Brief Summary
The purpose of this study is to gather data to see if the Laser Cane and/or U-Step Walker with laser accessory is more effective in aiding with gait freezing than a regular cane/U-Step Walker in patients who have idiopathic Parkinson's disease.

Outcome Measures
Primary Outcomes (1)
Mean Change From Baseline (Visit 1 Until Visit 2) to Endpoint (After Visit 2 Until Visit 3) in the Freezing of Gait Questionnaire Score.
The FOGQ has a minimum of 0 and max of 4 for each question, with 4 representing more severe freezing of gait. There are 6 questions, so the total score ranges from 0 to 24. It was pre-specified that all 26 subjects were treated as a single group with respect to the primary outcome measure regardless of whether or not they had a 1 month or 2 month baseline period.
2-3 months
Secondary Outcomes (3)
Mean Change in Time to Perform the Timed Gait Test With vs Without the Laser Feature
2-3 months
Mean Change in Number of Falls Without Versus With the Laserlight Visual Cue.
2-3 months
Percentage Change in Falls
1 to 2 months
Study Arms (2)
1 mo baseline
ACTIVE COMPARATOR1 mo baseline before visual cue: Cane or walker, no laserlight visual cue x 1 mo; + laserlight visual cue for 2nd mo
2 month baseline
NO INTERVENTIONCane or walker, no laserlight visual cue x 2 mo, + laserlight visual cue for 3rd mo
Interventions
Laser Cane with Laser Accessory and/or U-Step Walker with Laser Accessory
Eligibility Criteria
You may qualify if:
- Subjects or a designated proxy have given informed consent
- Subject has been diagnosed with idiopathic Parkinson's disease
- Subject is ambulatory. If a wheelchair is used part-time, it must be used for less than 50% of the time
- Positive assessment for Questionnaire Used to Identify Freezing of Gait in PD Patients at subject's best "on"
You may not qualify if:
- Presence of atypical features suggestive of MSA, PSP, ataxia, unexplained or prominent pyramidal signs, and/or autonomic dysfunction
- Subjects who are non-ambulatory more than 50% of the time
- Subjects who have had a history of syncope in the 6 months prior to screening
- Subjects with moderate or advanced dementia
