Previous studies investigating the blood oxygen level-dependent (BOLD) signal in the human sensorimotor cortex during static force (maintained for a few seconds) and dynamic force (repetitive force pulses) resulted in contradictory findings. Therefore, we conducted a whole-brain functional magnetic resonance imaging study during a visuomotor task requiring(More)
Force scaling in the sensorimotor network during generation and control of static or dynamic grip force has been the subject of many investigations in monkeys and human subjects. In human, the relationship between BOLD signal in cortical and subcortical regions and force still remains controversial. With respect to grip force, the modulation of the BOLD(More)
The main scope of this study was to test the feasibility and reliability of FES in a MR-environment. Functional Electrical Stimulation (FES) is used in the rehabilitation therapy of patients after stroke or spinal cord injury to improve their motor abilities. Its principle lies in applying repeated electrical stimulation to the relevant nerves or muscles(More)
The process of developing a successful stroke rehabilitation methodology requires four key components: a good understanding of the pathophysiological mechanisms underlying this brain disease, clear neuroscientific hypotheses to guide therapy, adequate clinical assessments of its efficacy on multiple timescales, and a systematic approach to the application(More)
Introduction Recovery of patients with spinal cord injury can only be successful, if patients are not immobile over a long time, because immobility results in a loss of neuronal function. In order to keep the patients mobile, new locomotor training devices (e.g. the LOKOMAT – a robotic gait orthosis manufactured by Hocoma AG, Switzerland) have been(More)
We investigated the feasibility of studying brain responses to controlled arm movements supported by an fMRI-compatible robotic interface. The study can be used in neurorehabilitation to provide insight into the cortical reorganization mechanism after damage to the nervous system, allow a better understanding of therapy-induced recovery and assist the(More)
