Background: Limited studies are available on the risk of trunk postural load to the prevalence of musculoskeletal disorders in nurses. The objective of this pilot study was to quantify and characterize trunk postural load in nurses with consideration of variation in the exposure in a hospital setting. Method: A comprehensive measurement approach combining continuous measurement by electro-goniometer, direct observation, physical activity monitor and self-report methods was applied to 8 female nurses to simultaneously record bending of the trunk, working activities, energy expenditure, heart rate, perceived workload and body musculoskeletal symptoms during sixteen 12-hour day shifts. Results: It was found that the percentage of patient care time spent on trunk flexion >20 degrees was 14.7% (p=0.001). The "high strain" trunk postures occurred three times every 10 minutes of the patient care time (p = 0.000), and nearly half of the resting intervals between two occurrences were less than 1 minute (p<0.023). Eighty percent of "high strain" trunk postures stayed within bending range of up to 15 degrees (p<0.01) and spent 68% of the total time length of "high strain" trunk postures (p<0.03). Furthermore, more than one-quarter of "high strain" trunk postures lasted more than 30 seconds. Frustration and temporal demand were found significantly correlated with some characteristics of trunk postures. Shift total energy expenditure intensity was found negatively correlated with body musculoskeletal discomforts. Conclusion: Patient care tasks require intense "high strain" trunk flexion. The trunk postural load may interact with the difficulty level of the task and working pace. The presented measurement strategy has the potential to quantify and characterize the trunk postural load, and can be particularly useful for assessing static postural load in field studies.
