  Purpose

The propose of this study is to evaluate the feasibility and the clinical efficiency of feedback-controlled robotics-assisted treadmill exercise (RATE) technology for cardiovascular rehabilitation early after stroke. The investigators hypothesize that feedback-controlled RATE might be suitable and effective to improve cardiovascular fitness and functional carryover in non-ambulatory individuals with sub-acute stroke.

Primary Outcome Measures:
  • Aerobic capacity [ Time Frame: Baseline (T0), after 4 weeks intervention (T1, Tx, Tx..), at clinical discharge (Tx) / Expected time to clinical discharge: 8 weeks ] [ Designated as safety issue: No ]
    Peak oxygen uptake (VO2peak), peak work rate (WRpeak), peak heart rate (HRpeak), peak expiratory volume (VEpeak), peak respiratory exchange ration (RERpeak), gas exchange threshold (GET), time constants of oxygen on-/off-kinetics (τ), steady-state increase in oxygen uptake (ΔVO2), steady-state increase in heart rate (ΔHR), steady-state increase in expiratory volume (ΔVE)


Secondary Outcome Measures:
  • 10 Meter Walk Test (gait speed) [ Time Frame: Baseline (T0), after 4 weeks intervention (T1, Tx, Tx..), at clinical discharge (Tx) / Expected time to clinical discharge: 8 weeks ] [ Designated as safety issue: No ]
  • 6 Minute Walk Test (walking endurance) [ Time Frame: Baseline (T0), after 4 weeks intervention (T1, Tx, Tx..), at clinical discharge (Tx) / Expected time to clinical discharge: 8 weeks ] [ Designated as safety issue: No ]
  • Standing function (balance) [ Time Frame: Baseline (T0), after 4 weeks intervention (T1, Tx, Tx..), at clinical discharge (Tx) / Expected time to clinical discharge: 8 weeks ] [ Designated as safety issue: No ]
  • Stroke Impact Scale (stroke recovery) [ Time Frame: Baseline (T0), after 4 weeks intervention (T1, Tx, Tx..), at clinical discharge (Tx) / Expected time to clinical discharge: 8 weeks ] [ Designated as safety issue: No ]
  • Feasibility (criteria for success) [ Time Frame: Baseline (T0), after 4 weeks intervention (T1, Tx, Tx..), at clinical discharge (Tx) / Expected time to clinical discharge: 8 weeks ] [ Designated as safety issue: No ]
