Osteopathy for primary headache patients: a systematic review

Efficacy of Osteopathic Manipulative Treatment for Pain Reduction in Patients With Patellofemoral Pain Syndrome: A Meta-Analysis of Randomized Controlled Trials

Patellofemoral pain syndrome (PFPS) is among the most common causes of musculoskeletal pain in the United States. It is defined as retropatellar or peripatellar pain that is reproduced with functional activities that load the patellofemoral joint in a flexed position, such as stair climbing or squatting. While it presents in both adolescents and adults, it is commonly found in physically active individuals, such as athletes and military recruits. Exploring the role of osteopathic manipulative treatment (OMT) in PFPS is of particular interest given the absence of a definitive treatment and the poor long-term prognosis associated with PFPS. This meta-analysis includes three studies exploring the use of OMT to reduce pain in patients suffering from PFPS and exploring the efficacy of OMT as a primary intervention. In these studies, pain assessments, pre-treatment, and post-treatment follow-up of at least 30 days were performed using a 10-cm visual analog scale (VAS). The mean difference in pain between OMT and no treatment (NT) groups using the random effects model was -3.95 (-6.39; -1.50) with a p<0.01, suggesting OMT resulted in significant knee pain reduction in those with PFPS. A measure of heterogeneity, known as I2, was found to be high at 97%, which suggests caution should be taken when interpreting the overall results. Given the lack of definitive treatment and the poor long-term prognosis for PFPS, the authors suggest OMT provides an effective option for pain relief in patients with PFPS. Further research is needed to provide results that may be more clinically applicable or valuably interpreted.

How do Australian osteopaths manage migraines? Outcomes from a national practice-based research network

BACKGROUND

Individuals who experience migraines often seek out a variety of treatment options including manual or physical therapy. Evidence suggests that manual therapy, including osteopathy, can play a role in the management of migraines. Whilst there is some literature on the role osteopathy therapy plays in migraine management, none describes the treatment approaches used by practitioners.

OBJECTIVES

To explore the demographic, practice and clinical management characteristics of Australian osteopaths who report treating migraine 'often' in clinical practice.

METHODS

Secondary analysis of a cross-sectional survey of 988 osteopaths from the Osteopathy Research and Innovation Network (ORION), an Australian practice-based research network. Regression analysis was used to identify demographic, practice and clinical management characteristics of Australian osteopaths who reported 'often' treating migraine patients.

RESULTS

Over 40% of respondents (n = 400) indicated treating patients with migraines 'often'. These osteopaths were less likely to be involved in research and be co-located with a dietician compared to osteopaths who do 'not often' treat migraine. Osteopaths who reported 'often' treating migraine were: five times as likely to treat non-English speaking ethnic groups; 2.5 times as likely to treat chronic pain, temporomandibular joint disorders and hand musculoskeletal complaints; compared to those that do not treat migraines 'often'.

CONCLUSION

Australian osteopaths who treat migraine are five times more likely to treat non-English speaking ethnic groups; twice as likely to treat chronic pain; temporomandibular joint disorders, and hand musculoskeletal complaints. More research is needed to identify the practices and patient outcomes associated with osteopathy care for those experiencing migraines.

Potential mechanisms for osteopathic manipulative treatment to alleviate migraine-like pain in female rats

Introduction

Migraines are the leading cause of disability in the United States, and the use of non-pharmaceutical treatments like osteopathic manipulative treatment (OMT) has shown promise. Despite its potential, the lack of mechanistic understanding has hindered widespread adoption. This study aims to investigate the efficacy of OMT in treating acute migraines and unravel its underlying mechanisms of action.

Methods

Female rats were subjected to a "two-hit" approach to induce migraine-like pain. This involved bilateral injections of Complete Freund's Adjuvant (CFA) into the trapezius muscle (1st hit) followed by exposure to Umbellulone, a human migraine trigger, on Day 6 post-CFA (2nd hit). Soft tissue and articulatory techniques were applied to the cervical region for acute abortive or repeated prophylactic treatment. Cutaneous allodynia and trigeminal system activation were assessed through behavioral tests and immunohistochemical staining.

Results

Following Umbellulone inhalation, CFA-primed rats exhibited periorbital and hind paw allodynia. Immediate application of OMT after Umbellulone inhalation as an abortive treatment partially alleviated cutaneous allodynia. With OMT applied thrice as a prophylactic measure, complete suppression of tactile hypersensitivity was observed. Prophylactic OMT also prevented the increase of c-fos signals in the trigeminal nucleus caudalis and the elevation of calcitonin gene-related peptide expression in trigeminal ganglia induced by CFA and Umbellulone exposure at 2 h post-inhalation.

Discussion

These findings provide mechanistic insights into OMT's migraine-relief potential and underscore its viability as a non-pharmacological avenue for managing migraines.

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.

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.

Therapeutic Alliance as Active Inference: The Role of Therapeutic Touch and Biobehavioural Synchrony in Musculoskeletal Care

Touch is recognised as crucial for survival, fostering cooperative communication, accelerating recovery, reducing hospital stays, and promoting overall wellness and the therapeutic alliance. In this hypothesis and theory paper, we present an entwined model that combines touch for alignment and active inference to explain how the brain develops "priors" necessary for the health care provider to engage with the patient effectively. We appeal to active inference to explain the empirically integrative neurophysiological and behavioural mechanisms that underwrite synchronous relationships through touch. Specifically, we offer a formal framework for understanding - and explaining - the role of therapeutic touch and hands-on care in developing a therapeutic alliance and synchrony between health care providers and their patients in musculoskeletal care. We first review the crucial importance of therapeutic touch and its clinical role in facilitating the formation of a solid therapeutic alliance and in regulating allostasis. We then consider how touch is used clinically - to promote cooperative communication, demonstrate empathy, overcome uncertainty, and infer the mental states of others - through the lens of active inference. We conclude that touch plays a crucial role in achieving successful clinical outcomes and adapting previous priors to create intertwined beliefs. The ensuing framework may help healthcare providers in the field of musculoskeletal care to use hands-on care to strengthen the therapeutic alliance, minimise prediction errors (a.k.a., free energy), and thereby promote recovery from physical and psychological impairments.

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.

Osteopathic Care as (En)active Inference: A Theoretical Framework for Developing an Integrative Hypothesis in Osteopathy

Osteopathy is a person-centred healthcare discipline that emphasizes the body’s structure-function interrelationship—and its self-regulatory mechanisms—to inform a whole-person approach to health and wellbeing. This paper aims to provide a theoretical framework for developing an integrative hypothesis in osteopathy, which is based on the enactivist and active inference accounts. We propose that osteopathic care can be reconceptualised under (En)active inference as a unifying framework. Active inference suggests that action-perception cycles operate to minimize uncertainty and optimize an individual’s internal model of the lived world and, crucially, the consequences of their behaviour. We argue that (En)active inference offers an integrative framework for osteopathy, which can evince the mechanisms underlying dyadic and triadic (e.g., in paediatric care) exchanges and osteopathic care outcomes. We propose that this theoretical framework can underpin osteopathic care across the lifespan, from preterm infants to the elderly and those with persistent pain and other physical symptoms. In situations of chronicity, as an ecological niche, the patient-practitioner dyad provides the osteopath and the patient with a set of affordances, i.e., possibilities for action provided by the environment, that through shared intentionally, can promote adaptations and restoration of productive agency. Through a dyadic therapeutic relationship, as they engage with their ecological niche’s affordances—a structured set of affordances shared by agents—osteopath and patient actively construct a shared sense-making narrative and realise a shared generative model of their relation to the niche. In general, touch plays a critical role in developing a robust therapeutic alliance, mental state alignment, and biobehavioural synchrony between patient and practitioner. However, its role is particularly crucial in the fields of neonatology and paediatrics, where it becomes central in regulating allostasis and restoring homeostasis. We argue that from an active inference standpoint, the dyadic shared ecological niche underwrites a robust therapeutic alliance, which is crucial to the effectiveness of osteopathic care. Considerations and implications of this model—to clinical practice and research, both within- and outside osteopathy—are critically discussed.

Effectiveness of cranial osteopathy therapy on nociception in equine back as evaluated by pressure algometry

A horse needs to move in different gaits and carry a rider during riding. Therefore, the equine back must be in a good functional state. Preventing back disorders is one of the keys to ensuring a horse’s health. This study aimed to assess cranial osteopathy therapy as a treatment and prevention method for preventing and reducing back pain. Thirty-two thoroughbred horses were categorised by their backs’ functional status (16 without back pain and 16 with back pain). The mechanical nociceptive threshold was determined before and after osteopathic treatment by an algometer (pain test FPX 100) with pressure points between T14-T15, T18-L1, and L5-L6. The data were analysed with a significance of P < 0.05. The study found that cranial osteopathic therapy raised the mechanical nociceptive threshold average in 83.3% measured points for horses without back pain and in 50% measured points for those with back pain. This study revealed that both horses without back pain and horses with back pain had a positive response to cranial osteopathic therapy, as evidenced by the increased nociceptive threshold limits, indicating that osteopathic therapy can be used as a primary or additional treatment method for back dysfunction.

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.

Manual joint mobilisation techniques, supervised physical activity, psychological treatment, acupuncture and patient education for patients with tension-type headache. A systematic review and meta-analysis

Background

Tension-type headache (TTH) has been ranked the second most prevalent health condition worldwide. Non-pharmacological treatments for TTH are widely used as a supplement or an alternative to medical treatment. However, the evidence for their effects are limited. Therefore, the aim of this study was to review the evidence for manual joint mobilisation techniques, supervised physical activity, psychological treatment, acupuncture and patient education as treatments for TTH on the effect of headache frequency and quality of life.

Methods

A systematic literature search was conducted from February to July 2020 for clinical guidelines, systematic reviews, and individual randomised controlled trials (RCT). The primary outcomes measured were days with headache and quality of life at the end of treatment along with a number of secondary outcomes. Meta-analyses were performed on eligible RCTs and pooled estimates of effects were calculated using the random-effect model. The overall certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation approach (GRADE). In addition, patient preferences were included in the evaluation.

Results

In all, 13 RCTs were included. Acupuncture might have positive effects on both primary outcomes. Supervised physical activity might have a positive effect on pain intensity at the end of treatment and headache frequency at follow-up. Manual joint mobilisation techniques might have a positive effect on headache frequency and quality of life at follow-up. Psychological treatment might have a positive effect on stress symptoms at the end of treatment. No relevant RCTs were identified for patient education. The overall certainty of evidence was downgraded to low and very low. No serious adverse events were reported. A consensus recommendation was made for patient education and weak recommendations for the other interventions.

Conclusion

Based on identified benefits, certainty of evidence, and patient preferences, manual joint mobilisation techniques, supervised physical activity, psychological treatment, acupuncture, and patient education can be considered as non-pharmacological treatment approaches for TTH. Some positive effects were shown on headache frequency, quality of life, pain intensity and stress symptoms. Few studies and low sample sizes posed a challenge in drawing solid conclusions. Therefore, high-quality RCTs are warranted.

Osteopathic empirical research: a bibliometric analysis from 1966 to 2018

Background

Despite the increasing use of osteopathy, a manipulative complementary and alternative medicine therapy, in the general population, its efficacy continues to be debated. In this era of evidence-based practice, no studies have previously reviewed the scientific literature in the field to identify published knowledge, trends and gaps in empirical research. The aims of this bibliometric analysis are to describe characteristics of articles published on the efficacy of osteopathic interventions and to provide an overall portrait of their impacts in the scientific literature.

Methods

A bibliometric analysis approach was used. Articles were identified with searches using a combination of relevant MeSH terms and indexing keywords about osteopathy and research designs in MEDLINE and CINAHL databases. The following indicators were extracted: country of primary author, year of publication, journals, impact factor of the journal, number of citations, research design, participants’ age group, system/body part addressed, primary outcome, indexing keywords and types of techniques.

Results

A total of 389 articles met the inclusion criteria. The number of empirical studies doubled every 5 years, with the United States, Italy, Spain, and United Kingdom being the most productive countries. Twenty-three articles were cited over 100 times. Articles were published in 103 different indexed journals, but more than half (53.7%) of articles were published in one of three osteopathy-focused readership journals. Randomized control trials (n = 145; 37.3%) and case reports (n = 142; 36.5%) were the most common research designs. A total of 187 (48.1%) studies examined the effects of osteopathic interventions using a combination of techniques that belonged to two or all of the classic fields of osteopathic interventions (musculoskeletal, cranial, and visceral).

Conclusion

The number of osteopathy empirical studies increased significantly from 1980 to 2014. The productivity appears to be very much in sync with practice development and innovations; however, the articles were mainly published in osteopathic journals targeting a limited, disciplinary-focused readership.

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.

Osteopathic manipulative medicine in the management of headaches associated with postconcussion syndrome

CONTEXT

Previous studies have demonstrated the effectiveness of osteopathic manipulative treatment (OMT) for various headache types, with limited evidence of its use for headaches related to mild traumatic brain injury (MTBI). No studies prior studies were found regarding OMT for headaches in patients with postconcussion syndrome (PCS), defined as symptom persistence for longer than 3 months after MTBI.

OBJECTIVES

To evaluate OMT for headaches in patients with PCS.

METHODS

A controlled pilot study was conducted of patients with PCS who presented to an outpatient interdisciplinary rehabilitation clinic; patients with symptoms lasting longer than 3 months were enrolled and randomly assigned to an OMT treatment group or a control group. Primary outcome measures were immediate change in headache scores according to a Visual Analog Scale (VAS) and change in the six item Headache Impact Test (HIT-6) between baseline and follow up visits. The participants in the control group completed the HIT-6 between baseline and follow up visits but did not receive OMT and did not complete the VAS. Mean immediate VAS score change for the treatment group and mean improvement in HIT-6 scores for both groups between baseline and follow up were analyzed for statistical significance.

RESULTS

A total of 26 patients were included in this study: 13 (50%) in the treatment group and 13 (50%) in the control group. Six patients (23.1%), three from each group, did not complete the study, so 10 subjects in each group were included in the final analysis. Statistically significant improvement in VAS scores was seen immediately after OMT in the treatment group (mean change, 2.1;p=0.002). Mean HIT-6 scores showed improvement in the treatment group compared with the control group, although the change was not statistically significant (p=0.15) from baseline to follow up visit. No adverse effects from treatments were noted.

CONCLUSIONS

Patients with headaches secondary to PCS showed immediate benefit in headache pain intensity after OMT. However, no sustained benefit was found on the follow up visit compared with the control group.

Osteopathy modulates brain-heart interaction in chronic pain patients: an ASL study

In this study we used a combination of measures including regional cerebral blood flow (rCBF) and heart rate variability (HRV) to investigate brain-heart correlates of longitudinal baseline changes of chronic low back pain (cLBP) after osteopathic manipulative treatment (OMT). Thirty-two right-handed patients were randomised and divided into 4 weekly session of OMT (N = 16) or Sham (N = 16). Participants aged 42.3 ± 7.3 (M/F: 20/12) with cLBP (duration: 14.6 ± 8.0 m). At the end of the study, patients receiving OMT showed decreased baseline rCBF within several regions belonging to the pain matrix (left posterior insula, left anterior cingulate cortex, left thalamus), sensory regions (left superior parietal lobe), middle frontal lobe and left cuneus. Conversely, rCBF was increased in right anterior insula, bilateral striatum, left posterior cingulate cortex, right prefrontal cortex, left cerebellum and right ventroposterior lateral thalamus in the OMT group as compared with Sham. OMT showed a statistically significant negative correlation between baseline High Frequency HRV changes and rCBF changes at T2 in the left posterior insula and bilateral lentiform nucleus. The same brain regions showed a positive correlation between rCBF changes and Low Frequency HRV baseline changes at T2. These findings suggest that OMT can play a significant role in regulating brain-heart interaction mechanisms.

Effect of occipitoatlantal decompression on cerebral blood flow dynamics as evaluated by Doppler ultrasonography

Context

Osteopathic manipulative treatment reduces symptoms in patients with headache disorders, but the underlying mechanisms are unclear.

Objective

To evaluate blood flow in the intracranial and extracranial vasculature before and after occipitoatlantal decompression (OAD) using Doppler ultrasonography.

Methods

Healthy, first-year osteopathic medical students from A.T. Still University's Kirksville College of Osteopathic Medicine participated in a randomized, single-blinded, two-period, two-treatment crossover study. The participants were randomly assigned to 1 of 2 treatment interventions: OAD or sham touch. After one week, participants returned to have the other intervention performed. Blood flow parameters-peak systolic velocity (PSV) and end-diastolic velocity (EDV)-in the middle cerebral artery (MCA), internal carotid artery (ICA), and vertebral artery (VA) were evaluated before, immediately after, 5 minutes after, and 10 minutes after treatment. Differences in PSV, EDV, heart rate (HR), and blood pressure (BP) for both interventions were analyzed for the four time points using mixed-effects models.

Results

Thirty healthy medical students (11 men, 19 women; mean age, 24 years) participated in this study. EDV increased after OAD in the MCA, ICA, and VA (all p<0.001); no change occurred after sham touch (all p>0.05). EDV was greater for all post-treatment timepoints after OAD in the MCA, ICA, and VA than after sham touch (all p<0.001). Although baseline PSV in the MCA measured before treatment was different between treatment interventions (p=0.01), no difference was found between interventions at any post-treatment time point (all p>0.59). Changes in PSV in the ICA and VA and for HR and BP did not depend on treatment intervention (p>0.06).

Conclusion

Increases in EDV occurred in major cranial arteries after OAD but not after sham touch, indicating that OAD improves blood flow to the brain. The exact mechanism of this increase is unknown; however, it can be explained by either parasympathetic stimulation through the secretion of vasodilating neurotransmitters or by a decrease in external tissue pressure on ICA and VA, with the resulting flow causing further dilation in the MCA.

Vertigo and Balance Disorders - The Role of Osteopathic Manipulative Treatment: A Systematic Review

BACKGROUND

Balance disorders are among the most frequent reasons for consultation and referral to specialist care. Osteopathic Manipulative Treatment (OMT) can influence the proprioceptive system by inducing alterations in the proprioceptive stimuli, hence affecting postural control.

OBJECTIVE

The present systematic review aimed to explore the effects of OMT in managing patients with vertigo and balance disorders.

METHODS

MEDLINE (PubMed), ScienceDirect, and Google Scholar were searched. Clinical trials and prospective observational studies were considered. Only studies that considered OMT as the main intervention, provided alone or combined with other interventions, were included. The methodological quality of the evidence was assessed with a modified version of the Newcastle-Ottawa Scale.

RESULTS

Five studies that enrolled a total of 114 subjects met our inclusion criteria. Overall, it has been observed that there is a positive effect on balance disorders through different outcomes in all of the included studies. Only two studies (9 subjects) mentioned low to moderate adverse events after OMT.

CONCLUSIONS

OMT showed weak positive effects on balance function, encouraging the connection of conventional medicine and evidence-based complementary medicine for integrative clinical practice and interprofessional work. However, full-sized adequately powered randomized trials are required to determine the effectiveness of OMT for vertigo and balance disorders.

Brain Connectivity Changes after Osteopathic Manipulative Treatment: A Randomized Manual Placebo-Controlled Trial

The effects of osteopathic manipulative treatment (OMT) on functional brain connectivity in healthy adults is missing in the literature. To make up for this lack, we applied advanced network analysis methods to analyze resting state functional magnetic resonance imaging (fMRI) data, after OMT and Placebo treatment (P) in 30 healthy asymptomatic young participants randomized into OMT and placebo groups (OMTg; Pg). fMRI brain activity measures, performed before (T0), immediately after (T1) and three days after (T2) OMT or P were used for inferring treatment effects on brain circuit functional organization. Repeated measures ANOVA and post-hoc analysis demonstrated that Right Precentral Gyrus (F (2, 32) = 5.995, p < 0.005) was more influential over the information flow immediately after the OMT, while decreased betweenness centrality in Left Caudate (F (2, 32) = 6.496, p < 0.005) was observable three days after. Clustering coefficient showed a distinct time-point and group effect. At T1, reduced neighborhood connectivity was observed after OMT in the Left Amygdala (L-Amyg) (F (2, 32) = 7.269, p < 0.005) and Left Middle Temporal Gyrus (F (2, 32) = 6.452, p < 0.005), whereas at T2 the L-Amyg and Vermis-III (F (2, 32) = 6.772, p < 0.005) increased functional interactions. Data demonstrated functional connectivity re-arrangement after OMT.

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

BACKGROUND

Chronic low back pain (CLBP) is a frequent cause of disability and it represents a medical, social and economic burden globally. Therefore, we assessed effectiveness of osteopathic interventions in the management of NS-CLBP for pain and functional status.

METHODS

A systematic review and meta-analysis were conducted. Findings were reported following the PRISMA statement. Six databases were searched for RCTs. Studies were independently assessed using a standardized form. Each article was assessed using the Cochrane risk of bias (RoB) tool. Effect size (ES) were calculated at post-treatment and at 12 weeks' follow up. We used GRADE to assess quality of evidence.

RESULTS

10 articles were included. Studies investigated osteopathic manipulative treatment (OMT, n = 6), myofascial release (MFR, n = 2), craniosacral treatment (CST, n = 1) and osteopathic visceral manipulation (OVM, n = 1). None of the study was completely judged at low RoB. Osteopathy revealed to be more effective than control interventions in pain reduction (ES: -0.59; 95% CI: -0.81, -0.36; P < 0.00,001) and in improving functional status (ES: -0.42; 95% 95% CI: -0.68, -0.15; P = 0.002). Moderate-quality evidence suggested that MFR is more effective than control treatments in pain reduction (ES: -0.69; 95% CI: -1.05, -0.33; P = 0.0002), even at follow-up (ES: -0.73; 95% CI: -1.09, -0.37; P < 0.0001). Low-quality evidence suggested superiority of OMT in pain reduction (ES: -0.57; 95% CI: -0.90, -0.25; P = 0.001) and in changing functional status (ES: -0.34; 95% CI: -0.65, -0.03; P = 0.001). Very low-quality evidence suggested that MFR is more effective than control interventions in functional improvements (ES: -0.73; 95% CI: -1.25, -0.21; P = 0.006).

CONCLUSION

Results strengthen evidence that osteopathy is effective in pain levels and functional status improvements in NS-CLBP patients. MFR reported better level of evidence for pain reduction if compared to other interventions. Further high-quality RCTs, comparing different osteopathic modalities, are recommended to produce better-quality evidence.

Australian osteopaths as non-medical prescribers: comparison of healthcare practitioner characteristics from a nationally representative survey

The study aimed to compare the characteristics of Australian osteopaths who definitely agree that prescribing scheduled medicines is part of their future scope of practice with those who do not. A secondary analysis of a cross-sectional survey of osteopaths from an Australian practice-based research network was undertaken. Demographic, practice and treatment characteristics were identified using inferential statistics and backward linear regression modelling. Over one-quarter (n=257, 25.9%) of the total participants (n=992) indicated that they 'definitely' agree that osteopaths should seek prescription rights. Adjusted odds ratios (OR) suggested these osteopaths were more likely to engage in medication discussions with patients (OR 1.88), frequently manage migraines (OR 1.68) and seek increased practice rights for referrals to medical specialists (OR 2.61) and diagnostic imaging (OR 2.79). Prescribing as part of the future scope of practice for Australian osteopaths is associated with patient management (medication discussions) and practice characteristics (increased referral rights for specialists and diagnostic imaging) that warrant additional investigation. Understanding of the practice, clinical and patient management characteristics of Australian osteopaths who see prescribing as part of the future scope of practice informs the case for regulatory and health policy changes for prescribing scheduled medicines.

What Makes an Osteopathic Treatment Effective From a Patient's Perspective: A Descriptive Phenomenological Study

OBJECTIVES

This study aimed to describe patients' perspectives on their experience in osteopathic treatment, to contribute toward developing interpretative models on effectiveness.

METHODS

A descriptive phenomenological approach was used. The data were collected through a semistructured interview. To capture the variability of the phenomenon, a purposive sample of 12 participants with previous experience of osteopathic care was selected. The data analysis was carried out in an inductive way, and it was parallel to the recruitment to continuously monitor the data saturation.

RESULTS

Data saturation was reached with 12 participants (female = 9; male = 3). Participants' age ranged from 27 to 82 years old (mean: 55.25 ± 17.15; median: 59; kurtosis: -0.82). Participants had different reasons for consultation. The analysis showed 1 overarching theme, "Osteopathy is a path of awareness," 3 themes, and 12 categories. Themes were: (1) "The experience of pain produces awareness of the need for care," (2) "Osteopathy is a journey to be shared over time," and (3) "The effectiveness of the osteopathic treatment is the discovery of the person's unity by experience."

CONCLUSION

Participants affirm that osteopathy is a path of awareness that starts from an experience of pain; leads them to contact an osteopath; and ends with their experience of the unity of body, mind, and spirit.

Does Osteopathic Manipulative Treatment Induce Autonomic Changes in Healthy Participants? A Thermal Imaging Study

Osteopathic manipulative treatment (OMT) has been demonstrated to be an effective therapy in several clinical conditions and age groups. Despite the clinical effectiveness, lack of robust data in terms of neurobiological, specifically autonomic, mechanisms of action is observed. Preliminary studies showed a parasympathetic effect leading to a trophotropic effect of OMT. However, these data are limited to heart rate variability (HRV) analysis. In order to study further the role of OMT on the autonomic nervous system, a cross-over randomized controlled trial RCT has been designed to test the effect of osteopathic treatment compared to sham therapy on a range of autonomic parameters. Thermal images, HRV and skin conductance data were collected on a sample of healthy adults. The study design consisted of two sessions (OMT and SHAM), 1 treatment per week, lasting 35 min each, composed of 5 min of baseline, 25 min of treatment, and 5 min of post-touch. During the baseline and the post-treatment, participants received no touch. Thirty-seven participants (aged 27 ± 5 years old, male ratio 40%) completed the study. Multivariate analysis showed a significant parasympathetic effect of group as well as of epoch on thermographic data of the nose (estimate 0.38; 95% CI 0.12–0.63; p < 0.01), left (0.17; 0.06–0.27; <0.001) and right (0.16; 0.07–0.24; <0.001) perioral as well as on the forehead (0.07; 0.01–0.12; <0.01) regions but not for the chin (0.08; −0.02 to 0.18; 0.13). Consistent with a parasympathetic effect, analyses demonstrated a difference between OMT and sham groups on the nuHF (p < 0.001) and DFA-a1 (p < 0.01) as well as on skin conductance (<0.01). The present research supports the hypothesis that a single session of OMT as compared to sham induces autonomic consequences in healthy non-symptomatic adults.

Effectiveness of Osteopathic Manipulative Medicine vs Concussion Education in Treating Student Athletes With Acute Concussion Symptoms

CONTEXT

Concussion, a type of mild traumatic brain injury, is a disruption in normal brain function due to head injury. New-onset symptoms from concussion vary, likely depending on the areas of the head and neck affected; they can be severe and debilitating. Current treatment options are limited and difficult to individualize. Osteopathic manipulative medicine (OMM) can aid musculoskeletal restrictions that can potentially improve concussion symptoms.

OBJECTIVE

To assess concussion symptom number and severity in participants with concussion who received either OMM or an educational intervention.

METHODS

A randomized controlled trial was conducted at the New York Institute of Technology Academic Health Care Center. Patients presenting to the center with concussion-like symptoms due to recent head injury within the previous 7 days provided consent and were randomized into 2 intervention groups, receiving either 1 OMM treatment (n=16) or 1 concussion education intervention (n=15). Participants were assessed before and after the intervention with the validated Symptom Concussion Assessment Tool fifth edition (SCAT-5) for quantification of number of symptoms and their severity. Collected data were analyzed using the Mann-Whitney U test and the repeated-measures analysis of variance.

RESULTS

Thirty-one participants were enrolled in the study; after 1 control participant was excluded due to incomplete data, 30 patient records were analyzed. The OMM intervention group had a significant decrease in symptom number (P=.002) and symptom severity (P=.001) compared with the concussion education group.

CONCLUSION

When used in the acute setting, OMM significantly decreased concussion symptom number and severity compared with concussion education. This study demonstrates that integration of OMM using a physical examination-guided, individualized approach is safe and effective in the management of new-onset symptoms of uncomplicated concussions.

Osteopathic Manipulation in the Management of Chronic Pain: Current Perspectives

Chronic pain is a common condition that often interferes with work or other activities. Guidelines support the use of non-pharmacological treatments, such as spinal manipulation, in patients with chronic pain. Osteopathic physicians in the United States are uniquely positioned to manage chronic pain because their professional philosophy embraces the biopsychosocial model and they are trained in the use of osteopathic manipulative treatment (OMT) to complement conventional medical care. This narrative review provides current perspectives on the osteopathic approach to chronic pain management, including evidence for the efficacy of OMT based on systematic searches of the biomedical literature and the ClinicalTrials.gov database. Men, persons with low levels of education, and non-White and Hispanic patients are significantly less likely to have received OMT during their lifetime. Patients with low back and neck pain are most likely to be treated with OMT, and osteopathic manipulative medicine specialty physicians and family medicine physicians most often use OMT. However, many osteopathic physicians report using OMT infrequently. Although OMT is considered safe, based on millions of patient encounters over more than a century, there is limited evidence on its efficacy in treating chronic pain. The lone exception involves chronic low back pain, wherein there is evidence from systematic reviews, a large clinical trial, and observational studies. There is lesser evidence to support cost effectiveness and patient satisfaction associated with OMT for chronic pain. The only clinical practice guideline established by the American Osteopathic Association recommends that OMT should be used to treat chronic low back pain in patients with somatic dysfunction. Given the philosophy of osteopathic medicine, universal training of osteopathic physicians to use OMT, and national guidelines supporting non-pharmacological treatments for chronic pain, it is unclear why OMT use is reported to be remarkably low in physician surveys.

Assessment and Management of Somatic Dysfunctions in Patients With Patellofemoral Pain Syndrome

Context

Patellofemoral pain syndrome (PFPS) is one of the most common determinants of knee pain. The causes of PFPS are multifactorial, and most treatment approaches are conservative. There are many kinds of therapy for this syndrome, which are based on building strength, flexibility, proprioception, and endurance. Training is functional and progression is gradual. Our hypothesis is that total-body osteopathic manipulative therapy (OMTh; manipulative care provided by foreign-trained osteopaths) focused on the management of somatic dysfunctions could be useful for managing the pain of patients with PFPS.

Objective

To investigate the effect of OMTh on pain reduction in patients with PFPS.

Methods

This pilot study was randomized, controlled, and single-blinded with 2 months of follow-up. Qualified participants were randomly assigned to 1 of 2 groups: OMTh group or placebo group. Each participant received either 4 sessions of OMTh or 4 sessions of manual placebo intervention that consisted of passive touching without joint mobilization in a protocolled order. A visual analogue scale (VAS) was used to assess general knee pain, peripatellar pain, pain after prolonged sitting, pain during the patellar compression test, and pain during stair ascent and descent. Pain assessment was performed before the baseline (T0), second (T1), third (T2), and fourth (T3) sessions, and follow-up (T4) was performed 8 weeks after T3.

Results

Thirty-five participants were enrolled the study. The VAS score was significantly reduced and clinically relevant in the OMTh group after each treatment and after 2 months of follow-up. The change in the VAS score before each treatment indicates that the most improved areas at T1 compared with T0 were lumbar and sacral with improvements in 83% and 40% of patients, respectively. At T2 compared with T1, the most improved areas were cervical and sacral with improvements found in 58% and 36% of patients, respectively. The number of dysfunctions that were diagnosed decreased during the baseline to T3 period (40% change). The correlation analysis showed significant results for the dysfunction and the compression test at T2 (P=.01, ρ=0.543).

Conclusion

Significant differences in VAS scores were found between the OMTh and placebo groups. These findings underline how OMTh can lead to reduced pain in patients with PFPS.

Cerebral Perfusion Changes After Osteopathic Manipulative Treatment: A Randomized Manual Placebo-Controlled Trial

Osteopathic Manipulative Treatment (OMT) is a therapeutic approach aimed at enhancing the body's self-regulation focusing on somatic dysfunctions correction. Despite evidence of OMT effectiveness, the underlying neurophysiological mechanisms, as well as blood perfusion effects, are still poorly understood. The study aim was to address OMT effects on cerebral blood flow (CBF) in asymptomatic young volunteers as measured by Magnetic Resonance Arterial Spin Labeling (ASL) method. Thirty blinded participants were randomized to OMT or placebo, and evaluated with an MRI protocol before manual intervention (T0), immediately after (T1), and 3 days later (T2). After T0 MRI, participants received 45 min of OMT, focused on correcting whole body somatic dysfunctions, or placebo manual treatment, consisting of passive touches in a protocolled order. After treatment, participants completed a de-blinding questionnaire about treatment perception. Results show significant differences due to treatment only for the OMT group (OMTg): perfusion decreased (compared to T0) in a cluster comprising the left posterior cingulate cortex (PCC) and the superior parietal lobule, while increased at T2 in the contralateral PCC. Furthermore, more than 60% of participants believed they had undergone OMT. The CBF modifications at T2 suggest that OMT produced immediate but reversible effects on CBF.

Profile of osteopathic practice in Spain: results from a standardized data collection study

Background

There is limited research regarding patients’ profiles and consumer attitudes and habits of osteopathy in Spain. The purpose of this study was to profile patients who regularly receive osteopathic care in Spain using an internationally developed standardized data collection tool.

Method

During the period between April 2014 and December 2015, a UK-developed standardized data collection tool was distributed to Spanish osteopaths who voluntarily agreed to participate in this cross-sectional study.

Results

Thirty-six osteopaths participated in this study and returned a total of 314 completed datasets. Of 314 patients, 61% were women and 39% were men, with a mean age of 40 years (SD 17.02 years, range 0 to 83 years). Forty-four percent were full-time salaried workers, and in 78% of cases, receiving osteopathic treatment was the patient’s own choice. Chronic spinal pain presentations were the most frequent reasons for consultation. Seventy-five percent of patients presented with a coexisting condition, mainly gastrointestinal disorders and headaches. The main treatment approach consisted of mobilization techniques, followed by soft tissue, cranial and high velocity thrust techniques. Improvement or resolution of the complaint was experienced by 93% of patients after a small number of sessions. Adverse events were minor and occurred in 7% of all cases.

Conclusion

This is the first study carried out in Spain analyzing the profile of patients who receive osteopathic care. The typical patient who receives osteopathic care in Spain is middle-aged, presents mainly with chronic spinal pain, and voluntarily seeks osteopathic treatment. Osteopathic treatment produces a significant improvement in the majority of cases with a low rate of minor adverse events reported.

Compression of the Fourth Ventricle Using a Craniosacral Osteopathic Technique: A Systematic Review of the Clinical Evidence

Compression of the fourth ventricle (CV4) is a well-known osteopathic procedure, utilized by osteopaths, osteopathic physicians, craniosacral therapists, physical therapists, and manual therapists as part of their healthcare practice based on some evidence suggesting impact on nervous system functions. The main objective of the study was to identify randomized controlled trials (RCTs) assessing the clinical benefits of CV4 and to show the evidence supporting clinical prescriptions, guides, and advice in treating. A computerized search of the PubMed, CINAHL Complete, Scopus, Web of Science, and ScienceDirect databases was performed. Two filters were used (article type: RCTs; species: humans). The methodological quality of the trials was assessed using the Downs and Black quality checklist for healthcare intervention studies. Only six studies met the inclusion criteria, of which four were RCTs and two were observational studies. The Downs and Black score ranged from 17 to 24 points out of a maximum of 27 points. The present review revealed the paucity of CV4 research in patients with different clinical problems, as five out of six included studies investigated healthy adults. According to the results of the included studies, CV4 may be beneficial for patients with different functional problems.

Assessing and treating primary headaches and cranio-facial pain in patients undergoing rehabilitation for neurological diseases

BACKGROUND

Pain is a very common condition in patient undergoing rehabilitation for neurological disease; however the presence of primary headaches and other cranio-facial pains, particularly when they are actually or apparently independent from the disability for which patient is undergoing rehabilitation, is often neglected. Diagnostic and therapeutic international and national guidelines, as well as tools for the subjective measure of head pain are available and should also be applied in the neurorehabilitation setting. This calls for searching the presence of head pain, independently from the rehabilitation needs, since pain, either episodic or chronic, interferes with patient performance by affecting physical and emotional status. Pain may also interfere with sleep and therefore hamper recovery.

METHODS

In our role of task force of the Italian Consensus Conference on Pain in Neurorehabilitation (ICCPN), we have elaborated specific recommendations for diagnosing and treating head pains in patients undergoing rehabilitation for neurological diseases.

RESULTS AND CONCLUSION

In this narrative review, we describe the available literature that has been evaluated in order to define the recommendations and outline the needs of epidemiological studies concerning headache and other cranio-facial pain in neurorehabilitation.
