Workplace interventions for neck pain in workers

Physical symptoms among professional gamers within eSports, a survey study

BACKGROUND

There is a need to establish the prevalence of self-reported physical symptoms such as pain in professional gamers (PGs) and to analyse whether there are correlations between lifestyle factors and self-reported physical symptoms. The purpose of this study was to analyse the prevalence of self-reported physical symptoms including eye-related problems in PGs. A further aim was to analyse the association between physical symptoms and lifestyle factors such as sleep time, play time and physical activity.

METHODS

This study was designed as a cross-sectional study with data based on an electronic survey, created specifically for this study, through discussion and screening of established validated questionnaires for physical symptoms in musculoskeletal conditions: the Karolinska Sleep Questionnaire and the Nordic Musculoskeletal Questionnaire. The survey comprised age and years of experience as a PG as descriptive variables, as well as questions on sleep, play time, physical activity and physical symptoms for the purpose of analysis. The directors of 10 professional gaming corporations were contacted by email with a link to the study-specific survey to distribute to all employees.

RESULTS

A total of 40 answers to the electronic survey were retrieved from 40 PGs, of which 62.5% (n = 25) had experienced at least one physical symptom in the three months prior to answering the survey. There was a significant association between playing time and physical symptoms (OR = 8.0; 95% CI 1.4-44.6, p = 0.018), where playing for more than 35 h a week was positively associated with eight times higher odds of experiencing physical symptoms.

CONCLUSION

There is a high prevalence of physical symptoms, such as headache and eye symptoms, in professional eSports gamers. There was an association between playing more than 35 h per week with the prevalence of physical symptoms.

The Web-Based Pain-at-Work Toolkit With Telephone Support for Employees With Chronic or Persistent Pain: Protocol for a Cluster Randomized Feasibility Trial

BACKGROUND

Chronic or persistent pain affects one's ability to work or be productive at work, generating high societal and economic burden. However, the provision of work-related advice and support for people with chronic pain is variable or lacking. The Pain-at-Work (PAW) Toolkit was cocreated with people who live with pain, health care professionals, and employers. It aims to increase knowledge about employee rights and how to access support for managing a painful chronic condition in the workplace and provides advice on lifestyle behaviors that facilitate the management of chronic pain.

OBJECTIVE

We aimed to establish the feasibility of conducting a definitive cluster randomized controlled trial comparing access to the PAW Toolkit and telephone support calls from an occupational therapist (PAW) with treatment as usual (ie, standard support from their employer). Our primary outcomes are establishing parameters of feasibility, acceptability, usability, and safety of this digital workplace health intervention. We will assess the candidate primary and secondary outcomes' feasibility and test research processes for a definitive trial.

METHODS

This is an open-label, parallel 2-arm pragmatic feasibility cluster randomized controlled trial with exploratory health economics analysis and a nested qualitative interview study. We aim to recruit 120 participants from at least 8 workplace clusters (any type, >10 employees) in England. The recruitment of workplaces occurs via personal approach, and the recruitment of individual participants is web based. Eligible participants are vocationally active adults aged ≥18 years with internet access and self-reporting chronic pain interfering with their ability to undertake or enjoy productive work. A restricted 1:1 cluster-level randomization is used to allocate employment settings to PAW or treatment as usual; participants are unblinded to group allocation. Following site- and individual-level consent, participants complete a web-based baseline survey (time 0), including measures of work capacity, health and well-being, and health care resource use. Follow-up is performed at 3 months (time 1) and 6 months (time 2). Feasibility outcomes relate to recruitment; intervention fidelity (eg, delivery, reach, uptake, and engagement); retention; and follow-up. Qualitative evaluation (time 2) is mapped to the Capability, Opportunity, Motivation-Behavior model and will explore intervention acceptability to employees and employers, along with individual and contextual factors influencing the delivery and uptake of the intervention.

RESULTS

Ethics approval was obtained in March 2023. Trial recruitment began in June 2023.

CONCLUSIONS

The PAW Toolkit is the first evidence-based digital health intervention aimed at supporting the self-management of chronic or persistent pain at work. This study will inform the design of a definitive trial, including sample size estimation, approaches to cluster site identification, primary and secondary outcomes' selection, and the final health economic model. Findings will inform approaches for the future delivery of this digital health intervention.

The Association Between Shoulder Pain and Disability Among Saudi Office Workers

Background and objective Shoulder pain stands out as the most prevalent musculoskeletal issue that office workers face. This type of pain has been observed to be linked to various aspects of one's job. To address this concern, the current research endeavors to examine the impact of digital device use on the intensity of shoulder pain and the extent of disability experienced by office employees in Saudi Arabia. This study is driven by two principal objectives. Firstly, it aims to assess the overall occurrence of shoulder discomfort and functional limitations among the Saudi office worker population. Secondly, it seeks to draw comparisons between the parameters of the shoulder pain and disability scale and the amount of time spent using electronic screens. Methodology This cross-sectional descriptive study was conducted in Riyadh, Saudi Arabia. We recruited 150 participants to measure shoulder pain and disability among office workers. The study was carried out to determine the general frequency of shoulder discomfort and impairment by using the Shoulder Pain and Disability Index (SPADI). The survey was conducted online in June 2022 via Google Forms. The survey questions included data regarding age, sex, year of study, exercise, and duration of computer time per day (hours).  Results This study recruited 150 participants to measure shoulder pain and disability among office workers. The mean age of the cohort was 42.56 ± 2.56 years. Among the total participants, 90 (60%) were male, and 60 (40%) were female. We observed that pain parameters had a negative correlation of -0.008 with screen time. The participants who had high shoulder pain and disability scores were older in age and spent less than two hours on screens, which affects the correlation results, and hence we recommend performing a study involving the younger population working on screen for more than four hours to find the better correlation. At the same time, the shoulder disability score reported a correlation of 0.05, and the overall correlation between SPADI and screen time was observed to be 0.04. Based on these findings, the present study observed a weak correlation between SPADI and screen time. Conclusion These results suggest that while there may be some association between screen time and shoulder pain and disability, it is not substantial. Therefore, it is unlikely that screen time alone significantly contributes to the occurrence or severity of shoulder pain and disability among office workers. Additional factors and variables may need to be explored in future research to gain a more comprehensive understanding of this issue.

A Multi-component Intervention (NEXpro) Reduces Neck Pain-Related Work Productivity Loss: A Randomized Controlled Trial Among Swiss Office Workers

Purpose Neck pain is common among office workers and leads to work productivity loss. This study aimed to investigate the effect of a multi-component intervention on neck pain-related work productivity loss among Swiss office workers. Methods Office workers, aged 18-65 years, and without serious neck-related health problems were recruited from two organisations for our stepped-wedge cluster randomized controlled trial. The 12-week multi-component intervention included neck exercises, health-promotion information, and workplace ergonomics. The primary outcome of neck pain-related work productivity loss was measured using the Work Productivity and Activity Impairment Questionnaire and expressed as percentages of working time. In addition, we reported the weekly monetary value of neck pain-related work productivity loss. Data was analysed on an intention-to-treat basis using a generalized linear mixed-effects model. Results Data from 120 participants were analysed with 517 observations. At baseline, the mean age was 43.7 years (SD 9.8 years), 71.7% of participants were female (N = 86), about 80% (N = 95) reported mild to moderate neck pain, and neck pain-related work productivity loss was 12% of working time (absenteeism: 1.2%, presenteeism: 10.8%). We found an effect of our multi-component intervention on neck pain-related work productivity loss, with a marginal predicted mean reduction of 2.8 percentage points (b = -0.27; 95% CI: -0.54 to -0.001, p = 0.049). Weekly saved costs were Swiss Francs 27.40 per participant. Conclusions: Our study provides evidence for the effectiveness of a multi-component intervention to reduce neck pain-related work productivity loss with implications for employers, employees, and policy makers.Trial Registration ClinicalTrials.gov, NCT04169646.

Risk factors of neck disability in computer-using office workers: a cross-sectional study

TRIAL REGISTRATION

ClinicalTrials.gov identifier: NCT04821024.

Patterns of pain complaints and insomnia symptoms are associated with abusive supervision in the Norwegian working population: a latent class analysis

OBJECTIVES

Previous findings suggest that abusive supervision, i.e., subordinates' perceptions of their supervisor's behaviours as hostile (excluding physical aggression), may increase the risk of health complaints. In addition, recent data suggest that the FKBP5 genotype rs9470080 important in the regulation of cortisol release, influences the same outcome. Adding to this complexity, different health complaints often co-occur. The present study aimed to (1) uncover patterns of pain complaints and insomnia symptoms by using latent class analysis, (2) determine whether abusive supervision or FKBP5 rs9470080 was associated with these patterns, and (3) examine the interaction between abusive supervision and FKBP5 genotype regarding pain and insomnia symptoms.

METHODS

The data was collected through a national probability survey of 5,000 employees drawn from the National Central Employee Register by Statistics Norway. Abusive supervision was measured by a 5-item version of the Tepper's 2000 scale. Pain and insomnia symptoms were measured by 5 items reflecting pain and 3 items reflecting insomnia. The FKBP5 rs9470080 genotyping was carried out using TaqMan assay.

RESULTS

A total of 1,226 participants returned the questionnaire and the saliva kit sample. Based on these the latent class analyses revealed four classes based on response patterns of pain and insomnia symptoms. In the regression analysis, abusive supervision was a significant predictor for the response patterns. However, neither the FKBP5 nor the interaction between abusive supervision and FKBP5 showed significant contributions.

CONCLUSIONS

In conclusion, awareness of the association between abusive supervision and the revealed four pain- and insomnia subgroups, and what separates them, may be important for prognosis and an optimal follow-up for those affected.

The Pain at Work Toolkit for Employees with Chronic or Persistent Pain: A Collaborative-Participatory Study

Self-management tools for people with chronic or persistent pain tend to focus on symptom reporting, treatment programmes or exercise and do not address barriers to work, facilitators of work ability, or workplace pain self-management strategies. We developed the Pain at Work (PAW) toolkit, an evidence-based digital toolkit to provide advice on how employees can self-manage their pain at work. In a collaborative-participatory design, 4-step Agile methodology (N = 452) was used to co-create the toolkit with healthcare professionals, employers and people with chronic or persistent pain. Step 1: stakeholder consultation event (n = 27) established content and format; Step 2: online survey with employees who have persistent pain (n = 274) showed employees fear disclosing their condition, and commonly report discrimination and lack of line manager support. Step 3: online employer survey (n = 107) showed employers rarely provide self-management materials or education around managing pain at work, occupational health recommendations for reasonable adjustments are not always actioned, and pain-related stigma is common. Step 4: Toolkit development integrated findings and recommendations from Steps 1–3, and iterative expert peer review was conducted (n = 40). The PAW toolkit provides (a) evidence-based guidelines and signposting around work-capacity advice and support; (b) self-management strategies around working with chronic or persistent pain, (c) promotion of healthy lifestyles, and quality of life at work; (d) advice on adjustments to working environments and workplace solutions to facilitate work participation.

Is Neck Posture Subgroup in Late Adolescence a Risk Factor for Persistent Neck Pain in Young Adults? A Prospective Study

OBJECTIVE

The purpose of this study was to determine whether sagittal neck sitting posture subgroup membership in late adolescence was a risk factor for persistent neck pain (PNP) in young adults.

METHODS

There were 686 participants enrolled in the Raine Study at the 17- and 22-year follow-ups. At 17 years of age, posture was measured by photographs, and 4 subgroups of sitting neck posture were determined by cluster analysis. Height and weight were measured, and exercise frequency, depression, and PNP were assessed by questionnaire. At 22 years of age, participants answered questions about neck pain and occupation type. Logistic regression examined if neck posture subgroups at 17 years of age were a risk factor for PNP at 22 years of age, taking into account other factors.

RESULTS

Female sex (odds ratio [OR] = 1.75, 95% CI = 1.16-2.65) and PNP at 17 years of age (OR = 3.78, 95% CI = 2.57-5.57) were associated with PNP at 22 years of age. In females, neck posture subgroup at 17 years of age was a risk factor for PNP at 22 years of age. Compared with the upright subgroup, both the slumped thorax/forward head subgroup groups and the intermediate subgroup had decreased odds for PNP at 22 years of age (OR = 0.24, 95% CI = 0.08-0.76; OR = 0.38, 95% CI = 0.15-0.99, respectively). No association was found in males.

CONCLUSION

After taking into account PNP at 17 years, sitting neck posture at 17 was not a risk factor for PNP at 22 years of age in males, whereas in females, more relaxed postures (slumped thorax/forward head and Intermediate postures) were protective of neck pain compared with upright posture.

IMPACT

Females in late adolescence who sat in slumped thorax/forward head or intermediate posture rather than upright sitting posture had a lower risk of PNP as a young adult. The practice of generic public health messages to sit up straight to prevent neck pain needs rethinking.

Workplace physiotherapy for musculoskeletal pain-relief in office workers: A pilot study

BACKGROUND

Musculoskeletal pain is highly prevalent among office workers and causes high costs to the public health system. Strategies including education and exercise are recommended, with major benefits when conducted by physical therapists in the occupational environment. However, the required investment is uncommon among companies. This study aimed to evaluate the efficacy of a multimodal physiotherapy intervention to relieve musculoskeletal pain in office workers.

MATERIALS AND METHODS

The study employed a single group study with a pre-post study design and was conducted at Universidad San Jorge in 2018. Outcome variables were: workplace ergonomics (INSHT Guide), existence and severity of musculoskeletal disorders (Nordic Musculoskeletal Questionnaire), musculoskeletal pain intensity (Numeric Rating Scale), and Clinical Global Impression Scale. Office workers in a university setting (n = 24, 19 females) were assessed at baseline, after 4 weeks of in-person sessions and following 3 weeks of autonomous performance. The physiotherapy program included education, ergonomic supervision, self-treatment, strengthening, and stretching exercises. A repeated-measures ANOVA or Friedman test (with post hoc comparisons) and Chi-squared test were used to compare the study variables.

RESULTS

At baseline, cervical spine (54%), shoulder (42%), and lumbar regions (37.5%) were the most symptomatic regions according to the Nordic Musculoskeletal Questionnaire. Even if the proportion of symptomatic areas did not decrease significantly after the intervention, a great reduction of musculoskeletal pain intensity was observed after the program in the cervical (P < 0.001), lower back (P = 0.005), shoulder (P = 0.006) regions, and in the overall pain level (P < 0.001).

CONCLUSIONS

These results support that a multimodal physiotherapy program can relieve work-related musculoskeletal pain in office workers and serve as a basis for future controlled trials.

Self-Reported Variables as Determinants of Upper Limb Musculoskeletal Symptoms in Assembly Line Workers

BACKGROUND

Assembly lines work is frequently associated to work-related upper limb musculoskeletal disorders. The related disability and absenteeism make it important to implement efficient health surveillance systems. The main objective of this study was to identify self-reported variables that can determine work-related upper limb musculoskeletal symptoms-discomfort/pain-during a 6-month follow-up.

METHODS

This was a prospective study with a 6-month follow-up period, performed in an assembly line. Upper limb musculoskeletal discomfort/pain was assessed through the presence of self-reported symptoms. Uni- and multivariate logistic regression analyses were used to evaluate which self-reported variables were associated to upper limb symptoms after 6 months at the present and to upper limbs symptoms in the past month.

RESULTS

Of the 200 workers at baseline, 145 replied to the survey after 6 months. For both outcomes, "having upper limb symptoms during the previous 6 months" and "education" were possible predictors.

CONCLUSION

Our results suggest that having previous upper limb symptoms was related to its maintenance after 6 months, sustaining it as a specific determinant. It can be a hypothesis that this population had mainly workers with chronic symptoms, although our results give only limited support to self-reported indicators as determinants for upper limb symptoms. Nevertheless, the development of an efficient health surveillance system for high demanding jobs should implicate self-reported indicators, but also clinical and work conditions assessment should be accounted on the future.

Return on Investment (ROI) and Development of a Workplace Disability Management Program in a Hospital-A Pilot Evaluation Study

The progressive ageing of the working population and the increase in related chronic diseases tend to affect working capacity. The aim of this study was to evaluate a Workplace Disability Management Program (WDMP) within a pediatric hospital. Absenteeism due to healthcare workers’ (HCWs) pre- and post- WDMP and the related costs were used for the program evaluation. The Return on Investment (ROI), the Break-Even Analysis (BEA) and the value of the average annual productivity of HCWs who took advantage of the Disability Management (DM) interventions to assess the economic impact of the program, were also used. The HCWs enrolled in the program were 131 (approximately 4% of hospital staff), of which 89.7% females and with an average age of 50.4 years (SD ± 8.99). Sick leave days of the HCWs involved decreased by 66.6% in the year following the end of WDMP compared to the previous one (p < 0.001). The total estimated cost reduction of absenteeism is 427,896€ over a year. ROI was equal to 27.66€. BEA indicated that the break-even point was reached by implementing the program on 3.27 HCWs. The program evaluation demonstrated the particular effectiveness of the implemented WDMP model, acting positively on the variables that affect productivity and the limitation to work.

Occupational advice to help people return to work following lower limb arthroplasty: the OPAL intervention mapping study

BACKGROUND

Hip and knee replacements are regularly carried out for patients who work. There is little evidence about these patients' needs and the factors influencing their return to work. There is a paucity of guidance to help patients return to work after surgery and a need for structured occupational advice to enable them to return to work safely and effectively.

OBJECTIVES

To develop an occupational advice intervention to support early recovery to usual activities including work that is tailored to the requirements of patients undergoing hip or knee replacements. To test the acceptability, practicality and feasibility of this intervention within current care frameworks.

DESIGN

An intervention mapping approach was used to develop the intervention. The research methods employed were rapid evidence synthesis, qualitative interviews with patients and stakeholders, a prospective cohort study, a survey of clinical practice and a modified Delphi consensus process. The developed intervention was implemented and assessed during the final feasibility stage of the intervention mapping process.

SETTING

Orthopaedic departments in NHS secondary care.

PARTICIPANTS

Patients who were in work and intending to return to work following primary elective hip or knee replacement surgery, health-care professionals and employers.

INTERVENTIONS

Occupational advice intervention.

MAIN OUTCOME MEASURES

Development of an occupational advice intervention, fidelity of the developed intervention when delivered in a clinical setting, patient and clinician perspectives of the intervention and preliminary assessments of intervention effectiveness and cost.

RESULTS

A cohort study (154 patients), 110 stakeholder interviews, a survey of practice (152 respondents) and evidence synthesis provided the necessary information to develop the intervention. The intervention included information resources, a personalised return-to-work plan and co-ordination from the health-care team to support the delivery of 13 patient and 20 staff performance objectives. To support delivery, a range of tools (e.g. occupational checklists, patient workbooks and employer information), roles (e.g. return-to-work co-ordinator) and training resources were created. Feasibility was assessed for 21 of the 26 patients recruited from three NHS trusts. Adherence to the defined performance objectives was 75% for patient performance objectives and 74% for staff performance objectives. The intervention was generally well received, although the short time frame available for implementation and concurrent research evaluation led to some confusion among patients and those delivering the intervention regarding its purpose and the roles and responsibilities of key staff.

LIMITATIONS

Implementation and uptake of the intervention was not standardised and was limited by the study time frame. Evaluation of the intervention involved a small number of patients, which limited the ability to assess it.

CONCLUSIONS

The developed occupational advice intervention supports best practice. Evaluation demonstrated good rates of adherence against defined performance objectives. However, a number of operational and implementation issues require further attention.

FUTURE WORK

The intervention warrants a randomised controlled trial to assess its clinical effectiveness and cost-effectiveness to improve rates and timing of sustained return to work after surgery. This research should include the development of a robust implementation strategy to ensure that adoption is sustained.

The use of the PARIHS framework in implementation research and practice-a citation analysis of the literature

BACKGROUND

The Promoting Action on Research Implementation in Health Services (PARIHS) framework was developed two decades ago and conceptualizes successful implementation (SI) as a function (f) of the evidence (E) nature and type, context (C) quality, and the facilitation (F), [SI = f (E,C,F)]. Despite a growing number of citations of theoretical frameworks including PARIHS, details of how theoretical frameworks are used remains largely unknown. This review aimed to enhance the understanding of the breadth and depth of the use of the PARIHS framework.

METHODS

This citation analysis commenced from four core articles representing the key stages of the framework's development. The citation search was performed in Web of Science and Scopus. After exclusion, we undertook an initial assessment aimed to identify articles using PARIHS and not only referencing any of the core articles. To assess this, all articles were read in full. Further data extraction included capturing information about where (country/countries and setting/s) PARIHS had been used, as well as categorizing how the framework was applied. Also, strengths and weaknesses, as well as efforts to validate the framework, were explored in detail.

RESULTS

The citation search yielded 1613 articles. After applying exclusion criteria, 1475 articles were read in full, and the initial assessment yielded a total of 367 articles reported to have used the PARIHS framework. These articles were included for data extraction. The framework had been used in a variety of settings and in both high-, middle-, and low-income countries. With regard to types of use, 32% used PARIHS in planning and delivering an intervention, 50% in data analysis, 55% in the evaluation of study findings, and/or 37% in any other way. Further analysis showed that its actual application was frequently partial and generally not well elaborated.

CONCLUSIONS

In line with previous citation analysis of the use of theoretical frameworks in implementation science, we also found a rather superficial description of the use of PARIHS. Thus, we propose the development and adoption of reporting guidelines on how framework(s) are used in implementation studies, with the expectation that this will enhance the maturity of implementation science.

On-site multi-component intervention to improve productivity and reduce the economic and personal burden of neck pain in Swiss office-workers (NEXpro): protocol for a cluster-randomized controlled trial

Background

Non-specific neck pain and headache are major economic and individual burden in office-workers. The aim of this study is to investigate the effect of a multi-component intervention combining workstation ergonomics, health promotion information group workshops, neck exercises, and an app to enhance intervention adherence to assess possible reductions in the economic and individual burden of prevalent and incident neck pain and headache in office workers.

Methods/design

This study is a stepped wedge cluster-randomized controlled trial. Eligible participants will be any office-worker aged 18–65 years from two Swiss organisations in the Cantons of Zurich and Aargau, working more than 25 h a week in predominantly sedentary office work and without serious health conditions of the neck. One hundred twenty voluntary participants will be assigned to 15 clusters which, at randomly selected time steps, switch from the control to the intervention group. The intervention will last 12 weeks and comprises workstation ergonomics, health promotion information group workshops, neck exercises and an adherence app. The primary outcome will be health-related productivity losses (presenteeism, absenteeism) using the Work Productivity and Activity Impairment Questionnaire. Secondary outcomes are neck disability and pain (measured by the Neck Disability Index, and muscle strength and endurance measures), headache (measured by the short-form headache impact test), psychosocial outcomes (e.g. job-stress index, Fear-Avoidance Beliefs Questionnaire), workplace outcomes (e.g. workstation ergonomics), adherence to intervention, and additional measures (e.g. care-seeking). Measurements will take place at baseline, 4 months, 8 months, and 12 months after commencement. Data will be analysed on an intention to treat basis and per protocol. Primary and secondary outcomes will be examined using linear mixed-effects models.

Discussion

To the authors’ knowledge, this study is the first that investigates the impact of a multi-component intervention combining current evidence of effective interventions with an adherence app to assess the potential benefits on productivity, prevalent and incident neck pain, and headache. The outcomes will impact the individual, their workplace, as well as private and public policy by offering evidence for treatment and prevention of neck pain and headache in office-workers.

Evidence-based occupational health and safety interventions: a comprehensive overview of reviews

OBJECTIVES

Occupational injuries and diseases are a huge public health problem and cause extensive suffering and loss of productivity. Nevertheless, many occupational health and safety (OHS) guidelines are still not based on the best available evidence. In the last decade, numerous systematic reviews on behavioural, relational and mixed interventions to reduce occupational injuries and diseases have been carried out, but a comprehensive synopsis is yet missing. The aim of this overview of reviews is to provide a comprehensive basis to inform evidence-based decision-making about interventions in the field of OHS.

METHODS

We conducted an overview of reviews. We searched MEDLINE (Ovid), the Cochrane Library (Wiley), epistemonikos.org and Scopus (Elsevier) for relevant systematic reviews published between January 2008 and June 2018. Two authors independently screened abstracts and full-text publications and determined the risk of bias of the included systematic reviews with the ROBIS (Risk of Bias in Systematic Reviews) tool.

RESULTS

We screened 2287 abstracts and 200 full-texts for eligibility. Finally, we included 25 systematic reviews with a low risk of bias for data synthesis and analysis. We identified systematic reviews on the prevention of occupational injuries, musculoskeletal, skin and lung diseases, occupational hearing impairment and interventions without specific target diseases. Several interventions led to consistently positive results on individual diseases; other interventions did not show any effects, or the studies are contradictory. We provide detailed results on all included interventions.

DISCUSSION

To our knowledge, this is the first comprehensive overview of behavioural, relational and mixed interventions and their effectiveness in preventing occupational injuries and diseases. It provides policymakers with an important basis for making evidence-based decisions on interventions in this field.

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.

Workplace-Based Exercise Intervention Improves Work Ability in Office Workers: A Cluster Randomised Controlled Trial

Neck pain is a burden to employers and employees amenable to improvement with neck/shoulder strengthening exercises. However, the benefits of such interventions on office workers' work ability remains unknown. This study evaluated the effects of a 12-week combined ergonomics and neck/shoulder strengthening exercise intervention (EET, n = 177, mean age 41.7 years, 26% female), versus a 12-week combined ergonomics and health promotion intervention (EHP, n = 173, mean age 43 years, 29% female) on work ability among office workers. Work ability was measured by a single question. Differences in the work ability score were analyzed using the intention-to-treat (ITT) and per-protocol (i.e., adherence ≥70%) analyses for between- and within-group differences at baseline, 12 weeks, and 12 months. A sub-group analysis was performed for neck cases, defined as reporting neck pain as ≥3 (out of 10). No significant between-group differences for work ability were observed in the general population, and subgroup of neck cases. A significant group-by-time interaction effect at 12 weeks and the trend for significance at 12 months favored the EET group in the per-protocol analysis of the neck cases. EET was effective in increasing work ability post-intervention and potentially, in the long-term, in symptomatic participants with ≥70% adherence to the intervention. However, EET was not superior to EHP.

International Classification of Functioning, Disability and Health in Vocational Rehabilitation: A Scoping Review of the State of the Field

Purpose The purposes of this study were to provide an outline of the existing literature on operationalization of the International Classification of Functioning, Disability and Health (ICF) within vocational rehabilitation (VR) and to explore the ICF utility within VR. Methods The process was undertaken in five stages according to a framework of scoping review. Screening and extraction of data were done by two independent reviewers, and data was summarized according to content analysis. Results Fifty papers (25 qualitative and 25 quantitative) were included. The operationalization of the ICF was described in four different ways: In total 18 (36%) papers described use of the ICF for structuring information, 8 (15%) for linking information to ICF, 12 (24%) for analysis of results, and 12 (24%) for development of a model. In total 15 (29%) papers described VR interventions involving stakeholders, whereas 32 (62%) were reviews. Forty of the papers described all the ICF components. Conclusions The review revealed use of the ICF within the field VR in 50 papers, and in various settings. The ICF framework was most often operationalized for structuring or linking information of functioning. A majority of papers were reviews and involved researchers only, whereas different stakeholders and VR professionals were involved in the interventions. In 40 papers all the ICF components were described, and the ICF was considered a useful tool to inform the VR professionals´ assessment of functioning. However, more research within VR is needed to standardize and ease the use of the ICF.

Ergonomic interventions for preventing work-related musculoskeletal disorders of the upper limb and neck among office workers

BACKGROUND

Work-related upper limb and neck musculoskeletal disorders (MSDs) are one of the most common occupational disorders worldwide. Studies have shown that the percentage of office workers that suffer from MSDs ranges from 20 to 60 per cent. The direct and indirect costs of work-related upper limb MSDs have been reported to be high in Europe, Australia, and the United States. Although ergonomic interventions are likely to reduce the risk of office workers developing work-related upper limb and neck MSDs, the evidence is unclear. This is an update of a Cochrane Review which was last published in 2012.

OBJECTIVES

To assess the effects of physical, cognitive and organisational ergonomic interventions, or combinations of those interventions for the prevention of work-related upper limb and neck MSDs among office workers.

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, CINAHL, Web of Science (Science Citation Index), SPORTDiscus, Embase, the US Centers for Disease Control and Prevention, the National Institute for Occupational Safety and Health database, and the World Health Organization's International Clinical Trials Registry Platform, to 10 October 2018.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of ergonomic interventions for preventing work-related upper limb or neck MSDs (or both) among office workers. We only included studies where the baseline prevalence of MSDs of the upper limb or neck, or both, was less than 25%.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed risk of bias. We included studies with relevant data that we judged to be sufficiently homogeneous regarding the interventions and outcomes in the meta-analysis. We assessed the overall quality of the evidence for each comparison using the GRADE approach.

MAIN RESULTS

We included 15 RCTs (2165 workers). We judged one study to have a low risk of bias and the remaining 14 studies to have a high risk of bias due to small numbers of participants and the potential for selection bias.Physical ergonomic interventionsThere is inconsistent evidence for arm supports and alternative computer mouse designs. There is moderate-quality evidence that an arm support with an alternative computer mouse (two studies) reduced the incidence of neck or shoulder MSDs (risk ratio (RR) 0.52; 95% confidence interval (CI) 0.27 to 0.99), but not the incidence of right upper limb MSDs (RR 0.73; 95% CI 0.32 to 1.66); and low-quality evidence that this intervention reduced neck or shoulder discomfort (standardised mean difference (SMD) -0.41; 95% CI -0.69 to -0.12) and right upper limb discomfort (SMD -0.34; 95% CI -0.63 to -0.06).There is moderate-quality evidence that the incidence of neck or shoulder and right upper limb disorders were not considerably reduced when comparing an alternative computer mouse and a conventional mouse (two studies; neck or shoulder: RR 0.62; 95% CI 0.19 to 2.00; right upper limb: RR 0.91; 95% CI 0.48 to 1.72), and also when comparing an arm support with a conventional mouse and a conventional mouse alone (two studies) (neck or shoulder: RR 0.91; 95% CI 0.12 to 6.98; right upper limb: RR 1.07; 95% CI 0.58 to 1.96).Workstation adjustment (one study) and sit-stand desks (one study) did not have an effect on upper limb pain or discomfort, compared to no intervention.Organisational ergonomic interventionsThere is very low-quality evidence that supplementary breaks (two studies) reduce discomfort of the neck (MD -0.25; 95% CI -0.40 to -0.11), right shoulder or upper arm (MD -0.33; 95% CI -0.46 to -0.19), and right forearm or wrist or hand (MD -0.18; 95% CI -0.29 to -0.08) among data entry workers.Training in ergonomic interventionsThere is low to very low-quality evidence in five studies that participatory and active training interventions may or may not prevent work-related MSDs of the upper limb or neck or both.Multifaceted ergonomic interventionsFor multifaceted interventions there is one study (very low-quality evidence) that showed no effect on any of the six upper limb pain outcomes measured in that study.

AUTHORS' CONCLUSIONS

We found inconsistent evidence that the use of an arm support or an alternative mouse may or may not reduce the incidence of neck or shoulder MSDs. For other physical ergonomic interventions there is no evidence of an effect. For organisational interventions, in the form of supplementary breaks, there is very low-quality evidence of an effect on upper limb discomfort. For training and multifaceted interventions there is no evidence of an effect on upper limb pain or discomfort. Further high-quality studies are needed to determine the effectiveness of these interventions among office workers.

[Development process of Evidence-based "Return-to-work Guidance in Occupational Health 2017"]

OBJECTIVE

"Return-to-work Guidance in Occupational Health 2017 (RTW Guidance 2017) " is the first occupational health guide in Japan that evaluates the quality of evidence and offers recommendations based on results of the systematic review of randomized controlled trials. Details of the systematic review of each review question (RQs) will be described separately. This article presents an overview of the method and process of developing the "RTW Guidance 2017."

MATERIALS AND METHODS

The guidance was developed following the previously-published "Method for developing evidence based occupational health guidance," which included the composition of a highly-transparent guidance developing group as well as the recruitment and selection of RQs. Using the Cochrane Library, PubMed, and Ichushi-Web, a literature search for the six RQs was conducted in January 2016 by partly modifying the search terms of the existing systematic review. Articles were selected according to the inclusion criteria, and the quality of evidence was evaluated using the GRADE approach. Meta-analysis was conducted for RQ2 and RQ4, and a qualitative systematic review was conducted for RQ5, RQ6, and cost-effectiveness. Recommendations were subsequently made after a thorough consideration for feasibility in Japan by examining the costs and available resources.

RESULTS

Based on a comprehensive literature search, eleven RQ2, four RQ4, one RQ5, and three RQ6 were selected. Support program for returning to work, such as "Re-work" for those who are temporarily not working due to musculoskeletal disorders or mental health disorder, was recommended based on moderate evidence (RQ2). For RQ4, the collaboration between occupational health practice and clinical practice was weakly recommended based on low evidence. For RQ5 that evaluated the usefulness of social support, intervention by the manager/co-worker was proposed as a "best practice statement" without indicating it as a recommendation. Work accommodation was weakly recommended based on low evidence in RQ6.

DISCUSSION AND CONCLUSION

From the result of systematic reviews, it was recommended for workers on sick leave more than four weeks regardless of sick leave and sickness absence that interventions during leave would improve work-related outcomes, such as earlier reinstatement. Although there is limited evidence regarding occupational health in Japan, it is important for many occupational health professionals to learn the method of developing guidance and to identify issues for future studies with priority in Japan.

Vocational rehabilitation for enhancing return-to-work in workers with traumatic upper limb injuries

BACKGROUND

Traumatic upper limb injury is a leading cause of work-related disability. After return-to-work (RTW), many survivors of injuries are able to regain a quality of life (QoL) comparable with the normal population. Since RTW plays an important role in economic productivity and regaining health-related QoL, enhancing RTW in workers with traumatic limb injuries is the primary goal of rehabilitation. Vocational rehabilitation has been commonly employed in the field of occupational safety and health to increase the number of injured people returning to the labour market, prevent illness, increase well-being, and reduce disability.

OBJECTIVES

To assess the effects of vocational rehabilitation programmes for enhancing RTW in workers with traumatic upper limb injuries.

SEARCH METHODS

This is an update of a Cochrane review previously published in 2013. We updated our searches of the following databases: the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 9), MEDLINE (to 30 August 2017), EMBASE (to 3 September 2017), CINAHL (to 6 September 2017), and PsycINFO (to 6 September 2017), and we handsearched the references lists of relevant review articles.

SELECTION CRITERIA

We aimed to include all randomised controlled trials (RCTs) comparing vocational rehabilitation with an alternative (control) intervention such as standard rehabilitation, a limited form of the vocational rehabilitation intervention (such as advice on RTW, referral information, or liaison with employer), or waiting-list controls.

DATA COLLECTION AND ANALYSIS

Two authors independently inspected abstracts, and we obtained full papers when necessary. When the two authors disagreed about the inclusion of a study, we resolved disagreements by discussion. A third author arbitrated when necessary.

MAIN RESULTS

Our updated search identified 466 citations. Based on assessments of their titles and abstracts, we decided to evaluate the full texts of five records; however, none met our inclusion criteria.

AUTHORS' CONCLUSIONS

There is currently no high-quality evidence to support or refute the efficacy of vocational rehabilitation for enhancing RTW in workers with traumatic upper limb injuries. Since injured people in occupational settings frequently receive vocational rehabilitation with the aim of decreasing work disability, enhancing RTW, increasing productivity, and containing the welfare cost, further high-quality RCTs assessing the efficacy of vocational rehabilitation for workers with traumatic upper limb injury are needed to fill this gap in knowledge.

Chiropractic curriculum mapping and congruence of the evidence for workplace interventions in work-related neck pain

OBJECTIVE

The purpose of this study was to provide a best-synthesis summary of the literature for effective workplace health promotion interventions (WHPI) for work-related mechanical neck pain (MNP) and to determine the congruence between knowledge of WHPI for work-related MNP and coverage of MNP in the chiropractic postgraduate program at Macquarie University.

METHODS

A literature review was undertaken to determine effective WHPI for work-related MNP. We searched Cochrane Library, PubMed, EMBASE, CINAHL, and PEDro (from 1991 to 2016) for systematic reviews and meta-analyses. The PRISMA (2009) 27-item checklist was used to critically appraise included articles. Lectures, tutorials, and assessment tasks within the chiropractic postgraduate program were mapped to the literature review findings and analyzed.

RESULTS

There was moderate-quality evidence for multidimensional WHPI, including aspects of mental and physical functioning, activity performance and modifications, and environmental modifications, to reduce MNP and disability in workers, particularly in the long term. Education on coverage of MNP and effective WHPI for MNP was inadequately covered although congruent with synthesis of current literature. Education on body functions and structures and personal factors were the most commonly covered components.

CONCLUSION

Multidimensional WHPI, focusing on physical, mental, and environmental modifications, appear to reduce self-reported MNP primarily in office workers. There is adequate congruence between the chiropractic postgraduate program at Macquarie University and the published literature on some WHPI. However, there is inadequate coverage on aspects of MNP and effective WHPI for MNP, particularly those focusing on activity and participation and environmental factors.

Workplace Interventions to Prevent Disability from Both the Scientific and Practice Perspectives: A Comparison of Scientific Literature, Grey Literature and Stakeholder Observations

Purpose The significant individual and societal burden of work disability could be reduced if supportive workplace strategies could be added to evidence-based clinical treatment and rehabilitation to improve return-to-work (RTW) and other disability outcomes. The goal of this article is to summarize existing research on workplace interventions to prevent disability, relate these to employer disability management practices, and recommend future research priorities. Methods The authors participated in a year-long collaboration that ultimately led to an invited 3-day conference, Improving Research of Employer Practices to Prevent Disability, held October 14-16, 2015, in Hopkinton, Massachusetts, USA. The collaboration included a topical review of the literature, group conference calls to identify key areas and challenges, drafting of initial documents, review of industry publications, and a conference presentation that included feedback from peer researchers and a question/answer session with an expert panel with direct employer experience. Results Evidence from randomized trials and other research designs has shown general support for job modification, RTW coordination, and organizational support, but evidence is still lacking for interventions at a more granular level. Grey literature reports focused mainly on job re-design and work organization. Panel feedback focused on organizational readiness and the beliefs and values of senior managers as critical factors in facilitating changes to disability management practices. While the scientific literature is focused on facilitating improved coping and reducing discomforts for individual workers, the employer-directed grey literature is focused on making group-level changes to policies and procedures. Conclusions Future research might better target employer practices by tying interventions to positive workplace influences and determinants, by developing more participatory interventions and research designs, and by designing interventions that address factors of organizational change.

Mental Health Interventions in the Workplace and Work Outcomes: A Best-Evidence Synthesis of Systematic Reviews

Background:

Mental health issues in the workplace are a growing concern among organizations and policymakers, but it remains unclear what interventions are effective in preventing mental health problems and their associated organizational consequences. This synthesis reports on workplace mental health interventions that impact absenteeism, productivity and financial outcomes.

Objective:

To determine the level of evidence supporting mental health interventions as valuable to work outcomes.

Methods:

Databases were searched for systematic reviews between 2000 and 2012: Medline, EMBASE, the Cochrane Database of Systematic Reviews, DARE, CINAHL, PsycINFO and TRIP. Grey literature searches included health-evidence.ca, Rehab+, National Rehabilitation Information Center (NARIC), and Institute for Work and Health. The assessment of articles for inclusion criteria and methodological quality was conducted independently by two or more researchers, with differences resolved through consensus.

Results:

The search resulted in 3363 titles, of which 3248 were excluded following title/abstract review, with 115 articles retrieved for full-text review. 14 articles finally met the inclusion criteria and are summarized in this synthesis.

Conclusion:

There is moderate evidence for the effectiveness of workplace mental health interventions on improved workplace outcomes. Certain types of programs, such as those incorporating both mental and physical health interventions, multicomponent mental health and/or psychosocial interventions, and exposure in vivo containing interventions for particular anxiety disorders had a greater level of research evidence to support their effectiveness.

Are non-invasive interventions effective for the management of headaches associated with neck pain? An update of the Bone and Joint Decade Task Force on Neck Pain and Its Associated Disorders by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration

PURPOSE

To update findings of the 2000-2010 Bone and Joint Decade Task Force on Neck Pain and its Associated Disorders and evaluate the effectiveness of non-invasive and non-pharmacological interventions for the management of patients with headaches associated with neck pain (i.e., tension-type, cervicogenic, or whiplash-related headaches).

METHODS

We searched five databases from 1990 to 2015 for randomized controlled trials (RCTs), cohort studies, and case-control studies comparing non-invasive interventions with other interventions, placebo/sham, or no interventions. Random pairs of independent reviewers critically appraised eligible studies using the Scottish Intercollegiate Guidelines Network criteria to determine scientific admissibility. Studies with a low risk of bias were synthesized following best evidence synthesis principles.

RESULTS

We screened 17,236 citations, 15 studies were relevant, and 10 had a low risk of bias. The evidence suggests that episodic tension-type headaches should be managed with low load endurance craniocervical and cervicoscapular exercises. Patients with chronic tension-type headaches may also benefit from low load endurance craniocervical and cervicoscapular exercises; relaxation training with stress coping therapy; or multimodal care that includes spinal mobilization, craniocervical exercises, and postural correction. For cervicogenic headaches, low load endurance craniocervical and cervicoscapular exercises; or manual therapy (manipulation with or without mobilization) to the cervical and thoracic spine may also be helpful.

CONCLUSIONS

The management of headaches associated with neck pain should include exercise. Patients who suffer from chronic tension-type headaches may also benefit from relaxation training with stress coping therapy or multimodal care. Patients with cervicogenic headache may also benefit from a course of manual therapy.

Systematic Literature Review on ICF From 2001 to 2013 in the Nordic Countries Focusing on Clinical and Rehabilitation Context

We present a systematic review on International Classification of Functioning, Disability and Health (ICF) used in the Nordic countries from 2001 through 2013, describing and quantifying the development in utilization of ICF, and describe the extent to which the different components of the ICF have been used. A search was conducted in EMBASE, MEDLINE and PsycInfo. Papers from Nordic countries were included if ICF was mentioned in title or abstract. Papers were assigned to one of eight categories covering the wide rehabilitation area; furthermore, area of focus was assigned. Use of ICF components and intervention were coded in papers categorized as "clinical and/or rehabilitation contexts" or "non-clinical contexts". One hundred seventy papers were included, of these 99 papers were from the categories "clinical and/or rehabilitation contexts" or "non-clinical contexts". Forty-two percent of the 170 included papers were published in the period 2011 - 2013. There was an increase in ICF-relevant papers from 2001 to 2013, especially in the categories "clinical and/or rehabilitation contexts" and "non-clinical contexts". The most represented focus areas were neurology, musculoskeletal, and work-related areas. All five or at least four ICF components were mentioned in the results or discussions in most papers, and activity was most frequently mentioned.

Job demand and control interventions: a stakeholder-centered best-evidence synthesis of systematic reviews on workplace disability

BACKGROUND

Physical and psychological job demands in combination with the degree of control a worker has over task completion, play an important role in reducing stress. Occupational stress is an important, modifiable factor affecting work disability. However, the effectiveness of reducing job demands or increasing job control remains unclear, particularly for outcomes of interest to employers, such as absenteeism or productivity.

OBJECTIVE

This systematic review reports on job demand and control interventions that impact absenteeism, productivity and financial outcomes.

METHODS

A stakeholder-centered best-evidence synthesis was conducted with researcher and stakeholder collaboration throughout. Databases and grey literature were searched for systematic reviews between 2000 and 2012: Medline, EMBASE, the Cochrane Database of Systematic Reviews, DARE, CINAHL, PsycINFO, TRIP, health-evidence.ca, Rehab+, National Rehabilitation Information Center (NARIC), and Institute for Work and Health. Articles were assessed independently by two researchers for inclusion criteria and methodological quality. Differences were resolved through consensus.

RESULTS

The search resulted in 3363 unique titles. After review of abstracts, 115 articles were retained for full-text review. 11 articles finally met the inclusion criteria and are summarized in this synthesis. The best level of evidence we found indicates that multimodal job demand reductions for either at-work or off-work workers will reduce disability-related absenteeism.

CONCLUSION

In general, the impacts of interventions that aim to reduce job demands or increase job control can be positive for the organization in terms of reducing absenteeism, increasing productivity and cost-effectiveness. However, more high quality research is needed to further assess the relationships and quantify effect sizes for the interventions and outcomes reviewed in this study.

Are work disability prevention interventions effective for the management of neck pain or upper extremity disorders? A systematic review by the Ontario Protocol for Traffic Injury Management (OPTIMa) collaboration

PURPOSE

We conducted a systematic review to critically appraise and synthesize literature on the effectiveness of work disability prevention (WDP) interventions in workers with neck pain, whiplash-associated disorders (WAD), or upper extremity disorders.

METHODS

We searched electronic databases from 1990 to 2012. Random pairs of independent reviewers critically appraised eligible studies using the Scottish Intercollegiate Guidelines Network criteria. Scientifically admissible studies were summarized and synthesized following best-evidence synthesis methodology.

RESULTS

Of the 6,359 articles retrieved, 16 randomized controlled trials were eligible for critical appraisal and five were admissible. We found that a return-to-work coordination program (including workplace-based work hardening) was superior to clinic-based work hardening for persistent rotator cuff tendinitis. Workplace high-intensity strength training and workplace advice had similar outcomes for neck and shoulder pain. Mensendieck/Cesar postural exercises and strength and fitness exercises had similar outcomes for non-specific work-related upper limb complaints. Adding a brief job stress education program to a workplace ergonomic intervention was not beneficial for persistent upper extremity symptoms. Adding computer-prompted work breaks to ergonomic adjustments and workplace education benefited workers' recovery from recent work-related neck and upper extremity complaints.

CONCLUSIONS

At present, no firm conclusions can be drawn regarding the effectiveness of WDP interventions for managing neck pain, WAD, and upper extremity disorders. Our review suggests a return-to-work coordination program is more effective than clinic-based work hardening. Also, adding computer-prompted breaks to ergonomic and workplace interventions benefits workers' recovery. The current quality of evidence does not allow for a definitive evaluation of the effectiveness of ergonomic interventions.

Quebec Research on Work-related Musculoskeletal Disorders

This paper aimed to demonstrate the contribution of the research performed by the musculoskeletal disorders (MSD) Research Axis group of the Quebec Occupational Health and Safety Research Network towards better understanding of work-related MSD (WMSD) development and prevention. Although the group targets its work to the Quebec population, its work has significant impact around the world, placing MSD axis members and knowledge and expertise created in Quebec on the international map. Results from the contribution of members are relevant, primarily in the demonstration of the implication of physical workload as well as organizational and psychosocial work-related factors in the development of WMSDs. Also, members have demonstrated that gender, sex, social class, age and ethno-cultural groups interact in various ways with WMSD determinants. Efforts are devoted towards improving understanding of the physiological responses linked with MSDs, which could also lead to new workplace practices in rehabilitation. The group emphasizes the integration of prevention procedures from the design stage to the workplace intervention. Members have proposed research-based tools for best practices at work and also an original conceptual model as a key, novel element of a theoretical conceptualization of WMSDs. Moreover, the group focuses on improving WMSD surveillance, using multiple sources of information, providing information on newly identified health risks and developing new methods of assessing risk in order to effectively prevent disability in the working population. Finally, results from research of the MSD axis group have implications for orienting legal processes, improving legal recognition of MSDs as occupational diseases, and contributing to the evolution of legal thinking. However, much remains to be done. To that end, the group plans and encourages new initiatives for further advancement. In conclusion, the originality of the work places the group in a favourable position to address the complexity underlying WMSDs, combining expertise that enriches fundamental, clinical and population-based research.

Pain-related psychological cognitions and behaviours associated with sick leave due to neck pain: findings from the Nurses and Midwives e-Cohort Study

BACKGROUND

Sick leave due to neck pain (NP-SL) is costly and negatively impacts the productivity of the nursing and midwifery workforce. Identification of modifiable risk indicators is necessary to inform preventive efforts. This study aimed to investigate the role of pain-related psychological features (pain catastrophizing, fear of movement, and pain coping) in NP-SL alongside other potential risk indicators.

METHODS

A cross-sectional analysis of a large cohort study of Australian and New Zealand nurses and midwives, established between 1st April 2006 to 30th March 2008, was undertaken. Recruitment procedures adopted within each Nursing Council jurisdiction were governed by the individual regulatory authorities and their willingness to engage with the study. Invitations directed potential participants to a purpose-built internet-based survey, where study information was provided and consent requested. Once consent was obtained, a range of standardized tools combined into one comprehensive electronic questionnaire was elicited. Exposure variables assessed included pain characteristics and a broad range of psychological, psychosocial, occupational, general health and demographic factors. Two-way interactions between age and gender and candidate exposures were also assessed. Binary logistic regression was performed using manual backward stepwise elimination of non-significant terms.

RESULTS

The cohort included 4,903 currently working nurses or midwives aged 18-65 years. Of these, 2,481 (50.6%) reported neck pain in the preceding 12 months. Our sample comprised of 1,854 working nurses and midwives with neck pain in the preceding year who supplied sick leave data. Of these, 343 (18.5%) reported taking sick leave in the preceding year due to their neck pain. The final most parsimonious multivariable model demonstrated neck pain severity (adjusted odds ratio, [aOR] = 1.59), passive pain coping (aOR = 1.08) and fear of movement (aOR = 1.06) increased the likelihood of NP-SL in the previous year. Interactions between demographic and general health factors exhibited both protective and risk relationships with NP-SL, and there was no association between pain catastrophizing and NP-SL.

CONCLUSIONS

Findings demonstrate that sick leave due to neck pain was associated with pain severity, fear of movement and passive pain coping. In addition, there were complex interactions found between demographic and general health factors. These features represent potentially modifiable targets for preventive programs.

Vocational rehabilitation for enhancing return-to-work in workers with traumatic upper limb injuries

BACKGROUND

Traumatic upper limb injury is a leading cause of work-related disability. After return-to-work (RTW), many survivors of injuries are able to regain a quality of life (QoL) comparable with the normal population. Since RTW plays an important role in economic productivity and regaining health-related QoL, enhancing RTW in workers with traumatic limb injuries is the primary goal of rehabilitation. Vocational rehabilitation has been adapted in the field of occupational safety and health to enhance the number of injured people returning to the labour market, prevent illness, increase well-being, and reduce disability.

OBJECTIVES

To assess the effects of vocational rehabilitation programs in enhancing RTW of workers with traumatic upper limb injuries.

SEARCH METHODS

We searched OSH UPDATE databases (CISDOC, HSELINE, International Bibliographic, NIOSHTIC, NIOSHTIC-2, RILOSH) (up to 10 December 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) (2012, Issue 11), MEDLINE through PubMed (up to 15 November 2012), EMBASE (up to 28 November 2012), CINAHL (up to 5 May 2013), PsycINFO (up to 7 December 2012), and handsearched the reference lists of relevant review articles.

SELECTION CRITERIA

We aimed to include all randomised controlled trials (RCTs) comparing vocational rehabilitation with an alternative (control) intervention such as standard rehabilitation, an incomplete form of the vocational rehabilitation intervention (such as with limited advice on RTW, referral information, or liaison with employer), or waiting-list controls.

DATA COLLECTION AND ANALYSIS

Two authors independently inspected abstracts and we obtained full papers when necessary. When the two authors disagreed about the inclusion of a study, we resolved disagreements by discussion. A third author arbitrated when necessary.

MAIN RESULTS

Our search identified 332 citations. Based on assessments of their titles and abstracts, we decided to evaluate the full texts of 15 citations. In the end, none of these 15 citations met our inclusion criteria.

AUTHORS' CONCLUSIONS

There is currently no high-level evidence to support or refute the efficacy of vocational rehabilitation in enhancing RTW in workers with traumatic upper limb injuries. Since vocational rehabilitation has frequently been provided to injured people in occupational settings with the aim of decreasing work disability, enhancing RTW, increasing productivity, and containing the welfare cost, further high-quality RCTs assessing the efficacy of vocational rehabilitation for workers with traumatic upper limb injury are needed to fill this gap in knowledge.

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.

Effectiveness of an 8-week exercise programme on pain and specificity of neck muscle activity in patients with chronic neck pain: a randomized controlled study

BACKGROUND

Although exercise can be effective for relief of neck pain, little is known about the effect of exercise on the neural control of neck muscles.

METHODS

A randomized controlled trial was conducted on 46 women with chronic neck pain to investigate the immediate effectiveness of an 8-week exercise programme on pain and directional specificity of neck muscle activity. At baseline, the patients completed questionnaires including the neck disability index (NDI) and performed a circular contraction of their head in the horizontal plane at 15 N force, with continuous change in force direction in the range 0-360°. Electromyography (EMG) was recorded from the sternocleidomastoid (SCM) and splenius capitis (SCap) muscles. Tuning curves of the EMG amplitude were computed, which depicts muscle activity over a range of force directions. The mean point of the tuning curves defined a directional vector, which determined the specificity of muscle activity. Patients were randomly assigned either to a training or control group.

RESULTS

A significant between-group difference in the change in NDI was observed. A reduction in NDI was observed following training (pre: 18.2 ± 7.4; post: 14.1 ± 6.5; p < 0.01) but not for the control group (pre: 17.5 ± 6.3; post: 16.6 ± 7.4). The training group showed higher specificity of muscle activity post-intervention (pre: 18.6 ± 9.8%, post: 24.7 ± 14.3%; p < 0.05), whereas no change occurred for the control group (pre: 19.4 ± 11.9%, post: 18.2 ± 10.1%).

CONCLUSION

An exercise programme that aims to enhance motor control of the cervical spine improves the specificity of neck muscle activity and reduces pain and disability in patients with neck pain.
