Community-based, Buddy-supported Exercise in Patients With MCI: a Pilot Trial

Intervention / Treatment
Detailed Description
The overall objective of this pilot study is to determine feasibility and gather data that will inform the design of a larger, multicenter, randomized, controlled trial. Specifically, the investigators aim to:
2.1 Determine the feasibility of recruiting persons with MCI and a buddy for an exercise intervention.
- For MCI participants who do not identify a buddy, the investigators will determine the interest and feasibility of recruiting volunteers from the community to be an exercise buddy.
2.2 Determine the effects of having an exercise buddy on:
- adherence to the protocol
- 400 meter walk time, an objective measure of improved physical fitness
- retention and satisfaction for both participant with MCI and buddy
2.3 Establish a scientific partnership with a community based exercise facility.

Description
Inclusion Criteria:
Participants:
- Age 60 and up
- Montreal Cognitive Assessment (MoCA) score 16-28
- CDR= 0.5 with memory box at least 0.5.
- Have a person (study partner) who can answer questions about their cognition for the CDR, FAQ and NPI-Q. This should be the same person who will come to all clinic visits whenever possible. This person can be called to answer these questions if unable to come into the clinic.
- Sedentary for past 3 months (< 45 min /wk of exercise, including walking)
- Able to walk 400 meters in < 15 min without assistance
- Willing to exercise 4 days a week at Body Check at CompRehab
- Physician approval for participation in the exercise intervention
Buddy:
- No report of memory problem
- MoCA score > 24 if > HS education; > 23 if 9-12 years; > 22 if ,< 9 years of education
Exclusion Criteria:
Due to Cognitive Confounders:
- Uncontrolled depression (PHQ-9 > 10)
- Schizophrenia or bipolar disorder
- Parkinson's disease
- Hachinski ischemic index > 4
- Daily use of highly anticholinergic medications (such as amitriptyline, diphenhydramine, scopolamine, etc) or benzodiazepines
- Use of stable dose of Cholinesterase inhibitors will be permitted. Must be on a stable dose for 4 weeks.
- Non-English speaking (as we are unable to administer the cognitive tests in languages other than English for this pilot)
- Vitamin B12 deficiency
- Uncontrolled hypothyroidism as measured by TSH blood test
Due to increased risk of or low likelihood of compliance with the exercise program:
- Active ischemic heart disease or angina
- symptomatic heart failure
- stroke
- screening blood pressure SBP > 170 or < 90; DBP > 100 or < 45
- Parkinson's disease or other neurologic disorder that might make exercise on a treadmill or bike unsafe
- Current or planned treatment for cancer
- peripheral artery disease that limits exercise capacity
- Severe respiratory-disease (e.g., COPD) that limits exercise capacity
- Severe arthritis that limits exercise capacity
- Serious conduction disorder, uncontrolled arrhythmia, or new Q waves or ST-segment depressions (> 3 mm) on ECG
- Severe anemia (Hgb < 8)
- Diagnosis of Diabetes and on medication
- Drinks more than 14 alcoholic drinks per week
- Dependent on a cane, walker or other device that would inhibit then from using a treadmill

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Buddy
Participant will be assigned a buddy that will meet with them at the gym for each of their exercise sessions.
This person will serve as a source of support and motivation for them and will also help them remember and stick to the goals set for you.
This person will also help them maintain their exercise logs and ensure they are correct.
The buddy will not be exercising with them, but will just be there with them while you exercise.
|
The 5-month aerobic exercise intervention is in accordance with the American Heart Association and American College of Sports Medicine physical activity recommendation for optimizing cardiovascular fitness in older adults.Exercise will consist primarily of walking on the treadmill.The goal of the program will be for participants to exercise at a moderate- to high-intensity, defined as 65-80% (ACSM guidelines) of heart rate reserve (HRR), for 30 minutes, 4 days per week.The duration of exercise will progress from 15-20 mins at 50% HRR the 1st week to 30 mins at 65-80% HRR by the end of the 6th week and thereafter.At the start of each session, exercise intensity will be gradually increased to 50% HRR(0.5[HRmax-HRrest]+HRrest)during a 10minute warmup period,and then to the individualized target heart rate training zone for the next 25-30 minutes.Participants will wear a digital heart rate monitoring device for the duration of the training session.
|
Placebo Comparator: Non Buddy
Participants will not be assigned a buddy (and are not allowed to bring someone with them as a buddy).
They will be asked to exercise on their own and remember the goals set for them.
They will also be responsible for filling out their own exercise logs and ensuring they are correct.
