Targeted Motor Learning to Improve Gait for Individuals With Parkinson Disease

June 23, 2026 updated by: University of North Carolina, Chapel Hill
The purpose of this research study is to determine how training to step with a metronome on both a treadmill, as well as overground, will influence the way that people with Parkinson disease walk. Using metronomes is commonly used in clinics, but the investigators will be using a combination of slow and fast frequencies to alter the way that people walk. The use of a slower frequency metronome on the treadmill is intended to help participants take larger steps. The use of a faster frequency metronome while walking overground is intended to help participants take faster steps.This will take place over 12 training sessions. Each session will be about an hour. It will include some walking tests and pictures of the brain (using MRI) before and after training.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Six minute walk test (6MWT) at the 3 month follow up visit
Time Frame: Baseline, 3 month follow-up
The 6-minute walk test provides a more objective quantitative measure of mobility, functional performance, and symptom control. It measures the distance an individual can walk over a total of six minutes on a hard, flat surface. The individual can self-pace and rest as needed as they walk back and forth along a marked course. The participant can use an assistive walking device they normally use, such as a cane. The minimum clinically important difference in 6-minute walk distance is approximately 30 meters, a difference that is associated with mortality. A higher change score represents a greater improvement in walking function and a better outcome.
Baseline, 3 month follow-up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Six minute walk test (6MWT) after 4 weeks of training
Time Frame: baseline, 4 weeks
The 6-minute walk test provides a more objective quantitative measure of mobility, functional performance, and symptom control. It measures the distance an individual can walk over a total of six minutes on a hard, flat surface. The individual can self-pace and rest as needed as they walk back and forth along a marked course. The participant can use an assistive walking device they normally use, such as a cane. The minimum clinically important difference in 6-minute walk distance is approximately 30 meters, a difference that is associated with mortality. A higher change score represents a greater improvement in walking function and a better outcome.
baseline, 4 weeks
Walking stride length
Time Frame: up to 3 month follow-up
The walking stride length represents the average stride length (distance between where one foot strikes the ground to the location that the same foot strikes the ground to complete the stride). The distance is measured from walking over a pressure mat during the 6MWT. This measurement will be completed at baseline (prior to training), after 4 weeks of training, and again for a 3 month follow-up. A larger value represents longer steps, and a better outcome.
up to 3 month follow-up
Walking Cadence
Time Frame: up to 3 month follow-up
Walking cadence is the frequency of steps per minute (inverse of step time). The average cadence is measured from passes over a pressure mat during the 6MWT, and will be completed at baseline (prior to training), after 4 weeks of training, and again for a 3 month follow-up.
up to 3 month follow-up
Gait interruption index
Time Frame: up to 3 month follow-up
The Gait Interruption Index represents the number of 'freezes' observed, divided by the number of 'freeze opportunities' (i.e., turns, times stepping on/off pressure mat) completed during the 6MWT. A higher number represents greater impairment in Freezing of Gait. This measurement will be completed at baseline (prior to training), after 4 weeks of training, and again for a 3 month follow-up.
up to 3 month follow-up
Mini BESTest (Balance Evaluation Systems Test) score
Time Frame: up to 3 month follow-up
The mini-BESTest is a 14-item, clinical battery used to assess balance in four component areas (anticipatory transitions, postural response, sensory orientation and dynamic gait) and provides a single number summary of balance performance. Scores range from 0 to 28 with higher scores indicate higher function.
up to 3 month follow-up
Freezing of Gait Questionnaire score
Time Frame: up to 3 month follow-up
The Freezing of Gait Questionnaire assesses freezing of gait (FOG) severity unrelated to falls in patients with Parkinson disease (PD), FOG frequency, disturbances in gait, and relationship to clinical features conceptually associated with gait and motor aspects. The total score ranges from 0-24, with higher scores representing greater severity of FOG symptoms.
up to 3 month follow-up
Hippocampal volume
Time Frame: up to 4 weeks
Hippocampal volume represents the size of the hippocampus, which is a portion of the deep brain. In particular, the investigators will compute the three dimensional volume of the hippocampus from structural MRI (Magnetic Resonance Imaging) taken at baseline and after 4 weeks of training.
up to 4 weeks
Fractional anisotropy
Time Frame: up to 4 weeks
Fractional anisotropy (FA) is derived from diffusion tensor imaging (DTI) sequences taken during the neuroimaging testing. FA reflects a ratio of the directional flows of water molecules within axonal bundles.
up to 4 weeks
