Facilitators and barriers to using treadmill workstations under real working conditions: a qualitative study in female office workers.

PURPOSE

Characterize barriers and facilitators to use treadmill workstations in real work sites.

DESIGN

For 6 months, workers tried a sit-stand-walk treadmill workstation at will with expert ergonomic support. Qualitative data were collected monthly.

SETTING

Administrative and academic departments at a higher education institution in Massachusetts, United States.

PARTICIPANTS

Five female administrative office workers.

METHOD

One monthly group interview and one personal interview per participant during 6 months. Emerging topics from previous interviews were used in successive data gatherings. Transcribed data were manually coded according to the predefined topics of usability, comfort, safety, and productivity.

RESULTS

The setup of the work station, communication difficulties while walking (disrespectful, noisy), and peer pressure to maximize use were the main usability barriers. There was no event of falls. Trips were minimized. About comfort, subjects reported it hard to get used to prolonged standing position during the first month. Treadmill speed affected productivity mostly while drawing and working in spreadsheets. Lack of job autonomy was revealed as a generic barrier.

CONCLUSION

In this female group, treadmill workstations had serious design problems for workers with not enough control of their jobs. The early identification and removal of barriers likely needs to be considered when offering these workstations to workers with low job autonomy.
