Optimizing Vibrational Therapy to Improve Gait and Balance in Parkinson's Disease
Study Overview
Detailed Description
Enrolled patients with Parkinson's disease, Hoehn and Yahr Stage 2, will be randomized to receive either vibration or no vibration and then will be crossed over to receive the opposite intervention. The study will consist of two treatment periods of two days followed by a washout period of 2 weeks. Each treatment period will consist of four treatments within 2 days, no more than 2 sessions in one day.
Patients will participate in an additional day for screening and another for follow-up (6 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.

- any condition that, in the opinion of the PIs, would compromise participant safety, data integrity, or data interpretation.
- Children under the age of 18
- Prisoners
- Women who are pregnant or may become pregnant during the course of this study since the safety of this device for an unborn child is unknown.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Vibration first then no vibration
A session with PDVibe2 vibration turned on first, followed by (after a 2 week washout period) a session with PDVibe2 vibration turned off.
|
The PDVibe2 is owned by Resonate Forward, LLC and will be loaned to Virginia Commonwealth University (VCU) for this project.
The device is non-invasive, lightweight, untethered, contains a rechargeable battery, and is worn on both feet and ankles.
PDVibe2 delivers vibration when activated by an easy to access switch on the device or by remote.
The internal circuitry has been miniaturized, is encased in a small box, and is attached to the ankle using a soft flexible band.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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.
|
Throughout study completion, from 9 to 34 days.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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.
|
Throughout study completion, between 9 to 34 days.
|
Timed Up and Go (TUG) 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.
|
Throughout study completion, between 9 to 34 days.
|
Berg Balance Scale (BBS)
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.
|
Throughout study completion, between 9 to 34 days.
|
Freezing of Gait Questionnaire (FOG-Q)
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.
|
Throughout study completion, between 9 to 34 days
|
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.
|
Throughout study completion, between 9 to 34 days.
