Access to a Sit-stand Computer Workstation and Back Pain

October 6, 2017 updated by: Kathleen Horst, Stanford University

Evaluating Change in Back Pain From Access to a Sit-stand Workstation

The purpose of the study is to evaluate the changes in back pain from access to a sit-stand workstation. Other muscle and joint pain and/or discomfort will also be evaluated. We hypothesize that access to a sit-stand workstation will allow one to experience postural variation and reduce back pain.

Intervention / Treatment
No Intervention: Control
Did not receive an intervention during the active portion of the study (i.e. 12 weeks). After the active portion of the study, this group was given a sit-stand computer workstation.
Experimental: Sit-stand computer workstation
Given a sit-stand computer workstation to use at their place of work
Other: Sit-stand computer workstation
A sit-stand computer workstation allows one to sit or stand throughout the day while maintaining continued use of one's computer.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Back Pain
Time Frame: Baseline (Week 1) and Follow-Up (Week 18)
The Roland-Morris Disability Questionnaire is designed to assess self-rated physical disability caused by low back pain. The patient is asked to agree or disagree with 24 different statements related to their back pain. The end score is the sum of the agreed statements. The score ranges from 0 (no disability) to 24 (maximum disability).
Baseline (Week 1) and Follow-Up (Week 18)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Pain in Other Body Parts
Time Frame: At the conclusion of each work day for 12 weeks and 8 weeks later
The Brief Pain Inventory (BPI) allows patients to rate the severity of their pain and the degree to which their pain interferes with common dimensions of feeling and function. This data was not analyzed due to the focus of the project on lower back pain.
At the conclusion of each work day for 12 weeks and 8 weeks later
