masarsky CS, Todres-Masarsky M. The Kaleidoscope Model of Integrative Healthcare as a collaborative paradigm for cardiology and chiropractic: a call to action. Integr Med Res 2018; 7:1-8. [PMID: 29629286 PMCID: PMC5884005 DOI: 10.1016/j.imr.2018.01.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2017] [Revised: 01/17/2018] [Accepted: 01/24/2018] [Indexed: 11/28/2022] Open
Abstract
This review article proposes a model of integrative care for cardiovascular patients in institutional settings. We review relevant historic and contemporary examples of medical-chiropractic cooperation and a brief review of the literature illustrating the clinical benefits of chiropractic care for patients with cardiovascular disease. The groundwork proposes a distinct research and clinical practice model incorporating the doctor of chiropractic (D.C.) as a synergistic partner with the medical cardiologist coined the Kaleidoscope Model of Integrative Care (KM). While a traditional kaleidoscope does not alter the nature of light itself, the observer does see the 'raw data' of colors and shapes, wavelengths, etc. contained within the "potential" of the light itself; left unrecognized, even subtle re-orientations of the instrument changes the perspective. Similarly, the KM is intended as a conduit for slight reorientations to traditional medical-chiropractic-patient hierarchies, thus creating new treatment options and generating robust changes in inter-professional perception of the patient's condition(s) and treatment options. It is hoped that this model will not only serve future patients within hospitals, but that institutions will serve as incubators for better collaboration and research among the majority of free-standing medical and chiropractic practices ultimately benefitting the patient with cardiovascular disease.

Atlantoaxial Misalignment Causes High Blood Pressure in Rats: A Novel Hypertension Model. BIOMED RESEARCH INTERNATIONAL 2017; 2017:5986957. [PMID: 28791307 PMCID: PMC5534292 DOI: 10.1155/2017/5986957] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/10/2017] [Revised: 05/30/2017] [Accepted: 06/07/2017] [Indexed: 02/08/2023]
Abstract
Atlantoaxial disorders are often correlated with hypertension in practice. In order to study the relationship between atlantoaxial disorder and hypertension, we attempted to construct an animal model. In this work, we presented an animal model where their atlantoaxial joints were misaligned. We investigated the changes of blood pressure before and after treatments of the modeled rats. We had the following results. (1) SBP and DBP of each surgery group were significantly higher than those of control and sham groups. (2) After the second operation (the fixture was removed), SBP and DBP of both surgery groups decreased and got closer to the control and sham groups after 7 days. (3) Heart rates got significantly higher in both surgery groups, compared to control and sham groups. (4) The blood Ach levels of the surgery groups were significantly lower than those of control and sham groups. With these results, we concluded that we successfully constructed cervical atlantoaxial disorder models in rats that showed hypertension symptom. However, the underlying mechanism connecting atlantoaxial disorder and hypertension still requires further study.

Changes in Muscle Spasticity in Patients With Cerebral Palsy After Spinal Manipulation: Case Series. J Chiropr Med 2016; 15:299-304. [PMID: 27857638 DOI: 10.1016/j.jcm.2016.07.003] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2016] [Revised: 06/24/2016] [Accepted: 07/31/2016] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVE The purpose of this case series was to report quantitative changes in wrist muscle spasticity in children with cerebral palsy after 1 spinal manipulation (SM) and a 2-week course of treatment. METHODS Twenty-nine patients, aged 7 to 18 years, with spastic forms of cerebral palsy and without fixed contracture of the wrist, were evaluated before initiation of treatment, after 1 SM, and at the end of a 2-week course of treatment. Along with daily SM, the program included physical therapy, massage, reflexotherapy, extremity joint mobilization, mechanotherapy, and rehabilitation computer games for 3 to 4 hours' duration. Spasticity of the wrist flexor was measured quantitatively using a Neuroflexor device, which calculates the neural component (NC) of muscle tone, representing true spasticity, and excluding nonneural components, caused by altered muscle properties: elasticity and viscosity. RESULTS Substantial decrease in spasticity was noted in all patient groups after SM. The average NC values decreased by 1.65 newtons (from 7.6 ± 6.2 to 5.9 ± 6.5) after 1 SM. Another slight decrease of 0.5 newtons was noted after a 2-week course of treatment. In the group of patients with minimal spasticity, the decrease in NC after the first SM was almost twofold-from 3.93 ± 2.9 to 2.01 ± 1.0. In cases of moderate spasticity, NC reduction was noted only after the 2-week course of intensive treatment. CONCLUSIONS In this sample of patients with cerebral palsy, a decrease in wrist muscle spasticity was noted after SM. Spasticity reduction was potentiated during the 2-week course of treatment.
