چکیده

Für querschnittgelähmte Menschen stellt das Herz-Kreislauf-Training an Fahrradergometern mit Funktioneller Elektrischer Stimulation (FES) der gelähmten unteren Extremitäten eine sich zunehmend etablierende Rehabilitationsmaßnahme dar. Diese Arbeit stellt ein neues Ergometersystem mit Elektrostimulation vor, bei dem die Beine zusätzlich durch einen Hilfsmotor unterstützt werden. Durch den Motor kann ein isokinetisches Training realisiert werden. Der Patient arbeitet in diesem Fall mit den elektrisch stimulierten Muskeln gegen den Motor, der die Trittgeschwindigkeit konstant hält. Für die gezielte Anpassung der Belastung durch die Elektrostimulation wurde ein sich selbst einstellender Momentenregler entwickelt. Der Reglerentwurf erfolgt anhand der online identifizierten linearen Übertragungsfunktion zwischen Stimulationsintensität und gemitteltem muskulären Antriebsmoment. Erste experimentelle Ergebnisse mit einem neurologisch intakten Probanden werden vorgestellt.

Distributed Nonlinear Robust Control for Power Flow in Islanded Microgrids

In this paper, a robust local controller has been designed to balance the power for distributed energy resources (DERs) in an islanded microgrid. Three different DER types are considered in this study; photovoltaic systems, battery energy storage systems, and synchronous generators. Since DER dynamics are nonlinear and uncertain, which may destabilize the power system or decrease the performanc...

Preprint : Shalaby R, Schauer T, Liedecke W, Raisch J. Amplifier design for EMG recording from stimulation electrodes during functional electrical stimulation leg cycling ergometry. Biomed Tech (Berl)

Functional electrical stimulation leg cycle ergometry (FES-LCE), which is often used as exercise for people with Spinal Cord Injury (SCI) has been recently applied in the motor rehabilitation of stroke patients. Recently completed studies show controversial results, but with a tendency to positive training effects. Technology involved at the moment is identical to the one used in FES-LCE for SC...

CLINICAL NOTES Response to Functional Electrical Stimulation Cycling in Women With Spinal Cord Injuries Using Dual-Energy X-ray Absorptiometry and Peripheral Quantitative Computed Tomography: A Case Series

Background: Loss of bone mass is common after spinal cord injury (SCI). One rehabilitation modality that has shown some promise for maintaining bone health is the functional electrical stimulation (FES) cycle ergometer. Although there has been some research investigating bone health and FES cycle ergometry, few have provided a detailed description of the changes that can occur in bone mass and ...
