简要总结
This is a cross-sectional and prospective cohort study using a biopsychosocial approach to investigate office workers at risk of standing-induced musculoskeletal pain. The purpose of this study is to determine which factors are associated with developing or worsening of musculoskeletal pain (changes in the Visual Analogue Scale from baseline) during a 60 minute standing paradigm.
详细描述
Background/rationale
There is growing national and international evidence for the negative health impact of sedentary behaviour at work. A strategy being increasingly adopted to reduce prolonged sitting is to spend some of the work day in standing. However, for some adults, prolonged standing is associated with the development of musculoskeletal pain. We are investigating which factors are associated with developing of musculoskeletal pain during standing when using a height-adjustable desk. Previous studies have used an induced-pain paradigm to understand risk factors for developing musculoskeletal pain during a prolonged standing task that simulates the work environment (standing paradigm). Identifying those office workers who are at risk of developing musculoskeletal pain during standing will provide information to guide health professionals and individuals in making decisions about optimal workstation design.
Objectives and hypothesis
- Cross-sectional study: Identify which factors are associated (demographic, physical, psychological and work-related factors) with standing-induced musculoskeletal pain in office workers during a standing paradigm.
- Prospective cohort study: Identify incidence/prevalence and risk factors of low back pain, and disability associated with low back pain in office workers in a 1-year prospective cohort.

结局指标
主要结局
Standing Tolerance Test (STT)
时间窗: Baseline
The Standing Tolerance Test consists of participants standing for 1-hour while performing computer tasks using a workstation table.They are required to stand in a confined working area marked on the ground (60x122 cm). During the 1-h period, participants are instructed to adopt a comfortable position that they would normally use if they are to stand for a prolonged period of time. The participant are not allowed to lean on the workstation in any way. The working surface for each participant is adjusted to a height of 5 cm below elbow height. Participants rate their musculoskeletal symptoms intensity on a scale from 0 to 100 mm visual analogue scale (VAS) prior to the start of, every 15 minutes during, and at the end of the 1-h standing period. Based on their VAS rating for spine, lower and upper limb, they are classified either as a Pain Developers (PDs) if they report a change in VAS of 1 or more from baseline on 0-100 scale (whatever baseline is) or a Non-Pain Developers (NPDs).
