GetUp&Go: A Randomized Controlled Trial of an Intervention to Enhance Physical Activity After TBI

Description

The investigators will conduct a Randomized Controlled Trial (RCT) of a novel, remotely delivered physical activity (PA) promotion program, called GetUp&Go-a name selected by focus group participants with moderate-to-severe traumatic brain injury (msTBI). It will be theoretically based, use objective measurement of PA as a primary outcome, and incorporate varied types and amounts of home- and neighborhood-based PA and ways to reduce sedentary behavior, according to participant preferences. Moreover, using a 2-phase design as described below, the investigators will test a method for enhancing longer-term gains in PA using mobile technology, in addition to gains acquired during the first phase of intervention.

Trial design. Participants will undergo baseline testing (T1) and will then be randomized 1:1 to either immediate treatment in GetUp&Go (IT) or waitlist (WL) for 10 weeks. After testing for the primary outcome (T2), the waitlist group will receive GetUp&Go for 10 weeks followed by a T2b evaluation for that group. This phase is called the “A phase”, for Acquisition.

Following completion of the GetUp&Go intervention, all participants-regardless of initial group allocation-will be randomized 1:1 to one of two conditions for an additional 10 weeks, the “Follow-Through” (FT) phase. Half of participants will be randomized to the RehaBot condition (RB), which provides continued use of the chatbot to support individualized PA plans, but with no further therapist contact. Participants in the No RehaBot (No RB) condition will not have access to the chatbot. The final evaluation, T3, will occur after the 10-week Follow-Through phase.
