Background: The purpose of the study was to investigate the effects of visual feedback training using force plate on balance and balance confidence in patients with stroke.
Methods: The subjects of the study were twenty patients with stroke who were randomly assigned to the visual feedback training group (VFTG,n=10), unstable surface training group(USTG,n=10). The VFTG and USTG performed the conventional exercise therapy twice a week for 30 minutes during 4 weeks. In addition the subjects in VFTG performed the visual feedback training and the subjects in USTG performed the training on the unstable surface three times a week for 30 minutes during the whole training period respectively.
The static and dynamic balance parameters (C90 area in sway line for postural sway of center of pressure, Trace length in sway line for postural sway of center of pressure, Sway range in antero-posterior direction for limit of stability, Sway range in medio-lateral direction for limit of stability) were measured by BT-4 and balance confidence was measured Korean specific-activities balance confidence scale. Outcome measurements were taken before and after the 4 weeks of training. For data analysis, t-test was used to compare the two groups. The results of this study were as follows.
Results: VFTG was significantly improved all of the static and dynamic balance parameter and the Korean activities-specific balance confidence (p<0.05), but USTG was significantly improved dynamic balance parameter and the Korean activities-specific balance confidence (p<0.05) only. Also,VFTG showed significantly improvements on the static and dynamic balance parameter and the Korean activities-specific balance confidence compared with USTG (p<0.05).
Interpretation: Based on these results, it was found that visual feedback training was effective for hemiplegic patients with stroke on balance and balance confidence. Thus, I suggest that visual feedback training will be effective intervention to prevent the falls in patients with stroke.
