Work demands and physical activity in hospital employees with different degrees of musculoskeletal pain: descriptive data from the STUNTH study, Norway.
Article in BMC musculoskeletal disorders, 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
backgroundHealthcare employees are frequently exposed to several risk factors for musculoskeletal pain at work, including high physical demands, psychological stressors, and high levels of occupational physical activity. We aimed to describe self-perceived work demands and device-measured physical activity at work among hospital employees across different occupations and clinical settings experiencing no pain, short-term pain, or long-lasting pain.
methodsWe used cross-sectional data on 1,413 hospital employees who participated in the first wave of the STUNTH (The Study of New Technology and Health among Hospital employees) cohort study. Physical activity was captured by two Axivity AX3 triaxial accelerometers placed on the thigh and lower back during up to seven consecutive days. Self-perceived work demands at the most demanding shift during the same period were assessed by NASA-Task Load Index (overall score and physical and mental demands subscales), ranging from 0 "Very low demands" to 100 "Very high demands". Musculoskeletal pain was measured by the Norwegian Pain Society Minimum Questionnaire, categorized by pain duration: no pain, short-term (during the last 7 days), or long-lasting (> 3 months). Quantile median regression models adjusted for age and sex were used to estimate work demands and physical activity according to different characteristics of musculoskeletal pain.
resultsThe overall prevalence of musculoskeletal pain was 75.7%, where 31.6% reported short-term pain during the previous seven days, and 44.1% reported having pain lasting > 3 months. Both perceived overall work demands and perceived physical work demands were higher for those reporting long-lasting musculoskeletal pain compared to those without pain, with a median difference of 5.8 (95% CI: 3.35 to 8.21) and 10.3 (95% CI: 1.51 to 19.02), respectively. There were no clear differences in mental demands or in device-measured physical activity between employees with or without musculoskeletal pain.
conclusionEmployees with long-lasting musculoskeletal pain reported higher perceived overall work demands and perceived physical demands, but no significant differences in proportion of time spent in device-measured physical activity types compared to employees without musculoskeletal pain.
