Background: The purpose of this study was to investigate the relationship between the changes to postural
sway velocity and trunk repositioning errors and the frequency of falls in stroke patients.
Methods: Fifty-five stroke patients, divided into three groups (no falls group: 20, one fall group: 19, repeated
falls group: 16), stood quietly with eyes open and closed on a force platform while postural sway velocity was
quantified by the center of pressure measures. Trunk repositioning errors were measured in standing while the
subjects performed forward flexion movements.
Results: We found a significant difference between the groups for postural sway velocity in medial-lateral and
anterior-posterior directions with eyes open and closed (P<0.05). With the eyes closed, there were significant
differences between the three groups in the postural sway velocity (P<0.05) and the trunk repositioning errors
changed significantly (P<0.05).
Conclusions: Our results demonstrate that the increase in falls may increase visual dependence for postural
control velocity and trunk repositioning errors. These results may be useful in balance training to prevent falls
in stroke survivors.
