Brief Summary:
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.

Arm 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

Primary Outcome Measures :
  1. 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).

Secondary Outcome Measures :
  1. 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.
