Objective: The aim of the study was to determine whether chronic low back pain (LBP) might be attenuated through the introduction of a sit-stand workstation (SSW) in office employees.

Methods: Participants were randomized to receive a SSW at the beginning or at the end of a 3-month study period. Participants responded to a short survey at the end of each workday and a comprehensive survey at weeks 1, 6, and 12. Surveys consisted of a modified brief pain inventory and the Roland Morris Disability Questionnaire.

Results: Forty-six university employees with self-reported chronic LBP were enrolled. Participants who were given access to a SSW reported a significant reduction in current (P = 0.02) and worst (P = 0.04) LBP over time.

Conclusions: Our findings support the hypothesis that chronic LBP might be improved by the introduction of a SSW in an office environment.
