The goal of this SBIR Phase I project is to develop and evaluate the feasibility of MiGo Plus, an activity-based, peer-supported social network to improve motor capacity and performance as well as provide support for individuals with stroke throughout their recovery and improve their quality of life. MiGo Plus uses custom wrist and hip-worn sensors developed and validated for individuals with stroke to monitor their arm and walking activity, along with a smartphone app to connect users with other stroke survivors for encouragement and collaboration. Project objectives include (1) developing the MiGo Plus smartphone app, (2) developing the cloud infrastructure required for the MiGo Plus social features; and (3) performing a one-month remote usability and feasibility study with 50 individuals with chronic stroke (months 5-6). Project outcomes include (1) performing numerous social interactions and activities with MiGo Plus to validate feasibility before safety and efficacy testing, and (2) processing quantitative and qualitative end-user feedback to improve the MiGo Plus system.
