简要总结
Background:
Regular physical activity is an evidence-based adjuvant therapy of chronic heart failure or chronic lung diseases. Structured exercise training is safe, increases exercise capacity and quality of life, relieves symptoms and reduces hospitalization rates. Even a trend towards reduction of mortality has been identified. However, dyspnea and fatigue, typical symptoms of heart or lung failure, force patients to physical inactivity which fatally aggravates deconditioning and exercise intolerance, leading to an increased risk of hospitalization and a loss of independence and quality of life. To break through this vicious circle physical activity must be restored, since exercise intolerance can be successfully improved by physical training.
Purpose:
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 (fig. 1) assists mobilization according to individual needs by activating neuromuscular feedback systems, promoting physical activity and preventing early physical exhaustion. The investigators hypotheses that an exosuit-supported training increases exercise capacity and quality of life in a greater degree than non-supported training.
Methods:
The study will consist of two parts investigating i) the feasibility, tolerance and safety (n= 30) and ii) the efficacy of an exosuit device-supported training (n=30). In i) patients will perform a walking test and a set of everyday life skills or participate in a standardized rehabilitation sports program. In ii) 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.

结局指标
主要结局
Incidence of Treatment-Emergent Falls - Safety of the MyoSuit
时间窗: 1 hour
Patients with advanced heart or pulmonary failure will perform 6-minute walking tests and activities of daily life both with and without wearing a MyoSuit. Outcome is measured by documenting number of falls.
Incidence of Treatment-Emergent Adverse Events - Safety of the MyoSuit
时间窗: 1 hour
Patients with advanced heart or pulmonary failure will perform 6-minute walking tests and activities of daily life both with and without wearing a MyoSuit. Outcome is measured by documenting adverse events.
Exercise can be performed when wearing a MyoSuit - Feasibility and Tolerability of walking test, activities of daily life, rehabilitation exercise group.
时间窗: 1 hour
Patients with advanced heart or pulmonary failure will perform a 6 minute walking test, activities of daily life and a cardiac rehabilitation exercise unit. Outcome is measured dichotomously (yes/no) according to its feasibility.
Necessity of assistance in exercising when wearing a MyoSuit - Feasibility and Tolerability
时间窗: 1 hour
Patients with advanced heart or pulmonary failure will perform a 6 minute walking test, activities of daily lif and a cardiac rehabilitation exercise unit. Outcome is measured according to a scale of assistance needed (1=no assistance, 2=little assistance, 3=much assistance, 4=not possible). 1 is minimum, 4 is maximum. The higher the score, the worse the outcome.
MyoSuit assistance leads to changes in walking distance in patients with advanced heart or pulmonary failure assessed by 6-minute walking test.
时间窗: 30 minutes
Change of 6minute walk distance in meters will be assessed with and without MyoSuit in every participant.
