BACKGROUND Motor imagery (MI) is increasingly recognized as a treatment option after stroke, but not all stroke patients are able to perform MI. OBJECTIVE To examine if severe somatosensory deficits would affect MI ability. METHODS The Box and Block Test (BBT) was used to evaluate mental chronometry as 1 component of MI. Two groups of stroke patients(More)
BACKGROUND AND PURPOSE Both action observation (AO) and action imagery have been proposed as therapeutic options for stroke rehabilitation. Currently, it is not clear to what extent their underlying neuronal mechanisms differ from each other and whether one of these therapeutic options might be preferable for this purpose. METHODS Twenty-six(More)
PURPOSE Recent studies have found age-related BOLD signal changes in several areas of the human brain. We investigated whether such changes also occur in brain areas involved in the processing of motor action observation and imagery. METHODS Functional magnetic resonance imaging with an experimental paradigm in which motor acts had to be observed and/or(More)
PURPOSE Mental training appears to be an attractive tool in stroke rehabilitation. The objective of this study was to investigate whether any differences in the processing of action observation and imagery might exist between patients with left and right hemisphere subcortical strokes. METHODS Eighteen patients with strictly subcortical stroke (nine(More)
PURPOSE The loss of calculation skills due to brain lesions leads to a major reduction in the quality of life and is often associated with difficulties of returning to work and a normal life. Very little is known about the neural mechanisms underlying performance improvement due to calculation training during rehabilitation. The current study investigates(More)
