A quasi-experimental design study was adopted with each workstation evaluated for a 1-month period (2-week break-in period and a 2-week observation period) (see Figure 1 for timeline of conditions). Complete demographic and anthropometric data can be found in Table 1. The participation rate was 76%, with one worker being lost to follow-up due to leaving the place of employment (the partial data were not analyzed in the results). All participants had worked at the facility for at least 1 year. The participants were full-time (18 employees) and part-time (19 employees) employees at the call center. The gender mix was representative of the gender ratio in the call center. Thirty-seven (29 females and 8 males) call center employees were recruited from a local drug and poison information center that is open 24 hours a day, 7 days a week, and handles regional emergency calls that deal with drug overdose and poison ingestion. Four different office workstation conditions were evaluated including a conventional workstation, sit-stand workstation, conventional workstation with reminders to take breaks, and sit-stand workstation with reminders to switch table heights and adopt postural changes. The current study investigated whether interventions aimed at postural change could encour- age adoption of routine dynamic movement of the body, resulting in decreasing musculoskeletal discomfort and increased productivity. However, two additional reviews (Hoe, Urquhart, Kelsall, & Sim, 2012 Kennedy et al., 2010) reported limited positive results for rest breaks being effective in control- ling musculoskeletal disorders of the neck and shoulder for computer work.
#Desk break reminder software
Bernaards, Ariëns, Simons, Knol, and Hildebrandt (2008) reported that reminder software was effective in encouraging the use of breaks. (2012) reported that the few studies investigating rest breaks as an intervention found positive results-decreased pain and static awkward postures.
Furthermore, the effectiveness of stretching is compounded by compliance issues and appropriateness of the stretching for specific work conditions. The results indicated that the breaks, but not stretching, had an impact on the discomfort of the workers, possibly due to noncompliance of stretching. A follow-up study from this group evaluated routine breaks with stretching (Galinsky et al., 2007). A study conducted by Galinsky, Swanson, Sauter, Hurrell, and Schleifer (2000) showed that frequent (5 min break/hour) breaks significantly decreased discomfort for data entry workers as compared to a conventional break schedule (two 15 min breaks/day). Another type of postural change intervention is to remind workers to take more routine breaks. workstations has shown low levels of usage compliance-work- ers stop adjusting the tables after a few weeks, indicating any benefits could be lost over time (Wilks, Mortimer, & Nylen, 2006).
