Action and lumbar forces during hospital bed handling: A comparative study.
Article in Work (Reading, Mass.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BackgroundNursing staff show a higher-than-average prevalence of musculoskeletal disorders compared with other occupational groups. Moving hospital beds is among the most physically demanding nursing tasks. However, the influence of hospital bed design on the musculoskeletal strain experienced by nursing personnel during bed movement has not been sufficiently investigated.ObjectiveThis study examined the action and compressive forces (L5/S1) generated while moving twelve different hospital beds.MethodsEight participants moved the beds along a test course resembling a hospital ward. Action forces were measured using three-dimensional force measurement grips, and a motion analysis system recorded the participants' postures during the task. Based on these recordings, compressive forces at the lumbosacral junction (L5/S1) were calculated using the biodynamic model "The Dortmunder".ResultsMedian peak action forces ranged from 157.3 N to 240.0 N during bed acceleration and from 49.6 N to 92.4 N during steady movement. In several cases, the calculated compressive forces at L5/S1 exceeded the guideline value of 1.8 kN for 60-year-old female employees, indicating a moderately to substantially increased load for nursing staff.ConclusionDesign features such as a fifth caster on the hospital bed can reduce physical strain. Bed movers or active casters should be employed for frequent bed transport, long-distance pushing, or when the staff includes older employees or individuals with preexisting musculoskeletal conditions.
