Parkinson Disease
Conditions
Brief summary
The study will explore if coupling speed and cadence during treadmill training elicit more benefits than controlling speed alone in individuals with Parkinson's disease.
Detailed description
Impaired gait is prevalent and raises the fall risk in people with Parkinson's Disease (PwPD). Gait speed, step length, and cadence are three interrelated components of human gait, as speed is determined by step length and cadence. Auditory cues, such as metronomes, have been shown to aid training for PwPD. The purpose of this study is to examine if controlling cadence and speed improves overground gait parameters in PwPD better than only controlling speed. Two groups of PwPD will participate. Both groups will attend a single treadmill training session. Both groups will complete overground walking trials as a pre-test measurement. One group will receive treadmill training in which cadence, via a metronome, and speed are controlled, while only speed is controlled for the other group. Both groups will complete the same overground walking trials as a post-test measurements. The specific aim of this study is to determine the effects of metronome cues and gait speed versus gait speed alone treadmill training on spatiotemporal gait parameters when walking overground in PwPD.
Interventions
BEHAVIORALAdvanced treadmill walking
Participants will walking on a treadmill for 6 5-minute Blocks. The cadence will be progressively reduced for the first 3 Blocks. Speed will progressively increase during Blocks 4-6 while cadence from Block 3 is maintained.
BEHAVIORALTraditional treadmill walking
Participants will walking on a treadmill for 6 5-minute Blocks. Participants will walk at self-selected cadence during Blocks 1-3. Speed will progressively increase during Blocks 4-6.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in the Gait Speed Determined based on the Time Measured by A Stop Watch and the 10-meter Walking Distance at Post-intervention Assessment Which Is about One Hour Later Than the Baseline Test. | Baseline and post-intervention (about 1 hour following the baseline) | Gait speed will be calculated as the 10-meter walking distance divided by the time used to cover this distance and reported in meters/second. A 10-meter walkway is valid and reliable as an assessment of gait speed. A stop watch is a valid and reliable way to measure the walking time. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in the Step Length Determined by the Vicon Motion Capture System at Post-intervention Assessment Which Is about One Hour Later Than the Baseline Test. | Baseline and post-intervention (about 1 hour following the baseline) | Step length, in meters, will be measured using a 9-camera Vicon motion capture system as the anteroposterior distance between heel markers at initial contact during overground walking. The Vicon motion capture system is valid and reliable to measure human body movement. |
| Change from Baseline in the Step Cadence as Assessed by the Vicon Motion Capture System at Post-intervention Assessment Which Is about One Hour Later Than the Baseline Test. | Baseline and post-intervention (about 1 hour following the baseline) | Step frequency is the number of steps taken during overground walking and reported as steps/min. The Vicon motion capture system is valid and reliable to counter the number of steps taken by a participant within a minute. |
| Change from Baseline in Dynamic Gait Stability Assessed by the Feasible Stability Region Theory at Post-intervention Assessment Which Is about One Hour Later Than the Baseline Test. | Baseline and post-intervention (about 1 hour following the baseline) | Dynamic gait stability is a unitless metric and will be calculated based on the Feasible Stability Region theoretical framework. The Feasible Stability Region framework has been valid and broadly used to quantify dynamic gait stability. |
| Change from Baseline in Ground Reaction Force Assessed by Force Plates at Post-intervention Assessment Which Is about One Hour Later Than the Baseline Test. | Baseline and post-intervention (about 1 hour following the baseline) | Ground reaction force will be be measured by two force plates (AMTI, MA) during overground walking and will be expressed in Newtons. AMTI force plates are valid and reliable to evaluate the ground reaction forces during human walking. |
