Researchers at the Technical University of Munich (TUM) have developed a modular system that helps stroke patients regain movement in paralyzed arms and hands shortly after the event. The system combines an exoskeleton, targeted electrical stimulation, and a digital twin to provide personalized support.

Wolfgang Korisanski is one of 24 patients who tested the new system at the Schön Klinik Bad Aibling, where a study is currently underway. Using functional electrical stimulation (FES), the system activates specific muscles in the forearm while the exoskeleton supports the entire arm. A computer game adjusts in real time to the user’s capabilities, encouraging independent and engaging rehabilitation.
At the heart of the technology is a digital twin that integrates muscle activity, stimulation levels, and exoskeleton support into a closed-loop control system. This allows for intention-based movement and tailored therapy – even at home.
