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

Intervention model description
The proposed study is a randomized, controlled, interventional study to investigate the impact of a novel exercise intervention on executive dysfunction (Aim 1) and objective sleep outcomes (Aim 2) in patients with PD. Thirty participants with idiopathic PD will be recruited from the University of Alabama at Birmingham (UAB) Movement Disorders Center and randomized (1:1) to one of two groups (15 per group): exercise intervention (Ex) group or no-exercise (no-Ex) control group.

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 Montreal Cognitive Assessment (MoCA) score ≥ 18; * No contraindications to an exercise program, based on the Physical Activity Readiness Questionnaire (PAR-Q), resting physical examination, and 12-lead electrocardiogram.
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.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Executive function (Stroop inhibition, Trails B-A, Controlled oral word association) | changes from baseline to week 16 | 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. |
| Sleep Efficiency | changes from baseline and week 16 | 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 |
