General description: the data of 40 office workers was collected to investigated a) the effect of time spent standing on low back and lower limb pain during a 1-hour laboratory-based task; b) the standing time after which a significant increase in pain is likely; and c) the individual, physical and psychosocial factors that predict pain.

METHODOLOGICAL INFORMATION
--------------------------

Description of methods used for collection/generation of data: 
Methods for collection data are available in the previous study: “Rodríguez-Romero B, Smith MD, Quintela-Del-Rio A, Johnston V. What Psychosocial and Physical Characteristics Differentiate Office Workers Who Develop Standing-Induced Low Back Pain? A Cross-Sectional Study. Int J Environ Res Public Health. 2020 Sep 28;17(19):7104. doi: 10.3390/ijerph17197104. PMID: 32998273; PMCID: PMC7579504. 

Software- or Instrument-specific information needed to interpret the data, including software and hardware version numbers:  SPSS version 25.0 (SPSS Inc., Chicago, Illinois, USA) and R version 4.0.5 (R Foundation for Statistical Computing, Vienna, Austria)
 
The statistical analysis includes: Descriptive statistics were computed for pain ratings over the 1-hour task (0, 15, 30, 45 and 60 minutes). At each timepoint, prevalence of pain for each location was comput-ed, and VAS scores were summarized as mean ± standard deviation and median (inter-quartile range). Appropriate tests for paired data were employed in bivariate analysis.Spearman’s correlations and a stepwise multivariate linear regression model were used.
Finally, in order to compare the consistency of the results, univariate and multivariate linear mixed-effects random-slope repeated measures models were also adjusted.

Environmental/experimental conditions:
A convenience sample of forty office workers was recruited from the local university and surrounding community via flyers, electronic noticeboards and social media to participate in this cross-sectional laboratory study.
Participants completed a series of self-report questionnaires and attended laboratory testing conducted by a trained physiotherapist.

Describe any quality-assurance procedures performed on the data:
Testing was undertaken according to a standardised protocol in the following order: (i) height and weight (ii) tests of movement control, (iii) trunk and hip muscle endurance tests, and (iv) one-hour standing task.
