- The aim of the present study was to quantify the total duration per shift in which nurses work in a forward bending position over 20 degrees. Furthermore, the influence of several factors on the occurrence of sagittal trunk inclinations in nurses was investigated. Trunk postures were recorded for nine nursing home nurses from four German nursing homes and 18 hospital nurses from seven hospitals using the CUELA measurement system. A total of 79 shifts, 27 in nursing homes and 52 in hospitals, were analysed. All measurements were supported by video recordings. Specially developed software (WIDAAN 2.75) was used to synchronize the measurement data and video footage. The total duration of inclinations per shift was significantly affected by the working area (nursing home or hospital) with an increase of 25.3 min in nursing homes (95% confidence interval 2.4-48.2; P = 0.032). Another factor was the extent of personal basic care tasks performed by the nurses (P < 0.001). Nursing home nurses worked about twice as long per shift in a forward bending position compared with hospital nurses (112 versus 63 min; P < 0.001) and they assumed almost one-third more inclinations per shift (1541 versus 1170; P = 0.005). Nursing staff perform a large number of inclinations. The amount of time spent by nurses working in a forward bending position was highly dependent on the working area and the extent to which patients were in need of help. It is very likely that future preventive measures, focussing on reducing the huge amount of inclination, would reduce the physical stress in everyday nursing work substantially.

- Objectives:To examine the influence of the two following factors on the proportion of time that nurses spend in a forward-bending trunk posture: (i) the bed height during basic care activities at the bedside and (ii) the work method during basic care activities in the bathroom. A further aim was to examine the connection between the proportion of time spent in a forward-bending posture and the perceived exertion.Methods:Twelve nurses in a geriatric nursing home each performed a standardized care routine at the bedside and in the bathroom. The CUELA (German abbreviation for 'computer-Assisted recording and long-Term analysis of musculoskeletal loads') measuring system was used to record all trunk inclinations. Each participant conducted three tests with the bed at different heights (knee height, thigh height, and hip height) and in the bathroom, three tests were performed with different work methods (standing, kneeling, and sitting). After each test, participants rated their perceived exertion on the 15-point Borg scale (6 = no exertion at all and 20 = exhaustion).Results:If the bed was raised from knee to thigh level, the proportion of time spent in an upright position increased by 8.2% points. However, the effect was not significant (P = 0.193). Only when the bed was raised to hip height, there was a significant increase of 19.8% points (reference: thigh level; P = 0.003) and 28.0% points (reference: knee height; P < 0.001). Bathroom tests: compared with the standing work method, the kneeling and sitting work methods led to a significant increase in the proportion of time spent in an upright posture, by 19.4% points (P = 0.003) and 25.7% points (P < 0.001), respectively. The greater the proportion of time spent in an upright position, the lower the Borg rating (P < 0.001) awarded.Conclusions:The higher the proportion of time that nursing personnel work in an upright position, the less strenuous they perceive the work to be. Raising the bed to hip height and using a stool in the bathroom significantly increase the proportion of time that nursing personnel work in an upright position. Nursing staff can spend a considerably greater proportion of their time in an ergonomic posture if stools and height-Adjustable beds are provided in healthcare institutions.
