All participants who have been found eligible for this study and given informed consent will be randomized into two groups- either participants will begin ReTrieve training immediately following an initial assessment, or wait 8 weeks before beginning training.~During the study, participants will have a ReTrieve tactile training system delivered home for use over 6 weeks. Investigators will take three days to teach participants how to use the system. Each week for the remainder of the 6 weeks, participants will use this system for 4+ days per week on their own, and for 1 day supervised. During each supervised day, participants will complete approximately 1 hour of training while supervised over video chat with researchers.~Participants' tactile function will be assessed at three separate time points: once within one week before beginning training, once within one week after completing training, as well as once either 8 weeks before or 8 weeks after the training. This assessment has a required survey component, as well as an optional in-person clinical assessment component.
Researchers aim to determine whether the ReTrieve system for tactile training can improve tactile function (sense of touch) in the hand after brain injury when used at home for 6 weeks.
