Effectiveness of osteopathic interventions in chronic non-specific low back pain: A systematic review and meta-analysis

An overview of systematic reviews on the efficacy and safety of osteopathic techniques

OBJECTIVE

To investigate the efficacy and safety of manipulative osteopathic techniques in persons of all ages with various medical indications.

DESIGN

Overview of systematic reviews and meta-analyses.

METHOD

We conducted a systematic literature search for systematic reviews of randomized controlled trials in English or German that compared osteopathic interventions to no treatment, sham treatment or any other non-osteopathic treatment, in bibliographic databases and other sources.

RESULTS

We included 27 systematic reviews covering nine therapeutic indications. Based on moderate quality of evidence, osteopathic treatment was an effective means of reducing pain and partially improving physical function in adults with acute neck pain, chronic non-specific low back pain, low back pain in pregnancy, and chronic non-oncologic pain. It can also shorten the length of hospital stays in premature infants. Furthermore, osteopathic treatment may relieve symptoms in adults with chronic neck pain, postpartum low back pain, migraine, and irritable bowel syndrome, and it may help children with otitis media. It did not appear to provide relief to adults with acute non-specific low back pain, fibromyalgia, headaches of various causes, women with lower urinary tract symptoms, and children with cerebral palsy. Evidence for other indications like vertigo, chronic obstructive pulmonary disease, hypertension, gynecological or birth-related complaints, and a number of pediatric indications was insufficient to draw firm conclusions.

CONCLUSION

Manipulative osteopathic techniques appears to be particularly effective in musculoskeletal conditions. Overall, the evidence base for the outcomes of manual osteopathic treatment has improved, despite heterogeneous studies that are partly of poor methodological quality.

Osteopathic diagnosis and treatment of the spine in patients with chronic back pain through the lens of medical infrared thermography: A randomized controlled pilot study

BACKGROUND AND PURPOSE

Chronic back pain conditions are highly prevalent worldwide. Osteopathic treatment seems to improve pain and function in this population. However, the mechanisms underlying osteopathic diagnosis and treatment of the spine are mainly unknown. Arguably, both inflammatory and autonomic processes may be involved, which should entail changes in skin temperature. Primarily, the feasibility of the study protocol was evaluated by assessing the retention, adherence, acceptability, safety, and blinding concealment rates and carrying out a power analysis. Secondarily, we investigated diagnostic correlations between pain ratings, palpatory findings, and skin temperature in spinal segments and therapeutic effects of osteopathic and sham spine manipulations.

MATERIALS AND METHODS

In this single-blinded, randomized, and sham-controlled pilot and feasibility study, participants with chronic back pain were randomly allocated (1:1 ratio) to receive a single session of osteopathic or sham spine manipulations. Manual diagnosis, pain assessment, and infrared imaging were performed before treatment (baseline) and one week after treatment (follow-up), whereas infrared imaging was additionally conducted shortly after treatment (post-intervention).

RESULTS

Seventeen participants completed the trial with 89.5 % retention, 100 % adherence, 100 % acceptability, 6 % adverse events, 22 % (osteopathic) and 50 % (sham) blinding concealment. A power analysis estimated a sample of 40 subjects for future randomized controlled trials. At baseline, no significant correlations were detected between palpatory findings, pain ratings, and skin temperature. There were no significant between-group differences in palpatory findings at single time points and pain ratings across time points (p < 0.05), whereas skin temperature showed significant between-group differences across all time points (p < 0.01). At post-intervention, osteopathic spine manipulations increased the skin temperature with a medium effect (Cohen's d = 0.66).

CONCLUSION

The study was feasible. Osteopathic diagnosis does not seem to correlate with pain ratings and skin temperature. However, the increase in skin temperature shortly after osteopathic treatment suggests an autonomic (hyper-parasympathetic) effect.

The role of osteopathic manipulative treatment for dystonia: a literature review

CONTEXT

Dystonia is a movement disorder that causes involuntary muscle contractions leading to abnormal movements and postures, such as twisting. Dystonia is the third most common movement disorder in the United States, with as many as 250,000 people affected. Because of its complexity, dystonia presents a significant challenge in terms of management and treatment. Despite limited research, osteopathic manipulative treatment (OMT) has been considered as an adjunctive treatment due to its inexpensive and noninvasive nature, as opposed to other modalities such as botulinum toxin injections, deep brain stimulation (DBS), and transcranial magnetic stimulation, which are often expensive and inaccessible. OMT treatments performed in case studies and series such as balanced ligamentous tension/articular ligamentous strain (BLT/ALS), muscle energy (ME), high-velocity low-amplitude (HVLA), and myofascial release (MFR) have shown reduction of pain and muscle hypertonicity, including in patients with dystonia.

OBJECTIVES

The studies reviewed in this paper provide a snapshot of the literature regarding the current evidence of OMT's role for dystonia.

METHODS

A medical reference librarian conducted a thorough literature search across multiple databases including PubMed and Google Scholar to find articles relevant to the use of OMT for dystonia. The search employed a combination of Medical Subject Headings (MeSH) terms and keywords related to osteopathic medicine and dystonia to ensure precise retrieval of relevant articles within the last 20 years. Despite limited research on the topic, all four relevant reports found in the literature were selected for review.

RESULTS

Of the four relevant reports, case series and studies highlighted the potential benefits of OMT in managing dystonia, particularly cervical dystonia and foot dystonia. OMT has shown promising results addressing pain, stiffness, and impaired motor function. In cases of foot dystonia in Parkinson's disease, OMT has helped improve gait and reduce pain by targeting somatic dysfunctions (SDs) associated with dystonia, such as abnormalities in foot progression angle (FPA) and musculoskeletal imbalances. Also, OMT has been found to alleviate symptoms of cervical dystonia, including tremors, muscle spasms, and neck stiffness. These interventions performed in case studies and series led to improvements in gait biomechanics in foot dystonia and overall symptom severity in patients with cervical dystonia.

CONCLUSIONS

Currently, botulinum toxin, oral medications, physical therapy, and rehabilitation are commonly utilized in managing dystonia. The studies reviewed in this paper suggest that these treatments may lead to improvements in pain and muscle hypertonicity in patients with dystonia. It is important to investigate whether factors such as the type of dystonia (eg, focal vs. segmental) and its underlying cause (eg, idiopathic, trauma, infection, autoimmune, medication side effects) influence treatment outcomes. Further research is recommended to explore the role of OMT in managing dystonia.

A national survey of osteopaths' conceptions of practice in France: structural validity of the Osteo-TAQfr and the tendency toward technical rationality

BACKGROUND

Despite the growing popularity of osteopathy in France, little is known about how French osteopaths conceptualise key aspects of their practice, including skills, knowledge, and decision-making. This study aimed to adapt and validate the Osteopaths' Therapeutic Approaches Questionnaire (Osteo-TAQ) for use in a French osteopathic population (Osteo-TAQfr) and to examine the professional profile and core elements of clinical practice among French osteopaths. The first objective was to establish the psychometric properties of the Osteo-TAQfr within a French osteopathic population. The second aim was to explore French osteopaths' conceptions of practice and their approach to patient care, thereby contributing to a broader understanding of the profession in France and its relevance within the discourse on allied health professions (AHPs).

METHODS

A cross-sectional study was conducted to (1) adapt and validate the French version of the Osteopaths' Therapeutic Approaches Questionnaire (Osteo-TAQfr) and (2) explore osteopaths' conceptions of practice in France. The translation and cultural adaptation process was informed by cognitive interviews to ensure linguistic and contextual appropriateness. Exploratory Factor Analysis (EFA) was performed to assess the factor structure in the French osteopathic context and Confirmatory Factor Analysis (CFA) was used to test the validity of previously established constructs-Professional Artistry (PA) and Technical Rationality (TR). Internal consistency was evaluated using McDonald's omega (ω).

RESULTS

The survey yielded 1,703 complete responses. Analysis supported a two-factor model with PA andTR subscales, both showing strong reliability estimations (PA ω = 0.882; TR ω = 0.873). Minor theory-informed adjustments improved model fit. A moderate negative correlation was observed between the PA and TR subscales (r=-0.407). Respondents with additional health professions qualifications scored lower on the PA subscale and higher on the TR subscale.

CONCLUSIONS

The Osteo-TAQfr is an original tool that assesses conceptions of osteopathic practice in France. Findings reveal a predominance of TR among French osteopaths, characterised by biomedical, technique-driven approaches. These results have significant implications for aligning osteopathic education and practice with contemporary AHP paradigms, including patient-centred care and interdisciplinary collaboration. Further research should explore the transferability of the Osteo-TAQ across other healthcare systems and its potential impact on clinical outcomes and professional development.

"The Dark Side of Musculoskeletal Care": Why Do Ineffective Techniques Seem to Work? A Comprehensive Review of Complementary and Alternative Therapies

The increasing interest in complementary and alternative medicines (CAMs) for musculoskeletal care has sparked significant debate, particularly regarding their biological plausibility and clinical effectiveness. This comprehensive review critically examines the use of two of the most widely utilized CAMs-osteopathy and chiropractic care-over the past 25 years, focusing on their biological plausibility, clinical effectiveness, and potential mechanisms of action. Our analysis of current research and clinical studies reveals that osteopathy and chiropractic are based on concepts such as "somatic dysfunction" and "vertebral subluxation", which lack robust empirical validation. While these therapies are often presented as credible treatment options, studies evaluating their effectiveness frequently exhibit serious methodological flaws, providing insufficient empirical support for their recommendation as first-line treatments for musculoskeletal conditions. The effects and mechanisms underlying osteopathy and chiropractic remain poorly understood. However, placebo responses-mediated by the interaction of contextual, psychological, and non-specific factors-appear to play a significant role in observed outcomes. The integration of therapies with limited biological plausibility, whose effects may primarily rely on placebo effects, into healthcare systems raises important ethical dilemmas. This review highlights the need for rigorous adherence to scientific principles and calls for a more comprehensive investigation into biobehavioral, contextual, and psychosocial factors that interact with the specific effects of these interventions. Such efforts are essential to advancing our understanding of CAMs, enhancing clinical decision-making, promoting ethical practices, and guiding future research aimed at improving patient care in musculoskeletal disorders.

Why do physicians practice osteopathic manipulative treatment (OMT)? A survey study

CONTEXT

Few osteopathic physicians (Doctors of Osteopathic Medicine [DOs]) utilize osteopathic manipulative treatment (OMT) in their clinical practice, although all DOs are trained to do so. The reasons why many do not utilize OMT are not entirely clear. Anecdotally, these authors have observed that if a physician utilizes OMT, it is because they witnessed the efficacy for themselves in real-life clinical diagnoses found on patients or volunteers. This study seeks to explore this phenomenon.

OBJECTIVES

This study seeks to explore the relationship between witnessing the efficacy of OMT and the future use of OMT in clinical practice.

METHODS

Surveys were sent to DOs who work with Des Moines University's College of Osteopathic Medicine (COM) clinical students as well as osteopathic medical students enrolled at the Des Moines University's COM. Survey data were analyzed by separating physicians into cohorts based on their use of OMT and students into cohorts based on their interest in utilizing OMT in future practice.

RESULTS

DOs who practice OMT reported at least one, and often multiple, instances of witnessing the efficacy of OMT on real-life patients or volunteers while in their first 2 years of medical school. Those who do not utilize OMT reported few opportunities to witness the efficacy of OMT on a real-life patient. For physicians, 96.1 % of those who utilize OMT in their practice had the opportunity to see it work positively during the first 2 years of medical school, whereas only 7.4 % who do not utilize OMT had the opportunity. These findings are mirrored in the experience of current osteopathic medical students who are interested and uninterested in utilizing OMT in their future practice.

CONCLUSIONS

These findings emphasize the importance of exposing our medical students to some type of 'real-life' experience early in their careers; the data show that these experiences can be very beneficial in expanding the interest in utilizing osteopathic manipulative medicine (OMM) in future practice. COMs can consider the implementation of programs that provide this experience to students, including extracurricular activities dedicated to the use of OMT.

A Longitudinal, Observational, and Descriptive Study About Benefits of Craniosacral Therapy in Child Neurodevelopment

INTRODUCTION

Coordination and balance are progressive motor skills that guide physical therapists in recognizing abnormal patterns during childish neurodevelopment. We aim to compare the efficacy of craniosacral therapy (CST) together with balance and coordination therapy (BCT) vs traditional BCT during neurodevelopment.

METHODS

Longitudinal, observational, and descriptive study with 111 apparently healthy children divided into 4 groups: craniosacral-balance and coordination therapy placebo (CS-BCTp), craniosacral-balance and coordination therapy (CS-BCT), balance and coordination therapy placebo (BCTp), and balance and coordination therapy (BCT).

RESULTS

Significant changes have been observed with the CS-BCT from the fourth session. Balance and coordination therapy is less effective. There are differences in the Battelle Scale at the beginning and after the 7 therapy sessions in the CS-BCT group.

CONCLUSIONS

The study shows that CST together with balance and coordination exercises can be a more effective and faster treatment to improve these motor skills, correcting and improving alterations during child neurodevelopment.

Effects of osteopathic manipulative treatment associated with transcranial direct current stimulation in individuals with chronic low back pain: A double-blind, randomised placebo-controlled trial

OBJECTIVE

To evaluate the effectiveness of osteopathic manipulative treatment (OMT) associated with transcranial direct current stimulation (tDCS) in reducing pain, disability, and improving quality of life in participants with non-specific chronic low back pain.

DESIGN

A randomised double-blind clinical trial.

SETTING

Clinical outpatient unit.

SUBJECTS

72 participants with non-specific chronic low back pain were randomised into three groups: active tDCS + OMT (n = 24), sham tDCS + sham OMT (n = 24), and sham tDCS + OMT (n = 24).

INTERVENTIONS

Evaluations were performed before, after the intervention, and one month post-intervention. tDCS consisted of ten 20-minute sessions over two weeks (five sessions per week). OMT was administered once per week, with two sessions conducted before the first and sixth tDCS sessions.

MAIN MEASURES

Pain, disability, and quality of life were assessed at baseline, after two weeks, and at one month of follow-up.

RESULTS

The visual analogue scale showed a significant decrease in all groups (p < 0.001). However, tDCS + OMT and sham tDCS + OMT demonstrated a clinically significant reduction compared to the sham combination (effect size n² = 0.315). Roland-Morris scores decreased across all groups without specific group effects. EuroQoL 5-Dimension 3-Level improvement was observed only in the tDCS + OMT and sham tDCS + OMT groups (significant difference between T2 and T0, p = 0.002).

CONCLUSION

The combination of OMT and tDCS did not provide clinically significant improvement over OMT alone in participants with non-specific chronic low back pain.

Characteristics of the practice of New Zealand osteopaths who manage patients with chronic pain

BACKGROUND

Chronic pain management is challenging. Those with chronic pain present to health professionals, including osteopaths.

METHODS

Secondary analysis of a cross-sectional survey of the Osteopathy Research Connect - New Zealand (ORC-NZ), a practice-based research network (PBRN). Demographic, practice, and treatment characteristics of osteopaths who 'often' and 'not often' treat chronic pain patients were collected.

RESULTS

Two hundred and seventy-seven (277) NZ osteopaths responded and just over half (50.7% N = 138) reported 'often' treating chronic pain patients. This group, who have a similar male-to-female ratio, often use a diagnostic screening questionnaire (aOR 3.78), and often treat patients with non-musculoskeletal complaints (aOR 3.12) and tendinopathies (aOR 3.41).

CONCLUSIONS

This study highlights practice and clinical management characteristics of NZ osteopaths who manage chronic pain patients.

Is Osteopathic Manipulative Treatment Clinically Superior to Sham or Placebo for Patients with Neck or Low-Back Pain? A Systematic Review with Meta-Analysis

Objectives: The aim of this systematic review and meta-analysis was to compare whether osteopathic manipulative treatment (OMT) for somatic dysfunctions was more effective than sham or placebo interventions in improving pain intensity, disability, and quality of life for patients with neck pain (NP) or low-back pain (LBP). Methods: A systematic review and meta-analysis was carried out. Searches were conducted in PubMed, Physiotherapy Evidence Database, Cochrane Library, and Web of Science from inception to September 2024. Studies applying a pragmatic intervention based on the diagnosis of somatic dysfunctions in patients with NP or LBP were included. The methodological quality was assessed with the PEDro scale. The quantitative synthesis was performed using random-effect meta-analysis calculating the standardized mean difference (SMD) with RevMan 5.4. The certainty of evidence was evaluated using GRADEPro. Results: Nine studies were included in the qualitative synthesis, and most of them showed no superior effect of OMTs compared to sham or placebo in any clinical outcome. The quantitative synthesis reported no statistically significant differences for pain intensity (SMD = -0.15; -0.38, 0.08; seven studies; 1173 patients) or disability (SMD = -0.09; -0.25, 0.08; six studies; 1153 patients). The certainty of evidence was downgraded to moderate, low, or very low. Conclusions: The findings of this study reveal that OMT is not superior to sham or placebo for improving pain, disability, and quality of life in patients with NP or LBP.

Effectiveness of osteopathic craniosacral techniques: a meta-analysis

Background

Craniosacral osteopathic manipulative medicine-also known as craniosacral therapy (CST)-is a widely taught and used component of osteopathic medicine. This paper seeks to systematically review and conduct a meta-analysis of randomized controlled trials assessing the clinical effectiveness of CST compared to standard care, sham treatment, or no treatment in adults and children.

Methods

A search of Embase, PubMed, and Scopus was conducted on 10/29/2023 and updated on 5/8/2024. There was no restriction placed on the date of publication. A Google Scholar search was conducted to capture grey literature. Backward citation searching was also implemented. All randomized controlled trials employing CST for any clinical outcome were included. Studies not available in English as well as studies that did not report adequate data were excluded. Multiple reviewers were used to assess for inclusions, disagreements were settled by consensus. PRISMA guidelines were followed in the reporting of this meta-analysis. Cochrane's Risk of Bias 2 tool was used to assess for risk of bias. All data were extracted by multiple independent observers. Effect sizes were calculated using a Hedge's G value (standardized mean difference) and aggregated using random effects models. The GRADE system was used to assess quality of evidence.

Results

The primary study outcome was the effectiveness of CST for selected outcomes as applied to non-healthy adults or children and measured by standardized mean difference effect size. Twenty-four RCTs were included in the final meta-analysis with a total of 1,613 participants. When subgroup analyses were performed by primary outcome only, no significant effects were found. When secondary outcomes were included in subgroup analyses, results showed that only Neonate health, structure (g = 0.66, 95% CI [0.30; 1.02], Prediction Interval [-0.73; 2.05]) and Pain, chronic somatic (g = 0.34, 95% CI [0.18; 0.50], Prediction Interval [-0.41; 1.09]) show reliable, statistically significant effect. However, these should not be interpreted as positive results as wide prediction intervals, high bias, and statistical limitations temper the real-world implications of this finding.

Conclusions and relevance

CST demonstrated no significant effects in this meta-analysis, indicating a lack of usefulness in patient care for any of the studied indications.Pre-registration available at https://doi.org/10.17605/OSF.IO/54K6G.

A Critical Appraisal of Reporting in Randomized Controlled Trials Investigating Osteopathic Manipulative Treatment: A Meta-Research Study

Background/Objectives: In osteopathy, it becomes necessary to produce high-quality evidence to demonstrate its effectiveness. The aim of this meta-research study is to assess the reporting quality of RCTs published in the osteopathic field. Methods: The protocol was preliminarily registered on the "Open Science Framework (OSF)" website. For reporting, we considered the PRISMA 2020 checklist. We included all the RCTs, published between 2011 and 2023, investigating the effectiveness of Osteopathic Manipulative Treatment (OMT) in any possible condition. The search process was conducted on four major biomedical databases including PubMed, Central, Scopus and Embase. A data extraction form was implemented to collect all relevant information. The completeness of reporting was calculated as the percentage of adherence to the CONSORT checklist; the Cochrane ROB 2 tool was considered to assess the risk of bias (RoB) in the following five major domains: randomization (D1), interventions (D2), missing data (D3), outcome measurement (D4), selective reporting (D5). Results: A total of 131 studies were included and the overall adherence was 57%, with the worst section being "other information" (42%). Studies with a lower RoB showed higher adherence to the CONSORT. The "results" section presented the highest differences as follows: D1 (-36.7%), D2 (-27.2%), D3 (-21.5%) and D5 (-25.5%). Significant correlations were also found between the preliminary protocol registration, higher journal quartile, publication in hybrid journals and the completeness of reporting (β: 19.22, CI: 14.45-24.00, p < 0.001; β: 5.41; CI: 2.80-8.02, p ≤ 0.001; β: 5.64, CI: 1.06-10.23, p = 0.016, respectively). Conclusions: The adherence to the CONSORT checklist in osteopathic RCTs is lacking. An association was found between a lower completeness of reporting and a higher RoB, a good journal ranking, publication in hybrid journals and a prospective protocol registration. Journals and authors should adopt all the strategies to adhere to reporting guidelines to guarantee generalization of the results arising from RCTs.

Data-driven analysis of whole-brain intrinsic connectivity in patients with chronic low back pain undergoing osteopathic manipulative treatment

BACKGROUND

Chronic Low Back Pain (cLBP) poses a significant health challenge, leading to functional disability and reduced quality of life. Osteopathic Manipulative Treatment (OMT) is emerging as a therapeutic option for cLBP, but the brain mechanisms underlying its analgesic effect remain unclear.

MATERIALS AND METHODS

Thirty cLBP patients were randomly exposed to either four weekly sessions of OMT (N=16) or Sham treatment (N=14). Resting-state Magnetic Resonance Imaging (rs-MRI) scans and pain perception questionnaires were collected before and after treatment. A voxel-wise, rs-fMRI data-driven analysis was conducted to identify changes in the intrinsic functional connectivity across the whole brain that were associated with the OMT. Spearman's correlations were used to test for the association between changes in intrinsic connectivity and individual reports of pain perception.

RESULTS

Compared to the Sham group, participants who received OMT showed significant alterations in the functional connectivity of several regions belonging to the pain matrix. Specifically, OMT was associated with decreased connectivity of a parietal cluster that includes the somatosensory cortex and an increase of connectivity of the right anterior insula and ventral and dorsal anterolateral prefrontal areas. Crucially, the change in connectivity strength observed in the ventral anterolateral prefrontal cortex, a putative region of the affective-reappraisive layer of the pain matrix, correlates with the reduction in pain perception caused by the OMT.

CONCLUSIONS

This study offers insights into the brain mechanisms underlying the analgesic effect of OMT. Our findings support a link between OMT-driven functional cortical architecture alterations and improved clinical outcomes.

Cervical manipulation versus thoracic or cervicothoracic manipulations for the management of neck pain. A systematic review and meta-analysis

BACKGROUND

Cervical and thoracic thrust or non-thrust manipulations have shown to be effective in patients with neck pain, but there is a lack of studies comparing both interventions in patients with neck pain.

OBJECTIVE

To investigate the effects of cervical thrust or non-thrust manipulations compared to thoracic or cervicothoracic manipulations for improving pain, disability, and range of motion in patients with neck pain.

DESIGN

Systematic review and meta-analysis.

METHOD

Searches were performed in PubMed, PEDro, Cochrane Library, CINHAL, and Web of Science databases from inception to May 22, 2023. Randomized clinical trials comparing cervical thrust or non-thrust manipulations to thoracic or cervicothoracic manipulations were included. Methodological quality was assessed with PEDro scale, and the certainty of evidence was evaluated using GRADE guidelines.

RESULTS

Six studies were included. Meta-analyses revealed no differences between cervical thrust or non-thrust manipulations and thoracic or cervicothoracic manipulations in pain intensity, disability, or cervical range of motion in any plane. The certainty of evidence was downgraded to very low for pain intensity, to moderate or very low for disability and to low or very low for cervical range of motion.

CONCLUSION

There is moderate to very low certainty evidence that there is no difference in effectiveness between cervical thrust or non-thrust manipulations and thoracic or cervicothoracic manipulations for improving pain, disability, and range of motion in patients with neck pain.

Reported biological effects following Osteopathic Manipulative Treatment: A comprehensive mapping review

BACKGROUND AND PURPOSE

Osteopathic Manipulative Treatment (OMT) is a therapeutic whole-body approach mainly focused on correcting somatic dysfunctions. The aim of this scoping review is to systematically map the literature regarding the documented biological effects observed following OMT.

METHODS

The 2020 JBIRM version and the PRISMA-ScR were followed for the conceptualization and reporting of this review. The protocol was registered on the "Open Science Framework Registry" (https://doi.org/10.17605/OSF.IO/MFAUP). We searched for original articles published on Medline, Embase, and Scopus, from inception to the present.

RESULTS

Overall, 10,419 records were identified. After duplicate removal, screening for title and abstract, and specific exclusions with reasons, a total of 146 studies were included. Wide differences were detected among studies in their geographical localization, study design, temporal distribution, participants' condition, OMT protocols, and documented biological effects. Such variety in frequency distribution was properly described through descriptive statistics.

CONCLUSIONS

Biological modifications that appear to be induced by OMT have been detected in several body systems, but mostly in neurophysiological correlates and musculoskeletal changes. Results suggest a growing interest over the years on this topic, especially in the last two decades. More efforts in research are recommended to highlight whether such changes specifically depend on OMT, and to demonstrate its specific contribution to clinical practice.

The effects of osteopathic manipulative treatment on pain and disability in patients with chronic low back pain: a single-blinded randomized controlled trial

CONTEXT

The evidence for the efficacy of osteopathic manipulative treatment (OMT) in the management of low back pain (LBP) is considered weak by systematic reviews, because it is generally based on low-quality studies. Consequently, there is a need for more randomized controlled trials (RCTs) with a low risk of bias.

OBJECTIVES

The objective of this study is to evaluate the efficacy of an OMT intervention for reducing pain and disability in patients with chronic LBP.

METHODS

A single-blinded, crossover, RCT was conducted at a university-based health system. Participants were adults, 21-65 years old, with nonspecific LBP. Eligible participants (n=80) were randomized to two trial arms: an immediate OMT intervention group and a delayed OMT (waiting period) group. The intervention consisted of three to four OMT sessions over 4-6 weeks, after which the participants switched (crossed-over) groups. The primary clinical outcomes were average pain, current pain, Patient-Reported Outcomes Measurement Information System (PROMIS) 29 v1.0 pain interference and physical function, and modified Oswestry Disability Index (ODI). Secondary outcomes included the remaining PROMIS health domains and the Fear Avoidance Beliefs Questionnaire (FABQ). These measures were taken at baseline (T0), after one OMT session (T1), at the crossover point (T2), and at the end of the trial (T3). Due to the carryover effects of OMT intervention, only the outcomes obtained prior to T2 were evaluated utilizing mixed-effects models and after adjusting for baseline values.

RESULTS

Totals of 35 and 36 participants with chronic LBP were available for the analysis at T1 in the immediate OMT and waiting period groups, respectively, whereas 31 and 33 participants were available for the analysis at T2 in the immediate OMT and waiting period groups, respectively. After one session of OMT (T1), the analysis showed a significant reduction in the secondary outcomes of sleep disturbance and anxiety compared to the waiting period group. Following the entire intervention period (T2), the immediate OMT group demonstrated a significantly better average pain outcome. The effect size was a 0.8 standard deviation (SD), rendering the reduction in pain clinically significant. Further, the improvement in anxiety remained statistically significant. No study-related serious adverse events (AEs) were reported.

CONCLUSIONS

OMT intervention is safe and effective in reducing pain along with improving sleep and anxiety profiles in patients with chronic LBP.

Diagnosis and Treatment of Low Back Pain: Synopsis of the 2021 US Department of Veterans Affairs and US Department of Defense Clinical Practice Guideline

ABSTRACT

Low back pain is a significant issue in the US Department of Veterans Affairs and Department of Defense populations as well as the general US population at large. This type of pain can be distressing to those who experience its effects, leading patients to seek relief of their symptoms. In 2022, leadership within the US Department of Veterans Affairs and US Department of Defense approved a joint clinical practice guideline for the management of low back pain. The guideline provides evidence-based recommendations for assessing and managing low back pain. Development of the guideline included a systematic evidence review, which was guided by 12 key questions. A multidisciplinary team, which included clinical stakeholders, reviewed the evidence that was retrieved and developed 39 recommendations using the Grading of Recommendations Assessment, Development, and Evaluation system. The scope of the clinical practice guideline is broad; however, the authors have focused on key recommendations that are important for clinicians in the evaluation and nonoperative treatment of low back pain, including pharmacologic therapies and both noninvasive and invasive nonpharmacologic treatments.

Does Osteopathic Heart-Focused Palpation Modify Heart Rate Variability in Stressed Participants with Musculoskeletal Pain? A Randomised Controlled Pilot Study

Heart rate variability (HRV) describes fluctuations in time intervals between heartbeats and reflects autonomic activity. HRV is reduced in stressed patients with musculoskeletal pain and improved after osteopathic manipulative treatment and mind-body interventions. Heart-focused palpation (HFP) combines manual and mind-body approaches to facilitate relaxation. This randomised controlled pilot study investigated the feasibility and sample size for a future randomised controlled trial and the effect of a single treatment with HFP or sham HFP (SHAM) on short-term HRV. A total of Thirty-three adults (47.7 ± 13.5 years old) with stress and musculoskeletal pain completed the trial with acceptable rates of recruitment (8.25 subjects per site/month), retention (100%), adherence (100%), and adverse events (0%). HFP (n = 18), but not SHAM (n = 15), significantly increased the root mean square of successive RR interval differences (p = 0.036), standard deviation of the NN intervals (p = 0.009), and ratio of the low-frequency to high-frequency power band (p = 0.026). HFP and SHAM significantly decreased the heart rate (p < 0.001, p = 0.009) but not the stress index and ratio of the Poincaré plot standard deviation along and perpendicular to the line of identity (p > 0.05). A power analysis calculated 72 participants. Taken together, the study was feasible and HFP improved HRV in stressed subjects with musculoskeletal pain, suggesting a parasympathetic effect.

Effectiveness of aquatic training based on aerobic and strengthening exercises in patients with fibromyalgia: systematic review with meta-analysis

BACKGROUND AND PURPOSE

fibromyalgia is a chronic condition causing widespread pain, fatigue, limited physical function, and reduced quality of life. Aquatic training is recommended as a first-line non-pharmacological treatment. This study aims to evaluate the effectiveness of aquatic training based on aerobic and strengthening exercises in improving symptoms in women with fibromyalgia.

MATERIAL AND METHODS

a systematic review with meta-analysis was conducted by searching the PubMed, Scopus, Cochrane Library and Web of Science databases. Randomized clinical trials that compared aquatic therapy with either a control group or a land-based exercise group were included. Study quality was assessed using the PEDro scale, the risk of bias was evaluated using the Cochrane Risk of Bias Tool, and the certainty of the evidence was assessed the GRADE guidelines.

RESULTS

six randomized clinical trials comprising 9 publications showed that aquatic therapy had statistically significant benefits compared to no intervention, including pain, fatigue, fibromyalgia impact, depression, physical function, and mental health in the short term. In the medium term, improvements were observed in fibromyalgia impact, physical function, and mental health. However, aquatic therapy was not found to be superior to land-based exercise.

CONCLUSION

low to very low certainty of evidence suggested that aquatic training may reduce pain, fibromyalgia impact, fatigue and depression and improve physical function and mental health in patients with fibromyalgia. Further studies should investigate the medium and long-term effects of aquatic training using larger sample sizes.

Short-term effects of cupping and scraping therapy for chronic nonspecific low-back pain: A prospective, multicenter randomized trial

BACKGROUND

As one of the most common musculoskeletal ailments, chronic nonspecific low-back pain (CNLBP) causes persistent disability and substantial medical expenses. Epidemiological evidence shows that the incidence rate of CNLBP in young and middle-aged people who are demanded rapidly recovery and social contribution is rising. Recent guidelines indicate a reduced role for medicines in the management of CNLBP.

OBJECTIVE

The present study investigates the short-term effects of cupping and scraping therapy using a medicated balm, compared to nonsteroidal anti-inflammatory drug (NSAID) with a capsaicin plaster, in the treatment of CNLBP.

DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS

We designed a prospective multicenter randomized clinical trial enrolling patients from January 1, 2022 to December 31, 2022. A total of 156 patients with CNLBP were randomized into two parallel groups. Diclofenac sodium-sustained release tablets were administered orally to participants in the control group for one week while a capsaicin plaster was applied externally. Patients in the test group were treated with cupping and scraping using a medical device and medicated balm.

MAIN OUTCOME MEASURES

Primary outcome was pain recorded using the visual analogue scale (VAS). Two secondary outcomes were recorded using the Japanese Orthopedic Association low-back pain scale (JOA) and the traditional Chinese medicine (TCM) syndrome integral scale (TCMS) as assessment tools.

RESULTS

Between baseline and postintervention, all changes in outcome metric scales were statistically significant (P < 0.001). Compared to the control group, patients in the test group had a significantly greater treatment effect in all outcome variables, as indicated by lower VAS and TCMS scores and higher JOA scores, after the one-week intervention period (P < 0.001). Further, according to the findings of multivariate linear regression analysis, the participants' pain (VAS score) was related to their marital status, age, smoking habits and body mass index. No adverse reactions were reported for any participants in this trial.

CONCLUSION

The effectiveness of TCM combined with the new physiotherapy tool is superior to that of NSAID combined with topical plasters, regarding to pain intensity, TCM symptoms and quality of life. The TCM plus physiotherapy also showed more stable and long-lasting therapeutic effects.

Fast improvements in functional status after osteopathic manipulative treatment based on myofascial release in patients with moderate or severe fibromyalgia: a retrospective study

OBJECTIVES

Fibromyalgia (FM) is a chronic pain syndrome characterized by a large variety of symptoms. Evidence suggests that an alteration of central nervous system processing of pain could be involved. The purpose of this study is to analyze clinical records of patients affected by FM who underwent osteopathic manipulative treatment (OMT), predominantly based on a myofascial release approach (MFR).

METHODS

This retrospective study considered records of 21 FM patients with moderate or severe functional impact, who consented to OMT in addition to their usual care. The assessment considered the following measures: FIQ (functional status), SF36 (quality of life), VAS (pain), TSK (kinesiophobia) and PSQI (quality of sleeping). Patients were preliminarily assessed over a 1 month run-in phase, then after 1, 2 and 4 months; a 1 month follow-up was also considered.

RESULTS

After one month, 71% of patients reported a decrease in functional impact and scores remained stable until follow-up (from 69.8 to 52.37, p≤0.001). Overall, after four months, patients improved their quality of life, with a score ranging from 33.47 to 42.6 (p≤0.05). We also observed a reduction of pain (p≤0.05).

CONCLUSIONS

A series of OMT sessions based on MFR could play a therapeutic role in improving functional status, pain and quality of life over a period of 4 months.

Valid and Invalid Indications for Osteopathic Interventions: A Systematic Review of Evidence-Based Practices and French Healthcare Society Recommendations

The main aim of this study was to determine the level of evidence in the literature for the main indications of osteopathy as recommended by the French osteopathy societies. This systematic review followed the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and evaluated articles published between January 2012 and January 2022 with one modification: when level one evidence studies were available, level two to five studies were excluded. Sources included PubMed, the Cochrane library, the French National Health Authority (HAS) and its affiliates. Inclusion criteria were level one published studies on the indications for osteopathic treatment in French and English, and level two to three studies when no level one studies were available. The level of evidence assessment was based on the Oxford Centre for Evidence-Based Medicine (OCEBM) Levels of Evidence classification. The primary outcome was the level of evidence in the literature supporting osteopathic practices. The secondary outcome was to assess French professional osteopathy recommendations and French HAS guidelines in relation to the scientific literature. A total of 51 articles and nine recommendations from the HAS and its affiliates met the inclusion criteria for the systematic review. Analysis of the studies revealed 41 osteopathic indications from French osteopathy societies for musculoskeletal, neurosensory, psychological, pediatric, gynecological, digestive, and pulmonary disorders. High-level scientific evidence supported the use of osteopathy for low back pain, sciatica, cervical radiculopathy, and ankle sprain. There was moderate evidence for tension headache, temporomandibular joint disorder, endometriosis, and low back and pelvic pain in pregnant women. HAS recommended five indications, while nine indications were supported in the scientific literature. Osteopathy has been shown to have evidence-based benefits for a range of conditions, in particular for musculoskeletal and neurosensory disorders.

Bibliometric Analysis of Research Trends on Manual Therapy for Low Back Pain Over Past 2 Decades

Purpose

Low back pain (LBP) is a prevalent musculoskeletal disorder, and manual therapy (MT) is frequently employed as a non-pharmacological treatment for LBP. This study aims to explore the research hotspots and trends in MT for LBP. MT has gained widespread acceptance in clinical practice due to its proven safety and effectiveness. The study aims to analyze the developments in the field of MT for LBP over the past 23 years, including leading countries, institutions, authoritative authors, journals, keywords, and references. It endeavors to provide a comprehensive summary of the existing research foundation and to analyze the current cutting-edge research trends.

Methods

Relevant articles between 2000 and 2023 were retrieved from the Web of Science Core Collection (WOSCC) database. We used the software VOSviewer and CiteSpace to perform the analysis and summarize current research hotspots and emerging trends.

Results

Through screening, we included 1643 papers from 2000 to 2023. In general, the number of articles published each year showed an upward trend. The United States had the highest number of publications and citations. Canadian Memorial Chiropractic College was the most published research institution. The University of Pittsburgh in the United States had the most collaboration with other research institutions. Long, Cynthia R. was the active author. Journal of Manipulative and Physiological Therapeutics was the most prolific journal with 234 publications.

Conclusion

This study provides an overview of the current status and trends of clinical studies on MT for LBP in the past 23 years using the visualization software, which may help researchers identify potential collaborators and collaborating institutions, hot topics, and new perspectives in research frontiers, while providing new clinical practice ideas for the treatment of LBP.

The effectiveness of non-surgical interventions in athletes with groin pain: a systematic review and meta-analysis

BACKGROUND

Groin pain is a common pathology among athletes, presenting pain and a reduced range of motion (ROM) as clinical characteristics. Passive physical therapy (PPT) and exercise therapy (ET) interventions are chosen firstly before surgery. The aim of this systematic review and meta-analysis was: (i) to qualitative review the effects of each non-surgical intervention; (ii) to quantitative compare the effects of PPTs plus ET intervention to ET in isolation in pain intensity, and hip ROM in athletes with groin pain.

METHODS

A systematic review and meta-analysis was conducted. Pubmed, PEDro, Web of science, Scopus and Cochrane library were searched. Randomized controlled trials comparing PPT plus ET to ET interventions were included. The methodological quality and risk of bias of the included studies, were assessed with the PEDro scale and the Cochrane risk-of-bias tool. To assess the certainty of evidence the GRADEpro GDT was used. Meta-analyses were conducted using RevMan 5.4 using mean difference analysis to assess the variables pain intensity and hip ROM.

RESULTS

A total of 175 studies was identified from the consulted databases. Five studies were included for systematic- review, from which three studies were meta-analyzed. The methodological quality of the included studies ranged from poor to high. ET compared to PPT plus ET provided statistically significant improvements in pain intensity in the short-term (MD = 2.45; 95% CI 1.11, 3.79; I² :65%). No statistically significant differences between interventions were obtained for hip ROM in the short-term.

CONCLUSIONS

The qualitative review showed that PPTs plus ET and ET seem to have positive effects on pain intensity and hip ROM. The quantitative analysis found very low certainty of evidence proposing a positive effect in pain intensity for ET interventions based on hip muscles stretching, compared to PPT combined with ET, in the short-term.

Systematic review and meta-analysis showed that complementary and alternative medicines were not effective for infantile colic

AIM

Osteopathy and chiropractic techniques are used for babies for different reasons, but it is unclear how effective they are. The aim of this study was to evaluate their effectiveness in reducing crying time and increasing sleeping time in babies with infantile colic.

METHODS

A systematic review and meta-analysis was conducted on infantile colic studies that used complementary and alternative medicine techniques as interventions. The outcome measures were hours spent crying and/or sleeping. We used the PubMed, Physiotherapy Evidence Database, Cochrane Library, Embase, Web of Science, Scopus, Osteopathic Medicine Digital Database and Google Scholar databases from inception to 11 November 2022.

RESULTS

The methodological quality of the randomised control trials ranged from fair to high. We focused on five studies with 422 babies. Complementary treatments failed to decrease the crying time (mean difference -1.08, 95% CI: -2.17 to 0.01, I2  = 92%) and to increase sleeping time (mean difference 1.11, 95% CI: -0.20 to 2.41; I2 : 91%), compared with no intervention. The quality of the evidence was rated as very low for both outcome measures.

CONCLUSION

Osteopathy and chiropractic treatment failed to reduce the crying time and increase sleeping time in babies with infantile colic, compared with no additional intervention.

The effectiveness of hip interventions in patients with low-back pain: A systematic review and meta-analysis

BACKGROUND

Low-back pain (LBP) may be directly or indirectly related to impairments from the hip joint.

OBJECTIVE

To evaluate the effectiveness of hip interventions on pain and disability in patients with LBP in the short-, medium-, and long-term.

METHODS

PubMed, Cochrane Library, PEDro, Web of Science, and SCOPUS databases were searched in November 2022. Randomized controlled trials involving hip-targeted interventions compared to specific low back interventions in patients with LBP were selected. The outcomes were pain intensity and disability. The quality of the studies was assessed with the risk of bias tool. GRADE was used to rate the certainty of evidence. Meta-analyses were conducted using random effects models.

RESULTS

A total of 2581 studies were screened. Eight were included in the meta-analysis involving 508 patients with LBP. The results provided very low certainty that both hip strengthening and hip stretching improved pain (MD = -0.66; 95% CI -0.86, -0.48; I2:0%) (MD = -0.55; 95% CI -1.02, -0.08) and disability (SMD = -0.81; 95% CI -1.53, -0.10; I2: 80%) (SMD = -1.03; 95% CI -1.82, -0.25) in the short-term, respectively. No benefits were found in the medium- or long-term. The risk of bias, heterogeneity, and imprecision of the results downgraded the level of evidence.

CONCLUSIONS

Very low certainty evidence suggest a positive effect of hip strengthening in isolation or combined with specific low back exercise and hip stretching combined with specific low back exercise for decreasing pain intensity and disability in the short-term, in patients with LBP.

Comparison of Feng spinal mobilization with Maitland mobilization in management of chronic nonspecific low back pain: A cohort study

Feng spinal mobilization (FSM) is one of the most widely practiced techniques in traditional Chinese osteopathy, especially in China. However, whether this FSM technique is more effective than the Maitland posteroanterior mobilization (MM), which is widely used all over the world, is still unknown. The purpose of this study was to retrospectively analyze and compare the efficacy of these 2 treatments in patients with chronic nonspecific low back pain (CNLBP) as to provide a basis for the clinical treatment of chronic low back pain. A total of 83 patients, including 43 patients in the FSM group and 40 in the MM group, were enrolled in this cohort study. FSM or MM was performed on patients 3 times during a period of 2 weeks. Changes in the subjective and objective measurements were measured before and after the third treatment. The subjective symptoms recorded included the visual analogue scale (VAS), Oswestry disability index, and Patient Health Questionnaire-9. The objective symptoms, including the lumbar range of motion (ROM), and straight leg raise (SLR) height were also checked for any changes. The VAS scores were reassessed at the 1-year follow-up visit. The results showed that 2 weeks of FSM treatment significantly improved CNLBP patients modified Schober test (P < .05), extension ROM (P < .01), and SLR height (P < .05) while MM treatment did not. Both treatments significantly decreased the values of VAS, Oswestry disability index, and Patient Health Questionnaire-9 (P < .01). Compared to the MM treatment, the FSM treatment showed a much more significant improvement in VAS score (P < .01), range of motion of extension (P < .01), and SLR of both sides (P < .05). At the 1-year follow-up, VAS scores in both groups decreased significantly compared to pretreatments; however, there was no significant difference between the 2 groups. Our data suggested that the FSM treatment can provide better efficacy than MM in CNLBP patients, improving the VAS scores, lumbar extension ROM, and SLR height in a shorter time.

Assessment and management of pain/nociception in patients with disorders of consciousness or locked-in syndrome: A narrative review

The assessment and management of pain and nociception is very challenging in patients unable to communicate functionally such as patients with disorders of consciousness (DoC) or in locked-in syndrome (LIS). In a clinical setting, the detection of signs of pain and nociception by the medical staff is therefore essential for the wellbeing and management of these patients. However, there is still a lot unknown and a lack of clear guidelines regarding the assessment, management and treatment of pain and nociception in these populations. The purpose of this narrative review is to examine the current knowledge regarding this issue by covering different topics such as: the neurophysiology of pain and nociception (in healthy subjects and patients), the source and impact of nociception and pain in DoC and LIS and, finally, the assessment and treatment of pain and nociception in these populations. In this review we will also give possible research directions that could help to improve the management of this specific population of severely brain damaged patients.

Effects of osteopathic manipulative treatment associated with pain education and clinical hypnosis in individuals with chronic low back pain: study protocol for a randomized sham-controlled clinical trial

BACKGROUND

Patients with chronic low back pain (CLBP) suffer with functional, social, and psychological aspects. There is a growing number of studies with multimodal approaches in the management of these patients, combining physical and behavioral therapies such as osteopathic manipulative treatment, associating pain education and clinical hypnosis. The aim of the present study will be to evaluate the effects of osteopathic manipulative treatment (OMT) associated with pain neuroscience education (PNE) and clinical hypnosis (CH) on pain and disability in participants with CLBP compared to PNE, CH, and sham therapy.

METHODS

A randomized controlled clinical trial will be conducted in participants aged 20-60 years with CLBP who will be divided into two groups. Group 1 will receive PNE and CH associated with OMT, and G2 will receive PNE, CH, and sham therapy. In both groups, 4 interventions of a maximum of 50 min and with an interval of 7 days will be performed. As primary outcomes, pain (numerical pain scale), pressure pain threshold (pressure algometer), and disability (Oswestry Disability Questionnaire) will be evaluated and, as a secondary outcome, global impression of improvement (Percent of Improvement Scale), central sensitization (Central Sensitization Questionnaire), biopsychosocial aspects (Start Beck Toll Questionnaire), and behavior of the autonomic nervous system (heart rate variability) will be assessed. Participants will be evaluated in the pre-intervention moments, immediately after the end of the protocol and 4 weeks after the procedures. Randomization will be created through a simple randomized sequence and the evaluator will be blinded to the allocation of intervention groups.

DISCUSSION

The guidelines have been encouraging multimodal, biopsychosocial approaches for patients with CLBP; in this sense, the results of this study can help clinicians and researchers in the implementation of a model of treatment strategy for these patients. In addition, patients may benefit from approaches with minimal risk of deleterious effects and low cost. In addition, it will enable the addition of relevant elements to the literature, with approaches that interact and do not segment the body and brain of patients with CLBP, allowing new studies in this scenario.

Sport and non-specific low back pain in athletes: a scoping review

BACKGROUND

The contribution of sport in non-specific low back pain (NS-LBP) remains unknown, due to a large heterogeneity in the methods applied in research. The aims of this scoping review (ScR) were to systematically map and summarize findings concerning studies reporting data on NS-LBP among athletes.

METHODS

This ScR was developed referring to the 2020 version of the "Joanna Briggs Institute Methodological Guidance" and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews. Five medical databases (Pubmed, Cochrane, Central, Embase, Pedro and Scopus) were searched up to November 2021. No limitations in terms of study design and language were applied. Results were presented numerically and thematically.

RESULTS

A total of 4061 records were identified through the initial search; 114 articles met the inclusion criteria. Publications have increased over the years, since 1990. Most of the studies were conducted in the USA (17.5%), even if most research was conducted in Europe (53.5%). Analytic observational (42%) and cross-sectional studies (37%) were the most used designs, followed by case reports (12%) and systematic reviews (9%). Boating (7%), football, soccer, volleyball, running and gymnastics (4.4% each) were the most investigated, although the majority of the studies considered sports in general (36.8%). The overall sample size median was 181, mean age 22 ± 10.2; 68% of athletes were professional and 32% amateur. Most of the studies (38%) did not detail the frequency of training. Sport was reported as a risk factor for developing NS-LBP in 67.5% of cases, especially in those studies which assessed activities implying high or repeated loading on the spine.

CONCLUSIONS

This is the first ScR to provide a comprehensive overview on this topic. The increased number of publications on the association between sport practice and NS-LBP demonstrates a growing interest over the years on this topic. Some sport activities seem to be more involved than others in LBP development; however, research methods are extremely varied, thus more standardized observational research may focus on specific disciplines to properly contribute to research and clinical practice.

Effect of osteopathic techniques on human resting muscle tone in healthy subjects using myotonometry: a factorial randomized trial

Musculoskeletal disorders (MSDs) are highly prevalent, burdensome, and putatively associated with an altered human resting muscle tone (HRMT). Osteopathic manipulative treatment (OMT) is commonly and effectively applied to treat MSDs and reputedly influences the HRMT. Arguably, OMT may modulate alterations in HRMT underlying MSDs. However, there is sparse evidence even for the effect of OMT on HRMT in healthy subjects. A 3 × 3 factorial randomised trial was performed to investigate the effect of myofascial release (MRT), muscle energy (MET), and soft tissue techniques (STT) on the HRMT of the corrugator supercilii (CS), superficial masseter (SM), and upper trapezius muscles (UT) in healthy subjects in Hamburg, Germany. Participants were randomised into three groups (1:1:1 allocation ratio) receiving treatment, according to different muscle-technique pairings, over the course of three sessions with one-week washout periods. We assessed the effect of osteopathic techniques on muscle tone (F), biomechanical (S, D), and viscoelastic properties (R, C) from baseline to follow-up (primary objective) and tested if specific muscle-technique pairs modulate the effect pre- to post-intervention (secondary objective) using the MyotonPRO (at rest). Ancillary, we investigate if these putative effects may differ between the sexes. Data were analysed using descriptive (mean, standard deviation, and quantiles) and inductive statistics (Bayesian ANOVA). 59 healthy participants were randomised into three groups and two subjects dropped out from one group (n = 20; n = 20; n = 19-2). The CS produced frequent measurement errors and was excluded from analysis. OMT significantly changed F (-0.163 [0.060]; p = 0.008), S (-3.060 [1.563]; p = 0.048), R (0.594 [0.141]; p < 0.001), and C (0.038 [0.017]; p = 0.028) but not D (0.011 [0.017]; p = 0.527). The effect was not significantly modulated by muscle-technique pairings (p > 0.05). Subgroup analysis revealed a significant sex-specific difference for F from baseline to follow-up. No adverse events were reported. OMT modified the HRMT in healthy subjects which may inform future research on MSDs. In detail, MRT, MET, and STT reduced the muscle tone (F), decreased biomechanical (S not D), and increased viscoelastic properties (R and C) of the SM and UT (CS was not measurable). However, the effect on HRMT was not modulated by muscle-technique interaction and showed sex-specific differences only for F.Trial registration German Clinical Trial Register (DRKS00020393).

Evidence (-based medicine) in manual medicine/manual therapy—a summary review

Objective

The aim of this summary review is to analyse the current state of evidence in manual medicine or manual therapy.

Methods

The literature search focussed on systematic reviews listed in PubMed referring to manual medicine treatment until the beginning of 2022, limited to publications in English or German. The search concentrates on (1) manipulation, (2) mobilization, (3) functional/musculoskeletal and (4) fascia. The CASP Checklist for Systematic Reviews was used to present the included reviews in a clear way.

Results

A total of 67 publications were included and herewith five categories: low back pain, neck pain, extremities, temporomandibular disorders and additional effects. The results were grouped in accordance with study questions.

Conclusion

Based on the current systematic reviews, a general evidence-based medicine level III is available, with individual studies reaching level II or Ib. This allows manual medicine treatment or manual therapy to be used in a valid manner.

Beliefs and Use of Palpatory Findings in Osteopathic Clinical Practice: A Qualitative Descriptive Study among Italian Osteopaths

The Italian government has started the regulatory process of osteopathy to include it among the healthcare professions mentioning terms, such as “perceptual palpation” and “somatic dysfunction” within the professional profile. ‘Palpatory findings’ are one of the multidimensional aspects that can inform osteopathic clinical reasoning. The non-regulated educational system has led to heterogenic professionals working in Italy, thus, the aim of this study was to investigate how Italian experts use palpatory findings in their clinical practice. A total of 12 experts were selected to participate in four virtual focus groups. A qualitative inductive approach with a constructivist paradigm was chosen to describe the results. The themes that emerged were: osteopathic identity; evaluation; osteopathic diagnosis; and sharing with different recipients. Participants agreed on the peculiarity and distinctiveness of osteopathic palpation, but there was some disagreement on the clinical significance of the findings, highlighting a complex multidimensional approach to diagnosis and treatment. The results seem to reflect the history of the profession in Italy, which has evolved quickly, leading professionals to seek new paradigms blending tradition and scientific evidence. The authors suggest further investigation to verify the state of art among osteopaths not involved in research or a broader consensus of the results.

The Role of Osteopathic Care in Gynaecology and Obstetrics: An Updated Systematic Review

Background: Many efforts are made to find safer and more feasible therapeutic strategies to improve gynaecological care. Non-pharmacological treatments, such as osteopathic interventions, could be used as complementary strategies to better manage different gynaecological conditions. This review aims to report the effectiveness of osteopathic treatment in the gynaecology and obstetrics field, updating the previous review published in 2016. The secondary aim was to elucidate the role of somatic dysfunction (SD) in osteopathic assessment and treatment procedures, as well as their health and economic implications. Methods: An electronic search was conducted in the following databases: Embase, MEDLINE (PubMed), and Science direct. All types of clinical studies published between May 2014 and December 2021 have been included: randomised controlled trial (RCT), controlled before/after, interrupted time series quasi RCT, case controls, case reports, case series, observational, clinical studies involving any type of osteopathic treatment, (standardised, semi-standardised or patients’ need-based treatment) performed alone or in combination with other treatments, were included). Results: A total of 76,750 were identified through database searching and other sources. After the removal of duplicates, 47,655 papers were screened based on title and abstract. A total of 131 full-text articles were consequently assessed for eligibility. Twenty-one new articles were included in the synthesis. A total of 2632 participants with a mean age of 28.9 ± 10.5 years were included in the review. Conclusions: Results showed an effectiveness of osteopathic care in gynaecology and obstetrics, but the studies were too heterogeneous to perform quantitative analysis and make clinical recommendations. Nevertheless, osteopathic care could be considered a safe complementary approach to traditional gynaecological care.

Effectiveness of osteopathic interventions in patients with non-specific neck pain: A systematic review and meta-analysis

OBJECTIVE

The aim of this systematic review and meta-analysis is to evaluate whether osteopathic manipulative interventions can reduce pain levels and enhance the functional status in patients with non-specific neck pain (NS-NP).

METHODS

A systematic review and meta-analysis was conducted following the 2020 PRISMA statement. Randomized controlled trials (RCTs) were searched in five databases, assessed through a standardized form, and evaluated using the "13 items Cochrane risk of bias (RoB) tool". Effect sizes (ES) were calculated post-treatment, and the quality of evidence was assessed through GRADE criteria.

RESULTS

Five articles were included in the review, and none of these was completely judged at low RoB. Four of these were included in the meta-analysis. Osteopathic interventions compared to no intervention/sham treatment showed statistically significant results for pain levels (ES = -1.57 [-2.50, -0.65]; P = 0.0008) and functional status (ES = -1.71 [-3.12, -0.31]; P = 0.02). The quality of evidence was "very low" for all the assessed outcomes. Other results were presented in a qualitative synthesis.

CONCLUSIONS

Osteopathic interventions could be effective for pain levels and functional status improvements in adults with NS-NP. However, these findings are affected by a very low quality of evidence. Therefore, further high-quality RCTs are necessary to improve the quality of evidence and generalize the results.

Chronic Pain and Emotional Stroop: A Systematic Review

Chronic pain is an unpleasant sensory and emotional experience that persists for more than 3 months and is often accompanied by symptoms such as depression, fatigue, sleep disturbances, and cognitive impairment. Emotional dysregulation may also be involved in its etiology. Emotions are known to modulate the experience of pain by influencing cognition and behavior (emotional awareness, emotional expression and experience, and verbalizations). A useful task to explore emotional processing and emotional dysregulation is the emotional Stroop task. Despite the large number of studies using this task, their objectives are diverse; it is necessary to integrate them. The main objective of the present systematic review was to determine the extent of the abnormalities in behavioral performance (including attentional biases) and/or brain alterations in patients with chronic pain during the emotional Stroop task. This systematic review was conducted in accordance with the Cochrane Collaboration guidelines and Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. The protocol was previously registered in the Prospective Register of Systematic Reviews (PROSPERO) international database. The selected articles were extracted from the PubMed, Scopus, and Web of Science databases. Fifteen studies were identified as eligible for systematic review. The studies reported alterations in brain regions related to pain and emotional regulation, as well as attentional bias and higher response time latencies (related to the words’ emotional load) in patients with chronic pain. The results confirm the validity of the emotional Stroop task to measure emotions and selective attention. As attentional bias towards negative information is often seen in chronic pain patients, and given the relation between selective attention and greater activation of the brain areas associated with pain and emotional processing, this type of task plays a crucial role in research on emotional and attentional processes among chronic pain patients. Further, attentional bias towards negative information has been associated with higher levels of pain. Taken together, the results suggest the need for cognitive training and an emotional approach to chronic pain therapies, especially targeting attentional biases and negative mood.

Efficacy and safety of osteopathic manipulative treatment: an overview of systematic reviews

OBJECTIVE

To summarise the available clinical evidence on the efficacy and safety of osteopathic manipulative treatment (OMT) for different conditions.

DESIGN

Overview of systematic reviews (SRs) and meta-analyses (MAs). PROSPERO CRD42020170983.

DATA SOURCES

An electronic search was performed using seven databases: PubMed, EMBASE, CINAHL, Scopus, JBI, Prospero and Cochrane Library, from their inception until November 2021.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

SRs and MAs of randomised controlled trials evaluating the efficacy and safety of OMT for any condition were included.

DATA EXTRACTION AND SYNTHESIS

The data were independently extracted by two authors. The AMSTAR-2 tool was used to assess the methodological quality of the SRs and MAs. The overview was conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

RESULTS

The literature search revealed nine SRs or MAs conducted between 2013 and 2020 with 55 primary trials involving 3740 participants. The SRs reported a wide range of conditions including acute and chronic non-specific low back pain (NSLBP, four SRs), chronic non-specific neck pain (CNSNP, one SR), chronic non-cancer pain (CNCP, one SR), paediatric (one SR), neurological (primary headache, one SR) and irritable bowel syndrome (IBS, one SR). Although with a different effect size and quality of evidence, MAs reported that OMT is more effective than comparators in reducing pain and improving functional status in acute/chronic NSLBP, CNSNP and CNCP. Due to small sample size, presence of conflicting results and high heterogeneity, questionable evidence existed on OMT efficacy for paediatric conditions, primary headache and IBS.No adverse events were reported in most SRs. According to AMSTAR-2, the methodological quality of the included SRs was rated low or critically low.

CONCLUSION

Based on the currently available SRs and MAs, promising evidence suggests the possible effectiveness of OMT for musculoskeletal disorders. Limited and inconclusive evidence occurs for paediatric conditions, primary headache and IBS. Further well-conducted SRs and MAs are needed to confirm and extend the efficacy and safety of OMT.

Effectiveness of Myofascial Manual Therapies in Chronic Pelvic Pain Syndrome: A Systematic Review and Meta-Analysis

INTRODUCTION AND HYPOTHESIS

Chronic pelvic pain syndrome (CPPS) is defined as the occurrence of chronic pelvic pain (CPP) in the absence of a specific cause. People typically refer to pain associated with urological, gynaecological, and sexual dysfunction, affecting the quality of life. Therefore, we assessed the effectiveness of myofascial manual therapies (MMT) for pain and symptom impact.

METHODS

A systematic review and meta-analysis were conducted. Findings were reported following the 2020 PRISMA statement. Five databases were searched for RCTs. Studies were independently assessed through a standardized form, and their internal validity was evaluated using the Cochrane risk of bias (RoB) tool. Effect sizes (ES) were calculated post-treatment, and the quality of evidence was assessed through GRADE criteria.

RESULTS

Seven articles were included in the review, five of these in the meta-analysis. None of these studies were completely judged at low RoB. MMT was revealed to be not significantly superior for pain reduction [ES: -0.54 (-1.16; 0.08); p = 0.09], for symptom impact [ES: -0.37 (-0.87; 0.13); p = 0.15], and for quality of life [ES: -0.44 (-1.22, 0.33), p = 0.26] compared to standard care. The quality of evidence was "very low". Other results were presented in a qualitative synthesis.

CONCLUSIONS

In patients with CPP/CPPS, MMT is not considered superior to other interventions for pain reduction and symptom impact improvements. However, a positive trend was detected, and we should find confirmation in the future. Further high-quality, double-blinded, sham-controlled RCTs are first necessary to confirm these positive effects and to improve the quality of evidence.

Chondroitin sulfate in therapy osteoarthritis chronic pain patients according to actual clinical recommendations

Of undoubted interest is the search for new drugs comparable in effectiveness to nonsteroidal anti-inflammatory drugs (NSAIDs), but with a safer application profile. NSAIDs are characterized by a good analgesic effect due to the modulation of prostaglandin metabolism by inhibition of cyclooxygenase-2. One of the promising directions of pharmacotherapy of degenerative-dystrophic joint lesions is the use of symptom-modifying drugs of delayed action, which include chondroitin sulfate (CS). CS has antiresorptive activity, anti-inflammatory and anti-inflamaging effects. In addition to the direct effect on pain syndrome severity, he also have a modulating level effect of systemic inflammation of cartilage tissue. According to experts of international and Russian societies, pharmaceutical prescription-quality CS is a basic part of the treatment of osteoarthritis. One of the advantages of CS over NSAIDs is the preservation of the effect for 24 months after the treatment. Against the background of the use of CS, it is possible to reduce the dose or completely cancel NSAIDs, which helps to reduce the frequency of adverse events associated with their intake. CS has a favorable safety profile, which is important for elderly patients and those with comorbid diseases (cardioprotective effects). CS drugs can be administered per orally, intramuscularly, intra-articularly and in combination with different administration methods. Several clinical trials of CS (Chondrogard), including randomized, were conducted in Russia. The Russia Health Ministry approved the appointment of parenteral CS in clinical guidelines: Chronic pain in elderly and senile patients (2020), Falls in elderly and senile patients(2020), "Knee osteoarthritis" (2021), "Hip osteoarthritis" (2021).

International Overview of Somatic Dysfunction Assessment and Treatment in Osteopathic Research: A Scoping Review

BACKGROUND

Osteopathic manipulative treatment (OMT) is a patient-centred, whole-body intervention aimed at enhance the person's self-regulation. OMT interventions are focused on somatic dysfunctions (SD) that can be defined as an altered regulative function associated with inflammatory signs palpable in the body framework in different body regions. The conceptual model that sustains SD, as well as its usefulness for the osteopathic profession, is still being discussed by the osteopathic community. Understanding the role and the application of SD is the aim of this scoping review.

METHODS

A literature search was carried out through the main biomedical databases: Pubmed (Medline), Cochrane, Central (Cochrane), Embase, PEDro and Scopus. Grey literature was considered via Google Scholar and the Osteopathic Research Web. The review was prepared by referring to the "Preferred Reporting Items for Systematic reviews and Meta-Analysis extension for Scoping Reviews" (PRISMA-ScR).

RESULTS

A total of 37,279 records were identified through database searching and other sources. After the duplicates were removed, 27,023 titles and abstracts were screened. A total of 1495 full-text articles were assessed for eligibility. The qualitative synthesis included 280 studies.

CONCLUSIONS

Treating SD is an important part of osteopathic practice that varies from country to country. SD should be considered as a clinical value that assists in the clinical assessment and guides the decision-making process of osteopathic practitioners. Further studies should be designed to better understand why and how to choose the different assessment and intervention modalities to approach SD and to evaluate new osteopathic models.

Do manual therapies have a specific autonomic effect? An overview of systematic reviews

Background

The impact of manual therapy interventions on the autonomic nervous system have been largely assessed, but with heterogeneous findings regarding the direction of these effects. We conducted an overview of systematic reviews to describe if there is a specific autonomic effect elicited by manual therapy interventions, its relation with the type of technique used and the body region where the intervention was applied.

Methods

We conducted an overview according to a publicly registered protocol. We searched the Cochrane Database of Systematic Reviews, MEDLINE, EPISTEMONIKOS and SCOPUS, from their inception to march 2021. We included systematic reviews for which the primary aim of the intervention was to assess the autonomic effect elicited by a manual therapy intervention in either healthy or symptomatic individuals. Two authors independently applied the selection criteria, assessed risk of bias from the included reviews and extracted data. An established model of generalisation guided the data analysis and interpretation.

Results

We included 12 reviews (5 rated as low risk of bias according the ROBIS tool). The findings showed that manual therapies may have an effect on both sympathetic and parasympathetic systems. However, the results from included reviews were inconsistent due to differences in their methodological rigour and how the effects were measured. The reviews with a lower risk of bias could not discriminate the effects depending on the body region to which the technique was applied.

Conclusion

The magnitude of the specific autonomic effect elicited by manual therapies and its clinical relevance is uncertain. We point out some specific recommendations in order to improve the quality and relevance of future research in this field.

Osteopathy and Mental Health: An Embodied, Predictive, and Interoceptive Framework

Globally, mental and musculoskeletal disorders present with high prevalence, disease burden, and comorbidity. In order to improve the quality of care for patients with persistent physical and comorbid mental health conditions, person-centered care approaches addressing psychosocial factors are currently advocated. Central to successful person-centered care is a multidisciplinary collaboration between mental health and musculoskeletal specialists underpinned by a robust therapeutic alliance. Such a collaborative approach might be found in osteopathy, which is typically utilized to treat patients with musculoskeletal disorders but may arguably also benefit mental health outcomes. However, research and practice exploring the reputed effect of osteopathy on patients with mental health problems lack a robust framework. In this hypothesis and theory article, we build upon research from embodied cognition, predictive coding, interoception, and osteopathy to propose an embodied, predictive and interoceptive framework that underpins osteopathic person-centered care for individuals with persistent physical and comorbid mental health problems. Based on the premise that, for example, chronic pain and comorbid depression are underlined by overly precise predictions or imprecise sensory information, we hypothesize that osteopathic treatment may generate strong interoceptive prediction errors that update the generative model underpinning the experience of pain and depression. Thus, physical and mental symptoms may be reduced through active and perceptual inference. We discuss how these theoretical perspectives can inform future research into osteopathy and mental health to reduce the burden of comorbid psychological factors in patients with persistent physical symptoms and support person-centered multidisciplinary care in mental health.

Immediate Effects of Myofascial Release on the Thoracolumbar Fascia and Osteopathic Treatment for Acute Low Back Pain on Spine Shape Parameters: A Randomized, Placebo-Controlled Trial

BACKGROUND

Spine shape parameters, such as leg length and kyphotic or lordotic angle, are influenced by low back pain. There is also evidence that the thoracolumbar fascia plays a role in such pathologies. This study examined the immediate effects of a myofascial release (MFR) technique on the thoracolumbar fascia and of an osteopathic treatment (OMT) on postural parameters in patients with acute low back pain (aLBP).

METHODS

This study was a single-blind randomized placebo-controlled trial. Seventy-one subjects (43.8 ± 10.5 years) suffering from aLBP were randomly and blindedly assigned to three groups to be treated with MFR, OMT, or a placebo intervention. Spinal shape parameters (functional leg length discrepancy (fLLD), kyphotic angle, and lordotic angle) were measured before and after the intervention using video raster stereography.

RESULTS

Within the MFR group, fLLD reduced by 5.2 mm, p < 0.001 and kyphotic angle by 8.2 degrees, p < 0.001. Within the OMT group, fLLD reduced by 4.5 mm, p < 0.001, and kyphotic angle by 8.4°, p = 0.007.

CONCLUSION

MFR and OMT have an influence on fLLD and the kyphotic angle in aLBP patients. The interventions could have a regulating effect on the impaired neuromotor control of the lumbar muscles.

The Challenges and Perspectives of the Integration Between Virtual and Augmented Reality and Manual Therapies

Virtual reality (VR) and augmented reality (AR) have been combined with physical rehabilitation and psychological treatments to improve patients' emotional reactions, body image, and physical function. Nonetheless, no detailed investigation assessed the relationship between VR or AR manual therapies (MTs), which are touch-based approaches that involve the manipulation of tissues for relieving pain and improving balance, postural stability and well-being in several pathological conditions. The present review attempts to explore whether and how VR and AR might be integrated with MTs to improve patient care, with particular attention to balance and to fields like chronic pain that need an approach that engages both mind and body. MTs rely essentially on touch to induce tactile, proprioceptive, and interoceptive stimulations, whereas VR and AR rely mainly on visual, auditory, and proprioceptive stimulations. MTs might increase patients' overall immersion in the virtual experience by inducing parasympathetic tone and relaxing the mind, thus enhancing VR and AR effects. VR and AR could help manual therapists overcome patients' negative beliefs about pain, address pain-related emotional issues, and educate them about functional posture and movements. VR and AR could also engage and change the sensorimotor neural maps that the brain uses to cope with environmental stressors. Hence, combining MTs with VR and AR could define a whole mind-body intervention that uses psychological, interoceptive, and exteroceptive stimulations for rebalancing sensorimotor integration, distorted perceptions, including visual, and body images. Regarding the technology needed to integrate VR and AR with MTs, head-mounted displays could be the most suitable devices due to being low-cost, also allowing patients to follow VR therapy at home. There is enough evidence to argue that integrating MTs with VR and AR could help manual therapists offer patients better and comprehensive treatments. However, therapists need valid tools to identify which patients would benefit from VR and AR to avoid potential adverse effects, and both therapists and patients have to be involved in the development of VR and AR applications to define truly patient-centered therapies. Furthermore, future studies should assess whether the integration between MTs and VR or AR is practically feasible, safe, and clinically useful.
