Estimated Enrollment: 30
Study Start Date: October 2008
Estimated Study Completion Date: October 2009
Estimated Primary Completion Date: October 2009 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Patients with Parkinson's disease prone to freezing
Device: Auditory cue
When device recognizes automatically freezing episode it will generate auditory cue

Detailed Description:

The subjects will walk with an accelerometer. The acceleration traces will be online analyzed, and if freezing episode is recognized, an auditory cue will be heard.
