Manual handling of patients: role of kinesiophobia and catastrophizing in health workers with chronic low back pain

"Back Health 24/7/365"-A Novel, Comprehensive "One Size Fits All" Workplace Health Promotion Intervention for Occupational Back Health among Hospital Employees

BACKGROUND

Projects for workplace health promotion (WHP) for back pain traditionally focus exclusively on work-related but not on leisure-time stress on the spine. We developed a comprehensive WHP project on the back health of hospital workers regardless of the physical characteristics of their work and compared its effects on sedentary and physically active hospital workers.

METHODS

Study assessments were carried out before and six months after participation in the WHP intervention. The primary outcome parameter was back pain (Oswestry Disability Index, ODI). Anxiety (Generalized Anxiety Disorder-7), work ability (Work Ability Index), depression (Patient Health Questionnaire-9), stress (Perceived Stress Scale-10), and quality of life (Short Form-36) were assessed via questionnaires as secondary outcome parameters. Physical performance was measured via the 30 seconds Sit-to-Stand test (30secSTS).

RESULTS

Sixty-eight healthcare workers with non-specific back pain were included in the evaluation study of the WHP project "Back Health 24/7/365". After six months, back pain, physical performance, and self-perceived physical functioning (SF-36 Physical Functioning subscale) improved significantly in both groups. Not a single parameter showed an interaction effect with the group allocation.

CONCLUSIONS

A comprehensive WHP-intervention showed significant positive effects on hospital workers regardless of the physical characteristics of their work.

The Oswestry Disability Index is reflective of pain interference and mobility in children

PURPOSE

The 9-item Oswestry Disability Index version 2.1a (ODI-9) has never been formally validated in children. Our primary purpose was to evaluate the ODI-9 using the Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Pain Interference (PI) and Mobility Computer Adapted Test (CAT) and Pain Catastrophizing Scale for Children (PCS-C) as anchors to determine concurrent validity in children.

METHODS

We retrospectively reviewed cross-sectional patient-reported outcomes data using a convenience sample of children referred to a tertiary pediatric orthopedic institution for any spine condition from April 2021 to April 2022. The ODI-9, PI, and Mobility were completed at clinic intake in 2,097 children (1453 girls, 644 boys) aged 14.2 ± 2.6 years (range 5-18 years) during the same visit. The ODI-9 was administered when children or caregivers responded "yes" to the presence of back pain. The PCS-C was administered only when pain intensity was rated as "very severe" or "the worst imaginable" on Item 1 of the ODI-9 (n = 51).

RESULTS

Average ODI-9 scores were 18.3% ± 14.8%, indicating minimal disability (ODI-9 ≤ 20%). Moderate, statistically and clinically significant associations were seen between the ODI-9 and PI (r = 0.68, p < 0.001), the ODI-9 and Mobility (r = - 0.68, p < 0.001), and the ODI-9 and PCS-C (r = 0.59, p < 0.001).

CONCLUSION

Worse ODI-9 scores correlate with worse PROMIS PI scores, worse PROMIS Mobility scores, and worse PCS-C scores. The associations were moderate (PROMIS PI [r = 0.68], PROMIS Mobility [r = - 0.68], PCS-C [r = 0.59]).

Measurement precision of the Pain Catastrophizing Scale and its short forms in chronic low back pain

The Pain Catastrophizing Scale (PCS) is a widely studied tool to assess pain catastrophizing for chronic low back pain (LBP). Short forms of the PCS exist, but their measurement precision at individual level is unclear. This study aimed to analyze the Rasch psychometric characteristics of the PCS and three of its short forms (two 4-item and one 6-item) in a sample of 180 Italian-speaking patients with chronic LBP, and compare their measurement precision at the individual level. We performed a Rasch analysis on each version of the PCS and calculated test information functions (TIFs) to examine conditional measurement precision. Rasch analysis showed appropriate rating category functioning, unidimensionality, and acceptable fit to the Rasch model for all PCS versions. This represented a prerequisite for performing further advanced psychometric analyses. According to TIFs, the PCS full scale showed—at any score level—higher measurement precision in estimating individual pain catastrophizing than its short forms (which had unacceptably high standard errors of measurement). Our results show acceptable conditional precision of the PCS full scale in estimating pain catastrophizing. However, further studies are needed to confirm its diagnostic accuracy at individual level. On the other hand, the study warns against use of the three PCS short forms for clinical decision-making at the individual level.

Factors in the Use of Workplace Health Promotion on Back Health. Results of the Survey "German Health Update"

Background: The influence of the working environment on the back health of employees is well-documented. Many companies have begun to offer employees access to services to promote back health. Factors affecting the use of these offers at the population level have received little investigation to date. The current study examined the socio-demographic factors, physical activity and health-related factors, and work-related factors associated with the use of offers of workplace health promotion for back health in Germany. Materials and Methods: In the representative population-based cross-sectional survey "German Health Update" (GEDA 2014/2015-EHIS) conducted by the Robert Koch Institute, 12,072 employees aged 18-64 years old were surveyed from November 2014 to July 2015 regarding the use of back health services in their companies. In addition to socio-demographic factors, the survey examined working hours, physical activity in leisure time, health awareness, and subjective complaints in the lower back or other chronic back problems in the last 12 months. The interaction of these factors with the utilization of back health services was tested using multiple logistic regression models. Results: Women used back health services more often than men (women: 25.5%; men: 18.1%). Female gender was associated with part-time employment (OR 0.72) and a strong to very strong level of health awareness (OR 1.40). Male gender was associated with age between 30 and 44 years (OR 1.99) and 45-64 years (OR 2.02), low socioeconomic status (OR 0.48), endurance activity of <2.5 h per week (OR 0.62), and absence of lower back pain or other chronic back conditions for the last 12 months (OR 0.48). Conclusion: The present study is the first to provide findings regarding the factors associated with the utilization of workplace health promotion to promote back health at the population level, and from the perspective of employees in Germany. The results revealed that the relevant factors for participating in offers differ for women and men. To reach more employees, workplace health promotion offers for back health should be designed specifically for each individual, considering gender and age, working hours, health awareness and behavior, and health state.

Health, Physical Activity and Musculoskeletal Symptoms among Stone, Sand, and Gravel Mine Workers: Implications for Enhancing and Sustaining Worker Health and Safety

There is little data delineating relationships between health and worker musculoskeletal symptoms (MSS), particularly among stone, sand, and gravel mine (SSGM) workers. There is also little data detailing the relationships between physical activity and MSS among these workers. A cross-sectional study using data from 459 SSGM workers was completed. Logistic regression analyses assessed relationships between health factors, physical activity, and low back, neck, shoulder, and knee MSS. Those who reported their health as very good/excellent were less likely to suffer low back and knee MSS. Those who indicated their health was poor/fair were more likely to suffer shoulder, neck, and knee MSS. Obese workers were more likely to experience knee MSS and those who smoked in the past had higher odds of neck MSS. Vigorous physical activity was mostly protective, but those performing more than 5 h of moderate physical activity each week had greater odds of shoulder and neck MSS. Given these results, workers in SSGM may benefit from targeted interventions that bolster vigorous physical activity and improve health. Further, health protection efforts need to be initiated by SSGM operations to address work issues and to sustain health as job roles and work hours impacted MSS as well.
