NCT03845803

Brief Summary

This is a one year observational field study investigating changes in sedentary behaviour and the prevalence of musculoskeletal disorders of office workers induced by sit/stand workstations. All employees of an Austrian bank headquarter (approx. 1200 people) will be newly equipped with electric sit/stand workstations by their company in February and March 2019. The main outcomes will be occupational sitting and standing time as well as the occurence and intensity of neck and back pain.

Outcome Measures

Primary Outcomes (6)

  • Changes in occupational sitting time

    Subjects will report the amount of occupational sitting time by means of the OSPAQ. The amount of working hours in the last 7 days will be multiplied by the percentage of time spent sitting at work in the last 7 days to get the overall amount of minutes sitting at work per week.

    baseline, 12 months

  • Changes in occupational standing time

    Subjects will report the amount of occupational standing time by means of the OSPAQ. The amount of working hours in the last 7 days will be multiplied by the percentage of time spent standing at work in the last 7 days to get the overall amount of minutes standing at work per week.

    baseline, 12 months

  • Changes in the one year prevalence of neck pain

    Subjects will report the one year prevalence of neck pain by means of the Nordic Musculoskeletal Questionnaire.

    baseline, 12 months

  • Changes in the one year prevalence of back pain

    Subjects will report the one year prevalence of back pain by means of the Nordic Musculoskeletal Questionnaire.

    baseline, 12 months

  • Changes in the average one year neck pain intensity (VAS)

    Subjects will report the one year neck pain intensity by means of a Visual Analogue Scale (VAS). The VAS used for this study ranges from 0 (no pain) to 100 (heavy pain) points.

    baseline, 12 months

  • Changes in the average one year back pain intensity (VAS)

    Subjects will report the one year neck pain intensity by means of a Visual Analogue Scale (VAS). The VAS used for this study ranges from 0 (no pain) to 100 (heavy pain) points.

    baseline, 12 months

Secondary Outcomes (12)

  • Changes in occupational sitting time

    baseline, 3 months, 6 months

  • Changes in occupational standing time

    baseline, 3 months, 6 months

  • Changes in the average one year prevalence of shoulder pain

    baseline, 12 months

  • Changes in the average one year shoulder pain intensity (VAS)

    baseline, 12 months

  • Changes in the average one week prevalence of neck pain

    baseline, 3 months, 6 months, 12 months

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

People of all genders, between 18 and 65 years of age, working in an Austrian bank headquarter, who are affected by their company´s plans to replace all office workstation desks (non-adjustable) by electric height-adjustable sit/stand workstations with desk-height memory function in March 2019.

You may qualify if:

  • All office workers from a bank headquarter who are affected by the office furniture change (replacement of traditional sitting work desks by sit/stand workstations)
  • People with sufficient German language skills (able to understand the questions of the questionnaires)
  • People who gave their written consent to participate prior to involvement in the study

You may not qualify if:

  • People without an employment at the examined bank headquarter
  • People who are not able to use sit/stand workstations due to physical impairments
  • People on educational or maternity leave
