Study summary

The goal of this research is to identify an intervention that will improve cognition and sleep in persons with PD.

Read the detailed description

Persons with Parkinson's disease (PD) often experience non-motor symptoms such as cognitive dysfunction and sleep problems. These symptoms can be more disabling than the motor symptoms of PD. Medications are often not effective for treating these non-motor symptoms or can have unwanted side effects. Non- medication treatments such as exercise are known to improve the motor symptoms of PD, but the effect of exercise on cognition and sleep has not been fully explored. This study investigates the impact of 16 weeks of supervised exercise, 3 times per week, compared to no-exercise over the same duration, on cognition and sleep dysfunction. Participants will be evaluated with cognitive tests and sleep studies before and after 16-weeks to determine the impact of this exercise intervention. The goal of this research is to identify an intervention that will improve cognition and sleep in persons with PD.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • a clinical diagnosis of idiopathic PD, based on the presence of bradykinesia as well as rest tremor and/or rigidity;
  • Hoehn and Yahr stage 2-3;
  • age ≥ 45;
  • on stable medications for at least 4 weeks prior to study entry;
  • Participants must have (MoCA) score ≥ 18;
  • No to an exercise program, based on the Physical Activity Readiness Questionnaire (PAR-Q), resting physical examination, and 12-lead .

Exclusion criteria

Exclusion Criteria:

  • features suggestive of atypical Parkinsonism (cerebellar signs, supranuclear gaze palsy, prominent autonomic failure, or prominent upper motor neuron signs);
  • secondary Parkinsonism (multiple strokes with stepwise progression of Parkinsonism, neuroleptic treatment at time of diagnosis, or multiple head injuries);
  • inability to walk without a cane or walker;
  • regular participation in an exercise program in the past 6 months;
  • presence of deep brain stimulator; and
  • untreated sleep apnea.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

MMSE and MoCA

Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

Study arms

  • Active comparator
    Exercise Group

    Subjects randomized to the exercise training group will complete 16 weeks of exercise training. Exercise training will be performed 3x/week.

    Other: Exercise training

  • Active comparator
    No Exercise Group

    Subjects randomized to the no-Ex group will receive a handout with tips for improving sleep hygiene. Additionally, study staff will provide the title page for a book on sleep relaxation techniques that is recommended for persons with sleeping difficulty.

    Behavioral: Sleep hygiene

Interventions

  • OtherExercise training

    Exercise training will be performed 3x/week. After 2 sessions, training volume and intensity will progress over the first 4 sessions ramping up the number of sets to increase the volume. The full volume prescription will consist of: 1) 5 movements to improve strength and muscle mass (leg press, knee extension, chest press, overhead press, pull down), 3 sets each of 8-12 repetitions (\~30 total repetitions); 2) trunk exercises to improve postural stability (trunk extension and flexion); 3) 3-4 bodyweight exercises (selected from a menu) to improve power and balance (e.g. step up, squat, jump squat, lunge, side lunge, push-up, assisted pull-up, assisted dip). Bodyweight movements will be modified as necessary to match abilities.

  • BehavioralSleep hygiene

    Subjects randomized to the no-exercise group will receive a handout with tips for improving sleep. Additionally, study staff will provide the title page for a book on sleep relaxation techniques that is recommended for persons with sleeping difficulty. Dr. Amara will review the sleep tips with the subjects and make recommendations for improving current sleep habits. Subjects will be contacted by telephone every 4 weeks during the 16-week intervention period.

What researchers measure

Primary outcomes

  1. Executive function (Stroop inhibition, Trails B-A, Controlled oral word association)

    Changes in executive function will be measured by a change in a composite executive function score calculated from the mean of z-scores for Stroop inhibition, Trails B-A, and COWA.

    Time frame: changes from baseline to week 16

  2. Sleep Efficiency

    Change in sleep efficiency (the number of minutes asleep divided by the number of minutes in bed) between the baseline nocturnal polysomnography to the post-16 weeks of intervention nocturnal polysomnography

    Time frame: changes from baseline and week 16

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2017 to primary completion in Nov 2018, 18 months.

Of 1,291 non-industry interventional studies with no phase under Parkinson Disease, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 44. This study's 18 months is below that.

Counting every sponsor, half of 1,367 studies reached it within 25 months; a quarter within 11 and three quarters within 44.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 26, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
