About this study

Official title: Modulating Brain Activity to Improve Goal-directed Physical Activity in Older Adult

Although the majority of older adults are aware of the compelling evidence that regular exercise is critical to the maintenance of health into old age, most do not meet recommendations for daily exercise. This lack of engagement in 'goal-directed' physical activity stems from numerous interrelated factors including lack of motivation, depressed mood, and cognitive "executive" impairments that diminish one's ability to regulate behavior over time. Intriguingly, each of these factors has been linked to the function of brain networks that include the left dorsolateral prefrontal cortex (dlPFC). Transcranial direct current stimulation (tDCS) is a noninvasive and safe means of modulating the excitability of specific brain regions and their connected neural networks. tDCS designed to facilitate the excitability of the left dlPFC has been shown to improve motivation, mood, and multiple aspects of executive function in healthy adults. The investigators thus hypothesize that tDCS holds promise to increase goal-directed physical activity in older adults. This project aims to conduct a pilot randomized controlled trial on the feasibility and effects of a 2-week, 10-session tDCS intervention targeting the left dlPFC, combined with behavioral intervention aimed at increases daily physical activity, on physical activity over a two-month follow-up period, in relatively sedentary older adults without overt illness or disease.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Transcranial direct current stimulation (tDCS)Device

    tDCS will be delivered via six gel electrodes with placement and current parameters optimized based on a standard brain to maximize the average normal component of the generated electric field over the left dlPFC. Current delivered by anyone electrode will never exceed 2.0 mA; the total amount of current from all electrodes will not exceed 4 mA. Each 20-minute session will begin and end with a 60-second ramp up/down of current amplitude to maximize comfort.

  • Sham stimulationDevice

    An 'active' sham will be used in which very low-level currents are transferred between the same electrodes used in the active condition throughout the 20-minute session. However, currents will be designed to mimic the cutaneous sensations induced by tDCS yet not significantly influence cortical tissue.

  • Behavioral intervention to increase physical activityBehavioural

    Study staff will complete face-to-face and telephone counseling sessions with each participant, tailored to their state of readiness to increase physical activity levels. The participant will be provided with a goal to increase their average daily step count by 20% from baseline. The staff member will review the participant's stated barriers to exercise and provide them with a list of strategies they may use to augment their step counts throughout each day. Bi-weekly face-to-face counseling sessions will then be completed to review and discuss activity performance and answer any questions the participant may have regarding their efforts to increase physical activity.

Behavioral intervention plus tDCSExperimentalThis intervention will consist of a two-month, personalized, goal-based counseling approach to promote physical activity. Over the first two weeks of the behavioral intervention, participants will also received 10, once-daily, 20-minute sessions of transcranial direct current stimulation (tDCS) designed to increase the excitability of the left dorsolateral prefrontal cortex.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change of Daily Step Counts From Baseline

    Absolute change in averaged daily step counts from two-week baseline (first two weeks, week 1-2). The specific periods are 1) absolute change in averaged daily step counts in week 3 and 4 from baseline, 2) absolute change in averaged daily step counts at week 5 and 6, from baseline, 3) absolute change in averaged daily step counts in week 7 and 8 from baseline, and 4) absolute change in averaged daily step counts in week 9 and 10 from baseline.

    Measured: Week 3-4, Week 5-6, Week 7-8, and Week 9-10.

Secondary outcomes (8)
  1. Motivation - External Regulation Score

    External Regulation Score was calculated from the Exercise Self-Regulation Questionnaire (SQR-E). External regulation refers to motivation based on external sources such as incentives or coercion. Introjected regulation refers to motivation from an internalized, pressuring voice that was not accepting it as one's own. The External Regulation Score ranges from 4 to 28. The higher scores mean a better outcome.

    Measured: Baseline; Week 4; Week 10

  2. Timed Up-and-Go (TUG)

    A common field test of mobility

    Measured: Baseline; Week 4; Week 10

  3. Trail Making Test (TMT) - A

    Trail making test (TMT) A is a neuropsychological test of visual attention. The test requires the patient to connect randomly positioned numbered circles in numeric order as quickly as possible. It provides information about visual search speed and speed of processing. The test reliability for TMT A is 0.82. Time is measured in seconds.

    Measured: Baseline; Week 4; Week 10

  4. Trail Making Test (TMT) - B

    Trail Making Test (TMT) - B is a neuropsychological test of task switching. The test requires the participants to connect the circles in numeric and alphabetic order as quickly as possible, alternating between numbers and letters. It provides information about executive function. The test reliability for TMT-B is 0.93. Time is measured in seconds.

    Measured: Baseline; Week 4; Week 10

  5. Montreal Cognitive Assessment (MoCA) Total Score

    Global cognitive function. The range for this test is 0-30, with higher score representing better outcome.

    Measured: Baseline; Week 4; Week 10

  6. Geriatric Depression Scale (15-item)

    Number of depressive symptoms. The range for this test is 0-15, with lower score representing better outcome.

    Measured: Baseline; Week 4; Week 10

  7. Completion Rate for Brain Stimulation Sessions

    Ten stimulation sessions were planned for each participant over two weeks. This outcome presents the percentage of the completed brain stimulation sessions.

    Measured: Week 4

  8. Completion Rate for Behavior Sessions

    Four bi-weekly behaviors sessions were planned for each participant over two months. This outcome presents the percentage of the completed behavior sessions.

    Measured: Week 10
