Brief Summary:
The purpose of this research study is to determine optimum dose of vibration delivered by an experimental device called PDVibe2 required to treat freezing of gait in persons with Parkinson's disease (PD). The PDVibe2 was developed by Resonate Forward, LLC (RF). This PDVibe2 was designed to administer vibration therapy to the wearer to improve gait and balance in persons with PD while wearing the device.

Condition or disease Intervention/treatment Phase
Parkinson Disease Device: PDVibe2 Not Applicable

Detailed Description:
Participation will require up to 8 treatment sessions within 5 days (no more than 2 sessions in one day) plus an additional day for screening and another for follow-up (7 days total). All visits will occur at the Virginia Commonwealth University Parkinson's Movement and Disorders Center in Richmond, VA. Participants will be asked to walk for a brief period of time while wearing the PDVibe2. The PDVibe2 will provide vibration therapy and study staff will measure the number of "freezes" before, during and after therapy. Participants will be asked to provide feedback on the device, the therapy session and how they are feeling.

Primary Outcome Measures :
  1. Functional Ambulation Profile (FAP) Score [ Time Frame: Throughout study completion, from 9 to 34 days. ]
    The FAP score is the gold standard for spatiotemporal gait parameter analysis. For this study, it will be calculated by participants walking on the Zeno walkway, which will measure the patient's physical measurements, step length, step time and degree of symmetry.Step length, step time, degree of symmetry, dynamic base of support and the use of ambulatory aids are factored into the score. The Zeno instrumented walkway (PKMAS) is a 20-foot computerized instrumented walkway containing sensor pads.


Secondary Outcome Measures :
  1. Movement Disorder Society Unified Parkinson Disease Rating Scale (MDS-UPDRS) Part III [ Time Frame: Throughout study completion, between 9 to 34 days. ]
    The "Movement Disorder Society Unified Parkinson Disease Rating Scale" (MDS-UPDRS), parts II-IV will be used to assess the total burden of motor Parkinson Disease (PD) symptoms and impact on activities of daily living. All parts use scale of 0 (no problem) - 4 (severe problems) lower scores are better. Part II: 13 items about Activities of Daily Living, score range 0-52. Part III: 18 items PD motor signs, score range is 0-72, Part IV: 6 items, assesses dyskinesia (excessive motion) and motor fluctuations (medication is working or not), range is 0-24. Parts II-IV total scores will be summed and used to describe the participants, total score range 0-148. Part III, only, will be repeated during vibration and post vibration data collection times and will take 5 minutes to complete. This outcome measure will be used to report a change in PD motor symptoms from baseline, to vibration on, and at follow up two after treatment is completed.

  2. Timed Up and Go Test [ Time Frame: Throughout study completion, between 9 to 34 days. ]
    This test is a one item performance test. The participant starts by sitting in a chair, then stand up, walk 3 meters, turn around, walk back, and sit down. Participants are timed in seconds. TUG is used to identify/screen elderly individuals who are prone to falls. Lower numbers are better.

  3. Berg Balance Scale [ Time Frame: Throughout study completion, between 9 to 34 days. ]
    The BBS assesses balance via performing 14 functional activities. Each item is scored along a 5-point scale, ranging from 0 to 4. Zero indicates the lowest level of function and 4 the highest level of function. The total score is a summation of all items and ranges from 0 to 56. Higher scores indicate less risk of falls. A cutoff score of 45 has been traditionally identified as a useful cutoff to predict falls in those who scored below the cutoff score.

  4. Freezing of Gait Questionnaire [ Time Frame: Throughout study completion, between 9 to 34 days ]
    The FOG-Q is a six-item questionnaire that uses a 5-point scale that ranges from 0 = absence of symptoms to 4 = most severe stage. The total score ranges from 0 to 24; higher scores correspond to more severe FOG.

  5. Parkinson's Disease Questionnaire - 39 [ Time Frame: Throughout study completion, between 9 to 34 days. ]
    This is a 39 item self-report questionnaire assesses how often patients experience difficulties across the 8 quality of life dimensions of functioning and well-being. A five-point ordinal scoring system ranges from 0 Never to 5 = Always or cannot do at all. Scores are calculated for each dimension (sum of items divided by number of items /100; total score is summative

  6. Fall Efficacy Scale - International [ Time Frame: Throughout study completion, between 9 to 34 days. ]
    This survey includes 16 items assessing fear of falling in different scenarios, in a community dwelling older population. Individuals are instructed to rate each activity on a four-point Likert scale, depending on how they concerned that they may fall when performing certain activities. Items are scored from 1 = Not at all concerned to 4 = very concerned. The total score ranges from 16 - 64. The higher the score the greater the fear of falling.
