What You Need to Know Before You Apply

What is the purpose of this trial?

This study is a Phase 3 multi-site, randomized, evaluator-masked, study of endurance treadmill exercise on changes in the Movement Disorder Society-Unified Parkinson Disease Rating Scale (MDS-UPDRS) Part III score at 12 months among persons with early stage Parkinson disease. 370 participants will be randomly assigned to 2 groups: 1)60-65% HRmax or 2)80-85% HRmax 4 times per week. The primary objective is to test whether the progression of the signs of Parkinson's disease is attenuated at 12 months in among persons who have not initiated medication for Parkinson Disease (PD) when they perform high-intensity endurance treadmill exercise.

Will I have to stop taking my current medications?

Yes, if you are currently taking medications for Parkinson's disease, you will need to stop them to participate in this trial. The study excludes anyone who has used Parkinson's medications like levodopa or dopamine agonists in the 60 days before the trial starts.

Is high-intensity treadmill exercise safe for people with Parkinson's disease?

Research shows that high-intensity treadmill exercise is generally safe for people with Parkinson's disease and does not worsen symptoms. ^{1 2 3 4 5}

How does high-intensity treadmill exercise differ from other treatments for Parkinson's disease?

High-intensity treadmill exercise is unique because it focuses on improving walking capacity and gait through structured, repetitive walking sessions, which may lead to positive changes in the brain's ability to adapt (neural plasticity). Unlike medications, this treatment directly targets physical symptoms like stride length and speed, and its benefits can persist even after the exercise sessions have ended. ^{2 6 7 8 9}

What data supports the effectiveness of the treatment High-Intensity Treadmill Exercise for Parkinson's Disease?

Research shows that treadmill training can improve walking speed, stride length, and overall quality of life for people with Parkinson's disease. Additionally, endurance exercise on a treadmill is known to enhance fitness, gait, and mobility, and may even slow disease progression. ^{2 6 9 10 11}

Published Research Related to This Trial

Treadmill training (TT) has shown immediate benefits for patients with Parkinson's disease, such as improved walking speed and stride length after just one session, with effects lasting for at least 15 minutes.

Long-term studies indicate that TT is feasible, safe, and effective in enhancing gait and overall quality of life for patients, suggesting potential positive changes in brain function, but more high-quality research is needed to firmly establish these findings.

Treadmill training for the treatment of gait disturbances in people with Parkinson's disease: a mini-review. Herman, T., Giladi, N., Hausdorff, JM.[2022]

Patients with Parkinson's disease (PD) showed significant improvements in their walking patterns when using a treadmill, including increased step length and height, and reduced cadence and step width variability.

Treadmill walking helped PD patients reduce their characteristic short shuffling steps, suggesting that treadmill training could be beneficial for gait modifications in these individuals.

Resistance training (RT) and endurance training (ET) are safe and feasible exercise modalities for people with Parkinson's disease, showing significant benefits in muscle strength, functional capacity, and quality of life based on a review of 33 new randomized controlled trials.

RT demonstrated a strong positive impact on muscle strength (SMD = 0.83) and functional capacity, while ET improved cardiorespiratory fitness (SMD = 0.27) and also showed potential benefits for functional outcomes, indicating that both types of exercise can be effective adjunct therapies for managing Parkinson's disease.

This study is a Phase 3 clinical trial involving 370 participants with Parkinson's disease, aiming to determine if high-intensity endurance exercise can slow disease progression compared to moderate-intensity exercise over 18 months.

The primary outcome will be measured using the MDS-UPDRS motor score, and if successful, this research could lead to a significant breakthrough in Parkinson's treatment, improving the quality of life for patients and their caregivers.

In a pilot study involving 17 patients with mild to moderate Parkinson's disease, those who underwent 12 sessions of treadmill training showed significant improvements in cognitive and motor performance compared to a control group that did not train.

The treadmill training group demonstrated better scores on the Frontal Assessment Battery and improved performance on the 6-minute walking test, suggesting that this type of exercise could be beneficial for managing symptoms of Parkinson's disease.

Treadmill training has been shown to significantly improve gait speed and stride length in patients with Parkinson Disease, based on a systematic review of 18 trials, indicating its potential effectiveness in rehabilitation.

The training was found to be safe, with no increase in dropout rates or reported adverse events, suggesting that it is an acceptable therapy for patients.

A 15-week multicomponent rehabilitation program that included water and land-based exercises significantly improved disease impact and quality of life in Parkinson's disease patients, as measured by the UPDRS and PDQ-39 scales.

Adding treadmill training to the water and land-based exercise program did not provide additional benefits for quality of life or disease impact, suggesting that the treadmill component may have limited effects in this context.

Individuals with Parkinson disease (PD) who take at least 4200 steps daily are significantly more likely to meet physical activity guidelines, being 23 times more likely than those who take fewer steps.

High-intensity treadmill exercise effectively increases daily steps and moderate-to-vigorous physical activity in less active individuals with PD, but these increases do not correlate with improvements in fitness.

In a study of 82 participants with Parkinson disease, most walking occurred at low intensities, with an average of 157.3 minutes spent walking at the lowest intensity level (1-19 steps per minute), indicating a need for interventions to promote higher intensity walking.

Despite high daily step counts, participants engaged in few sustained walking bouts lasting 20 minutes or more, highlighting the importance of encouraging longer and more intense walking sessions for potential health benefits.

Multidirectional treadmill training (MDTT) significantly improved gait and balance in individuals with Parkinson disease (PD) after just one session, with notable enhancements in stride length and turning ability.

Training for six weeks yielded the best long-term improvements in gait speed and balance, suggesting that this duration may be optimal for rehabilitation in PD patients.

Robotic treadmill training significantly improved functional mobility and walking capacity in patients with mild to moderate Parkinson's disease, as evidenced by better scores in the Timed Up and Go test, 10 meter walking test, and UPDRS motor subscale after 5 weeks of training.

While the training led to a temporary enhancement in quality of life, measured by the Parkinson's Disease Questionnaire-39, these improvements reverted to baseline levels by the 12-week follow-up, indicating that ongoing training may be necessary for sustained benefits.
