研究概览
简要总结
The purpose of this study is to determine whether a training program in the use of ambulatory assistive devices (such as canes, walkers, etc) can reduce falls and increase functional mobility and neural connectivity in people with Multiple Sclerosis.
详细描述
40 people with Multiple Sclerosis, who routinely use ambulatory assistive devices and have fallen at least once in the past year, will be randomized into two groups. One group will receive a 6-week training program in the use of their assistive device; the other group will be wait-listed, and may choose to receive the training after their participation in the study is completed. All participants will receive mobility assessments at baseline, 6-8 weeks later, and 3 months after that. All participants will record their falls on falls calendars. Participants in the training group will receive MRI scans to assess neural connectivity at baseline and after completion of the training program.
The purpose of the study is to determine whether participation in the training program reduces falls and increases functional mobility when compared to the wait-listed group, and also to determine whether any change in neural connectivity, as assessed by MRI scans, is seen in those who participate in the training.

研究组 & 干预措施
Training group
Subjects randomized to this group will receive a 6 week Assistive Device Training program in the use of their assistive device. They will have mobility assessments taken at baseline, after the training program has been completed, and 3 months later. During this time, their falls will be recorded monthly using prospective falls calendars. Members of this group will also receive MRI scans at baseline and after the completion of the training program.
干预措施: Assistive Device Training (Behavioral)
Wait-list control
Subjects in this group will participate in the same mobility assessments and completion of the falls calendars, but will receive no intervention during this time. These subjects will have the opportunity to receive the training sessions when all assessment visits have been completed. These subjects will not receive MRI scans.
