One hundred women patients at a midwestern university health center were randomly assigned to a control or experimental group to measure statistically comfort levels of new foot supports vs. traditional metal stirrups during pelvic examinations. Written comments were also obtained. Analyses using the t test demonstrated a significant positive change in attitude in the experimental group.
