AI Muscle Longevity System is an AI-powered medical device and home muscle management system designed to help older adults and people with limited mobility maintain muscle strength, mobility, and functional independence through personalized assessment, muscle activation, and exercise guidance. It combines functional assessment with five portable EMS/NMES modules for targeted muscle activation. Using rPPG camera assessment, IMU motion sensing, functional test results, and device data, the AI coach identifies priority muscle groups, recommends personalized routines, and guides exercises appropriate to each user’s functional condition. Wearable modules provide targeted muscle stimulation to complement active exercise, while body-map guidance and contact-aware controls simplify electrode placement and support safe, independent use. The system tracks movement performance, routine completion, and usage history to refine future recommendations, creating an adaptive home experience that reduces barriers to sustained muscle conditioning and supports continued physical function as users age.
