Primary Outcome Measures:
  • Improvement in Gait [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]

Enrollment: 11
Study Start Date: May 2012
Study Completion Date: December 2013
Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Mobilaser
    Patients will begin by collecting data at home without using the mobilaser. They will then be given the mobilaser to use at home for 6 weeks while they collect data on whether their gait has improved. They will then have to return the Mobilaser to the clinic and collect data at home for 3 days to see if there is a difference.
    Other Names:
    • Laser
    • Walker with laser
Detailed Description:

Can patients walk faster and have less freezing when using the mobilaser then when not using it
