Planning, Reminders and Micro-incentives to Increase Walking After Traumatic Brain Injury in Older Adults
The purpose of this research is to learn if different behavioral interventions can change walking behaviors over 12-weeks, in older adults who have previously suffered a non-penetrating mild or moderate TBI. Participants will provide information and be screened for eligibility via phone screening call (verification of age, confirmation that the participant is not currently on any medication that affects the central nervous system, and verification that the subject can participate in exercise, brief TBI history). Baseline testing will take place at the Center for Cognitive and Brain Health and Northeastern University Biomedical Imaging Center, for the baseline magnetic resonance imaging, in the interdisciplinary science and engineering complex on Northeastern University's campus. In person testing will take place over one session. The study period lasts 12 weeks, during which all participants will 1. Receive a weekly phone call with study staff and 2. Wear a wrist-worn Fit Bit tracker. A remote participation option is available for those who cannot travel to Northeastern University.
⁃ • Suffered a mild or moderate traumatic brain injury within 3 months to 15 years prior to recruitment.
⁃ \* TBI history will be assessed using the validated OSU TBI history questionnaire (Attachment 1). TBI severity will be defined as loss of consciousness of 0-30 minutes (mild) or \>30 minutes and \<24 hours (moderate). If no loss of consciousness was reported but post-traumatic amnesia was reported, then this is considered a mild TBI.
⁃ If clinical reports from the time of injury are available and Glasgow Coma Scale scores are available, then 13-15 is considered mild and 9-12 moderate. A clinical neurologist will review the de-identified OSU TBI forms for accuracy and confirm TBI severity.
• Men and women of all ethnicities/races and socio-economic status.
• 40-80 years.
• Signed Informed consent.
• Physically fit enough to undergo exercise as screened using the Physical Activity Readiness Questionnaire (PAR-Q) and the cardiovascular section of the Health History \& Demographics Questionnaire. An affirmative response (i.e., \"yes\") to any single item regarding an individual's health status is grounds for the necessary medical clearance before enrollment.
• Normal or corrected-to-normal vision based on the minimal 20/20 standard in order to complete the cognitive tasks (below 20/20 vision).
• Able to speak, read, and write English.
• Ambulatory without pain or the assistance of walking devices.
• Reliable means of transportation (if participating in Boston).
• No diagnosis of a neurological disease.
• No intracerebral brain bleeds.
• Access to a mobile device, laptop or desktop computer with internet access and Bluetooth.
