Vibrotactile Stimulation in Parkinson's Disease

Brief Summary:
The purpose of this study is to examine the possibility of a new, non-invasive, non-drug treatment for Parkinson's disease. The treatment involves gentle vibratory stimulation delivered to the fingertips (called 'vibrotactile stimulation'). Along with the treatment, participants will also undergo kinematic testing.

Condition or disease Intervention/treatment Phase
Parkinson's Disease Device: Vibrotactile Stimulation Not Applicable

Detailed Description:
Patient will be phone screened and/or have a physical and neurological examination to determine if it is appropriate for them to participate in this study. This testing includes the Unified Parkinson's Disease Rating Scale, Part III (UPDRS III). Research assistants will explain the study and obtain informed consent. There will be three consecutive days of testing, as well as 2 follow up visits at 1 and 4 weeks. Visits include the following: Patients will have sensors put on their hands, feet, and chest. These sensors measure their movement while they perform kinematic tasks such as forward walking, wrist movements, and the UPDRS III. Patients will also be given vibrotactile stimulation for a total of 4 hours throughout the day. During this time, patients will be provided with books/movies as entertainment, and they may move around freely. Patients will also be asked to complete several questionnaires throughout the visits about their Parkinson's symptoms.

Arm Intervention/treatment
Experimental: Vibrotactile Stimulation Treatment
All patients will receive the vibrotactile stimulation treatment. No deception will be used.
Device: Vibrotactile Stimulation
The tactile stimulator is being tested for an off-label use as treatment for Parkinson's disease. There are nodes embedded into the fingertips of gloves that gently vibrate in an alternating pattern. The sensation is similar to the feeling of a phone vibrating. This is a non-significant risk device.

Primary Outcome Measures :
  1. Number of Patients Reporting Any Adverse Effects [ Time Frame: 1 Month ]
    Questionnaire asks patients to record any adverse effects they experienced.

Secondary Outcome Measures :
  1. Unified Parkinson's Disease Rating Scale, Part III [ Time Frame: 1 Month ]
    We used the motor portion of the Unified Parkinson's disease Rating Scale (UPDRS) and excluded rigidity and speech from the assessment. Overall range of the score for the motor portion (excluding rigidity and speech) range from 0 to 108, where 0= best possible outcome and 108= worst possible outcome.

  2. Root Mean Square Velocity [ Time Frame: 1 Month ]
    Using gyroscopes to track patient movement testing, root mean square velocity (Vrms) of of the wrist during repetitive wrist flexion extension task was obtained.

  3. Gait Asymmetry [ Time Frame: 1 Month ]
    Using data collected from inertial measurement unit (IMU) sensors on subject, we were able to measure gait asymmetry. For each subject, the swing time (SW) was calculated and averaged across strides for the left and right legs (SWL and SWR). We obtained gait asymmetry using the following: 100 x /ln(SWR/SWL)/. 0 marks perfect symmetry and greater values higher asymmetry. There is no maximum limit.
