WORK: A Journal of Prevention, Assessment & Rehabilitation is an interdisciplinary, international journal which publishes high quality peer-reviewed manuscripts covering the entire scope of the occupation of work. The journal's subtitle has been deliberately laid out: The first goal is the prevention of illness, injury, and disability. When this goal is not achievable, the attention focuses on assessment to design client-centered intervention, rehabilitation, treatment, or controls that use scientific evidence to support best practice.
WORK occasionally publishes thematic issues, but in general, issues cover a wide range of topics such as ergonomic considerations with children, youth and students, the challenges facing an aging workforce, workplace violence, injury management, performing artists, ergonomic product evaluations, and the awareness of the political, cultural, and environmental determinants of health related to work.
Dr. Karen Jacobs, the founding editor, and her editorial board especially encourage the publication of research studies, clinical practice, case study reports, as well as personal narratives and critical reflections of lived work experiences (autoethnographic/autobiographic scholarship),
Sounding Board commentaries and
Speaking of Research articles which provide the foundation for better understanding research to facilitate knowledge dissemination.
Narrative Reflections on Occupational Transitions, a new column, is for persons who have successfully transitioned into, between, or out of occupations to tell their stories in a narrative form. With an internationally renowned editorial board,
WORK maintains high standards in the evaluation and publication of manuscripts. All manuscripts are reviewed expeditiously and published in a timely manner.
WORK prides itself on being an author-friendly journal.
WORK celebrates its 25th anniversary in 2015.

Abstract: BACKGROUND: Hesitation to employ females for physically demanding jobs is often due to sex related physical abilities. A physical employment standard (PES) identifies individuals who are physically capable for work. OBJECTIVE: A database containing 300 + sources of physical performance tests (PFTs) will inform potential sex bias for PES development. METHODS: Weighted means and probability density curves illustrate the percentage overlap between male and female performance on PFT data from the armed forces of 11 countries and the open literature. Where female training data were available, the change in percentage overlap illustrates the potential for reduction in sex-related…differences. RESULTS: PFTs demonstrating the extremes of sex disparity were bench press (11 sources) and sit-ups (14 sources) with 9% and 93% overlap in performance, respectively. Training for bench press; pull ups; VO2max ; and upright pull improved female performance by 12%, 22%, 35%, and 23% respectively. This translated into narrowing the gap between male and female mean performance by 1%, 4%, 5%, and 10% respectively. CONCLUSIONS: The ability of PFT to predict performance is essential; however, PFTs with more overlap will facilitate development of PES with reduced sex bias. PFTs with the greatest potential for improvement in females are identified here.

Abstract: BACKGROUND: Physical employment standards (PES) ensure that candidates can demonstrate the physical capacity required to perform duties of work. However, movement competency, or an individual’s movement strategy, can relate to injury risk and safety, and therefore should be considered in PES. OBJECTIVE: Demonstrate the utility of using artificial intelligence (AI) to detect risk-potential of different movement strategies within PES. METHODS: Biomechanical analysis was used to calculate peak flexion angles and peak extensor moment about the lumbar spine during participants’ performance of a backboard lifting task. Lifts performed with relatively lower and higher exposure to postural and…moment loading on the spine were characterized as “low” or “high” exposure, respectively. An AI model including principal component and linear discriminant analyses was then trained to detect and classify backboard lifts as “low” or “high”. RESULTS: The AI model accurately classified over 85% of lifts as “low” or “high” exposure using only motion data as an input. CONCLUSIONS: This proof-of-principle demonstrates that movement competency can be assessed in PES using AI. Similar classification approaches could be used to improve the utility of PES as a musculoskeletal disorders (MSD) prevention tool by proactively identifying candidates at higher risk of MSD based on movement competency.

Abstract: BACKGROUND: The general physical task demands of law enforcement may suggest that police Officers are of similar fitness levels across cities, states and countries. OBJECTIVE: To investigate whether fitness levels of police Officers from two different United States (U.S.) Law Enforcement Agencies (LEA) are similar. METHODS: Retrospective data were analysed from two LEAs (LEA1 n = 79 and LEA2 n = 319). The data for Officers included: age, mass, 1-minute push-up repetitions, 1-minute sit-up repetitions, vertical jump height, 2.4 km run time (LEA 1) and 20-meter Multi-Stage Fitness Test results (LEA 2). Independent samples t-tests were used to compare…anthropometric and fitness data between LEA with significance set at 0.05. RESULTS: Officers from LEA1 weighed significantly less and performed significantly better than Officers from LEA2 on all fitness measures. When comparing male Officers alone, there was no statistical difference in age and mass; nonetheless, Officers from LEA1 significantly outperformed Officers from LEA2 on all fitness measures. CONCLUSION: While similarities / differences in job tasks performed between these two LEA are not known, the results from this study suggest differences in fitness between these two different U.S. LEA. Fitness standards and training protocols need to be developed and contextualized to each LEA’s specific population and needs.

Abstract: BACKGROUND: The Ottawa Paramedic Physical Ability Test (OPPAT™) is a physical employment standard for the paramedic sector. If a candidate is unsuccessful in meeting the OPPAT™ performance standard they should be provided with an appropriate accommodation, such as a strength and conditioning program, to improve performance. OBJECTIVE: Develop, implement and evaluate the effectiveness of a 4-week strength and conditioning program on improving OPPAT™ performance and associated fitness measures in paramedic candidates. METHODS: A 4-week strength and conditioning program was developed to focus on strength and power improvements. Based on initial OPPAT™ performance, participants were divided into…high and low performing groups; only the low performing group received the training intervention. OPPAT™ completion times and relevant fitness measures were compared pre- to post- intervention and between groups. RESULTS: Over the 4-weeks, peak lower body power and grip strength did not significantly improve in the intervention group, however OPPAT™ performance improved by 10%. The control group had significantly lower OPPAT™ completion times both pre- and post-intervention (19% and 11% lower respectively), as well as greater grip strength and peak lower body power. CONCLUSIONS: Implementation of a targeted strength and conditioning program successfully improved OPPAT™ performance in low performing candidates.

Abstract: OBJECTIVE: The purpose of this study was to examine the impact of applying six commonly-used and two proposed resting blood pressure (BP) cut-points to clear individuals for maximal exercise in non-clinical health, wellness, commercial fitness agencies and physically demanding occupation test sites. METHODS: Participants (n = 1670) completed the Physical Activity Readiness Questionnaire for Everyone (PAR-Q+) and had their resting BP measured. Individuals with a BP >160/90 mmHg were further screened for contraindications to exercise using the ePARMed-X+ (www.eparmedx.com ), all 1670 were cleared. There were no adverse events during or post exercise. RESULTS: The percentages of participants…cleared for each BP cut-point were: <130/80 mmHg (85.3%), <140/90 mmHg (93.4%), <144/90 mmHg (94.6%), <144/94 mmHg (96.3%), <150/100 mmHg (98.6%), <160/90 mmHg (95.6%), <160/94 mmHg (97.8%) and <160/100 mmHg (99.5%). Individuals who would not have been cleared without further screening were significantly older, had a higher BMI, or had a lower maximal oxygen consumption. CONCLUSIONS: Conservative or lower resting BP cut-points currently applied to clear individuals for maximal exercise provide an unnecessary barrier. For individuals categorized as low-to- moderate risk by evidence-based screening tools such as the PAR-Q+ and ePARmed-X+, we recommend a resting BP cut-point of <160/94 mmHg to clear for maximal exercise until sufficient evidence is amassed to support the increase to <160/100 mmHg.
