Nonfatal Occupational Injury Rates and Musculoskeletal Symptoms among Housekeeping Employees of a Hospital in Texas

Objectives. To determine the prevalence of musculoskeletal disorders in hospital cleaners. Methods. Injury data on all hospital employees were extracted from occupational health records and compared. Additionally an interview-based modified Nordic Questionnaire (response rate 98.14%) was conducted. Results. The mean total injury rate for cleaners was 35.9 per 100 full-time equivalent (FTE), while that for other employees was 13.64 per 100 FTE. Slips/trips/falls and MMH contributed 4.39 and 2.37 per 100 FTE among cleaners and rest of the hospital employees, respectively. The most common type of injury was strain while the most common cause of injury was a striking object. Conclusion. The cleaners have higher injury rates and morbidity as compared to other employees of the hospital. The lower back was most commonly affected

A Community-Based Stress Management Program: Using Wearable Devices To Assess Whole Body Physiological Responses In Non-Laboratory Settings

A pragmatic breath-based intervention to benefit human performance and stress management is timely and valuable to individuals seeking holistic approaches for emotional regulation and optimizing compensatory reserve mechanisms. This protocol is designed to not only teach mind-body awareness but also to provide feedback utilizing physiological data and survey results. The primary findings of this study showed that heart coherence and alpha variables were significantly correlated after four weeks of the breath-based meditation stress protocol. Meditation and rhythmic breathing produced significant increases in alpha brain activity. These brain physiological responses conformed to the Pleth Variability Index (PVI) changes, suggesting the ability of the human body to enter into a meditative state and effectively manage stress. When assessed after four weeks of daily practicing the techniques employed in the stress management protocol, based on the Five Facet Mindfulness Questionnaire, subjects improved in applying mindfulness skills. The overall mindfulness score, Pleth variability index (PVI), and perfusion index (PI) increased after the 4-week intervention period. Results from electroencephalography (brain waves) were consistent with a meditative state during the post-study follow-up session. This provides evidence that wearable devices are feasible for data collection during a breath-based stress management intervention. This protocol can be easily and efficiently implemented into any study design in which physiological data are desired in a non-laboratory-based setting
