The Role of Perceived Job Exertion and Age as Moderators of the Relationship Between Gender and Upper Extremity Musculoskeletal Disability and Pain in Injured Workers

Effects of computer use on upper limb musculoskeletal disorders and function in academicians

Objectives. This study aimed to investigate the effects of academician's demographic characteristics and computer usage habits on upper limb musculoskeletal disorders (MSDs) and function. Methods. A cross-sectional observational study was conducted with 100 academicians. Data were collected using questionnaires, which included the patient-rated wrist evaluation questionnaire - Turkish version (PRWE-T), the Cornell musculoskeletal discomfort questionnaire - Turkish version (CMDQ-T), the upper extremity functional index - Turkish version (UEFI-T), demographic characteristics and average daily computer usage time. Results. A low-level significant correlation was found between the age of the individuals and the CMDQ-T forearm (p = 0.044; r = 0.202) and CMDQ-T wrist (p = 0.001; r = 0.337) scores. Women had higher CMDQ-T neck scores and lower UEFI-T scores than men (p < 0.05). Academicians who used computers for 6 h a day or more had higher PRWE-T and CMDQ-T neck, shoulder, upper arm and forearm scores, and had a lower UEFI-T score (p < 0.05). Conclusion. Neck, shoulder, upper arm and forearm symptoms were higher and upper extremity function was impaired in academicians who used computers for 6 h a day or more. Besides, gender and age were associated with upper limb MSDs and function, but occupation duration did not affect those outcomes in academicians.

Association Between Pain Coping and Symptoms of Anxiety and Depression, and Work Absenteeism in People With Upper Limb Musculoskeletal Disorders: A Systematic Review and Meta-analysis

OBJECTIVE

To determine the prospective association of pain coping strategies and symptoms of anxiety and depression with work absenteeism in people with upper limb musculoskeletal disorders.

DATA SOURCES

A systematic search of PubMed, Web of Science, Embase, Cochrane Library, and Scopus databases was conducted from inception to September 23, 2022.

STUDY SELECTION

Prospective observational studies of adults with upper limb musculoskeletal disorders were included. Included studies had to provide data on the association of pain coping strategies (catastrophizing, kinesiophobia, self-efficacy or fear avoidance) or symptoms of anxiety and depression with work absenteeism.

DATA EXTRACTION

Study selection, data extraction, and assessment of methodological quality (Newcastle Ottawa Scale) were performed by 2 independent authors. Random-effects models were used for quantitative synthesis.

DATA SYNTHESIS

Eighteen studies (n=12,393 participants) were included. Most studies (77.8%) reported at least 1 significant association between 1 or more exposure factors (pain coping strategies or symptoms of anxiety and depression) and work absenteeism. Meta-analyses showed a statistically significant correlation between the exposure factors of catastrophizing (r=0.28, 95% confidence interval [CI]: 0.15 to 0.40; P<.0001) and symptoms of anxiety and depression (r=0.23, 95% CI: 0.10 to 0.34; P=.0003) with work absenteeism. The correlation between self-efficacy and work absenteeism was non-significant (r=0.24, 95% CI: -0.02 to 0.47; P=.0747).

CONCLUSIONS

Rehabilitation teams should consider assessing catastrophizing and symptoms of anxiety and depression to identify patients at risk for work absenteeism. Addressing these variables may also be considered in return-to-work programs for individuals with upper limb disorders.

Investigation of the effects of a short opponens splint and structured hand exercise program in computer engineers with wrist pain: a randomized controlled trial

Objectives. This study aimed to examine the effects of a short opponens splint and hand exercise program on pain, hand functionality, daily activities, and work efficacy in computer engineers with wrist pain. Methods. Forty-five engineers were randomized into three groups: group 1 (n = 15) utilized both splints and exercises, group 2 (n = 15) engaged in exercises only and group 3 (n = 15) received no treatment, across 8 weeks, thrice weekly. Only exercises were applied to group 2 (n = 15). No treatment was applied for group 3 (n = 15). The progress of subjects was controlled periodically each week. Outcome measurements including the Jamar hand dynamometer, pinchmeter, nine-hole peg test (9-NHPT), visual analog scale, Boston carpal tunnel syndrome questionnaire and Michigan hand outcome questionnaire (MHQ) were evaluated pre and post treatment during the study period. Results. Comparing the outcome measurements of the three groups showed a statistically significant difference between them except for the 9-NHPT and MHQ pain and esthetics (p < 0.05). According to post-hoc tests, groups 1 and 2 had more significant differences than group 3. Also, there was no statistically significant difference in any parameter between group 1 and group 2 (p > 0.017). Conclusion. Non-restrictive minimal orthosis or exercise programs are advisable for individuals with wrist pain.

The importance of a healthy lifestyle despite chronic pain: Prospective cohort with 11-year register follow-up

The purpose of the study was to investigate to which extent a healthy lifestyle in female healthcare workers with chronic pain contributes to reducing the risk of disability pension. We conducted a prospective cohort study with an 11-year registry follow-up. Overall, 2386 Danish female healthcare workers with chronic pain completed a questionnaire about work and lifestyle (leisure-time physical activity, smoking, and body mass index (BMI)). Data on disability benefit payments were obtained from the Danish Register for Evaluation of Marginalization. Two models (minimally and fully adjusted for different potential confounders) were tested using the Cox proportional hazards model. During the follow-up period, 17.9% of the healthcare workers obtained disability pension. Low levels of leisure time physical activity (reference: moderate level) increased the risk of disability pension in the minimally (Hazard Ratio: 1.38 (95% CI: 1.14-1.69)) and fully adjusted models (Hazard Ratio: 1.27 (95% CI: 1.04-1.56)). Being highly physically active, as opposed to being moderately active, did not confer additional protection. Additionally, a positive association was observed between smoking and disability pension in the minimally adjusted model (Hazard Ratio: 1.27 (95% CI: 1.05-1.54)). BMI was not an influential factor. In female healthcare workers with chronic pain, at least moderate levels of physical activity is a protective factor for disability pension. Effective promotion strategies should be designed for both workplace and non-workplace settings.

Can Vitality and Mental Health Influence Upper Extremity Pain? A Prospective Cohort Study of 1185 Female Hospital Nurses

Musculoskeletal disorders of the upper extremity are among the most common occupational problems affecting nurses. The aim of this study was to analyze the prospective association between vitality and mental health and increased upper extremity pain intensity in female hospital nurses during a 1-year follow-up. A prospective cohort of 1185 female nurses from 19 hospitals in Denmark was conducted using baseline and 12-month follow-up questionnaires to identify potential associations between levels of vitality and mental health (SF-36 subscales) with pain intensity (0-10 scale) in the shoulder, elbow and hand/wrist regions. Associations were modeled using cumulative logistic regression. The fully adjusted model included the variables of age, baseline pain, body mass index, smoking status, years of occupation, leisure time physical activity level, number of daily patient transfers/handlings, as well as recognition and influence at work. The mean age was 48.3 (SD: 10.4) years. In the fully adjusted model, significant associations between low vitality levels and the odds of shoulder pain (OR = 1.96; 95%CI: 1.43-2.68) and hand/wrist pain (OR = 2.32; 95%CI: 1.58-3.42) were observed. Likewise, moderate levels of mental health was associated with increased odds of shoulder pain at follow-up (OR = 1.50; 95%CI: 1.16-1.93). These results provide an important incentive for nursing managers to assess vitality and mental health among hospital nurses and to consider this factor in prevention strategies to ensure good worker health and, by extension, high-quality care.

What Are Work-Related Predictors of Post-COVID-19 Home and Family Work Roles? A Cross-Sectional Survey

OBJECTIVE

To determine the extent to which pre-and post-COVID-19 work-related factors can explain post-COVID-19 home and family work roles.

METHODS

This study was a cross-sectional survey. The primary outcome measure was the Home and Family Work Roles Questionnaire. Descriptive statistical methods and multiple regression analyses were run. The significant predictors were further probed in a one-way analysis of covariance (ANCOVA) model with a Tukey posthoc correction.

RESULTS

In our sample of 1447 participants, the two significant predictors of post-COVID-19 home and family work roles were pre-pandemic paid job status (F [3, 1401] = 5.66, P < 0.001), and pre-COVID-19 home and family work roles (F [1, 1401] = 2509.26, P < 0.001).

CONCLUSION

Greater pre-pandemic home and family role responsibilities, full-time and part-time employment pre-COVID-19 were associated with greater post-COVID-19 home and family responsibilities.
