The effects of height-adjustable beds in hospitals on the subsequent prevalence of lowback problems among nurses depend on the capacity to reduce low-back stress by bed-height adjustment.
This capacity was investigated in the present study.
Professional nurses performed patient-handling tasks at a standard and an individually chosen bed height.
Peak values and time integrals of spinal compression and shear forces were estimated with dynamic biomechanical modeling.
The bed-height adjustment led to lower values of time-integrated compression (average 8.8% lower), peak shear force (average 9.3% lower), and time-integrated shear force (average 18.1% lower).
No significance was found for the effect on peak compression, nor for the results for each individual task.
