Defining adverse events in manual therapies: A modified Delphi consensus study

Acupuncture: A Review of the Safety and Adverse Events and the Strategy of Potential Risk Prevention

Acupuncture is widely accepted as a therapeutic treatment by patients and healthcare providers globally. The safety record has been well established in acupuncture practice although some rare adverse events (AEs) were reported in the literature. While acupuncture-related AEs are generally defined as any undesirable event that occurs in patients during acupuncture treatment that may or may not be associated with the treatment, acupuncture-related adverse reactions (ARs) are defined as any undesirable or harmful reaction induced by trained practitioners practicing acupuncture treatment with standard doses. In this review, we clarify the relationship between AEs and ARs. Furthermore, we compile a list of acupuncture-related AEs reported in systematic reviews and meta-analysis articles. We find that serious acupuncture-related AEs are rare, with serious AEs occurring at a rate of approximately 0.04-0.08 per 10,000 treatments. The most likely serious AEs are pneumothorax, central and peripheral nerve injuries, heart injuries, abdominal organ injuries, infections, and needle breakage. Commonly reported minor AEs include bruising, hematoma, or bleeding at the needling site, as well as vasovagal reactions such as tiredness, dizziness, fainting, or residual pain at insertion points. The analysis identifies contributing factors for serious AEs being deep needle penetration, incorrect acupoint selection, and improper needle manipulation. It also addresses infections caused by contaminated needles, environmental factors, and inadequate skin disinfection. Moreover, other serious AEs, like needle breakage, are mostly due to aggressive manipulation and repeated reheating. Importantly, most acupuncture-related AEs are preventable. To avoid such AEs, acupuncturists in clinical practice should carefully select needling areas, be aware of cautions and contraindications of acupuncture, maintain safe acupuncture depth and hygiene, and strictly adhere to standard operating procedures.

Dry needling perceptions and experiences: A survey of Australian physiotherapists

BACKGROUND

There is a lack of information on the use of dry needling in Australian physiotherapy practice.

OBJECTIVES

Our primary aim was to enhance the understanding of why Australian physiotherapists use dry needling in clinical practice. The secondary aim was to explore Australian physiotherapists experiences with adverse events caused by dry needling.

DESIGN

Cross-sectional online survey.

METHOD

We developed a survey and disseminated it through email to physiotherapists from all states and territories in Australia. Participant demographics and responses were reported as frequencies and percentages.

RESULTS/FINDINGS

We invited 1006 Australian physiotherapists, of which 232 (23%) viewed the online survey and 203 (20%) consented to participate, of which nearly all completed the survey (n = 198, 98%). Most respondents worked in private practice (n = 164, 83%), with 127 (64%) reporting using dry needling as an intervention within the previous 12 months. Physiotherapists typically used dry needling to decrease pain intensity (n = 105, 85%) and reduce muscle tension (n = 100, 81%). Reports of minor adverse events were common and included discomfort during the treatment (n = 77, 62%) and bruising (n = 69, 56%). Some respondents reported experiencing major adverse events including prolonged aggravation of symptoms (n = 10, 8%) and syncope (n = 16, 13%).

CONCLUSIONS

We found that many Australian physiotherapists in private practice use dry needling, usually to decrease pain intensity and muscle tension. Minor adverse events were experienced by more than half the respondents and between 8 and 13% of the Australian physiotherapists surveyed reported experiencing a major adverse event due to dry needling.

Benefits and Harms of Spinal Manipulative Therapy for Treating Recent and Persistent Nonspecific Neck Pain: A Systematic Review With Meta-analysis

OBJECTIVE: We aimed to estimate the benefits and harms of cervical spinal manipulative therapy (SMT) for treating neck pain. DESIGN: Intervention systematic review with meta-analysis of randomized controlled trials (RCTs). LITERATURE SEARCH: We searched the MEDLINE, Cochrane CENTRAL, Embase, CINAHL, PEDro, Chiropractic Literature Index bibliographic databases, and grey literature sources, up to June 6, 2022. STUDY SELECTION CRITERIA: RCTs evaluating SMT compared to guideline-recommended and nonrecommended interventions, sham SMT, and no intervention for adults with neck pain were eligible for our systematic review. Prespecified outcomes included pain, range of motion, disability, health-related quality of life. DATA SYNTHESIS: Random-effects meta-analysis for clinically homogenous RCTs at short-term and long-term outcomes. Risk of bias was assessed using the Cochrane Risk of Bias 2.0 Tool. We used the Grading of Recommendations, Assessment, Development, and Evaluations approach to judge the certainty of evidence. RESULTS: We included 28 RCTs. There was very low to low certainty evidence that SMT was more effective than recommended interventions for improving pain at short term (standardized mean difference [SMD], 0.66; 95% confidence interval [CI]: 0.35, 0.97) and long term (SMD, 0.73; 95% CI: 0.31, 1.16), and for reducing disability at short-term (SMD, 0.95; 95% CI: 0.48, 1.42) and long term (SMD, 0.65; 95% CI: 0.23, 1.06). Transient side effects only were found (eg, muscle soreness). CONCLUSION: There was very low certainty evidence supporting cervical SMT as an intervention to reduce pain and improve disability in people with neck pain.

Initial effect of high-volume mobilisation with movement on shoulder range of motion and pain in patients with rotator cuff-related shoulder pain: protocol for a randomised controlled trial (Evolution Trial)

INTRODUCTION

Mobilisation with movement (MWM) is commonly used for treating patients with rotator cuff-related shoulder pain (RCRSP). However, the evidence supporting MWM efficacy for improving shoulder range of motion (ROM) and pain in patients with RCRSP is limited. It is also unclear whether higher volume MWM leads to better clinical outcomes compared with lower volume MWM in patients with RCRSP. The primary aim of this study is to assess the effect of MWM on the angular onset of pain during shoulder abduction in patients with RCRSP.

METHODS AND ANALYSIS

Sixty participants with RCRSP will be randomised to receive either MWM or sham MWM intervention. The primary outcome is the angular onset of pain during shoulder abduction, and secondary outcomes are pain intensity at the angular onset of pain during shoulder abduction, maximum shoulder ROM, pain intensity during maximum shoulder abduction, pressure pain threshold, mechanical temporal summation, global rating of change scale (GROC) and Brief Pain Inventory-Short Form (BPI-SF). The angular onset of pain and the pain intensity at that range will be assessed at baseline, after 1 set and 3 sets of 10 repetitions of MWM or sham MWM. The GROC will be measured immediately after receiving 3 sets of interventions and on day 3 after interventions. The BPI-SF will be measured on days 1, 3, 5 and 7 after interventions. Other secondary outcomes will be assessed at baseline and after 3 sets of interventions. A linear mixed effects model with a random intercept will be used to compare changes in the outcome measures between MWM and sham MWM interventions.

ETHICS AND DISSEMINATION

This study has been approved by the University of Otago Ethics Committee (Ref. H21/117). Findings from this study will be disseminated through presentations at international and national conferences and will be submitted for publication in a peer-reviewed journal.

Spinal manipulation and adverse event reporting in the pregnant patient limits estimation of relative risk: a narrative review

OBJECTIVE

To describe variability in spinal manipulation technique details and adverse event (AE) documentation of spinal manipulation during pregnancy.

METHODS

Five databases were searched for peer-reviewed investigations of spinal manipulation during pregnancy. Criteria for inclusion was as follows: high velocity, low amplitude thrust manipulation performed, subjects pregnant during manipulation, and English language. Studies were excluded when participants were not currently pregnant, and when the manipulation performed was not high-velocity, low-amplitude thrust. Data extraction included study design, number of participants, gestational age, spinal region, number of manipulations, manipulation technique details, profession of manipulator, AE reporting (Yes vs. No), type, and number of AE.

RESULTS

Out of 18 studies included in the review, only three provide details of the spinal manipulation technique. The reported variables include patient position, practitioner position, and direction of thrust. Fourteen studies documented AE; however, only seven provide AE details.

DISCUSSION

Reporting of spinal manipulation techniques and AE during pregnancy were inconsistent. Replication of methods in future investigations is limited without more detailed documentation of manipulation techniques performed. Furthermore, determining the relative risk and safety of spinal manipulation during pregnancy is not possible without more detailed reporting of AE. Due to these inconsistencies, a checklist is proposed for standardized reporting of spinal manipulation techniques and AE. With more consistent reporting of these parameters, results of future investigations may allow for more definitive and generalizable safety recommendations on spinal manipulation during pregnancy.

Reporting of adverse events associated with spinal manipulation in randomised clinical trials: an updated systematic review

OBJECTIVES

To describe if there has been a change in the reporting of adverse events associated with spinal manipulation in randomised clinical trials (RCTs) since 2016.

DESIGN

A systematic literature review.

DATA SOURCES

Databases were searched from March 2016 to May 2022: MEDLINE (Ovid), Embase, CINAHL, ICL, PEDro and Cochrane Library. The following search terms and their derivatives were adapted for each platform: spinal manipulation; chiropractic; osteopathy; physiotherapy; naprapathy; medical manipulation and clinical trial.

METHODS

Domains of interest (pertaining to adverse events) included: completeness and location of reporting; nomenclature and description; spinal location and practitioner delivering manipulation; methodological quality of the studies and details of the publishing journal. Frequencies and proportions of studies reporting on each of these domains were calculated. Univariable and multivariable logistic regression models were fitted to examine the effect of potential predictors on the likelihood of studies reporting on adverse events.

RESULTS

There were 5399 records identified by the electronic searches, of which 154 (2.9%) were included in the analysis. Of these, 94 (61.0%) reported on adverse events with only 23.4% providing an explicit description of what constituted an adverse event. Reporting of adverse events in the abstract has increased (n=29, 30.9%) while reporting in the results section has decreased (n=83, 88.3%) over the past 6 years. Spinal manipulation was delivered to 7518 participants in the included studies. No serious adverse events were reported in any of these studies.

CONCLUSIONS

While the current level of reporting of adverse events associated with spinal manipulation in RCTs has increased since our 2016 publication on the same topic, the level remains low and inconsistent with established standards. As such, it is imperative for authors, journal editors and administrators of clinical trial registries to ensure there is more balanced reporting of both benefits and harms in RCTs involving spinal manipulation.

Lack of standardization in dry needling dosage and adverse event documentation limits outcome and safety reports: a scoping review of randomized clinical trials

OBJECTIVES

Examine: (1) whether variability in dry needling (DN) dosage affects pain outcomes, (2) if effect sizes are clinically important, and (3) how adverse events (AE) were documented and whether DN safety was determined.

METHODS

Nine databases were searched for randomized controlled trials (RCTs) investigating DN in symptomatic musculoskeletal disorders. Methodological quality was assessed using the Physiotherapy Evidence Database (PEDro) scale. Included RCTs met PEDro criteria #1 and scored > 7/10. Data extraction included DN dosage, pain outcome measures, dichotomous AE reporting (yes/no), and AE categorization. Clinically meaningful differences were determined using the minimum clinically important difference (MCID) for pain outcomes .

RESULTS

Out of 22 identified RCTs, 11 demonstrated significant between-group differences exceeding the MCID, suggesting a clinically meaningful change in pain outcomes. Nine documented whether AE occurred. Only five provided AEs details and four cited a standard means to report AE.

DISCUSSION

There was inconsistency in reporting DN dosing parameters and AE. We could not determine if DN dosing affects outcomes, whether DN consistently produces clinically meaningful changes, or establish optimal dosage. Without more detailed reporting, replication of methods in future investigations is severely limited. A standardized method is lacking to report, classify, and provide context to AE from DN. Without more detailed AE reporting in clinical trials investigating DN efficacy, a more thorough appraisal of relative risk, severity, and frequency was not possible. Based on these inconsistencies, adopting a standardized checklist for reporting DN dosage and AE may improve internal and external validity and the generalizability of results.

Identifying Patient Characteristics Associated With the Occurrence of Post Treatment Non-serious Adverse Events After Cervical Spine Manual Therapy Treatment in Patients With Neck Pain

OBJECTIVES

To compare prevalence rates of serious and non-serious adverse events after manipulation and mobilization and to identify risk factors of serious and non-serious adverse events following 4 types of manual therapy treatment in patients with neck pain.

DESIGN

A prospective cohort study in primary care manual therapy practice.

PARTICIPANTS

Patients with neck pain (N=686) provided data on adverse events after 1014 manipulation treatments, 829 mobilization treatments, 437 combined manipulation and mobilization treatments, and 891 treatments consisting of "other treatment modality".

INTERVENTIONS

Usual care manual therapy.

MAIN OUTCOME MEASURES

A chi-square test was performed to explore differences in prevalence rates. Logistic regression analysis was performed within the 4 treatment groups. A priori we defined associations between patient-characteristics and adverse events of odds ratio (OR)>2 or OR<0.5 as clinically relevant.

RESULTS

No serious adverse events, such as cervical artery dissection or stroke, were reported. With regard to non-serious adverse events, we found that these are common after manual therapy treatment: prevalence rates are ranging from 0.3% to 64.7%. We found a statistically significant difference between the 4 types of treatments, detrimental to mobilization treatment. Logistic regression analysis resulted in 3 main predictors related to non-serious adverse events after manual therapy treatment: smoking (OR ranges from 2.10 [95% confidence interval [CI] 1.37-3.11] to 3.33 [95% CI 1.83-5.93]), the presence of comorbidity (OR ranges from 2.32 [95% CI 1.22-4.44] to 3.88 [95% CI 1.62-9.26]), and female sex (OR ranges from 0.22 [95% CI 0.11-0.46] to 0.49 [95% CI 0.28-0.86]).

CONCLUSION

There is a significant difference in the occurrence of non-serious adverse events after mobilization compared with manipulation or a combination of manipulation and mobilization. Non-serious adverse events in manual therapy practice are common and are associated with smoking and the presence of comorbidity. In addition, women are more likely to report non-serious adverse events.

The influence of manual therapy dosing on outcomes in patients with hip osteoarthritis: a systematic review

OBJECTIVE

To 1) Determine if specific dosing parameters of manual therapy are related to improved pain, disability, and quality of life outcomes in patients with hip osteoarthritis and 2) to provide recommendations for optimal manual therapy dosing based on our findings.

DESIGN

A systematic review of randomized controlled trials from the PubMed, CINAHL, and OVID databases that used manual therapy interventions to treat hip osteoarthritis was performed. Three reviewers assessed the risk of bias for included studies and extracted relevant outcome data based on predetermined criteria. Baseline and follow-up means and standard deviations for outcome measures were used to calculate effect sizes for within and between-group differences.

RESULTS

Ten studies were included in the final analyses totaling 768 participants, and half were graded as high risk of bias. Trends emerged: 1) large effect sizes were seen using long-axis distraction, mobilization and thrust manipulation, 2) mobilization with movement showed large effects for pain and range of motion, and (3) small effects were associated with graded mobilization. Durations of 10 to 30 minutes per session, and frequency 2-3 times per week for 2-6 weeks were the most common dosing parameters.

CONCLUSIONS

There were varied effect sizes associated with pain, function, and quality of life for both thrust and non-thrust mobilizations, and mobilization with movement into hip flexion and internal rotation. Due to the heterogeneity of MT dosage, it is difficult to recommend a specific manual therapy dosage for those with hip osteoarthritis.

Adverse events associated with manual therapy of peripheral joints: A scoping review

METHODS

We performed a systematic review of potential adverse events (AEs) of manual therapy to peripheral joints using PubMed, CINAHL, PEDro, AMED, and Google Scholar with a single term for each peripheral body region (shoulder, elbow, wrist, hand, hip, knee, ankle, foot). Inclusion criteria included articles that examined or reported the occurrence of AEs. Exclusion criteria included literature discussing treatment other than manual therapy or surgery.

RESULTS

Twenty total articles meeting the inclusion criteria were found. A total of fifty-three adverse events were analyzed. Most AEs were benign. Little evidence exists for serious AEs with manual therapy. Scant serious AEs were reported with acupuncture or massage near the shoulder, hip, and knee.

DISCUSSION

AEs with manual therapy to the spine have garnered ample attention in literature. Traditional manual therapy consists of joint mobilization, thrust manipulation, and a variety of soft tissue techniques. However, with the popularity of other "manual therapies", outside the traditional definition, the practitioner and client should be aware of the risks.

CONCLUSION

AEs occurring with most manual therapy techniques to the peripheral joints are transient and mild. It is difficult to attribute true AEs to manual therapy in multi-modal treatment paradigms with numerous single session interventions. Since there are no international definitions or classifications of AEs, and the definition of manual.

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.

Expert consensus on a standardised definition and severity classification for adverse events associated with spinal and peripheral joint manipulation and mobilisation: protocol for an international e-Delphi study

INTRODUCTION

Spinal and peripheral joint manipulation (SMT) and mobilisation (MOB) are widely used and recommended in the best practice guidelines for managing musculoskeletal conditions. Although adverse events (AEs) have been reported following these interventions, a clear definition and classification system for AEs remains unsettled. With many professionals using SMT and MOB, establishing consensus on a definition and classification system is needed to assist with the assimilation of AEs data across professions and to inform research priorities to optimise safety in clinical practice.

METHODS AND ANALYSIS

This international multidisciplinary electronic Delphi study protocol is informed by a scoping review and in accordance with the 'Guidance on Conduction and Reporting Delphi Studies'. With oversight from an expert steering committee, the study comprises three rounds using online questionnaires. Experts in manual therapy and patient safety meeting strict eligibility criteria from the following fields will be invited to participate: clinical, medical and legal practice, health records, regulatory bodies, researchers and patients. Round 1 will include open-ended questions on participants' working definition and/or understanding of AEs following SMT and MOB and their severity classification. In round 2, participants will rate their level of agreement with statements generated from round 1 and our scoping review. In round 3, participants will rerate their agreement with statements achieving consensus in round 2. Statements reaching consensus must meet the a priori criteria, as determined by descriptive analysis. Inferential statistics will be used to evaluate agreement between participants and stability of responses between rounds. Statements achieving consensus in round 3 will provide an expert-derived definition and classification system for AEs following SMT and MOB.

ETHICS AND DISSEMINATION

This study was approved by the Canadian Memorial Chiropractic College Research Ethics Board and deemed exempt by Parker University's Institutional Review Board. Results will be disseminated through scientific, professional and educational reports, publications and presentations.

The efficacy of manual therapy for chronic obstructive pulmonary disease: A systematic review

Background

Manual therapy (MT) can be beneficial in the management of chronic obstructive pulmonary disease (COPD). However, evidence of the efficacy of MT for COPD is not clear. Therefore, we aimed to review the effects of MT, including Chuna, in people diagnosed with COPD.

Methods

MEDLINE via PubMed, EMBASE, The Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Database (CNKI), KoreaMed, Korean Medical Database (KMbase), and Oriental Medicine Advanced Searching Integrated System (OASIS) were searched. Randomized controlled trials (RCTs) and crossover RCTs were included. The main inclusion criteria were COPD diagnosis (forced expiratory volume in the first second [FEV₁]/forced vital capacity [FVC] < 0.70). The primary outcomes were lung function and exercise capacity. The secondary outcomes were symptoms, quality of life (QoL), and adverse event (AE)s. Studies reporting one or both of the primary outcomes were included. The Cochrane RoB 2.0 tool was used to assess the risk of bias. Data synthesis and analysis were conducted according to the trial design.

Results

Of the 2564 searched articles, 13 studies were included. For the primary outcomes, the effect of MT on pulmonary function and exercise capacity in COPD was partly significant but could not be confirmed due to the limited number of studies included in the subgroups. For the secondary outcomes, no definitive evidence regarding the improvement of symptoms and QoL was found, and some minor adverse effects were reported.

Conclusions

There is insufficient evidence to support the role of MT in the management of COPD. High-quality studies are needed to thoroughly evaluate the effect of MT on COPD.

Cannabis in the management of PTSD: a systematic review

Introduction

Existing reviews exploring cannabis effectiveness have numerous limitations including narrow search strategies. We systematically explored cannabis effects on PTSD symptoms, quality of life (QOL), and return to work (RTW). We also investigated harm outcomes such as adverse effects and dropouts due to adverse effects, inefficacy, and all-cause dropout rates.

Methods

Our search in MEDLINE, EMBASE, PsycInfo, CINAHL, Web of Science, CENTRAL, and PubMed databases, yielded 1 eligible RCT and 10 observational studies (n = 4672). Risk of bias (RoB) was assessed with the Cochrane risk of bias tool and ROBINS-I.

Results

Evidence from the included studies was mainly based on non-randomized studies with no comparators. Results from unpooled, high RoB studies showed that cannabis was associated with a reduction in overall PTSD symptoms and improved QOL. Dry mouth, headaches, and psychoactive effects such as agitation and euphoria were the commonly reported adverse effects. In most studies, cannabis was well tolerated, but small proportions of patients experienced a worsening of PTSD symptoms.

Conclusion

Evidence in the current study primarily stems from low quality and high RoB observational studies. Further RCTs investigating cannabis effects on PTSD treatment should be conducted with larger sample sizes and explore a broader range of patient-important outcomes.

Dropout associated with osteopathic manual treatment for chronic noncancerous pain in randomized controlled trials

CONTEXT

Reviews exploring harm outcomes such as adverse effects (AE), all cause dropouts (ACD), dropouts due to inefficacy, and dropouts due to AE associated with osteopathic manipulative treatment (OMT) or osteopathic manual therapy (OMTh) are scant.

OBJECTIVES

To explore the overall AE, ACD, dropouts due to inefficacy, and AE in chronic noncancerous pain (CNCP) patients receiving OMTh through a systematic review of previous literature.

METHODS

For this systematic review and meta-analysis, the authors searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Physiotherapy Evidence Database (PEDro), EMCare, and Allied and Complementary Medicine Database (AMED), and Ostmed.Dr, as well as the bibliographical references of previous systematic reviews evaluating OMTh for pain severity, disability, quality of life, and return to work outcomes. Randomized controlled trials with CNCP patients 18 years or older with OMTh as an active or combination intervention and the presence of a control or combination group were eligible for inclusion. In this sub-study of a previous, larger systematic review, 11 studies (n=1,015) reported data that allowed the authors to perform meta-analyses on ACD and dropouts due to AE. The risk of bias (ROB) was assessed with the Cochrane ROB tool and the quality of evidence was determined with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.

RESULTS

The pooled analysis showed that ACD was not significantly different for visceral OMTh (vOMTh) vs. OMTh control (odds ratio [OR]=2.66 [95% confidence interval [[CI]], 0.28, 24.93]) or for OMTh vs. standard care (OR=1.26 [95% CI, 0.84, 1.89]; I²=0%). Single study analysis showed that OMTh results were nonsignificant in comparison with chemonucleolysis, gabapentin, and exercise. OMTh in combination with gabapentin (vs. gabapentin alone) and OMTh in combination with exercise (vs. exercise alone) showed nonsignificant ACD. Dropouts due to AE were not significantly different, but the results could not be pooled due to an insufficient number of studies.

CONCLUSIONS

Most articles did not explicitly report AEs, ACD rates, or dropouts due to AEs and inefficacy. The limited data available on dropouts showed that OMTh was well tolerated compared with control interventions, and that the ACD and dropouts due to AEs were not significantly different than comparators. Future trials should focus on explicit reporting of dropouts along with beneficial outcomes to provide a better understanding of OMTh efficacy.

The Biomechanical Analysis of Magnitude and Direction of Force by Different Techniques of Thoracic Spinal Manipulation

BACKGROUND

Spinal manipulation (SM) has been widely recognized and used with success in health care fields for spinal joint dysfunction and pain. SM is a procedure that involves small amplitude manipulative thrusts performed with speed. These forces are complex three-dimensional (3-D) forces delivered to create forces and moments at the joint of interest to cause joint movements. The aim of this study was to conduct a 3-dimensional analysis of the magnitude and direction of the forces transmitted in 2 techniques of thoracic spinal manipulation (TSM). Materials/Methods. Thirty-two healthy participants were recruited from the university community. The physical therapist performed TSM using anterior (A) to posterior (P) and P to A techniques once at each of T3, T7, and T12 spinal levels. The magnitude and direction of the forces transmitted during TSM were sensed by the force plates, and the camera system monitored vertebral motion by tracking motion markers.

RESULTS

There were no significant differences on the x-axis while there were significant differences on the y-axis between the measured spinal levels in the P to A technique. There were significant differences found at preload force maximum, preload force minimum, and peak force between T3 and T12 and between T7 and T12 and at peak base force between T7 and T12 on the z-axis. In the A to P technique, there were significant differences in the change of force in measured spinal levels at different axes.

CONCLUSION

These study findings can help therapists better understand the mechanism of TSM and enhance the clinical usefulness of TSM.

Monitoring adverse social and medical events in public health trials: assessing predictors and interpretation against a proposed model of adverse event reporting

Background

Although adverse event (AE) monitoring in trials focusses on medical events, social outcomes may be important in public or social care trials. We describe our approach to reporting and categorising medical and other AE reports, using a case study trial. We explore predictors of medical and social AEs, and develop a model for conceptualising safety monitoring.

Methods

The Building Blocks randomised controlled trial of specialist home visiting recruited 1618 first-time mothers aged 19 years or under at 18 English sites. Event reports collected during follow-up were independently reviewed and categorised as either Medical (standard Good Clinical Practice definition), or Social (trial-specific definition). A retrospectively developed system was created to classify AEs. Univariate analyses explored the association between baseline participant and study characteristics and the subsequent reporting of events. Factors significantly associated at this stage were progressed to binary logistic regressions to assess independent predictors.

Results

A classification system was derived for reported AEs that distinguished between Medical or Social AEs. One thousand, three hundred and fifteen event reports were obtained for mothers or their babies (1033 Medical, 257 Social). Allocation to the trial intervention arm was associated with increased likelihood of Medical rather than Social AE reporting. Poorer baseline psycho-social status predicted both Medical and Social events, and poorer psycho-social status better predicted Social rather than Medical events. Baseline predictors of Social AEs included being younger at recruitment (OR = 0.78 (CI = 0.67 to 0.90), p = 0.001), receiving benefits (OR = 1.60 (CI = 1.09 to 2.35), p = 0.016), and having a higher antisocial behaviour score (OR = 1.22 (CI = 1.09 to 1.36), p < 0.001). Baseline predictors of Medical AEs included having a limiting long-term illness (OR = 1.37 (CI = 1.01 to 1.88), p = 0.046), poorer mental health (OR = 1.03 (CI = 1.01 to 1.05), p = 0.004), and being in the intervention arm of the trial (OR = 1.34 (CI = 1.07 to 1.70), p = 0.012).

Conclusions

Continuity between baseline and subsequent adverse experiences was expected despite potentially beneficial intervention impact. We hypothesise that excess events reported for intervention-arm participants is likely attributable to surveillance bias. We interpreted our findings against a new model that explicates processes that may drive event occurrence, presentation and reporting. Focussing only upon Medical events may miss the well-being and social circumstances that are important for interpreting intervention safety and participant management.

Addition of MoodGYM to physical treatments for chronic low back pain: A randomized controlled trial

Background

Low back pain (LBP) is prevalent, costly and disabling. A biopsychosocial treatment approach involving physical and cognitive behavioural therapy (CBT) is recommended for those with chronic LBP. It is not known if online psychological coaching tools might have a role in the secondary prevention of LBP related disability. To assess the effectiveness of an internet-delivered psychological program (MoodGYM) in addition to standard physical treatment in patients with chronic non-specific LBP at medium risk of ongoing disability.

Methods

A multisite randomized controlled trial was conducted with 108 participants (aged mean 50.4 ± 13.6 years) with chronic LBP attending one of six private physiotherapy or chiropractic clinics. Disability (Roland Morris Disability Questionnaire) and self-efficacy (Patient Self-Efficacy Questionnaire), were assessed at baseline, post-treatment (8-weeks) with follow-up at six- and twelve-months. Participants were randomized into either the intervention group, MoodGYM plus physical treatments, or the control group which received physical treatments alone.

Results

No statistically significant between group differences were observed for either disability at post-treatment (Effect size (standardised mean difference) 95% CI) RMD - 0.06 (- 0.45,0.31), 6-months RMD 0.01 (- 0.38,0.39) and 12-months - 0.20 (- 0.62,0.17) or self-efficacy at post-treatment PSEQ 0.06 (- 0.31,0.45), 6-months 0.02 (- 0.36,0.41) and 12-months 0.21 (- 0.16,0.63).

Conclusion

There was no additional benefit of an internet-delivered CBT program (MoodGYM) to physical treatments in those with chronic non-specific LBP at medium risk of ongoing disability measured at post-treatment, or at 6 and 12 months.

Shared decision making by United Kingdom osteopathic students: an observational study using the OPTION-12 instrument

Background

At the crux of patient centred care is Shared Decision Making (SDM), which benefits patient and practitioner. Despite external pressures, studies indicate that SDM remains poorly practised across a variety of healthcare professions. The degree of SDM engagement within United Kingdom osteopathic undergraduate teaching clinics is currently unknown.

Methods

In 2014 we used the reliable and validated OPTION-12 (O12) instrument to calculate a score that reflected the degree of SDM utility in one United Kingdom Osteopathic Educational Institute’s teaching clinic. We also aimed to compare these scores with those previously obtained for physiotherapists working within the United Kingdom’s National Health Service. Student-patient initial and follow-up encounters were audio recorded, transcribed and scored using the O12. Comparisons between the following O12 scores were performed: the Osteopathic Educational Institute’s 4th and 3rd year students; the Osteopathic Educational Institute’s student’s initial and follow-up patient encounters; the Osteopathic Educational Institute’s students and National Health Service physiotherapists.

Results

We analysed 35.5 h of transcribed data from 30 student-patient encounters (7 initial: 23 follow-up). An O12 score of 0.6% (range 0–10.4%) was calculated. No significant differences were found between year groups or encounter types. Significant differences were found compared to National Health Service physiotherapist (score = 24.4%): (U = 144, z = 4.25, p < 0.0005); although both scores are below the 60% threshold for competent SDM behaviour.

Conclusions

Undergraduate osteopaths did not appear to engage in competent SDM behaviours, implying traditional and paternalistic styles of decision making that align with results from other manual therapy professions. Students in this study did not practise competent SDM behaviours. Effective educational strategies are required to ensure SDM behaviours reach competent levels.

Muscle energy technique for chronic obstructive pulmonary disease: a systematic review

Background

Chronic Obstructive Pulmonary Disease (COPD) is an increasingly prevalent respiratory disease that impacts on daily living. In addition to difficulty breathing, many people experience extrapulmonary comorbidities such as musculoskeletal disorders. Pulmonary rehabilitation can improve fitness and strength but may be difficult for patients with musculoskeletal disorders. Recent research indicates promising benefits of adding manual therapy to standard care to improve clinical outcomes.

Objectives

To evaluate the efficacy and safety of Muscle Energy Technique (MET) for people with COPD.

Methods

Ten databases were searched from inceptions to May 2018. Eligible studies were randomised controlled trials assessing MET compared to any control for COPD. Outcomes included lung function, exercise capacity, health-related quality of life, and adverse events.

Results

Three randomised controlled trials assessing 90 participants were included. The quality of the research was limited by reporting of outcome measures and results, varying treatment protocols, and small sample sizes. Results from one study showed that pulmonary function was not statistically different between groups at end of treatment (FEV1% MD 4.87%; 95% CI - 0.79 to 10.53). Exercise capacity and perceived dyspnoea ratings were improved in single studies. Adverse events were unrelated to the MET intervention.

Conclusions

The use of MET for COPD is an emerging field of research, with few studies evaluating its efficacy and safety. Currently, there is insufficient evidence to support the use of MET in the management of COPD. Rigorously designed studies with larger sample sizes are needed to better understand the role of MET for COPD.

A Binational Need Assessment to Define the Level of Endovascular Expertise Required by Vascular Surgical Trainees

BACKGROUND

There has been a shift toward competency-based surgical education programs to improve trainee performance and achieve better patient outcomes. Endovascular procedures comprise a significant volume of vascular surgery, but the current methods for assessing the endovascular competence of vascular trainees in Australia and New Zealand are suboptimal. The objective of this study was to perform a need assessment to define the scope of endovascular expertise required by vascular surgical trainees to later aid in the development of novel surgical training assessment tools.

METHODS

A modified Delphi method was used to achieve expert consensus. Fifty-three key stakeholders in vascular surgical education and training (SET) in Australia and New Zealand were invited to take part in the 2-stage survey. Experts were asked which procedures they considered to be requisite for vascular surgery trainees and at which SET level competence should be achieved. The results were reiterated to the expert panel in the second stage, and consensus considered achieved if over 75% of experts were in agreement.

RESULTS

In the first stage 25 experts reached consensus that competence in 18 of the 26 procedures should be requisite for SET trainees. Twenty-two experts responded to the second stage and consensus was achieved for 12 out of 14 of the procedural items with mean percentage of experts in agreement being 90%.

CONCLUSIONS

A need assessment using a modified Delphi method has achieved consensus among experts in vascular surgery regarding the endovascular procedures considered to be requisite for vascular surgery trainees in Australia and New Zealand.

Do adverse events after manual therapy for back and/or neck pain have an impact on the chance to recover? A cohort study

Background

Manual therapy is a commonly used treatment for patients with back and neck pain. Studies have shown that manual therapy-related adverse events are mainly short in duration and mild or moderate by their intensity, affecting up to 50% of the patients. If the presence of adverse events has an impact on the chance to recover from back/neck pain is poorly understood. The aim of this study was to investigate if mild or moderate adverse events after manual therapy has an impact on the chance to recover from back/neck pain in men and women.

Methods

A prospective cohort study of 771 patients with at least three treatment sessions in a randomized controlled trial performed in January 2010 – December 2013. Adverse events within 24 h after each treatment were measured with questionnaires and categorized as: no, mild or moderate, based on bothersomeness. Outcome measure was the perceived recovery at seven weeks and at three months follow-up. Odds Ratios (OR) and 95% confidence intervals (CI) were calculated by Logistic regression to investigate the associations between the exposure and outcome, and to test and adjust for potential confounding.

Results

There were no statistically significant associations observed between the experience of mild or moderate adverse events and being recovered at the seven weeks follow-up. The only statistically significant association observed at the three months follow-up was for mild adverse events in men with an OR of 2.44, 95% CI: 1.24–4.80 in comparison to men with no adverse events.

Conclusion

This study indicates that mild adverse events after manual therapy may be related to a better chance to recover in men.

Trial registration

The study is based on data from a trial registered in Current Controlled Trials (ISRCTN92249294).

Thoracic spine manipulation for the management of mechanical neck pain: A systematic review and meta-analysis

Objective

To investigate the role of thoracic spine manipulation (TSM) on pain and disability in the management of mechanical neck pain (MNP).

Data sources

Electronic databases PubMed, CINAHL, Pedro, Embase, AMED, the Cochrane Library, and clinicaltrials.gov were searched in January 2018.

Study selection

Eligible studies were completed RCTs, written in English, had at least 2 groups with one group receiving TSM, had at least one measure of pain or disability, and included patients with MNP of any duration. The search identified 1717 potential articles, with 14 studies meeting inclusion criteria.

Study appraisal and synthesis methods

Methodological quality was evaluated independently by two authors using the guidelines published by the Cochrane Collaboration. Pooled analyses were analyzed using a random-effects model with inverse variance methods to calculate mean differences (MD) and 95% confidence intervals for pain (VAS 0-100mm, NPRS 0-10pts; 0 = no pain) and disability (NDI and NPQ 0–100%; 0 = no disability).

Results

Across the included studies, there was increased risk of bias for inadequate provider and participant blinding. The GRADE approach demonstrated an overall level of evidence ranging from very low to moderate. Meta-analysis that compared TSM to thoracic or cervical mobilization revealed a significant effect favoring the TSM group for pain (MD -13.63; 95% CI: -21.79, -5.46) and disability (MD -9.93; 95% CI: -14.38, -5.48). Meta-analysis that compared TSM to standard care revealed a significant effect favoring the TSM group for pain (MD -13.21; 95% CI: -21.87, -4.55) and disability (MD -11.36; 95% CI: -18.93, -3.78) at short-term follow-up, and a significant effect for disability (MD -4.75; 95% CI: -6.54, -2.95) at long-term follow-up. Meta-analysis that compared TSM to cervical spine manipulation revealed a non-significant effect (MD 3.43; 95% CI: -7.26, 14.11) for pain without a distinction between immediate and short-term follow-up.

Limitations

The greatest limitation in this systematic review was the heterogeneity among the studies making it difficult to assess the true clinical benefit, as well as the overall level of quality of evidence.

Conclusions

TSM has been shown to be more beneficial than thoracic mobilization, cervical mobilization, and standard care in the short-term, but no better than cervical manipulation or placebo thoracic spine manipulation to improve pain and disability.

Effectiveness of manual therapy in COPD: A systematic review of randomised controlled trials

PURPOSE

Manual therapy (MT) has been proposed in pulmonary rehabilitation programmes for patients with chronic obstructive pulmonary disease (COPD), but an updated systematic review of the evidence is lacking. We aimed to systematically review the effectiveness of MT interventions, alone or added to exercise, on lung function, exercise capacity and quality of life in COPD patients, compared to other therapies (e.g. exercise alone) or no treatment.

MATERIALS AND METHODS

We searched MEDLINE, EMBASE, Physiotherapy Evidence Database, and Cochrane Central Register of Controlled Trials databases, using the terms: COPD, manual therapy, manipulation, joint mobilisation, osteopathic manipulation. Only randomised controlled trials (RCT) were considered.

RESULTS

Out of 555 articles screened, 6 fulfilled the inclusion criteria. The study designs were heterogeneous (with different intervention schedules) and there was a high risk of bias. No effect on lung function was found, while results on exercise capacity were contrasting. MT had no effect on quality of life, although valid measures were available only in one study. Only mild adverse events were reported.

CONCLUSIONS

Few RCTs of poor methodological quality are available on the effects of MT in COPD. More and better quality RCTs are needed before this technique can be included in rehabilitation programmes for these patients.

Knowledge and pre-thoracic spinal thrust manipulation examination: a survey of current practice in the UK

OBJECTIVES

The perceived relative safety of thoracic thrust joint manipulation (TTJM) has contributed to evidence supporting its use. Yet, TTJM is not without risk, where transient side effects (SE) and severe adverse events (AE) have been documented. With evidence supporting the importance of prethrust examination in reducing AE in other spinal regions this study investigated TTJM knowledge and pre-TTJM examination. Method: An e-survey, informed by existing evidence and expertise was designed and piloted. Eligibility criteria: UK-trained physiotherapists who use TTJM. Recruitment via professional networks and social media from December 2016 to February 2017. Data analysis included descriptive analyses (means, standard deviation and frequencies/central tendencies), and content analysis (themes and frequencies) for free text data. Results: From 306 responses, the sample comprised 146 (53%) males, mean (SD) age 36.37(8.68) years, with 12.88(8.67) years in practice, 11.07(8.14) years specialization, working in National Health Service/private practice (81%) and performing 0-5 TTJM/week (86%).

EXAMINATION

40% (n = 83) utilized pre-TTJM examination with 45% (n = 139) adapting the examination for different regions. Technique selection and effect: preferred technique was prone rotational TTJM (67%). Perception of the primary underlying effect was neurophysiological (54%), biomechanical (45%) or placebo (1%). Knowledge: Levels of agreement were found for contraindications (85%), precautions (75%), and red flags (86%) with more variability for risks including AE and SE (61%).

DISCUSSION

UK physiotherapists demonstrated good knowledge and agreement of contraindications, precautions, and red flags to TTJM. With <50% respondents utilizing pre-TTJM examination, variable knowledge of TTJM risks, and therapeutic effects of TTJM further research is required.

Singing for people with aphasia (SPA): a protocol for a pilot randomised controlled trial of a group singing intervention to improve well-being

INTRODUCTION

The singing for people with aphasia (SPA) intervention aims to improve quality of life and well-being for people with poststroke aphasia. A definitive randomised controlled trial (RCT) is required to assess the clinical and cost effectiveness of SPA. The purpose of this pilot study is to assess the feasibility of such a definitive trial and inform its design.

METHODS AND ANALYSIS

A two-group, assessor-blinded, randomised controlled external pilot trial with parallel mixed methods process evaluation and economic evaluation. Forty-eight participants discharged from clinical speech and language therapy will be individually randomised 1:1 to SPA (10 group sessions plus a resource booklet) or control (resource booklet only). Outcome assessment at baseline, 3 and 6 months postrandomisation include: ICEpop CAPability measure for adults, Stroke and Aphasia Quality of Life, EQ-5D-5L, modified Reintegration into Normal Living Index, Communication Outcome After Stroke, Very Short Version of the Minnesota Aphasia Test, Service Receipt Inventory and Care Related Quality of Life. Feasibility, acceptability and process outcomes include recruitment and retention rates, with measurement burden and trial experiences being explored in qualitative interviews (15 participants, 2 music facilitators and 2 music champions). Analyses include: descriptive statistics, with 95% CIs where appropriate; qualitative themes; intervention fidelity from videos and session checklists; rehearsal of health economic analysis.

ETHICS AND DISSEMINATION

NHS National Research Ethics Service and the Health Research Authority confirmed approval in April 2017; recruitment commenced in June 2017. Outputs will include: pilot data to inform whether to proceed to a definitive RCT and support a funding application; finalised intervention manual for multicentre replication of SPA; presentations at conferences, public involvement events; internationally recognised peer reviewed journal publications, open access sources and media releases.

Community-based rehabilitation training after stroke: results of a pilot randomised controlled trial (ReTrain) investigating acceptability and feasibility

OBJECTIVES

To assess acceptability and feasibility of trial processes and the Rehabilitation Training (ReTrain) intervention including an assessment of intervention fidelity.

DESIGN

A two-group, assessor-blinded, randomised controlled trial with parallel mixed methods process and economic evaluations.

SETTING

Community settings across two sites in Devon.

PARTICIPANTS

Eligible participants were: 18 years old or over, with a diagnosis of stroke and with self-reported mobility issues, no contraindications to physical activity, discharged from National Health Service or any other formal rehabilitation programme at least 1 month before, willing to be randomised to either control or ReTrain and attend the training venue, possessing cognitive capacity and communication ability sufficient to participate. Participants were individually randomised (1:1) via a computer-generated randomisation sequence minimised for time since stroke and level of functional disability. Only outcome assessors independent of the research team were blinded to group allocation.

INTERVENTIONS

ReTrain comprised (1) an introductory one-to-one session; (2) ten, twice-weekly group classes with up to two trainers and eight clients; (3) a closing one-to-one session, followed by three drop-in sessions over the subsequent 3 months. Participants received a bespoke home-based training programme. All participants received treatment as usual. The control group received an exercise after stroke advice booklet.

OUTCOME MEASURES

Candidate primary outcomes included functional mobility and physical activity.

RESULTS

Forty-five participants were randomised (ReTrain=23; Control=22); data were available from 40 participants at 6 months of follow-up (ReTrain=21; Control=19) and 41 at 9 months of follow-up (ReTrain=21; Control=20). We demonstrated ability to recruit and retain participants. Participants were not burdened by the requirements of the study. We were able to calculate sample estimates for candidate primary outcomes and test procedures for process and health economic evaluations.

CONCLUSIONS

All objectives were fulfilled and indicated that a definitive trial of ReTrain is feasible and acceptable.

What are the risks of manual treatment of the spine? A scoping review for clinicians

Background

Communicating to patients the risks of manual treatment to the spine is an important, but challenging element of informed consent. This scoping review aimed to characterise and summarise the available literature on risks and to describe implications for clinical practice and research.

Method

A methodological framework for scoping reviews was followed. Systematic searches were conducted during June 2017. The quantity, nature and sources of literature were described. Findings of included studies were narratively summarised, highlighting key clinical points.

Results

Two hundred and fifty articles were included. Cases of serious adverse events were reported. Observational studies, randomised studies and systematic reviews were also identified, reporting both benign and serious adverse events.Benign adverse events were reported to occur commonly in adults and children. Predictive factors for risk are unclear, but for neck pain patients might include higher levels of neck disability or cervical manipulation. In neck pain patients benign adverse events may result in poorer short term, but not long term outcomes.Serious adverse event incidence estimates ranged from 1 per 2 million manipulations to 13 per 10,000 patients. Cases are reported in adults and children, including spinal or neurological problems as well as cervical arterial strokes. Case-control studies indicate some association, in the under 45 years age group, between manual interventions and cervical arterial stroke, however it is unclear whether this is causal. Elderly patients have no greater risk of traumatic injury compared with visiting a medical practitioner for neuro-musculoskeletal problems, however some underlying conditions may increase risk.

Conclusion

Existing literature indicates that benign adverse events following manual treatments to the spine are common, while serious adverse events are rare. The incidence and causal relationships with serious adverse events are challenging to establish, with gaps in the literature and inherent methodological limitations of studies. Clinicians should ensure that patients are informed of risks during the consent process. Since serious adverse events could result from pre-existing pathologies, assessment for signs or symptoms of these is important. Clinicians may also contribute to furthering understanding by utilising patient safety incident reporting and learning systems where adverse events have occurred.

Predictive factors for reporting adverse events following spinal manipulation in randomized clinical trials - secondary analysis of a systematic review

While spinal manipulative therapy (SMT) is recommended for the treatment of spinal disorders, concerns exist about adverse events associated with the intervention. Adequate reporting of adverse events in clinical trials would allow for more accurate estimations of incidence statistics through meta-analysis. However, it is not currently known if there are factors influencing adverse events reporting following SMT in randomized clinical trials (RCTs). Thus our objective was to investigate predictive factors for the reporting of adverse events in published RCTs involving SMT. The Physiotherapy Evidence Database (PEDro) and Cochrane Central Register of Controlled Trials (CENTRAL) were searched for RCTs involving SMT. Domains of interest included: sample size; publication date relative to the 2010 CONSORT statement; risk of bias; the region treated; and number of intervention sessions. 7398 records were identified, of which 368 articles were eligible for inclusion. A total of 140 (38.0%) articles reported on adverse events. Articles were more likely to report on adverse events if they possessed larger sample sizes, were published after the 2010 CONSORT statement, had a low risk of bias and involved multiple intervention sessions. The region treated was not a significant predictor for reporting on adverse events. Predictors for reporting on adverse events included larger sample size, publication after the 2010 CONSORT statement, low risk of bias and trials involving multiple intervention sessions. We recommend that researchers focus on developing robust methodologies and participant follow-up regimens for RCTs involving SMT.

Adverse effects as a consequence of being the subject of orthopaedic manual therapy training, a worldwide retrospective survey

BACKGROUND

Physical therapists (PTs) use a range of manual therapy techniques developed to an advanced level through postgraduate orthopaedic manipulative physical therapy (OMPT) programmes. The aim of this study was to describe the adverse effects experienced by students after having techniques performed on them as part of their OMPT training.

DESIGN

A descriptive online survey of current students and recent graduates (≤5 years)m of OMPT programmes across the 22 Member Organisations of the International Federation of Orthopaedic Manipulative Physical Therapists.

RESULTS

The questionnaire was completed by 1640 respondents across 22 countries (1263 graduates, 377 students. Some 60% of respondents reported never having experienced adverse effects during their manual therapy training. Of the 40% who did, 66.4% reported neck pain, 50.9% headache and 32% low back pain. Most reports of neck pain started after a manipulation and/or mobilisation, of which 53.4% lasted ≤24 h, 38.1% > 24 h but <3 months and 13.7% still experienced neck pain to date. A small percentage of respondents (3.3%) reported knowing of a fellow student experiencing a major adverse effect.

CONCLUSION

Mild to moderate adverse effects after practising manual therapy techniques are commonly reported, but usually resolve within 24 h. However, this survey has identified the reported occurrence of major adverse effects that warrant further investigation.

Adverse events following cervical manipulative therapy: consensus on classification among Dutch medical specialists, manual therapists, and patients

Objectives

To obtain consensus-based agreement on a classification system of adverse events (AE) following cervical spinal manipulation. The classification system should be comprised of clear definitions, include patients' and clinicians' perspectives, and have an acceptable number of categories.

Methods

Design: A three-round Delphi study. Participants: Thirty Dutch participants (medical specialists, manual therapists, and patients) participated in an online survey. Procedure: Participants inventoried AE and were asked about their preferences for either a three- or a four-category classification system. The identified AE were classified by two analysts following the International Classification of Functioning, Disability and Health (ICF), and the International Classification of Diseases and Related Health Problems (ICD-10). Participants were asked to classify the severity for all AE in relation to the time duration.

Results

Consensus occurred in a three-category classification system. There was strong consensus for 16 AE in all severities (no, minor, and major AE) and all three time durations [hours, days, weeks]. The 16 AE included anxiety, flushing, skin rash, fainting, dizziness, coma, altered sensation, muscle tenderness, pain, increased pain during movement, radiating pain, dislocation, fracture, transient ischemic attack, stroke, and death. Mild to strong consensus was reached for 13 AE.

Discussion

A consensus-based classification system of AE is established which includes patients' and clinicians' perspectives and has three categories. The classification comprises a precise description of potential AE in accordance with internationally accepted classifications. After international validation, clinicians and researchers may use this AE classification system to report AE in clinical practice and research.

Manual therapy compared with physical therapy in patients with non-specific neck pain: a randomized controlled trial

Background

Manual therapy according to the School of Manual Therapy Utrecht (MTU) is a specific type of passive manual joint mobilization. MTU has not yet been systematically compared to other manual therapies and physical therapy. In this study the effectiveness of MTU is compared to physical therapy, particularly active exercise therapy (PT) in patients with non-specific neck pain.

Methods

Patients neck pain, aged between 18–70 years, were included in a pragmatic randomized controlled trial with a one-year follow-up. Primary outcome measures were global perceived effect and functioning (Neck Disability Index), the secondary outcome was pain intensity (Numeric Rating Scale for Pain). Outcomes were measured at 3, 7, 13, 26 and 52 weeks. Multilevel analyses (intention-to-treat) were the primary analyses for overall between-group differences. Additional to the primary and secondary outcomes the number of treatment sessions of the MTU group and PT group was analyzed. Data were collected from September 2008 to February 2011.

Results

A total of 181 patients were included. Multilevel analyses showed no statistically significant overall differences at one year between the MTU and PT groups on any of the primary and secondary outcomes. The MTU group showed significantly lower treatment sessions compared to the PT group (respectively 3.1 vs. 5.9 after 7 weeks; 6.1 vs. 10.0 after 52 weeks).

Conclusions

Patients with neck pain improved in both groups without statistical significantly or clinically relevant differences between the MTU and PT groups during one-year follow-up.

Adverse events associated with the use of cervical spine manipulation or mobilization and patient characteristics: A systematic review

Cervical spinal manipulation (CSM) and cervical mobilization are frequently used in patients with neck pain and headache. Pre-manipulative cervical instability and arterial integrity tests appear to be unreliable in identifying patients at risk for adverse events. It would be valuable if patients at risk could be identified by specific characteristics during the preliminary screening. Objective was to identify characteristics of 1) patients, 2) practitioners, 3) treatment process and 4) adverse events (AE) occurring after CSM or cervical mobilization. A systematic search was performed in PubMed, Embase, CINAHL, Web-of-science, AMED, and ICL (Index Chiropractic Literature) up to December 2014. Of the initial 1043 studies, 144 studies were included, containing 227 cases. 117 cases described male patients with a mean age of 45 (SD 12) and a mean age of 39 (SD 11) for females. Most patients were treated by chiropractors (66%). Manipulation was reported in 95% of the cases, and neck pain was the most frequent indication. Cervical arterial dissection (CAD) was reported in 57% (P = 0.21) of the cases and 45.8% had immediate onset symptoms. The overall distribution of gender for CAD is 55% (n = 71) for female and therefore opposite of the total AE. Patient characteristics were described poorly. No clear patient profile, related to the risk of AE after CSM, could be extracted. However, women seem more at risk for CAD. There seems to be under-reporting of cases. Further research should focus on a more uniform and complete registration of AE using standardized terminology.

Assignment of adverse event indexing terms in randomized clinical trials involving spinal manipulative therapy: an audit of records in MEDLINE and EMBASE databases

Background

Reporting of adverse events in randomized clinical trials (RCTs) is encouraged by the authors of The Consolidated Standards of Reporting Trials (CONSORT) statement. With robust methodological design and adequate reporting, RCTs have the potential to provide useful evidence on the incidence of adverse events associated with spinal manipulative therapy (SMT). During a previous investigation, it became apparent that comprehensive search strategies combining text words with indexing terms was not sufficiently sensitive for retrieving records that were known to contain reports on adverse events. The aim of this analysis was to compare the proportion of articles containing data on adverse events associated with SMT that were indexed in MEDLINE and/or EMBASE and the proportion of those that included adverse event-related words in their title or abstract.

Methods

A sample of 140 RCT articles previously identified as containing data on adverse events associated with SMT was used. Articles were checked to determine if: (1) they had been indexed with relevant terms describing adverse events in the MEDLINE and EMBASE databases; and (2) they mentioned adverse events (or any related terms) in the title or abstract.

Results

Of the 140 papers, 91% were MEDLINE records, 85% were EMBASE records, 81% were found in both MEDLINE and EMBASE records, and 4% were not in either database. Only 19% mentioned adverse event-related text words in the title or abstract. There was no significant difference between MEDLINE and EMBASE records in the proportion of available papers (p = 0.078). Of the 113 papers that were found in both MEDLINE and EMBASE records, only 3% had adverse event-related indexing terms assigned to them in both databases, while 81% were not assigned an adverse event-related indexing term in either database.

Conclusions

While there was effective indexing of RCTs involving SMT in the MEDLINE and EMBASE databases, there was a failure of allocation of adverse event indexing terms in both databases. We recommend the development of standardized definitions and reporting tools for adverse events associated with SMT. Adequate reporting of adverse events associated with SMT will facilitate accurate indexing of these types of manuscripts in the databases.

A prospective 2-site parallel intervention trial of a research-based film to increase exercise amongst older hemodialysis patients

Background

Evidence suggests that exercise training for hemodialysis patients positively improves morbidity and mortality outcomes, yet exercise programs remain rare and are not systematically incorporated into care. We developed a research-based film, Fit for Dialysis, designed to introduce, motivate, and sustain exercise for wellness amongst older hemodialysis patients, and exercise counseling and support by nephrologists, nurses, and family caregivers. The objective of this clinical trial is to determine whether and in what ways Fit for Dialysis improves outcomes and influences knowledge/attitudes regarding the importance of exercise for wellness in the context of end-stage renal disease.

Methods/Design

This 2-site parallel intervention trial will recruit 60 older hemodialysis patients from two urban hospitals. The trial will compare the film + a 16-week exercise program in one hospital, with a 16-week exercise-only program in another hospital. Physical fitness and activity measures will be performed at baseline, 8 and 16 weeks, and 12 weeks after the end of the program. These include the 2-min Walk Test, Grip Strength, Duke Activity Status Index, and the Timed Up-and-Go Test, as well as wearing a pedometer for one week. Throughout the 16-week exercise program, and at 12 weeks after, we will record patients’ exercise using the Godin Leisure-time Exercise Questionnaire. Patients will also keep a diary of the exercise that they do at home on non-dialysis days. Qualitative interviews, conducted at baseline, 8, and 16 weeks, will explore the impact of Fit for Dialysis on the knowledge/attitudes of patients, family caregivers, and nephrology staff regarding exercise for wellness, and in what ways the film is effective in educating, motivating, or sustaining patient exercise during dialysis, at home, and in the community.

Discussion

This research will determine for whom Fit for Dialysis is effective, why, and under what conditions. If Fit for Dialysis is proven beneficial to patients, nephrology staff and family caregivers, research-based film as a model to support exercise promotion and adherence could be used to support the National Kidney Foundation’s guideline recommendation (NKF-KDOQI) that exercise be incorporated into the care and treatment of dialysis patients.

Community-based Rehabilitation Training after stroke: protocol of a pilot randomised controlled trial (ReTrain)

INTRODUCTION

The Rehabilitation Training (ReTrain) intervention aims to improve functional mobility, adherence to poststroke exercise guidelines and quality of life for people after stroke. A definitive randomised controlled trial (RCT) is required to assess the clinical and cost-effectiveness of ReTrain, which is based on Action for Rehabilitation from Neurological Injury (ARNI). The purpose of this pilot study is to assess the feasibility of such a definitive trial and inform its design.

METHODS AND ANALYSIS

A 2-group, assessor-blinded, randomised controlled external pilot trial with parallel mixed-methods process evaluation and economic evaluation. 48 participants discharged from clinical rehabilitation despite residual physical disability will be individually randomised 1:1 to ReTrain (25 sessions) or control (exercise advice booklet). Outcome assessment at baseline, 6 and 9 months include Rivermead Mobility Index; Timed Up and Go Test; modified Patient-Specific Functional Scale; 7-day accelerometry; Stroke Self-efficacy Questionnaire, exercise diary, Fatigue Assessment Scale, exercise beliefs and self-efficacy questionnaires, SF-12, EQ-5D-5L, Stroke Quality of Life, Carer Burden Index and Service Receipt Inventory. Feasibility, acceptability and process outcomes include recruitment and retention rates; with measurement burden and trial experiences being explored in qualitative interviews (20 participants, 3 intervention providers). Analyses include descriptive statistics, with 95% CI where appropriate; qualitative themes; intervention fidelity from videos and session checklists; rehearsal of health economic analysis.

ETHICS AND DISSEMINATION

National Health Service (NHS) National Research Ethics Service approval granted in April 2015; recruitment started in June. Preliminary studies suggested low risk of serious adverse events; however (minor) falls, transitory muscle soreness and high levels of postexercise fatigue are expected. Outputs include pilot data to inform whether to proceed to a definitive RCT and support a funding application; finalised Trainer and Intervention Delivery manuals for multicentre replication of ReTrain; presentations at conferences, public involvement events; internationally recognised peer-reviewed journal publications, open access sources and media releases.

Development of an active behavioural physiotherapy intervention (ABPI) for acute whiplash-associated disorder (WAD) II management: a modified Delphi study

OBJECTIVE

To develop an active behavioural physiotherapy intervention (ABPI) for managing acute whiplash-associated disorder (WAD) II using a modified Delphi method to develop consensus for the basic features of the ABPI.

DESIGN

Modified Delphi study. Our systematic review and meta-analysis evaluating conservative management for acute WADII found that a combined ABPI may be a useful intervention to prevent patients progressing to chronicity. No previous research has considered a combined behavioural approach and active physiotherapy in the management of acute WADII patients. The ABPI was therefore developed using a rigorous consensus method using international research and local clinical whiplash experts. Descriptive statistics were used to assess consensus in each round.

SETTING

Online international survey.

PARTICIPANTS

A purposive sample of 97 potential participants (aiming to recruit n=30) consisting of international research whiplash experts, UK private physiotherapists and UK postgraduate musculoskeletal physiotherapy students were invited to participate via electronic mail with an attached participant information sheet and consent form.

RESULTS

36 individuals signed and returned the consent form. In round 1, 32/36 participants (response rate=89%, mean age±SD=36.03±13.22 years) across 8 countries (Australia, Finland, Greece, India, Netherlands, Norway, Sweden and UK) contributed to round 1 questionnaire. Response rates were 78% and 75% for rounds 2 and 3, respectively. Following round 3, 12 underlying principles (eg, return to normal function as soon as possible, pain management, encouragement of self-management, reduce fear avoidance and anxiety) achieved consensus. The treatment components reaching consensus included behavioural (eg, education, reassurance, self-management) and physiotherapy components (eg, exercises for stability and mobility). No passive intervention achieved consensus.

CONCLUSIONS

Experts suggested and agreed the underlying principles and treatment components of the ABPI for the management of acute WADII. The ABPI was underpinned by social cognitive theory focusing on self-efficacy enhancement prior to conducting a phase II trial.

The reporting of adverse events following spinal manipulation in randomized clinical trials-a systematic review

BACKGROUND CONTEXT

Spinal manipulative therapy (SMT) is commonly used to treat spinal disorders. Although clinical practice guidelines recommend the use of SMT in the treatment of neck and back disorders, concerns exist about the nature and incidence of adverse events associated with the intervention. Comprehensive reporting of adverse events in clinical trials could allow for accurate incidence estimates through meta-analysis. However, it is not clear if randomized clinical trials (RCTs) that involve SMT are currently reporting adverse events adequately.

PURPOSE

This study aimed to describe the extent of adverse events reporting in published RCTs involving SMT, and to determine whether the quality of reporting has improved since publication of the 2010 Consolidated Standards Of Reporting Trials (CONSORT) statement.

STUDY DESIGN

This is a systematic literature review.

METHODS

The Physiotherapy Evidence Database (PEDro) and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched for RCTs involving SMT. Domains of interest included classifications of adverse events, completeness of adverse events reporting, nomenclature used to describe the events, methodological quality of the study, and details of the publishing journal. Data were analyzed using descriptive statistics. Frequencies and proportions of trials reporting on each of the specified domains above were calculated. Differences in proportions between pre- and post-CONSORT trials were calculated with 95% confidence intervals using standard methods, and statistical comparisons were analyzed using tests for equality of proportions with continuity correction. There was no funding obtained for this study. The authors declare no conflict of interest.

RESULTS

Of 7,398 records identified in the electronic searches, 368 articles were eligible for inclusion in this review. Adverse events were reported in 140 (38.0%) articles. There was a significant increase in the reporting of adverse events post-CONSORT (p=.001). There were two major adverse events reported (0.3%). Only 22 articles (15.7%) reported on adverse events in the abstract. There were no differences in reporting of adverse events post-CONSORT for any of the chosen parameters.

CONCLUSIONS

Although there has been an increase in reporting adverse events since the introduction of the 2010 CONSORT guidelines, the current level should be seen as inadequate and unacceptable. We recommend that authors adhere to the CONSORT statement when reporting adverse events associated with RCTs that involve SMT.

Exploring approaches to patient safety: the case of spinal manipulation therapy

BACKGROUND

The purpose of this study was to gain insight into the current safety culture around the use of spinal manipulation therapy (SMT) by regulated health professionals in Canada and to explore perceptions of readiness for implementing formal mechanisms for tracking associated adverse events.

METHODS

Fifty-six semi-structured telephone interviews were conducted with professional leaders and frontline practitioners in chiropractic, physiotherapy, naturopathy and medicine, all professions regulated to perform SMT in the provinces of Alberta and Ontario Canada. Interviews were digitally audio-recorded for verbatim transcription. Transcripts were entered into HyperResearch software for qualitative data analysis and were coded for both anticipated and emergent themes using the constant comparative method. A thematic, descriptive analysis was produced.

RESULTS

The safety culture around SMT is characterized by substantial disagreement about its actual rather than putative risks. Competing intra- and inter-professional narratives further cloud the safety picture. Participants felt that safety talk is sometimes conflated with competition for business in the context of fee-for-service healthcare delivery by several professions with overlapping scopes of practice. Both professional leaders and frontline practitioners perceived multiple barriers to the implementation of an incident reporting system for SMT.

CONCLUSIONS

The established 'measure and manage' approach to patient safety is difficult to apply to care which is geographically dispersed and delivered by practitioners in multiple professions with overlapping scopes of practice, primarily in a fee-for-service model. Collaboration across professions on models that allow practitioners to share information anonymously and help practitioners learn from the reported incidents is needed.

Medium term effects of including manual therapy in a pulmonary rehabilitation program for chronic obstructive pulmonary disease (COPD): a randomized controlled pilot trial

STUDY DESIGN

Randomized clinical trial.

OBJECTIVE

To investigate the effect of including manual therapy (MT) in a pulmonary rehabilitation program for patients with chronic obstructive pulmonary disease (COPD).

BACKGROUND

The primary source of exercise limitation in people with COPD is dyspnea. The dyspnea is partly caused by changes in chest wall mechanics, with an increase in chest wall rigidity (CWR) contributing to a decrease in lung function. As MT is known to increase joint mobility, administering MT to people with COPD carries with it the potential to influence CWR and lung function.

METHODS

Thirty-three participants with COPD, aged between 55 and 70 years (mean = 65·5±4 years), were randomly assigned to three groups: pulmonary rehabilitation (PR) only, soft tissue therapy (ST) and PR, and ST, spinal manipulative therapy (SM), and PR. Outcome measures including forced expiratory volume in the 1st second (FEV1), forced vital capacity (FVC), 6-minute walking test (6MWT), St. George's respiratory questionnaire (SGRQ), and the hospital anxiety and depression (HAD) scale were recorded at 0, 8, 16, and 24 weeks.

RESULTS

There was a significant difference in FVC between the three groups at 24 weeks (P = 0·04). For the ST+SM+PR group versus PR only the increase was 0·40 l (CI: 0·02, 0·79; P = 0·03). No major or moderate adverse events (AE) were reported following the administration of 131 ST and 272 SM interventions.

DISCUSSION

The increase in FVC is a unique finding. Although the underlying mechanisms responsible for this outcome are not yet understood, the most likely explanation is the synergistic effect resulting from the combination of interventions. These results support the call for a larger clinical trial in the use of MT for COPD.

A critical overview of the current myofascial pain literature - January 2016

Reflecting on the past year, the number of publications on myofascial pain continues to increase in a steady rate. The current review includes 30 basic and clinical studies, case reports, reviews, and reports from fifteen different countries about trigger points (TrP), myofascial pain (MP), dry needling (DN) and other related interventions. We are pleased that during 2015 this article made the top 15 of most downloaded articles as many as three times! In general, the quality of published papers is improving as well. Nevertheless, several papers included in this overview, mention the application of "ischemic compression", which is a questionable concept in the context of TrP inactivation. As we have outlined previously, in the current thinking about myofascial pain, TrPs feature significant hypoxia and a lowered pH (Ballyns et al., 2011; Shah and Gilliams, 2008), and attempts to induce more ischemia would be counterproductive. Already in 1999, Simons, Travell and Simons changed the terminology from ischemic compression to TrP compression (Simons et al., 1999) and we recommend that contemporary researchers and clinicians adopt the new terminology and stop using the term "ischemic compression."

Effectiveness of Soft Tissue Massage for Nonspecific Shoulder Pain: Randomized Controlled Trial

BACKGROUND

Soft tissue massage and exercise are commonly used to treat episodes of shoulder pain.

OBJECTIVE

The study objective was to compare the effects of soft tissue massage and exercise with those of exercise alone on pain, disability, and range of motion in people with nonspecific shoulder pain.

DESIGN

This was a randomized controlled trial.

SETTING

The study was conducted in public hospital physical therapy clinics in Sydney, New South Wales, Australia.

PARTICIPANTS

The study participants were 80 people with an average age of 62.6 years (SD=12.2) who were referred to physical therapists for treatment of nonspecific shoulder pain.

INTERVENTION

Participants were randomly assigned to either a group that received soft tissue massage around the shoulder and exercises (n=40) or a group that received exercise only (n=40) for 4 weeks.

MEASUREMENTS

The primary outcome was improvement in pain, as measured on a 100-mm visual analog scale, 1 week after the cessation of treatment. Secondary outcomes were disability and active flexion, abduction, and hand-behind-back range of motion. Measurements were obtained at baseline, 1 week after the cessation of treatment, and 12 weeks after the cessation of treatment.

RESULTS

The between-group difference in pain scores from the baseline to 12 weeks after the cessation of treatment demonstrated a small significant difference in favor of the group receiving exercise only (mean difference=14.7 mm). There were no significant differences between groups in any other variable.

LIMITATIONS

It was not possible to mask therapists or participants to group allocation. Diagnostic tests were not used on participants to determine specific shoulder pathology.

CONCLUSIONS

The addition of soft tissue massage to an exercise program for the shoulder conferred no additional benefit for improving pain, disability, or range of motion in people with nonspecific shoulder pain.

Safety of thrust joint manipulation in the thoracic spine: a systematic review

BACKGROUND

There appears to be very little in the research literature on the safety of thrust joint manipulation (TJM) when applied to the thoracic spine.

PURPOSE

To retrospectively analyze all available documented case reports in the literature describing patients who had experienced severe adverse events (AE) after receiving TJM to their thoracic spine.

DATA SOURCES

Case reports published in peer reviewed journals were searched in Medline (using Ovid Technologies, Inc.), Science Direct, Web of Science, PEDro (Physiotherapy Evidence Database), Index of Chiropractic literature, AMED (Allied and Alternative Medicine Database), PubMed and the Cumulative Index to Nursing and Allied Health (CINHAL) from January 1950 to February 2015.

STUDY SELECTION

Case reports were included if they: (1) were peer-reviewed; (2) were published between 1950 and 2015; (3) provided case reports or case series; and (4) had TJM as an intervention. Articles were excluded if: (1) the AE occurred without TJM (e.g. spontaneous); (2) the article was a systematic or literature review; or (3) it was written in a language other than English or Spanish.

DATA EXTRACTION

Data extracted from each case report included: gender; age; who performed the TJM and why; presence of contraindications; the number of manipulation interventions performed; initial symptoms experienced after the TJM; as well as type of severe AE that resulted.

RESULTS

Ten cases, reported in 7 case reports, were reviewed. Cases involved females (8) more than males (2), with mean age being 43.5 years (SD=18.73, Range = 17 -71). The most frequent AE reported was injury (mechanical or vascular) to the spinal cord (7/10), with pneumothorax and hematothorax (2/10) and CSF leak secondary to dural sleeve injury (1/10).

LIMITATIONS

There were only a small number of case reports published in the literature and there may have been discrepancies between what was reported and what actually occurred, since physicians dealing with the effects of the AE, rather than the clinician performing the TJM, published the cases.

CONCLUSIONS

Serious AE do occur in the thoracic spine, most commonly, trauma to the spinal cord, followed by pneumothorax. This suggests that excessive peak forces may have been applied to thoracic spine, and it should serve as a cautionary note for clinicians to decrease these peak forces.
