Brief summary
The purpose of this research study is to investigate the effects of a home-based 3-month long walking exercise program on cognitive (thinking) performance in persons with TBI. As a participant, you will complete this 3-month exercise program now or after a 3-month wait period.
Detailed description
This study involves no in-person visits to Kessler Foundation and takes place at home. The first study activity will last about 1 hour in total and will involve using videoconferencing software (Zoom) to take tests of thinking (e.g., matching shapes and number, learning a list of words). You will then complete several brief questionnaires about everyday activities and TBI symptoms over the computer. You will then be randomly picked (like the flip of a coin) by a computer to participate in one of two groups. You will have a 50/50 chance of being placed in either group. One group will complete 3-months of walking exercise at home. The exercise program is based on activity guidelines for people with TBI and will be monitored by a trained exercise leader. You will be asked to walk 3 times per week. The first two weeks will require you to walk for 10 minutes at a time, and that duration will increase throughout the 3-months. You will have a dedicated trainer to help get started, answer questions, and support you throughout the programs. You will have regular meetings with this trainer by video conference (Zoom). You will be sent a FitBit to wear on your wrist while exercising to track your steps, and that you will be allowed to keep when the study ends. The other group will stick to a regular routine during this 3-month period (i.e., wait-list group). At the end of the 3-month exercise program, you will repeat the thinking tests and questionnaires. The wait-list group will be given the exercise prescription after this last Zoom session.

Eligibility
Inclusion criteria
* Definitive TBI diagnosis at least 1 year prior, verified by medical records * Self-report problems with thinking skills since the TBI diagnosis (e.g., processing information, learning or remembering, organizing, multitasking) * Between the ages of 18 and 65 * Access to internet and email * Fluent in English * Can walk at a brisk pace without using an assistive device * Not fallen due to mobility issues from their TBI in the past 6 months * Do not currently meet public health guidelines for physical activity * Have problems with thinking performance
Exclusion criteria
* I currently have uncontrolled major depression * I have a history of schizophrenia, bipolar disorder I or II, or substance-abuse disorders * I am regularly taking medications that can affect my thinking, such as antipsychotics or benzodiazepines. Study staff will review my medications to determine if I am taking any that would make me ineligible for this study * I have known/diagnosed cardiovascular disease including uncontrolled hypertension, diabetes, or kidney disease * I am unable to make everyday decisions on my own
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Adverse Events | Through study completion, which is 3 months for intervention and 6 months for wait list. | Safety will be primarily measured as adverse events, specifically during the remote walking intervention. |
| Adherence | Through study completion, which is 3 months for intervention and 6 months for wait list. | Adherence is measured as the number of exercise sessions attended compared to the number of total sessions prescribed. |
| Compliance | Through study completion, which is 3 months for intervention and 6 months for wait list. | Compliance will be measured as the number of exercise sessions completed as prescribed (i.e., intensity and duration). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Processing Speed | Baseline and follow-up (12-weeks post-baseline) | Neuropsychological assessments will be administered to measure processing speed using the symbol digit modalities test (SDMT). |
| Learning/Memory | Baseline and follow-up (12-weeks post-baseline) | Neuropsychological assessments will be administered to measure processing learning and memory using the California Verbal Learning Test (CVLT). |
| Executive function | Baseline and follow-up (12-weeks post-baseline) | Neuropsychological assessments will be administered to measure executive function using the Delis-Kaplan Executive Function System (DKEFS). |
