Study Overview
Brief Summary
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.

- Accepts Healthy Volunteers
- Yes
Inclusion Criteria
- •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.

Outcomes
Primary Outcomes
Step Length
Time Frame: The entire duration of each condition, approximately 2 minutes each.
The length of each step taken while walking on a treadmill or overground. It is the anteroposterior distance from one foot to the other at heel strike measured during walking under each condition.
Secondary Outcomes
- Gait speed(The entire duration of each condition, approximately 2 minutes each.)
- Cadence(The entire duration of each condition, approximately 2 minutes each.)
- Movement variability(The entire duration of each condition, approximately 2 minutes each.)
