Evaluation of a Training Program to Reduce Stressful Trunk Postures in the Nursing Professions: A Pilot Study

Assessment of perceived patient comfort and ease of bedpan handling by caregivers, a cross-sectional survey

INTRODUCTION

Since its creation in the 18th century, bedpan has remained more or less the same. Its unique material composition varies from one model to another, but its shape remains relatively similar. The environment is one of the four pillars of the nursing paradigm. It is therefore essential to question this device in the nursing discipline.

AIM

To assess perceived patient comfort and ease of bedpan handling by nurses and their assistants.

METHOD

A cross-sectional survey via an online questionnaire was conducted among nurses and nursing assistants, nursing students, and health executives using the bedpan for their patients to assess their feelings and their level of satisfaction. The questionnaire asks professionals about the ease of handling the bedpan and the patient's perceived comfort.

RESULTS

431 responses were obtained out of 3007 persons interviewed (14.3%). 83.0% believe that the cause of poor elimination by the patient is often or very often due to physical discomfort on the bedpan. 62.6% find the installation of the bedpan rather tough or very difficult. 59.2% find the removal of the bedpan rather tough or very difficult.

DISCUSSION

Our study confirms our hypothesis and highlights a lack of comfort in the bedpan as perceived by professionals. This analysis is the first step in enabling the nurse researcher to support change in the transformation paradigm.

Efficacy of an Omaha system-based remote ergonomic intervention program on self-reported work-related musculoskeletal disorders (WMSDs) - A randomized controlled study

Purpose

Heavy biomechanical loadings at workplaces may lead to high risks of work-related musculoskeletal disorders. This study aimed to explore the efficacy of an Omaha System-based remote ergonomic intervention program on self-reported work-related musculoskeletal disorders among frontline nurses.

Materials and methods

From July to October 2020, 94 nurses with self-reported pain in one of the three body parts, i.e., neck, shoulder, and low back, were selected and were randomly divided into two groups. The intervention group received a newly developed remote program, where the control group received general information and guidance on health and life. Program outcome was evaluated by a quick exposure check approach.

Results

After 6 weeks, the intervention group exhibited significantly less stress in the low back, neck, and shoulder/forearms, compared to the control group (p < 0.05). In addition, the occurrence of awkward postures, such as extreme trunk flexion or twisting, was also significantly reduced (p < 0.05).

Conclusions

The newly developed Omaha System-based remote intervention program may be a valid alternative to traditional programs for frontline nurses during the COVID-19 pandemic, reducing biomechanical loadings and awkward postures during daily nursing operations.

Wearable Motion Capture Devices for the Prevention of Work-Related Musculoskeletal Disorders in Ergonomics-An Overview of Current Applications, Challenges, and Future Opportunities

Work-related musculoskeletal disorders (WMSDs) are a major contributor to disability worldwide and substantial societal costs. The use of wearable motion capture instruments has a role in preventing WMSDs by contributing to improvements in exposure and risk assessment and potentially improved effectiveness in work technique training. Given the versatile potential for wearables, this article aims to provide an overview of their application related to the prevention of WMSDs of the trunk and upper limbs and discusses challenges for the technology to support prevention measures and future opportunities, including future research needs. The relevant literature was identified from a screening of recent systematic literature reviews and overviews, and more recent studies were identified by a literature search using the Web of Science platform. Wearable technology enables continuous measurements of multiple body segments of superior accuracy and precision compared to observational tools. The technology also enables real-time visualization of exposures, automatic analyses, and real-time feedback to the user. While miniaturization and improved usability and wearability can expand the use also to more occupational settings and increase use among occupational safety and health practitioners, several fundamental challenges remain to be resolved. The future opportunities of increased usage of wearable motion capture devices for the prevention of work-related musculoskeletal disorders may require more international collaborations for creating common standards for measurements, analyses, and exposure metrics, which can be related to epidemiologically based risk categories for work-related musculoskeletal disorders.

The Effect of Interventions on Preventing Musculoskeletal Injuries Related to Nurses Work: Systematic Review

BACKGROUND

The 12-month prevalence of musculoskeletal disorders related to work (MDRW) in nurses rests between 71.8% to 84%, so it is urgent to develop preventive intervention programs with the purpose of avoiding negative physical, psychological, socioeconomic, and working aspects. There are several intervention programs aimed at preventing musculoskeletal disorders related to work for nurses, but few have successfully proven results. Despite the evidence pointing to the benefits of multidimensional intervention programs, it is essential to determine which interventions have positive effects on the prevention of this kind of disorder to create an effective intervention plan.

AIM

This review intends to identify the different interventions adopted in the prevention of musculoskeletal disorders related to work in nurses and to compare the effectiveness of these interventions, providing the appropriate and scientific basis for building an intervention to prevent musculoskeletal disorders in nurses.

METHOD

This Systematic Review was guided by the research question, "What are the effects of musculoskeletal disorders preventive interventions on nursing practice?" and carried out in different databases (MEDLINE, CINAHL, and Cochrane Central Register of Controlled Trials, SCOPUS, and Science Direct). Later, the results were submitted to the eligibility criteria, the appraisal quality of the papers, and the data synthesis was performed.

RESULTS

13 articles were identified for analysis. The interventions implemented to control the risk were: training patient-handling devices; ergonomics education; involving the management chain; handling protocol/algorithms; acquiring ergonomics equipment; and no-manual lifting.

CONCLUSIONS

The studies associated two or more interventions, the majority of which (11 studies) were training-handling devices and ergonomics education, therefore emerging as the most effective instruments in the prevention of MDRW. The studies did not associate interventions that cover all risk factors (individual, associated with the nature of the work, organizational, and psychological aspects). This systematic review can help with making recommendations for other studies that should associate organizational measures and prevention policies with physical exercise and other measures aimed at individual and psychosocial risk factors.

Health Promotion for Outpatient Careworkers in Germany

Due to ongoing demographic changes, the need for care is increasing in Germany. The number of outpatient care services is also rising, and with it, the number of employees in outpatient care, who are also continuously becoming older. Workplace health promotion (WHP) becomes relevant in this context, as it can reduce negative strain reactions and promote employees’ health. The aim of this study was (1) to reveal implemented WHP interventions in German outpatient care services; (2) to examine the potential challenges regarding a successful implementation of WHP measures; and (3) to illuminate further requests and needs experienced by outpatient careworkers. In qualitative field research, 30 semi-structured individual interviews were conducted with German caregivers, using the problem-centered interview method. The collected data were deductively and inductively evaluated and interpreted, using qualitative content analysis according to Mayring. Outpatient caregivers reported various WHP measures known from their workplaces, such as the provision of fruit baskets, programmes to increase physical activity, or a subsidy for a personal gym. They further reported WHP, such as back training, known from other care services. However, the respondents spoke of the challenges regarding the implementation or the use of WHP interventions in general. The most frequently named barriers were a lack of time after work and interventions that were only offered in their leisure time. In the same course, the participants still needed offers to increase physical activity, joint activities, or relaxation techniques. However, respondents highlighted that they preferred the interventions to take place during working hours. This way, they would also be more likely to take advantage of the interventions. The results of this study provide an insight into various WHP measures that already exist, or that are desirable for implementation with regard to caregivers’ needs. Subjectively perceived challenges for a successful implementation of WHP measures represent the importance of adjustments in the work organization of caregivers. It becomes clear that WHP is not yet established in the ambulant care sector, although it appears to be imperative for keeping caregivers healthy. Considering the different needs of employees, the results can provide a basis for the development of needs-based health promotion measures for caregivers.

The impact of different intensities and domains of physical activity on analgesic use and activity limitation in people with low back pain: a prospective cohort study with a one-year follow-up

BACKGROUND

Analgesics are the most common form of managing low back pain (LBP). No previous study has examined which domains and intensities of physical activity are most beneficial in reducing the frequency of analgesic use for LBP, and its related activity limitation.

METHODS

This cohort study forms part of the AUstralian Twin low BACK pain study, investigating the impact of physical activity on LBP. Information on demographics, LBP and health-related factors, including physical activity were collected at baseline. Data on the total counts of analgesic use and activity limitation for LBP were collected weekly for one-year. Negative binomial regression models were conducted separately for each type of physical activity. Results were presented as Incidence Rate Ratios (IRR) and 95% Confidence Intervals (CI).

RESULTS

From an initial sample of 366 participants, 86 participants reported counts of analgesic use and 140 recorded counts of activity limitation across the follow up period. The negative binomial regression models for analgesic use counts indicated moderate-vigorous physical activity (IRR 0·97, 95% C.I 0·96-0·99) and physical workload (IRR 1·02, 95% C.I 1·01-1·05) to be significant. For activity limitation counts, significant associations were shown for sedentary time (IRR 1·04, 95% C.I 1·01-1·09) and leisure activity (IRR 0·94, 95% C.I 0·81-0·99).

CONCLUSIONS

Our findings highlight the potential importance of supporting engagement in moderate-vigorous and leisure physical activity, as well as minimising sedentary time and physical workload to reduce the risk of activity limitation and the need for analgesic use in people with LBP.

Workplace health promotion interventions for nurses in Germany: a systematic review based on the RE-AIM framework

Background

The German health care system is faced with a serious shortage of nurses. This is associated, amongst other things, with difficult working conditions and work-related health burdens. Workplace health promotion (WHP) is considered a promising approach to promote the health of nurses. The present review aims to give an overview on existing interventions in different nursing settings (acute care hospitals, long-term care (LTC) facilities and home-based long-term care) in Germany.

Methods

A systematic literature search was conducted in PubMed and PubPsych. Studies were included if published after 2010 and provided data of intervention studies on workplace health promotion among nurses in Germany (RCTs, non-RCTs, non-controlled intervention studies and pilot studies). The setting in which the study was conducted (acute medical care hospital, inpatient LTC facilities, home-based LTC, cross-setting) as well as the health issue assessed (physical health, mental health and/or violence experience) were extracted. The intervention was reported against the background of the quality criteria for prevention measures of the statutory health insurers in Germany. The results of the studies were presented according to the RE-AIM framework.

Results

Eleven studies on WHP for nurses were included, whereof seven studies were conducted in acute medical care hospitals and four in LTC facilities. No study reported results on WHP for nurses working in the setting of home-based LTC. Most studies aimed at improving mental health. The intervention contents and forms of implementation were heterogeneous. According to the RE-AIM criteria, the reporting of most studies showed several limitations, especially a lack of reporting on Implementation and Adoption. Most studies showed no statistically significant effect on the respective outcomes (Effectiveness). Four studies reported results on Maintenance indicating a sustained effectiveness.

Conclusion

Despite the high relevance for health promotion for nurses, our review showed a striking lack of intervention studies in this field. From this we derive a high need of tailored interventions, taking into account the setting-specific development, implementation of WHP interventions for nurses. With regard to the evaluation, the RE-AIM criteria should be taken more into account in order to meet the requirements of evaluating complex interventions and thus contribute to evidence development of WHP in nursing. In terms of content, the topic of violence prevention and dealing with experiences of violence should also be taken into account. Regarding the settings, the working conditions and health burdens in LTC facilities, home-based LTC and acute medical hospitals must be considered.

Ergonomic Risk-prone Activities toward Nurses in the Intensive Care and Emergency Room

BACKGROUND: Nurses have the risk of ergonomic hazards in providing nursing care, especially with increasingly dynamic health services such as during Coronavirus disease-19 pandemic like today. AIM: The aim of the study was to evaluate activities prone to produce ergonomic risks during the implementation of nursing care in intensive care and emergency room (ER) of a hospital in Riau, Indonesia. METHODOLOGY: This study was conducted by observing the routine activities conducted by the nurses and using similar task group techniques equipped with Rapid Entire Body Assessment instrument. Those observed activities were obtained from 17 intensive care room nurses and ten ER nurses. There were six activities observed in the intensive care room: Bathing, transferring the patient, wounds dressing, taking blood samples for the AGDA examinations, as well as inserting the intravenous needle and electrocardiograms. Meanwhile, there were two activities observed in the ER: Transferring the patient and inserting the intravenous needle. RESULTS: The highest ergonomic risks activity in the intensive care room was bathing the patient with a total score of 13. At the ER, the highest risk score was transferring the patient with a total score of 12. Both activities were at level 4, indicating a high-risk condition. Thus, examinations and changes should be immediately initiated. CONCLUSION: The results are significant to be paid attention by the related parties at the hospital to facilitate some improvements immediately. In addition, the ergonomic approaches that can be suggested to the nurses are regular stretching, physical exercises, and applying ergonomic principles while working.

What Do We Know About Interventions to Prevent Low Back Injury and Pain Among Nurses and Nursing Students? A Scoping Review

STUDY BACKGROUND

Back injuries are common among nurses worldwide with lifetime prevalence of lower back pain ranging from 35% to 80%, making nursing a profession at great risk for back injuries.

PURPOSE

This systematic scoping review explored and mapped existing evidence regarding the prevention of low back injury and pain among nurses and nursing students.

METHODS

Using a scoping review methodology, six databases were searched initially in September 2017 and updated June 2020. Studies investigating interventions designed to reduce back injuries and pain among regulated nurses and student nurses, published in peer-review journals and written in English, were eligible for inclusion in this review. Quantitative, qualitative, and mixed methods studies of regulated nurses, nursing students, and nursing aides were included. Two independent reviewers screened, critically analysed studies using a quality appraisal tool, extracted data, and performed quality appraisals.

RESULTS

Two searches yielded 3,079 abstracts and after title, abstract and screening, our final synthesis was based on 48 research studies.

CONCLUSIONS

Forty years of research has demonstrated improvements in quality over time, the efficacy of interventions to prevent back injury and pain remains unclear, given the lack of high-quality studies. Further research, using multi-dimensional approaches and rigorous study designs, are needed.

Effects of Sensor Types and Angular Velocity Computational Methods in Field Measurements of Occupational Upper Arm and Trunk Postures and Movements

Accelerometer-based inclinometers have dominated kinematic measurements in previous field studies, while the use of inertial measurement units that additionally include gyroscopes is rapidly increasing. Recent laboratory studies suggest that these two sensor types and the two commonly used angular velocity computational methods may produce substantially different results. The aim of this study was, therefore, to evaluate the effects of sensor types and angular velocity computational methods on the measures of work postures and movements in a real occupational setting. Half-workday recordings of arm and trunk postures, and movements from 38 warehouse workers were compared using two sensor types: accelerometers versus accelerometers with gyroscopes-and using two angular velocity computational methods, i.e., inclination velocity versus generalized velocity. The results showed an overall small difference (<2° and value independent) for posture percentiles between the two sensor types, but substantial differences in movement percentiles both between the sensor types and between the angular computational methods. For example, the group mean of the 50th percentiles were for accelerometers: 71°/s (generalized velocity) and 33°/s (inclination velocity)-and for accelerometers with gyroscopes: 31°/s (generalized velocity) and 16°/s (inclination velocity). The significant effects of sensor types and angular computational methods on angular velocity measures in field work are important in inter-study comparisons and in comparisons to recommended threshold limit values.

ISOKINETIC TRUNK STRENGTH, VALIDITY, RELIABILITY, NORMATIVE DATA AND RELATION TO PHYSICAL PERFORMANCE AND LOW BACK PAIN: A REVIEW OF THE LITERATURE

BACKGROUND

Isokinetic testing of the trunk is ubiquitous in the literature and with training, however, there is a lack of normative data for adolescents and adult athletes.

PURPOSE

The purpose of the current review is to present and summarize data about isokinetic trunk strength assessment relative to young, adolescent and adult athletes. Testing position variations, reliability values by age groups, utilization of strength measures and normative data by age groups have been discussed. The information presented within this review are of practical importance for assessment of isokinetic trunk strength to appraise the athlete's current strength level and provide suitable conditioning training program.

STUDY DESIGN

Literature review.

METHODS

NCBI-PubMed, Web of Science, and SPORTDiscus were searched to identify relevant correlation and intervention studies/trials related to isokinetic testing of the trunk. Forty-two studies meeting the inclusion criteria were included in this literature review.

EVIDENCE SYNTHESIS

The validity of isokinetic trunk measures (i.e. peak torque; flexion/extension ratios) can be affected by a number of factors including whether the individual is tested in seated or standing position, which can alter the muscle length-tension relationship. Reliability is excellent for some strength measures and moderate to high for muscle endurance. Extension and concentric measures tend to have better reliability than flexion and eccentric measures respectively, while females show typically higher reliability scores than men due to the difficulty in controlling men's body position when testing. Normative data for various populations are provided.

CONCLUSIONS

Muscle assessment methods using an isokinetic dynamometer are considered reliable with high correlations to peak strength values and flexor/extensor ratios over age groups. However, caution should be exercised when interpreting position-specific isokinetic test results that measure trunk flexion (standing vs seated position). Still, there are indications that low-velocity movements are more reliable for measuring trunk strength. In adolescence, boys appear stronger than girls, with higher values for trunk extensors. Trunk flexors and extensors ratios decrease with growth. Data of isokinetic trunk muscle performance seems to be correlated not only to anthropometric parameters but also to sports discipline and training volume. The effects of sport on the muscular strength of the trunk may have both a preventive factor and a possible risk factor for low back pain. There is evidence for an association between high physical workloads and back injury.

Effectiveness of Lifestyle Health Promotion Interventions for Nurses: A Systematic Review

BACKGROUND

Prior research has investigated various strategies to improve health, wellbeing and the job-related outcomes of nurses. However, the scope of this evidence is not clear and the types of intervention most likely to have positive outcomes are unknown.

OBJECTIVE

To provide an overview and synthesis of the effectiveness of interventions conducted with the goal of improving health, wellbeing and the job-related outcomes of nurses.

METHODS

A systematic database search was conducted from January 2000 to December 2018, with pre-defined criteria (Cochrane Central Register of Controlled Trials; MEDLINE and PubMed; EMBASE; CINAHL; PsycINFO; and BioMed Central). In total, 136 intervention studies with a total sample of 16,129 participants (range 9-3381) were included and evaluated. Data extraction, quality assessment and risk of bias analyses were performed.

RESULTS

Studies included randomised controlled trials (RCTs; n = 52, 38%), randomised crossover design studies (n = 2, 1.5%) and non-randomised pre-post studies with a control group (n = 31, 23%) and without a control group (n = 51, 37.5%). The majority of interventions focused on education, physical activity, mindfulness, or relaxation. Thirty-seven (27%) studies had a multimodal intervention approach. On average, studies had relatively small samples (median = 61; mode = 30) and were conducted predominantly in North America (USA/Canada, n = 53). The findings were mixed overall, with some studies reporting benefits and others finding no effects. Dietary habits was the most successfully improved outcome (8/9), followed by indices of body composition (20/24), physical activity (PA) (11/14), and stress (49/66), with >70% of relevant studies in each of these categories reporting improvements. The lowest success rate was for work-related outcomes (16/32). Separate analysis of RCTs indicated that interventions that focus solely on education might be less likely to result in positive outcomes than interventions targeting behavioural change.

CONCLUSIONS

Interventions targeting diet, body composition, PA, or stress are most likely to have positive outcomes for nurses' health and/or wellbeing. The methodologically strongest evidence (RCTs) is available for body composition and stress. Interventions relying solely on educational approaches are least likely to be effective. Organisational outcomes appear to be more challenging to change with lifestyle intervention, likely requiring more complex solutions including changes to the work environment. There is a need for more high-quality evidence since many studies had moderate or high risk of bias and low reporting quality.

Low back pain among nursing professionals in Jeddah, Saudi Arabia: Prevalence and risk factors

BACKGROUND

Lower back pain (LBP) is often work-related and is commonly observed among nurses. LBP occurs below the 12th rib and above the gluteal fold. In nurses, back disorders are mainly associated with heavy physical activity, such as lifting and moving patients.

OBJECTIVE

The aim of the presented work is to evaluate the prevalence, risk factors, and associations of personal characteristics, general health status, and physical load with complaints of LBP.

METHODS

In this study, sixty nurses were randomly chosen to answer self-administered questionnaires. The results were analyzed using the SPSS system.

RESULTS

An incidence rate of 61.7% for LBP among nurses was noticed. Among the sites of injury, LBP predominated with a rate of 51.2%. Severity of injury mostly ranged between mild to moderate levels of severity, and 20% of the nurses with LBP were working in obstetrics and gynecology units. Our study also showed that 66.7% of the participating nurses had experienced LBP only after taking on nursing jobs.

CONCLUSIONS

The present study demonstrated that nurses working in Jeddah exhibit a high prevalence of lower back pain. In order to reduce the risk of work-related musculoskeletal disorders among nurses, the physical therapist's role is vital and nurses' practice of relaxation and stretching exercises in between work schedules is mandatory.

Reliability of isometric and isokinetic trunk flexor strength using a functional electromechanical dynamometer

Aim

To determine the absolute and relative reliability of functional trunk tests, using a functional electromechanical dynamometer to evaluate the isokinetic strength of trunk flexors and to determine the most reliable assessment condition, in order to compare the absolute and relative reliability of mean force and peak force of trunk flexors and to determine which isokinetic condition of evaluation is best related to the maximum isometric.

Methods

Test-retest of thirty-seven physically active male student volunteers who performed the different protocols, isometric contraction and the combination of three velocities (V₁ = 015 m s⁻¹ , V₂ = 0.30 m  s⁻¹, V₃ = 0.45 m s⁻¹) and two range of movement (R₁ = 25% cm ; R₂ = 50% cm) protocols.

Results

All protocols to evaluate trunk flexors showed an absolute reliability provided a stable repeatability for isometric and dynamic protocols with a coefficient of variation (CV) being below 10% and a high or very high relative reliability (0.69 < intraclass correlation coefficient [ICC] > 0.86). The more reliable strength manifestation (CV = 6.82%) to evaluate the concentric contraction of trunk flexors was mean force, with 0.15 m  s⁻¹ and short range of movement (V₁R₁) condition. The most reliable strength manifestation to evaluate the eccentric contraction of trunk flexors was peak force, with 0.15 m  s⁻¹ and a large range of movement (V₁R_2; CV = 5.07%), and the most reliable way to evaluate isometric trunk flexors was by peak force (CV = 7.72%). The mean force of eccentric trunk flexor strength with 0.45 m  s⁻¹ and short range of movement (V₃R₁) condition (r = 0.73) was best related to the maximum isometric contraction.

Conclusion

Functional electromechanical dynamometry is a reliable evaluation system for assessment of trunk flexor strength.

Implementing sensor technology applications for workplace health promotion: a needs assessment among workers with physically demanding work

Background

Workers with physically demanding work may be at risk for injury, illness or other adverse health outcomes due to exposure to different occupational hazards, especially at higher age. Sensor technology applications may be useful in the workplace to unobtrusively measure and monitor work exposures and provide workers with real-time feedback or access to data on demand. Many aspects might impede the implementation of sensor technology applications in the workplace, which should be taken into consideration for a successful implementation. Moreover, needs and preferences of workers regarding the use of sensor technology applications during work performance need to be identified. Therefore, the aim of this study was to identify worker needs and preferences regarding the use of sensor technology applications in the workplace.

Methods

Four on-site focus group sessions were conducted in four different companies among workers with physically demanding work (n = 30). Semi-structured interview schedules were used to identify which work exposures should be measured, by which kind of sensor technology applications, under which (pre)conditions, how to motivate long-term use of sensor technology applications, and which type of feedback is preferred. For data analysis, a content-analysis with an inductive approach was performed.

Results

Participants mentioned that they want to use wearable sensor technology applications to measure and monitor physical job demands, occupational heat stress, noise and fatigue. Factors associated with quality, comfort and perceived ease of use were identified as potential barriers for implementation in the workplace. Long-term motivation was attributed to the ability to manage and monitor work exposures, positive feedback and data ownership. Participants indicated a need to both receive real-time feedback and access to data on demand.

Conclusions

Sensor technology applications may support workers with physically demanding work to measure and monitor their work exposures. Potential barriers for implementation such as privacy aspects and quality, comfort and perceived ease of use of sensor technology applications need to be well considered to ensure successful implementation of sensor technology applications in the workplace.

The Back College for nurses - an evaluation of intermediate effects

BACKGROUND

Nursing staff and care workers run an increased risk of work related musculoskeletal disorders such as low back pain. The Institution for Statutory Accident Insurance and Prevention in the Health and Welfare Services (BGW) offers its insured persons the opportunity to participate in a three-week Back College with the aim of preventing them having to abandon their profession due to back problems. The aim of the study was to record the effectiveness and sustainability of the Back College on an intermediate basis (6 months).

METHODS

As part of a single-group pre-post measurement on three survey dates - at the start (T0) and end (T1) of rehabilitation and 6 months later (T2) - in 2013 all participants in the Back College at three locations were surveyed using a standard questionnaire. Wilcoxon signed-rank tests were performed to evaluate statistically significant changes.

RESULTS

For measurement dates T0 to T2 we had 570 complete datasets (response rate 70.81%). There was a significant decrease in reported back pain and the general state of health and quality of life index improved. Participants' emotional strain decreased and they showed an improved understanding of illness as well as of having acquired knowledge-based abilities and skills for dealing with the disease. After training, they recorded back-friendly behaviour in everyday life and opportunities to relieve strain on the spinal column were utilised at work more often. Participants' subjective assessment of their ability to work (Work Ability Index) improved.

CONCLUSION

The present study proved the intermediate effectiveness of the Back College curriculum. Whether these effects remain stable in the long term will be tested on the subsequent measurement date (T3, after 24 months).
