Neuromodulation for Exercise Adherence
Trial Summary
What is the purpose of this trial?
Lack of adherence to an exercise program is a major problem for older Veterans. Several fall prevention programs fail in the home setting due to lack of adherence. Exercise adherence is dependent on brain function among other factors. Magnetic stimulation of the front part of the brain improves brain function necessary for planning and following-through. The investigators propose a three-phase study in 106 sedentary older Veterans. Everyone will be trained on use of the exergame, Nintendo Wii-Fit, that the investigators' team has found beneficial in improving balance and gait. They will be asked to exercise using Wii-Fit at home for 45 minutes daily five days/week for 12-weeks. Those that exercise less than recommended dose and those that exercise adequately but have low executive function will receive either real or sham magnetic stimulation to the front part of their brain over ten sessions paired with exercise training. All subjects will further complete 24-weeks of Wii-Fit home exercises. Adherence, executive function, balance and gait, self-efficacy, delay discounting, and falls will be measured periodically.
Will I have to stop taking my current medications?
The trial requires that you stop taking certain medications that increase the risk of seizures, such as bupropion, chlorpromazine, clozapine, and tricyclic antidepressants. If you are on these medications, you may need to stop them to participate.
What data supports the effectiveness of the treatment Neuromodulation for Exercise Adherence?
Is neuromodulation using transcranial magnetic stimulation (TMS) safe for humans?
Transcranial magnetic stimulation (TMS), including its repetitive (rTMS) and deep (dTMS) forms, is generally considered safe for humans, with most studies showing a reassuring safety profile. However, there have been some reports of adverse events, such as seizures, though these are rare. Overall, TMS is well-tolerated, but monitoring and guidelines are recommended to ensure safety.678910
How does the treatment in the Neuromodulation for Exercise Adherence trial differ from other treatments?
The treatment in this trial likely involves neuromodulation techniques such as repetitive transcranial magnetic stimulation (rTMS), which is a non-invasive method that uses magnetic fields to stimulate nerve cells in the brain. This approach is unique because it targets brain activity directly, unlike traditional exercise adherence methods that may focus on behavioral or motivational strategies.35111213

Eligibility Criteria
This trial is for sedentary Veterans aged 60+ who spend a lot of time sitting daily and have a TV at home. It's not for those who are already physically active, use wheelchairs, have significant cognitive impairments, weigh over 325 lbs., or have health conditions that make exercise unsafe. People taking certain medications or with a history of seizures, stroke, bipolar disorder, or abnormal EEGs can't join.Inclusion Criteria

Timeline
Screening
Participants are screened for eligibility to participate in the trial
Phase I: Facility-based Exercise
Participants undergo two weeks of facility-based exercise for safety assessment and learning the program, followed by 12 weeks of home-based exercises.
Phase II: rTMS or Sham Treatment
Participants with poor adherence or low executive function receive 10 consecutive weekdays of rTMS or sham treatment along with exercise training.
Phase III: Home-based Exercise Program
All subjects continue with 24 weeks of a home-based exercise program.
Follow-up
Participants are monitored for adherence, executive function, balance, gait, self-efficacy, delay discounting, and falls.
