Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Vibrotactile Coordinated Reset (vCR)

Arm Description

Vibrotactile Coordinated Reset delivers vibratory stimulation to the fingertips of each hand. A specific pattern of vibration to each fingertip is delivered which theoretically disrupts abnormal synchrony in the brain.

Outcomes

Primary Outcome Measures

Movement Disorders Society Unified Parkinson's Disease Rating Scale Part 3 (MDS-UPDRS III change from baseline to 24 months.
This scale measures motor ability within Parkinson's patients. For part 3, the scales minimum values is 0 and max value is 132. Higher scores indicate more impaired motor ability, while lower scores indicate less impaired motor ability. A score of 0 indicates no motor impairment.

Secondary Outcome Measures

Levodopa equivalent daily dose (LEDD) change from baseline to 24 months
LEDD is calculated as a daily sum of levodopa in each Parkinson's medication
Communicative Participation Item Bank (CPIB; Short Form) change from baseline to 24 months.
The CPIB is a questionnaire that measures speech complications. The questionnaire is scored from 0 to 30, with a higher score indicating increased speech difficulties.
Voice Handicap Index (VHI-10) change from baseline to 24 months
This questionnaire can be filled out by patients and assesses the impact that voice problems and limitations have on the individual's overall daily function. Questionnaire is scored from 0 to 40, with a higher score indicating increased speech difficulties.
Freezing of gait questionnaire (FOG) change from baseline to 24 months
The FOGQ assesses Freezing of Gait (FOG) severity unrelated to falls in patients with Parkinson's Disease (PD), FOG frequency, disturbances in gait, and relationship to clinical features conceptually associated with gait and motor aspects (e.g., turning). The FOG is comprised of 6 questions measured on a 0 to 4 scale (where 0 is normal and 4 represents severe abnormalities). The scores are summed together with 0 representing the best possible score and 24 representing the worst possible score.
Vibratory temporal discrimination task (VTDT) change from baseline to 24 months.
The vibratory temporal discrimination task (VTDT) consists of two vibratory bursts, with one burst delivered to the index finger and one burst to the middle finger. This procedure will be performed on the right and left hand separately. The patient is instructed to judge if he/she felt a delay between the two vibratory bursts. The inner stimulus interval (ISI) is RECORDED when the participant indicates that they can feel a difference in time between the two vibrations. The ISI can range from 10ms-110 ms
Movement disorders unified Parkinson's rating scale (MDS-UPDRS) part 1 change from baseline to 24 months.
The MDS-UPDRS part 1 focuses on non-motor symptoms, such as dementia, depression, and psychosis. The total summed score ranges from 0-52 with higher scores indicating increased non-motor impairment.
Movement disorders unified Parkinson's rating scale (MDS-UPDRS) part 2 change from baseline to 24 months.
The MDS-UPDRS part 2 focuses on the patient's ability to perform daily motor activities including dressing, grooming, and using utensils. The total summed score ranges from 0-52 with higher scores indicating increased daily motor impairment.
Movement disorders unified Parkinson's rating scale (MDS-UPDRS) part 4 change from baseline to 24 months.
The MDS-UPDRS 4 focuses on Measures the complications of treatment, e.g. dyskinesias and motor fluctuations. The total summed score ranges from 0-24 with higher scores indicating increased motor complications.
Parkinson's disease cognitive functional rating scale (PD-CFRS) change from baseline to 24 months.
The PD-CFRS capture subjective daily functional cognitive decline among patients with Parkinson's disease over the past 2 weeks. The scale ranges from 0 to 24, with higher scores indicative of cognitive decline.
Parkinson's Disease-Cognitive Rating Scale (PDCRS) change from baseline to 24 months.
The PDCRS is a cognitive test designed to designed to cover the full spectrum of cognitive defects associated with Parkinson's Disease. The total test score ranges from 0 - 134, with higher scores indicating less cognitive impairment.
Parkinsons disease quality of life questionnaire-39 (PDQ-39) change from baseline to 24 months
The PD Quality of Life Questionnaire-39 (PDQ-39) is a self-report questionnaire that examines health related difficulties specific to PD in eight quality of life categories within the last month. Items are grouped into eight scales that are scored by expressing summed item scores as a percentage score ranging between 0 and 100, with higher % indicating more health problems.

5. Study Description

Brief Summary
The purpose of our study is to evaluate Vibrotactile Coordinated Reset stimulation (vCR) and its effects on refractory post surgery PD. VCR will be administered with a device called the vibrotactile axon Glove. vCR is expected to provide patients with a non-invasive alternative to the most widely used treatments such as levodopa and or deep brain stimulation. Patients will be followed for two years.
