Brief Summary:
Balance and gait impairment increases the risk of falls and contributes to a reduced quality of life and shorter survival in Parkinson disease (PD) and atypical Parkinsonism patients. In preliminary case studies, electrical epidural spinal cord stimulation (SCS) has been shown to significantly improve gait, postural instability, rigidity, and tremor. Controlled studies for optimizing which stimulation settings produce the best clinical response for mobility and gait, and achieving these results chronically are all significant unmet needs. Using quantitative laboratory and mobile technologies to test a range of stimulation settings, this research study aims to determine which SCS parameters or combination of parameters is best suited to effectively alleviate disabling symptoms experienced by each patient.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Tailored SCS programming [ Time Frame: 3 weeks ]
    Participants following SCS implantation will undergo 3 programming visits. 9 SCS programs will be tested in a repeated fashion on separate days and at different times of the day (morning vs afternoon). The SCS setting(s) to produce the best motor (gait) response will be used by the participant in-home. SCS device will not be used during this time period.

  2. Changes in spatiotemporal gait measures using objective gait analysis [ Time Frame: 12 months ]
    Spatiotemporal gait parameters known to be affected in parkinsonian syndromes will be analyzed over a 12 month period using gait analysis software. Best SCS setting tailored to each participant's gait symptoms will be assessed at 3-, 6- and 12-months time-points.


Secondary Outcome Measures :
  1. Changes in UPDRS-III scores [ Time Frame: 12 months ]
    UPDRS-III assessment will be assessed pre-surgery and post-surgery at 3-, 6- and 12-month time-points while participants are OFF/ON-dopaminergic medication and OFF/ON SCS.

  2. Changes in NFOG-Q scores [ Time Frame: 12 months ]
    NFOG-Q scores will be assessed pre-surgery and post-surgery at 3-, 6- and 12-month time-points.

  3. Changes in PDQ-39 scores [ Time Frame: 12 months ]
    PDQ-39 scores will be assessed pre-surgery and post-surgery at 3-, 6- and 12-month time-points.

  4. Changes in ABC scores [ Time Frame: 12 months ]
    ABC scores will be assessed pre-surgery and post-surgery at 3-, 6- and 12-month time-points.

  5. Changes in QoL scores [ Time Frame: 12 months ]
    QoL scores will be assessed pre-surgery and post-surgery at 3-, 6- and 12-month time-points.

  6. DaTscan imaging [ Time Frame: 12-months ]
    Asymmetry and specific binding ratios (SBRs) of the striatal regions of dopamine transporter from I-123 FP-CIT SPECT images will be quantitatively analyzed from pre-surgery and 12-months of SCS use.

  7. Proprioception testing [ Time Frame: 12-months ]
    KINARM and lower leg KINARM type of robot collects reaction time, speed, force, accuracy and trajectory using a robotic object hitting game to assess cognitive and motor skills to be conducted pre-surgery, and post-SCS at 3-, 6- and 12-months
