The purpose of this study is to determine how using auditory cues of a metronome and music at
various frequencies impacts the gait mechanics in people with Parkinson's disease when
walking over ground and on a treadmill.
The investigators will enroll a total of 40 participants: 30 subjects with a diagnosis of
Parkinson's disease (10 in Stage 1, 10 in Stage 2, and 10 in Stage 3) and 10 unimpaired
subjects.
Participants will complete 7 different treadmill walking conditions and overground walking
conditions while the investigators measure step length, cadence, gait speed, and variability
of movement.

Participants will complete 7 different treadmill walking conditions and overground walking
conditions while the investigators measure step length, cadence, gait speed, and variability
of movement.
10 unimpaired controls and 30 subjects with Parkinson's Disease (described in detail below
- see inclusion/exclusion criteria). The 30 subjects with Parkinson's Disease will be
assigned into 3 groups (10 with H&Y Stage 1, 10 with H&Y Stage 2, and 10 with H&Y Stage 3).
Inclusion Criteria:
- Individuals with a diagnosis of Parkinson's Disease (made by movement disorders
specialist) will be included in this study. Additional inclusion criteria include:
self-reported ability to walk >10 m overground as well as walk on a treadmill for a
total of 14 minutes with rest breaks as needed, and be classified as Stage 1, 2, or 3
on the Hoehn and Yahr Scale since these stages have the most independence with
mobility (Goetz et. al, 2004).
Exclusion Criteria:
- Exclusion criteria include Hoehn and Yahr Stage 4 and 5, uncontrolled
cardiorespiratory/metabolic disease (e.g., cardiac arrhythmia, uncontrolled
hypertension or diabetes, orthostatic hypertension, chronic emphysema), or other
neurological or orthopedic disorders that may affect walking. The investigators will
also exclude participants with severe communication impairments, which could impede
understanding of the purpose or procedures of the study or an inability to comply with
experimental procedures.
