The purpose was to determine the daily pattern of use and overall likeability of sit-stand desk over the course of a semester. Participants： A total of 18 subjects （12 standing） completed the 11-week study （week 5-15 of the semester） from January-April, 2016. Methods： Each student in the standing group was given a sit-stand desk to use as they desired. Results： Individual daily standing time ranged from 0-100% of daily attendance time and the daily group average ranged from 2.1-38.4%. Two-thirds of the standing bouts were ≤ 2 min. Perception questionnaire answers were positive for using the desk and their effect on students’ ability to work in class. Conclusions： The results indicate the sit-stand desks were utilized at low levels and for short durations for most participants, but perceptions of desk use remained positive.展开更多
