简要总结
This study will address the challenging task of remobilizing patients with advanced chronic lung or heart failure in a functional New York Heart Association class III-IV by using an externally physically-supported exosuit movement therapy. This soft, wearable robot (Myosuit) assists mobilization according to individual needs by activating neuromuscular feedback systems, promoting physical activity and preventing early physical exhaustion.
The feasibility, tolerance and safety of a Myosuit assisted training was shown in a feasibility trial. In the efficacy trial, patients will be randomized in a 2:1 ratio for an exosuit-supported or non-supported exercise training protocol, training 3 units per week for 8 weeks. Assessment of outcome will be performed by various functional, mobility and endurance tests, questionnaires and clinical parameters. Furthermore, the transfer of regained motor and balance skills to everyday life will be analyzed.
