Abstract |
PURPOSE The purpose of the study was to investigate postural adjustments on effects of fear of falling and directional change during Gait Initiation(GI). METHODS Three groups are formed with fear of falling and the senior fitness test results, and they performed with gait in a forward direction and to the right direction(90°). In order to get the data, ten cameras, makers, and EMG were used. Two way ANOVA was used to compare kinematic, spatio·temporal parameters and EMG data. RESULTS The HO-TO duration in a GI to the right direction was shorter than in a straight ahead GI at left foot swing. The step width of left foot in TO-HS was significantly larger in the GI to the right direction. The medial·lateral of center of mass velocity in the GI to the right direction was slower than in a straight ahead GI. CONCLUSIONS There were significant differences of kinematic parameters in the straight ahead GI and the GI to the right direction, but fear of falling did not affect in the walking type. Further research would be suggested investigating the change of weight load and center of mass for elders with fear of falling during GI. |
