A scoping review of the use of exercise-based upper extremity injury prevention programs for industrial workers

Facilitators and Barriers to Implementing Interventions to Prevent Musculoskeletal Disorders in Blue-Collar Workers: A Scoping Review

PURPOSE

Blue-collar workers generally have less healthy lifestyles, poorer health, and a lower life expectancy than white-collar workers. At least in part this may be attributed to their work and working conditions. Employers increasingly provide interventions to improve health and wellbeing and prevent musculoskeletal disorders. However, they often do not reach blue-collar workers. The aim of this scoping review was to identify the facilitators for and barriers to implementing such interventions among blue-collar workers.

METHODS

A scoping review in which the study population of the selected studies consists of blue-collar workers (≥ 18 years old) in paid employment. Furthermore, included studies should report facilitators and barriers to implementing interventions to prevent musculoskeletal disorders. The literature search was conducted in six databases. The resulting studies were extracted with the help of the updated Consolidated Framework for Implementation Research.

RESULTS

15 articles were included; these were reviews, intervention studies, qualitative studies and process evaluations. A main facilitator was a participatory approach, which involves the blue-collar worker in the entire process of defining, developing, and implementing a multidimensional preventive intervention. The main barriers on the worker level were unfavorable worker characteristics and unsupportive behavior/attitudes. The main barriers on the organization level were a culture with a high production standard, a hierarchical culture, inflexible work, and an unsupportive attitude from the employer.

CONCLUSION

This review showed the multifaceted nature of implementation. A tailored implementation plan that involves the stakeholders (including workers) is important.

Stretching to Reduce Pain-Related Disability Among Echocardiographic and Interventional Laboratory Employees-A Pilot Study

Background

Stretching improves range of motion and changes the viscoelastic properties of muscle-tendon units. We hypothesized that a regular stretching program would reduce the functional consequences of pain for employees working in echocardiographic, ultrasound, and interventional laboratories. This exploratory, proof-of-concept study was meant to inform expectations for future randomized, controlled studies.

Methods

In this unblinded, nonrandomized, observational study, we enrolled 196 health care professionals working in the interventional and echocardiographic laboratories in the departments of cardiology and radiology at Mayo Clinic and Mayo Clinic Health System to perform 15-minute neck, upper extremity, low back, and lower extremity stretches for 1 year. The functional consequences of pain were self-reported by using the Disability of Arm, Shoulder, and Hand; Neck Disability Index; and Roland-Morris Questionnaire, which was administered at baseline and at 1 year to measure response to stretching. Monitoring with an assessment plan for injuries was undertaken. Employees who were pregnant, unable to do exercises, or under active orthopedic treatment, were excluded.

Results

Of the 196 enrolled, 68 (35%) provided complete data at both baseline and follow-up. The majority of participants were over 40 years (n = 51; 72%) and female (n = 51; 72%). Participants performed stretches for 120.5 (IQR, 52-184) days over the year. The number of days of doing the stretches was well distributed across the study period with median quarters 1, 2, 3, and 4 of 32 (19-51), 32 (20-51), 31 (17-45), and 32.5 (12-47) days, respectively. The majority of participants (52.3%) stretched before, 18.9% stretched during and 28.8% stretched after work. Self-reported upper extremity disability improved in the treatment group with a significant decrease in the median Disability of Arm, Shoulder, and Hand score (5.2 to 2.6; P = .002). There was an absolute 4% decrease in the Neck Disability Index score, between baseline and 1-year follow-up (10% to 6%, P = .017). There was not a significant change in the Roland-Morris Questionnaire from baseline to follow-up (1 to 0; P = .287). No participant reported any stretch-related injuries.

Conclusions

A routine stretching program may represent an attractive, low-cost, noninvasive option to reduce upper extremity musculoskeletal disability of employees working in the echocardiographic, ultrasound, and interventional laboratories. Larger randomized trials are needed to confirm the association.

Functional training improves the effectiveness of stretching programs for university cleaning staff

Purpose

The purpose of this study was to determine whether combining a structured stretching program with functional movement/body position training would yield additive effects on flexibility, ergonomic practices, and subjective pain levels for employees at high risk for work-related musculoskeletal disorders.

Design/methodology/approach

Nine control and 13 experimental university cleaning staff participated in a 10-week full-body stretching intervention led by undergraduate students. Experimental participants also engaged in functional movement/body position training once per week. Joint range of motion, task ergonomic form, pain level, and stretching motivation results were compared pre- and post-intervention.

Findings

Overall flexibility (+25.75 ± 3.33%) and task ergonomic form (+26.3 ± 10.5%) significantly improved and were negatively correlated with pain levels (r = −0.541 and r = −0.317, respectively). Experimental participants experienced greater improvements in shoulder (control: +16.8 ± 9.0%; experimental: +64.2 ± 11.5%) and hip (control: +31.4 ± 9.9%; experimental: +91.2 ± 19.9%) flexibility as well as in task-specific ergonomic form for vertical (control: +0.0 ± 5.3%; experimental: +35.2 ± 10.1%) and horizontal wiping (control: −4.7 ± 4.7%; experimental: +29.0 ± 7.8%). Intrinsic motivation was increased for both groups (+26.2 ± 15.4%).

Originality/value

Supplementing a workplace stretching program with functional movement/body position training has the potential to improve flexibility and decrease pain while simultaneously increasing the likelihood that cleaning staff will participate in self-directed stretching in the future. The intervention serves as a model for workplace health management and wellness-focused community building on university campuses who insource cleaning staff.
