tDCS for Increasing Exercise Adherence in Depressed Individuals (StRIDE)

January 31, 2023 updated by: Butler Hospital

tDCS for Increasing Exercise Adherence in Individuals With Elevated Depressive Symptoms

The purpose of this study is to examine the efficacy of tDCS (transcranial direct current stimulation) for increasing exercise adherence among low active individuals with elevated depressive symptoms. The investigators expect that this project will contribute much needed knowledge about the role that tDCS can play in changing the affective experience of exercise.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Exercise adherence is a significant public health problem. Affective experiences during exercise predict long-term physical activity (PA) levels. Therefore, approaches to improving the affective experience of exercise are both important and likely to have high impact. This may be particularly true among individuals with elevated depressive symptoms due to their tendency toward more negative and less positive affect. tDCS is a noninvasive brain stimulation approach with a growing body of literature supporting its effects on cognitive and emotional processing in varied populations, including some support for those with depression. In addition, there is recent increased interest in utilizing tDCS in the context of exercise (see above) and in obesity prevention. While the effects of tDCS on behavioral and cognitive functioning are still developing, promising findings have emerged for tDCS used in repeated combination with a behavioral or cognitive intervention. Given that tDCS is relatively safe, inexpensive, and portable, individuals who struggle with enjoying exercise could be afforded a practical option for increasing and maintaining physical activity levels.

We propose to conduct a pilot randomized controlled trial of tDCS versus sham delivered 3x/week for 8 weeks in the context of a supervised aerobic exercise (AE) program among 72 low-active individuals with elevated depressive symptoms. Follow-up assessments will be conducted at end of treatment, 3, and 6 months.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: tDCS and Aerobic Exercise
Each participant will undergo a 20-minute session of transcranial direct current stimulation (tDCS) delivered to the dorsolateral prefrontal cortex (DLPFC). Each session of tDCS will be immediately followed by a supervised 30-minute, moderate-intensity bout of exercise. These procedures will occur 3x/week for 8 weeks.
Other: tDCS
Participants in transcranial direct current stimulation (tDCS) will receive tDCS over the dorsal-lateral prefrontal cortex for 20 minutes, 3 times per week for 8 weeks.
Behavioral: Aerobic Exercise (AE)
Participants will engage in supervised, 30-minute bouts of moderate-intensity exercise 3x/week for 8 weeks.
Sham Comparator: Sham tDCS and Aerobic Exercise
Each participant will undergo a 20-minute session of sham transcranial direct current stimulation (tDCS) delivered to the dorsolateral prefrontal cortex (DLPFC). Each session of tDCS will be immediately followed by a supervised 30-minute, moderate-intensity bout of exercise. These procedures will occur 3x/week for 8 weeks.
Behavioral: Aerobic Exercise (AE)
Participants will engage in supervised, 30-minute bouts of moderate-intensity exercise 3x/week for 8 weeks.
Other: Sham tDCS
Participants in sham transcranial direct current stimulation (tDCS) will receive shame tDCS over the dorsal-lateral prefrontal cortex for 20 minutes, 3 times per week for 8 weeks.
