Travel Behavior of Blind Individuals Before and After Receiving Orientation and Mobility Training (Phase 2: Full-scale Study)
| 项目名称： | Travel Behavior of Blind Individuals Before and After Receiving Orientation and Mobility Training (Phase 2: Full-scale Study) |
| 摘要： | This study devised, tested, and refined a new method for assessing O&M training involving Global Positioning System (GPS) data loggers and accelerometers to collect objective, quantitative, and valid measures of blind individuals� travel behavior, physical activity pre- and post-O&M training. A total of 12 visually impaired travelers were recruited from scheduled recipients of O&M training at the Bosma Enterprises and Leader Dogs for the Blind. Prior to receiving the training, participants� travel and physical activities were recorded using a hip-warn GPS travel recorder and accelerometer devices, and subjectively via an audio-recorded travel diary. Altogether, over 4,000 hours of locational and physical activity data were recorded and analyzed over the 322 days evaluated. The Difficulty with Mobility Questionnaire (DMQ-23) was also administered to measure the participant�s perceived level of difficulty in getting around both before and after the training. The researchers found that the perceived difficulty with mobility among study participants, measured by the aggregate DMQ-23 score, was significantly lower after receiving O&M training indicating enhanced confidence in their mobility skills once they received the training. Small but statistically significant increases in trip distances and durations were found after the training, as measured via more objective measures gleaned from GPS and accelerometer data although no significant gains were observed among study participants in terms of more general physical activity. |
