Acknowledgements. Abstract Acquisition of skillfulness is not only characterized by a task-appropriate application of muscular forces but also by the ability to adapt performance to changing task demands. Previous research suggests that there is a different developmental schedule for adaptation at the kinematic compared to the neuro-muscular level. The purpose of this study was to determine how...

Multisystem deterioration occurs mainly in older individuals and may be related to physiological tissue degeneration. However, genetic predisposition may be unmasked by inappropriate functional and structural system deficiencies. McLeod syndrome (MLS) is a rare, multisystem disease which is X-chromosomal inherited and belongs to the neuroacanthocytosis syndromes (NAS). The main clinical manifes...

contribution presents a new approach to human arm position control under electrical stimulation that employs an acceleration feedback. During stimulation of antagonistic muscle pairs, this approach can noticeably reduce negative effects that are caused by an uncertain dead-zone within the muscular activation. The acceleration controller, realised using a disturbance observer, represents the low...
