| Summary: | 碩士 === 國立臺灣師範大學 === 體育學系在職進修碩士班 === 91 === The purpose of this study was to find the suitable slopes for blind students by comparing the gait effects of blind students and normal students walking down the ramps with different slopes. By using the digital camera, the gait motion of the participants walking down the ramps was caught. Computer software of Ariel Performance Analysis System was used to digitize the gait motion and acquire the information of temporal-spatial parameters. The selected variables were analyzed by using the ANOVA program of SPSS to investigate the differences. Subjects were chosen as two groups: 1.Sixteen blind students came from Nation Taichung School for Visually Impaired, mean age 18.60±1.92 yr, mean ht.162.25±11.25 cm, mean wt.67.36±15.19 kg, the mean leg length 84.50±6.54 cm. 2.Sixteen normal students came from Nation Chin-shui Senior High School, mean age 16.98±0.84 yr, mean ht.166.75±3.94 cm, mean wt.56.88±7.25 kg, the mean leg length 89.19±7.94 cm. Different slopes of the ramps ranged(height and length) as 1/12, 1/10, 1/8, 1/6,1/5 and 0 were used in the experiment. The results were listed as follows:
1. The walking gaits of blind students were greatly different from normal students’, especially in stride length, velocity, and the rate of stride length/leg length. The major reason was that the stride length in blind students was significantly shorter.
2. The slopes designed in this experiment had few effects on normal students’ gait walking down the ramps. However they had great effect on blind students’ gait. As the ramps rose upward, especially to 1/10(height/ length), the gait of blind students showed apparent changes.
Therefore, for the sake of blind students’ security and stability, the ramp slopes designed, especially for blind students, should be reduced less than 1/10.
