Brief Summary
Treatment resistant motor features, such as postural instability and freezing of gait are common in people with Parkinson's disease and major contributors to morbidity and mortality. This project will use sleep studies, quantitative motor assessments and magnetic resonance imaging to examine the relationship between abnormally increased muscle activity during rapid eye movement sleep and the development and progression of treatment-resistant postural instability and gait disturbances. Specifically, the investigators will test the hypothesis that anticipatory postural adjustments (weight and pressure shifts) during gait initiation are significantly reduced in people with Parkinson's disease who have abnormally elevated muscle activity during rapid eye movement (REM) sleep compared to individuals will Parkinson's disease whose REM sleep muscle activity is normal. In addition, the investigators will test the hypothesis that the level of RSWA at baseline is predictive of measures of motor decline (postural stability and gait) and alterations in the structure and function of locomotor brainstem networks. Since sleep disorders can emerge years before a diagnosis of Parkinson's disease, establishment of a link between sleep and treatment-resistant posture and gait disorders will help identify individuals at risk of developing these disabling motor features of disease.

Outcome Measures
Primary Outcomes (2)
Magnitude of the center of pressure shift during gait initiation.
The magnitude of the center of pressure shift during gait initiation is calculated as the displacement of the center of pressure signal from quiet standing (baseline) to the peak lateral and posterior excursion during the anticipatory postural adjustment phase of gait initiation.
Measured at baseline (time 0).
Correlation between measures of REM sleep without atonia (RSWA) at baseline and change in the magnitude of the center of pressure shift during gait initiation over the course of 3 years.
A linear correlation analysis will be conducted between measures of RSWA at baseline versus the change in shift of the center of pressure during gait initiation between baseline and year 3.
Change in magnitude over the course of 3 years
Study Arms (2)
Parkinson's Disease participants
People with early Parkinson's disease with mild-to-moderate severity of disease.
Control participants
Volunteers who are age (+/- 3 years) and sex matched to the participants with Parkinson's disease
Interventions
Participants will be asked to visit the University for 3 baseline visits which include a screening visit \& sleep study, movement tests and magnetic resonance imaging (MRI) scans. Three years later the participant will be asked to repeat the same visits.
