여성 고령자의 연령과 낙상경험이 시간적ㆍ공간적 보행 변수에 미치는 영향

다국어 초록 (Multilingual Abstract)

This study aims to examine the possible effect of aging and falling interrelationship on??walking and to evaluate gait variables used as indicators for predicting falls by further classifying gait variables, which??were previously classified by the age category (under 70 years old, 70 years old and over) and falling??experiences, with more specified spatio-temporal variables. A total of 144 subjects (72 women: under 70 years old &??72 women: 70 years old and over) were participated in this study, and GAITRite was used as a gait analysis tool.??59 subjects had falling experiences and the rest had not. To examine the interaction effect between falls and??the age on gait, two-way ANOVA analyses were conducted. According to the study results, the correlation??between the age increase and falls showed no effect on senior‘s gait. As the age increased, the temporal gait variables??including the cadence, mean normalized velocity and step time were slower while the double support time??was longer (p <.05). For spatial gait variables, the step length and step/extremity ratio were shorter, the step width (H-H base of support), and the toe direction pointed outward (p<.05). With the falling experience, temporal??gait variables including the cadence, mean normalized velocity and step time were observed to be slower??while the double support time was longer (p<.05). The falling experience did not produce any significant??difference in spatial gait variables such as the step length, step/extremity ratio, the step width(H-H base of support),??and the toe direction. Thus, for elderly women over the age of 65, using temporal gait variables were found to be??more accurate than using spatial gait variables in analyzing senior‘s gait variables or applying variables to predict??falls in terms of using the falling experience as an indicator.
