NCT04576650
Locked-In Syndrome (LIS) is a devastating condition in which a person has lost the ability to communicate due to motor impairment, while being mentally intact. For people affected by this severe communication impairment, Brain-Computer Interfaces (BCI) may be the only solution that allows these people to start a conversation, ask questions, or request assistance (i.e. self-initiated communication). To-date, spelling was accomplished at a rate of 2-3 letters per minute with a predecessor device (the Medtronic Activa PC+S). To improve BCI performance, the current protocol will use the Medtronic Summit System, which offers a rechargeable battery and improved signal quality relative to Activa PC+S. Using signals from the motor hand/arm and/or motor mouth/face area, the investigators will investigate different avenues to improve the speed of communication using the Summit System. The primary objective is to evaluate the safety of the Summit System when used to chronically record subdural electrocorticographic (ECoG) signals in a BCI for use by patients with LIS in patients' homes. The secondary objective will be to evaluate the efficacy of the Summit System as a long-term source of ECoG signals for a BCI capable of allowing participants to control alternative and augmentative communication software in patients' homes.

It is well recognized that physical activity/exercise is an effective intervention to improve sleep, reduce pain and improve function in a variety of pain conditions. Traditional interventions to increase physical activity are challenging in older adults due to extensive staffing requirements and low adherence. The investigators plan to conduct a pilot trial in a cohort of older adults (without dementia) with both chronic musculoskeletal pain and nocturnal sleep complaints to test the effectiveness of a 12-week personalized behavioral intervention (compared to a control group) embedded within a smartwatch application in older adults. 27 cognitively intact elders were enrolled and randomly allocated to intervention or control group. Participants in the intervention arm received a 2-hour in person education session, and personalized, circadian-based activity guidelines, with real time physical activity self-monitoring, interactive prompts, biweekly phone consultation with the research team, and financial incentives for achieving weekly physical activity goal. The control group received general education on physical activity in older adults and continue routine daily activity for 12 weeks.
