Exercise Dosing Trial for Individuals With Parkinson's Disease (PDEX)

November 1, 2022 updated by: Madaline Harrison, University of Virginia
This is a prospective, pre-post intervention study to evaluate the effect of a high-intensity, aerobic exercise program on outcomes of cognition, mood, gait, balance, cardiorespiratory fitness, neuromuscular performance, fatigue, sleep, and quality of life for patients diagnosed with idiopathic Parkinson disease. The primary outcomes will be a composite measure of cognitive function and the Timed Up and Go (TUG).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

All subjects will be assigned to aerobic exercise that will use a blend of both unsupervised moderate and supervised high intensity exercise. The exercise will consist of walking / jogging modalities, dependent on the individual's level of bradykinesia and will be paced by the individual's level of perceived exertion. The exercise protocol will be designed to target an accumulation of at least 150 minutes of cardiovascular exercise per week.

Exercise training will be performed 5x/week for a total of 16 weeks. The training will consist of 3 supervised high intensity sessions and 2 at home moderate intensity exercise sessions. The high intensity sessions will be performed on a treadmill at an intensity rating of ~ 15 and 17 on a rating of perceived exertion (RPE) scale of 6 to 20. The moderate intensity exercise will target an RPE of ~10 - 12 and participants will be asked to complete this on their own.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

45 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

  • Hoehn and Yahr stage 2 or 3.
  • Stable dopaminergic medication regimen for 4 weeks prior to baseline visit with no anticipated changes for the duration of the study.
  • Stable doses of medications known to affect sleep and medications for Parkinson's Disease for at least 4 weeks prior to study entry without anticipation of medication change for the duration of the study.
  • Ability to complete exercise intervention and assessment visits during at least 16 weeks of intervention (3x/week for 16 weeks).

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: High-intensity aerobic exercise
Subjects will participate in a 16 week high-intensity aerobic exercise program.
Other: High-intensity, aerobic exercise.

Aerobic exercise will blend unsupervised moderate and supervised high intensity exercise. It will consist of walking/jogging modalities, dependent on the subject's level of bradykinesia, paced by the subject's level of perceived exertion. The exercise protocol will be designed to target an total of at least 150 minutes of cardio exercise per week.

Exercise training will be performed 5 times per week for 6 weeks, consisting of 3 supervised high intensity sessions and 2 at home moderate intensity sessions. High intensity sessions will be performed on a treadmill at an intensity rating of ~ 15 and 17 on a rating of perceived exertion (RPE) scale of 6 to 20. The moderate intensity exercise will target an RPE of ~10 - 12 and participants will be asked to complete this on their own.
