The effects of Ergorest arm supports on wrist angles and musculoskeletal strain in the neck-shoulder-arm region and electrical activity in the shoulder and arm muscles were studied during typing or the use of the mouse in work with a visual display unit (VDU). Twenty-one women were randomized into 3 groups (1 arm support, 2 arm supports, and control).(More)
The job demands on physical work capacity and the frequency of the firefighting and rescue tasks were rated by 156 professional firefighters (age range, 22 to 54 years) who responded to a questionnaire. Smoke-diving requiring the use of personal protective equipment was considered to demand most aerobic power. The clearing of debris with heavy manual tools,(More)
OBJECTIVES The aim of this study was to compare the psychophysiological strain related to a conventional shift schedule and new ergonomically improved two- and three-shift schedules using heart rate variability (HRV) analysis. The specific aim was to determine whether the introduced ergonomic shift arrangement had any positive effects on the(More)
Promoting well-being at work in the context of sustainable development is a complex and dynamic issue. To enhance sustainable well-being at work, organizational learning (OL) is one requirement. The purpose of this study was to identify and describe the characteristics of the learning program of the ergonomics ‘the Ergonetti’ that promote sustainable(More)
The psychophysical test, the rating of acceptable load (RAL) were used to assess acceptable weights for dynamic lifting in postal workers engaged in sorting parcels. The standard test (RALSt) and a work-simulating test (RALW) were administered to 103 volunteers: all experienced male sorters. In the RALSt, subjects selected the weight which would be(More)
The Ergonetti is a Finnish web-based university-level instructional learning program about ergonomics and workplace health promotion. The Ergonetti program is open to all applicants and it is intended to serve the needs of commercial enterprises. The aim of this study was to evaluate the Ergonetti program. Its evaluation was based on the experiences of the(More)
The aim of this study was to investigate differences in heart rate variability (HRV) reflecting the function of autonomic nervous system (ANS) and psycho-physiological strain associated with normal and extended work shifts in nursing work. Complete data were available from 51 female nurses with a mean age of 40 yr, and based on two comparable 36-h HRV(More)
The rating of acceptable load (RAL) attained with a standard test (RALSt) and a wrk-simulating test (RALW) for postal parcel sorting was related to anthropometric, muscle strength, and spinal mobility characteristics of 18 male sorters. The subjects comprised a subsample of 103 experienced male sorters who carried out the RAL tests at postal sorting(More)
