Women are highly underrepresented in the construction skilled trades. In addition to facing the industry's well-known physical risks, women are subjected to discrimination, harassment, and skills under-utilization. As a result, tradeswomen have increased risk for injury, stress-related health effects, and high attrition rates from apprenticeship programs, thus perpetuating their minority status. Mentoring is a well-established technique for learning technical and personal navigation skills in new or challenging social environments. The investigators propose development and dissemination of a mentorship program through local unions of the International Association of Sheet Metal, Air, Rail and Transportation Workers (SMART), and evaluating its success in reducing women's injury and work stress, while improving retention.

The percentage of loss time claims receiving Loss of Earnings benefits at 3 months has continued to rise amongst injured workers in Ontario despite the Workplace Safety and Insurance Board (WSIB) approach of "Better at Work". The primary health services to address loss time claims associated with musculoskeletal injuries include the evidenced-based programs of care, occupational health assessment program and musculoskeletal specialty programs, however, these are set to be revised and relaunched in Q1 2023. Across treatment protocols there are challenges that, at least in part, appear to contribute to the increasing percentage of workers on full loss of earnings at 3 months include (1) inconsistent early identification of workers who should be triaged to various health services and (2) reliable determination of the optimal timing of referral to the most targeted care to enable a safe and sustainable return to work. The investigators aim to develop and evaluate a predictive assessment model to triage workers to the best service within the first 8 weeks of their claim to increase the rate of early return to work, with the long-term goal that the triage protocol becomes part of a person-centric protocol that reduces the duration of work-related disability. The investigators will develop and evaluate an assessment protocol for injured workers that enter any of the musculoskeletal-specific WSIB programs of care, which have been consolidated into a single program as of 2023. This study will be a prospective inception cohort design using data collected from injured workers receiving WSIB musculoskeletal programs of care services at CBI Health clinics in Ontario Canada. Worker data will be collected at intake to the program of care service and again approximately four and eight weeks after intake (or earlier if a worker completes the program of care). The investigators will complete data analysis in three steps including descriptive and bivariate associations, Maximum Likelihood-based Latent Profile Analysis, and evaluation of results against successful work outcomes and secondary outcomes. Qualitative data will be mined for alternative indicators of recovery / non-recovery. The study recruitment goal is 300 - 350 workers with complete follow-up within a 2-year period.

Patient handling is a major risk-factor for the development of musculoskeletal injuries in healthcare providers. To have a significant impact on injury reduction related to patient handling will require the incorporation of technology. This project is to investigate a piece of technology that has been designed to facilitate in-bed patient handling: The Vendlet. The purpose of this research project is to assess the ability of the Vendlet system outfitted on a Span-America Medical Systems (SAMS) bed to reduce the physical load on healthcare providers performing patient handling tasks. This evidence-based outcomes will be used to support the mitigation of the Vendlet from the European market into the Canadian market. The SAMS bed is currently available in North America and has several adjustable features to support patient transfer activities. The project will provide a biomechanical comparison of commonly used patient handling techniques performed using a SAMS bed outfitted with and without a Vendlet patient transfer device. This Vendlet technology has the potential to significantly reduce the musculoskeletal and joint strain of healthcare providers while handling patients.
NCT04913168
There is an urgent need for evidence-based interventions to reduce risk of musculoskeletal disorders (MSDs) and improve health and safety behaviors for low-income workers. Upstream interventions addressing these organizational characteristics and work experiences may be especially effective in preventing adverse health outcomes because they address underlying sources of elevated risk particularly important for low-wage workers. Low-wage workers have less schedule control, more irregular working hours, and shortened breaks due to time pressure to complete work tasks. The objective is to develop and test feasible intervention methods to modify the work organization and contribute to reductions in MSD risk, and improvements work-related well-being and job satisfaction. First, this study will identify characteristics of the work organization that can be feasibly modified through changes in management practices, based on interviews with food service managers and focus groups with workers. Second, the investigators will determine the feasibility and potential efficacy of an integrated TWH intervention in improving workers' ergonomic practices, MSD symptom, as well as in changing the work organization and environment related to work-related well-being and job satisfaction. The contribution of this study will be significant because it is expected to contribute to reducing disparities in these health outcomes by directly intervening on an underlying source of these disparities.

The term work-related musculoskeletal disorders (WRMDs) is defined according to the World Health Organization (WHO), as a wide range of inflammatory and degenerative diseases and disorders that result in pain and functional impairment. They arise when individuals are exposed to work activities and conditions that significantly contribute to their development or exacerbation, but which may not be their sole cause (1,2). Another definition The National Institute for Occupational Safety and Health defined WRMDs as "an injury of the muscles, tendons, ligaments, nerves, joints, cartilage, bones, or blood vessels in the arms, legs, head, neck, or back that is caused or aggravated by work tasks such as lifting, pushing, and pulling(3-5). They represent the second largest cause of short-term or temporary work disability after the common cold (6).Apart from lowering the quality of workers' life and reducing the productivity, WRMDs are the most expensive form of work disability, attributing to about 40% of all costs toward the treatment of work-related injuries(7). It is estimated that almost one-third of all cases of sick leave among health care workers are related to musculoskeletal disorders(8).According to the Bureau of Labor Statistics (BLS) in 2013, WRMDs cases accounted for 33% of all worker injury and illness cases(9). Most WRMSDs develop over time with usually, no single cause but various factors work in combination. According to the European Occupational Safety and Health Agency (EU-OSHA), the most common physical causes and organizational risk factors of musculoskeletal disorders (MSDs) include: * Prolonged sitting or standing in the same position * Performing the same task over and over * Continuing work while injured * Awkward and static postures * Load handling, especially when bending and twisting * Repetitive or forceful movements * Vibration * Insufficient work breaks(7,10-12).

Work-related musculoskeletal disorders are highly disabling. Therefore, finding preventive solutions is fundamental, in order to reduce the damages to workers and society. Therefore the objective of this study will be to evaluate the effect of passive and active pauses in the control of musculoskeletal complaints of office workers. This is a randomized controlled trial by cluster, which will be performed with 286 office workers (administrative sectors). Employees with physical disabilities will not be included in the study. The workers will be distributed into three groups: active control group, and the two intervention groups massage and workout gymnastics. The active control group and the other groups will be guidelines on ergonomic adjustments of the work station, and performing a 10-minute break every 50 minutes work. The intervention groups (passive and active) will receive different interventions: group massage in the chair and group gymnastics labor. The massage will be performed 2x per week for 10 minutes, and workout 2x per week for 15-20minutes. The primary outcomes assessed will be musculoskeletal complaints of pain intensity. And as a secondary outcome will be the ability to work, perception of ergonomic risk factors, psychosocial factors and fatigue, level of physical activity. Outcomes will be assessed at baseline and after 4 months. It is expected that exercise intervention (active pause) is more effective than passive pause (massage), and that pause and guidance can reduce musculoskeletal complaints, pain intensity, and other outcomes evaluated.

NCT03474705
Objectives: The aims are to 1) evaluate the clinical impact of eccentric training in female computer users with chronic NSP, 2) compare pressure hyperalgesia, temporal summation of pain (TSP), and conditioned pain modulation (CPM) in female office workers with and without NSP, and 3) assess changes in central pain responses after training. Methods: In part A, twenty office workers with NSP will be compared with 20 healthy controls. In part B, the NSP group will undergo a 5-week eccentric training program. Participants will report their pain intensity, and complete the Neck Disability Index, and the Disabilities of the Arm, Shoulder and Hand questionnaire. Pressure pain thresholds (PPTs) will be assessed over the neck and forearm. Cuff algometry will identify pain detection (PDT) and tolerance thresholds (PTT). TSP will be evaluated by visual analogue scale pain scores during 10 repetitive cuff stimulations. CPM will be calculated as the difference in PDT with and without a conditioning painful stimulus. Outcomes will be measured at baseline and post-intervention.
