Patient education for neck pain

Therapeutic Patient Education as Part of the Physiotherapy Management of Adults with Headache: A Scoping Review

PURPOSE OF REVIEW

Physiotherapy interventions for headache mostly include exercise and manual therapy. Yet, the complex nature of headache, sometimes characterized by symptoms of facilitated central pain mechanisms, demands an individualized approach in which therapeutic patient education could be supportive. This scoping review aimed to summarize the position of therapeutic patient education within the physiotherapy management of adults with headache. PubMed, EMBASE, Web of Science, and Scopus were searched. The search-query comprised terminology relating to "headache", "education", and "physiotherapy". Eligibility criteria were: adults with headache, interventions including education within the domain of physiotherapy, reviews, clinical trials, cohort, case report, case-control studies.

RECENT FINDINGS

Eleven publications were included from the 281 retrieved publications. These publications were clinical trials (n = 4), reviews (n = 4), case-reports (n = 2), and a guideline (n = 1). Type of headaches studied were migraine (n = 3), post-traumatic headache (n = 2), tension-type headache (n = 2), cervicogenic headache (n = 1), primary headaches (n = 1), chronic daily headache (n = 1), and mixed migraine-cervicogenic headache (n = 1). Education seems an umbrella-term for postural education, lifestyle advice, and pain education. Three themes emerged across the publications: handling headache triggers (migraine, post-traumatic headache), promoting active lifestyle (post-traumatic headache, chronic daily headache, migraine), evaluating posture (post-traumatic headache, chronic daily headache, tension-type headache, cervicogenic headache). All publications recommended education in the management of headache. Only one (of the 11 included) publication described the educational program and determined its efficacy. Based on this scoping review, therapeutic patient education seems supported within physiotherapy management of headache. However, it is unclear how such education is tailored to the specific needs of the individual, the headache subtype, or when it should be added to physiotherapy management of headache.

One and Done? The Effectiveness of a Single Session of Physiotherapy Compared With Multiple Sessions to Reduce Pain and Improve Function and Quality of Life in Patients With a Musculoskeletal Disorder: A Systematic Review With Meta-analyses

OBJECTIVE

To compare single and multiple physiotherapy sessions to improve pain, function, and quality of life (QoL) in patients with musculoskeletal disorders (MSKDs).

DATA SOURCES

AMED, Cinahl, SportsDiscus, Medline, Cochrane Register of Clinical Trials, Physiotherapy Evidence Database, and reference lists.

STUDY SELECTION

Randomized controlled trials (RCTs) comparing single and multiple physiotherapy sessions for MSKDs.

DATA EXTRACTION

Two reviewers extracted data and assessed risk of bias and certainty of evidence using Cochrane Risk of Bias tool 2.0 and Grading of Recommendation Assessment, Development, and Evaluation.

DATA SYNTHESIS

Six RCTs (n=2090) were included (conditions studied: osteoporotic vertebral fracture, neck, knee, and shoulder pain). Meta-analyses with low-certainty evidence showed a significant pain improvement at 6 months in favor of multiple sessions compared with single session interventions (3 RCTs; n=1035; standardized mean difference [SMD]: 0.29; 95% CI: 0.05 to 0.53; P=.02) but this significant difference in pain improvement was not observed at 3 months (4 RCTs; n=1312; SMD: 0.39; 95% CI: -0.11 to 0.89; P=.13) and at 12 months (4 RCTs; n=1266; SMD: -0.05; 95% CI: -0.49 to 0.39; P=.82). Meta-analyses with low-certainty evidence showed no significant differences in function at 3 (4 RCTs; n=1583; SMD: 0.05; 95% CI: -0.11 to 0.21; P=.56), 6 (4 RCTs; n=1538; SMD: 0.06; 95% CI: -0.12 to 0.23; P=.53) and 12 months (4 RCTs; n=1528; SMD: 0.08; 95% CI: -0.08 to 0.25; P=.30) and QoL at 3 (4 RCTs; n=1779; SMD: 0.08; 95% CI: -0.02 to 0.17; P=.12), 6 (3 RCTs; n=1206; SMD: 0.03; 95% CI: -0.08 to 0.14; P=.59), and 12 months (4 RCTs; n=1729; SMD: -0.03; 95% CI: -0.12 to 0.07; P=.58).

CONCLUSIONS

Low certainty meta-analyses found no clinically significant differences in pain, function, and QoL between single and multiple physiotherapy sessions for MSKD management for the conditions studied. Future research should compare the cost-effectiveness of those different models of care.

Effectiveness of Interventions on Work Outcomes After Road Traffic Crash-Related Musculoskeletal Injuries: A Systematic Review and Meta-analysis

BACKGROUND

Musculoskeletal injuries are common after road traffic crash (RTC) and can lead to poor work-related outcomes. This review evaluated the impact of interventions on work-related (e.g. sick leave), health, and functional outcomes in individuals with a RTC-related musculoskeletal injury, and explored what factors were associated with work-related outcomes.

METHODS

Searches of seven databases were conducted up until 9/03/2023. Eligible interventions included adults with RTC-related musculoskeletal injuries, a comparison group, and a work-related outcome, and were in English. Meta-analyses were conducted using RevMan and meta-regressions in Stata.

RESULTS

Studies (n = 27) were predominantly conducted in countries with third-party liability schemes (n = 26), by physiotherapists (n = 17), and in participants with whiplash injuries (94%). Pooled effects in favour of the intervention group were seen overall (SMD = - 0.14, 95% CI: - 0.29, 0.00), for time to return to work (- 17.84 days, 95% CI: - 24.94, - 10.74), likelihood of returning to full duties vs. partial duties (RR = 1.17, 95% CI: 1.01, 1.36), decreased pain intensity (- 6.17 units, 95% CI: - 11.96, - 0.39, 100-point scale), and neck disability (- 1.77 units, 95% CI: - 3.24, - 0.30, 50-point scale).

DISCUSSION

Interventions after RTC can reduce time to return to work and increase the likelihood of returning to normal duties, but the results for these outcomes were based on a small number of studies with low-quality evidence. Further research is needed to evaluate a broader range of interventions, musculoskeletal injury types, and to include better quality work-related outcomes.

Randomised controlled trial assessing the effects of 6-week telerehabilitation exercise programme on chronic non-specific neck pain: a study protocol

Chronic non-specific neck pain is one of the most common musculoskeletal conditions affecting the work and lifestyle of those suffering from it. Physiotherapy interventions, such as strength training and stretching, have positively influenced neck pain. Patient adherence to home-based exercises is a growing concern that could be easily improved through telerehabilitation exercise programmes. This can also be a cost-effective, time-efficient and patient-suitable service. Therefore, this study aims to establish the effectiveness of telerehabilitation exercise intervention by measuring patient adherence, pain score, disability index, cervical range of motion (CROM) and cervical muscle endurance. This randomised controlled trial will include n=60 participants, aged 18-45 years, in a 6-week home-based exercise programme delivered through telerehabilitation or paper-based instructions. Outcome measures from participants will be obtained at baseline and on completion of 6 weeks. These will include the Visual Analogue Scale for Pain, Neck Disability Index questionnaire, CROM by using the CROM instrument and cervical muscle endurance through the Craniocervical Flexion Test. For baseline differences between groups, an independent samples t-test will be used. Repeated measures analysis of variance will be used for within-group and between-group analyses at three different time points (0 weeks, 3 weeks, 6 weeks). Trial registration number:NCT06076174.

Clinical validation of grouping conservative treatments in neck pain for use in a network meta-analysis: a Delphi consensus study

BACKGROUND

A network meta-analysis aims to help clinicians make clinical decisions on the most effective treatment for a certain condition. Neck pain is multifactorial, with various classification systems and treatment options. Classifying patients and grouping interventions in clinically relevant treatment nodes for a NMA is essential, but this process is poorly defined.

OBJECTIVE

Our aim is to obtain consensus among experts on neck pain classifications and the grouping of interventions into nodes for a future network meta-analysis.

DESIGN

A Delphi consensus study involving neck pain experts worldwide.

METHODS

We invited authors of neck pain clinical practice guidelines published from 2014 onwards. The Delphi baseline questionnaire was developed based on the findings of a scoping review, including four items on classifications and 19 nodes. Participants were asked to record their level of agreement on a seven-point Likert scale or using Yes/No/Not sure answer options for the various statements. We used descriptive analysis to summarise the responses on each statement with content analysis of the free-text comments.

RESULTS

In total, 18/80 experts (22.5%) agreed to participate in one or more Delphi rounds. We needed three rounds to reach consensus for two classification of neck pain: one based on aetiology and one on duration. In addition, we also reached consensus on the grouping of interventions, including a definition of each node, with the number of nodes reduced to 17.

CONCLUSION

With this consensus we clinically validated two neck pain classifications and grouped conservative treatments into 17 well-defined and clinically relevant nodes.

Key Learning Statements for persistent pain education: an iterative analysis of consumer, clinician and researcher perspectives and development of public messaging

Over the last decade, the content, delivery and media of pain education have been adjusted in line with scientific discovery in pain and educational sciences, and in line with consumer perspectives. This paper describes a decade-long process of exploring consumer perspectives on pain science education concepts to inform clinician-derived educational updates (undertaken by the authors). Data were collected as part of a quality audit via a series of online surveys in which consent (non-specific) was obtained from consumers for their data to be used in published research. Consumers who presented for care for a persistent pain condition and were treated with a pain science education informed approach were invited to provide anonymous feedback about their current health status and pain journey experience 6, 12 or 18 months after initial assessment. Two-hundred eighteen consumers reported improvement in health status at follow-up. Results of the surveys from three cohorts of consumers that reported improvement were used to generate iterative versions of 'Key Learning Statements'. Early iteration of these Key Learning Statements was used to inform the development of Target Concepts and associated community-targeted pain education resources for use in public health and health professional workforce capacity building initiatives. Perspective This paper reflects an explicit interest in the insights of people who have been challenged by persistent pain and then recovered, to improve pain care. Identifying pain science concepts that consumers valued learning provided valuable information to inform resources for clinical interactions and community-targeted pain education campaigns.

Thread Embedded Acupuncture for Non-Specific Posterior Neck Pain: A PRISMA-Compliant Protocol for Systematic Review and Meta-Analysis

Purpose

The prevalence of non-specific posterior neck pain (NPNP) has been increasing yearly. There are several treatments for NPNP, but in this review, we will focus on thread-embedded acupuncture (TEA). TEA is used in the Republic of Korea, Taiwan, and China for managing musculoskeletal diseases, obesity, and sequelae of facial palsy. However, there is insufficient evidence on its effectiveness and safety. This study aims to assess the efficacy and safety of TEA for NPNP.

Methods

We will search the following nine electronic databases, from their inception to May 2020: MEDLINE, Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Citation Information by the National Information infrastructure, Korean Studies Information Service System, National Digital Science Library, Oriental Medicine Advanced Searching Integrated System, and Research Information Service System. Only randomized controlled trials of TEA for NPNP will be included. The methodological quality of the included trials will be assessed using the Cochrane risk-of bias tool. To conduct the meta-analysis, the risk ratio and mean difference with the 95% confidence interval will be used. Sensitivity analyses will be conducted based on this protocol.

Results

The results of this study will be submitted to a peer-reviewed journal for publication.

Conclusion

The results of this study would provide the evidence of whether TEA can be effective for treating NPNP.

Is Dry Needling Effective When Combined with Other Therapies for Myofascial Trigger Points Associated with Neck Pain Symptoms? A Systematic Review and Meta-Analysis

Objective

To evaluate the effects of combining dry needling with other physical therapy interventions versus the application of the other interventions or dry needling alone applied over trigger points (TrPs) associated to neck pain. Databases and Data Treatment. Electronic databases were searched for randomized controlled trials where at least one group received dry needling combined with other interventions for TrPs associated with neck pain. Outcomes included pain intensity, pain-related disability, pressure pain thresholds, and cervical range of motion. The risk of bias (RoB) was assessed using the Cochrane risk of bias tool, methodological quality was assessed with PEDro score, and the quality of evidence was assessed by using the GRADE approach. Between-groups mean differences (MD) and standardized mean difference (SMD) were calculated.

Results

Eight trials were included. Dry needling combined with other interventions reduced pain intensity at short-term (SMD -1.46, 95% CI -2.25 to -0.67) and midterm (SMD -0.38, 95% CI -0.74 to -0.03) but not immediately after or at long-term compared with the other interventions alone. A small effect on pain-related disability was observed at short-term (SMD -0.45, 95% CI -0.87 to -0.03) but not at midterm or long-term. The inclusion of dry needling was also effective for improving pressure pain thresholds only at short-term (MD 112.02 kPa, 95% CI 27.99 to 196.06). No significant effects on cervical range of motion or pain catastrophism were observed.

Conclusion

Low-to-moderate evidence suggests a positive effect to the combination of dry needling with other interventions for improving pain intensity, pain-related disability, pressure pain thresholds, and cervical range of motion in people with neck pain associated with TrPs at short-term. No midterm or long-term effects were observed.

Combining Patient Education With Dry Needling and Ischemic Compression for Treating Myofascial Trigger Points in Office Workers With Neck Pain: A Single-Blinded, Randomized Trial

Objective

The purpose of this study was to compare immediate and short-term effects of combining dray needling (DN) + patient education vs ischemic compression (IC) + patient education for treating myofascial trigger points (MTP) in office workers with neck pain.

Methods

This was a single-blinded, randomized trial. Thirty-two participants were randomly assigned to either DN + patient education or IC + patient education group. Both groups received 2 treatment sessions with a 48-hour time interval. Pain intensity, cervical range of motion, Neck Disability Index, and satisfaction were measured.

Results

Pain intensity and neck disability level decreased, whereas the cervical range of motion (side-bending and rotation) increased in both groups. Analysis of variance revealed a significant interaction of group × treatment only for pain intensity, indicating a greater reduction in the IC group. Satisfaction generally increased in the follow-up assessment in both groups.

Conclusion

Both intervention groups had some positive immediate and short-term effects after 2 treatment sessions. However, IC + patient education was more effective than DN + patient education in the treatment of MTPs in office workers with neck pain.

Effectiveness of Dry Needling for Myofascial Trigger Points Associated with Neck Pain Symptoms: An Updated Systematic Review and Meta-Analysis

Our aim was to evaluate the effect of dry needling alone as compared to sham needling, no intervention, or other physical interventions applied over trigger points (TrPs) related with neck pain symptoms. Randomized controlled trials including one group receiving dry needling for TrPs associated with neck pain were identified in electronic databases. Outcomes included pain intensity, pain-related disability, pressure pain thresholds, and cervical range of motion. The Cochrane risk of bias tool and the Physiotherapy Evidence Database (PEDro) score were used to assessed risk of bias (RoB) and methodological quality of the trials. The quality of evidence was assessed by using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Between-groups mean differences (MD) and standardized mean differences (SMD) were calculated (3) Twenty-eight trials were finally included. Dry needling reduced pain immediately after (MD -1.53, 95% CI -2.29 to -0.76) and at short-term (MD -2.31, 95% CI -3.64 to -0.99) when compared with sham/placebo/waiting list/other form of dry needling and, also, at short-term (MD -0.51, 95% CI -0.95 to -0.06) compared with manual therapy. No differences in comparison with other physical therapy interventions were observed. An effect on pain-related disability at the short-term was found when comparing dry needing with sham/placebo/waiting list/other form of dry needling (SMD -0.87, 95% CI -1.60 to -0.14) but not with manual therapy or other interventions. Dry needling was effective for improving pressure pain thresholds immediately after the intervention (MD 55.48 kPa, 95% CI 27.03 to 83.93). No effect on cervical range of motion of dry needling against either comparative group was found. No between-treatment effect was observed in any outcome at mid-term. Low to moderate evidence suggests that dry needling can be effective for improving pain intensity and pain-related disability in individuals with neck pain symptoms associated with TrPs at the short-term. No significant effects on pressure pain sensitivity or cervical range of motion were observed. Registration number: OSF Registry-https://doi.org/10.17605/OSF.IO/P2UWD.

Preoperative pain neuroscience education for shoulder surgery: A case series

Background

Central sensitisation, in addition to high levels of fear-avoidance and pain catastrophisation may exist in a subgroup of patients with shoulder pain. Pain neuroscience education (PNE) has been shown to positively influence sensitivity of the nervous system, as well as reduce fear and catastrophisation prior to lumbar and total knee surgery. To date, no study has examined the application of PNE prior to shoulder surgery.

Objectives

This study examined the response to preoperative PNE in patients preparing for shoulder surgery.

Method

An exploratory pre–post case series was conducted. Twelve patients scheduled for surgery completed various pre-education measurements including shoulder pain, fear-avoidance, pain catastrophisation, beliefs and expectations regarding surgery, active shoulder flexion and pressure pain thresholds for the involved and uninvolved shoulder and the dominant-sided knee. Patients underwent a standard 30-min, one-on-one PNE session with a physiotherapist prior to surgery.

Results

Following education, all measures improved with some failing to reach significance: self-reported pain (p = 0.125), pain catastrophisation (p = 0.250) and pain pressure threshold of the uninvolved shoulder (p = 0.68) and knee (p = 0.097). Fear-avoidance (p = 0.013), active shoulder flexion (p = 0.013) and pain pressure threshold for the involved shoulder (p = 0.004) significantly improved.

Conclusion

A small patient group improved beyond minimal detectable change and/or minimal clinical important difference after education. No significant shifts of the preoperative beliefs occurred after education.

Clinical implications

Preoperative PNE may be beneficial to a subgroup of patients scheduled for shoulder surgery.

Integration of Conversion Factors for the Development of an Inclusive eHealth Tool With Caregivers of Functionally Dependent Older Persons: Social Justice Design

BACKGROUND

eHealth can help reduce social health inequalities (SHIs); at the same time, it also has the potential to increase them. Several conversion factors can be integrated into the development of an eHealth tool to make it inclusive: (1) providing physical, technical, and financial access to eHealth; (2) enabling the integration of people at risk of SHIs into the research and development of digital projects targeting such populations (co-design or participatory research); (3) promoting consistency between the digital health literacy level of future users (FUs) and the eHealth tool; (4) developing an eHealth tool that is consistent with the technological skills of FUs; (5) ensuring that the eHealth tool is consistent with the help-seeking process of FUs; (6) respecting the learning capacities of FUs; and (7) being sensitive to FUs' cultural context. However, only little empirical evidence pointing out how these conversion factors can be integrated into an effective eHealth tool is available.

OBJECTIVE

On the basis of Amartya Sen's theoretical framework of social justice, the objective of this study was to explore how these 7 conversion factors can be integrated into an eHealth tool for caregivers of functionally dependent older persons.

METHODS

This study was based on a social justice design and participant observation as part of a large-scale research project funded by the Ministère de la Famille through the Quebec Ami des Aînés Program. Data were collected by recording the preparation sessions, the co-design and advisory committee sessions, as well as the debriefing sessions. The results were analyzed using Miles and Huberman's method.

RESULTS

A total of 78 co-designers participated in 11 co-design sessions, 24 preparation sessions, and 11 debriefing sessions. Of the 7 conversion factors, 5 could be explored in this experiment. The integration of conversion factors has been uneven. The participation of FUs in the development of the tool supports other conversion factors. Respecting the eHealth literacy level of FUs means that their learning abilities and technological skills are also respected because they are closely related to one another and are therefore practically difficult to be distinguished.

CONCLUSIONS

Conversion factors can be integrated into the development of eHealth tools that are intended to be inclusive and contribute to curbing SHIs by integrating FU participation into the tool design process.

Intervention with an educational video after a whiplash trauma - a randomised controlled clinical trial

Background and aims Previous systematic reviews have considered that providing patient information is ineffective for patients with whiplash-associated disorders (WAD), with the exception of interventional educational videos. The aim of this randomised controlled clinical trial was to determine if use of an educational video as an intervention in the acute stage after a whiplash injury might improve self-reported recovery at 6 months after the injury. Methods In total, 289 consecutive patients with a whiplash injury following a motor vehicle collision were randomised to an intervention group (educational video) or to a control group (written information sheet). The video focused on information about pain mechanisms, deep flexor physiotherapy and reassurance. Emailed questionnaires were used to collect baseline data within 2 weeks after the accident and then to collect outcome data at 6 months post-injury. Non-responders were followed up with a brief telephone interview regarding the outcome. The primary outcome measure was self-reported recovery (yes/no) at 6 months post-injury. The secondary outcomes measures were pain level according to a numeric rating scale (NRS) and the whiplash disability questionnaire (WDQ) score at the same time point. Results The response rate for the baseline questionnaire was 70% (203/289). The follow-up rate was 97% (196/203). The non-recovery rates were similar between the intervention group, at 37.9% (39/103), and the control group, at 33.3% (31/93) (p = 0.55). No differences between the groups were noted in pain levels, NRS scores (1.9 vs. 2.2, p = 0.35) or the mean WDQ scores (17.5 vs. 21.2, p = 0.42). Conclusions The intervention with the educational video used in this study had no effect on the non-recovery rate when compared to a basic written information sheet. Implications The results of this trial add knowledge to the area of patient education for patients with acute WAD. Further studies are needed before the current recommendations for patient information are modified.

Predicting the evolution of neck pain episodes in routine clinical practice

BACKGROUND

The objective of this study was to develop models for predicting the evolution of a neck pain (NP) episode.

METHODS

Three thousand two hundred twenty-five acute and chronic patients seeking care for NP, were recruited consecutively in 47 health care centers. Data on 37 variables were gathered, including gender, age, employment status, duration of pain, intensity of NP and pain referred down to the arm (AP), disability, history of neck surgery, diagnostic procedures undertaken, imaging findings, clinical diagnosis, and treatments used. Three separate multivariable logistic regression models were developed for predicting a clinically relevant improvement in NP, AP and disability at 3 months.

RESULTS

Three thousand one (93.5%%) patients attended follow-up. For all the models calibration was good. The area under the ROC curve was ≥0.717 for pain and 0.664 for disability. Factors associated with a better prognosis were: a) For all the outcomes: pain being acute (vs. chronic) and having received neuro-reflexotherapy. b) For NP: nonspecific pain (vs. pain caused by disc herniation or spinal stenosis), no signs of disc degeneration on imaging, staying at work, and being female. c) For AP: nonspecific NP and no signs of disc degeneration on imaging. d) For disability: staying at work and no signs of facet joint degeneration on imaging.

CONCLUSIONS

A prospective registry can be used for developing valid predictive models to quantify the odds that a given patient with NP will experience a clinically relevant improvement.

Effectiveness of a "Spring Pillow" Versus Education in Chronic Nonspecific Neck Pain: A Randomized Controlled Trial

BACKGROUND

Different types of pillows have been proposed for neck pain, but no previous randomized controlled trial has investigated the effectiveness of a "spring pillow" for adults with chronic nonspecific neck pain.

OBJECTIVE

We evaluated the effectiveness of using a pillow made from viscoelastic polyurethane and 60 independent springs compared with an educational intervention in individuals with chronic nonspecific neck pain.

DESIGN

This was a randomized controlled trial with crossover study design.

SETTING

The setting was the Occupational Medicine Unit, University Hospital, Bologna (Italy).

PARTICIPANTS

We recruited 70 adults with chronic nonspecific neck pain, of whom 64 completed the trial.

INTERVENTION

Participants were randomly assigned to 2 groups. One group used the spring pillow for 4 weeks, and the other group followed educational advice for 4 weeks while continuing to use their own pillows. After 4 weeks of treatment and 4 weeks of washout, groups were crossed over. Pain perceived in the neck, thoracic, and shoulder areas and headache were the primary outcome measures. In addition, disability, sleep quality, subjective improvement, and pillow comfort were assessed. Measures were captured at pretreatment, after 4 weeks, after the 4-week washout period, and 4 weeks after crossover. The mean differences (MD) in outcomes between groups were assessed.

RESULTS

Treatment with the spring pillow appeared to reduce neck pain (MD = -8.7; 95% confidence interval [CI] = -14.7 to -2.6), thoracic pain (MD = -8.4; 95% CI = -15.2 to -1.5), and headache (MD = -16.0; 95% CI = -23.2 to -8.7). Reductions in shoulder pain were not statistically significant between groups (MD = -6.9; 95% CI = -14.1-0.3). Neither the crossover sequence nor the period (first vs second intervention administration) significantly affected the results.

LIMITATIONS

Education may not have been the best comparator for the spring pillow; drug consumption, actual pillow use, and the implementation of the educational suggestions as prescribed were not controlled.

CONCLUSIONS

Use of the spring pillow in this study was more effective than an educational intervention for improving cervical, thoracic, and head pain. Whether a spring pillow is more effective than other ergonomic pillows remains to be tested.

Best Evidence Rehabilitation for Chronic Pain Part 4: Neck Pain

Neck pain, whether from a traumatic event such as a motor vehicle crash or of a non-traumatic nature, is a leading cause of worldwide disability. This narrative review evaluated the evidence from systematic reviews, recent randomised controlled trials, clinical practice guidelines, and other relevant studies for the effects of rehabilitation approaches for chronic neck pain. Rehabilitation was defined as the aim to restore a person to health or normal life through training and therapy and as such, passive interventions applied in isolation were not considered. The results of this review found that the strongest treatment effects to date are those associated with exercise. Strengthening exercises of the neck and upper quadrant have a moderate effect on neck pain in the short-term. The evidence was of moderate quality at best, indicating that future research will likely change these conclusions. Lower quality evidence and smaller effects were found for other exercise approaches. Other treatments, including education/advice and psychological treatment, showed only very small to small effects, based on low to moderate quality evidence. The review also provided suggestions for promising future directions for clinical practice and research.

Modulation in Elastic Properties of Upper Trapezius with Varying Neck Angle

Background

Neck and shoulder complaints caused by poor posture may influence upper trapezius stiffness. The relationship between the shear elastic modulus of the upper trapezius and cervical flexion angles is unknown. Therefore, it is essential to assess upper trapezius stiffness during cervical flexion. The objectives of this study were to (1) determine the intra- and interoperator reliabilities of evaluating upper trapezius stiffness and calculate the minimal detectable change (MDC); (2) examine the elastic modulus alterations of the upper trapezius during cervical flexion; and (3) explore the difference of upper trapezius stiffness between the dominant and nondominant sides.

Methods

Twenty healthy male participants were recruited in this study. The shear modulus of the upper trapezius was evaluated by two independent investigators using shear wave elastography (SWE) during cervical flexion at 0° and 50°.

Findings

The intraoperator (intraclass correlation coefficient (ICC) = 0.85–0.86) and interoperator (ICC = 0.94–0.98) reliabilities for measuring the shear elastic modulus of the upper trapezius during the cervical flexion ranged from good to excellent. An increase of 35.58% in upper trapezius stiffness was found at 0° to 50° of cervical flexion, and the MDC was 7.04 kPa. In addition, a significant difference was obtained in the elastic modulus of the upper trapezius muscle between the dominant and nondominant sides (P < 0.05).

Conclusions

Our findings revealed that SWE could quantify the elastic modulus of the upper trapezius and monitor its changes. Therefore, further studies are required to delineate the modulation in upper trapezius muscle stiffness among subjects with neck and shoulder pain.

Short-term effect of a chronic pain self-management intervention delivered by an easily accessible primary healthcare service: a randomised controlled trial

OBJECTIVES

To investigate the effects on persons with chronic pain after 3 months of a group-based chronic pain self-management course compared with a drop-in, low-impact outdoor physical group activity on patient activation and a range of secondary outcomes.

DESIGN

An open, pragmatic, parallel group randomised controlled trial. Analyses were performed using a two-level linear mixed model.

SETTING

An easily accessible healthcare service provided by Norwegian public primary healthcare.

PARTICIPANTS

A total of 121 participants with self-reported chronic pain for 3 months or more were randomised with 60 participants placed in the intervention group and 61 placed in the control group (mean age 53 years, 88% women, 63% pain for 10 years or more).

INTERVENTIONS

The intervention group was offered a group-based chronic pain self-management course with 2.5-hour weekly sessions for a period of 6 weeks. The sessions consisted of education, movement exercises and emphasised group discussions. The control group was offered a low-impact outdoor group physical activity in 1-hour weekly sessions that consisted of walking and simple strength exercises for a period of 6 weeks.

MAIN OUTCOMES

The primary outcome was patient activation assessed using the Patient Activation Measure. Secondary outcomes measured included assessments of pain, anxiety and depression, pain self-efficacy, sense of coherence, health-related quality of life, well-being and the 30 s chair to stand test.

RESULTS

There was no effect after 3 months of the group-based chronic pain self-management course compared with the control group for the primary outcome, patient activation (estimated mean difference: -0.5, 95% CI -4.8 to 3.7, p=0.802).

CONCLUSIONS

There was no support for the self-management course having a better effect after 3 months than a low-impact outdoor physical activity offered the control group.

Has the quality of physiotherapy care in patients with Whiplash-associated disorders (WAD) improved over time? A retrospective study using routinely collected data and quality indicators

PURPOSE

To develop valid quality indicators (QIs) for physiotherapy care based on best available evidence, and to use these QIs to explore trends in the quality of physiotherapy care of patients with Whiplash-associated disorders (WAD) using guideline-based routinely collected data (RCD) gathered between 1996 and 2011.

MATERIALS AND METHODS

The study consisted of two phases: 1) development of QIs and 2) analysis of patient records. A set of QIs was developed based on recommendations in the scientific literature and the Dutch Clinical Practice Guideline (CPG) "Physiotherapy Management and WAD". QIs were expressed as percentages, allowing target performance levels to be defined (≥80% or ≤30% depending on whether desired performance required a high or low score on a QI). We then analyzed WAD patient data (N = 810) collected over a period of 16 years in two physiotherapy practices, separating patients into two groups defined as before (Group A 1996-2002; n = 353) and after (Group B 2003-2011; n = 457) implementation and transition to the Dutch CPG "Physiotherapy Management and WAD".

RESULTS

Using an iterative process and input from both experts and users, 28 QIs were developed and subsequently classified per step of the clinical reasoning process for physiotherapy care. Based on 16 years of RCD, we found that the clinical reasoning process differed significantly (P ≤ 0.05) between the groups, in favor of Group B. Twelve of the 25 indicators (48.0%) in Group A and 19 of 26 indicators (73.1%) in Group B met predetermined performance targets. The number of target indicators also differed significantly between groups, favoring Group B (P ≤ 0.05).

CONCLUSION

A preliminary set of novel QIs was developed. Using RCD and these QIs, we conclude that physiotherapy care in our study setting improved over the period 1996-2011. Furthermore, the QIs met the performance targets set for the clinical reasoning process after the transition to the Dutch CPG "Physiotherapy Management and WAD".

Physical activity and exercise for chronic pain in adults: an overview of Cochrane Reviews

BACKGROUND

Chronic pain is defined as pain lasting beyond normal tissue healing time, generally taken to be 12 weeks. It contributes to disability, anxiety, depression, sleep disturbances, poor quality of life, and healthcare costs. Chronic pain has a weighted mean prevalence in adults of 20%.For many years, the treatment choice for chronic pain included recommendations for rest and inactivity. However, exercise may have specific benefits in reducing the severity of chronic pain, as well as more general benefits associated with improved overall physical and mental health, and physical functioning.Physical activity and exercise programmes are increasingly being promoted and offered in various healthcare systems, and for a variety of chronic pain conditions. It is therefore important at this stage to establish the efficacy and safety of these programmes, and furthermore to address the critical factors that determine their success or failure.

OBJECTIVES

To provide an overview of Cochrane Reviews of adults with chronic pain to determine (1) the effectiveness of different physical activity and exercise interventions in reducing pain severity and its impact on function, quality of life, and healthcare use; and (2) the evidence for any adverse effects or harm associated with physical activity and exercise interventions.

METHODS

We searched theCochrane Database of Systematic Reviews (CDSR) on the Cochrane Library (CDSR 2016, Issue 1) for systematic reviews of randomised controlled trials (RCTs), after which we tracked any included reviews for updates, and tracked protocols in case of full review publication until an arbitrary cut-off date of 21 March 2016 (CDSR 2016, Issue 3). We assessed the methodological quality of the reviews using the AMSTAR tool, and also planned to analyse data for each painful condition based on quality of the evidence.We extracted data for (1) self-reported pain severity, (2) physical function (objectively or subjectively measured), (3) psychological function, (4) quality of life, (5) adherence to the prescribed intervention, (6) healthcare use/attendance, (7) adverse events, and (8) death.Due to the limited data available, we were unable to directly compare and analyse interventions, and have instead reported the evidence qualitatively.

MAIN RESULTS

We included 21 reviews with 381 included studies and 37,143 participants. Of these, 264 studies (19,642 participants) examined exercise versus no exercise/minimal intervention in adults with chronic pain and were used in the qualitative analysis.Pain conditions included rheumatoid arthritis, osteoarthritis, fibromyalgia, low back pain, intermittent claudication, dysmenorrhoea, mechanical neck disorder, spinal cord injury, postpolio syndrome, and patellofemoral pain. None of the reviews assessed 'chronic pain' or 'chronic widespread pain' as a general term or specific condition. Interventions included aerobic, strength, flexibility, range of motion, and core or balance training programmes, as well as yoga, Pilates, and tai chi.Reviews were well performed and reported (based on AMSTAR), and included studies had acceptable risk of bias (with inadequate reporting of attrition and reporting biases). However the quality of evidence was low due to participant numbers (most included studies had fewer than 50 participants in total), length of intervention and follow-up (rarely assessed beyond three to six months). We pooled the results from relevant reviews where appropriate, though results should be interpreted with caution due to the low quality evidence. Pain severity: several reviews noted favourable results from exercise: only three reviews that reported pain severity found no statistically significant changes in usual or mean pain from any intervention. However, results were inconsistent across interventions and follow-up, as exercise did not consistently bring about a change (positive or negative) in self-reported pain scores at any single point. Physical function: was the most commonly reported outcome measure. Physical function was significantly improved as a result of the intervention in 14 reviews, though even these statistically significant results had only small-to-moderate effect sizes (only one review reported large effect sizes). Psychological function and quality of life: had variable results: results were either favourable to exercise (generally small and moderate effect size, with two reviews reporting significant, large effect sizes for quality of life), or showed no difference between groups. There were no negative effects. Adherence to the prescribed intervention: could not be assessed in any review. However, risk of withdrawal/dropout was slightly higher in the exercising group (82.8/1000 participants versus 81/1000 participants), though the group difference was non-significant. Healthcare use/attendance: was not reported in any review. Adverse events, potential harm, and death: only 25% of included studies (across 18 reviews) actively reported adverse events. Based on the available evidence, most adverse events were increased soreness or muscle pain, which reportedly subsided after a few weeks of the intervention. Only one review reported death separately to other adverse events: the intervention was protective against death (based on the available evidence), though did not reach statistical significance.

AUTHORS' CONCLUSIONS

The quality of the evidence examining physical activity and exercise for chronic pain is low. This is largely due to small sample sizes and potentially underpowered studies. A number of studies had adequately long interventions, but planned follow-up was limited to less than one year in all but six reviews.There were some favourable effects in reduction in pain severity and improved physical function, though these were mostly of small-to-moderate effect, and were not consistent across the reviews. There were variable effects for psychological function and quality of life.The available evidence suggests physical activity and exercise is an intervention with few adverse events that may improve pain severity and physical function, and consequent quality of life. However, further research is required and should focus on increasing participant numbers, including participants with a broader spectrum of pain severity, and lengthening both the intervention itself, and the follow-up period.

A concise rehabilitation protocol for sub-acute and chronic non-specific neck pain

There is increasing evidence in support of multidisciplinary approaches for management of chronic neck pain. Although presence of different team members is one of the strengths of these approaches, it can limit the access to these treatments. The main objective of this study is designing and investigating the efficacy of a concise rehabilitation program. Thirty-nine patients with sub-acute and chronic non-specific neck pain underwent an 8-week rehabilitation program. Baseline and 8 weeks' follow-up data regarding neck pain (visual analog scale, neck disability index and quality of life) were compared using paired T test. After eight weeks of study, pain and disability significantly decreased: -3.8 of 10 (95% CI: -4.6 to -3.0) (p-value < 0.001) for pain and -18.4 of 100 (95% CI: -23.7 to -13.2) (p-value < 0.001) for disability. Also, all SF-36 domain scales improved significantly. By using this concise rehabilitation approach, pain, disability, and quality of life improved significantly in patients with sub-acute and chronic non-specific neck pain.

Characterizing patient-oriented tools that could be packaged with guidelines to promote self-management and guideline adoption: a meta-review

BACKGROUND

Self-management is an important component of care for patients or consumers (henceforth termed patients) with chronic conditions. Research shows that patients view guidelines as potential sources of self-management support. However, few guidelines provide such support. The primary purpose of this study was to characterize effective types of self-management interventions that could be packaged as resources in (i.e., appendices) or with guidelines (i.e., accompanying products).

METHODS

We conducted a meta-review of systematic reviews that evaluated self-management interventions. MEDLINE, EMBASE, and the Cochrane Library were searched from 2005 to 2014 for English language systematic reviews. Data were extracted on study characteristics, intervention (content, delivery, duration, personnel, single or multifaceted), and outcomes. Interventions were characterized by the type of component for different domains (inform, activate, collaborate). Summary statistics were used to report the characteristics, frequency, and impact of the types of self-management components. A Measurement Tool to Assess Systematic Reviews (AMSTAR) was used to assess the methodological quality of included reviews.

RESULTS

Seventy-seven studies were included (14 low, 44 moderate, 18 high risk of bias). Reviews addressed numerous clinical topics, most frequently diabetes (23, 30 %). Fifty-four focused on single (38 educational, 16 self-directed) and 21 on multifaceted interventions. Support for collaboration with providers was the least frequently used form of self-management. Most conditions featured multiple types of self-management components. The most frequently occurring type of self-management component across all studies was lifestyle advice (72 %), followed by psychological strategies (69 %), and information about the condition (49 %). In most reviews, the intervention both informed and activated patients (57, 76 %). Among the reviews that achieved positive results, 83 % of interventions involved activation alone, 94 % in combination with information, and 95 % in combination with information and collaboration. No trends in the characteristics and impact of self-management by condition were observed.

CONCLUSIONS

This study revealed numerous opportunities for enhancing guidelines with resources for both patients and providers to support self-management. This includes single resources that provide information and/or prompt activation. Further research is needed to more firmly establish the statistical association between the characteristics of self-management support and outcomes; and to and optimize the design of self-management resources that are included in or with guidelines, in particular, resources that prompt collaboration with providers.

Effects of education to facilitate knowledge about chronic pain for adults: a systematic review with meta-analysis

BACKGROUND

Chronic pain can contribute to disability, depression, anxiety, sleep disturbances, poor quality of life and increased health care costs, with close to 20 % of the adult population in Europe reporting chronic pain. To empower the person to self-manage, it is advocated that education and training about the nature of pain and its effects and how to live with pain is provided. The objective of this review is to determine the level of evidence for education to facilitate knowledge about chronic pain, delivered as a stand-alone intervention for adults, to reduce pain and disability.

METHODS

We identified randomised controlled trials of educational intervention for chronic pain by searching CENTRAL, MEDLINE, EMBASE and ongoing trials registries (inception to December 2013). Main inclusion criteria were (1) pain >3 months; (2) study design that allowed isolation of effects of education and (3) measures of pain or disability. Two reviewers independently screened and appraised each study.

RESULTS

Nine studies were analysed. Pooled data from five studies, where the comparator group was usual care, showed no improvement in pain or disability. In the other four studies, comparing different types of education, there was no evidence for an improvement in pain; although, there was evidence (from one study) of a decrease in disability with a particular form of education-pain neurophysiology education (PNE). Post-hoc analysis of psychosocial outcomes reported in the studies showed evidence of a reduction in catastrophising and an increase of knowledge about pain following PNE.

CONCLUSIONS

The evidence base is limited by the small numbers of studies, their relatively small sample sizes, and the diversity in types of education studied. From that limited evidence, the only support for this type of education is for PNE, though it is insufficiently strong to recommend conclusively that PNE should be delivered as a stand-alone intervention. It therefore remains sensible to recommend that education be delivered in conjunction with other pain management approaches as we cannot confidently conclude that education alone is effective in reducing pain intensity or related disability in chronic pain in adults.

Reducing Care Utilisation through Self-management Interventions (RECURSIVE): a systematic review and meta-analysis

Background

A critical part of future service delivery will involve improving the degree to which people become engaged in ‘self-management’. Providing better support for self-management has the potential to make a significant contribution to NHS efficiency, as well as providing benefits in patient health and quality of care.

Objective

To determine which models of self-management support are associated with significant reductions in health services utilisation (including hospital use) without compromising outcomes, among patients with long-term conditions.

Data sources

Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health, EconLit (the American Economic Association’s electronic bibliography), EMBASE, Health Economics Evaluations Database, MEDLINE (the US National Library of Medicine’s database), MEDLINE In-Process & Other Non-Indexed Citations, NHS Economic Evaluation Database (NHS EED) and PsycINFO (the behavioural science and mental health database), as well as the reference lists of published reviews of self-management support.

Methods

We included patients with long-term conditions in all health-care settings and self-management support interventions with varying levels of additional professional support and input from multidisciplinary teams. Main outcome measures were quantitative measures of service utilisation (including hospital use) and quality of life (QoL). We presented the results for each condition group using a permutation plot, plotting the effect of interventions on utilisation and outcomes simultaneously and placing them in quadrants of the cost-effectiveness plane depending on the pattern of outcomes. We also conducted conventional meta-analyses of outcomes.

Results

We found 184 studies that met the inclusion criteria and provided data for analysis. The most common categories of long-term conditions included in the studies were cardiovascular (29%), respiratory (24%) and mental health (16%). Of the interventions, 5% were categorised as ‘pure self-management’ (without additional professional support), 20% as ‘supported self-management’ (< 2 hours’ support), 47% as ‘intensive self-management’ (> 2 hours’ support) and 28% as ‘case management’ (> 2 hours’ support including input from a multidisciplinary team). We analysed data across categories of long-term conditions and also analysed comparing self-management support (pure, supported, intense) with case management. Only a minority of self-management support studies reported reductions in health-care utilisation in association with decrements in health. Self-management support was associated with small but significant improvements in QoL. Evidence for significant reductions in utilisation following self-management support interventions were strongest for interventions in respiratory and cardiovascular disorders. Caution should be exercised in the interpretation of the results, as we found evidence that studies at higher risk of bias were more likely to report benefits on some outcomes. Data on hospital use outcomes were also consistent with the possibility of small-study bias.

Limitations

Self-management support is a complex area in which to undertake literature searches. Our analyses were limited by poor reporting of outcomes in the included studies, especially concerning health-care utilisation and costs.

Conclusions

Very few self-management support interventions achieve reductions in utilisation while compromising patient outcomes. Evidence for significant reductions in utilisation were strongest for respiratory disorders and cardiac disorders. Research priorities relate to better reporting of the content of self-management support, exploration of the impact of multimorbidity and assessment of factors influencing the wider implementation of self-management support.

Effectiveness of a cognitive-behavioural group intervention for knee osteoarthritis pain: a randomized controlled trial

OBJECTIVE

To assess the effectiveness of a six week cognitive-behavioural group intervention in patients with knee osteoarthritis pain.

DESIGN

Single-blinded randomized controlled trial.

STUDY SETTING

Primary care providers in a medium-sized city in Finland.

PATIENTS

A total of 111 participants aged from 35 to 75 with clinical symptoms and radiographic grading (Kellgren-Lawrence 2-4) of knee osteoarthritis were included.

INTERVENTIONS

In the intervention group, 55 participants attended a cognitive-behavioural training programme for pain management with six weekly group sessions supervised by a psychologist and a physiotherapist. Concurrently, they and the 56 participants of the control group continued in ordinary GP care that was not altered by the study.

MAIN MEASURES

The primary outcome on three-month and 12-month follow-up was the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis index pain subscale. Secondary outcome measures included self-reports of pain and physical function, health-related quality of life, and a comprehensive set of psychological questionnaires.

RESULTS

Mixed model results showed no significant differences between the intervention and control group for any measures of pain or function. A significant difference between the groups was found in the Pain Self-Efficacy Questionnaire (Pr = 0.022) in favour of the control group, and in the RAND-36 emotional well-being subscale in favour of the intervention group (Pr = 0.038). Conventional group comparisons of mean follow-up values showed no significant differences in any of the outcome variables.

CONCLUSION

This trial could not confirm the hypothesized advantage of a cognitive-behavioural training programme over ordinary GP care in knee osteoarthritis pain patients.

Bee venom acupuncture, NSAIDs or combined treatment for chronic neck pain: study protocol for a randomized, assessor-blind trial

BACKGROUND

Chronic neck pain (CNP) is a common painful medical condition with a significant socioeconomic impact. In spite of widespread usage, the effectiveness and safety of combined treatments between conventional and complementary alternative medical treatment modalities has not been fully established in a rigorous randomized clinical trial (RCT). This pilot study will provide the clinical evidence to evaluate the feasibility and refine the protocol for a full-scale RCT on combined treatment of bee venom acupuncture (BVA) and non-steroidal anti-inflammatory drugs (NSAIDs) in patients with CNP.

METHODS/DESIGN

This is a randomized, single-blind clinical trial with three parallel arms. Sixty patients between 18 and 65 years of age with non-specific, uncomplicated neck pain lasting for at least three months will be enrolled. Participants will be randomly allocated into the BVA, NSAIDs or combined treatment group. Assessors and statisticians will be blinded to the random allocation. All researchers will receive training to ensure their strict adherence to the study protocol. Patients from the BVA and combined treatment group will be treated with a bee venom increment protocol into predefined acupoints for six sessions over a three week period. BVA intervention is developed through a comprehensive discussion among interdisciplinary spine disorder experts, according to the guidelines of Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA). Patients from the NSAIDs and combined treatment groups will be prescribed loxoprofen (one tablet to be taken orally, three times a day for three weeks). Bothersomeness from CNP measured using a visual analogue scale (VAS) will be the primary outcome assessed at screening, visit two (baseline), four, six, eight (4th week assessment) and nine (8th week assessment) follow-up session. VAS for pain intensity, neck disability index (NDI), quality of life, depressive status and adverse experiences will also be analyzed.

DISCUSSION

Our study results will contribute to feasibility evaluation and to relevant RCT protocol development for a full-scale RCT on combined treatment of BVA and NSAIDs for CNP patients.

Multidimensional associative factors for improvement in pain, function, and working capacity after rehabilitation of whiplash associated disorder: a prognostic, prospective outcome study

BACKGROUND

Whiplash associated disorders (WAD) have dramatic consequences for individual and public health. Risk factors for better and worse outcomes are important to optimize management. This study aimed to determine short- and mid-term associative co-factors of neck pain relief, improved physical functioning, and improved working capacity (dependent variables) in patients suffering from whiplash associated disorder who participated in a standardized, inpatient pain management program.

METHODS

Naturalistic, observational, prospective cohort study. Outcome was measured by standardized assessment instruments. Co-factors covered sociodemographics, comorbidities, social participation, affective health, and coping abilities. Stepwise, multivariate linear regression analysis was performed at discharge and at the 6-month follow-up.

RESULTS

All regression models explained high proportions of variance (53.3% - 72.1%). The corresponding baseline level was significantly associated with a change in every dependent variable (explained variances: 11.4%-56.7%). Pain relief significantly depended on improved function and vice-versa (3.4%-14.8%). Improved ability to decrease pain was associated with pain relief at discharge (9.6%). Functional improvement was associated with decreased catastrophizing (19.4%) at discharge and decreased depression (20.5%) at the 6 month follow-up.

CONCLUSIONS

Pain relief, improved physical function and working capacity were associated with each other. Improved coping (catastrophizing and ability to decrease pain) and reduced depression may act as important predictors for pain relief and improved function. These findings offer toe-holds for optimized therapy of chronic WAD.

Psychological Care, Patient Education, Orthotics, Ergonomics and Prevention Strategies for Neck Pain: An Systematic Overview Update as Part of the ICON Project

OBJECTIVES

To conduct an overview on psychological interventions, orthoses, patient education, ergonomics, and 1⁰/2⁰ neck pain prevention for adults with acute-chronic neck pain.

SEARCH STRATEGY

Computerized databases and grey literature were searched (2006-2012).

SELECTION CRITERIA

Systematic reviews of randomized controlled trials (RCTs) on pain, function/disability, global perceived effect, quality-of-life and patient satisfaction were retrieved.

DATA COLLECTION & ANALYSIS

Two independent authors selected articles, assessed risk of bias using AMSTAR tool and extracted data. The GRADE tool was used to evaluate the body of evidence and an external panel to provide critical review.

MAIN RESULTS

We retrieved 30 reviews (5-9 AMSTAR score) reporting on 75 RCTs with the following moderate GRADE evidence. For acute whiplash associated disorder (WAD), an education video in emergency rooms (1RCT, 405participants] favoured pain reduction at long-term follow-up thus helping 1 in 23 people [Standard Mean Difference: -0.44(95%CI: -0.66 to -0.23)). Use of a soft collar (2RCTs, 1278participants) was not beneficial in the long-term. For chronic neck pain, a mind-body intervention (2RCTs, 1 meta-analysis, 191participants) improved short-term pain/function in 1 of 4 or 6 participants. In workers, 2-minutes of daily scapula-thoracic endurance training (1RCT, 127participants) over 10 weeks was beneficial in 1 of 4 participants. A number of psychosocial interventions, workplace interventions, collar use and self-management educational strategies were not beneficial.

REVIEWERS' CONCLUSIONS

Moderate evidence exists for quantifying beneficial and non-beneficial effects of a limited number of interventions for acute WAD and chronic neck pain. Larger trials with more rigorous controls need to target promising interventions.

Evidence of Physiotherapy Interventions for Patients with Chronic Neck Pain: A Systematic Review of Randomised Controlled Trials

Chronic neck pain (CNP) is common and costly, and the effect of physiotherapeutic interventions on the condition is unclear. We reviewed the literature for evidence of effect of physiotherapy interventions on patients with CNP. Five bibliographic databases (MEDLINE, EMBASE, CINAHL, Cochrane Library, and PEDro) were systematically searched. Randomised, placebo and active-treatment-controlled trials including physiotherapy interventions for adults with CNP were selected. Data were extracted primary outcome was pain. Risk of bias was appraised. Effect of an intervention was assessed, weighted to risk of bias. 42 trials reporting on randomised comparisons of various physiotherapy interventions and control conditions were eligible for inclusion involving 3919 patients with CNP. Out of these, 23 were unclear or at high risk of bias, and their results were considered moderate- or low-quality evidence. Nineteen were at low risk of bias, and here eight trials found effect on pain of a physiotherapy intervention. Only exercise therapy, focusing on strength and endurance training, and multimodal physiotherapy, cognitive-behavioural interventions, massage, manipulations, laser therapy, and to some extent also TNS appear to have an effect on CNP. However, sufficient evidence for application of a specific physiotherapy modality or aiming at a specific patient subgroup is not available.
