What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to improve exercise habits among sedentary older Veterans by testing magnetic brain stimulation, known as repetitive transcranial magnetic stimulation (rTMS). Participants will use the Wii-Fit for home exercises to determine if it enhances balance and reduces falls. For those struggling with exercise adherence, some will receive either real or sham magnetic stimulation to assess its impact on maintaining the exercise regimen. Veterans who frequently spend long periods sitting, such as watching TV or engaging in seated hobbies, are well-suited for this trial. As a Phase 4 trial, the treatment is already FDA-approved and proven effective, and it seeks to understand its benefits for more patients.

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 is the safety track record for these treatments?

Research has shown that repetitive Transcranial Magnetic Stimulation (rTMS) is generally safe and well-tolerated. Studies have found that both low-frequency and high-frequency rTMS are safe, with mild side effects such as headaches or scalp discomfort. These side effects are usually temporary and not serious. Other studies have used rTMS for conditions like depression and obesity, further supporting its safety in humans. This study is a Phase 4 trial, indicating that earlier phases have already tested the treatment for safety and effectiveness. This suggests that rTMS is considered safe enough for wider use in clinical settings. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Researchers are excited about using repetitive transcranial magnetic stimulation (rTMS) for improving exercise adherence because it offers a novel approach by directly targeting the brain's neural circuits involved in motivation and reward. Unlike traditional methods like behavioral counseling or medication, which can have varying success rates and may rely on patient compliance, rTMS can potentially enhance motivation at a neurological level, which could lead to more consistent exercise habits. Additionally, the non-invasive nature of rTMS makes it an appealing option compared to more intrusive procedures, offering a safe and innovative way to address the challenge of maintaining exercise routines.

What evidence suggests that this trial's treatments could be effective for improving exercise adherence in older Veterans?

Research has shown that repetitive transcranial magnetic stimulation (rTMS), which participants in this trial may receive, can enhance brain functions such as planning and task completion. In past studies, rTMS proved promising in helping individuals adhere to exercise routines, especially when combined with physical activity. This combination also appears to improve mental health by reducing depression symptoms, which can, in turn, facilitate maintaining exercise habits. Additionally, rTMS can help the brain reorganize itself, potentially leading to better physical function and exercise adherence. This treatment already has approval for other conditions, like depression, indicating its potential to support exercise programs for older adults. ^{6 7 8 9 10}

In a meta-analysis of 93 randomized controlled trials involving repetitive transcranial magnetic stimulation (TMS), the overall incidence of adverse events (AEs) was found to be higher in the active TMS group (29.3%) compared to the placebo group (13.6%), indicating a 2.60 times greater risk of experiencing AEs with active treatment.

Despite the higher incidence of AEs, TMS is considered a safe and well-tolerated intervention, with common side effects including headache and dizziness, highlighting the importance of recognizing nocebo effects in both clinical trials and practice.

In a pilot study of 14 patients with medication-resistant major depressive disorder, repetitive transcranial magnetic stimulation (rTMS) significantly improved depression symptoms and sleep quality as measured by standard scales, but did not show significant changes in sleep patterns based on actigraphy data.

Interestingly, rTMS treatment led to a notable increase in daily physical activity, with participants taking more steps during the early sessions, suggesting that rTMS may enhance daytime activity levels even if it does not directly improve sleep disturbances.
