“…In addition, nurses frequently have to work with forward bent, twisted, or awkward body postures (2). The mechanical load on intervertebral discs is therefore considerably high (3). Nursing is also known to involve psychosocial risk factors such as high demands on concentration, high responsibility, time pressure, and high needs for social support from supervisors and co-workers (4).…”

Elfering A, Grebner S, Semmer NK, Gerber H. Time control, catecholamines and back pain among young nurses. Scand J Work Environ Health 2002;28(6):386-393.Objectives This study had two objectives. First, it addressed concern with the contribution of work stressors and resources to the development of back pain, over and above the influence of biomechanical work factors. Second, using recent models about the role of the sympathetic-adrenal medullar system in musculoskeletal problems as its basis, it tested whether low-back pain is associated with higher levels of catecholamines.Methods Altogether 114 nurses filled out a questionnaire in their first year of practice and again one year later.In addition, in a subsample of 24 nurses studied intensively at follow-up, urinary catecholamines were assessed at noon, before the end of work, in the evening, and at corresponding times on a day off. Daily stressful experiences and daily mood were also recorded. ResultsWith control for baseline pain, biomechanical workload, and other potentially confounding variables, time control at the beginning of the study predicted low-back pain a year later. In the subsample, the epinephrine and norepinephrine levels were higher in those reporting more frequent episodes of back pain, the largest differences occurring at the end of work. In addition, control over stressful events at work was lower in this group.Conclusions Time control is a risk factor for low-back pain among nurses beyond the influence of physical work load. Low control at work may increase the activity of the sympathetic-adrenal medullar system, which seems to play an important role in the development of musculoskeletal pain.

“…A variety of sensor systems can be found in the literature, ranging from single attached sensors to complex systems. Despite guaranteeing continuity, the systems available often only record single body angles [10] or limit the ability to move around freely [11]. To overcome these limitations, a measurement system has been developed that records an individual's pattern of movement under realistic conditions with minimised interference; data analysis is facilitated by special software and the data can be linked to specific tasks (see below).…”

“…In contrast to goniometers, which typically measure the relative angle of two adhering segments inclinometers determine the absolute segment orientation in space. By combining an inclinometer and goniometer it becomes easy to imagine a setup where, e.g.,, pelvis inclination and hip and knee flexion-extension can be used to monitor indicators for e.g., lower back loading in lifting tasks (Morlock, 2000). In ergonomics, statistical descriptors such as 10 th , 50 th and 90 th percentile are computed to express the properties of the exposure (Hansson et al, 2006).…”
