Long periods of intense data entry office work have been linked to increased pain and musculoskeletal disorders. The current study investigated how postural changes mediated by workstation intervention influences the discomfort, postures, and productivity of call center professionals. Thirty-five call center employees were evaluated over two-weeks while performing their job in four different workstation conditions: 1) conventional, 2) sit-stand, 3) conventional with reminder software, and 4) sit-stand with reminder software. The reminder software resulted in reductions in discomfort in the shoulder, hand/wrist, upper back, and lower back. Small increase in the productivity of the workers was also seen for the software reminders. The sit-stand workstation was also effective in reducing discomfort with out decreasing productivity. Periodic breaks that encourage postural changes may be effective in reducing the adverse effects of prolonged static postures commonly found in office work without adversely impact productivity.
