Using real-time visual feedback to improve posture at computer workstations.

The purpose of the current study was to examine the effects of a multicomponent intervention that included
discrimination training, real-time visual feedback, and self-monitoring on postural behavior at a computer
workstation in a simulated office environment. Using a nonconcurrent multiple baseline design across 8
participants, the study assessed the effects of the intervention across three postural variables. Following
an information phase, the intervention started for the lowest stable postural variable. The intervention led
to substantial improvements in safety behavior for most targeted postural variables. A reversal to the
information phase for 2 participants did not lead to decreases in safety. Postures self-monitored with high
accuracy improved to a greater degree than postures self-monitored with low accuracy.
